COVID-19 Vaccination and Testing; Emergency Temporary Standard

AGENCY: Occupational Safety and Health Administration (OSHA), 
Department of Labor.

ACTION: Interim final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: The Occupational Safety and Health Administration (OSHA) is 
issuing an emergency temporary standard (ETS) to protect unvaccinated 
employees of large employers (100 or more employees) from the risk of 
contracting COVID-19 by strongly encouraging vaccination. Covered 
employers must develop, implement, and enforce a mandatory COVID-19 
vaccination policy, with an exception for employers that instead adopt 
a policy requiring employees to either get vaccinated or elect to 
undergo regular COVID-19 testing and wear a face covering at work in 
lieu of vaccination.

DATES: The rule is effective November 5, 2021. The incorporation by 
reference of certain publications listed in the rule is approved by the 
Director of the Federal Register as of November 5, 2021.
    Compliance dates: Compliance dates for specific provisions are in 
29 CFR 1910.501(m).
    Comments: Written comments, including comments on any aspect of 
this ETS and whether this ETS should become a final rule, must be 
submitted by December 6, 2021 in Docket No. OSHA-2021-0007. Comments on 
the information collection determination described in Additional 
Requirements (Section V.K. of this preamble) (OMB review under the 
Paperwork Reduction Act of 1995) may be submitted by January 4, 2022 in 
Docket No. OSHA-2021-0008.

ADDRESSES: In accordance with 28 U.S.C. 2112(a), the Agency designates

I. Executive Summary and Request for Comment

A. Executive Summary

    This ETS is based on the requirements of the Occupational Safety 
and Health Act (OSH Act or Act) and legal precedent arising under the 
Act. Under section 6(c)(1) of the OSH Act, 29 U.S.C. 655(c)(1), OSHA 
shall issue an ETS if the agency determines that employees are subject 
to grave danger from exposure to substances or agents determined to be 
toxic or physically harmful or from new hazards, and an ETS is 
necessary to protect employees from such danger. These legal 
requirements are more fully discussed in Pertinent Legal Authority 
(Section II. of this preamble). This ETS does not apply to workplaces 
subject to E.O. 14042 on Requiring Coronavirus Disease 2019 Vaccination 
for Federal Contractors. In addition, OSHA will treat federal agencies' 
compliance with E.O. 14043, and the Safer Federal Workforce Task Force 
guidance issued under section 4(e) of Executive Order 13991 and section 
2 of Executive Order 14043, as sufficient to meet their obligations 
under the OSH Act and E.O. 12196.
    COVID-19 has killed over 725,000 people in the United States in 
less than two years, and infected millions more (CDC, October 18, 
2021--Cumulative US Deaths). The pandemic continues to affect workers 
and workplaces. While COVID-19 vaccines authorized or


approved by the U.S. Food and Drug Administration (FDA) effectively 
protect vaccinated individuals against severe illness and death from 
COVID-19, unvaccinated individuals remain at much higher risk of severe 
health outcomes from COVID-19. Further, unvaccinated workers are much 
more likely to contract and transmit COVID-19 in the workplace than 
vaccinated workers. OSHA has determined that many employees in the U.S. 
who are not fully vaccinated against COVID-19 face grave danger from 
exposure to SARS-CoV-2 in the workplace. This finding of grave danger 
is based on the severe health consequences associated with exposure to 
the virus along with evidence demonstrating the transmissibility of the 
virus in the workplace and the prevalence of infections in employee 
populations, as discussed in Grave Danger (Section III.A. of this 
preamble).
    OSHA has also determined that an ETS is necessary to protect 
unvaccinated workers from the risk of contracting COVID-19 at work, as 
discussed in Need for the ETS (Section III.B. of this preamble). At the 
present time, workers are becoming seriously ill and dying as a result 
of occupational exposures to COVID-19, when a simple measure, 
vaccination, can largely prevent those deaths and illnesses. The ETS 
protects these workers through the most effective and efficient control 
available--vaccination--and further protects workers who remain 
unvaccinated through required regular testing, use of face coverings, 
and removal of all infected employees from the workplace. OSHA also 
concludes, based on its enforcement experience during the pandemic to 
date, that continued reliance on existing standards and regulations, 
the General Duty Clause of the OSH Act, 29 U.S.C. 654(a)(1), and 
workplace guidance, in lieu of an ETS, is not adequate to protect 
unvaccinated employees from the grave danger of being infected by, and 
suffering death or serious health consequences from, COVID-19.
    OSHA will continue to monitor trends in COVID-19 infections and 
death as more of the workforce and the general population become fully 
vaccinated against COVID-19 and the pandemic continues to evolve. Where 
OSHA finds a grave danger from the virus no longer exists for the 
covered workforce (or some portion thereof), or new information 
indicates a change in measures necessary to address the grave danger, 
OSHA will update this ETS, as appropriate.
    This ETS applies to employers with a total of 100 or more employees 
at any time the standard is in effect. In light of the unique 
occupational safety and health dangers presented by COVID-19, and 
against the backdrop of the uncertain economic environment of a 
pandemic, OSHA is proceeding in a stepwise fashion in addressing the 
emergency this rule covers. OSHA is confident that employers with 100 
or more employees have the administrative capacity to implement the 
standard's requirements promptly, but is less confident that smaller 
employers can do so without undue disruption. OSHA needs additional 
time to assess the capacity of smaller employers, and is seeking 
comment to help the agency make that determination. Nonetheless, the 
agency is acting to protect workers now in adopting a standard that 
will reach two-thirds of all private-sector workers in the nation, 
including those working in the largest facilities, where the most 
deadly outbreaks of COVID-19 can occur.
    The agency has also evaluated the feasibility of this ETS and has 
determined that the requirements of the ETS are both economically and 
technologically feasible, as outlined in Feasibility (Section IV. of 
this preamble). The specific requirements of the ETS are outlined and 
described in Summary and Explanation (Section VI. of this preamble).

B. Request for Comment

    Although this ETS takes effect immediately, it also serves as a 
proposal under Section 6(b) of the OSH Act (29 U.S.C. 655(b)) for a 
final standard. Accordingly, OSHA seeks comment on all aspects of this 
ETS and whether it should be adopted as a final standard. OSHA 
encourages commenters to explain why they prefer or disfavor particular 
policy choices, and include any relevant studies, experiences, 
anecdotes or other information that may help support the comment. In 
particular, OSHA seeks comments on the following topics:
    1. Employers with fewer than 100 employees. As noted above and 
fully discussed in the Summary and Explanation for Scope and 
Application (Section VI.B. of this preamble), OSHA has implemented a 
100-employee threshold for the requirements of this standard to focus 
the ETS on companies that OSHA is confident will have sufficient 
administrative systems in place to comply quickly with the ETS. The 
agency is moving in a stepwise fashion on the short timeline 
necessitated by the danger presented by COVID-19 while soliciting 
stakeholder comment and additional information to determine whether to 
adjust the scope of the ETS to address smaller employers in the future. 
OSHA seeks information about the ability of employers with fewer than 
100 employees to implement COVID-19 vaccination and/or testing 
programs. Have you instituted vaccination mandates (with or without 
alternatives), or requirements for regular COVID-19 testing or face 
covering use? What have been the benefits of your approach? What 
challenges have you had or could you foresee in implementing such 
programs? Is there anything specific to your industry, or the size of 
your business, that poses particular obstacles in implementing the 
requirements in this standard? How much time would it take, what types 
of costs would you incur, and how much would it cost for you to 
implement such requirements?
    2. Significant Risk. If OSHA were to finalize a rule based on this 
ETS, it would be a standard adopted under 6(b) of the OSH Act, which 
requires a finding of significant risk from exposure to COVID-19. As 
discussed more fully in Pertinent Legal Authority (Section II. of this 
preamble), this is a lower showing of risk than grave danger, the 
finding required to issue a 6(c) emergency temporary standard. How 
should the scope of the rule change to address the significant risk 
posed by COVID-19 in the workplace? Should portions of the rule, such 
as face coverings, apply to fully vaccinated persons?
    3. Prior COVID-19 infections. OSHA determined that workers who have 
been infected with COVID-19 but have not been fully vaccinated still 
face a grave danger from workplace exposure to SARS-CoV-2. This is an 
area of ongoing scientific inquiry. Given scientific uncertainty and 
limitations in testing for infection and immunity, OSHA is concerned 
that it would be infeasible for employers to operationalize a standard 
that would permit or require an exception from vaccination or testing 
and face covering based on prior infection with COVID-19. Is there 
additional scientific information on this topic that OSHA should 
consider as it determines whether to proceed with a permanent rule?
    In particular, what scientific criteria can be used to determine 
whether a given employee is sufficiently protected against reinfection? 
Are there any temporal limits associated with this criteria to account 
for potential reductions in immunity over time? Do you require 
employees to provide verification of infection with COVID-19? If so, 
what kinds of verification do you accept (i.e., PCR testing, antigen 
testing, etc.)? What challenges have you


experienced, if any, in operationalizing such an exception?
    4. Experience with COVID-19 vaccination policies. Should OSHA 
impose a strict vaccination mandate (i.e., all employers required to 
implement mandatory vaccination policies as defined in this ETS) with 
no alternative compliance option? OSHA seeks information on COVID-19 
vaccination policies that employers have implemented to protect 
workers. If you have implemented a COVID-19 vaccination policy:
    (a) When did you implement it, and what does your policy require? 
Was vaccination mandatory or voluntary under the policy? Do you offer 
vaccinations on site? What costs associated with vaccination did you 
cover under the policy? What percentage of your workforce was 
vaccinated as a result? Do you offer paid leave for receiving a 
vaccination? If vaccination is mandatory, have employees been resistant 
and if so what steps were required to enforce the policy?
    (b) How did you verify that employees were vaccinated? Are there 
other reliable means of vaccination verification not addressed by the 
ETS that should be included? Did you allow attestation where the 
employee could not find other proof, and if so, have you experienced 
any difficulties with this approach? Have you experienced any issues 
with falsified records of vaccination, and if so, how did you deal with 
them?
    (c) Have you experienced a decrease in infection rates or outbreaks 
after implementing this policy?
    (d) If you have received any requests for reasonable accommodation 
from vaccination, what strategies did you implement to address the 
accommodation and ensure worker safety (e.g., telework, working in 
isolation, regular testing and the use of face coverings)?
    5. COVID-19 testing and removal. OSHA seeks information on COVID-19 
testing and removal practices implemented to protect workers.
    (a) Do you have a testing and removal policy in your workplace and, 
if so, what does it require? How often do you require testing and what 
types of testing do you use (e.g., at-home tests, tests performed at 
laboratories, tests performed at your worksites)? What costs have you 
incurred as part of your testing and removal policies? Do you have 
difficulty in finding adequate availability of tests? How often? Have 
you experienced any issues with falsified test results, and if so, how 
did you deal with them? Have you experienced other difficulties in 
implementing a testing and removal scheme, including the length of time 
to obtain COVID-19 test results? Do you offer paid leave for testing?
    (b) How often have you detected and removed COVID-19 positive 
employees from the workplace under this policy? Do you provide paid 
leave and job protection to employees you remove for this reason?
    (c) Should OSHA require testing more often than on a weekly basis?
    6. Face coverings. As discussed in the Summary and Explanation for 
Face Coverings (Section VI.I. of this preamble), ASTM released a 
specification standard on February 15, 2021, to establish a national 
standard baseline for barrier face coverings (ASTM F3502-21). Should 
OSHA require the use of face coverings meeting the ASTM F3502-21 
standard instead of the face coverings specified by the ETS? If so, 
should OSHA also require that such face coverings meet the NIOSH 
Workplace Performance or Workplace Performance Plus criteria (see CDC, 
September 23, 2021)? Are there particular workplace settings in which 
face coverings meeting one standard should be favored over another? Are 
there alternative criteria OSHA should consider for face coverings 
instead of the F3502-21 standard or NIOSH Workplace Performance or 
Workplace Performance Plus criteria? Is there sufficient capacity to 
supply face coverings meeting F3502-01 and/or NIOSH Workplace 
Performance or Workplace Performance Plus criteria to all employees 
covered by the ETS? What costs have you incurred as part of supplying 
employees with face coverings meeting the appropriate criteria?
    7. Other controls. This ETS requires employees to either be fully 
vaccinated against COVID-19 or be tested weekly and wear face 
coverings, based on the type of policy their employer adopts. It stops 
short of requiring the full suite of workplace controls against SARS-
CoV-2 transmission recommended by OSHA and the CDC, including 
distancing, barriers, ventilation, and sanitation. As OSHA explained in 
Need for the ETS (Section III.B. of this preamble), OSHA has determined 
that it needs more information before imposing these requirements on 
the entire scope of industries and employers covered by the standard. 
OSHA is interested in hearing from employers about their experience in 
implementing a full suite of workplace controls against COVID-19.
    What measures have you taken to protect employees against COVID-19 
in your workplace? Are there controls that you attempted to employ but 
found ineffective or infeasible? What are they? Why did you conclude 
that they were they ineffective or infeasible; for example, are there 
particular aspects of your workplace or industry that make certain 
controls infeasible? Do you require both fully vaccinated and 
unvaccinated employees to comply with these controls? Have you 
experienced a reduction in infection rates or outbreaks since 
implementing these controls?
    8. Educational materials. Have you implemented any policies or 
provided any information that has been helpful in encouraging an 
employee to be vaccinated?
    9. Feasibility and health impacts. Do you have any experience or 
data that would inform OSHA's estimates in its economic feasibility 
analysis or any of the assumptions or estimates used in OSHA's 
identification of the number of hospitalizations prevented and lives 
saved from its health impacts analysis (see OSHA, October 2021c)?

II. Pertinent Legal Authority

    The purpose of the Occupational Safety and Health Act of 1970 (OSH 
Act), 29 U.S.C. 651 et seq., is ``to assure so far as possible every 
working man and woman in the Nation safe and healthful working 
conditions and to preserve our human resources.'' 29 U.S.C. 651(b). To 
this end, Congress authorized the Secretary of Labor (Secretary) to 
promulgate and enforce occupational safety and health standards under 
sections 6(b) and (c) of the OSH Act.\1\ 29 U.S.C. 655(b). These 
provisions provide bases for issuing occupational safety and health 
standards under the Act. Once OSHA has established as a threshold 
matter that a health standard is necessary under section 6(b) or (c)--
i.e., to reduce


a significant risk of material health impairment, or a grave danger to 
employee health--the Act gives the Secretary ``almost unlimited 
discretion to devise means to achieve the congressionally mandated 
goal'' of protecting employee health, subject to the constraints of 
feasibility. See United Steelworkers of Am. v. Marshall, 647 F.2d 1189, 
1230 (D.C. Cir. 1981). A standard's individual requirements need only 
be ``reasonably related'' to the purpose of ensuring a safe and 
healthful working environment. Id. at 1237, 1241; see also Forging 
Indus. Ass'n v. Sec'y of Labor, 773 F.2d 1436, 1447 (4th Cir. 1985). 
OSHA's authority to regulate employers is hedged by constitutional 
considerations and, pursuant to section 4(b)(1) of the OSH Act, the 
regulations and enforcement policies of other federal agencies. See, 
e.g., Chao v. Mallard Bay Drilling, Inc., 534 U.S. 235, 241 (2002).

Act to the Assistant Secretary of Labor for Occupational Safety and

This section uses the terms Secretary and OSHA interchangeably.

    The OSH Act in section 6(c)(1) states that the Secretary ``shall'' 
issue an emergency temporary standard (ETS) upon a finding that the ETS 
is necessary to address a grave danger to workers. See 29 U.S.C. 
655(c). In particular, the Secretary shall provide, without regard to 
the requirements of chapter 5, title 5, United States Code, for an 
emergency temporary standard to take immediate effect upon publication 
in the Federal Register if the Secretary makes two determinations: That 
employees are exposed to grave danger from exposure to substances or 
agents determined to be toxic or physically harmful or from new 
hazards, and that such emergency standard is necessary to protect 
employees from such danger. 29 U.S.C. 655(c)(1). A separate section of 
the OSH Act, section 8(c), authorizes the Secretary to prescribe 
regulations requiring employers to make, keep, and preserve records 
that are necessary or appropriate for the enforcement of the Act. 29 
U.S.C. 657(c)(1). Section 8(c) also provides that the Secretary shall 
require employers to keep records of, and report, work-related deaths 
and illnesses. 29 U.S.C. 657(c)(2).
    The ETS provision, section 6(c)(1), exempts the Secretary from 
procedural requirements contained in the OSH Act and the Administrative 
Procedure Act, including those for public notice, comments, and a 
rulemaking hearing. See, e.g., 29 U.S.C. 655(b)(3); 5 U.S.C. 552, 553.
    The Secretary must issue an ETS in situations where employees are 
exposed to a ``grave danger'' and immediate action is necessary to 
protect those employees from such danger. 29 U.S.C. 655(c)(1); Pub. 
Citizen Health Research Grp. v. Auchter, 702 F.2d 1150, 1156 (D.C. Cir. 
1983). The determination of what exact level of risk constitutes a 
``grave danger'' is a ``policy consideration that belongs, in the first 
instance, to the Agency.'' Asbestos Info. Ass'n, 727 F.2d at 425 
(accepting OSHA's determination that eighty lives at risk over six 
months was a grave danger); Indus. Union Dep't, AFL-CIO v. Am. 
Petroleum Inst., 448 U.S. 607, 655 n.62 (1980). However, a ``grave 
danger'' represents a risk greater than the ``significant risk'' that 
OSHA must show in order to promulgate a permanent standard under 
section 6(b) of the OSH Act, 29 U.S.C. 655(b). Int'l Union, United 
Auto., Aerospace, & Agr. Implement Workers of Am., UAW v. Donovan, 590 
F. Supp. 747, 755-56 (D.D.C. 1984), adopted, 756 F.2d 162 (D.C. Cir. 
1985); see also Indus. Union Dep't, AFL-CIO, 448 U.S. at 640 n.45 
(noting the distinction between the standard for risk findings in 
permanent standards and ETSs).
    In determining the type of health effects that may constitute a 
``grave danger'' under the OSH Act, the Fifth Circuit emphasized ``the 
danger of incurable, permanent, or fatal consequences to workers, as 
opposed to easily curable and fleeting effects on their health.'' Fla. 
Peach Growers Ass'n, Inc. v. U. S. Dep't of Labor, 489 F.2d 120, 132 
(5th Cir. 1974). Although the findings of grave danger and necessity 
must be based on evidence of ``actual, prevailing industrial 
conditions,'' see Int'l Union, 590 F. Supp. at 751, when OSHA 
determines that exposure to a particular hazard would pose a grave 
danger to workers, OSHA can assume an exposure to a grave danger 
wherever that hazard is present in a workplace. Dry Color Mfrs. Ass'n, 
Inc. v. Dep't of Labor, 486 F.2d 98, 102 n.3 (3d Cir. 1973).
    In demonstrating whether OSHA had shown that an ETS is necessary, 
the Fifth Circuit considered whether OSHA had another available means 
of addressing the risk that would not require an ETS. Asbestos Info. 
Ass'n, 727 F.2d at 426 (holding that necessity had not been proven 
where OSHA could have increased enforcement of already-existing 
standards to address the grave risk to workers from asbestos exposure). 
Additionally, a standard must be both economically and technologically 
feasible in order to be ``reasonably necessary and appropriate'' under 
section 3(8) and, by inference, ``necessary'' under section 6(c)(1)(B) 
of the Act. Cf. Am. Textile Mfrs. Inst., Inc. v. Donovan, 452 U.S. 490, 
513 n.31 (1981) (noting ``any standard that was not economically or 
technologically feasible would a fortiori not be `reasonably necessary 
or appropriate' '' as required by the OSH Act's definition of 
``occupational safety and health standard'' in section 3(8)); see also 
Florida Peach Growers, 489 F.2d at 130 (recognizing that the 
promulgation of any standard, including an ETS, must account for its 
economic effect). However, given that section 6(c) is aimed at enabling 
OSHA to protect workers in emergency situations, the agency is not 
required to make a feasibility showing with the same rigor as in 
ordinary section 6(b) rulemaking. Asbestos Info. Ass'n, 727 F.2d at 424 
n.18.
    On judicial review of an ETS, OSHA is entitled to great deference 
on the determinations of grave danger and necessity required under 
section 6(c)(1). See, e.g., Pub. Citizen Health Research Grp., 702 F.2d 
at 1156; Asbestos Info. Ass'n, 727 F.2d at 422 (judicial review of 
these legislative determinations requires deference to the agency); cf. 
Am. Dental Ass'n v. Martin, 984 F.2d 823, 831 (7th Cir. 1993) (``the 
duty of a reviewing court of generalist judges is merely to patrol the 
boundary of reasonableness''). These determinations are ``essentially 
legislative and rooted in inferences from complex scientific and 
factual data.'' Pub. Citizen Health Research Grp., 702 F.2d at 1156. 
The agency is not required to support its conclusions ``with anything 
approaching scientific certainty,'' Indus. Union Dep't, AFL-CIO, 448 
U.S. at 656, and has the ``prerogative to choose between conflicting 
evidence.'' Asbestos Info. Ass'n, 727 F.2d at 425.
    The determinations of the Secretary in issuing standards under 
section 6 of the OSH Act, including ETSs, must be affirmed if supported 
by ``substantial evidence in the record considered as a whole.'' 29 
U.S.C. 655(f). The Supreme Court described substantial evidence as 
``such relevant evidence as a reasonable mind might accept as adequate 
to support a conclusion.'' Am. Textile Mfrs. Inst., 452 U.S. at 522-23 
(quoting Universal Camera Corp. v. NLRB, 340 U.S. 474, 477 (1951)). The 
Court also noted that ``the possibility of drawing two inconsistent 
conclusions from the evidence does not prevent an administrative 
agency's finding from being supported by substantial evidence.'' Id. at 
523 (quoting Consolo v. FMC, 383 U.S. 607, 620 (1966)). The Fifth 
Circuit, recognizing the size and complexity of the rulemaking record 
before it in the case of OSHA's ETS for organophosphorus pesticides, 
stated that a court's function in reviewing an ETS to determine whether 
it meets the substantial evidence standard is ``basically [to] 
determine whether the


Secretary carried out his essentially legislative task in a manner 
reasonable under the state of the record before him.'' Fla Peach 
Growers Ass'n, 489 F.2d at 129.
    Although Congress waived the ordinary rulemaking procedures in the 
interest of ``permitting rapid action to meet emergencies,'' section 
6(e) of the OSH Act, 29 U.S.C. 655(e), requires OSHA to include a 
statement of reasons for its action when it issues any standard. Dry 
Color Mfrs., 486 F.2d at 105-06 (finding OSHA's statement of reasons 
inadequate). By requiring the agency to articulate its reasons for 
issuing an ETS, the requirement acts as ``an essential safeguard to 
emergency temporary standard-setting.'' Id. at 106. However, the Third 
Circuit noted that it did not require justification of ``every 
substance, type of use or production technique,'' but rather a 
``general explanation'' of why the standard is necessary. Id. at 107.
    ETSs are, by design, temporary in nature. Under section 6(c)(3), an 
ETS serves as a proposal for a permanent standard in accordance with 
section 6(b) of the OSH Act (permanent standards), and the Act calls 
for the permanent standard to be finalized within six months after 
publication of the ETS. 29 U.S.C. 655(c)(3); see Fla. Peach Growers 
Ass'n, 489 F.2d at 124. The ETS is effective ``until superseded by a 
standard promulgated in accordance with'' section 6(c)(3). 29 U.S.C. 
655(c)(2).
    Section 6(c)(1) states that the Secretary ``shall'' provide for an 
ETS when OSHA makes the prerequisite findings of grave danger and 
necessity. See Pub. Citizen Health Research Grp., 702 F.2d at 1156 
(noting the mandatory language of section 6(c)). OSHA is entitled to 
great deference in its determinations, and it must also account for 
``the fact that `the interests at stake are not merely economic 
interests in a license or a rate structure, but personal interests in 
life and health.' '' Id. (quoting Wellford v. Ruckelshaus, 439 F.2d 
598, 601 (D.C. Cir. 1971)).
    When OSHA issues a standard pursuant to section 6--whether 
permanent or an ETS--section 18 of the OSH Act provides that OSHA's 
standard preempts any state occupational safety or health standard 
``relating to [the same] occupational safety or health issue'' as the 
Federal standard. 29 U.S.C. 667(b); see also Gade v. Nat'l Solid Wastes 
Mgmt. Ass'n, 505 U.S. 88, 97 (1992). A state can avoid preemption only 
if it submits, and receives Federal approval for, a state plan for the 
development and enforcement of standards pursuant to section 18 of the 
Act, which must be ``at least as effective'' as the Federal standards. 
29 U.S.C. 667; Indus. Truck Ass'n v. Henry, 125 F.3d 1305, 1311 (9th 
Cir. 1997). However, the OSH Act does not preempt state laws of 
``general applicability'' that regulate workers and non-workers alike, 
so long as they do not conflict with an OSHA standard. Gade, 505 U.S. 
at 107.
    As discussed in detail elsewhere in this preamble, OSHA has 
determined that a grave danger exists necessitating a new ETS (see 
Grave Danger and Need for the ETS, Sections III.A. and III.B. of this 
preamble), and that compliance with this ETS is feasible for covered 
employers (see Feasibility, Section IV. of this preamble). OSHA has 
also provided a more detailed explanation of each provision of this ETS 
in Summary and Explanation (Section VI. of this preamble). In addition, 
OSHA wishes to provide here some general guidance on its legal 
authority to regulate COVID-19 hazards, and for particular provisions 
of this ETS.
    As a threshold matter, OSHA's authority to regulate workplace 
exposure to biological hazards like SARS-CoV-2 is well-established. 
Section 6(b)(5) of the OSH Act uses similar language to section 
6(c)(1)(A): The former sets forth requirements for promulgating 
permanent standards addressing ``toxic materials or harmful physical 
agents,'' and the latter authorizes OSHA to promulgate an ETS 
addressing ``substances or agents determined to be toxic or physically 
harmful'' (as well as ``new hazards''). OSHA has consistently 
identified biological hazards similar to SARS-CoV-2, as well as SARS-
CoV-2 itself, to be ``toxic materials or harmful physical agents'' 
under the Act. Indeed, in its exposure and medical records access 
regulation, OSHA has defined ``toxic materials or harmful physical 
agents'' to include ``any . . . biological agent (bacteria, virus, 
fungus, etc.)'' for which there is evidence that it poses a chronic or 
acute health hazard. 29 CFR 1910.1020(c)(13). And in addition to 
previously regulating exposure to SARS-CoV-2 as a new and physically 
harmful agent in the Healthcare ETS (see, e.g., 86 FR at 32381), OSHA 
has also previously regulated biological hazards like SARS-CoV-2 as 
health hazards under section 6(b)(5), for example in the Bloodborne 
Pathogens (BBP) standard, 29 CFR 1910.1030, which addresses workplace 
exposure to HIV and Hepatitis B. The BBP standard was upheld (except as 
to application in certain limited industries) in American Dental 
Association, which observed that ``the infectious character'' of the 
regulated bloodborne diseases might warrant ``more regulation than 
would be necessary in the case of a noncommunicable disease.'' 984 F.2d 
at 826. In addition, in the preamble to the respiratory protection 
standard, 29 CFR 1910.134, which was also promulgated under section 
6(b)(5), ``OSHA emphasize[d] that [the] respiratory protection standard 
does apply to biological hazards.'' Respiratory Protection, 63 FR 1152-
01, 1180 (Jan. 8, 1998) (citing Mahone Grain Corp., 10 BNA OSHC 1275 
(No. 77-3041, 1981)).
    In addition to being a physically harmful agent covered by section 
6(c)(1)(A), SARS-CoV-2 is also, without question, a ``new hazard'' 
covered by this provision, as discussed in more detail in Grave Danger 
(Section III.A. of this preamble). SARS-CoV-2 was not known to exist 
until January 2020, and since then more than 725,000 people have died 
from COVID-19 in the U.S. alone (CDC, October 18, 2021--Cumulative US 
Deaths).
    Turning to specific provisions of this standard, the vaccination 
requirements in this ETS are also well within the bounds of OSHA's 
authority. Vaccination can be a critical tool in the pursuit of health 
and safety goals, particularly in response to an infectious and highly 
communicable disease. See, e.g., Jacobson v. Commonwealth of Mass., 197 
U.S. 11, 27-28 (1905) (recognizing use of smallpox vaccine as a 
reasonable measure to protect public health and safety); Klaassen v. 
Trustees of Ind. Univ., 7 F.4th 592, 593 (7th Cir. 2021) (citing 
Jacobson and noting that vaccination may be an appropriate safety 
measure against SARS-CoV-2 as ``[v]accination protects not only the 
vaccinated persons but also those who come in contact with them''). And 
the OSH Act itself explicitly acknowledges that such treatments might 
be necessary, in some circumstances. 29 U.S.C. 669(a)(5) (providing in 
the Act's provisions on research and related activities conducted by 
the Secretary of Health and Human Services to aid OSHA in its 
formulation of health and safety standards that ``[n]othing in this or 
any other provision of this Act shall be deemed to authorize or require 
medical examination, immunization, or treatment for those who object 
thereto on religious grounds, except where such is necessary for the 
protection of the health or safety of others.'' (emphasis added)). In 
recognition of the health and safety benefits provided by vaccination, 
OSHA has previously exercised its authority to promulgate vaccine-
related requirements in the COVID-19 Healthcare ETS (29 CFR 
1910.502(m))


and the BBP standard (29 CFR 1910.1030(f)). The BBP standard 
illustrates congressional understanding that the statutory delegation 
of authority to OSHA to issue standards includes authority for vaccine 
provisions, where appropriate. See Public Law 102-170, Title I, Section 
100, 105 Stat. 1107 (1991) (directing OSHA to complete the BBP 
rulemaking by a date certain, and providing that if OSHA did not do so, 
the proposed rule, which included a vaccine provision, would become the 
final standard).
    Additionally, OSHA's authority to require employers to bear the 
costs of particular provisions of a standard is solidly grounded in the 
OSH Act. The Act reflects Congress's determination that the costs of 
compliance with the Act and OSHA standards are part of the cost of 
doing business and OSHA may foreclose employers from shifting those 
costs to employees. See Am. Textile Mfrs. Inst., 452 U.S. at 514; 
Phelps Dodge Corp. v. OSHRC, 725 F.2d 1237, 1239-40 (9th Cir. 1984); 
see also Sec'y of Labor v. Beverly Healthcare-Hillview, 541 F.3d 193 
(3d Cir. 2008). Consistent with this authority, OSHA has largely 
required employers to bear the costs of the provisions of this ETS, 
including the typical costs associated with vaccination. The allocation 
of vaccination costs to employers in this ETS is similar to OSHA's 
treatment of vaccine-related costs in the COVID-19 Healthcare ETS and 
the BBP standards. See 29 CFR 1910.502(m), (p); 29 CFR 
1910.1030(f)(1)(ii)(A).
    The OSH Act provides OSHA with discretion, however, to decide 
whether to impose certain costs--such as those related to medical 
examinations or other tests--on employers ``[w]here [it determines that 
such costs are] appropriate.'' 29 U.S.C. 655(b)(7). OSHA has determined 
that for purposes of this ETS, it would not be ``appropriate'' to 
impose on employers any costs associated with COVID-19 testing for 
employees who choose not to be vaccinated. For most of the agency's 
existing standards containing medical testing and removal provisions, 
OSHA has found it necessary to impose the costs of such provisions on 
employers in order to remove barriers to employee participation in 
medical examinations that are critical to effectuating the standards' 
safety and health protections. See United Steelworkers of Am., 647 F.2d 
at 1229-31, 1237-38. However, as explained in greater detail elsewhere 
in this preamble (see Need for the ETS, Section III.B. of this 
preamble), the ETS's safety and health protections are best effectuated 
by employee vaccination, not testing. Accordingly, OSHA only requires 
employers to bear the costs of employee compliance with the preferred, 
and more protective, vaccination provision, but not costs associated 
with testing. The agency does not believe it appropriate to impose the 
costs of testing on an employer where an employee has made an 
individual choice to pursue a less protective option. For the same 
reasons, OSHA has also determined that it is not appropriate to require 
employers to pay for face coverings for employees who choose not to be 
vaccinated.\2\
---------------------------------------------------------------------------

    \2\ OSHA notes that while the ETS does not impose these testing 
or face covering costs on employers, in some circumstances employers 
may be required to pay for the costs related to testing and/or face 
coverings by other laws, regulations, or collectively negotiated 
agreements. OSHA has no authority under the OSH Act to determine 
whether such obligations under other laws, regulations, or 
agreements might exist.
---------------------------------------------------------------------------

    Finally, the Act and its legislative history ``both demonstrate 
unmistakably'' OSHA's authority to require employers to temporarily 
remove workers from the workplace to prevent exposure to a health 
hazard. United Steelworkers of Am., 647 F.2d at 1230. And again, this 
is an authority OSHA has repeatedly exercised in prior standards, 
including in: COVID-19 Healthcare ETS (29 CFR 1910.502); Lead (29 CFR 
1910.1025); Cadmium (29 CFR 1910.1027); Benzene (29 CFR 1910.1028); 
Formaldehyde (29 CFR 1910.1048); Methylenedianiline (29 CFR 1910.1050); 
Methylene Chloride (29 CFR 1910.1052); and Beryllium (29 CFR 
1910.1024). It is equally appropriate to impose that obligation here.
    For all of these reasons, as well as those explained more fully in 
other areas of this preamble, OSHA has the authority--and obligation--
to promulgate this ETS.

III. Rationale for the ETS

A. Grave Danger

I. Introduction
    Section 6(c)(1) of the OSH Act requires the Secretary to issue an 
ETS in situations where employees are exposed to a ``grave danger'' and 
immediate action is necessary to protect those employees from such 
danger (29 U.S.C. 655(c)(1)). Consistent with its legal duties, OSHA is 
issuing this ETS to address the grave danger posed by occupational 
exposure to SARS-CoV-2, the virus that causes COVID-19.\3\ OSHA has 
determined that occupational exposure to SARS-CoV-2, including the 
Delta variant (B.1.617.2 and AY lineages), presents a grave danger to 
unvaccinated workers in the U.S., with several exceptions explained 
below.\4\ This finding of grave danger is based on the science of how 
the virus spreads, the transmissibility of the disease in workplaces, 
and the serious adverse health effects, including death, that can be 
suffered by those who are diagnosed with COVID-19. The protections of 
this ETS--which will apply, with some limitations, to a broad range of 
workplace settings where exposure to SARS-CoV-2 may occur--are designed 
to protect employees from infection with SARS-CoV-2 and from the dire, 
sometimes fatal, consequences of such infection.
---------------------------------------------------------------------------

    \3\ OSHA is defining the grave danger as workplace exposure to 
SARS-CoV-2, the virus that causes the development of COVID-19. 
COVID-19 is the disease that can occur in people exposed to SARS-
CoV-2, and that leads to the health effects described in this 
section. This distinction applies despite OSHA's use of the terms 
SARS-CoV-2 and COVID-19 interchangeably in some parts of this 
preamble.
    \4\ OSHA refers to the grave danger from occupational exposure 
to SARS-CoV-2 throughout this document. Those references are 
intended to encompass exposure to SARS-CoV-2 and all variants of 
SARS-CoV-2, including the Delta variant.
---------------------------------------------------------------------------

    The fact that COVID-19 is not a uniquely work-related hazard does 
not change the determination that it is a grave danger to which 
employees are exposed, nor does it excuse employers from their duty to 
protect employees from the occupational transmission of SARS-CoV-2. The 
OSH Act is intended to ``assure so far as possible every working man 
and woman in the Nation safe and healthful working conditions'' (29 
U.S.C. 651(b)), and there is nothing in the Act to suggest that its 
protections do not extend to hazards which might occur outside of the 
workplace as well as within. Indeed, COVID-19 is not the first hazard 
that OSHA has regulated that occurs both inside and outside the 
workplace. For example, the hazard of noise is not unique to the 
workplace, but the Fourth Circuit has upheld OSHA's Occupational Noise 
Exposure standard (29 CFR 1910.95) (Forging Industry Ass'n v. Sec' of 
Labor, 773 F.2d 1437, 1444 (4th Cir. 1985)). Diseases caused by 
bloodborne pathogens, including HIV/AIDS and hepatitis B, are also not 
unique to the workplace, but the Seventh Circuit upheld the majority of 
OSHA's Bloodborne Pathogens standard (29 CFR 1910.1030) (Am. Dental 
Ass'n v. Martin, 984 F.2d 823 (7th Cir. 1993)). OSHA's Sanitation


standard, 29 CFR 1910.141, which requires measures such as cleaning, 
waste disposal, potable water, toilets, and washing facilities, 
addresses hazards that exist everywhere--both within and outside of 
workplaces. Moreover, employees have more freedom to control their 
environment outside of work, and to make decisions about their behavior 
and their contact with others to better minimize their risk of 
exposure. However, during the workday, while under the control of their 
employer, workers may have little ability to limit contact with 
coworkers, clients, members of the public, patients, and others, any 
one of whom could represent a source of exposure to SARS-CoV-2. OSHA 
has a mandate to protect employees from hazards they are exposed to at 
work, even if they may be exposed to similar hazards outside of work.
    As described above in Pertinent Legal Authority (Section II. of 
this preamble), ``grave danger'' indicates a risk that is more than 
``significant'' (Int'l Union, United Auto., Aerospace, & Agr. Implement 
Workers of Am., UAW v. Donovan, 590 F. Supp. 747, 755-56 (D.D.C. 1984); 
Indus. Union Dep't, AFL-CIO v. Am. Petroleum Inst., 448 U.S. 607, 640 
n.45, 655 (1980) (stating that a rate of 1 worker in 1,000 workers 
suffering a given health effect constitutes a ``significant'' risk)). 
``Grave danger,'' according to one court, refers to ``the danger of 
incurable, permanent, or fatal consequences to workers, as opposed to 
easily curable and fleeting effects on their health'' (Fla. Peach 
Growers Ass'n, Inc. v. U.S. Dep't of Labor, 489 F.2d 120, 132 (5th Cir. 
1974)). Fleeting effects were described as nausea, excessive 
salivation, perspiration, or blurred vision and were considered so 
minor that they often went unreported; these effects are in stark 
contrast with the adverse health effects of COVID-19 infections, which 
are formally referenced as ranging from ``mild'' to ``critical,'' \5\ 
but which can involve significant illness, hospital stays, ICU care, 
death, and long-term health complications for survivors. Beyond this, 
however, ``the determination of what constitutes a risk worthy of 
Agency action is a policy consideration that belongs, in the first 
instance, to the Agency'' (Asbestos Info. Ass'n/N. Am. v. OSHA, 727 
F.2d 415, 425 (5th Cir. 1984)).
---------------------------------------------------------------------------

    \5\ See the definitions for the different levels of severity of 
COVID-19 illness in the National Institutes of Health's COVID-19 
treatment guidelines (NIH, October 12, 2021).
---------------------------------------------------------------------------

    In the context of ordinary 6(b) rulemaking, the Supreme Court has 
said that the OSH Act is not a ``mathematical straitjacket,'' nor does 
it require the agency to support its findings ``with anything 
approaching scientific certainty,'' particularly when operating on the 
``frontiers of scientific knowledge'' (Indus. Union Dep't, AFL-CIO v. 
Am. Petroleum Inst., 448 U.S. 607, 655-56 (1980)). Courts reviewing 
OSHA's determination of grave danger do so with ``great deference'' 
(Pub. Citizen Health Research Grp. v. Auchter, 702 F.2d 1150, 1156 
(D.C. Cir. 1983)). In one case, the Fifth Circuit, in reviewing an OSHA 
ETS for asbestos, declined to question the agency's finding that 80 
worker lives at risk nationwide over six months constituted a grave 
danger (Asbestos Info. Ass'n/N. Am., 727 F.2d at 424). OSHA estimates 
that this ETS would save over 6,500 worker lives and prevent over 
250,000 hospitalizations over the course of the next six months (OSHA, 
October 2021c). Here, the mortality and morbidity risk to employees 
from COVID-19 is so dire that the grave danger from exposures to SARS-
CoV-2 is clear.
    SARS-CoV-2 is both a physically harmful agent and a new hazard (see 
29 U.S.C. 655(c)(1)(A)). The majority of OSHA's previous ETSs addressed 
toxic substances that had been familiar to the agency for many years 
prior to issuance of the ETS. OSHA's Healthcare ETS, issued in response 
to COVID-19 earlier this year, is one notable exception. In most cases, 
OSHA's ETSs were issued in response to new information about substances 
that had been used in workplaces for decades (e.g., Vinyl Chloride (39 
FR 12342 (April 5, 1974)); Benzene (42 FR 22516 (May 3, 1977)); 1,2-
Dibromo-3-chloropropane (42 FR 45536 (Sept. 9, 1977))). In some cases, 
the hazards of the toxic substance were already so well established 
that OSHA promulgated an ETS simply to update an existing standard 
(e.g., Vinyl cyanide (43 FR 2586 (Jan. 17, 1978))). The COVID-19 
Healthcare ETS, which was issued in June 2021, was the sole instance in 
which OSHA issued an ETS to address a grave danger from a substance 
that had only recently come into existence. Although that action by the 
agency was challenged, the case has not gone to briefing (see United 
Food & Commercial Workers Int'l Union, AFL-CIO, CLC and AFL-CIO v. 
OSHA, Dep't of Labor, D.C. Circuit No. 21-1143). Thus, no court has had 
occasion to examine OSHA's authority under section (6)(c) of the OSH 
Act (29 U.S.C. 655(c)) to address a grave danger from a ``new hazard.'' 
Yet by any measure, SARS-CoV-2 is a new hazard. Unlike any of the 
hazards addressed in previous ETSs, there were no documented cases of 
SARS-CoV-2 infections in the United States until January 2020. Since 
then, more than 725,000 people have died in the U.S. alone (CDC, 
October 18, 2021--Cumulative US Deaths). The pandemic continues to 
affect workers and workplaces, with workplace exposures leading to 
further exposures among workers' families and communities. Clearly, 
SARS-CoV-2 is both a physically harmful agent and a new hazard that 
presents a grave danger to workers in the U.S.
    Published on June 21, 2021, OSHA's Healthcare ETS (86 FR 32376) was 
written in response to the grave danger posed to healthcare workers in 
the United States who faced a heightened risk of infection from COVID-
19. In the healthcare ETS, OSHA described its finding of grave danger 
for healthcare and healthcare support service workers (see 86 FR 32381-
32412). OSHA now finds that all unvaccinated workers, with some 
exceptions, face a grave danger from the SARS-CoV-2 virus.\6\
---------------------------------------------------------------------------

    \6\ When OSHA refers to ``unvaccinated'' individuals in its 
grave danger finding, it means all individuals who are not fully 
vaccinated against COVID-19, i.e., those who are completely 
unvaccinated and those who are partially vaccinated.
---------------------------------------------------------------------------

II. Nature of the Disease
    The health effects of symptomatic COVID-19 illness can range from 
mild disease consisting of fever or chills, cough, and shortness of 
breath to severe disease. Severe cases can involve respiratory failure, 
blood clots, long-term cardiovascular and neurological effects, and 
organ damage, which can lead to hospitalization, ICU admission, and 
death (see 86 FR 32383-32388; NINDS, September 2, 2021). Even in the 
short time since the Healthcare ETS's publication in June 2021, the 
risk posed by COVID-19 has changed meaningfully. Since OSHA considered 
the impact of COVID-19 when promulgating the Healthcare ETS, over 
135,000 additional Americans have died from COVID-19, and over 933,000 
have been hospitalized, (CDC, October 18, 2021--Cumulative US Deaths; 
CDC, May 28, 2021; CDC, October 18, 2021--Weekly Review). In August 
2021, COVID-19 was the third leading cause of death in the United 
States, trailing only heart disease and cancer (Ortaliza et al., August 
27, 2021). By September 20, 2021, COVID-19 had killed as many Americans 
as the 1918-1919 flu pandemic (Johnson, September 20, 2021).
    While the Healthcare ETS addresses the risk of illness and death 
from


COVID-19 as the SARS-CoV-2 virus continues to change over time, it does 
not specifically address the increases in infectiousness and 
transmission, and the potentially more severe health effects, related 
to the Delta variant. The rapid rise to predominance of the Delta 
variant in the U.S. occurred shortly after the ETS was published. At 
this time, the widespread prevalence of the Delta variant and its 
increased transmissibility have resulted in increased risk of exposure 
and disease relative to the previously-dominant strains of the SARS-
CoV-2 virus. Adding to the information covered in the Healthcare ETS, 
the following sections provide a brief review of SARS-CoV-2 and 
describe the characteristics of the Delta variant that are different 
from previous versions of SARS-CoV-2 and have changed the risks posed 
by COVID-19. The agency specifically references the material presented 
in the Healthcare ETS, which is still relevant to this analysis, to 
support OSHA's finding of grave danger. Taken together, the information 
available to OSHA demonstrates that SARS-CoV-2 poses a grave danger to 
unvaccinated workers across all industry sectors.
a. Variants of SARS-CoV-2
    Viral mutations have been a serious concern of scientists, public 
health experts, and policymakers from the beginning of the COVID-19 
pandemic. Viral mutations can affect how a virus interacts with a 
cell--altering the virus's transmissibility, infection severity, and 
sensitivity to vaccines. The U.S. government's SARS-CoV-2 Interagency 
Group has a variant classification scheme that defines four classes of 
SARS-CoV-2 variants: Variants Being Monitored (VBM), Variants of 
Interest (VOI), Variants of Concern (VOC), and Variants of High 
Consequence (VOHC). These variant designations are based on their 
``proportions at the national and regional levels and the potential or 
known impact of the constellation of mutations on the effectiveness of 
medical countermeasures, severity of disease, and ability to spread 
from person to person'' (CDC, October 4, 2021), with VOIs considered 
less serious than VOCs and VOCs considered less serious than VOHCs. As 
of early October 2021, the CDC was monitoring 10 VBMs--Alpha (B.1.1.7, 
Q.1-Q.8), Beta (B.1.351, B.1.351.2, B.1.351.3), Gamma (P.1, P.1.1, 
P.1.2), Epsilon (B.1.427 and B.1.429), Eta (B.1.525), Iota (B.1.526), 
Kappa (B.1.617.1), B.1.617.3, Mu (B.1.621, B.1.621.1), and Zeta (P.2)--
and one VOC--Delta (B.1.617.2 and AY.1 sublineages)--in the U.S. (CDC, 
October 4, 2021). CDC defines a VOC as ``[a] variant for which there is 
evidence of an increase in transmissibility, more severe disease (e.g., 
increased hospitalizations or deaths), significant reduction in 
neutralization by antibodies generated during previous infection or 
vaccination, reduced effectiveness of treatments or vaccines, or 
diagnostic detection failures'' (CDC, October 4, 2021).
    While the proportions of SARS-CoV-2 variants in the United States 
have shifted over time (CDC, May 24, 2021c; CDC, October 18, 2021--
Variant Proportions, July through October 2021), the primary variant 
that drove COVID-19 transmission in the late Winter and Spring of 2021 
was the Alpha variant. The CDC noted that Alpha is associated with an 
increase in transmission, as well as potentially increased incidences 
of hospitalization and death, compared to the predominant variants 
before its emergence (CDC, October 4, 2021; Pascall et al., August 24, 
2021; Julin et al., September 22, 2021). As Alpha transmission subsided 
in the United States during the late Spring and early Summer of 2021, 
Delta emerged and quickly became the predominant variant in the U.S. by 
July 3, 2021 (CDC, October 18, 2021--Variant Proportions, July through 
October 2021). Delta now accounts for more than 99% of circulating 
virus nationwide (CDC, October 18, 2021--Variant Proportions, July 
through October 2021).
    FDA authorized and approved COVID-19 vaccines currently work well 
against all of these variants; however, there are differences in 
various variants' ability to spread and the likelihood of infection to 
cause severe illness. Data on the Beta and Gamma variants do not 
indicate that infections from these variants caused more severe illness 
or death than other VOCs. Data on the Alpha variant does indicate its 
ability to cause more severe illness and death in infected individuals. 
And some data on the Delta variant suggests that the Delta variant may 
cause more severe illness than previous variants, including Alpha, in 
unvaccinated individuals (CDC, October 4, 2021).
    The emergence of the Delta variant, along with other VOCs, has 
resulted in a more deadly pandemic (Fisman and Tuite, July 12, 2021). 
While the Delta variant is the most transmissible SARS-CoV-2 variant to 
date, the possibility remains for the rise of future VOCs, and even 
more dangerous VOHCs, as the virus continues to spread and mutate. 
Inadequate vaccination rates and the abundance of transmission create 
an environment that can foster the development of new variants that 
could be similarly, or even more, disruptive (Liu and Rocklov, August, 
4, 2021). In this context, it is critical that OSHA address the grave 
danger from COVID-19 that unvaccinated workers are currently facing by 
requiring vaccination and the other measures included in this rule, in 
order to significantly slow the transmission of COVID-19 in workers and 
workplaces and mitigate the rise of future variants.
b. Transmission
    SARS-CoV-2 is a highly transmissible virus, regardless of variant. 
Since the first case was detected in the U.S., there have been close to 
45 million reported cases of COVID-19, affecting every state and 
territory, with thousands more infected each day (CDC, October 18, 
2021--Cumulative US Cases), and some indication that these numbers 
continue to underestimate the full burden of disease (CDC, July 27, 
2021). According to the CDC, the primary way the SARS-CoV-2 virus 
spreads from an infected person to others is through the respiratory 
droplets that are produced when an infected person coughs, sneezes, 
sings, talks, or breathes (CDC, May 7, 2021). Infection could then 
occur when another person breathes in the virus. Most commonly this 
occurs when people are in close contact with one another in indoor 
spaces (within approximately six feet for at least fifteen minutes) 
(CDC, August 13, 2021). Additionally, airborne transmission may occur 
in indoor spaces without adequate ventilation where small respiratory 
particles are able to remain suspended in the air and accumulate (CDC, 
May 7, 2021; Fennelly, July 24, 2020). While scientists' understanding 
of the Delta variant's virology is evolving and remains at the frontier 
of science, current data shows that the routes of transmission remain 
the same for all currently-identified SARS-CoV-2 variants. In addition, 
all variants can be transmitted by people who are pre-symptomatic 
(i.e., people who are infected but do not yet feel sick) or 
asymptomatic (i.e., people who are infected but never feel any symptoms 
of COVID-19), as well as those who are symptomatic. Pre-symptomatic and 
asymptomatic transmission continue to pose serious challenges to 
containing the spread of COVID-19. For more extensive information on 
transmission routes, as well as pre-symptomatic and asymptomatic 
transmission, see the preamble to the Healthcare ETS (86 FR


32392-32396), which is hereby included in the record of this ETS.\7\
---------------------------------------------------------------------------

    \7\ This adoption includes the citations in the referenced 
section of the Healthcare ETS, which are also included in the docket 
for this ETS.
---------------------------------------------------------------------------

    The Delta variant is transmitted from infectious individuals via 
the same routes as previous variants, but is much more transmissible. 
Specifically, Delta differs from previous dominant variants of SARS-
CoV-2 in terms of the amplification of viral particles expelled from 
infected individuals. Testing of Delta-infected individuals indicates 
that their viral loads are--on average--approximately 1,000x greater 
than those of the SARS-CoV-2 variants from the first COVID-19 wave in 
early 2020. This finding suggests much faster replication of viral 
particles during early infection with the Delta variant, resulting in 
greater infectiousness (contagiousness) when compared to earlier 
versions of SARS-CoV-2 (Li et al., July 12, 2021).
    The transmissibility of viruses is measured in part by the average 
number of subsequently-infected people (or secondary cases) that are 
expected to occur from each existing case (often referred to as 
R0). Several comparisons of the transmissibility of the 
initial SARS-CoV-2 variants to the Delta variant have shown that Delta 
is approximately twice as transmissible (contagious) as previous 
versions of SARS-CoV-2 (CDC, August 26, 2021; Riou and Althaus, January 
30, 2020; Li et al., July 12, 2021; Liu and Rocklov, August, 4, 2021), 
likely the result of higher initial viral loads during the pre-
symptomatic phase (Li et al., July 12, 2021). In addition, as described 
further below, data on Delta shows that both unvaccinated and 
vaccinated individuals are more likely to transmit Delta than previous 
variants (Liu and Rocklov, August, 4, 2021; Eyre et al., September 29, 
2021), making it especially dangerous to those who remain unvaccinated.
c. Health Effects
    COVID-19 infections can lead to death. As reported in the 
Healthcare ETS, by May 24, 2021, there had been 587,432 deaths and 
32,947,548 million infections in the U.S. alone (CDC, May 24, 2021a; 
CDC, May 24, 2021b). At that point in the pandemic, 1.8 out of every 
1,000 people in the U.S. had died from COVID-19 (CDC, May 24, 2021a). 
Since then, reported cases have increased to 44,857,861 and the number 
of deaths has increased to 723,205 (CDC, October 18, 2021- Cumulative 
US Cases; Cumulative US Deaths). By September 2021, an astounding 1 in 
500 Americans had died from COVID-19 (Keating, September 15, 2021). 
Updated mortality data \8\ currently indicate that people of working 
age (18-64 years old) now have a 1 in 202 chance of dying when they 
contract the disease, with the risk much higher (1 in 72) for those 
aged 50-64 (CDC, October 18, 2021--Demographic Trends, Cases by Age 
Group; CDC, October 18, 2021--Demographic Trends, Deaths by Age Group). 
For a more in-depth description of the health effects resulting from 
SARS-CoV-2 infection, see the preamble to the Healthcare ETS (86 FR 
32383-32392), which is hereby included in the record of this ETS.\9\
---------------------------------------------------------------------------

    \8\ Risk of death is based on averages from reported CDC data. 
Risks of hospitalization and death are much higher in unvaccinated 
individuals, as discussed further in Grave Danger, Section III.A.IV. 
Vaccines Effectively Reduce Severe Health Outcomes from and 
Transmission of SARS-CoV-2.
    \9\ This adoption includes the citations in the referenced 
section of the Healthcare ETS, which are also included in the docket 
for this ETS.
---------------------------------------------------------------------------

    Apart from fatal cases, COVID-19 can cause serious illness, 
including long-lasting effects on health. Many patients who become ill 
with COVID-19 require hospitalization. Indeed, updated CDC 
hospitalization and mortality data indicate that working age Americans 
(18-64 years old) now have a 1 in 14 chance of hospitalization when 
infected with COVID-19 (CDC, October 18, 2021--Demographic Trends, 
Cases by Age; Total Hospitalizations, by Age). Those who are 
hospitalized frequently need supplemental oxygen and treatment for the 
disease's most common complications, which include pneumonia, 
respiratory failure, acute respiratory distress syndrome (ARDS), acute 
kidney injury, sepsis, myocardial injury, arrhythmias, and blood clots. 
One study, which included 35,502 inpatients nationwide, determined that 
the median length of hospital stay was 6 days, unless the cases 
required ICU treatment. For those cases, ICU stays were on median 5 
days in addition to the time spent hospitalized outside of the ICU 
(Rosenthal et al., December 10, 2020). Another study that assessed 
hospital length of stay for COVID-19 patients in England estimated that 
a non-ICU hospital stay averaged between 8 and 9 days, but those 
estimates ranged from approximately 12 to 18 days when patients were 
admitted to the ICU (Vekaria et al., July 22, 2021). Moreover, given 
that SARS-CoV-2 is still a novel virus, the severity of long-term 
health effects--such as ``post-COVID conditions''--are not yet fully 
understood.
    Many members of the workforce are at increased risk of death and 
severe disease from COVID-19 because of their age or pre-existing 
health conditions. The comorbidities that further exacerbate COVID-19 
infections are common among adults of working age in the U.S. For 
instance, 46.1% of individuals with cancer are in the 20-64 year old 
age range (NCI, April 29, 2015), and over 40% of working age adults are 
obese (Hales et al., February 2020). Disease severity is also likely 
exacerbated by long-standing healthcare inequities experienced by 
members of many racial and economic demographics (CDC, April 19, 2021).
    Recent data suggests that Delta variant infections may result in 
even more severe illness and a higher frequency of death than previous 
COVID-19 variants due to Delta's increased transmissibility, virulence, 
and immune escape (Fisman and Tuite, July 12, 2021). Symptomatic Delta 
variant infections do occur in fully vaccinated people (Mlcochova et 
al., June 22, 2021; Musser et al., July 22, 2021); however, as reported 
by the CDC (CDC, August 26, 2021), the vast majority of the continuing 
instances of severe and fatal COVID-19 infections are occurring in 
unvaccinated persons (discussed further in Grave Danger, Section 
III.A.IV. Vaccines Effectively Reduce Severe Outcomes from and 
Transmission of SARS-CoV-2). An assessment of Delta-related hospital 
admissions in Scotland found that hospitalizations were approximately 
doubled in patients with the Delta variant when compared to the Alpha 
variant (Sheikh et al., June 4, 2021). A similar study conducted using 
a retrospective cohort in Ontario, Canada compared the virulence of 
novel SARS-CoV-2 variants and found that the incidences of 
hospitalization, ICU admission, and death were more pronounced with the 
Delta variant than any other SARS-CoV-2 variant (Fisman and Tuite, July 
12, 2021). A large national cohort study that included all Alpha and 
Delta SARS-CoV-2 patients in England between March 29 and May 23, 2021 
found a ``higher hospital admission or emergency care attendance risk 
for patients with COVID-19 infected with the Delta variant compared 
with the Alpha variant,'' suggesting that Delta outbreaks--especially 
amongst unvaccinated populations--may lead to more severe health 
consequences and an equivalent or greater burden on healthcare services 
than the Alpha variant (Twohig et al., August 27, 2021). However, one 
more recent study examining data from several U.S. states demonstrated 
a significant increase in hospitalization from the pre-Delta to the 
Delta period, which may be related to increased transmissibility of 
Delta rather than


more severe health outcomes (Taylor et al., October 22, 2021).
III. Impact on the Workplace
    SARS-CoV-2 is readily transmissible in workplaces because they are 
areas where multiple people come into contact with one another, often 
for extended periods of time. When employees report to their workplace, 
they may regularly come into contact with co-workers, the public, 
delivery people, patients, and any other people who enter the 
workplace. Workplace factors that exacerbate the risk of transmission 
of SARS-CoV-2 include working in indoor settings, working in poorly-
ventilated areas, and spending hours in close proximity with others. 
Full-time employees typically spend 8 hours or more at work each shift, 
more time than they spend anywhere else but where they live. Employees 
work in proximity to others in workplaces that were not originally 
designed to keep people six feet away from other people and that may 
make it difficult for employees to perform work tasks while maintaining 
a six-foot distance from others. Even in the cases where workers can do 
most of their work from, for example, a private office within a 
workplace, they share common areas like hallways, restrooms, lunch 
rooms and meeting rooms. Furthermore, many work areas are poorly 
ventilated (Allen and Ibrahim, May 25, 2021; Lewis, March 30, 2021). An 
additional factor that exacerbates the risk of transmission of SARS-
CoV-2 is interacting with or caring for people with suspected or 
confirmed COVID-19; this was a primary driver of OSHA's determination 
of grave danger for healthcare workers in the Healthcare ETS (see 86 FR 
32381-32383). In recent weeks, the majority of states in the U.S. have 
experienced what CDC defines as ``high or substantial community 
transmission,'' indicating that there is a clear risk of the virus 
being introduced into and circulating in workplaces (CDC, October 18, 
2021--Community Transmission Rates).
    Although COVID-19 is not exclusively an occupational disease, it is 
evident from research accrued since the beginning of the pandemic that 
SARS-CoV-2 transmission can and does occur in workplaces, affecting 
employees and their lives, health, and livelihoods. This continues to 
be true for the Delta variant, with its increased transmissibility and 
potentially more severe health effects. This section describes some of 
the clusters, outbreaks, and other occurrences of workplace COVID-19 
cases that government agencies, researchers, and journalists have 
described, and the widespread effects of SARS-CoV-2 in industry sectors 
across the national economy. While the focus is on more recent data 
reflecting the impact of the Delta variant, evidence of workplace 
transmission that occurred prior to the emergence of the Delta variant 
is also presented.
    The workplace-based clusters described below provide evidence that 
workplaces in a wide range of industries have been affected by COVID-
19, that many employees face exposure to infected people in their 
workspaces, and that SARS-CoV-2 transmission is occurring in the 
workplace, including during the recent period where the Delta variant 
has predominated. Although the presence of a cluster on its own does 
not necessarily establish that the cluster is work-related (i.e., a 
result of transmission at the worksite), many state investigation 
reports and published studies provide evidence that transmission is 
work related by documenting that infections at a workplace occurred 
within 14-days (the incubation period for the virus) of each other and 
ruling out the possibility that transmission occurred outside the 
workplace. In addition, the information below demonstrates that 
exposures to SARS-CoV-2 happen regularly in a wide variety of different 
types of workplaces.
    The basis for OSHA's grave danger finding is that employees can be 
exposed to the virus in almost any work setting; that exposure to SARS-
CoV-2 can lead to infection (CDC, September 21, 2021); and that 
infection in turn can cause death or serious impairment of health, 
especially in those who are unvaccinated (see Section III.A.IV. 
Vaccines Effectively Reduce Severe Health Outcomes from and 
Transmission of SARS-CoV-2). The information described in this section 
supports OSHA's finding that employees who work in spaces shared by 
others are at risk of exposure to SARS-CoV-2. The degree of risk from 
droplet-based transmission may vary based on the duration of close 
proximity to a person infected with SARS-CoV-2, including the Delta 
variant, but the simple and brief act of sneezing, coughing, talking, 
or even breathing can significantly increase the risk of transmission 
if controls are not in place. SARS-CoV-2, including the Delta variant, 
might also be spread through airborne particles under certain 
conditions, particularly in enclosed settings with inadequate 
ventilation, which are common characteristics of some workplaces.
    The peer-reviewed scientific journal articles, government reports, 
and news articles described below establish the widespread prevalence 
of COVID-19 among employees, beginning with a description of the recent 
impact from the Delta variant. OSHA's findings are based primarily on 
the evidence from peer-reviewed scientific journal articles and 
government reports. However, peer review for scientific journal 
articles and the assembly of information for government reports and 
other official sources of information take time, and therefore those 
sources do not always reflect the most up-to-date information (Chan et 
al., December 14, 2010). In addition, while state and local health 
departments can report workplace outbreaks to CDC, the agency does not 
provide summary statistics by workplace so that those outbreaks can be 
tracked on a national level. In the context of the COVID-19 pandemic, 
given the recent impacts due to the Delta variant and the emergence of 
new information on a daily basis, it is critical for OSHA to rely on 
the most up-to-date information available. Therefore, OSHA has 
occasionally supplemented peer-reviewed data and government reports 
with additional information on occupational outbreaks contained in 
other sources of media (e.g., newspapers, digital media, and 
information submitted to or obtained by private organizations).\10\ The 
reported information from other sources can provide further evidence of 
the impact of an emerging and changing disease, especially for 
industries that are not well represented in the peer-reviewed 
scientific literature. Together, these sources of information represent 
the best available evidence of the impact on employees of the pandemic 
thus far.
---------------------------------------------------------------------------

    \10\ OSHA did not make findings based solely on non-peer-
reviewed sources such as news articles, but the agency found that 
those sources can sometimes provide useful information when 
considered with more robust sources.
---------------------------------------------------------------------------

    The information described herein illustrates a significant number 
of infections among employees in a variety of industries, with 
virtually every state continuing to experience what CDC defines as high 
or substantial community transmission related to the recent surge of 
the Delta variant. The industries and types of workplaces described are 
not the only ones in which a grave danger exists. The science of 
transmission does not vary by industry or by type of workplace. OSHA 
therefore expects transmission to occur in diverse workplaces all 
across the country (see Dry Color Mfrs. Ass'n, Inc. v. Dep't of Labor, 
486 F.2d 98, 102 n.3 (3d Cir. 1973) (holding that when OSHA determines 
a substance poses a grave


danger to workers, OSHA can assume an exposure to a grave danger exists 
wherever that substance is present in a workplace)). In addition, the 
severity of COVID-19 does not depend on where an employee is infected; 
an employee exposed to SARS-CoV-2 might die whether exposed while 
working at a meat packing facility, a retail establishment, or an 
office (see Grave Danger, Section III.A.V.b. Employees Who Work 
Exclusively Outside, below, for a discussion of the risk of exposure in 
outdoor workplaces).
a. General Impact on Workers
    Data on SARS-CoV-2 infections, illnesses, and deaths among 
employees in general industry, agriculture, construction, and maritime 
support OSHA's finding that COVID-19 poses a grave danger to employees 
in these sectors across the U.S. economy. This section summarizes 
studies and reports of COVID-19 illness and fatalities in a wide range 
of workplaces across those industry sectors. Not all workplace settings 
are discussed; nor is the data available to do so. However, the 
characteristics of the various affected workplaces--such as indoor work 
settings; contact with coworkers, clients, or members of the public; 
and sharing space with others for prolonged periods of time--indicate 
that exposures to SARS-CoV-2 are occurring in a wide variety of work 
settings across all industries. Therefore, most employees who work in 
the presence of other people (e.g., co-workers, customers, visitors) 
need to be protected.
    While there is no comprehensive source of nationwide workplace 
infection data, reports from states and communities on outbreaks 
related to workplaces provide key, up-to-date data that illustrate the 
likelihood of employee exposure to SARS-CoV-2 at workplaces throughout 
the U.S. OSHA identified a number of recent reports from various 
regions of the country that together demonstrate the impact that SARS-
CoV-2 can have on a variety of workplaces, including in service 
industries (e.g., restaurants, grocery and other retail stores, fitness 
centers, hospitality, casinos, salons), corrections, warehousing, 
childcare, schools, offices, homeless shelters, transportation, mail/
shipping/delivery services, cleaning services, emergency services/
response, waste management, construction, agriculture, food packaging/
processing, and healthcare. Deaths are reported in many studies 
performed prior to the emergence of the Delta variant but, because the 
Delta outbreak is so recent and deaths can occur weeks after infection, 
the number of deaths from recent infections might be underestimated. 
Some of the reports include cumulative data representing various phases 
of the pandemic, beginning prior to the availability of vaccines and 
continuing through the recent surge of the Delta variant. In addition, 
some studies report investigations of recent outbreaks, which provide 
insight on the impact of the Delta variant as well as impacts 
associated with the current vaccination status of workers.
    The Washington State Department of Health (WSDH) reports outbreaks 
occurring in non-healthcare workplaces (WSDH, September 8, 2021). In 
non-healthcare workplaces, outbreaks are defined as two or more 
laboratory confirmed cases of COVID-19, with at least two cases 
reporting symptom onset within 14 days of each other, and plausible 
epidemiological evidence of transmission in a shared location other 
than a household. As of September 4, 2021, WSDH reported 5,247 
outbreaks in approximately 40 different types of non-healthcare work 
settings. During the week of August 29 through September 4, 2021, WSDH 
identified 137 separate workplace outbreaks. The types of non-medical 
workplace settings that represented more than 5% of the total outbreaks 
during that week included food service/restaurants, childcare, schools, 
retail, grocery, and shelter/homeless services. Other types of non-
healthcare settings where outbreaks occurred recently included non-food 
and food manufacturing, construction, professional services/office 
based, agriculture/produce packing, transportation/shipping delivery, 
government agencies/facilities, leisure hospitality/recreation, 
corrections, utilities, warehousing, facility/domestic cleaning 
services, youth sports/activities, camps, and public safety. Over the 
course of the pandemic, outbreaks have also been observed at bars/
nightclubs, hotels, and fishing/commercial seafood vessels.
    The Oregon Health Authority (OHA) publishes a weekly report 
detailing outbreaks directly related to work settings. OHA 
epidemiologists consider cases to be part of a workplace outbreak when 
clusters form with respect to space and time, within a plausible 
incubation period for the virus, and their investigation does not 
uncover an alternative source for the outbreak. For privacy reasons, 
OHA only reports outbreaks with 5 or more cases in workplaces with 30 
or more people. OHA reported a total of 26,013 cases and 135 deaths 
related to workplace outbreaks as of September 1, 2021. As of September 
1, 2021, OHA was investigating more than 124 active workplace outbreaks 
(OHA, September 1, 2021). Those outbreaks occurred in a wide variety of 
industries including correctional facilities, emergency services, waste 
management, schools and child care, retail and grocery stores, 
restaurants, warehousing, agriculture, food processing/packaging, 
construction, healthcare, mail and delivery services, office locations, 
utilities, transportation, and others.
    Tennessee Department of Health was investigating 557 active COVID-
19 clusters as of September 8, 2021 (TDH, September 8, 2021). Clusters 
are defined as two or more laboratory confirmed COVID-19 cases linked 
to the same location or event that is not a household exposure. The 
clusters occurred in 13 types of settings, 10 of which were workplace 
settings. Outbreaks at workplaces represented more than half of the 
total active outbreaks in the state at that time. Settings comprising 
more than 5% of total clusters included assisted care living 
facilities, nursing homes, and correctional facilities. Other types of 
workplaces where outbreaks occurred included bars, construction, farms, 
homeless shelters, and industrial settings.
    The North Carolina Department of Health and Human Services reports 
cumulative numbers of clusters, cases, and deaths for workers in 
poultry processing facilities (beginning in April of 2020) and other 
types of workplaces (beginning in May of 2020) (NCDHHS, August 30, 
2021). Clusters are defined as a minimum of 5 cases with illness onset 
or initial positive results within a 14-day period and plausible 
epidemiological linkage between the cases. Plausible epidemiological 
linkage means that multiple cases were in the same general setting 
during the same time period (e.g., same shift, same physical area) and 
that a more likely source of exposure is not identified (e.g., 
household contact or close contact to a confirmed case in another 
setting). During that time period of April/May 2020 through August 30, 
2021, workplaces \11\ were associated with nearly 80% of the 1,969 
clusters and 27,097 cases observed and nearly 40% of the 167 deaths 
related to the clusters. Cumulative numbers of cluster-associated 
deaths were highest in meat and poultry processing (25 of 5,351 cases), 
followed by healthcare (10 of 1,036 cases), government services and 
manufacturing (5 of 1,048 cases and 5 of


1,856 cases, respectively), and restaurants and childcare (3 of 421 
cases and 3 of 1,943 cases, respectively). Recently, in July of 2021, 
the number of cases associated with workplace clusters began increasing 
in several different types of work settings, including meat processing, 
manufacturing, retail, restaurants, childcare, schools, and higher 
education.
---------------------------------------------------------------------------

    \11\ NCDHHS identifies a ``workplace'' category in their report 
(e.g., agriculture, construction), but OSHA includes other settings 
where employees would be present (e.g., retail, restaurants, 
childcare, healthcare).
---------------------------------------------------------------------------

    Colorado Department of Public Health & Environment/Colorado State 
Emergency Operations Center (CDPHE/CSEOC, September 8, 2021) reported 
5,584 resolved workplace-related outbreaks involving 40,156 employee 
cases and 79 employee deaths since May of 2020. The agency's current 
investigations, as of September 8, 2021 included 291 active outbreaks 
(not defined), with 2,865 staff cases (assumed to be cases in 
employees). The majority of active outbreaks were reported in 
childcare, schools, healthcare, and corrections. Active outbreaks were 
also reported in construction, retail, homeless shelters, casinos, 
restaurants, hotels, offices, law enforcement, manufacturing, delivery 
services, and warehouses. Other types of work settings that were 
affected in resolved outbreaks included warehouses, bars, government 
locations, waste management, utilities, salons, emergency services, 
meat processing/packaging, and postal services. From June 21, 2021 (the 
date the healthcare ETS was published) through September 8, 2021, 1,469 
staff cases associated with outbreaks were reported, for an average of 
approximately 19 cases per day.
    Similar reporting is available from Louisiana's Department of 
Health (LDH, August 24, 2021), with 1,347 outbreaks and 9,130 cases 
reported as of August 24, 2021. LDH defines an outbreak as 2 or more 
cases among unrelated individuals who visited a site within a 14-day 
period. More than three quarters of outbreaks through that date were 
associated with workplaces. Workplace settings in Louisiana that 
experienced more than 5% of outbreaks included day care facilities, 
bars, restaurants, retail settings, industrial settings, and office 
spaces. Other types of workplace settings or industries where outbreaks 
occurred included casinos, gyms/fitness centers, banks, automotive 
services, construction, and ships/boats.
    In addition to the state data above, some published studies and 
government reports provide information on recent workplaces outbreaks. 
For example, 47 people, including 3 of 11 staff members, 23 gymnasts, 
and 21 household contacts, contracted COVID-19 from an outbreak linked 
to an Oklahoma gymnastics facility during April 15 through May 3, 2021 
(Dougherty et al., July 16, 2021). All 21 of the virus samples 
sequenced were determined to be the Delta variant. The majority of the 
infected individuals (85%) were unvaccinated. Infections were reported 
in 16 adults aged 20 years or older; two adults were hospitalized and 
one required intensive care.
    The state of Hawaii defines clusters as three or more confirmed or 
probable cases linked to a site or event within 14 days, with no 
outside exposure of cases to each other (Hawaii State, August 19, 
2021). The state reported a COVID-19 cluster in July associated with a 
concert at a bar that affected 16 people, including employees, band 
members, and concert attendees; infections also spread to 7 household 
members. Band members had performed while sick. Four of the initial 16 
people and none of the household members who tested positive for COVID-
19 were fully vaccinated. The concert cluster was linked to clusters at 
another workplace and another concert. The report lists additional 
clusters investigated in the two weeks prior to the report; those 
clusters were observed in workplace locations such as correctional 
facilities, bars and nightclubs, restaurants, construction/industrial 
sites, travel/lodging/tourism, schools, food suppliers, and gyms.
    Additional evidence that employees are at risk of exposure to SARS-
CoV-2 in the workplace is available from published, peer-reviewed 
studies that were conducted before the Delta variant emerged. Those 
studies demonstrate that employees have been at risk of infection, 
illness, and death throughout the COVID-19 pandemic. Because the Delta 
variant is more transmissible and likely causes more severe disease 
than previous variants, there is even greater potential for 
unvaccinated employees to become seriously ill or die as a result of 
exposure to the Delta variant.
    Contreras et al. (July, 2021) examined workplace outbreaks 
(excluding healthcare settings, homelessness services, and emergency 
medical services) in Los Angeles county from March 19 through September 
30, 2020. Workplace outbreaks were defined as 5 or more suspected or 
laboratory confirmed COVID-19 cases (prior to May 29) or 3 or more 
laboratory confirmed cases (after May 29) occurring within 14 days. 
Nearly 60% of the 698 identified outbreaks occurred in three sectors--
manufacturing (184, 26.4%), retail trade (137, 19.6%), and 
transportation and warehousing (73, 10.5%). Also notable were the 71 
outbreaks in the accommodation and food services industry, which 
represented 10.2% of the outbreaks. The study authors concluded that 
outbreaks were larger and lasted longer at facilities with more onsite 
staff.
    Outbreaks in Wisconsin from March 4 through November 16, 2020 were 
also examined (Pray et al., January 29, 2021). Non-household outbreaks 
were defined as two or more confirmed COVID-19 cases that occurred 
within 14 days in persons who attended the same facility or event and 
did not share a household. During the period from March 4 through 
November 16, 2020, the largest percentages of cases were associated 
with outbreaks in long-term care facilities (26.8% of cases), 
correctional facilities (14.9% of cases), and colleges or universities 
(15% of cases). Also notable were the substantial number of cases 
associated with outbreaks in food production or manufacturing 
facilities (including meat processing and warehousing; 14.5% of cases) 
and schools and childcare facilities (10.6% of cases).
    Bui et al. (August 17, 2020) analyzed data from the Utah Department 
of Health's COVID-19 case surveillance system, which included data on 
workplace outbreaks. Outbreaks were defined as two or more laboratory 
confirmed cases occurring within a 14 day period among coworkers in a 
common workplace (e.g., same facility). During the time period between 
March 6 and June 5, 2020, 277 COVID-19 outbreaks were reported, of 
which 210 (76%) occurred in workplaces. The 210 workplace outbreaks 
occurred in 15 of 20 industry sectors, and the industry sectors of 
manufacturing (43 outbreaks, 20%), construction (32 outbreaks, 15%), 
and wholesale trade (29 outbreaks, 14%) together represented nearly 
half of workplace outbreaks. Other sectors that represented more than 
10% of total outbreaks were retail trade (28 outbreaks, 13%) and 
accommodation and food services (25 outbreaks, 12%). Incidence rates of 
COVID-19 over the period of March 6 through June 5, 2020 were 339/
100,000 workers in manufacturing, 122/100,000 workers in construction, 
377/100,000 workers in wholesale trade, 68/100,000 workers for retail 
trade, and 78/100,000 workers for accommodation and food services. For 
COVID-19 cases associated with workplace outbreaks in which 
hospitalization and severity status were known (1,382 and 1,155, 
respectively), the number in all sectors who were admitted to the 
hospital was 85 (6%) and the number with severe outcomes (intensive 
care unit admission, mechanical ventilation, or death) was 40 (3%).


    The impact of SARS-CoV-2 exposures on employee infection, illness, 
and death has also been demonstrated in studies focusing on specific 
types of industries, such as those where employees have frequent 
contact with each other and the public (e.g., grocery stores, bars, 
fitness facilities, schools, and law enforcement/corrections). For 
example, a study by Lan et al. (September 26, 2020) demonstrates the 
risk of infection in service industries. The cross-sectional study 
examined the risks of SARS-CoV-2 exposure and infection for employees 
in a Boston, Massachusetts-area retail grocery store market. The study 
tested 104 grocery store employees, of whom 20% (21 employees) were 
positive for COVID-19; 76% of confirmed cases did not have symptoms. 
After adjusting for gender, smoking, age, and the prevalence of COVID-
19 in the employees' residential communities, employees who had direct 
customer exposure (e.g., cashiers, sales associates, cart attendants) 
were 5.1 times more likely to have a positive test for COVID-19 than 
employees without direct face-to-face customer exposure (e.g., 
stockers, backroom, receiving and maintenance). The infection rate of 
20% among all employees was significantly higher than the rate in the 
surrounding community.
    In February of 2021, an event at an Illinois bar that accommodates 
approximately 100 people resulted in a COVID-19 outbreak that affected 
46 people, including 3 (10%) staff members, 26 (90%) patrons, and 17 
secondary cases (Sami et al., April 9, 2021). People at the event 
included an asymptomatic person diagnosed with COVID-19 on the previous 
day and 4 symptomatic people who were later diagnosed with COVID-19. 
The outbreak resulted in a school closure and the hospitalization of a 
resident at a long-term care facility.
    In Minnesota, 47 COVID-19 outbreaks were detected at fitness 
facilities from August through November of 2020 (Suhs et al., July 23, 
2021). One outbreak at a fitness facility during October through 
November of 2020 resulted in 23 COVID-19 cases including 5 (22%) 
employees and 18 (78%) members. A genetic analysis of specimens from 3 
employees and 10 members identified 2 distinct genetic subclusters, 
indicating two distinct chains of transmission among members and 
employees.
    School-related outbreaks were examined from December 1, 2020 
through January 22, 2021 in eight public elementary schools of a 
Georgia school district (Gold et al., February 26, 2021). A COVID-19 
case was determined to be school-related if (1) symptom onset or a 
positive test was consistent with the incubation period of the virus 
following contact with an index case or a school-associated case, (2) 
close contact occurred with the index case or school-associated case 
while that person was infected, and (3) no known contact occurred with 
an infected community or household contact in the two weeks prior to a 
positive test for COVID-19. The investigators identified nine clusters 
of three or more epidemiologically linked COVID-19 cases that involved 
13 educators and 32 students in six of the eight elementary schools. 
Approximately half of the school-associated cases involved two clusters 
that began with probable transmission between educators, followed by 
educator to student transmission. Eighteen of 69 household members 
tested received positive results.
    A number of studies demonstrate the impact of COVID-19 in law 
enforcement and related fields such as corrections. For example, a 
study examining COVID-19 antibodies in employees from public service 
agencies in the New York City area from May through July of 2020, found 
that 22.5% of participants had COVID-19 antibodies (Sami et al., March, 
2021). The percentage of correctional officers found to have COVID-19 
antibodies (39.2%) was the highest observed among all the occupations. 
The percentages of police dispatchers, traffic officers, security 
guards, and dispatchers found to have COVID-19 antibodies (29.8 to 
37.3%) were among the highest levels observed in all the occupations. 
The study authors noted that those jobs involve frequent or close 
contact with the public or are done in places where employees work in 
close proximity to their coworkers.
    Wallace et al. (May 15, 2020) evaluated data on COVID-19 cases and 
deaths among correctional facility employees and inmates from January 
21 to April 21, 2020. Data were reported to CDC by 37 (69%) of 54 state 
and territorial health department jurisdictions. Of these 37 
jurisdictions, 32 (86%) reported at least one COVID-19 case from a 
correctional facility. Of the 420 facilities with a case, 221 (53%) 
reported cases only among staff members. In total, 4,893 COVID-19 cases 
among incarcerated or detained persons and 2,778 cases among staff 
members were reported (total tested not provided). Among staff member 
cases, 79 hospitalizations (3%) and 15 deaths (1%) were reported. The 
study authors noted that ``correctional and detention facilities face 
challenges in controlling the spread of infectious diseases because of 
crowded, shared environments and potential introductions by staff 
members and new intakes.''
    Ward et al. (June 2021) analyzed COVID-19 prevalence among 
prisoners and staff in 45 states from March 31, 2020 through November 
4, 2020. During that time period, COVID-19 cases in staff were 3 to 5 
times higher compared to the U.S. population. Average daily increases 
in cases were 42 per 100,000 prison employees, 61 per 100,000 
prisoners, and 13 per 100,000 U.S. residents. On November 4, 2020, 
COVID-19 prevalence for prison staff was 9,316 cases per 100,000 
employees, which was 3.2 times greater than prevalence in the U.S. 
population (2,900 cases per 100,000).
    Kirbiyik et al. (November 6, 2020) analyzed movement through a 
network-informed approach to identify likely high points of 
transmission within the Cook County Jail in Chicago, IL. At that 
facility, over 900 COVID-19 cases were reported across 10 housing 
divisions in 13 buildings from March 1-April 30, 2020. Staff members 
were required to report symptoms of COVID-19 (probable cases) or 
receipt of a positive test result (confirmed cases). A total of 2,041 
staff members (77% of staff) were included in the network analysis 
because information was available about their shift and division 
assignments, and 198 (9.7%) of those staff members had COVID-19 during 
the two-month study period. Connections between staff members who had 
COVID-19 were higher than expected, suggesting likely transmission 
among staff members. Fewer connections than expected were observed 
among detained persons with SARS-CoV-2 infections, suggesting the 
effectiveness of medical isolation at reducing transmission.
    The Officer Down Memorial Page, which tracks police officer 
fatalities determined to be occupationally related, reported that the 
majority of officer deaths for 2021 (157 of 269) were related to COVID-
19 (ODMP, September 14, 2021). For the 269 officers who died, causes of 
death were not reported for each month, but the highest numbers of 
monthly deaths, 52 in January and 65 in August (compared to 16 to 34 
deaths on other reported months), were consistent with the winter surge 
of COVID-19 and, more recently, the surge caused by the Delta variant.
    The risk of COVID-19 has also been examined in industries where 
employees have little contact with the public, such as construction, 
and food processing, and where most exposure to


SARS-CoV-2 likely comes from other workers. Pasco et al. (October 29, 
2020) examined the association between construction work during the 
COVID-19 pandemic and community transmission and construction worker 
hospitalization rates in Austin, Texas from March 13 to August 20, 
2020. A ``Stay Home-Work Safe'' order enacted on March 24, 2020, 
limited construction to only critical infrastructure and excluded 
commercial and residential work. One week later, the Texas governor 
lifted the restriction for essential workers and allowed all types of 
construction work to resume, while keeping the order in place for other 
workers. The authors found that resuming construction during the 
shelter-in-place order led to an increase in community transmission, an 
increase in hospitalizations among community members, and an increase 
in hospitalizations of construction workers. By mid-July, Austin Public 
Health identified at least 42 clusters (not defined) of COVID-19 cases 
in the construction industry; 515 individuals were hospitalized for 
COVID-19 illnesses acquired as part of these clusters, and 77 of those 
reported working in construction. The study found that construction 
workers had a nearly 5-fold increased risk of hospitalization in 
central Texas compared with workers in other occupations. The authors' 
model predicted that allowing unrestricted construction work would be 
associated with an increase in COVID-19 hospitalization rates from 0.38 
per 1,000 residents to 1.5 per 1,000 residents overall, and from 0.22 
per 1,000 construction workers to 9.3 per 1,000 construction workers 
for the construction industry specifically. The authors concluded that 
stringent workplace safety measures could significantly mitigate risks 
related to COVID-19 in the industry.
    The meat packing and processing industries and related agricultural 
and food processing sectors have also been impacted by COVID-19. 
Waltenburg et al. (January, 2021) reported COVID-19 cases in employees 
from meat and poultry processing facilities in 31 states from March 1 
through May 31, 2020. As reported in Table 2 of that report, 28,364 
employees in those facilities were confirmed to have COVID-19 by 
laboratory testing and 132 died. Among the 20 states that reported 
total numbers of employees, 11.4% of the workers were diagnosed with 
COVID-19 (with a range of 3.1 to 27.7% of workers in individual 
states). For states that reported at least one COVID-19-related death, 
the percentages of employees who died in each state ranged from 0.1 to 
2.4% of those with COVID-19. The authors found a high burden of disease 
in persons employed at these facilities who were racial or ethnic 
minorities. Higher incidence in these populations might be due to the 
likelihood of these employees working in areas in the plant where 
transmission risk is higher. Steinberg et al. (August 7, 2020) reported 
that attack rates (i.e., the number of individuals who are infected in 
comparison to the total number at risk) among production employees in 
the Cut (30.2%), Conversion (30.1%), and Harvest (29.4%) departments of 
a meat processing plant (where spacing between employees is less than 6 
feet) were double that of salaried employees (14.8%) whose workstations 
had been modified to increase physical distancing from others.
    Waltenburg et al. (January, 2021) also evaluated COVID-19 incidence 
in food manufacturing and agricultural settings (e.g., manufacturing or 
farming involving fruits, vegetables, dairy, baked goods, eggs, 
prepared foods), as reported in 30 states from March through May 2020. 
In food manufacturing and farming of fruits, vegetables, dairy, and 
other items, 742 workplaces were affected, including 8,978 infections 
and 55 fatalities. For states that reported total numbers of employees, 
the proportion of employees who developed COVID-19 in each state ranged 
from 2.0 to 43.5%. For states that reported at least one death, the 
percentages of deaths among cases ranged from 0.1 to 3.8%.
    Porter et al. (April 30, 2021) reported that 13 COVID-19 outbreaks 
occurred at Alaska seafood processing facilities and vessels (both of 
which were described as high density workplaces) during the Summer and 
early Fall of 2020. The 13 outbreaks involved 539 COVID-19 cases, with 
2-168 cases per outbreak. Attack rates in facilities and offshore 
vessels ranged from less than 5% to 75%. Outbreaks were also reported 
in entry quarantine groups. Because of these outbreaks, it was 
determined that vaccination of these essential workers is important and 
requirements for COVID-19 prevention were updated to include smaller 
quarantine groups, serial testing, and testing before transfers from 
one facility or vessel to another.
    Finally, two published studies analyzed death records to determine 
how mortality rates among individuals in various types of workplaces 
had changed during the pandemic. Chen et al. (June 4, 2021) analyzed 
records of deaths occurring on or after January 1, 2016 in California 
and found that mortality rates in working aged adults (18-65 years) 
increased 22% during the COVID-19 pandemic period of March through 
November 2020 compared to pre-pandemic periods. Relative to pre-
pandemic periods, the groups of employees experiencing the highest, 
statistically significant increases in relative excess mortality were 
those in food/agriculture (39% increase), transportation/logistics (31% 
increase), facilities (23% increase), and manufacturing (24% increase). 
Other groups that also experienced excess, statistically significant 
mortality compared to pre-pandemic periods were health or emergency 
workers (17% increase), retail workers (21% increase), and government 
and community workers (17% increase). The study authors concluded that 
certain occupational sectors were impacted disproportionally by 
mortality during the pandemic and that essential work conducted in-
person is a likely avenue of infection transmission.
    Hawkins et al. (January 10, 2021) examined death certificates of 
individuals who died in Massachusetts between March 1 and July 31, 
2020. An age-adjusted mortality rate of 16.4 per 100,000 employees was 
determined from 555 death certificates that had useable occupation 
information. Employees in 11 occupational groups had particularly high 
mortality rates: healthcare support; transportation and material 
moving; food preparation and serving; building and grounds cleaning and 
maintenance; production, construction and extraction; installation/
maintenance/repair; protective services; personal care services; arts/
design/entertainment; sports/media; and community and social services. 
The study authors noted that occupational groups expected to have 
frequent contact with sick people, close contact with the public, and 
jobs that are not practical to do from home had particularly elevated 
mortality rates.
b. Healthcare Workers
    As explained in the Healthcare ETS, COVID-19 presents a grave 
danger to workers in all U.S. healthcare settings where people with 
COVID-19 are reasonably expected to be present (86 FR 32381). 
Healthcare settings covered by the Healthcare ETS primarily include 
settings where people with suspected or confirmed COVID-19 are treated, 
exacerbating the risk present in most workplaces. To control the higher 
level of risk in those settings, OSHA determined that a suite of 
workplace controls was necessary to protect all employees, whether they 
are vaccinated or unvaccinated. As explained further


below, OSHA now finds that unvaccinated healthcare workers in 
healthcare settings not covered by the Healthcare ETS are also at grave 
danger from exposure to SARS-CoV-2, just like unvaccinated workers in 
other industries. Data continue to be collected and reported for 
healthcare workers, and a small number of peer-reviewed studies 
demonstrate the potential impact of the Delta variant on healthcare 
workers.
    CDC continues to provide updates for COVID-19 cases and deaths 
among healthcare personnel. However, information on healthcare 
personnel status continues to be reported for only a fraction (18.91%) 
of total reported cases, and death status was reported for only 82.16% 
of healthcare personnel cases as of October 18, 2021 (CDC, October 18, 
2021--Healthcare Personnel). Given incomplete reporting, the data from 
this source represent only a fraction of actual healthcare cases and 
deaths. Nevertheless, CDC reported 666,707 healthcare personnel cases 
among the 6,754,306 reported cases that included information on 
healthcare personnel status (9.9%) and 2,229 fatalities among the 
547,769 cases that included death status (0.4%) for healthcare 
employees as of October 18, 2021. This is a 26% increase in the number 
of cases and a 27% increase in the number of deaths since the May 24, 
2021 data reported in the ETS (CDC, October 18, 2021--Healthcare 
Personnel). The Delta variant is likely responsible for the majority of 
those deaths. No healthcare worker deaths were reported by CDC during 
the weeks of May 30 through June 13, 2021; however, as the Delta 
variant's prevalence rose after June 20, healthcare worker deaths began 
increasing; they peaked during the period of August 15 through 
September 12, 2021, when 34 to 36 healthcare worker deaths were 
reported per week (CDC October 18, 2021--Healthcare Personnel, Deaths 
by Week). Independent reporting by Kaiser Health News and The Guardian 
reported more than 3,600 fatalities in health care workers as of April 
2021 (Spencer and Jewett, April 8, 2021). That number is expected to be 
higher at this time since the earlier figure did not include the most 
recent 5 months of the pandemic, which includes the period of Delta 
variant predominance.
    Published studies also demonstrate that healthcare workers, 
especially those who are unvaccinated, remain at risk of being infected 
with SARS-CoV-2 (see Section III.A.IV. Vaccines Effectively Reduce 
Severe Health Outcomes from and Transmission of SARS-CoV-2). Routine 
testing of health care personnel, first responders, and other frontline 
workers in eight U.S. locations in six states from December 14, 2020 
through August 14, 2021 revealed 194 infections in 4,136 unvaccinated 
participants (89.7% symptomatic) and 34 infections in 2,976 fully 
vaccinated participants (80.6% symptomatic) (Fowlkes et al., August 27, 
2021). During time periods when the Delta variant represented more than 
50% of viruses sequenced, 19 infections were detected in 488 
unvaccinated participants (94.7% symptomatic) and 24 infections were 
detected in 2,352 vaccinated participants (75% symptomatic).
    Monthly COVID-19 cases in healthcare workers were reported during 
the period from March 1 to July 31, 2021 at the University of 
California San Diego (UCSD) health system, which is a healthcare 
provider that includes primary care services such as family medicine 
and pediatrics (Keehner et al., September 1, 2021; UCSD, 2021). During 
that time period, a total of 227 health care workers tested positive 
for COVID-19. One hundred and nine of 130 fully vaccinated workers who 
tested positive (83.8%) were symptomatic and 80 of 90 unvaccinated 
workers (88.9%) were symptomatic; one unvaccinated person was 
hospitalized for COVID-19 symptoms. By July of 2021, after the end of 
California's mask mandate on June 15 and after the Delta variant became 
dominant, the number of cases detected dramatically increased; the 
Delta variant accounted for more than 95% of SARS-CoV-2 viruses 
sequenced by the end of that month. During July of 2021, symptomatic 
infections were detected in 94 of 16,492 fully vaccinated workers and 
31 of 1,895 unvaccinated workers. Attack rates in July of 2021 were 5.7 
per 1,000 fully vaccinated workers and 16.4 per 1,000 unvaccinated 
workers.
    In Finland, a Delta variant infection from a hospitalized patient 
spread throughout the hospital and to three primary care facilities, 
infecting 103 individuals, including 45 healthcare workers 
(Hetem[auml]ki et al., July 29, 2021). Twenty-six of the healthcare 
workers were infected at the hospital and 19 were infected at primary 
care facilities. The affected health care workers included 28 with 
direct patient contact (11 who were not fully vaccinated), 8 
unvaccinated healthcare worker students, and 9 other staff, including 
hospital cleaners and secretaries (of whom 6 were not fully 
vaccinated). According to study authors, ``There was high vaccine 
coverage among permanent staff in the central hospital, but lower for 
HCW in primary healthcare facilities. . .'' Study authors estimated 
that vaccine effectiveness against the Delta variant in healthcare 
workers was approximately 88-91%, suggesting how much more extensive 
the outbreak could have been if a high percentage of healthcare workers 
were not fully vaccinated.
    In the UK, a Delta variant infection in a healthcare worker 
resulted in an outbreak in a care home that affected 16 of 21 residents 
and 8 of 21 staff (Williams et al., July 8, 2021). One staff member was 
hospitalized. Attack rates were 35.7% in staff who were partially 
vaccinated (i.e., received their second dose of vaccine on the day that 
the index case was diagnosed with COVID-19 or had only received one 
vaccine dose) and 40% in staff who were not vaccinated.
    Recent news stories demonstrate that outbreaks affecting staff 
members are still occurring in U.S. healthcare facilities. An outbreak 
that began in August, 2021 at a Washington State nursing center 
resulted in infections in 22 staff members and 52 residents. In an 
unrelated outbreak, a nursing facility in Hawaii reported infections in 
24 employees and 54 patients (Wingate, September 24, 2021). Vaccination 
rates were reported at 64.5% of residents and 37.1% of staff in the 
Washington State facility and 91% of staff and more than 80% of 
patients at the Hawaii facility.
    COVID-19 cases were also observed in staff at ambulatory care 
settings prior to emergence of the Delta variant. Over an 11-week 
period beginning on March 20, 2020, 254 tests for SARS-CoV-2 were 
performed on employees who had potential exposures at an outpatient 
urology center in New York State (Kapoor et al., 2020). Positive test 
rates in employees correlated with rates in New York State, declining 
over time, from 26.1% in the early stage to 7.3% in the late stage of 
the study. According to study authors, the positive test results 
coincided with the implementation of infection control procedures 
(e.g., symptom screening, masking, distancing, and hygiene). Positivity 
rates were similar in administrative and clinical staff and the study 
authors concluded that ``administrative staff in an outpatient setting 
were equally--if not more--vulnerable to SARS-CoV-2 transmission when 
compared with clinical staff who were more directly exposed to 
patients.'' The study authors speculated that possible reasons for the 
findings were that clinical staff were more familiar with PPE and that 
administrative staff, especially in check-in and check-out points, tend 
to work close to each other.


c. Conclusion for Employee Impact
    The evidence described above provides examples of the impact that 
exposures from SARS-CoV-2, including those involving the Delta variant, 
have had on employees in general industry, agriculture, construction, 
maritime, and healthcare settings. It demonstrates that SARS-CoV-2 has 
spread to employees in these industries and, in many cases, infection 
was linked to exposure to infected persons at the worksite (WSDH, 
September 8, 2021; OHA, September 1, 2021; TDH, September 8, 2021; 
NCDHHS, August 30, 2021; Hawaii State, August 19, 2021; Pray et al., 
January 29, 2021; Sami et al., April 9, 2021; Suhs et al., July 23, 
2021; Gold et al., February 26, 2021; Porter et al., April 30, 2021; 
Hetem[auml]ki et al., July 29, 2021; Williams et al., July 8, 2021). 
The documentation of so many workplace clusters suggests that exposures 
to SARS-CoV-2 occur regularly in workplaces where employees come into 
contact with others. This prevalence of clusters, combined with some 
evidence that many infections occurred within the 14-day incubation 
period for SARS-CoV-2 and that exposures to infected persons outside 
the workplace were frequently ruled out, supports the proposition that 
exposures to and transmission of SARS-CoV-2 occur frequently at work. 
Multiple studies demonstrate high rates of COVID infections, illnesses, 
and fatalities in the wide range of occupations that require frequent 
or prolonged close contact with other people, indoor work, and work in 
crowded and/or poorly ventilated areas The large numbers of infected 
employees suggest that SARS-CoV-2 is likely to be present in a wide 
variety of workplaces, placing unvaccinated workers at risk of serious 
and potentially fatal health effects.
IV. Vaccines Effectively Reduce Severe Health Outcomes From and 
Transmission of SARS-CoV-2
    During the course of the SARS-CoV-2 pandemic, different variants 
have emerged with different characteristics that better enable 
transmission and potentially cause more severe outcomes. However, 
vaccines remain very effective at reducing the occurrence of COVID-19-
related severe illness, disability and death.\12\ The Delta variant is 
more transmissible than previous variants, might cause more severe 
illness than previous variants in unvaccinated people, and has led to 
hospitalization of individuals in numbers similar to those of the 
November 2020 to February 2021 surge. These changes in characteristics 
have provided a clearer realization of the continuing capacity for 
SARS-CoV-2 to present a grave danger to workers. However, it is well 
evident that even given these changed characteristics of Delta, serious 
disease and death continue to occur overwhelmingly in unvaccinated 
individuals while the vaccinated are afforded great protection.\13\
---------------------------------------------------------------------------

    \12\ A discussion of vaccination rates, as well as OSHA's 
rationale for why vaccination is a critical means of protecting 
workers from the grave danger described in this section, can be 
found in Need for the ETS (Section III.B. of this preamble).
    \13\ While mild cases of COVID-19 are included in the grave 
danger presented by COVID-19, as stated in the Healthcare ETS (see 
86 FR 32382), OSHA is focusing on the most severe health effects, 
i.e., cases requiring hospitalization and cases resulting in death, 
in this new rulemaking effort in order to prevent the gravest of 
consequences to workers.
---------------------------------------------------------------------------

a. Impact of Vaccination on Severe Health Outcomes
    There are currently three vaccines that are approved or authorized 
for the prevention of COVID-19 in the U.S.: The Pfizer-BioNTech COVID-
19 vaccine (FDA approved for ages 16 and above; authorized for ages 12 
and above), the FDA-authorized Moderna COVID-19 vaccine (authorized for 
ages 18 and above), and the FDA-authorized Janssen COVID-19 vaccine 
(also known as the Johnson & Johnson vaccine; authorized for ages 18 
and above.) Pfizer-BioNTech and Moderna are mRNA vaccines that require 
two primary series doses administered three weeks and one month apart, 
respectively. Janssen is a viral vector vaccine administered as a 
single primary vaccination dose (CDC, September 15, 2021). The vaccines 
were shown to greatly exceed minimum efficacy thresholds in preventing 
COVID-19 in clinical trial participants (FDA, December 11, 2020; FDA, 
December 18, 2020; FDA, February 26, 2021). Data from clinical trials 
for all three vaccines and observational studies for the two mRNA 
vaccines clearly establish that fully vaccinated persons have a greatly 
reduced risk of SARS-CoV-2 infection compared to unvaccinated 
individuals. This includes severe infections requiring hospitalization 
and those resulting in death. For more information about the 
effectiveness of vaccines as of late Spring 2021, see 86 FR 32397, 
which OSHA hereby includes in the record for this ETS.\14\

    \14\ This adoption includes the citations in the referenced 
section of the Healthcare ETS, which are also included in the docket 
for this ETS.
---------------------------------------------------------------------------

    Vaccines remain highly effective against hospitalization and death. 
A study evaluating vaccine effectiveness at preventing hospitalization 
among those with SARS-CoV-2 infections in New York found that 
effectiveness did not change from May 3 to July 25, 2021 as the Alpha 
variant gave way to the Delta variant (91.9-96.2% range; Rosenberg et 
al., August 27, 2021). Grannis et al. used data from 187 hospitals in 
nine states from June to August 2021 to evaluate the efficacy of 
vaccines against hospitalization when Delta had emerged as the 
predominant variant causing SARS-CoV-2 infections (September 17, 2021). 
This study found that vaccines were 89% effective at preventing 
hospitalization in individuals aged 18 to 74. Similarly, vaccines were 
also found to be 89% effective in preventing hospitalization in a study 
collecting data from five Veteran Affairs Medical Centers from July 1 
to August 6, 2021, a time when most transmission was attributed to the 
Delta variant (Bajema et al., September 10, 2021).
    Two other studies found that, although the level of protection 
provided by vaccination has decreased somewhat with the emergence of 
the Delta variant, vaccines continue to provide high levels of 
protection against hospitalization. In a U.S. study, researchers found 
that while the Moderna and Janssen vaccines mostly maintained their 
effectiveness at preventing hospitalization (going from 93% to 92% 
after more than 120 days post-vaccination and 71% to 68% after more 
than 28 days post-vaccination, respectively) from March to August 2021, 
the effectiveness of the Pfizer-BioNTech vaccine at preventing those 
severe outcomes decreased from 91% to 77% after more than 120 days 
post-vaccination (Self et al., September 17, 2021). An Israeli study on 
infections documented between July 11 and July 31, 2021 found a 
significant decrease in vaccine efficacy for the Pfizer-BioNTech 
vaccine against severe outcomes in relation to when an individual was 
vaccinated, but the absolute difference was much less than what was 
observed in the U.S. study (e.g., 98% effective for 40-59 year olds 
vaccinated in March versus 94% effective for those in the same age 
group who were vaccinated in January) (Goldberg et al., August 30, 
2021).
    Vaccines also remain extremely effective at preventing death. A UK 
study evaluated the effectiveness of the Pfizer-BioNTech vaccine 
against death and found it to be 96.3% effective against the Alpha 
strain and 95.2% protective against the Delta strain (Andrews et al., 
September 21, 2021). Two Israeli studies, Haas et al. and Saciuk et 
al., performed during time periods where Alpha was predominant, found 
the Pfizer-BioNTech vaccine to be 96.7% and 91.1% effective,


respectively, against death (Haas et al., May 15, 2021; Saciuk et al., 
June 25, 2021). A California study found that the Moderna vaccine was 
97.9% effective against death (Bruxvoort et al., September 2, 2021). A 
study on patients served by the Veterans Health Administration found 
that Pfizer-BioNTech and Moderna vaccines provided 99% effectiveness 
against death (Young-Xu et al., July 14, 2021).
    The risks of hospitalization and death appear to have increased for 
unvaccinated individuals since the Delta variant became a common source 
of infections. A study of Los Angeles County SARS-CoV-2 infections 
found that vaccinations reduced hospitalization risk by a factor of 10 
on May 1, 2021, when the Alpha variant was dominant, but that the risk 
of hospitalization was even more greatly reduced (by a factor of 29.2) 
on July 25, 2021, when the Delta variant was dominant (Griffin et al., 
August 27, 2021). This difference suggests both that vaccines continue 
to provide a high level of protection against disease that results in 
hospitalization and that risk has increased for those who are 
unvaccinated. Similar increased risk for unvaccinated individuals was 
reported in a study that evaluated hospitalization and death data from 
13 U.S. jurisdictions between June 20 and July 17, 2021, a period when 
the Delta variant gained prominence (Scobie et al., September 17, 
2021). For unvaccinated 18 to 49 year olds, the risk of hospitalization 
was 15.2 times greater, and the risk of death was 17.2 times greater, 
than the risks for vaccinated people in the same age range. For 
unvaccinated 50 to 64 year olds, the risk of hospitalization was 10.9 
times greater, and the risk of death was 17.9 times greater, than for 
those who are vaccinated. These studies illustrate that vaccination is 
an extremely effective control measure to minimize severe outcomes 
resulting from Delta variant infections.
b. Impact of Vaccination on Infection and Transmission
    Vaccines continue to provide robust protection for vaccinated 
individuals against SARS-CoV-2 infections, even though several studies 
indicate that vaccine efficacy against infection may have decreased 
somewhat with the emergence of the Delta variant (Fowlkes et al., 
August 27, 2021; Rosenberg et al., August 27, 2021; Nanduri et al., 
August 27, 2021; Seppala et al., September 2, 2021; Bernal et al., 
August 12, 2021). For example, vaccination was observed to reduce the 
risk of infection by a factor of 8.4 on May 1, 2021, when the Alpha 
variant was predominant in Los Angeles county (Griffin et al., August 
27, 2021). However, the level of protection had fallen to a factor of 
4.9 by July 25, 2021, when Delta made up 88% of infections in the 
county. The findings from this study indicate that while vaccines 
maintain robust protection against severe outcomes, protection against 
infection has fallen with the increased circulation of the Delta 
variant. A broader study using data from 13 U.S. jurisdictions had 
similar findings, observing that the protection vaccines afforded 
against infection decreased from a factor of 11.1 (i.e., vaccinated 
people were 11.1 times less likely than unvaccinated people to become 
infected) between April 4 and June 19, 2021, to a factor of 4.6 between 
June 20 and July 17, 2021 (Scobie et al., September 17, 2021). An 
additional study noted, however, that the decrease in vaccine 
protectiveness against symptomatic infection from the Delta variant 
could be due to the waning of immunity specifically in older 
populations. Andrews et al. (September 21, 2021) found that while the 
Pfizer-BioNTech vaccine effectiveness decreased from 94.1% to 67.4% in 
those 65 years old and older, vaccine effectiveness for those 40 to 64 
years old only decreased from 92.9% to 80.6%.
    While infections themselves do not normally result in serious 
illness for those who are vaccinated, evidence shows that vaccinated 
individuals who become infected with the Delta variant can transmit the 
disease more easily to others than with previous variants. This 
development poses a great concern for the unvaccinated, who generally 
do not have the protections against severe outcomes that vaccination 
affords. Before Delta, vaccinated individuals were shown to have lower 
estimated viral loads when infected than those who were unvaccinated, 
which suggested that infected vaccinated individuals were likely not a 
major concern for transmission (Levine-Tiefenbrun et al., March 29, 
2021). Transmission studies prior to the emergence of Delta appear to 
bear this out. A Scottish study performed during a time period when the 
Alpha variant was predominant in the region, showed that a fully 
vaccinated individual was 3.2 times less likely than an unvaccinated 
individual to transmit the virus to unvaccinated family members (Shah 
et al., September 10, 2021; supplementary appendix). A population-based 
study from the Netherlands found that vaccination decreased secondary 
transmission to household members from 31% to 11% (de Gier et al., 
August 5, 2021). Additionally, a study from the UK found that household 
transmission decreased by as much as 50% when the infected individual 
was vaccinated (Harris et al., June 23, 2021).
    More recent research suggests that the Delta variant may have 
reduced the level of protection vaccination affords against 
transmission of the virus to others, but still significantly reduces 
transmission risk in comparison to infected unvaccinated individuals. A 
UK study found that fully vaccinated individuals infected by the Delta 
variant are able to transmit the virus to both vaccinated and, to a 
greater degree, unvaccinated persons (Singanayagam et al., September 6, 
2021). Still, the rate at which transmission to unvaccinated 
individuals occurred was nearly double the rate of transmission to 
vaccinated individuals (35.7% compared to 19.7%). Similarly, Eyre et 
al., (September 29, 2021) found that during the predominance of Alpha, 
full vaccination with the Pfizer-BioNTech vaccines resulted in a 
significant reduction in transmission to others (an adjusted Odds Ratio 
(aOR) of 0.18, meaning that being unvaccinated increased the odds of 
transmission by over five times). With the rise of the Delta variant, 
that reduction in transmission to others was less than with the Alpha 
variant, but still significantly more than for unvaccinated individuals 
(aOR of 0.35, meaning that being unvaccinated increased the odds of 
transmission by almost three times).
    The greater ability for vaccinated individuals to transmit the 
Delta variant of SARS-CoV-2 to others (compared to previous variants) 
appears to be linked to the generation of similar viral loads (as 
estimated by Ct threshold) in the vaccinated compared to the 
unvaccinated (Ct threshold is the number of RT-PCR cycles that need to 
be run in order to amplify the RNA enough to be detected--fewer cycles 
means a greater initial amount of virus was collected) (Singanayagam et 
al., September 6, 2021). This observation has been made in several 
studies. A study from Israel observed that viral loads among those 
infected with the Delta variant were only decreased in people who had 
been vaccinated recently (within the past two months) or in those who 
had recently received a booster dose (Levine-Tiefenbrun et al., 
September 1, 2021). In a study of SARS-CoV-2 infections in Los Angeles 
County, performed when the Delta variant was predominant, vaccination 
status did not appear to affect the estimated viral loads, suggesting 
that infected individuals who are vaccinated


may be just as likely to transmit the virus (Griffin et al., August 27, 
2021). Additionally, estimated viral loads did not appear to be 
significantly different with respect to vaccination status in a 
Wisconsin study (Riemersma et al., July 31, 2021). Regardless of viral 
loads in vaccinated and unvaccinated individuals, the fact remains 
clear that unvaccinated people pose a higher risk of transmission to 
others than vaccinated people, simply because they are much more likely 
to get COVID-19 in the first place.
    These studies, however, appear to overstate increases in 
transmission risk from vaccinated individuals related to the Delta 
variant. From May to July 2021, UK researchers tested individuals at 
random to better characterize viral load estimates in people with 
asymptomatic as well as symptomatic infections; they found that 
vaccination was associated with a significantly lower estimated viral 
load (Elliott et al., September 10, 2021). This more comprehensive 
study (i.e., Elliott et al., September 10, 2021) may have been able to 
better characterize the course of infection and to incorporate 
vaccinated individuals whose viral loads were decreasing quickly. The 
findings in Elliott et al. are consistent with studies observing that 
viral load may fall more quickly in vaccinated individuals, resulting 
in a shorter infectious period and possibly fewer transmission events 
(Chia et al., July 31, 2021; Eyre et al., September 29, 2021).
c. Conclusion for the Impact of Vaccines
    The studies discussed above indicate that vaccines continue to 
effectively protect vaccinated individuals against SARS-CoV-2 
infections, while the risk of infection, hospitalization, and death 
increased among unvaccinated people as the Delta variant became 
predominant in the U.S. The Delta variant is even more dangerous to 
unvaccinated individuals than previous variants because of the higher 
transmission potential from both unvaccinated and vaccinated people. 
Because unvaccinated individuals are at much higher risk of severe 
health outcomes from infection with SARS-CoV-2, and also pose a greater 
transmission risk to those around them, it is critical to assure that 
as many people as possible are fully vaccinated in order to prevent 
transmission at work.
V. Coverage of OSHA's Grave Danger Finding
    Based on the information discussed above, OSHA finds that many 
unvaccinated workers across the U.S. economy are facing a grave danger 
of severe health effects or death from exposure to SARS-CoV-2. Fully 
vaccinated workers are not included in this grave danger finding 
because, as described throughout this section, those who are fully 
vaccinated are much better protected from the effects of SARS-CoV-2 
and, in particular, the most severe effects, than are those who are 
unvaccinated.\15\ Beyond that, OSHA's grave danger determination 
exempts several categories of workers based on characteristics of their 
work or workplace: (1) Workers who do not report to a workplace where 
other individuals are present or who telework from home; and (2) 
workers who perform their work exclusively outdoors. The basis for 
these exemptions is explained below. In this section, OSHA also 
addresses the basis for OSHA's grave danger finding for workers who are 
unvaccinated yet had a prior COVID-19 infection, and explains the 
Agency's more nuanced grave danger finding in the healthcare industry.
---------------------------------------------------------------------------

    \15\ The exclusion of vaccinated workers from this grave danger 
finding does not mean that vaccinated workers face no risk from 
exposure to SARS-CoV-2. The best available evidence clearly shows 
that vaccination provides great protection from infection and severe 
outcomes, but breakthrough infections do occur and vaccinated 
individuals can still transmit the virus to others. In some cases, 
the level of risk to vaccinated workers may even rise to the level 
of a significant risk, the standard OSHA must meet for promulgation 
of a permanent standard under section 6(b)(5) of the OSH Act (29 
U.S.C. 655(b)(5)).
---------------------------------------------------------------------------

a. Employees Who Telework and Employees Who Do Not Report to a 
Workplace Where Other People Are Present.
    Employees who report to workplaces where no other people are 
present face no grave danger from occupational exposure to COVID-19 
because such exposure requires the presence of other people. For those 
who work from their homes, or from workplaces where no other people are 
present (such as a remote worksite), the chances of being exposed to 
SARS-CoV-2 through a work activity are negligible. Therefore, OSHA is 
exempting those workers who do not come into contact with others for 
work purposes from its grave danger finding as well as the scope of the 
ETS (for more information, see the Summary and Explanation for Scope 
and Application, Section VI.B. of this preamble).
b. Employees Who Work Exclusively Outside
    Employees who work exclusively outside face a much lower risk of 
exposure to SARS-CoV-2 at work, because their workplaces typically do 
not include any of the characteristics that normally enable 
transmission to occur (e.g., indoors, lack of ventilation, crowding). 
Bulfone et al. attributed the lower risk of transmission in outdoor 
settings (i.e., open air or structures with one wall) to increased 
ventilation with fresh air and a greater ability to maintain physical 
distancing (November 29, 2020). While the best available evidence 
firmly establishes a grave danger in indoor settings, the CDC has 
stated that the risk of outdoor transmission is ``low'' (CDC, September 
1, 2021) and OSHA is unable to establish a grave danger in outdoor 
settings from exposure during normal work activities.
    OSHA recognizes that outdoor transmission has been identified in a 
few specific incidents (e.g., 2 of 7,324 cases, Qian et al., October 
27, 2020). However, general reviews of transmission studies that 
include large-scale and high-density outdoor gatherings indicate that 
indoor transmission overwhelmingly is responsible for SARS-CoV-2 
transmission. Additionally, the lack of evidence tied to specific case 
studies illustrating outdoor transmission in comparison to the bevy of 
case studies on indoor transmission makes it difficult to support a 
conclusion that outdoor transmission rises to the level of a grave 
danger.
    Bulfone et al. reviewed a collection of SARS-CoV-2 studies that 
evaluated infections in outdoor and indoor settings (November 29, 
2020), and found that transmission is significantly less likely to 
occur in outdoor settings than in indoor settings. The studies overall 
found that the risk of outdoor transmission was less than 10% of the 
risk of transmission in indoor settings, with three of the studies 
concluding risk was 5% or less of the risk of transmission in indoor 
settings. While acknowledging significant gaps in knowledge, the 
authors of a different study suggested that increases in transmission 
related to large events such as the Sturgis motorcycle rally may be 
related to lack of local efforts to prevent transmission indoors (e.g., 
requiring the wearing of masks, closing indoor dining), rather than the 
outdoor setting for the rally (Dave et al., December 2, 2020). In 
contrast, transmission rates did not increase as expected following the 
Summer 2020 protests on racial injustice. This outcome was attributed, 
in part, to participants having been less likely to enter indoor 
commercial establishments.


    Weed and Foad (September 10, 2020) found that transmission of SARS-
CoV-2 related to large scale outdoor gatherings could be largely 
attributed to individual behaviors related to that event, such as 
communal travel and indoor congregation at other facilities (e.g., 
restaurants, shared accommodations), rather than to the time spent 
outdoors at those gatherings. Similarly, a Public Health England 
evaluation of the literature on SARS-CoV-2 and surrogate respiratory 
viruses (December 18, 2020) also concluded that when transmission does 
occur at outdoor events, outdoor activities were mixed with indoor 
setting use. Public Health England concluded that the vast majority of 
transmission happens in indoor settings, with very little evidence for 
outdoor transmission.
    A systemic review of SARS-CoV-2 clusters identified 201 events 
through May 26, 2020 (Leclerc et al., April 28, 2021), only 4 of which 
occurred at predominantly outdoor settings. For those 4 clusters, the 
authors noted that they were not able to evaluate specific transmission 
events and attributed it to local health agencies being overwhelmed by 
the pandemic. OSHA notes that the designations of settings in this 
study are somewhat generic, as outdoor construction sites will often 
have indoor locations, such as mobile offices, or locations with 
reduced airflow, such as areas with a roof or ceiling and two or more 
walls. Regardless, this study illustrates the comparable abundance of 
evidence available to evaluate SARS-CoV-2 transmission in indoor 
settings versus outdoor settings.
    Cevik et al. (August 1, 2021) reviewed studies on the transmission 
dynamics of SARS-CoV-2 infections from large scale, contact-tracing 
studies. The authors recommended that, based on the evidence that 
outdoor transmission dynamics resulted in significantly fewer 
infections than in indoor settings, public health entities should 
greatly encourage use of outdoor settings. The researchers highlighted 
a study by Nishiura et al. (April 16, 2020), who evaluated 110 cases in 
Japan at the beginning of the pandemic and found that outdoor settings 
reduced transmission risk by 18.7 times and reduced the risk of super-
spreader events by 32.5 times.
    Agricultural workplace settings have experienced significant SARS-
CoV-2 infections. However, transmission in these settings is difficult 
to characterize because many jobs in this sector include both outdoor 
and indoor activities. Miller et al. (April 30, 2021) evaluated an 
outbreak among farmworkers in Washington State. The researchers found 
that 28% of workers with predominantly indoor tasks where they were 
unable to maintain physical distance were infected, compared to 6% of 
workers who performed predominantly outdoors tasks in the orchards. 
Conversely, a study on farmworkers in Monterey County, California found 
a significant correlation between evidence of infection and individuals 
who worked in the fields as opposed to indoor work (Mora et al., 
September 15, 2021). The paper noted that infections were predominant 
in individuals who lived in crowded conditions, commuted together to 
the fields, and spoke at home in indigenous languages, which is 
important as written health messages are often not available in all 
worker languages. These papers cannot identify where or when infections 
occurred in order to discern causation. The associations observed may 
indicate that SARS-CoV-2 infections may be more related to aspects 
related to indoor exposures outside of the work activities (e.g., 
crowded living conditions) or potentially overlooked indoor aspects 
connected to outdoor work (e.g., shared commuting).
    Several studies discussed below in more detail have evaluated 
outdoors on-field transmission from infected participants during 
football, soccer, and rugby matches. These events include repeated 
close physical contact between players, without PPE or physical 
distancing, over the course of fairly long events, with increased 
exertion leading to greater respiratory effort and production of 
respiratory droplets. These events also include opposing cohorts who 
only interact during on-field activities. Therefore, these studies 
provide some evidence for the low likelihood of outdoor transmission in 
other workplace activities greatly impacted by the pandemic, such as in 
construction.
    Mack et al. (January 29, 2021) detailed the National Football 
League's complex program to assess and prevent transmission, which 
included devices that recorded distance and duration of interactions 
with others, for the purpose of improving identification of individuals 
with high-risk exposures. Although 329 positive cases were identified 
among roughly 11,400 players and staff, there were no reported cases of 
on-field transmission by infected players. The results led the NFL to 
focus more on reducing transmission in indoor settings, including 
transportation.
    Egger et al. (March 18, 2021) reviewed three soccer matches 
involving 18 players who had SARS-CoV-2; one match involved a team 
where 44% of the players were infected. Video analysis was used to 
determine the type of contact between players, such as contact to face 
or hand slaps. None of the existing cases were associated with on-field 
play and no secondary transmission from on-the-field contacts was 
observed. Jones et al. (February 11, 2021), evaluated four rugby Super 
League matches involving eight players who were found to be infected 
with SARS-CoV-2. Using video footage and global positioning data, the 
researchers were able to identify 28 players as high-risk contacts with 
the infected players. These high-risk players together had as many as 
32 tackles and were within two meters of infected players as often as 
121 times during the four matches. Of the 28 players noted as high-risk 
contacts, one became infected with SARS-CoV-2. However, researchers 
determined that the transmission resulted from internal team outbreaks 
and not from exposure on the field.
    OSHA acknowledges that the risk of transmission of SARS-CoV-2 in 
outdoor settings is not zero, and that there may be some low risk to 
workers performing general tasks exclusively in outdoor settings. 
However, where studies have been able to differentiate between indoor 
and outdoor exposures, they indicate that indoor exposures are the much 
more significant drivers of SARS-CoV-2 infections. Therefore, the best 
available evidence at this time does not provide OSHA with the 
information needed to establish SARS-CoV-2 as a grave danger for 
general work activities in outdoor settings (see Int'l Union, United 
Auto., Aerospace, & Agr. Implement Workers of Am., UAW, 590 F. Supp. at 
755-56, describing a ``grave danger'' as a risk that is more than 
``significant''). Therefore, OSHA has excluded employees who work 
exclusively outdoors from the scope of this ETS (see the Summary and 
Explanation for Scope and Application, Section VI.B. of this preamble).
c. Employees in Healthcare
    Because OSHA issued a separate grave danger determination several 
months ago for some healthcare workers, some explanation of how its 
current finding applies to healthcare workers is necessary. In June 
2021, OSHA issued its Healthcare ETS (86 FR 32376) after determining 
that some healthcare workers faced a grave danger of infection from 
SARS-CoV-2. This grave danger determination, along with the protections 
of the Healthcare ETS, applied to healthcare and healthcare support 
workers in settings where


people with suspected or confirmed cases of COVID-19 are treated, and 
was based on the increased potential for transmission of the virus in 
such settings (see 86 FR 32411-32412). These workers are currently 
covered by the protections of the Healthcare ETS (29 CFR 1910.502). 
OSHA does not have data to demonstrate that unvaccinated workers in 
settings covered by the Healthcare ETS face a grave danger from SARS-
CoV-2 when the requirements of that standard are followed. However, if 
the Healthcare ETS were no longer in effect, OSHA would consider the 
workers who were covered by it, and who remain unvaccinated, to be at 
grave danger for the reasons described in this ETS.
    OSHA's new finding of grave danger applies to healthcare and 
healthcare support workers who are not covered by the Healthcare ETS, 
to the extent they remain unvaccinated. In this ETS, as discussed in 
this section, OSHA has made a broader determination of grave danger 
that applies to most unvaccinated workers, regardless of industry. 
OSHA's current finding of grave danger supporting this ETS does not 
depend on whether a workplace is one where people with suspected or 
confirmed COVID-19 are expected to be present. Therefore, the finding 
of grave danger applies to unvaccinated workers in healthcare settings 
that are not covered by 29 CFR 1910.502 to the same extent it applies 
to unvaccinated workers in all other industry sectors.
d. Employees Who Were Previously Infected With SARS-CoV-2
    OSHA has carefully evaluated the effectiveness of previous SARS-
CoV-2 infections in providing protection against reinfection. This 
section provides a detailed description of the current scientific 
information in order to ascertain what the best available scientific 
evidence on this topic indicates regarding the risk to individuals with 
previous COVID-19 infections from exposure to SARS-CoV-2. While the 
agency acknowledges that the science is evolving, OSHA finds that there 
is insufficient evidence to allow the agency to consider infection-
acquired immunity to allay the grave danger of exposure to, and 
reinfection from, SARS-CoV-2.
    To determine whether employees with infection-induced immunity from 
SARS-CoV-2 (i.e., those who were infected with SARS-CoV-2 but have not 
been vaccinated) face a grave danger, OSHA reviewed the scientific 
evidence on the protective effects of vaccine-induced SARS-CoV-2 
immunity versus infection-induced immunity. Individual immunity to any 
infectious disease, including SARS-CoV-2, is achieved through a complex 
response to exposure by the immune system. This response consists of 
disease-specific antibody production guided and augmented by certain 
types of immune cells, such as T and B cells, which work together to 
neutralize or destroy the disease-causing agent. Immune responses to 
viruses like SARS-CoV-2 can be measured in several ways. For instance, 
blood serum can be taken and exposed to specific proteins found on the 
SARS-CoV-2 virus, in order to measure the presence of antibodies in the 
blood. Another antibody test, the neutralization test, measures the 
ability of the antibodies present in a serum to neutralize infectivity 
and prevent cells from being infected. T cell immunity can be measured 
using techniques that target a specific biomolecule that is specific to 
SARS-CoV-2.
    A considerable number of individuals who were previously infected 
with SARS-CoV-2 do not appear to have acquired effective immunity to 
the virus (Psichogiou et al., September 13, 2021; Wei et al., July 5, 
2021; Cavanaugh et al., August 13, 2021). The level of protection 
afforded by infection-induced immunity appears to depend on the 
severity of individuals' infections. In a study from Greece, 
immunogenicity was compared between healthcare workers who were 
vaccinated with Pfizer-BioNTech and unvaccinated patients who acquired 
a natural infection (Psichogiou et al., September 13, 2021). The 
researchers found that the immune response in unvaccinated individuals 
correlated to the severity of their disease. Fully vaccinated 
healthcare workers had immune responses (measured as antibody levels 
specific to SARS-CoV-2) that were 1.3 times greater than patients who 
had critical cases of COVID-19 cases, 2.5 times greater than patients 
who had moderate to severe cases, and 10.5 times greater than patients 
who had asymptomatic/mild illnesses. Similarly, another study found 
that 24.0% (1,742 of 7,256) of individuals who had a previous SARS-CoV-
2 infection were seronegative (i.e., did not produce antibodies in 
response to the virus), suggesting that the previous infection provided 
insufficient protection against future infection (Wei et al., July 5, 
2021). Individuals who were seronegative were typically older, had 
lower viral burdens when infected, and were more likely to be 
asymptomatic. The authors posited that the immunity of those who were 
seropositive (i.e., did produce antibodies in response to the virus) 
would provide some measure of protection, but that these individuals 
would benefit from a vaccination booster. This position appears to be 
validated by a study that compared the reinfection rates of individuals 
in Kentucky based on their post-recovery vaccination status (Cavanaugh 
et al., August 13, 2021). Unvaccinated individuals with previous 
infection were found to be 2.3 times more likely to be reinfected than 
those who were vaccinated after their prior infection. These studies 
demonstrate not only that those with milder infections may not be 
protected against future infection, but that it is difficult to tell, 
on an individual level, which individuals might have had prior 
infections that conveyed protection equivalent to that provided by 
vaccination.
    A number of other studies indicate that fully vaccinated 
individuals may be better protected against future infection than those 
with previous infections. A study in Massachusetts concluded that the 
immunity conveyed from a previous SARS-CoV-2 infection was effectively 
equivalent to the immunity of an uninfected individual who has had only 
one dose of an mRNA vaccine (Naranbhai et al., October 13, 2021). The 
authors found that fully vaccinated individuals have an immune response 
(i.e., antibodies and neutralization) well above the levels observed in 
unvaccinated, previously-infected individuals. German researchers found 
that individuals who were fully vaccinated with Pfizer-BioNTech had a 
significantly greater immune response (as measured by antibody levels) 
than unvaccinated individuals who had infections, concluding that 
vaccination would be needed for those unvaccinated individuals to have 
similar protection against infection (Herzberg et al., June 13, 2021). 
Similarly, a Dutch study observed that vaccination greatly improved the 
immune response (as measured by antibodies and virus-specific T cells) 
of individuals who had recovered from COVID-19 (Geers et al., May 25, 
2021). Planas et al. (August 12, 2021) also noted that immune response 
(as measured by neutralization) to the Alpha, Beta, and Delta 
(B.1.617.2) variants in unvaccinated, previously-infected individuals 
was considerably less than the immune response in individuals five 
weeks after their second Pfizer-BioNTech dose. When unvaccinated, 
previously-infected individuals were vaccinated, their immune response 
(as measured by neutralization) increased by more than an order of 
magnitude. Likewise, Wang



et al. (July 15, 2021) found that the immune response (as measured by 
neutralization) of those with previous SARS-CoV-2 infection increased 
by more than an order of magnitude against Alpha (B.1.1.7), Beta 
(B.1.351), Iota (B.1.526), and Gamma (P.1) variants when they were 
vaccinated. These studies show that infection-induced immunity may not 
equal the protection afforded by vaccination and that vaccination 
greatly improves the immune response of those who were previously 
infected.
    The aforementioned studies indicate that immunity acquired through 
infection appears to be less protective than vaccination. There are 
also a number of epidemiological studies that provide some evidence 
that infection-acquired immunity has the potential to provide a 
significant level of protection against reinfection. As OSHA discusses 
in greater detail below, these studies suffer from methodological 
limitations that render them inconclusive about the level of immunity 
conferred by infection, and therefore OSHA is unable to establish that 
such immunity eliminates grave danger. This determination is based in 
three parts.
    First, the epidemiological literature OSHA reviewed generally 
suffers from selection bias to a degree that it serves as an unreliable 
basis on which to reach a robust conclusion on whether previous 
infection removes workers from grave danger. In general, the studies 
described below do not account for people who had mild COVID-19 
infections, leading to study findings regarding the level of protection 
afforded by prior infection that are not generally applicable. Second, 
the tests employed in the studies are being used in ways that they were 
not originally designed to be employed. These tests are powerful tools, 
but there are limitations to their use in determining if a specific 
individual is, in fact, protected from the grave danger of SARS-CoV-2. 
Particularly problematic is the lack of established thresholds to 
determine full protection from reinfection or even a standardized 
methodology to determine infection severity or immune response. Thus, 
while these studies broadly establish some increase in protectiveness 
against SARS-CoV-2 among the studied populations, they as yet are 
unable to provide a reasonable degree of certainty on whether the 
degree of protection afforded any particular individual from their 
prior infection is sufficient to eliminate the grave danger from 
reinfection (see Milne, et al., October 21, 2021.) Third, while the 
research methodology itself creates difficulties in the context of 
OSHA's grave danger inquiry, the implications of trying to apply 
investigative research methodology to clinical practice are even more 
challenging. The need for the development of standardized methods and 
criteria for establishing sufficient immunity preclude the application 
of the studies' findings to robust and reliable clinical practice. 
These three rationales for OSHA's finding are described in more detail 
below.
    Several epidemiological studies used previous RT-PCR positive cases 
to define previous infections (Hansen et al., March 27, 2021; Pilz et 
al., February 11, 2021; Vitale et al., May 28, 2021; Pouwels et al., 
October 14, 2021; Braeye et al., September 15, 2021; Hall et al., April 
17, 2021). RT-PCR tests, particularly in the beginning of the pandemic, 
were given high priority to discern who seeking medical care was, in 
fact, infected. For instance, the progression of testing from medical 
needs to more of a community perspective is illustrated in Denmark 
(Vrangbaek et al., April 29, 2021). Denmark, considered one of the gold 
standard countries for its comprehensive testing program, missed five 
infections for every one it identified in the spring of 2020 (Espenhaim 
et al., August 22, 2021). Hansen et al. (March 27, 2021) depended 
greatly on these first surge infection definitions to determine that 
survivors had protection of 80.5% effectiveness during the second surge 
in Denmark from September through December, 2020. By only noting RT-PCR 
positives from the spring when testing was limited and highly focused 
on health care needs, it seems apparent that the study excluded many 
less severe cases (which are less likely to result in an effective 
immune response against reinfection), leading to results that may 
suggest greater protection is afforded by infection than in actuality. 
Even by December of 2020, it appears Denmark's gold standard 
comprehensive testing approach was only able to capture roughly half of 
all infections. Similar systemic undercounts have also been determined 
to be true in the United States where approximately three out of four 
infections have never been reported (CDC, July 27, 2021b).
    It is important to recognize that RT-PCR testing was not 
implemented to find every infection, but was used instead to assist in 
determining when medical and community interventions were necessary. 
Infections without symptoms or with mild symptoms likely would not 
require medical intervention and, therefore, would likely not be 
identified via testing. The absence of this population that is more 
vulnerable to reinfection, in these studies, undercuts their usefulness 
in OSHA's grave danger analysis, because they may overestimate the 
protectiveness of immunity acquired through infection.
    Several other studies in regions less known for their sampling 
approach than Denmark also were heavily dependent on early, limited 
pandemic RT-PCR testing. An Austrian study found a roughly ten-fold 
decrease in reinfection in survivors of reported infections from 
February to April 30, 2020 in comparison with the general public (Pilz 
et al., February 11, 2021). The authors noted that ``infections in the 
first wave are likely to have been far more common than the documented 
ones'' and referred to their results as a ``rough estimate.'' 
Researchers at the Cleveland Clinic also found a reduced rate of 
reinfection in those who had a reported previous infection compared 
with those with no prior infection (13.8% infection rate for those 
previously uninfected and 4.9% infection rate for those previously 
infected), but noted that testing was limited in that the ``Cleveland 
Clinic did not test asymptomatic patients unless they were admitted to 
hospital or undergoing a procedure/surgery'' (Sheehan et al., March 15, 
2021). These criteria for testing create uncertainty in determining the 
level of effectiveness previous infection provides against SARS-CoV-2 
because many individuals with asymptomatic infections would not have 
been tested. Similar issues are also found in studies on populations in 
Italy, Belgium, and the UK (Vitale et al., May 28, 2021; Braeye et al., 
September 15, 2021; Pouwels et al., October 14, 2021).
    To avoid the well-known problems with RT-PCRs defining previous 
infection, other studies have defined previous infection as testing 
positive for antibodies specific for SARS-CoV-2 (Lumley et al., 
February 11, 2021; Abu-Raddad et al., April 28, 2021; Hall et al., 
April 17, 2021). As noted above, previous infection does not 
necessarily result in a seropositive outcome; one study indicated that 
nearly a quarter (24%) of those infected with SARS-CoV-2 subsequently 
showed no sign of an immune response in SARS-CoV-2-specific antibody 
testing (Wei et al., July 5, 2021). Therefore, studies only considering 
seropositive individuals are in essence studying only the individuals 
most likely to have protection from reinfection. Lumley et al. 
(February 11, 2021) found that those having a seropositive response had 
almost an order of magnitude fewer infections (e.g., 0.11 adjusted 
incidence rate ratio). Likewise, Abu-Raddad et al. (April 28,


2021) found that seropositive individuals were reinfected less (0.7%) 
during their study period in comparison to seronegative individuals 
(3.09%). In addition to the bias associated with using antibodies to 
determine previous infection, the authors also noted that there may 
have been issues with being able to document cases with mild or no 
symptoms.
    Hall et al. (April 17, 2021) cast a wider net by defining previous 
infection to include both positive RT-PCR tests and seropositivity. The 
researchers found that those who were considered previously infected 
had an 84% lower risk of infection compared to those who were 
unvaccinated with no record of infection. While the study does attempt 
to capture as many previously-infected individuals as possible, this 
does not actually address the weaknesses of each method. Those with 
less severe infections were less likely to have sought out or been able 
to get an RT-PCR test during the first surge, which is when an 
overwhelming number of the previous infections were recorded in this 
study (March through May, 2020). Additionally, the less severe 
infections that are most likely underrepresented in the study appear to 
be the ones that are less likely to produce seropositivity. Shenai et 
al. (September 21, 2021) pooled several studies with the above issues 
and concluded that immunity acquired through a previous infection from 
SARS-CoV-2 may be as protective as, or more protective than, the 
immunity afforded by vaccination to an individual without previous 
infection. However, authors of several of those underlying studies used 
in the analysis noted that their studies were limited by not having the 
capability to fully account for asymptomatic infections (the 
aforementioned Lumley et al., July 3, 2021; Gazit et al., August 25, 
2021; Shrestha et al., June 19, 2021). As noted earlier, infection 
severity appears to be correlated with the robustness of immunity 
acquired through that infection, so the failure to account for 
asymptomatic infections may mean that this finding is related to the 
protection afforded by more severe disease. While pooled analyses can 
be utilized to make powerful observations, those observations are 
highly dependent upon the underlying studies not sharing the same 
methodological weakness which, in this case, was the studies' exclusion 
of asymptomatic infections.
    Moreover, while the evidence suggests that severe infection may 
provide significant protection against reinfection in some cases (Milne 
et al., October 21, 2021), the level of protection cannot be determined 
on an individual basis. The studies discussed above are based on tests 
that show only whether a person was or was not infected and provide no 
information about the severity of the infection. Because the studies 
are likely biased towards those who had a relatively serious infection, 
their findings cannot be generalized to all individuals with prior 
infections.
    RT-PCR and antibody testing are powerful tools with many clinical 
and research applications. However, the application of these tools 
cannot determine what degree of protection a particular individual has 
against SARS-CoV-2 without a great deal of additional study concerning 
thresholds establishing individual immunity. Therefore, these tools are 
not yet able to assist OSHA in making more nuanced findings about which 
workers who had COVID-19 previously are at grave danger. There is no 
established threshold to determine full protection from reinfection or 
a standardized methodology to determine infection severity or immune 
response. Studies use Ct threshold to approximate viral loads and infer 
disease severity, but that metric depends on many variables (e.g. time 
of collection during infection, quality of collection, handling of 
sample, specifics of the test protocol and materials, precision in 
performing the protocol) that are often of far less importance when it 
is used as a crude diagnostic to determine the presence of an 
infection. In other words, it is reasonable to say that the lower the 
Ct count, the greater the likelihood that an individual is at a lower 
reinfection risk; however, the Ct count is greatly dependent on the RT-
PCR test used, and how different laboratories may run that test, which 
cannot be discerned. Similarly, research needs to be done to better 
identify the minimum protective threshold of anti-SARS-CoV-2 serum 
neutralizing antibodies (Milne et al., October 21, 2021). Thus, these 
studies currently do not allow OSHA to determine, with a reasonable 
degree of certainty, how much protection employees with prior 
infections have against reinfection.
    Furthermore, while the research methodology itself raises 
challenges in making the grave danger determination, the implications 
of trying to apply investigative research methodology to clinical 
practice are even more difficult. The lack of standardized methods and 
standardized measures for immunity preclude their application to robust 
and reliable clinical practice. One major drawback discussed above is 
that, in contrast to vaccine studies where researchers know who was 
vaccinated with a standardized dosing regime, scientific inquiries 
likely will not be able to identify most individuals who were infected, 
the degree of disease experienced for those with a confirmed infection, 
and the immunity against reinfection. As of October 18, 2021, several 
RT-PCR assays have been authorized without standardization or 
assessment with respect to measuring disease severity (FDA, October 18, 
2021). As noted above, the use of the Ct threshold to approximate viral 
loads and infer disease severity is unreliable. As the FDA notes, the 
same is true about antibody tests, which are considered to be poor 
indicators for individuals to use to determine whether they are 
protected from reinfection (FDA, May 19, 2021). There are many 
different SARS-CoV-2-specific antibody tests that focus on different 
specificity. Not only are the outcomes of these tests not directly 
comparable to each other, but the specificity of these tests is not 
related to any notion of protection against reinfection. It can be 
reasonably said that a greater antibody response means a greater 
likelihood of protection against infection, but, again, the science is 
not clear what those thresholds are and whether a threshold would be 
comparable between laboratories. At this point in time, even if OSHA 
determined that some individuals with prior infections are not at grave 
danger from exposure to SARS-CoV-2, there is no agreement on what 
indicators of infection might be sufficient to confer this level of 
immunity or how a healthcare provider or employer could document that a 
certain level of immunity had been achieved.
    Based on the best available evidence described above, OSHA 
concludes that while some individuals who were infected with SARS-CoV-2 
may have significant protection from subsequent infections, the level 
of protection afforded by infection may be significantly impacted by 
the severity of the infection and some previously infected individuals 
may have no future protection at all. In addition, given the 
limitations of the studies described above, there is considerable 
uncertainty as to whether any given individual is adequately protected 
against reinfection. Furthermore, the level of protection, if any, 
provided by a given person's SARS-CoV-2 infection cannot be ascertained 
based on currently-available testing methods. Therefore, OSHA finds 
that the requirements of this ETS are necessary to protect unvaccinated 
individuals who had prior SARS-CoV-2 infections from the grave danger 
from exposure to SARS-CoV-2.


    OSHA recognizes that its finding regarding infection-induced 
immunity is being made in an area of inquiry that is currently on the 
``frontiers of scientific knowledge'' (Indus. Union Dep't, AFL-CIO v. 
Am. Petroleum Inst., 448 U.S. 607, 656 (1980)). For these reasons, OSHA 
finds that those who have previously been infected with SARS-CoV-2 and 
are not yet fully vaccinated are at grave danger from SARS-CoV-2 
exposure and that it is necessary to protect these workers via 
vaccination, or testing and the use of face coverings, under this 
standard. OSHA will continue to follow developments on this issue, 
however, and make appropriate adjustments to this ETS if the evidence 
warrants.
VI. Conclusion.
    OSHA finds that many employees in the U.S. who are not fully 
vaccinated against COVID-19 face a grave danger from exposure to SARS-
CoV-2 in the workplace. OSHA's determination is based on the severe 
health consequences of exposure to the virus, including death; powerful 
lines of evidence demonstrating the transmissibility of the virus in 
the workplace; and the prevalence of infections in employee 
populations.
    With respect to the grave health consequences of exposure to SARS-
CoV-2, OSHA has found that regardless of where and how exposure occurs, 
COVID-19 can result in death. Even for those who survive a SARS-CoV-2 
infection, the virus can cause serious, long-lasting, and potentially 
permanent health effects. Serious cases of COVID-19 require 
hospitalization and dramatic medical interventions, and might leave 
employees with permanent and disabling health effects. Both death and 
serious cases of COVID-19 requiring hospitalization provide independent 
bases for OSHA's finding of grave danger. The evidence is clear that 
the safe and effective vaccines authorized and/or approved for use in 
the United States greatly reduce the likelihood of these severe 
outcomes.
    The best available evidence on the science of transmission of the 
virus makes clear that SARS-CoV-2 is transmissible from person to 
person in shared workplace settings. The likelihood of transmission can 
be exacerbated by common characteristics of many workplaces, including 
working indoors, working with others for extended periods of time, poor 
ventilation, and close contact with potentially infectious individuals. 
The likelihood of transmission in the workplace is also exacerbated by 
the presence of unvaccinated workers, who are more likely than those 
who are vaccinated to be infected and transmit the virus to others. 
Every workplace SARS-CoV-2 exposure or transmission has the potential 
to cause severe illness or even death, particularly in unvaccinated 
workers. Taken together, the severe health consequences of COVID-19 and 
the evidence of its transmission in environments characteristic of the 
workplaces covered by this ETS demonstrate that exposure to SARS-CoV-2 
represents a grave danger to unvaccinated employees in many workplaces 
throughout the country.
    The existence of a grave danger to employees from SARS-CoV-2 is 
further supported by the toll the pandemic has already taken on the 
nation as a whole and the number of workers who remain unvaccinated. 
Although OSHA cannot state with precision the total number of workers 
in our nation who have contracted COVID-19 at work and became sick or 
died, COVID-19 has killed 723,205 people in the United States as of 
October 18, 2021 (CDC, October 18, 2021--Cumulative US Deaths). That 
death toll includes 131,478 people who were 18 to 64 years old, prime 
working age (CDC, October 18, 2021--Demographic Trends, Deaths by Age 
Group). OSHA estimates that there are over 26 million workers subject 
to the rule who remain unvaccinated at present and therefore are in 
grave danger. As a result of this ETS, the agency estimates that 72% of 
them will be vaccinated (see OSHA, October 2021c).
    Current mortality data shows that unvaccinated people of working 
age have a 1 in 202 chance of dying when they contract COVID-19 (CDC, 
October 18, 2021--Demographic Trends, Cases by Age Group; Demographic 
Trends, Deaths by Age Group). As of October 18, 2021, close to 45 
million people in the United States have been reported to have 
infections, and thousands of new cases were being identified daily 
(CDC, October 18, 2021--Daily Cases).One in 14 reported cases of COVID-
19 in people ages 18 to 64 becomes severe and requires hospitalization 
(CDC, October 18, 2021--Demographic Trends, Cases by Age; Total 
Hospitalizations, by Age). Moreover, public health officials agree that 
these numbers fail to show the full extent of the deaths and illnesses 
from this disease, and racial and ethnic minority groups are 
disproportionately represented among COVID-19 cases, hospitalizations, 
and deaths (CDC, December 10, 2020; CDC, May 26, 2021; Escobar et al., 
February 9, 2021; Gross et al., October 2020; McLaren, June 2020; CDC, 
October 6, 2021). Given this context, OSHA is confident in its finding 
that exposure to SARS-CoV-2 poses a grave danger to the employees 
covered by this ETS.
    The above analysis fully satisfies the OSH Act's requirements for 
finding a grave danger. Although OSHA usually performs a quantitative 
risk assessment based on extrapolations among exposure levels before 
promulgating a health standard under section 6(b)(5) of the OSH Act (29 
U.S.C. 655(b)(5)), that type of analysis is not necessary in this 
situation. OSHA has most often invoked section 6(b)(5) authority to 
regulate exposures to chemical hazards involving much smaller 
populations, many fewer cases, extrapolations from animal evidence, 
long-term exposure, and delayed effects. In those situations, 
mathematical modelling is necessary to evaluate the extent of the risk 
at different exposure levels. The gravity of the danger presented by a 
disease with acute effects like COVID-19, on the other hand, is made 
obvious by a straightforward count of deaths and illnesses caused by 
the disease, which reach sums not seen in at least a century. The 
evidence compiled above amply supports OSHA's finding that SARS-CoV-2 
presents a grave danger in American workplaces. In the context of 
ordinary 6(b) rulemaking, the Supreme Court has said that the OSH Act 
is not a ``mathematical straitjacket,'' nor does it require the agency 
to support its findings ``with anything approaching scientific 
certainty,'' particularly when operating on the ``frontiers of 
scientific knowledge'' (Indus. Union Dep't, AFL-CIO v. Am. Petroleum 
Inst., 448 U.S. 607, 655-56 (1980)). This is true a fortiori in the 
current national crisis, where OSHA must act to ensure employees are 
adequately protected from the hazard presented by the COVID-19 pandemic 
(see 29 U.S.C 655(c)(1)).The grave danger from SARS-CoV-2 represents 
the biggest threat to employees in OSHA's more than 50-year history. 
The threat applies to employees in all sectors covered by OSHA, 
including general industry, construction, maritime, agriculture, and 
healthcare. Having made the determination of grave danger, as well as 
the determination that an ETS is necessary to protect employees from 
exposure to SARS-CoV-2 (see Need for the ETS, Section III.B. of this 
preamble), OSHA is required to issue this standard to protect employees 
from getting sick or dying from COVID-19 acquired at work (see 29 
U.S.C. 655(c)(1)).

B. Need for the ETS

    This ETS is necessary to protect unvaccinated workers from the risk 
of contracting COVID-19, including its more contagious variants, such 
as the B.1.617.2 (Delta), at work. The rule protects workers through 
the most effective and efficient workplace control available: 
Vaccination. Additionally, this ETS is necessary to protect workers who 
remain unvaccinated through required regular testing, use of face 
coverings, and removal of infected employees from the workplace.
I. Events Leading to the ETS
    This section describes the evolution of OSHA's actions to protect 
employees from the grave danger posed by COVID-19 and the agency's 
reasons for issuing this ETS at this time.
a. OSHA's 2020 Actions Regarding COVID-19
    Beginning in early 2020, OSHA began to monitor the growing cases of 
the SARS-CoV-2 virus that were occurring around the country. Because 
scientific information about the disease, its potential duration, and 
ways to mitigate it were undeveloped, OSHA decided to monitor the 
situation. As noted below, OSHA subsequently issued numerous guidance 
documents advising interested employers of steps they could take to 
mitigate the hazard arising from the virus.
    Also beginning in early 2020, OSHA received numerous petitions and 
supporting letters from members of Congress, unions, advocacy groups, 
and one group of large employers urging the agency to take immediate 
action by issuing an ETS to protect employees from exposure to the 
virus that causes COVID-19 (Scott and Adams, January 30, 2020; NNU, 
March 4, 2020; AFL-CIO, March 6, 2020; Menendez et al., March 9, 2020; 
Wellington, March 12, 2020; DeVito, March 12, 2020; Carome, March 13, 
2020; SMART, March 30, 2020; Blumenthal et al., April 8, 2020; Murray 
et al., April 29, 2020; Luong, April 30, 2020; Novoa, June 24, 2020; 
Solt, April 28, 2020; Castro et al., April 29, 2020; Talbott and Adely, 
May 4, 2020; Public Citizen, March 13, 2020;


LULAC, March 31, 2020; Meuser, May 1, 2020; Raskin, April 29, 2020; 
Cartwright et al., May 7, 2020; Frosh et al., May 12, 2020; Pellerin, 
March 19, 2020; Yborra, March 19, 2020; Owen, March 19, 2020; Brown et 
al., April 30, 2020; Price et al., May 1, 2020; ORCHSE, October 9, 
2020). These petitions and supporting letters argued that many 
employees had been infected because of workplace exposures to the virus 
that causes COVID-19, and that immediate, legally enforceable action is 
necessary for protection. OSHA quickly began issuing detailed guidance 
documents and alerts beginning in March 2020 that helped employers to 
determine employee risk levels of COVID-19 exposure and made 
recommendations for appropriate controls. As explained in detail in 
Section IV. of the Healthcare ETS, 86 FR 32376, 32412-13 (June 21, 
2021) and hereby included in the record for this ETS,\16\ at the time, 
OSHA leadership believed that implementing a combination of enforcement 
tools, including guidance, existing OSHA standards, and the General 
Duty Clause, would provide the necessary protection for workers. OSHA 
also expressed concern that an ETS might unintentionally enshrine 
requirements that are subsequently proven ineffective in reducing 
transmission.
---------------------------------------------------------------------------

    \16\ This adoption includes the citations in the referenced 
section of the Healthcare ETS, which are also included in the docket 
for this ETS.
---------------------------------------------------------------------------

    When it decided not to issue an ETS in the spring of 2020, OSHA 
determined that the agency could provide sufficient employee protection 
against COVID-19 through enforcing existing workplace standards and the 
General Duty Clause of the OSH Act, coupled with issuing industry-
specific, non-mandatory guidance. However, in doing so OSHA indicated 
that its conclusion that an ETS was not necessary was specific to that 
time, and that the agency would continue to monitor the situation and 
take additional steps as appropriate (see, e.g., OSHA, March 18, 2020 
Letter to Congressman Scott (stating ``[W]e currently see no additional 
benefit from an ETS in the current circumstances relating to COVID-19. 
OSHA is continuing to monitor this quickly evolving situation and will 
take the appropriate steps to protect workers from COVID-19 in 
coordination with the overall U.S. government response effort.'' 
(emphasis supplied); DOL May 29, 2020 at 20 (stating ``OSHA has 
determined this steep threshold [of necessity] is not met here, at 
least not at this time.'' (emphasis supplied))).
    In addition to the various petitions for rulemaking that were 
submitted to OSHA, the AFL-CIO filed a petition for a writ of mandamus 
with the U.S. Court of Appeals for the D.C. Circuit, requesting that 
the court compel OSHA to issue an ETS. (AFL-CIO, May 18, 2020). In its 
administrative decision and filing in that case, OSHA explained that 
the determination not to issue an ETS was based on the conditions and 
information available to the agency at that time and was subject to 
change as additional information indicated the need for an ETS. On June 
11, 2020, the U.S. Court of Appeals for the D.C. Circuit issued a one 
paragraph per curiam order denying the AFL-CIO's petition to require 
OSHA to issue an ETS. To be clear, nothing in OSHA's prior position or 
the D.C. Circuit's decision in In re Am. Fed'n of Labor & Cong. of 
Indus. Orgs., No. 20-1158, 2020 WL 3125324 (D.C. Cir. June 11, 2020); 
rehearing en banc denied (July 28, 2020) precludes OSHA's decision to 
promulgate an ETS now. To the contrary, at an early phase of the 
pandemic, when vaccines were not yet available and when it was not yet 
known how extensive the impact would be on illness and death, the court 
decided not to second-guess OSHA's decision to hold off on regulation 
in order to see if its nonregulatory enforcement tools could be used to 
provide adequate protection against the virus. ``OSHA's decision not to 
issue an ETS is entitled to considerable deference,'' the court 
explained, noting ``the unprecedented nature of the COVID-19 pandemic'' 
and concluding merely that ``OSHA reasonably determined that an ETS is 
not necessary at this time.'' (Id., with emphasis added).
    Employers do not have a reliance interest in OSHA's prior decision 
not to issue an ETS on May 29, 2020, which did not alter the status quo 
or require employers to change their behavior. See Dep't of Homeland 
Security v. Regents of the Univ. of California, 140 S. Ct. 1891, 1913-
14 (2020). As OSHA indicated when it made the decision, the 
determination was based on the conditions and information available to 
the agency at that time and was subject to change as additional 
information indicated the need for an ETS. In light of the agency's 
express qualifications and the surrounding context, any employer 
reliance would have been unjustified and cannot outweigh the 
countervailing urgent need to protect workers covered by this ETS from 
the grave danger posed by COVID-19.
b. OSHA's Decision To Promulgate a Healthcare ETS
    OSHA subsequently issued the Healthcare ETS to protect healthcare 
workers. 86 FR 32376. (June 21, 2021), codified at 29 CFR 1910.502. 
Looking back on a year of experience, OSHA found that its enforcement 
efforts had encountered significant obstacles, demonstrating that 
existing standards, regulations, and the General Duty Clause were 
inadequate to address the grave danger faced by healthcare employees. 
86 FR 32415. In promulgating that ETS, OSHA recognized that ``the 
impact of [COVID-19] has been borne disproportionately by the 
healthcare and healthcare support workers tasked with caring for those 
infected by this disease.'' 86 FR 32377. Furthermore, states and 
localities had taken increasingly divergent approaches to workplace 
protections against COVID-19, making it clear that a federal standard 
was needed to ensure sufficient protection in all states. 86 FR 32377. 
Therefore, OSHA focused on the unique situation experienced by 
healthcare industry workers as the frontline caregivers and support 
workers for those suffering from COVID-19. See 86 FR 32376, 32411-12.
    The Healthcare ETS requires employers to institute a suite of 
engineering controls, administrative controls, work practices, and 
personal protective equipment to combat the COVID-19 hazard. In the 
Preamble to the Healthcare ETS, OSHA observed that the development of 
safe and highly effective vaccines is a critical milestone in the 
nation's response to COVID-19, and that fully vaccinated persons have a 
greatly reduced risk of death, hospitalization and other health 
consequences. 86 FR 32396. The Healthcare ETS therefore includes 
provisions intended to encourage employees to become vaccinated, 
including a requirement for employers to provide reasonable paid leave 
for vaccination and recovery from any side effects. 86 FR 32415, 29 CFR 
1910.502(m).
    In the Healthcare ETS OSHA found that employees who work in covered 
healthcare workplaces are exposed to grave danger. 86 FR 32411. The 
agency also stated that in light of the effectiveness of vaccines, 
there was ``insufficient evidence in the record to support a grave 
danger finding for non-healthcare workplaces where all employees are 
vaccinated.'' 86 FR 32396 (emphasis supplied). OSHA made no finding at 
that time regarding unvaccinated workers in non-healthcare workplaces.


    No employer challenged the Healthcare ETS in court. The United Food 
and Commercial Workers Union (UFCW) together with the AFL-CIO filed a 
petition for review asserting that the rule should have gone further 
and included more industries in its scope (UFCW and AFL-CIO, June 24, 
2021). That case is being held in abeyance pending the issuance of this 
ETS.
c. Subsequent Developments
    The preamble to the Healthcare ETS notes that new COVID-19 variants 
might emerge that are more transmissible and cause more severe illness, 
but does not specifically mention the Delta Variant. See 86 FR 32384. 
Since publication of the Healthcare ETS, the Delta Variant has become 
the dominant form of the virus in the United States, causing large 
spikes in transmission, and surges of hospitalizations, and deaths, 
overwhelmingly among the unvaccinated (CDC, August 26, 2021; CDC, 
October 18, 2021--Variant Proportions, July Through October, 2021). As 
discussed in more detail in Grave Danger (Section III.A. of this 
preamble), the Delta Variant is at least twice as contagious as 
previous COVID-19 variants, and research suggests that it also causes 
more severe illness in the unvaccinated population (CDC, August 26, 
2021). More infections mean more potential for exposures, including in 
workplaces (see Grave Danger, Section III.A. of this preamble, for 
further discussion on workplace outbreaks, clusters, and the general 
impact of transmission in the workplace.). More infections also mean 
more opportunities for the virus to undergo mutations to its genetic 
code, resulting in genetic variants with the potential to infect or re-
infect people.
    Some variability in infection rates in a pandemic is to be 
expected. While the curves of new infections and deaths can bend down 
after peaks, they often reverse course only to reach additional peaks 
in the future (Moore et al., April 30, 2020). Last year experts 
expressed concern that one or more subsequent waves of COVID-19 were 
possible in 2021 (Moore et al., April 30, 2020), especially with new 
variants of COVID-19 in circulation (Doughton, February 9, 2021). That 
potential tragically became a reality with the spread of the Delta 
Variant.
    In June 2021, when the Healthcare ETS was published, COVID-19 
transmission rates in the United States were at a low point, with the 
7-day moving average of reported cases to be about 12,000. (CDC, August 
26, 2021) However, by the end of July, the 7-day moving average reached 
over 60,000 as the Delta Variant spread across the country. (CDC, 
August 26, 2021). The 7-day moving average of reported cases at the 
beginning of September, 2021 exceeded 161,000 (CDC, October 18, 2021--
Daily Cases). The most recent 7-day moving average of reported cases, 
while lower than the peak in late August and early September, is still 
over 85,000. (CDC, October 18, 2021--Daily Cases). These rates are also 
far higher than the rate when OSHA first declined to issue an ETS. 
(CDC, August 27, 2020 (20,401 confirmed cases per day on May 29, 
2020)). The jump in infections has resulted in increased 
hospitalizations and deaths for unvaccinated workers, as discussed in 
detail in Grave Danger (Section III.A. of this preamble). While the 
most current data reflect a decline in new cases from the peak, the 
level of new cases remains high. CDC data shows that, as of October 18, 
2021, approximately 85% of U.S. counties were experiencing ``high'' 
rates of community transmission, and another 10% were experiencing 
``substantial'' community transmission (CDC, October 18, 2021--Daily 
Cases). Although the number of new detected cases is currently 
declining nationwide (see CDC, October 18, 2021--Community Transmission 
Rates), the agency cannot assume based on past experience that 
nationwide case levels will not increase again. Indeed, many northern 
states are currently experiencing increases in their rate of new cases 
(see CDC, October 18, 2021--Cases, Deaths, and Laboratory Testing 
(NAATS) by State; Slotnik, October 18, 2021), including Vermont, which 
set a new record for new COVID-19 cases in mid-October 2021 (Murray, 
October 18, 2021). Unless vaccination rates increase, the experience of 
northern states during this fall could presage a greater resurgence in 
cases this winter as colder weather drives more individuals indoors 
(see Firozi and Dupree, October 18, 2021).
    While it is important to recognize that the Delta Variant has 
caused a spike in hospitalization and death in the United States, the 
SARS-CoV-2 virus, and not just a particular variant of that virus, is 
the hazard that workers face (see Grave Danger, Section III.A. of this 
preamble). Like any virus, SARS-CoV-2 has the ability to mutate over 
time and produce variants that may be more or less severe. Indeed, the 
World Health Organization and the CDC both track new variants that have 
continued to arise, such as the Lamda and Mu Variants (WHO, October 12, 
2021; CDC, October 4, 2021). At this time, the CDC is tracking 11 
different variants of COVID-19 (CDC, October 4, 2021). The World Health 
Organization has classified the Lambda and Mu variants as ``variants of 
interest,'' meaning that they have genetic changes that affect 
transmissibility, disease severity, immune escape, diagnostic or 
therapeutic escape; and have been identified to cause significant 
community transmission or multiple COVID-19 clusters, in multiple 
countries with increasing relative prevalence alongside increasing 
number of cases over time, or other apparent epidemiological impacts to 
suggest an emerging risk to global public health (WHO, October 12, 
2021). Medical experts have also explained that vaccination reduces the 
opportunities for the virus to continue to mutate by reducing 
transmission and length of infection. And, there is no indication that 
future variants of COVID-19 will not be equally or even more dangerous 
than Delta without a higher rate of vaccination (Bollinger and Ray, 
July 23, 2021).
    Meanwhile, evidence on the power of vaccines to safely protect 
individuals from infection and especially from serious disease has 
continued to accumulate. (CDC, May 21, 2021). For example, as explained 
in more detail in Grave Danger (Section III.A. of this preamble), 
multiple studies have demonstrated that vaccines are highly effective 
at reducing instances of hospitalization and death. In September the 
CDC compiled data from various studies that demonstrated overall 
authorized vaccines reduced death and severe case rates by 91 and 92% 
respectively in the population studied between April and July (Scobie 
et al., September 17, 2021, Table 1.). Additionally, the FDA granted 
approval to the Pfizer-BioNTech COVID-19 Vaccine for individuals 16 
years of age and older on August 23, 2021 (FDA, August 23, 2021). In 
announcing the decision, the FDA Commissioner explained that ``[w]hile 
this and other vaccines have met the FDA's rigorous, scientific 
standards for emergency use authorization, as the first FDA-approved 
COVID-19 vaccine, the public can be very confident that this vaccine 
meets the high standards for safety, effectiveness, and manufacturing 
quality the FDA requires of an approved product.'' (FDA, August 23, 
2021.)
    Despite this important milestone, and the demonstrated 
effectiveness of the approved and authorized vaccines available to the 
public, millions of employees remain unvaccinated, approximately 39% of 
workers who are covered by this ETS (See Economic Analysis, Section 
IV.B. of this ETS). The rate of vaccination in the United States


has slowed significantly from its peak in April, when the daily number 
of vaccination doses administered exceeded three million at one point. 
In recent months, daily vaccination rates have hovered around one 
million doses administered, or lower (CDC, October 18, 2021--Daily 
Vaccination Rate). The shortfall in vaccination leaves the nation's 
working population vulnerable to sickness, hospitalization and death, 
whether today under the Delta Variant, or under future variants that 
may arise (CDC, October 18, 2021--Daily Vaccination Rate); see also 
Grave Danger (Section III.A. of this preamble).
    Moreover, in recent months, an increasing number of states have 
promulgated Executive Orders or statutes that prohibit workplace 
vaccination policies that require vaccination or proof of vaccination 
status, thus attempting to prevent employers from implementing the most 
efficient and effective method for protecting workers from the hazard 
of COVID-19 (see, e.g., Texas Executive Order GA-40, October 11, 2021; 
Montana H.B. 702, July 1, 2021; Arkansas S.B. 739, October 4, 2021 and 
Arkansas H.B. 1977, October 1, 2021; AZ Executive Order 2021-18, August 
16, 2021). While some States' bans have focused on preventing local 
governments from requiring their public employees to be vaccinated or 
show proof of vaccination, the Texas, Montana, and Arkansas 
requirements apply to private employers as well. Other states have 
banned local ordinances that require employers to ensure that customers 
who enter their premises wear masks, thus endangering the employees who 
work there, particularly those who are unvaccinated (see, e.g., Florida 
Executive Order 21-102, May 3, 2021; Texas Executive Order GA-34, March 
2, 2021).
    In short, at the present time, workers are becoming sick and dying 
unnecessarily as a result of occupational exposures, when there is a 
simple and effective measure, vaccination, that can largely prevent 
those deaths and illnesses (see Grave Danger, Section III.A. of this 
preamble). Congress charged OSHA with responsibility for issuing 
emergency standards when they are necessary to protect employees from 
grave danger. 29 U.S.C. 655(c). In light of the current situation, OSHA 
is issuing this emergency rule.

II. This ETS Is Necessary To Protect Unvaccinated Employees From Grave 
Danger
    As explained at length in the preceding section (Grave Danger, 
Section III.A. of this preamble), OSHA has determined that most 
unvaccinated workers across the U.S. economy are facing a grave danger 
posed by the COVID-19 hazard.\17\ This new hazard has taken the lives 
of more than 725,000 people--many of them workers--in the United States 
since it was first detected in this country in early 2020. As the 
federal agency tasked with protecting the safety and health of workers 
in the United States, OSHA is required to act when it finds that 
workers are exposed to a grave danger. 29 U.S.C. 655(c)(1). OSHA now 
finds that this emergency temporary standard is necessary to protect 
employees who are unvaccinated. Asbestos Info. Ass'n, 727 F.2d at 423 
(``failure to act does not conclusively establish that a situation is 
not an emergency . . . [when there is a grave danger to workers,] to 
hold that because OSHA did not act previously it cannot do so now only 
compounds the consequences of the Agency's failure to act.''). As 
explained in detail below, OSHA has determined that vaccination is the 
most effective control for abating the grave danger that unvaccinated 
employees face from the COVID-19 hazard. And, for workers who are not 
vaccinated, the use of testing, face coverings, and removal from the 
workplace, while not as effective as vaccination, is still effective 
and necessary.
---------------------------------------------------------------------------

    \17\ As explained in the Grave Danger section, this ETS focuses 
on protecting unvaccinated workers from the grave danger that COVID-
19 poses in the workplace. OSHA did not include fully vaccinated 
workers in its finding of grave danger because such workers are 
generally much better protected from the effects of COVID-19, and, 
in particular, the most severe effects, than workers who are 
unvaccinated. OSHA's action in adopting this ETS for unvaccinated 
workers does not mean that vaccinated workers do not face a 
significant risk from COVID-19, or that the OSH Act's general duty 
clause poses no obligation on employers to protect their vaccinated 
workers from COVID-19. Indeed, symptomatic infections can occur in 
fully vaccinated people, and COVID-19 therefore poses at least some 
risk to vaccinated workers. OSHA has requested comment on the risks 
faced by vaccinated workers from COVID-19, and what additional 
measures, if any, should be taken to protect both vaccinated and 
unvaccinated workers (see Request for Comments, Section I.B. of this 
preamble).
---------------------------------------------------------------------------

    OSHA has determined that the best method for addressing the grave 
danger that COVID-19 poses to unvaccinated workers is to strongly 
encourage the use of the single most effective and efficient protection 
available: Vaccination. OSHA


has long recognized the importance of vaccinating workers against 
preventable illnesses to which they may be exposed on the job. See 56 
FR 64004, 64152 (Dec. 6, 1991) (discussing requirement in Bloodborne 
Pathogens standard for employer to make hepatitis B vaccine available 
to any employees with occupational exposure to blood and other 
potentially infectious materials). As explained in Grave Danger 
(Section III.A. of this preamble), COVID-19 vaccines do not completely 
eliminate the potential for infection, but significantly reduce the 
likelihood of infection, and in turn, transmission of the virus to 
others. Data from clinical trials for all three vaccines and 
observational studies for the two mRNA vaccines clearly establish that 
fully vaccinated persons have a greatly reduced risk of SARS-CoV-2 
infection compared to unvaccinated individuals (see FDA, December 11, 
2020; FDA, December 18, 2020; FDA, February 26, 2021).
    More importantly, vaccination is the single most effective method 
for protecting workers from the most serious consequences of a COVID-19 
infection: Hospitalization and death. Although symptomatic infections 
can occur in fully vaccinated people, they are less likely to occur, 
and are far less likely to result in severe health outcomes or death. 
As discussed in Grave Danger (Section III.A. of this preamble), studies 
have established that the available COVID-19 vaccines are highly 
effective at preventing hospitalization, and even more effective at 
preventing death. For example, one study found that unvaccinated adults 
age 18 to 49 were 15.2 times more likely to be hospitalized and 17.2 
times more likely to die of COVID-19 than fully vaccinated people in 
the same age range, and unvaccinated adults age 50 to 64 were 10.9 
times more likely to be hospitalized and 17.9 times more likely to die 
than their fully vaccinated peers (Scobie et al., September 17, 2021). 
The New York Times reported on October 1, 2021, that of the 
approximately 100,000 individuals who died of COVID-19 since mid-June 
2021, less than 3% had been identified by the CDC as vaccinated 
individuals (Boseman and Leatherby, October 1, 2021).
    Vaccines are also uniquely effective when compared to non-
pharmaceutical methods for controlling exposure to COVID-19 at the 
workplace. To be sure, non-pharmaceutical controls play an important 
role in employers' efforts to prevent exposure to the virus; as 
discussed in detail earlier, OSHA has, throughout the pandemic, advised 
employers to implement various administrative, engineering, and other 
controls to reduce workplace exposure to the virus. And, for certain 
work settings in the healthcare industry where people with COVID-19 are 
reasonably expected to be present, OSHA both encouraged vaccination and 
mandated a suite of protections, many of which involve physical 
controls (see 29 CFR 1910.502). Indeed, workers who work indoors and 
near others are best protected from COVID-19 when they are fully 
vaccinated and their exposure to COVID-19 is reduced (to the extent 
possible) by non-pharmaceutical controls.
    Non-pharmaceutical controls, however, focus on preventing employee 
exposure to the virus, and do not directly affect an employee's immune 
response if exposure to the virus does occur. Additionally, non-
pharmaceutical controls often rely on the actions of individuals and/or 
the integrity of equipment to be effective; for example, to use PPE to 
control exposure, a worker must correctly don appropriate PPE each time 
there is potential exposure, must properly clean, store, and maintain 
the PPE between uses, and must replace the PPE when it is no longer 
effective (see, e.g., 29 CFR 1910.132 (general PPE requirements in 
general industry workplaces)). Accordingly, OSHA standards have always 
followed the principle of the hierarchy of controls, under which 
employers must control hazards by means other than PPE whenever 
feasible, and PPE is a supplementary control. See e.g., 29 CFR 
1910.134(a); 29 CFR 1910.1030(d)(2).
    Physical distancing requires workers to maintain constant awareness 
of their environment in order to avoid coming into close proximity with 
colleagues, customers, or other individuals, even though the realities 
of their jobs and/or the design of the workplace may be unaccommodating 
to that effort. Requiring employees to examine themselves for signs and 
symptoms consistent with SARS-CoV-2 infection before reporting to work 
is prone to human error and entirely ineffective when the employee is 
infected but asymptomatic or pre-symptomatic.
    In contrast, a worker is considered fully vaccinated after 
completing primary vaccination with a COVID-19 vaccine, or the second 
dose of any combination of two doses of a COVID-19 vaccine that is 
approved, authorized, or listed as a two-dose primary vaccination by 
the FDA or WHO (see the Summary and Explanation for paragraph (c), 
Section VI.C. of this preamble). Once fully vaccinated, a worker enjoys 
automatic and long-lasting benefits; namely, a drastic reduction in the 
risk of severe health effects or death. The vaccine works by bolstering 
the worker's immune system and does not depend on the worker's acumen 
or actions to afford its protection. Moreover, where an employer 
implements one or more non-pharmaceutical controls at the workplace, 
vaccination provides workers with a backstop of protection that greatly 
reduces their risk of serious health effects if they are exposed to the 
virus despite the presence of other controls. Vaccination thus ensures 
that workers need not rely on other factors, be it the workplace 
environment, the effectiveness of equipment, or the actions of other 
individuals, to be substantially protected from the worst potential 
outcomes of a COVID-19 infection.
    This ETS focuses on encouraging vaccination because it is the most 
efficient and effective method for addressing the grave danger. 
Vaccination is patently appropriate and feasible for almost every 
worker in all industries, and will drastically reduce the risk that 
unvaccinated workers will suffer the serious health outcomes associated 
with SARS-CoV-2 infection. As described in Section III.A. of this 
preamble (Grave Danger), employees who are unvaccinated are in grave 
danger from the SARS-CoV-2 virus, but employees who are fully 
vaccinated are not. Since it is the lack of vaccination that results in 
grave danger, vaccination will best allay the grave danger. This ETS, 
which is designed to strongly encourage vaccination, is thus 
``necessary to protect employees'' from a grave danger. 29 U.S.C. 
655(c).
    OSHA continues to encourage employers to implement additional 
controls that may be appropriate to eliminate exposure to the SARS-CoV-
2 virus at their workplace, but, as discussed further below, OSHA has 
not required employers to implement a comprehensive and multilayered 
set of COVID-19 exposure controls in this ETS. This decision reflects 
the extraordinary and exigent circumstances have required OSHA to 
immediately promulgate this emergency temporary standard. Although OSHA 
was able to design a comprehensive infection prevention program for the 
specific healthcare settings to which the June 2021 Healthcare ETS 
applied, this rule encompasses all industries covered by the OSH Act, 
and targets unvaccinated workers in any indoor work setting not covered 
by the Healthcare ETS where more than one person is present. Crafting a 
multi-layered standard that is comprehensive and feasible for all


covered work settings, including mixed settings of vaccinated and 
unvaccinated workers, is an extraordinarily challenging and complicated 
undertaking, yet the grave danger that COVID-19 poses to unvaccinated 
workers obliges the agency to act as quickly possible. As discussed 
above, OSHA has identified vaccination as the single most efficient and 
effective means for removing an unvaccinated worker from the grave 
danger.
    Given the urgency of the rulemaking, and the singular effectiveness 
of vaccination in removing unvaccinated workers from the grave danger, 
OSHA is promulgating this ETS to immediately address the grave danger 
that COVID-19 poses to unvaccinated workers by strongly encouraging 
vaccination. As discussed in Pertinent Legal Authority (Section II. of 
this preamble), a ``grave danger'' represents a risk greater than the 
``significant risk'' that OSHA must show in order to promulgate a 
permanent standard under section 6(b) of the OSH Act, 29 U.S.C. 655(b). 
OSHA will consider whether it is necessary to require additional 
controls to avert a significant risk of harm in the rulemaking 
proceedings that follow this ETS. OSHA directs employers to its 
website, www.osha.gov/coronavirus, and the CDC's website, www.cdc.gov/coronavirus, for guidance on the engineering, administrative, and other 
exposure controls that may be effective and appropriate for their 
workplace.
    OSHA expects that, by strongly encouraging vaccination, this ETS 
will have a positive impact on worker health. As discussed above, 
millions of workers remain unvaccinated and are presently exposed to 
risks of hospitalization and death many times higher than their 
vaccinated coworkers. Although predicting the health impact of this ETS 
is particularly challenging, given the ever-changing nature of the 
pandemic and the many factors that may motivate workers to become fully 
vaccinated, OSHA has attempted to quantify the potential number of 
hospitalizations and fatalities that this ETS could avert by increasing 
workforce vaccination rates (see OSHA, October 2021c). OSHA has 
estimated that, as a result of the ETS, over 6,500 fewer currently 
unvaccinated workers will die from COVID-19 over the next six months. 
OSHA also estimates that this ETS will prevent over 250,000 currently 
unvaccinated workers from being hospitalized during that same time 
period. Even if OSHA's estimate does not prove to be precisely 
accurate, OSHA is confident that this ETS will save hundreds of lives 
and prevent thousands of workers from becoming severely ill.
a. OSHA Finds It Necessary To Strongly Encourage Vaccination
    Despite the proven safety and efficacy of the available COVID-19 
vaccines, many workers remain unvaccinated and are currently exposed to 
a grave danger. As discussed in Grave Danger (Section III.A. of this 
preamble), countless COVID-19 outbreaks have occurred in myriad work 
settings where employees come into contact with others, and in recent 
weeks, the majority of states in the U.S. have experienced what CDC 
defines as high or substantial community transmission, indicating that 
there is a clear risk of the virus being introduced into and 
circulating in workplaces (CDC, October 18, 2021--Community 
Transmission Rates). As of October 18, 2021, more than 184 million 
people in the United States have been fully vaccinated, but only 68.5% 
of people ages 18 years or older are fully vaccinated (CDC, October 18, 
2021--Fully Vaccinated). OSHA has estimated that approximately 62.4% 
percent of adults aged 18-74 within the scope of this ETS are either 
fully vaccinated or received their first vaccine dose during the 
previous two weeks, leaving approximately 31.7 million unvaccinated 
(i.e., not fully vaccinated and did not receive a first dose with in 
the past two weeks) (see Economic Analysis, Section IV.B. of this 
preamble, Table IV.B.7). Meanwhile, the rate of new vaccinations has 
slowed considerably; on October 15, 2021, the 7-day moving average 
number of administered vaccine doses reported to the CDC per day was 
841,731 doses, a steep reduction from the peak 3,448,156 dose average 
that the CDC reported on April 11, 2021 (CDC, October 18, 2021--Weekly 
Review).
    Given the pervasiveness of the virus in workplaces across the 
country and the unparalleled efficacy of vaccines at preventing serious 
health effects, OSHA finds it necessary to strongly encourage 
vaccination. Encouraging vaccination is principally necessary to reduce 
the likelihood that workers who are infected by the SARS-CoV-2 virus 
will suffer the worst outcomes of an infection (hospitalization and 
death). Put simply, the single best method for protecting an 
unvaccinated worker from the serious health consequences of a COVID-19 
infection is for that worker to become fully vaccinated.
    Additionally, encouraging vaccination is necessary to reduce the 
overall prevalence of the SARS-CoV-2 virus at workplaces. Because 
vaccinated workers are less likely than unvaccinated workers to be 
infected by the virus, they are less likely to spread the virus to 
others at their workplace, including to unvaccinated coworkers. 
Increasing workforce vaccination rates will therefore reduce the risk 
that unvaccinated workers will be infected by a coworker.
    Evidence shows that mandating vaccination has proven to be an 
effective method for increasing vaccination rates, and that vaccination 
mandates have generally been more effective than merely encouraging 
vaccination. Significant numbers of workers would get vaccinated if 
their employers required it, and many workers who were vaccinated over 
the last four months were motivated by their employer requiring 
vaccination. The Kaiser Family Foundation (KFF) vaccine monitor, an 
ongoing research project tracking the public's attitudes and 
experiences with COVID-19 vaccinations, conducted a survey from 
September 13 to September 22, 2021, among a nationally representative 
random digit dial telephone sample of 1,519 adults ages 18 and older, 
and found that those who received their first dose of a COVID-19 
vaccine after June 1, 2021 were motivated by mandates of various sorts, 
including one in five (19%) who say a major reason was that their 
employer required it (KFF, September 2021). A survey conducted by 
Change Research from August 30 to September 2, 2021 regarding 
Americans' views on COVID-19 vaccines found that among the 1,775 
respondents, ``one of the things that was most likely to lead someone 
to get vaccinated was if their employer required it'' (Towey, September 
27, 2021).
    Vaccine mandates imposed by state governments and large employers 
have also demonstrated the effectiveness of mandates in increasing 
vaccination rates. For example, when Tyson Foods announced its 
vaccination requirement in early August 2021, only 45% of its workforce 
had received a vaccination dose, but as of September 30, 2021, the New 
York Times reported that has increased to 91% (White House, October 7, 
2021; Hirsch, September 30, 2021). Similarly, United Airlines reported 
that 97% of its U.S.-based employees were fully vaccinated against 
COVID-19 within a week of the deadline of the company's vaccination 
mandate, and the 3% who were not fully vaccinated included several 
employees who sought a medical or religious exemption from vaccination 
(The Associated Press, September 22, 2021). In Washington State, the 
weekly vaccination rate increased 34% after the Governor announced 
vaccine requirements for


state workers (White House, October 7, 2021). The success of these 
COVID-19 vaccination mandates comports with the National Safety 
Council's recent finding that employers that instituted a COVID-19 
vaccination mandate produced a 35% increase in employee vaccination 
(NSC, September 2021). Similarly, the White House recently reported 
that its analysis of vaccination requirements imposed by healthcare 
systems, educational institutions, public-sector agencies, and private 
businesses demonstrated that such requirements increased their 
vaccination rates by more than 20 percentage points and have routinely 
seen their share of fully vaccinated workers rise above 90 percent 
(White House, October 7, 2021).
    Given the effectiveness of vaccination mandates in increasing 
vaccination rates, OSHA expects that, in most instances, an employer 
implementing a policy that requires all employees to be vaccinated will 
be the most effective approach for increasing the vaccination rate of 
its employees and ensuring that they have the best protection available 
against the worst consequences of a COVID-19 infection. Although OSHA 
may well have the authority to impose a vaccination mandate, OSHA has 
decided against pursuing strict vaccination requirement and has instead 
crafted the ETS to strongly encourage vaccination. Employers are in the 
best position to understand their workforces and the approach that will 
work most effectively with them to secure employee cooperation and 
protection. OSHA's traditional practice when including medical 
procedures, such as medical surveillance testing and vaccinations, in 
its health standards has been to require the employer to make the 
medical procedure available to employees, and has viewed mandating 
those procedures as a measure to avoid if possible. For example, when 
the agency promulgated its standard regulating occupational exposure to 
lead, OSHA considered mandating that employees participate in physical 
examinations and biological monitoring, but ultimately required 
employers to make them available to employees (see 43 FR 54354, 54450 
(Nov. 21, 1978)). OSHA decided against mandating those procedures in 
part because it believed a voluntary approach would elicit more 
effective employee participation in the medical program and in part 
because of the agency's concerns about the Government intruding into a 
private and sensitive area of workers' lives (43 FR at 54450-51). OSHA 
has followed that same approach of requiring employers to ``provide'' 
or ``make available'' medical procedures to employees in numerous 
subsequent standards, such as the standards for asbestos (29 CFR 
1910.1001), benzene (1910.1028), cotton dust (1910.1043), and 
formaldehyde (1910.1048).
    OSHA adhered to this approach when it promulgated the Bloodborne 
Pathogens standard. The agency considered mandating a Hepatitis B 
vaccination, but instead required employers to make the Hepatitis B 
vaccination available to employees. 56 FR 64004, 64155 (Dec. 6, 1991); 
29 CFR 1910.1030(f)(1)(i), (f)(2)(i). OSHA explained that the agency 
may have the legal authority to mandate vaccination, but believed that, 
under the circumstances, a voluntary vaccination program would ``foster 
greater employee cooperation and trust in the system'' and ``enhance [ 
] compliance while respecting individuals' beliefs and rights to 
privacy.'' 56 FR at 64155.
    In keeping with this traditional practice, the agency has stopped 
short of including a strict vaccination mandate with no alternative 
compliance option in this ETS. OSHA has never done so, and if it were 
to take that step, OSHA believes it more prudent to do so where the 
agency has ample time to fully assess the potential ramifications of 
imposing a vaccination mandate on covered employers and employees. 
Here, exigent circumstances demand that OSHA take immediate action to 
protect workers from the grave danger posed by COVID-19, but OSHA has 
not had a full opportunity to study the potential spectrum of impacts 
on employers and employees, including the economic and health impacts, 
that would occur if OSHA imposed a strict vaccination mandate with no 
alternative compliance option. Moreover, employers in their unique 
workplace settings may be best situated to understand their workforce 
and the strategies that will maximize worker protection while 
minimizing workplace disruptions. These considerations persuade the 
agency that this ETS should afford employers some flexibility in the 
form of an alternative option to strictly mandating vaccination. In 
light of the unique and grave danger posed by COVID-19, OSHA has 
requested comment on whether a strict vaccination mandate is warranted 
and the agency will consider all the information it receives as it 
determines how to proceed with this rulemaking (see Request for 
Comment, Section I.B. of this preamble).
    Although this ETS does not impose a strict vaccination mandate, 
OSHA has determined that, to adequately address the grave danger that 
COVID-19 poses to unvaccinated workers, a more proactive approach is 
necessary than simply requiring employers to make vaccination available 
to employees. None of the standards that OSHA promulgated prior to this 
year concerned an infectious agent as readily transmissible as COVID-
19. Standards like the Lead standard do not concern infectious agents 
that can be transmitted between individuals at a workplace; 
accordingly, the medical procedures that employers are required to make 
available under those standards are solely aimed at protecting the 
health of the worker who is undergoing the procedure. The Bloodborne 
Pathogens standard concerned exposure to infectious biological agents 
(Hepatitis B and HIV) that can be transmitted between individuals, but 
the potential for those agents to be transmitted between workers is 
minimal in comparison to the SARS-CoV-2 virus; Hepatitis B and HIV are 
transmitted through blood and certain body fluids, whereas the SARS-
CoV-2 virus spreads through respiratory droplets that can travel 
through the air from worker-to-worker (see Grave Danger, Section III.A. 
of this preamble). Vaccination against COVID-19 is thus particularly 
important in reducing the potential for workers to become infected and 
spread the virus to others at the workplace, in addition to protecting 
the worker from severe health outcomes if they are infected. Moreover, 
the ease with which the SARS-CoV-2 virus spreads between workers makes 
it more urgent for workers to be vaccinated, and this urgency 
contributes to the agency's decision to strongly encourage vaccination.
    Accordingly, to further the goal of increasing workforce 
vaccination rates, this ETS requires employers to implement a mandatory 
vaccination policy unless they adopt a policy in which employees may 
either be fully vaccinated or regularly tested for COVID-19 and wear a 
face covering in most situations when they work near other individuals. 
Employers have the duty under the OSH Act to provide safe workplaces to 
their employees, including protecting employees from known hazards by 
complying with occupational safety and health standards (see 29 U.S.C. 
654), and this ETS therefore provides employers with two compliance 
options for protecting unvaccinated workers from the grave danger posed 
by COVID-19. But while this ETS offers employers a choice in how to 
comply, OSHA has presented implementation of a vaccination mandate as 
the preferred compliance


option; as discussed above, vaccine mandates have proven to be 
effective in increasing vaccination rates, and OSHA expects that, in 
most instances, implementing a vaccination mandate will be the most 
effective method for increasing a workforce's vaccination rate. As 
discussed below, OSHA also recognizes that requiring that all employees 
be vaccinated provides more protection to vaccinated workers than 
regularly testing unvaccinated workers for COVID-19 and requiring them 
to wear face coverings when they work near others. This ETS will 
preempt inconsistent state and local requirements, including 
requirements that ban or limit employers' authority to require 
vaccination (see the Summary and Explanation for paragraph (a), Section 
VI.A. of this preamble), and will therefore provide the necessary legal 
authorization to covered employers to implement mandatory vaccination 
policies, if they choose to comply in this preferred manner.
    Although the ETS does not require all covered employers to 
implement a mandatory vaccination policy, OSHA expects that employers 
that choose that compliance option will enjoy advantages that employers 
that opt out of the vaccination mandate option will not. Most 
obviously, employers with a mandatory vaccination policy will enjoy a 
dramatically reduced risk that their employees will become severely ill 
or die of a COVID-19 infection. In addition, employers who implement a 
vaccination mandate will likely have fewer workers temporarily removed 
from the workplace due to a COVID-19 positive test; this rule requires 
all covered employers to remove from the workplace any employee who 
tests positive for COVID-19 or receives a diagnosis of COVID-19 (see 
the Summary and Explanation for paragraph (h), Section VI.H. of this 
preamble), and because vaccinated workers are less likely than 
unvaccinated workers to be infected by the virus, OSHA expects 
employers with a mandatory vaccination policy will be statistically 
less likely to be obliged to remove a COVID-positive employee from the 
workplace in accordance with paragraph (h)(2). Additionally, only 
employers who decline to implement a mandatory vaccination program are 
required by the rule to assume the administrative burden necessary to 
ensure that unvaccinated workers are regularly tested for COVID-19 and 
wear face coverings when they work near others.
    Where employers opt out of implementing a mandatory vaccination 
program, the ETS encourages employees to elect to be fully vaccinated. 
As discussed in the Summary and Explanation for paragraph (f) (Section 
VI.F. of this preamble), the ETS requires all covered employers to 
support vaccination by providing employees with reasonable time, 
including up to four hours of paid time, to receive each vaccination 
dose, and reasonable time and paid sick leave to recover from 
vaccination side effects. Many workers have been deterred from 
receiving vaccination by fears of missing work and/or losing pay to 
obtain vaccination and/or recover from side effects (see Section VI.F. 
of this preamble; see, e.g., KFF, May 6, 2021; KFF, May 17, 2021), and 
OSHA finds that this employer support is necessary to ensure that 
employees can become fully vaccinated without concern that they will be 
sacrificing pay or their jobs to do so.
    All covered employers are required by the ETS to bear the cost of 
providing up to four hours of paid time and reasonable paid sick leave 
needed to support vaccination, but where an employee chooses to remain 
unvaccinated, the ETS does not require employers to pay for the costs 
associated with regular COVID-19 testing or the use of face coverings 
(see the Summary and Explanation for paragraphs (g) and (i), Sections 
VI.G. and VI.I. of this preamble). In some cases, employers may be 
required to pay testing and/or face covering costs under other federal 
or state laws or collective bargaining obligations, and some may choose 
to do so even without such a mandate, but otherwise employees will be 
required to bear the costs if they choose to be regularly tested and 
wear a face covering in lieu of vaccination.
    This ETS more strongly encourages vaccination than the June 2021 
Healthcare ETS. OSHA designed the Healthcare ETS, which addresses the 
grave danger that COVID-19 poses workers in specific health care 
settings where COVID-19-positive individuals are reasonably likely to 
be present, to encourage vaccination (see 86 FR at 32415, 32423, 32565, 
32597). Specifically, the Healthcare ETS encourages vaccination by 
requiring employers to provide employees reasonable and paid time to 
receive vaccination doses and recover from side effects (29 CFR 
1910.502(m)), and by exempting from its scope ``well-defined hospital 
ambulatory care settings where all employees are fully vaccinated'' and 
all non-employees are screened and denied entry if they are suspected 
or confirmed to have COVID-19 (1910.502(a)(2)(iv)) and ``home 
healthcare settings where all employees are fully vaccinated'' and all 
nonemployees at that location are screened prior to employee entry so 
that people with suspected or confirmed COVID-19 are not present 
(1910.502 (a)(2)(v)).
    Similar to the Healthcare ETS, this ETS requires employers to 
support vaccination by providing employees with reasonable time, 
including up to four hours of paid time, to receive vaccination, and 
reasonable time and paid sick leave to recover from vaccination side 
effects (see discussion above and the Summary and Explanation for 
paragraph (f), Section VI.F. of this preamble). However, as discussed 
above, this ETS goes further and expressly requires the implementation 
of a mandatory vaccination policy, unless the employer implements an 
alternative policy that requires unvaccinated workers to be regularly 
tested for COVID-19 and to wear face coverings in most situations when 
they work near others. While nothing in the Healthcare ETS prohibits 
covered employers from implementing a mandatory vaccination policy, 
this ETS presents the implementation of a mandatory vaccination policy 
as a preferred compliance option, and will preempt inconsistent state 
and local requirements that ban or limit employers' authority to 
require vaccination. Additionally, where the employer opts out of 
implementing a mandatory vaccination policy, and the employee opts out 
of vaccination, this ETS places no obligation on the employer to pay 
for costs associated with the regular testing of unvaccinated workers 
for COVID-19 or their use of face coverings, which will provide a 
financial incentive for some employees to be fully vaccinated.
    OSHA finds it necessary to more strongly encourage vaccination in 
this ETS than in the Healthcare ETS in the manner described above. The 
Healthcare ETS's provisions that encouraged vaccination were packaged 
with a comprehensive infection prevention program that was tailored to 
the specific healthcare work settings to which the ETS applied, 
including a suite of layered and overlapping controls. In contrast, 
OSHA is promulgating this ETS to address the grave danger that COVID-19 
now poses to all unvaccinated workers who work indoors and in the 
presence of others. As mentioned above, crafting a comprehensive and 
multi-layered standard that is comprehensive and feasible for the 
myriad work settings to which this ETS will apply, including workplaces 
as diverse as schools, restaurants, retail settings, offices, prisons, 
and factories, is an


extraordinarily challenging and complicated undertaking.
    Exigent circumstances require OSHA to immediately promulgate this 
ETS to protect unvaccinated workers, and vaccination is the single most 
efficient and effective method for removing unvaccinated workers from 
the grave danger. Given the urgency of the rulemaking and the singular 
efficacy of vaccination, OSHA has decided against including 
comprehensive and multilayered exposure controls in this ETS, and is 
instead focusing the ETS on strongly encouraging vaccination. Strongly 
encouraging vaccination is thus critical to the effectiveness of this 
ETS at protecting unvaccinated workers from the grave danger. In 
Request for Comment (Section I.B. of this preamble), OSHA seeks 
information on what additional measures, if any, should be required to 
protect employees against COVID-19.
    Moreover, stronger encouragement of vaccination is needed in this 
ETS than in the Healthcare ETS because workers who are protected by the 
Healthcare ETS are more likely to be vaccinated and/or subject to a 
vaccination mandate. The Healthcare ETS, 29 CFR 1910.502, focused on 
healthcare work settings where COVID-19 is reasonably expected to be 
present, and, this ETS does not apply in settings where any employee 
provides healthcare services or healthcare support services while they 
are covered by the requirements of 29 CFR 1910.502 (see the Summary and 
Explanation for paragraph (b), Section VI.B. of this preamble). 
Evidence shows that workers in settings covered by Sec.  1910.502 
already have a high rate of vaccination. As of July 2021, healthcare 
workers had a higher rate of vaccination than non-healthcare workers 
(Lazer et al., August, 2021), and many healthcare workers are currently 
subject to vaccination mandates. Twenty-two states and the District of 
Columbia have instituted vaccination mandates that are applicable to 
healthcare workers (NASHP, October 1, 2021), and nearly 300 hospitals 
and broader health systems have implemented vaccine mandates for their 
employees (Renton et al., October 14, 2021). The White House reported 
that almost 2,500 hospitals, 40% of all U.S. hospitals, across all 50 
states, the District of Columbia, and Puerto Rico, have announced 
vaccination requirements for their workforce, and noted numerous 
examples of highly successful mandates in those workplaces (White 
House, October 7, 2021). News reports attest that many of these 
vaccination mandates have had great success in increasing the 
vaccination rate of the targeted healthcare workers (Goldberg, July 9, 
2021; Otterman and Goldstein, September 28, 2021; Hubler, September 30, 
2021; Beer, October 4, 2021). Even more healthcare workers covered by 
29 CFR 1910.502 will be subject to a vaccination mandate under the 
Centers for Medicare & Medicaid Services (CMS) rule published elsewhere 
in this issue of the Federal Register that requires COVID-19 
vaccinations for workers in most healthcare settings that receive 
Medicare or Medicaid reimbursement, including but not limited to 
hospitals, dialysis facilities, ambulatory surgical settings, and home 
health agencies. This CMS rule applies to at least 76,000 providers 
(i.e., employers) and covers a majority of healthcare workers across 
the country. OSHA expects that the combination of incentives to 
vaccination in the Healthcare ETS and vaccination mandates applicable 
to healthcare workers will leave few healthcare workers within the 
scope of the Healthcare ETS unvaccinated.
b. Unvaccinated Workers Must Be Regularly Tested for COVID-19 and Use 
Face Coverings
    As discussed above, this ETS presumptively requires employers to 
implement a mandatory vaccination policy, but permits employers to opt 
out of that requirement. Nonetheless, the grave danger that COVID-19 
poses to unvaccinated workers demands that alternative protective 
measures be taken at workplaces where the employer does not implement a 
mandatory vaccination policy. Given that the SARS-CoV-2 virus is highly 
contagious, transmitted easily through the air, and can lead to severe 
and/or fatal outcomes in unvaccinated workers, it is critical that 
employers who do not require their employees to be vaccinated implement 
controls to mitigate the potential for COVID-19 outbreaks to occur. As 
discussed above, and in Grave Danger (Section III.A. of this preamble), 
unvaccinated workers are more likely than vaccinated workers to be 
infected with COVID-19 and transmit the virus to others, and thus pose 
a heightened risk of spreading the virus at the workplace, including to 
other unvaccinated workers.
    To reduce the risk that unvaccinated workers will spread COVID-19 
at the workplace, this rule requires employers that do not implement a 
mandatory vaccination policy to ensure that unvaccinated workers who 
report to a workplace where others are present are tested at least once 
a week for COVID-19. As discussed in the Summary and Explanation for 
paragraph (g) (Section VI.G. of this preamble), it is well-established 
that, by identifying and isolating infected individuals, regularly 
testing individuals for COVID-19 infection can be an effective method 
for reducing virus transmission. Regularly testing unvaccinated workers 
is essential because SARS-CoV-2 infection is often attributable to 
asymptomatic or presymptomatic transmission (Bender et al., February 
18, 2021; Byambasuren et al., December 11, 2020; Johansson et al., 
January 7, 2021; Klompas et al., September 2021). In accordance with 
the CDC's recommendations, OSHA has set the minimum frequency of 
testing at 7 days because the agency expects that it will be effective 
in slowing the spread of COVID-19, while taking into account associated 
cost considerations (see the Summary and Explanation for paragraph (g), 
Section VI.G. of this preamble). As noted in the Request for Comment 
(Section I.B. of this preamble), OSHA is gathering additional 
information about whether OSHA should require testing more often than 
on a weekly basis.
    The requirement for unvaccinated workers to be regularly tested for 
COVID-19 operates in tandem with paragraph (h)(2), which requires that 
all employers remove from the workplace any employee who receives a 
positive COVID-19 test, or a COVID-19 diagnosis (see the Summary and 
Explanation for paragraph (h), Section VI.H. of this preamble). 
Paragraph (h)(2) ensures that the COVID-19-positive employee will be 
isolated from the workplace until it is safe for the employee to 
return, and also allows the employee to seek medical care sooner and 
reduce the likelihood that they will suffer the most severe 
consequences of an infection (e.g., by seeking monoclonal antibody 
treatment). The combination of the testing and medical removal 
provisions will reduce the likelihood that an unvaccinated worker who 
has been infected with COVID-19, including those who are not 
experiencing symptoms of infection, will be permitted to spread the 
virus to others at the workplace, including unvaccinated coworkers.
    Additionally, OSHA finds it necessary to require employers that do 
not implement a mandatory vaccination policy to ensure that 
unvaccinated workers wear face coverings in most situations when they 
are working near others. This reflects OSHA's recognition that 
regularly testing unvaccinated workers for COVID-19 will not be 100% 
effective in identifying infected workers before they enter the 
workplace. Most obviously, testing employees once a week will not 
prevent an unvaccinated


worker from exposing others at the workplace if the worker becomes 
infected and reports to the workplace in between their weekly tests. 
And, even if the rule required unvaccinated workers to be tested more 
frequently than once a week, infected persons may still be missed, 
particularly in areas with high community spread (Chin et al., 
September 9, 2020).
    Accordingly, requiring unvaccinated workers to wear face coverings 
in most situations when they are working near others will further 
mitigate the potential for unvaccinated workers to spread the virus at 
the workplace. As discussed in the Summary and Explanation for 
paragraph (i) (Section VI.I. of this preamble), it is well-established 
that face coverings provide effective source control; that is, they 
largely prevent respiratory droplets emitted by the wearer of the face 
covering from spreading to others, and thus make it significantly less 
likely that the person wearing the mask will transmit the virus, if 
they are infected. Face coverings are also believed to provide the 
wearer some limited protection from exposure to the respiratory 
droplets of co-workers and others (e.g., customers) (CDC, May 7, 2021), 
but the principal benefit of face coverings is to significantly reduce 
the wearer's ability to spread the virus. By requiring unvaccinated 
workers to wear face coverings, this rule significantly reduces the 
likelihood that an infected unvaccinated worker who enters the 
workplace despite the testing requirements will spread the virus to 
others, including unvaccinated coworkers.
    OSHA acknowledges that regularly testing unvaccinated workers for 
COVID-19 and requiring them to wear face coverings when they work near 
others is less protective of unvaccinated workers than simply requiring 
all workers to be vaccinated. To be sure, OSHA strongly prefers that 
employers adopt a mandatory vaccination policy, as vaccination is 
singularly effective at protecting workers from the severe consequences 
that can result from a COVID-19 infection. And, where employers do not 
adopt a mandatory vaccination policy, employers may also consider 
alternative feasible measures that would remove employees who remain 
unvaccinated from the scope of this ETS, such as increasing telework 
(see the Summary and Explanation for paragraph (b), Section VI.B. of 
this preamble). Nonetheless, as discussed above, OSHA has not imposed a 
strict vaccination mandate on all covered employees who work in the 
presence of others and not exclusively outdoors, given that the agency 
has never previously used its authority to strictly mandate 
vaccination, and the exigent and extraordinary circumstances driving 
this emergency rulemaking have not afforded OSHA a full opportunity to 
assess the potential ramifications of including a strict vaccination 
mandate in this rule. Given these circumstances, and employers' unique 
understanding of the compliance approaches that will best increase 
vaccination rates among their workforce, OSHA has designed a rule that 
preserves a limited degree of employer flexibility, and strongly 
encourages, but does not strictly require, vaccination. OSHA has 
requested comment in this ETS on whether a strict vaccination mandate 
would be appropriate and the agency will consider those comments as it 
determines how to proceed with this rulemaking.

III. No Other Agency Action is Adequate To Protect Employees Against 
Grave Danger
    OSHA's experience to date shows that the agency's existing tools 
are inadequate to meet the grave danger posed by COVID-19 to 
unvaccinated workers not covered by the Healthcare ETS. OSHA has 
determined that its existing standards, regulations, the OSH Act's 
General Duty Clause, and non-mandatory guidance will not adequately 
promote the most effective means to protect these workers: Vaccination. 
The agency has determined that this ETS is necessary to address these 
inadequacies. Multiple developments support this change in approach. 
First, large numbers of employees are continuing to contract COVID-19 
and die. (See Grave Danger, Section III.A. of this preamble). Further, 
based on a thorough review of its existing approach to protecting 
employees from COVID-19 and the current state of the pandemic, OSHA 
finds that existing OSHA standards, regulations, the General Duty 
Clause, and non-mandatory guidance are not adequate to protect 
employees outside healthcare from COVID-19. The Preamble to the 
Healthcare ETS includes a detailed analysis demonstrating the 
inadequacy of existing tools in the healthcare industry. See 86 FR 
32414-32423. In general, the same analysis applies here. The reasons 
existing tools were inadequate to protect healthcare workers apply in 
other industry sectors as well. The Healthcare ETS itself, while 
necessary to protect healthcare workers, of course applies only to that 
industry. Finally, the numerous guidance products published by other 
entities, such as CDC, are not adequate to protect employees because 
they are not enforceable; there is no penalty for noncompliance. 86 FR 
at 32415. Even as the CDC has increasingly recommended vaccination to 
protect from the dangers of transmission and severe illness related to 
the SARS-CoV-2 virus, vaccination rates remain uneven around the 
country. (CDC, September 9, 2021; Leonhardt, September 7, 2021; KFF, 
October 6, 2021; McPhillips and Cohen, May 19, 2021).
    The need for this ETS is also reflected in the number of states and 
localities that have issued their own mandatory standards in 
recognition that OSHA's existing measures (including non-mandatory 
guidance, compliance assistance, and enforcement of existing standards) 
have failed to prevent the spread of the virus in workplaces. 
Additionally, as mentioned previously, other states have banned certain 
employers from implementing workplace vaccination mandates or from 
verifying an employee's vaccination status or from requiring face 
coverings. A national standard is necessary to establish clear 
requirements regarding vaccination, testing and face coverings that 
will protect employees in all states and preempt state or local 
ordinances that prevent employers from implementing necessary 
protections.
a. The Current Standards and Regulations Are Inadequate
    In the Healthcare ETS, OSHA considered its enforcement efforts with 
regard to existing standards and regulations that OSHA had identified 
as potentially applicable to occupational exposure to SARS-CoV-2. 
OSHA's analysis in Section IV of the Healthcare ETS, 86 FR 32376, 
32416-17 and hereby included in the record of this ETS,\18\ is 
applicable here in considering the need for this ETS, which covers a 
much broader set of employers in all industries. There OSHA found that 
none of the existing OSHA standards could sufficiently abate the hazard 
posed by COVID-19 in healthcare settings. Here again OSHA concludes 
that the potentially applicable existing standards are insufficient to 
address the grave danger faced by workers covered by this ETS. None of 
the current standards, even if more rigorously enforced, can 
sufficiently address this cross-industry hazard of national proportions 
to abate the grave danger posed by COVID-19 or lead to the same 
benefits that this ETS will achieve. See Asbestos Info. Ass'n/N. Am. v. 
Occupational Safety & Health Admin., 727 F.2d 415, 427 (5th Cir. 1984) 
(``[M]uch of the claimed benefit could be obtained simply by enforcing 
the current standard.'').
---------------------------------------------------------------------------

    \18\ This adoption includes the citations in the referenced 
section of the Healthcare ETS, which are also included in the docket 
for this ETS.
---------------------------------------------------------------------------

    Through its enforcement guidance, OSHA identified a number of 
current standards and regulations that might apply when workers have 
occupational exposure to SARS-CoV-2, most of which are the same 
standards OSHA considered in the Healthcare ETS. (Updated Interim 
Enforcement Response Plan for Coronavirus Disease 2019 (COVID-19)) 
(OSHA, July 7, 2021). OSHA has also cited the Hazard communication 
standard (29 CFR 1910.1200) during COVID-19 investigations. 
Accordingly, a list of


potentially applicable standards and regulations follows:
     29 CFR part 1904, Recording and Reporting Occupational 
Injuries and Illnesses. This regulation requires certain employers to 
keep records of work-related fatalities, injuries, and illnesses and 
report them to the government in specific circumstances.
     29 CFR 1910.132, General requirements--Personal Protective 
Equipment (PPE). This standard requires that appropriate PPE, including 
PPE for eyes, face, head, and extremities, protective clothing, 
respiratory devices, and protective shields and barriers, be provided, 
used, and maintained in a sanitary and reliable condition.
     29 CFR 1910.134, Respiratory protection. This standard 
requires that employers provide, and ensure the use of, appropriate 
respiratory protection when necessary to protect employee health.
     29 CFR 1910.141, Sanitation. This standard applies to 
permanent places of employment and contains, among other requirements, 
general housekeeping and waste disposal requirements.
     29 CFR 1910.145, Specification for accident prevention 
signs and tags. This standard requires the use of biological hazard 
signs and tags, in addition to other types of accident prevention signs 
and tags.
     29 CFR Subpart U--COVID-19 Emergency Temporary Standard. 
The Healthcare ETS, promulgated on June 21, 2021 includes various 
controls (patient screening and management, respirators and other PPE, 
limiting exposure to aerosol-generating procedures, physical 
distancing, physical barriers, cleaning, disinfection, ventilation, 
health screening and medical management, access to vaccination, anti-
retaliation provisions, and medical removal protection) to address the 
grave danger posed by COVID-19 to healthcare workers.
     29 CFR 1910.1020, Access to employee exposure and medical 
records. This standard requires that employers provide employees and 
their designated representatives access to relevant exposure and 
medical records.
     29 CFR 1910.1200, Hazard communication. This standard 
requires employers to keep Safety Data Sheets (SDS) for chemical 
hazards, provide SDSs to employees and their representatives when 
requested, and train employees about those hazards. The standard does 
not apply to biological hazards, but hazard communication becomes an 
issue for the SARS-CoV-2 virus when chemicals are used to disinfect 
surfaces.
    OSHA again finds that none of these existing standards provide for 
the types of workplace controls that are necessary to combat the grave 
danger addressed by this ETS. First, none of the listed potentially 
applicable standards require vaccination against SARS-CoV-2, the most 
efficient and effective control to combat the grave danger posed by the 
virus. (The Bloodborne Pathogen Standard requires that the hepatitis B 
vaccine be made available to certain employees, but that is not that is 
not relevant here, since the hepatitis vaccine provides no protection 
against COVID-19). Nor are the additional safety measures included in 
this ETS--vaccination verification, screening testing, face coverings, 
and medical removal of COVID-19 positive workers-- required by existing 
standards other than OSHA's Healthcare ETS (covering employees exempted 
from this new ETS while the Healthcare ETS is in effect).
    Second, because existing standards do not contain provisions 
specifically targeted at the COVID-19 hazard, it may be difficult for 
employers and employees to determine what particular COVID-19 safety 
measures are required by existing standards, or how the separate 
standards are expected to work together as applied to COVID-19. An ETS 
that contains provisions specifically addressing COVID-19 hazards in 
covered workplaces will provide clear instructions. More certainty will 
lead to more compliance, and more compliance will lead to improved 
protection of employees covered by this standard.
    Third, requirements in some standards may be appropriate for other 
situations but simply do not contemplate COVID-19 and fail to address 
important aspects of the hazard. For example, the general sanitation 
standard requires employers to provide warm water, soap, and towels 
that can be used in hand washing, but does not require disinfection or 
provision of hand sanitizer where handwashing facilities cannot be made 
readily available. See 86 FR 32417. Although the sanitation standard 
might appear at first glance to be relevant here, it simply does not 
require the types of controls that would, even if more rigorously 
enforced, sufficiently reduce the threat of COVID-19 in the workplace. 
As such, OSHA affirms its previous determination that some of the 
above-listed standards--including the sanitation standard--are in 
practice too difficult to apply to the COVID-19 hazard and have never 
been cited in COVID enforcement. 86 FR 32416.
    Fourth, existing recordkeeping and reporting regulations do not 
adequately allow the employer or the agency to assess the full scope of 
COVID-19 workplace exposures and protection. OSHA's general 
recordkeeping regulations were not written with the nature of COVID-19 
transmission or illness in mind. In order to adequately understand and 
thereby control the spread of COVID-19 in the workforce, it is critical 
that the employer has records of employees' vaccination status, and of 
the testing undergone by employees who do not receive vaccination, and 
that it knows of all cases of COVID-19 occurring among employees. 
However, such information is outside of the scope of OSHA's existing 
recordkeeping requirements, which are limited to injuries or illnesses 
that the employer knows to be work-related.
    Moreover, existing reporting regulations do not adequately ensure 
that OSHA has the full picture of the impact of COVID-19 because those 
regulations only require employers to report in-patient 
hospitalizations that occur within 24 hours of the work-related 
incident and to report fatalities that occur within thirty days of the 
work-related incident. 86 FR at 32417. Many COVID-19 infections will 
not result in hospitalization or death until well after these limited 
reporting periods. Under existing regulations, such cases are not 
required to be reported to OSHA, which limits the agency's ability to 
fully understand the impact of COVID-19 on the workforce. 86 FR 32417. 
This ETS includes a provision, paragraph (k), that removes the time 
limitation on reporting for COVID-19 cases.
    In conclusion, OSHA's experience has demonstrated that existing 
standards and regulations are inadequate to address the current COVID-
19 hazard.
b. The General Duty Clause Is Inadequate To Meet the Current Crisis
    Section 5(a)(1) of the OSH Act, or the General Duty Clause, 
provides the general mandate that each employer ``furnish to each of 
[its] employees employment and a place of employment which are free 
from recognized hazards that are causing or are likely to cause death 
or serious physical harm to [its] employees.'' 29 U.S.C. 654(a)(1). For 
General Duty Clause citations to be upheld, OSHA must demonstrate 
elements of proof that are supplementary to, and can be more difficult 
to show than, the elements of proof required for violations of specific 
standards, where a hazard is presumed. Specifically, to prove a 
violation of the General Duty Clause, OSHA needs to



establish--in each individual case--that: (1) An activity or condition 
in the employer's workplace presented a hazard to an employee; (2) the 
hazard was recognized; (3) the hazard was causing or was likely to 
cause death or serious physical harm; and (4) feasible means to 
eliminate or materially reduce the hazard existed. BHC Nw. Psychiatric 
Hosp., LLC v. Sec'y of Labor, 951 F.3d 558, 563 (D.C. Cir. 2020). OSHA 
often relies on the General Duty Clause to fill gaps where specific 
standards do not address a hazard and OSHA enforces it through case-by-
case adjudicative proceedings. See United States v. Strum, 84 F.3d 1, 5 
(1st Cir. 1996).
    OSHA has previously found the General Duty Clause to be inadequate 
to protect employees from dangers posed by infectious agents. In 
promulgating the bloodborne pathogens standard, OSHA explained that 
enforcement under the General Duty Clause was insufficient to protect 
employees from the serious hazards those pathogens present. 56 FR 64007 
(December 6, 1991). In the recently promulgated Healthcare ETS, OSHA 
found that the General Duty Clause was insufficient to protect 
healthcare workers from the grave danger they faced as well. 86 FR 
32418. While OSHA initially attempted to use the General Duty Clause to 
protect employees across all industries from COVID-19-related hazards, 
OSHA's experience has demonstrated that the Clause is grossly 
inadequate to protect employees covered by this ETS from the grave 
danger posed by COVID-19 in the workplace. As explained more fully 
below, OSHA finds this ETS is necessary to protect employees from the 
hazards of COVID-19.
    As an initial matter, the General Duty Clause does not provide 
employers with specific requirements to follow or a roadmap for 
implementing appropriate abatement measures. The ETS, however, provides 
a clear statement of what OSHA expects employers to do to protect 
workers, thus facilitating better compliance. The General Duty Clause 
is so named because it imposes a general duty to keep the workplace 
free of recognized serious hazards; the ETS, in contrast, lays out 
clear requirements for employers to implement vaccination policies 
including vaccination verification, support for employee vaccination, 
screening testing and face coverings for unvaccinated workers, and 
medical removal of COVID-19 positive employees. Conveying obligations 
as clearly and specifically as possible makes it much more likely that 
employers will comply with those obligations and thereby protect 
workers from COVID-19 hazards. See, e.g., Integra Health Mgmt., Inc., 
2019 WL 1142920, at *7 n.10 (No. 13-1124, 2019) (noting that standards 
``give clear notice of what is required of the regulated community''); 
56 FR 64007 (``because the standard is much more specific than the 
current requirements [general standards and the general duty clause], 
employers and employees are given more guidance in carrying out the 
goal of reducing the risks of occupational exposure to bloodborne 
pathogens'').
    Moreover, several characteristics of General Duty Clause 
enforcement actions make them an inadequate means to address hazards 
associated with COVID-19. First, it would be virtually impossible for 
OSHA to require and enforce the most important worker-protective 
elements of the ETS (such as vaccination and testing) under the General 
Duty Clause. Second, OSHA's burden of proof for establishing a General 
Duty Clause violation is heavier than for standards violations. Third, 
promulgating an ETS will enable OSHA to issue more meaningful penalties 
for willful and egregious violations, thus creating effective 
deterrence against employers who intentionally disregard their 
obligations under the Act or demonstrate plain indifference to employee 
safety. As discussed in more detail below, all of these considerations 
demonstrate OSHA's need to promulgate this ETS in order to protect 
unvaccinated workers covered by this standard from hazards posed by 
COVID-19.

The General Duty Clause is ill-suited to requiring employers to adopt 
vaccination and testing policies, like those required by the ETS

    Because the General Duty Clause requires OSHA to establish the 
existence and feasibility of abatement measures that can materially 
reduce a hazard, it is difficult for OSHA to use the clause to require 
specific control measures where an employer is doing something, but not 
what the Secretary has determined is needed to fully address the 
serious hazard. See, e.g., Waldon Health Care Center, 16 BNA OSHC 1052, 
1993 WL 119662 at * (No. 89-2804, 1993) (vacating OSHA citation 
requiring pre-exposure hepatitis B vaccination under General Duty 
Clause by finding that although vaccination would more fully reduce the 
hazard, the employer's chosen means of abatement were sufficient); 
Brown & Root, Inc., Power Plant Div., 8 BNA OSHC 2140, 1980 WL 10668 at 
*5 (No. 76-1296, 1980) (``[T]he employer may defend against a section 
5(a)(1) citation by asserting that it was using a method of abatement 
other than the one suggested by the Secretary.'').
    Further, even where OSHA establishes a violation of the General 
Duty Clause, the employer is under no obligation to implement the 
feasible means of abatement proven by OSHA as part of its prima facie 
case. Cyrus Mines Corp., 11 OSH Cas. (BNA) 1063, 1982 WL 22717, at *4 
(No. 76-616, 1983) (``[The employer] is not required to adopt the 
abatement method suggested by the Secretary, even one found feasible by 
the Commission; it may satisfy its duty to comply with the standard by 
using any feasible method that is appropriate to abate the 
violation.''); Brown & Root, Inc., Power Plant Div., 1980 WL 10668 at 
*5. Thus, even in cases where OSHA prevails, the employer need not 
necessarily implement the specific abatement measure(s) OSHA 
established would materially reduce the hazard. The employer could 
select alternative controls and then it would be up to OSHA, if it 
wished to cite the employer again, to establish that the recognized 
hazard continued to exist and that its preferred controls could 
materially reduce the hazard even further.
    Given the severity and pervasiveness of the COVID-19 hazard, OSHA 
has determined that the specific abatement measures provided in this 
ETS are necessary to protect workers from grave danger. Under the 
General Duty Clause alone, it would be nearly impossible to require 
employers to provide these specific measures, and even then, it could 
only be on a case-by-case enforcement basis. Considering the magnitude 
and ubiquity of the danger that SARS-CoV-2 poses to workers across the 
country, the case-by-case adjudicatory regime set up through the 
General Duty Clause is simply not adequate to combat the risk of severe 
illness and death caused by the virus.
General Duty Clause Citations Impose a Heavy Litigation Burden on OSHA
    Under the General Duty Clause OSHA must prove that there is a 
recognized hazard, i.e., a workplace condition or practice to which 
employees are exposed, creating the potential for death or serious 
physical harm to employees. See SeaWorld of Florida LLC v. Perez, 748 
F.3d 1202, 1207 (D.C. Cir. 2014); Integra Health Management, 2019 WL 
1142920, at *5. Whether a particular workplace condition or practice is 
a ``recognized hazard'' under the General Duty Clause is a question of 
fact that must be decided in each individual case. See SeaWorld of 
Florida LLC, 748 F.3d at 1208. In the case of a COVID-19-related 
citation, this means showing



not just that the virus is a hazard as a general matter--a fairly 
indisputable point--but also that the specific conditions in the cited 
workplace, such as unvaccinated, unmasked employees working in close 
proximity to other employees for extended periods, create a COVID-19-
related hazard.
    In contrast, an OSHA standard that requires or prohibits specific 
conditions or practices establishes the existence of a hazard. See 
Harry C. Crooker & Sons, Inc. v. Occupational Safety & Health Rev. 
Comm'n, 537 F.3d 79, 85 (1st Cir. 2008); Bunge Corp. v. Sec'y of Labor, 
638 F.2d 831, 834 (5th Cir. 1981). Thus, in enforcement proceedings 
under OSHA standards, as opposed to the General Duty Clause, ``the 
Secretary need not prove that the violative conditions are actually 
hazardous.'' Modern Drop Forge Co. v. Sec'y of Labor, 683 F.2d 1105, 
1114 (7th Cir. 1982). With OSHA's finding that the hazard of exposure 
to COVID-19 can exist for unvaccinated workers in all covered 
workplaces (see Grave Danger, Section III.A. of this preamble), the ETS 
will eliminate the burden to repeatedly prove, workplace by workplace, 
the existence of a COVID-19 hazard under the General Duty Clause.
    One of the most significant advantages to standards like the ETS 
that establish the existence of the hazard at the rulemaking stage is 
that the Secretary can require specific abatement measures without 
having to prove that a specific cited workplace is already 
hazardous.\19\ In contrast, as discussed above, under the General Duty 
Clause the Secretary cannot require abatement before proving in the 
enforcement proceeding that an existing condition at the workplace is 
hazardous. For example, in a challenge to OSHA's Grain Handling 
Standard, which was promulgated in part to protect employees from the 
risk of fire and explosion from accumulations of grain dust, the Fifth 
Circuit acknowledged OSHA's inability to effectively protect employees 
from these hazards under the General Duty Clause in upholding, in large 
part, the standard. See Nat'l Grain & Feed Ass'n v. Occupational Safety 
& Health Admin., 866 F.2d 717, 721 (5th Cir. 1988) (noting Secretary's 
difficulty in proving explosion hazards of grain handling under General 
Duty Clause). Although OSHA had attempted to address fire and explosion 
hazards in the grain handling industry under the General Duty Clause, 
``employers generally were successful in arguing that OSHA had not 
proved that the specific condition cited could cause a fire or 
explosion.'' Id. at 721 & n.6 (citing cases holding that OSHA failed to 
establish a fire or explosion hazard under the General Duty Clause). 
The Grain Handling Standard, in contrast, established specific limits 
on accumulations of grain dust based on its combustible and explosive 
nature, and the standard allowed OSHA to cite employers for exceeding 
those limits without the need to prove at the enforcement stage that 
each cited accumulation was likely to cause a fire or explosion. See 
id. at 725-26.
---------------------------------------------------------------------------

    \19\ ``The Act does not wait for an employee to die or become 
injured. It authorizes the promulgation of health and safety 
standards and the issuance of citations in the hope that these will 
act to prevent deaths and injuries from ever occurring.'' Whirlpool 
Corp, v. Marshall, 445 U.S. 1, 12 (1980); see also Arkansas-Best 
Freight Sys., Inc. v. Occupational Safety & Health Rev. Comm'n, 529 
F.2d 649, 653 (8th Cir. 1976) (noting that the ``[OSH] Act is 
intended to prevent the first injury'').
---------------------------------------------------------------------------

    The same logic applies to COVID-19 hazards. Given OSHA's burden 
under the General Duty Clause to prove that conditions at the cited 
workplace are hazardous, it is difficult for OSHA to ensure necessary 
abatement before individual employee lives and health are unnecessarily 
endangered by exposure to COVID-19, despite widespread evidence of the 
grave danger posed by worker exposure to COVID-19. Indeed, despite 
publishing a voluminous collection of COVID-19 guidance online and 
receiving and investigating thousands of complaints, OSHA did not 
believe it could justify the issuance of more than 20 COVID-19 related 
General Duty Clause citations over the entire span of the pandemic so 
far, because of the quantum of proof the Secretary must amass under the 
General Duty Clause. Unlike enforcement under the General Duty Clause, 
this ETS allows OSHA to cite employers for each protective requirement 
they fail to implement without the need to wait for employee infection 
or death to prove in an enforcement proceeding that the particular 
cited workplace was hazardous without that particular measure in place. 
Thus, this ETS, which covers millions of workers nation-wide, is 
significantly preferable to the General Duty Clause with respect to 
such a highly transmissible virus because the inability to prevent a 
single exposure can quickly result in an exponential increase in 
exposures and illnesses or fatalities even at a single worksite.
    An additional limitation of the General Duty Clause is that proving 
that there are feasible means to materially reduce a recognized hazard 
typically requires testimony from an expert witness in each separate 
case, which limits OSHA's ability to prosecute these cases as broadly 
as needed to protect workers, in light of the expense involved. See, 
e.g., Integra Health Management, 2019 WL 1142920, at *13 (requiring 
expert witness to prove proposed abatement measures would materially 
reduce hazard). In contrast, where an OSHA standard specifies the means 
of compliance, the agency has already made the necessary technical 
determinations in the rulemaking and therefore does not need to 
establish feasibility of compliance as part of its prima facie case in 
an enforcement proceeding. See, e.g., A.J. McNulty & Co. v. Sec'y of 
Labor, 283 F.3d 328, 334 (D.C. Cir. 2002); S. Colorado Prestress Co. v. 
Occupational Safety & Health Rev. Comm'n, 586 F.2d 1342, 1351 (10th 
Cir. 1978). Preventing the initial exposure and protecting as many 
workers as quickly as possible is especially critical in the context of 
COVID-19 because, as explained in Grave Danger, Section III.A. of this 
preamble, it can spread so easily in workplaces.

The ETS will also permit OSHA to achieve meaningful deterrence when 
necessary to address willful or egregious failures to protect employees 
against the COVID-19 hazard

    As described above, in contrast to the broad language of the 
General Duty Clause, this ETS will prescribe specific measures 
employers covered by this standard must implement. This specificity 
will make it easier for OSHA to determine whether an employer has 
intentionally disregarded its obligations or exhibited a plain 
indifference to employee safety or health. In such instances, OSHA can 
classify the citations as ``willful,'' allowing it to propose higher 
penalties, with increased deterrent effects. In promulgating the 
Healthcare ETS, OSHA noted that early in the pandemic, shifting 
guidance on the safety measures employers should take to protect their 
employees from COVID-19 created ambiguity regarding employers' specific 
obligations. Thus, OSHA could not readily determine whether a 
particular employer had ``intentionally'' disregarded obligations that 
were not yet clear. And, even as the guidance began to stabilize, 
OSHA's ability to determine ``intentional disregard'' or ``plain 
indifference'' was difficult, for example, when an employer took some 
steps address the COVID-19 hazard. 86 FR 32420. The Healthcare ETS 
largely resolved this issue for employers covered by that standard, by 
laying out clearly what parameters to put in place to protect 
healthcare workers. However, this general challenge persists in OSHA's


attempts at enforcement in other industries.
    Further, OSHA has adopted its ``egregious violation'' policy to 
impose sufficiently large penalties that achieve appropriate deterrence 
against bad actor employers who willfully disregard their obligation to 
protect their employees when certain aggravating circumstances are 
present, such as a large number of injuries or illnesses, bad faith, or 
an extensive history of noncompliance (OSHA Directive CPL 02-00-080 
(October 21, 1990)). Its purpose is to increase the deterrent impact of 
OSHA's enforcement activity. This policy utilizes OSHA's authority to 
issue a separate penalty for each instance of noncompliance with an 
OSHA standard, such as each employee lacking the same required 
protections, or each workstation lacking the same required controls. It 
can be more difficult to use this policy under the General Duty Clause 
because the Fifth Circuit and the Occupational Safety and Health Review 
Commission have held that, under the General Duty Clause, OSHA may only 
cite a hazardous condition once, regardless of its scope or the number 
of workers affected. Reich v. Arcadian Corp., 110 F.3d 1192, 1199 (5th 
Cir. 1997). Thus, even where OSHA finds that an employer willfully 
failed to protect a large number of employees from a COVID-19 hazard, 
OSHA might not be able to cite the employer on a per-instance basis for 
failing to protect each of its employees. The provisions of this ETS 
have been intentionally drafted to make clear OSHA's authority to 
separately cite employers for each instance of the employer's failure 
to protect employees and for each affected employee, where appropriate.
    By providing needed clarity, the ETS will facilitate ``willful'' 
and ``egregious'' determinations that are critical enforcement tools 
OSHA can use to adequately address violations by employers who have 
shown a conscious disregard for the health and safety of their workers 
in response to the pandemic. Without the necessary clarity, OSHA has 
been limited in its ability to impose penalties high enough to motivate 
the very large employers who are unlikely to be deterred by penalty 
assessments of tens of thousands of dollars, but whose noncompliance 
can endanger thousands of workers. Indeed, OSHA has only been able to 
issue two COVID-19-related ``willful'' citations and no ``egregious'' 
citations since the start of the pandemic because of the challenges 
described above.
    For all of the reasons described above, and after over a year of 
attempting to use the General Duty Clause to address this widespread 
hazard, OSHA finds that the General Duty Clause is not an adequate 
enforcement tool to protect employees covered by this standard from the 
grave danger posed by COVID-19.
c. OSHA and Other Entity Guidance Is Insufficient
    OSHA has issued numerous non-mandatory guidance products to advise 
employers on how to protect workers from SARS-CoV-2 infection (see 
https://www.osha.gov/coronavirus). Even the most comprehensive guidance 
makes clear, as it must, that the guidance itself imposes no new legal 
obligations, and that its recommendations are ``advisory in nature.'' 
(See OSHA's online guidance, Protecting Workers: Guidance on Mitigating 
and Preventing the Spread of COVID-19 in the Workplace (OSHA, Updated 
August 13, 2021); and OSHA's earlier 35-page booklet, Guidance on 
Preparing Workplaces for COVID-19, (OSHA, March 9, 2020)). This 
guidance, as well as guidance products issued by other government 
agencies and organizations, including the CDC, the Centers for Medicare 
& Medicaid Services (CMS), the Institute of Medicine (IOM), and the 
World Health Organization (WHO), help protect employees to the extent 
that employers voluntarily choose to implement the practices they 
recommend. Unfortunately, OSHA's experience and the continued spread of 
COVID-19 throughout the country shows that does not happen consistently 
or rigorously enough, resulting in inadequate protection for employees. 
For example, the CDC has strongly recommended vaccination since 
vaccines became widely available earlier in the year, but many 
employees have yet to take this simple step, which would protect 
themselves and their co-workers from the danger of COVID-19.
    As documented in numerous peer-reviewed scientific publications, 
CDC, IOM, and WHO have recognized a lack of compliance with non-
mandatory recommended infection-control practices (Siegel et al., 2007; 
IOM, 2009; WHO, 2009). As noted in the preamble to the Healthcare ETS, 
OSHA was aware of these findings when it previously concluded that an 
ETS was not necessary, but at the time of that conclusion, the agency 
erroneously believed that it would be able to effectively use the non-
mandatory guidance as a basis for establishing the mandatory 
requirements of the General Duty Clause, and informing employers of 
their compliance obligations under existing standards. 86 FR 32421. As 
explained above, that has not proven to be an effective strategy. 
Moreover, when OSHA made its initial necessity determination at the 
beginning of the pandemic, it made an assumption that given the 
unprecedented nature of the COVID-19 pandemic, there would be an 
unusual level of widespread voluntary compliance by the regulated 
community with COVID-19-related safety guidelines. (See, e.g., DOL, May 
29, 2020 at 20 (observing that ``[n]ever in the last century have the 
American people been as mindful, wary, and cautious about a health risk 
as they are now with respect to COVID-19,'' and that many ``protective 
measures are being implemented voluntarily, as reflected in a plethora 
of industry guidelines, company-specific plans, and other sources'')).
    Since that time, however, developments have led OSHA to conclude 
that the same uneven compliance documented by CDC, IOM, and WHO is also 
occurring for the COVID-19 guidance issued by OSHA and other agencies. 
For example, rising ``COVID fatigue'' or ``pandemic fatigue'' has been 
reported for nearly a year already--i.e., a decrease in voluntary use 
of COVID-19 mitigation measures over time (Meichtry et al., October 26, 
2020; Silva and Martin, November 14, 2020; Belanger and Leander, 
December 9, 2020; Millard, February 18, 2021). Other reasons that 
people have not followed COVID-19 guidance include fear of financial 
loss; skepticism about the danger posed by COVID-19; and even a simple 
human tendency, called ``psychological reactance,'' to resist curbs on 
personal freedoms, i.e., an urge to do the opposite of what somebody 
tells you to do (Belanger and Leander, December 9, 2020; Markman, April 
20, 2020). OSHA is seeing evidence of these trends in its COVID-19 
enforcement. For example, although OSHA has issued guidance since the 
spring of 2020 encouraging the use of physical distancing and barriers 
as a means of protecting employees at fixed work locations, there have 
been a number of news reports indicating that employers ignore that 
guidance (Romo, November 19, 2020; Richards, May 5, 2020; Lynch, July 
9, 2020). This was evidenced by a cross-sectional study performed from 
late summer to early fall of 2020 in New York and New Jersey that found 
non-compliance and widespread inconsistencies in COVID-19 response 
programs (Koshy et al., February 4, 2021). Indeed, OSHA continues to 
receive complaints and referrals attesting to such workplace practices.


(OSHA, October 17, 2021). Worse, some employers must now deal with 
employees who not only have yet to be vaccinated but compound the 
danger by hiding their unvaccinated status and declining to wear source 
protection that would identify them as unvaccinated, even though it 
could provide some protection to their coworkers, in workplaces where 
there is a stigma attached to being unvaccinated. (Ember and Murphy 
Marcos, August 7, 2021). This ETS contains notification and vaccine 
verification requirements that address these avoidant behaviors and 
mitigate the hazard of undisclosed exposure and transmission (see the 
Summary and Explanation for paragraphs (e), (g), and (h), Sections 
VI.E., VI.G., and VI.H. of this preamble).
    OSHA's more recent guidance update encourages employers to 
facilitate employee vaccination by providing paid time off and 
encourages testing and masks for unvaccinated workers. However, as 
discussed previously, vaccination rates remain inconsistent across the 
country and have slowed significantly since the spring of 2021. And 
infection rates remain high, especially among the unvaccinated. It is 
clear, as discussed previously, that voluntary self-regulation by 
employers will not sufficiently reduce the danger that COVID-19 poses 
in workplaces covered by this standard. As noted in the White House 
Report on vaccination requirements released on October 7, at this time 
only 25% of businesses have vaccine mandates in place (White House, 
October 7, 2021). Since this ETS and other federal efforts to require 
vaccination were announced more private and public sector institutions 
have begun to prepare to implement vaccination requirements, further 
demonstrating the need for this rule as an impetus for employer action 
(White House, October 7, 2021).
    The high number of COVID-19-related complaints and reports that 
OSHA continues to receive on a regular basis suggests a lack of 
widespread compliance with existing voluntary guidance: From March 2020 
to October 2021, OSHA has continued to receive hundreds of COVID-19-
related complaints every month, including over 400 complaints during 
the month of August 2021, and over 450 complaints to date in the month 
of September (OSHA, October 11, 2021). And, as of October 17, OSHA has 
received 223 additional COVID-19-related complaints. (OSHA, October 17, 
2021). If guidance were followed more strictly, or if there were enough 
voluntary compliance with steps to prevent illness, OSHA would expect 
to see a significant reduction in COVID-19-related complaints from 
employees.
    The dramatic increases in the percentage of the population that 
contracted the virus during the summer of 2021 indicates a continued 
risk of COVID-19 transmission in workplace settings (for more 
information on the prevalence of COVID-19 see Grave Danger, Section 
III.A. of this preamble) despite OSHA's publication of numerous 
specific and comprehensive guidance documents. OSHA has found that 
neither reliance on voluntary action by employers nor OSHA non-
mandatory guidance is an adequate substitute for specific, mandatory 
workplace standards at the federal level. Public Citizen v. Auchter, 
702 F.2d 1150 at 1153 (voluntary action by employers ``alerted and 
responsive'' to new health data is not an adequate substitute for 
government action).
d. A Uniform Nationwide Response to the Pandemic Is Necessary To 
Protect Workers
    As the pandemic has continued in the United States, there has been 
increasing recognition of the need for a more consistent national 
approach (GAO, September, 2020; Budryk, November 17, 2020; Horsley, May 
1, 2020; DOL OIG, February 25, 2021). Many employers have advised OSHA 
that they would welcome a nationwide ETS. For example, in its October 
9, 2020 petition for a COVID-19 ETS, ORCHSE Strategies, LLC explained 
that it is ``imperative'' that OSHA issue an ETS to provide employers 
one standardized set of requirements to address safety and health for 
their workers (ORCHSE, October 9, 2020). This group of prominent 
business representatives explained that an ETS would eliminate 
confusion and unnecessary burden on workplaces that are struggling to 
understand how best to protect their employees in the face of confusing 
and differing requirements across states and localities.
    The lack of a national standard on this hazard has led to 
increasing imbalance in state and local regulation, a problem that OSHA 
already identified as concerning in its Healthcare ETS. See 86 FR 32413 
(``The resulting patchwork of state and local regulations led to 
inadequate and varying levels of protection for workers across the 
country, and has caused problems for many employees and businesses.'') 
Since the Healthcare ETS was published, states and localities have 
taken increasingly more divergent approaches to COVID-19 vaccination, 
vaccination verification, screening testing, and the use of face 
coverings in the workplace. Currently, the spectrum ranges from states 
and localities requiring vaccine mandates and face coverings to states 
prohibiting or restricting them, with many states falling somewhere in 
between. Due to uneven approaches to vaccination across the country, 
states with the lowest rates of vaccination have COVID-19 infection 
rates four times as high as in states with the highest vaccine rates. 
(Leonhardt, September 7, 2021). Given that thousands of working age 
people continue to be infected with COVID-19 each week, many of whom 
will become hospitalized or die, OSHA recognizes that a patchwork 
approach to worker safety has not been successful in mitigating this 
infectious disease outbreak (CDC, October 18, 2021--Cases, By Age). It 
has become clear that a Federal standard, by way of this ETS, is 
necessary to provide clear and consistent protection to employees 
across the country. As explained in Pertinent Legal Authority (Section 
II. of this preamble) and the Summary and Explanation for paragraph (a) 
(Section VI.A. of this preamble), OSHA has the authority to 
comprehensively address the issue(s) described in this ETS, and the 
standard is intended to preempt conflicting state and local laws.
    In sum, based on its enforcement experience during the pandemic to 
date, OSHA concludes that continued reliance on existing standards and 
regulations, the General Duty Clause, and guidance, in lieu of an ETS, 
is not adequate to protect unvaccinated employees from the grave danger 
of being infected by, and suffering death or serious health 
consequences from, COVID-19.

IV. Conclusion
    This pandemic continues to take a massive toll on American society, 
and addressing it requires a comprehensive national response. This ETS 
is part of that response. OSHA shares the nation's hope for the promise 
of recovery created by the vaccines. But in the meantime, it recognizes 
that we have not yet succeeded in defeating the virus, and that many 
workers across the country are in grave danger. Therefore, this ETS, 
with mitigation measures emphasizing worker vaccination, is necessary. 
Although OSHA finds it necessary to institute specific mitigation 
measures for the immediate future, the agency can adjust as conditions 
change. Even after issuing an ETS, OSHA retains the flexibility to 
update the ETS to adjust to the subsequent evolution of CDC workplace 
guidance. This ETS addresses (and incorporates as a main component) the 
major development in infection control over the last year--the 
development and growing implementation of COVID-19 vaccines. Going 
forward, further developments can be addressed through OSHA's


authority to modify the ETS if needed, or to terminate it entirely if 
vaccination and other efforts end the current emergency. However, at 
this point in time, the available evidence indicates that the ETS is 
necessary to protect unvaccinated employees across the country from the 
grave danger of COVID-19.

IV. Feasibility

A. Technological Feasibility

    This section presents an overview of the technological feasibility 
assessment for OSHA's Emergency Temporary Standard (ETS) for COVID-19 
that requires all employers with 100 or more employees to ensure that 
all employees are fully vaccinated unless they implement a policy 
requiring employees to undergo testing for COVID-19 at least once every 
seven days and wear face coverings.
    Technological feasibility has been interpreted broadly to mean 
``capable of being done'' (Am. Textile Mfrs. Inst. v. Donovan, 452 U.S. 
490, 509-510 (1981)). A standard is technologically feasible if the 
protective measures it requires already exist, can be brought into 
existence with available technology, or can be created with technology 
that can reasonably be expected to be developed, i.e., technology that 
``looms on today's horizon'' (United Steelworkers of Am., AFL-CIO-CLC 
v. Marshall, 647 F.2d 1189, 1272 (D.C. Cir. 1980) (Lead I)); Amer. Iron 
& Steel Inst. v. OSHA, 939 F.2d 975, 980 (D.C. Cir. 1991) (Lead II); 
American Iron and Steel Inst. v. OSHA, 577 F.2d 825 (3d Cir. 1978)). 
Courts have also interpreted technological feasibility to mean that a 
typical firm in each affected industry or application group will 
reasonably be able to implement the requirements of the standard in 
most operations most of the time (see Public Citizen v. OSHA, 557 F.3d 
165 (3d Cir. 2009); Lead I, 647 F.2d at 1272; Lead II, 939 F.2d at 
990).
    OSHA issued an ETS in June 2021 to protect healthcare and 
healthcare support employees in covered healthcare settings from 
exposure to SARS-CoV-2. See 86 FR 32376 (June 21, 2021) (Healthcare 
ETS). OSHA found the requirements in that ETS to be technologically 
feasible, including a requirement for employers to pay for vaccination 
of employees that is very similar to the requirement in this new ETS. 
OSHA's finding that the Healthcare ETS was technologically feasible was 
primarily based on available evidence showing that most healthcare 
employers, and employers across all industry sectors, had already 
implemented, or were in process of implementing, procedures similar to 
those required by the Healthcare ETS. Similarly, OSHA's feasibility 
findings for this ETS are based on evidence that vaccination and 
testing policies, along with the use of face coverings consistent with 
recommendations from the CDC, have been implemented in multiple 
industry sectors as testing and vaccinations were made more widely 
available during the course of the pandemic.
    As discussed in Summary and Explanation (Section VI. of this 
preamble), this ETS for vaccination and testing applies to all 
employers with 100 or more employees, except as noted here. It does not 
apply to workplaces covered under the Safer Federal Workforce Task 
Force COVID-19 Workplace Safety: Guidance for Federal Contractors and 
Subcontractors or settings where any employee provides healthcare 
services or healthcare support services when subject to the 
requirements of the Healthcare ETS (29 CFR 1910.502). It also does not 
apply to employees who do not report to a workplace where other 
individuals such as coworkers or customers are present, employees while 
they are working from home, or employees who work exclusively outdoors.
    As noted above, OSHA has the legal duty to demonstrate that the 
average employer covered by this ETS can comply with that standard in 
most operations most of the time. This legal analysis is therefore 
focused solely on whether employers with 100 or more employees can 
comply with the standard. OSHA's rationale for that scope threshold of 
100 or more employees is explained in the Summary and Explanation for 
paragraph (b), Section VI.B. of this preamble.
    As discussed below, OSHA finds no technological feasibility 
barriers related to compliance with the requirements in the ETS. These 
requirements include establishing and implementing a written mandatory 
COVID-19 vaccination policy or alternative policy requiring testing and 
face coverings; determining employee vaccination status; supporting 
employee vaccination by providing paid time for vaccination and time 
off for recovery; ensuring that employees who are not fully vaccinated 
are tested for COVID-19 at least once every seven days and wear face 
coverings; and recordkeeping for employee vaccination status and 
testing.
    OSHA reviewed numerous large-scale employer surveys and vaccination 
and testing policies developed by employers, public health 
organizations, trade association, and local, state, and federal 
governmental bodies. While OSHA discusses several examples of these 
plans and policies below,\20\ OSHA's feasibility determination is based 
on all evidence in the rulemaking record. The majority of the survey 
data and other publicly available material that OSHA reviewed pertains 
to large employers with 100 or more employees.
---------------------------------------------------------------------------

    \20\ While OSHA references several employers' policies, this is 
not intended to serve as an endorsement of those plans or an 
indication that those plans comply with the ETS. Rather, the plans 
and best practice documents show that developing and implementing 
policies to address employee COVID-19 vaccination in various 
workplaces is capable of being done in a variety of industries, and 
therefore, compliance with the ETS is technologically feasible.
---------------------------------------------------------------------------

    Additionally, OSHA thoroughly reviewed current and future 
projections of the availability of COVID-19 tests, testing supplies, 
and laboratory capacity. Based on a review of vaccination and testing 
policies among large employers, OSHA has determined that most employers 
covered by this standard across a wide range of industries have either 
already implemented vaccination and testing programs and require 
unvaccinated employees to wear face coverings, or are capable of 
implementing programs that comply with the requirements in the ETS most 
of the time. OSHA therefore finds that the standard is technologically 
feasible.
I. Employer Policy on Vaccination
    Paragraph (d)(1) of the ETS requires each covered employer to 
establish and implement a written mandatory vaccination policy unless 
the employer adopts an alternative policy requiring COVID-19 testing 
and face coverings for unvaccinated employees, which is discussed 
later. To meet the definition of ``mandatory vaccination policy'' under 
paragraph (c), the policy must require: Vaccination of all employees, 
including all new employees as soon as practicable, other than those 
employees (1) for whom a vaccine is medically contraindicated, (2) for 
whom medical necessity requires a delay in vaccination, or (3) those 
legally entitled to a reasonable accommodation under federal civil 
rights laws because they have a disability or sincerely-held religious 
beliefs, practices, or observances that conflict with the vaccination 
requirement.
    OSHA requires employers to implement a mandatory vaccination 
requirement, but provides an exemption for an alternative policy that 
allows employees to choose either to be fully vaccinated or to be 
regularly tested and wear a face covering. This compliance options mean 
that the ETS is

technologically feasible if employers across various industries are 
capable of implementing either policy, but nevertheless OSHA analyzes 
both employer policy options to demonstrate that there are no 
significant technological barriers to either approach.
    OSHA reviewed several large-scale employer surveys related to 
vaccination policies across the country covering a wide range of 
industry sectors. Surveys conducted by Arizona State University (ASU) 
and the World Economic Forum (WEF), called COVID-19 Workplace Commons--
Keeping Workers Well, show that most employers already have some type 
of vaccination policy, with more than 60 percent of surveyed employers 
requiring vaccinations for some or all employees. These survey results 
further support OSHA's determination that the vaccination policy 
requirement is feasible.
    The ASU WEF workplace COVID-19 surveys collected information from 
employers across industry sectors about their response to the COVID-19 
pandemic. The results and responses from more than 1,400 companies are 
publicly available through the ASU College of Health Solutions web page 
COVID-19 Diagnostics Commons (ASU, October 5, 2021). Case studies from 
employers are also available within the interactive dashboard on that 
web page. The surveys consisted of numerous questions about workplace 
pandemic response, including questions related to vaccination policies 
and testing unvaccinated employees.
    The most recent COVID-19 survey data was collected between August 
2, 2021 and August 20, 2021 and reported in September 2021 (accessible 
through the COVID-19 Workplace Commons). More than 1,400 companies 
operating 1143 facilities in 23 industry sectors were part of the 
survey, the majority of which are companies of the size covered by the 
ETS. Ninety percent of facilities surveyed had 100 or more employees at 
their facilities, and 56% had more than 100 but less than 1,000 
employees at their facilities. The industry sectors surveyed include: 
Technology and software; business and professional services; 
manufacturing; construction; healthcare, hospitals, and clinics; retail 
stores; retail food stores; consumer retail service; energy and 
utilities; nonprofit organizations; education (colleges and 
universities); education (pre-K to 12); real estate and property 
management; agriculture and food production; healthcare services; media 
and entertainment; government and quasi-public; biotech, 
pharmaceuticals, and diagnostics; restaurants and food service; hotels 
and casinos; transportation, distribution, and logistics; consumer 
transportation; and recreation (ASU WEF, September 2021).
    The survey responses related to vaccination policies support OSHA's 
determination that it is feasible for covered employers to implement 
mandatory COVID-19 vaccination policies. The survey results showed that 
45% of employers surveyed require all employees to be vaccinated 
against COVID-19, and an additional 16% require some of its employees 
to be vaccinated against COVID-19. (ASU WEF, September 2021). Only 
three percent of employers surveyed did not have a vaccination policy 
at the time (ASU WEF, September 2021). While this survey covers a wide 
range of industries it may not represent the percentage of companies 
implementing mandatory vaccination policies in general populations but 
for the feasibility purposes it demonstrates that it has and can be 
done.
    OSHA also reviewed slightly older survey data, which, even though 
it shows somewhat lower rates of employer vaccination mandates, still 
supports OSHA's finding that such vaccination polices are feasible. In 
late June 2021, the National Safety Council (NSC) conducted three 
national surveys, one organizational and two workforce, of private 
companies, nonprofits, legal experts, public health professionals, 
medical professionals and government agencies that have addressed 
workforce COVID-19 vaccinations based on best practices and proven 
workplace safety strategies. The survey results show that many 
employers and organizations are currently requiring employees to be 
vaccinated.
    The three surveys were distributed to 300 employers and 
organizations across the country and from a wide range of industries to 
collect data on pandemic response, including implementation of COVID-19 
vaccine policies and testing among their workforce. Of the employers 
and organizations surveyed in June 2021, the NSC found that 20% were 
implementing some form of a worker vaccination requirement. While OSHA 
believes that the ASU WEF surveys (which included more employers and 
are more recent) are better indicators of current employer vaccination 
policies, the NSC surveys also support the feasibility of employer 
vaccination mandates (NSC, September 2021)
    The NSC, in partnership with the Health Action Alliance (HAA) and 
the Centers for Disease Control and Prevention (CDC), have developed a 
multifaceted, comprehensive effort called SAFER, aimed at helping 
employers prioritize health and safety as they develop plans and 
polices for their employees to return to the workplace (NSC, May 17, 
2021). Through SAFER, the NSC and HAA developed a web-based decision 
tool to guide employers on health, legal, and other considerations to 
prioritize the health and safety of workers. Due to the Delta Variant 
surge of new COVID-19 cases across the United States, the NSC and HAA 
revised the SAFER resources, including the online tool, to include 
information about employer requirements for COVID-19 vaccinations. 
These include guides for developing plans and policies to support 
employee vaccination through mandates and incentives; the collection 
and maintenance of COVID-19 vaccination records; and various 
considerations for testing unvaccinated workers. (HAA and NSC, 
September 17, 2021). The availability of these publicly-accessible 
tools to help employers develop vaccination policies further reduces 
any potential barriers for covered employers to establish and implement 
a written policy requiring each employee to be fully vaccinated against 
COVID-19, or alternatively to establish a policy allowing employees to 
choose whether to be fully vaccinated or tested for COVID-19 at least 
every seven days and wear face coverings.
    The HAA maintains an online list of large companies requiring 
vaccinations for all or part of their workforce or customers. OSHA 
reviewed the list of companies, drawn from news reports and employer 
websites, with requirements for COVID-19 vaccination. Most of the 
companies listed require some or all employees to be vaccinated against 
COVID-19 while allowing medical exemptions or reasonable accommodations 
for disability or religious reasons. There are currently 188 listed 
companies across numerous industry sectors, including Amtrak, Deloitte, 
Google, The Walt Disney Company, Walmart, and the U.S. Chamber of 
Commerce.\21\

---------------------------------------------------------------------------

    While healthcare employers subject to 29 CFR 1910.502 are not 
covered by this ETS, a number of large healthcare employers have 
implemented mandatory vaccine policies. This also shows the feasibility 
of the employers implementing mandatory vaccination requirements, often 
on large scales. According to the American Hospital Association (AHA), 
over 1,800 hospitals


have one or more vaccination requirements in place (Becker's Hospital 
Review, October 11, 2021). Large healthcare employers mandating that 
their employees be vaccinated include Kaiser Permanente, the nation's 
largest integrated, nonprofit health care organization with more than 
216,000 employees and more than 23,000 physicians (Kaiser Permanente, 
August 2, 2021); Trinity Health, one of the largest multi-institutional 
Catholic health care delivery systems in the nation, with more than 
123,000 employees and 90 hospitals in 22 states (Trinity Health, July 
8, 2021); Sanford Health, which operates in 26 states and employs 
nearly 50,000 people (Sanford Health, July 22, 2021); and Genesis 
Health Care, a large U.S. nursing home chain with over 40,000 employees 
working in more than 250 centers across 23 states (Genesis Health Care, 
September 29, 2021).
    Under paragraph (d)(2), if employers do not establish and implement 
a written mandatory vaccination policy, the employer must establish and 
implement a written policy allowing any employees not subject to a 
mandatory vaccination policy to either choose to be fully vaccinated or 
regularly tested for COVID-19 and wear a face covering. A substantial 
number of employers already have such policies in place. For example, 
the ASU WEF survey shows that 30% of employers surveyed require 
unvaccinated employees to participate in mandatory COVID-19 testing and 
30% of employers require face coverings for unvaccinated employees (ASU 
WEF, September 2021).
    OSHA also notes a number of state COVID-19 vaccination 
requirements. In response to the Delta Variant surge, 19 states have 
implemented written COVID-19 vaccination and testing policies for state 
employees and 23 states have done so for healthcare employees (NASHP, 
October 1, 2021). For example, on September 20, 2021, the Colorado 
Department of Public Health and Environment (CDPHE) implemented 
policies requiring state employees and personnel at health care 
facilities and hospitals to be fully vaccinated against COVID-19. All 
state employees must either be fully vaccinated against COVID-19 or 
participate in twice-weekly testing. Employees are allowed work time to 
get tested and administrative or Public Health Emergency Leave to get 
vaccinated. Employees who are not fully vaccinated must wear masks 
inside state facilities when they are around others. On August 30, 
2021, the State Board of Health approved a vaccine requirement for 
personnel in health care settings with high-risk patients. All 
personnel affected by this rule needed to receive their first dose of 
COVID-19 vaccine by September 30, 2021, and must be fully vaccinated by 
October 31, 2021 (CDPHE, September 17, 2021).
    A number of local governments have also implemented policies 
requiring COVID-19 vaccination or testing for employees. For example, 
the Fulton County Board of Commissioners in Georgia recently approved a 
``Vax or Test'' policy requiring employees to get vaccinated or tested 
for COVID-19 each week. Since September 6, 2021, Fulton County has 
required all County employees, as a condition of employment, to either 
be vaccinated against COVID-19 or be tested weekly for COVID-19 unless 
an employee is granted a reasonable accommodation (Fulton County 
Government, September 03, 2021). The multitude of local, state, and 
employer vaccination or testing mandates across the country support 
OSHA's finding that such policies are feasible.
II. Determining Employee Vaccination Status
    Paragraph (e) of the ETS requires employers to determine the 
vaccination status of each employee. Employers must require employees 
to provide an acceptable proof of vaccination status, including whether 
they are fully or partially vaccinated. As discussed in Summary and 
Explanation (Section VI. of this preamble), acceptable proof of 
vaccination status is: (i) The record of immunization from a health 
care provider or pharmacy; (ii) a copy of the COVID-19 Vaccination 
Record Card; (iii) a copy of medical records documenting the 
vaccination; (iv) a copy of immunization records from a public health, 
state, or tribal immunization information system; or a copy of any 
other official documentation that contains the type of vaccine 
administered, date(s) of administration, and the name of the health 
care professional(s) or clinic site(s) administering the vaccine(s). A 
signed and dated employee attestation is acceptable in instances when 
an employee is unable to produce proof of vaccination. Given the 
attestation option, there are no technological barriers to the 
provision for proof of vaccination status. As discussed below, many 
employers requiring proof of vaccination have successfully implemented 
such policies even without allowing the flexibility of the attestation 
option.
    The employer must maintain a record and a roster of each employee's 
vaccination status. This information is subject to applicable legal 
requirements for confidentiality of medical information. These records 
must be preserved while the ETS is in effect. OSHA is not aware of any 
technological challenges that the large employers covered by this ETS 
would face with respect to collecting and maintaining records. This is 
a performance-based requirement, meaning that employers have the 
flexibility to structure their systems to fit within current systems, 
such as those relating to personnel records, tax records, and other 
sensitive or confidential records gathered and maintained by large 
employers.
    A number of the surveys discussed above also show that most 
employers with vaccine mandates require proof of vaccination. For 
example, ASU WEF workplace COVID-19 survey from fall 2021 found that 
60% of employers that required vaccinations also required proof of 
vaccination from employees. The NSC study from June 2021 found that 45% 
of employers with COVID-19 vaccination requirements required proof of 
vaccination, such as submitting a copy of the COVID-19 vaccination 
card. An additional 30% of employers surveyed verify employee 
vaccination status through self-reporting based on the honor system.
    Additionally, a large-scale survey conducted by the Willis Towers 
Watson consulting firm between August 18 and 25, 2021, showed that a 
majority of employers currently track their employees' vaccination 
status. Nearly one thousand employers responded to this survey, and 
they collectively employ 9.7 million workers from industries across the 
public and private sectors including manufacturing, general services, 
wholesale and retail, IT and telecom, healthcare, financial services, 
energy and utilities, and public sector and education (Willis Towers 
Watson, June 23, 2021). Nearly six in 10 (59%) currently track their 
workers' vaccination status and another 19% are planning or considering 
doing so later this year. A majority (62%) of those employers who 
currently track their workers' vaccination status require proof of 
vaccination, such as CDC vaccination cards, while 36% rely on employees 
to self-report (Willis Towers Watson, September 1, 2021).
    Other evidence in the record also supports the feasibility both of 
gathering proof of vaccination and determining employees' vaccination 
status. Many large employers with vaccination policies require 
employees to submit proof of vaccination. For example, Tyson Foods 
requires employees to submit proof of vaccination to Tyson


Foods Vaccination Verification Program in order to qualify for the 
company's vaccination incentive (Tyson Foods, August 3, 2021). 
Similarly, Capital One bank requires all employees, contractors, 
vendors, and visitors to Capital One facilities to show proof of 
vaccination. (Capital One, August 11, 2021). The International Union of 
Painters and Allied Trades (IUPAT), which represents 140,000 
craftspeople in the U.S. and Canada and has implemented vaccine 
requirements for its members, also requires all of its own non-
bargaining unit office and field employees to show proof of 
vaccination. (IUPAT, May 10, 2021).
    CVS Health, a health conglomerate with more than 300,000 employees, 
including more than 40,000 physicians, pharmacists, nurses and nurse 
practitioners, has mandated COVID-19 vaccination for its nurses, 
pharmacists and other employees who interact with patients and requires 
proof of vaccination for those employees (CVS Health, August 23, 2021).
    The surveys and employer policies reviewed by OSHA all support the 
agency's finding that it is feasible for employers to determine their 
employees' vaccination status and collect proof of vaccination.
III. Providing Support for Vaccination
    Paragraph (f) of the ETS requires employers to support COVID-19 
vaccination for each employee by providing a reasonable amount of time 
to each employee for vaccination and reasonable time and paid sick 
leave to each employee for side effects experienced following 
vaccination. The feasibility of paying for the time is addressed in 
OSHA's economic analysis.
    This technological feasibility determination focuses on whether 
employers would encounter obstacles in implementing payment policies 
that would make this requirement infeasible for the large employers 
covered by this ETS. OSHA has determined that there are no such 
obstacles. Most significantly, OSHA has already required this type of 
system for employers covered by the Healthcare ETS and nearly four 
months after that ETS took effect, OSHA is not aware that employers 
covered by that ETS experienced any technological compliance 
difficulties with respect to that requirement. In addition, many 
employers have already implemented policies such as those required to 
comply with this new ETS as a way of incentivizing employee 
vaccination. For example, the ASU WEF workplace COVID-19 survey from 
fall 2021 found that 60% of employers surveyed offered incentives for 
employees to be vaccinated. These incentives ranged from additional 
paid time off, cash, the ability to bypass regular testing and/or daily 
health screening requirements, and gifts. Eighteen percent of surveyed 
employers already provide additional time off for COVID-19 vaccination. 
Moreover, the NSC survey found that 86% of surveyed organizations had 
implemented policies such as paid time off, assistance with scheduling 
and transportation, and/or onsite vaccination.
    OSHA's review of plans and best practice documents from the HAA 
registry and from other publicly-available sources also inform OSHA's 
finding that it is feasible for large employers to support employee 
vaccination (HAA, October 10, 2021). As part of this review, OSHA 
analyzed the ways that employers are currently supporting employee 
vaccination. One employer in the restaurant industry, the Fifty/50 
Group, a Chicago-based restaurant group comprised of 14 establishments 
that requires employees to be fully vaccinated, offers paid time off 
for anyone getting a vaccine or feeling the mild after-effects. (Fifty/
50 Group, May 18, 2021). Another employer in the animal slaughtering 
and processing industry, Tyson Foods, requires COVID-19 vaccinations 
for its U.S. workforce and also offers $200 and up to four hours of 
regular pay if employees are vaccinated outside of their normal shift 
or through an external source (Tyson Foods, August 3, 2021). In 
addition, Tyson Foods supports onsite vaccination events in 
collaboration with local health departments and healthcare providers to 
improve accessibility to vaccination. Tyson Foods has hosted more than 
100 vaccination events at its locations across the country.
    The evidence in the record demonstrates that many employers are 
already offering the types of vaccination support required by paragraph 
(f). Combined with OSHA's previous finding for a similar provision in 
the Healthcare ETS and the lack of compliance difficulties reported 
while that ETS has been in effect, OSHA therefore finds this 
requirement is technologically feasible.
IV. COVID-19 Testing for Employees Who Are Not Fully Vaccinated
    Paragraph (g) of the ETS requires employers to ensure that 
employees who are not fully vaccinated and who report at least once 
every seven days to a workplace where other individuals such as 
coworkers or customers are present are: (1) Tested for COVID-19 at 
least once every seven days; and (2) provide documentation of the most 
recent COVID-19 test result to the employer no later than the seventh 
day following the date the employee last provided a test result. 
Employers must also ensure that employees who are not fully vaccinated 
and do not report during a period of seven or more days to a workplace 
where other individuals are present are: (1) Tested for COVID-19 within 
seven days prior to returning to the workplace; and (2) provide 
documentation of that test result upon return to the workplace.
    Employees who are not fully vaccinated must be tested with a COVID-
19 test, which is a test for SARS-CoV-2 that is: (i) Cleared, approved, 
or authorized, including in an Emergency Use Authorization (EUA) by the 
U.S. Food and Drug Administration (FDA) to detect current infection 
with the SARS-CoV-2 virus (e.g., a viral test); (ii) administered in 
accordance with the authorized instructions; and (iii) not both self-
administered and self-read unless observed by the employer or an 
authorized telehealth proctor. Examples of tests that satisfy this 
requirement include tests with specimens that are processed by a 
laboratory (including home or on-site collected specimens which are 
processed either individually or as pooled specimens), proctored over-
the-counter tests, point of care tests, and tests where specimen 
collection is either done or observed by an employer.
    COVID-19 testing has become more widely available throughout the 
pandemic and as of September 2021, the FDA has authorized approximately 
250 tests and collection kits that diagnose current infection with the 
SARS- CoV-2 virus and may be acceptable under the ETS (FDA, September 
10, 2021), and by October 1, 2021, the number of EUAs issued had grown 
to 324 (FDA, October 1, 2021). The ETS permits compliance through use 
of a wide range of FDA-authorized tests that are readily available, so 
there is little doubt that testing itself is technologically feasible.
    This technological feasibility analysis therefore focuses on 
whether testing will continue to be readily available in quantities 
sufficient to meet the potential increase in testing demand while this 
ETS is in place. Given the wide variety of tests that can be used to 
comply with this ETS and OSHA's review of information about the 
existing manufacturing and distribution capabilities of test 
manufacturers, the agency does not anticipate feasibility issues 
related to ensuring that


employees can get access to one of the acceptable tests within the time 
frames required by the ETS.
a. Brief Overview of Testing and Administration
    COVID-19 tests that are cleared, approved, or authorized, including 
in an Emergency Use Authorization (EUA), by the FDA to detect current 
infection with the SARS-CoV-2 virus (e.g., a viral test) satisfy the 
ETS. FDA-cleared, approved, or authorized molecular diagnostic tests 
and antigen tests are permitted under the ETS when used as authorized 
by the FDA and with a Clinical Laboratory Improvement Amendments of 
1988 (CLIA) certification when appropriate. As described in the Summary 
and Explanation for paragraph (g) (Section VI.G. of this preamble), 
NAATs are a type of molecular test that detect genetic material. As of 
October 14, 2021, the FDA had issued EUAs for 264 molecular COVID-19 
tests including tests specified to be used ``with certain conditions of 
authorization required of the manufacturer and authorized 
laboratories'', 81 of which are authorized for home collection. 
Additionally, the FDA has issued EUAs for 2 OTC molecular COVID-19 test 
kits available without a prescription (FDA, October 14, 2021b).
    NAATs, such as real-time reverse transcription-polymerase chain 
reaction (RT-PCR), have greater accuracy than antigen tests. However, 
most FDA-authorized NAATs need to be processed in a laboratory 
certified under the Clinical Laboratory Improvement Amendments of 1988 
(referred to as a ``CLIA-certified laboratory'') with variable time to 
results (~1-2 days). While the NAAT test is a more reliable test, the 
antigen test is faster and less expensive.
    An antigen test is an in vitro diagnostic test used to detect 
active SARS-CoV-2 infection. As of October 14, 2021, the FDA had issued 
37 EUAs for COVID-19 antigen tests, including eight EUAs for over-the-
counter (OTC) antigen tests that can be used without a prescription 
(FDA, October 14, 2021a).
    Administration of an antigen test that meets the definition of 
COVID-19 test under this ETS falls into one of several categories: OTC 
employee self-tests that are observed by employers or authorized 
telehealth proctors; point-of-care (POC) or OTC tests performed by 
employers with a CLIA certificate of waiver; and other FDA cleared, 
approved, or authorized antigen tests that are analyzed in a CLIA 
certified laboratory setting (FDA, October 14, 2021a). The FDA has 
authorized POC tests that can be used at a place of employment when the 
facility is operating under a CLIA certificate of waiver. A CLIA 
certificate of waiver can be issued by CMS and may, when consistent 
with FDA's authorization, allow a laboratory to run a SARS-CoV-2 test 
outside a high or moderate complexity traditional clinical laboratory 
setting (CDC, September 9, 2021). In accordance with the CLIA 
certificate of waiver, the laboratory or POC testing site must use a 
test authorized for that location, like an FDA EUA POC test, and must 
adhere to the authorized test instructions to avoid human error. 
Certain COVID-19 antigen diagnostic tests can be analyzed on-site 
(where the person took the nasal swab) when that facility is operating 
under a CLIA certificate of waiver, while others must be analyzed in a 
CLIA certified high or moderate complexity laboratory setting. Some 
COVID-19 antigen diagnostic tests are authorized for use at home, 
without the need to send a sample to a laboratory. Antigen tests 
generally return results in approximately 15-30 minutes. The CDC 
provides training materials created by test manufacturers for POC 
antigen testing and reading of results for SARS-CoV-2 (CDC, July 8, 
2021).
    COVID-19 antigen diagnostic tests are found at physician offices; 
urgent care facilities; pharmacies, such as CVS or Walgreens; school 
health clinics; long-term care facilities and nursing homes; temporary 
locations, such as drive-through sites managed by local organizations; 
and other locations across the country (CDC, July 8, 2021; CVS Health, 
October 2021; Walgreens, October 8, 2021). The availability of 
government-offered antigen tests varies by state, and may be free or 
subsidized and accessible without a prescription or physician note 
(RiteAid, October 2021; Walgreens, October 2021; HHS, June 11, 2021). 
The Department of Health and Human Services (HHS) provides a publicly-
available list of community-based testing locations in each state that 
offer free COVID-19 testing for insured and uninsured residents (HHS, 
August 17, 2021). Pharmacies and other locations often provide antigen 
tests by appointment, although some will allow testing for walk-ins 
(CVS Health, September 2021; Walgreens, October 8, 2021). COVID test 
kits are currently available from several on-line retailers (Amazon, 
October 12, 2021).
b. Testing Frequency
    The ASU WEF survey data also supports OSHA's finding that the 
requirement for employees who are not fully vaccinated to be tested at 
least every seven days is feasible. The ASU WEF found that 73% of 
survey surveyed employers (797 employers) had testing policies for 
their workforce, and 76% of those employers had implemented mandatory 
testing requirements. Additionally, 25% of employers with testing 
polices had implemented requirements for routine testing of a portion 
of or the entire workforce, and 41% no longer require testing for fully 
vaccinated employees. Of the employers that test employees, 27% of 
those perform viral testing daily and 46% perform viral test once a 
week. Finally, 38% of companies exclusively administer polymerase chain 
reaction (PCR) tests (PCR tests are a type of NAAT), 17% exclusively 
administer antigen tests, and 45% administer both. Companies administer 
a range of COVID-19 tests and conduct testing at a variety of locations 
(some companies use more than one location). Forty-two percent of 
companies test workers at health testing laboratories, 35% test onsite 
at work, 28% test at hospitals, 23% test at retail pharmacies, 13% test 
at universities, 9% test at home to be sent a lab for evaluation, and 
5% test at home for immediate results (ASU WEF, September 2021).
    OSHA also evaluated evidence of employers' current testing efforts 
by reviewing existing COVID-19 practices developed by employers, trade 
associations, and other organizations. Based on its review, OSHA 
concludes that it is feasible for most covered employees (and therefore 
their employers) to be tested in compliance with the ETS requirements 
for frequency of testing.
    OSHA notes that there are several options for large employers to 
consider if they want to help facilitate testing for employees who are 
not vaccinated. Delta Airlines, for example, currently requires weekly 
COVID-19 testing for all of its employees who are not vaccinated, and 
the company has engaged the Mayo Clinic Laboratories to help design the 
employee testing program, assist in administering diagnostic and 
serology tests, and analyze the results to determine broader trends and 
provide recommendations to Delta's existing policies and procedures 
(Mayo Clinic Laboratories, June 30, 2020). Delta Airlines also operates 
onsite testing in cities with large employee populations including 
Atlanta, Minneapolis, and New York. It recently extended an at-home 
specimen collection option to all U.S. employees, through which Quest 
Diagnostics will send self-collection kits directly to an employee's 
doorstep upon request and support complete laboratory confirmation for 
results (Delta, August 25, 2021).


c. Availability of COVID-19 Tests
    In the spring and early summer months of 2021, demand for tests 
decreased as vaccinations began to increase and the number of COVID-19 
cases declined before the Delta surge and some manufacturers slowed 
production of COVID-19 tests. However, the number of tests performed 
daily has grown considerably over the summer due to the Delta Variant 
surge and re-openings of workplaces and schools. In parallel with the 
Delta surge, COVID-19 testing has increased from a daily average of 
about 450,000 in early July 2021 to about 1.8 million by mid-September 
2021, or roughly 12.6 million per week (JHU, October 8, 2021). This 
data does not include any self-administered OTC tests, which will be 
discussed below.
    OSHA's review of the evidence shows that the increasing rate of 
production of COVID-19 tests is more than adequate to meet rising 
demand related to compliance with the ETS testing option before the 60-
day delayed testing compliance date (see paragraph (m)(2)(ii)). This 
determination is largely based on the number of tests with FDA EUAs 
actively being produced through the National Institutes of Health (NIH) 
Rapid Acceleration of Diagnostics (RADx) initiative described below.
    According to the Johns Hopkins University of Medicine Coronavirus 
Resource Center, the total tests administered in August 2021 was 
approximately 44.4 million (or approximately 11.1 million per week). 
Id. During that same month, the total tests produced by the NIH RADx 
contracts was approximately 121 million (which would average to 30.25 
million per week), resulting in a substantial surplus of available 
tests (NIBIB, September 28, 2021). As discussed in Economic Analysis, 
Section IV.B. of this preamble, Table IV.B.8, OSHA estimates that as 
many as 7.2 million tests may be administered weekly under this 
standard; however, 7.2 million is almost certainly an overestimate 
because it does not exclude employees who are already required to be 
tested by their employers and would continue to be tested at the same 
frequency after the ETS. Even if testing is increased by 7.2 million 
tests per week because of the ETS, that would still mean a surplus of 
nearly 12 million tests per week beyond what would be need to continue 
at current testing levels with the addition of ETS-related tests (30.25 
- 11.1 - 7.2 = 11.95 million surplus per week).
    The total number of tests administered during June, July, and 
August 2021, the period of the summer including the Delta Variant surge 
and other reasons for substantial testing increases such as re-opening 
of schools, was approximately 87 million tests, an average of 
approximately 6.7 million per week (JHU, October 8, 2021). During that 
period, more than 400 million COVID-19 tests were produced through the 
NIH RADx initiative, or roughly 33 million per week. OSHA anticipates 
that this surplus of tests will continue to increase the availability 
of tests that can be used to comply with the ETS.
    The data from the Johns Hopkins Coronavirus Resource Center is 
collected from state and county government sources, so it does not 
include any self-administered OTC tests. Additionally, while all states 
report PCR testing, not all states report antigen testing. 
Nevertheless, the data from Johns Hopkins Coronavirus Resource Center 
is the best available evidence from which to estimate the total number 
of tests administered during a given period of time. Even though the 
number of administered tests reported through the Johns Hopkins 
Coronavirus Resource Center does not include unreported OTC tests, the 
NIH RADx program data shows a large surplus and sufficient additional 
COVID-19 test capacity relative to the number of administered tests 
reported. Additionally, the NIH RADx program will further allow for 
increased test distribution through retail markets and will address any 
increase in demand due to companies that may stockpile tests. This 
increased availability will strengthen test capacity, further enabling 
compliance with the ETS testing provision (NIBIB, September 28, 2021). 
OSHA has determined that even with an estimated additional 7.2 million 
tests administered weekly due to the ETS (see Economic Analysis 
(Section IV.B. of this preamble)), there are sufficient COVID-19 tests 
available to allow for both employers and employees to obtain COVID-19 
tests through a variety of retail sources (e.g., local pharmacies, on-
line purchasing as discussed above).
    Determinations of testing capacity are aggregate measures of 
domestic and global market and supply chains. Throughout the pandemic, 
diagnostic testing capacity has been stressed by the increased demand, 
as some products that are part of a global market cannot adapt by 
simply increasing manufacturing in one country (e.g., laboratory 
instruments), and other products manufactured domestically require 
capital investments to address rising demands (e.g., extraction kits) 
(CRS, February 25, 2021). As discussed below, because of the 
substantial investments made, OSHA projects that the diagnostic testing 
capacity can meet the increased demand due to this ETS.
    OSHA evaluated multiple projections of current and future testing 
capacity and determined that projections related to the NIH initiatives 
discussed below are the most reliable estimates of current and future 
testing capacity for its technological feasibility assessment. Test 
manufacturers receiving NIH, FDA, and Biomedical Advanced Research and 
Development Authority (BARDA) (a component of HHS) funding as part of 
these programs undergo a submission and authorization process where 
their production capacity and pipeline are assessed and production 
quantities are validated. As explained below, as of August 2021, the 
NIH data indicates testing capacity stands at about 30 million tests 
per week, and capacity continues to grow (NIBIB, September 28, 2021). 
OSHA notes that this number underestimates the total number of tests 
available each week, as it only includes companies that have received 
funding for tests and testing supplies through the NIH initiatives 
described below.
    The NIH has identified constraints on testing capacity as an area 
of focus and investment since the beginning of the COVID-19 pandemic, 
and OSHA examined potential constraints on testing capacity as part of 
its feasibility analysis. As described below, massive investments in 
testing capabilities, particularly in underserved areas, have largely 
mitigated issues with the availability of COVID-19 tests. Further, 
testing capacity continues to grow as new tests are developed and 
brought to market and manufacturers can ramp up supply to meet any 
future testing demands if need be.
    The FDA has authorized more than 320 tests and collection kits that 
diagnose current infection with the SARS-CoV-2 virus and may be 
acceptable under the ETS (FDA, October 1, 2021). Among other criteria, 
the standard allows for the use of tests with specimens that are 
processed by a CLIA certified laboratory (including home or on-site 
collected specimens which are processed either individually or as 
pooled specimens), proctored over-the-counter tests, point of care 
tests, and tests where specimen collection and processing is either 
done or observed by an employer. As explained above, many employers 
across various industry sectors have already implemented policies for 
onsite testing. The use of FDA-authorized POC tests by these employers 
would be compliant with the testing provision of the ETS if the entity 
administering the test holds a CLIA


certificate as required by the EUA. COVID-19 OTC tests that are both 
self-administered and self-read by employees do not satisfy the testing 
requirement unless observed by the employer or an authorized telehealth 
proctor. In the event that the employer is merely observing the 
employee conduct a test, a CLIA certificate would not be needed.
    There have been extensive investments, including by the federal 
government, to help ensure that COVID-19 tests are widely available. 
Section 2401 of the American Rescue Plan appropriated $47,800,000 to 
the Secretary of the HHS, to remain available until expended, to carry 
out activities to detect, diagnose, trace, and monitor SARS-CoV-2 and 
COVID-19 infections and related strategies to mitigate the spread of 
COVID-19. Funds were made available to implement a national testing 
strategy; provide technical assistance, guidance, support, and awards 
grants or cooperative agreements to State, local, and territorial 
public health departments; and support the development, manufacturing, 
procurement, distribution, and administration of tests to detect or 
diagnose SARS-CoV-2 and COVID-19; and establish federal, state, local 
and territorial testing capabilities.
    On April 29, 2020, the NIH established the RADx initiative with a 
$1.5 billion investment. The RADx initiative has used this funding to 
speed development of rapid and widely-accessible COVID-19 testing (NIH, 
April 29, 2020). On October 6, 2020, the NIH and BARDA established the 
RADx Technology (RADx-Tech) and RADx Advanced Technology Platforms 
(RADx-ATP) programs to speed innovation in the development, 
commercialization, and implementation of technologies for COVID-19 
testing specifically for late-stage scale-up projects. Through the RADx 
Tech and RADx-ATP programs, the NIH and BARDA have awarded a total of 
$476.4 million in manufacturing expansion contracts supporting a 
combined portfolio of 22 companies in the U.S. (NIH, October 6, 2020).
    These programs have significantly increased testing capacity 
throughout the country. Since being established, RADx has worked 
closely with the FDA, the CDC, and BARDA to move more advanced 
diagnostic technologies swiftly through the development pipeline toward 
commercialization and broad availability. On April 28, 2021, the 
Institute of Electrical and Electronic Engineers (IEEE) dedicated a 
special issue in the Journal of Engineering in Medicine and Biology 
exploring the innovative structure and operation of the RADx Tech 
program and determined that the initiatives had succeeded in 
dramatically increasing COVID-19 testing capacity in the United States. 
The IEEE report found that the RADx Tech/ATP programs, in conjunction 
with BARDA and the FDA, had streamlined and bolstered the national 
COVID-19 testing capacity. At the time of the report, the RADx Tech/ATP 
programs had increased the number of testing makers to 150 companies 
that, as a result of the NIH/BARDA investments, had the capacity to 
produce up to 1.9 million tests per day (IEEE, April 28, 2021).
    The NIH RADx-TECH/ATP initiative entered its second phase on 
September 28, 2021, and at that time the supported companies had 
collectively produced over 500 million tests, received 27 FDA 
authorizations, and developed the first OTC COVID-19 test for use at 
home. These September 2021 investments are supporting late stage 
development of innovative point-of-care and home-based tests, as well 
as improved clinical laboratory tests that will increase the capacity 
of testing in the U.S. A full list of active contracts and supported 
U.S. COVID-19 testing manufacturers can be found on the NIH RADx-TECH/
ATP programs: Phase 2 awards (NIBIB, October 14, 2021).
    The following example shows the NIH RADx EUA pipeline process. On 
May 9, 2020, the FDA authorized the first EUA for a COVID-19 antigen 
test, a new category of tests for use in the ongoing pandemic. Quidel 
was awarded a contract under the NIH RADx TECH/ATP phase 1 initiative 
for the Sofia 2 SARS Antigen FIA for use in high and moderate 
complexity laboratories certified by CLIA, as well as for point-of-care 
testing by facilities operating under a CLIA certificate of waiver 
(FDA, May 9, 2020). On July 31, 2020, Quidel announced that it had 
received a contract for $71 million under the NIH RADx TECH/ATP 
program, phase 1, to accelerate the expansion of its manufacturing 
capacity for production of the SARS-CoV-2 rapid antigen test and 
quickly exceeded that capacity (Quidel Corp., July 31, 2020). On March 
31, 2021, the FDA then authorized a second EUA from Quidel under 
contract with the NIH RADx initiative for the QuickVue At-Home OTC 
COVID-19 Test, another antigen test where certain individuals can 
rapidly collect and test their sample at home, without needing to send 
a sample to a CLIA certifed laboratory for analysis (FDA, March 31, 
2021). Furthermore, based on the success of the Quidel for the Sofia 2 
SARS Antigen FIA increasing production capacity, the NIH granted 
another $70 million contract for manufacturing Capacity Scale-Up for 
Sofia SARS Antigen and Sofia Influenza A+B/SARS FIAs on June 11, 2021 
(FDA, June 11, 2021).
    The RADx-TECH/ATP initiative maintains a dashboard of manufacturer 
testing data from supported U.S. firms. OSHA reviewed the data 
available on the dashboard as part of its determination of feasibility. 
In August 2021, the data showed that U.S. manufacturers supported by 
the NIH RADx-TECH/ATP were producing approximately 30 million tests per 
week (NIBIB, September 28, 2021).
    While consumers in some parts of the country have encountered 
difficulty obtaining rapid at-home tests, on October 4, 2021, the FDA 
granted EUA for the ACON Laboratories Flowflex COVID-19 Home Test, 
which is anticipated to double rapid at-home testing capacity in the 
United States within weeks (and well before compliance dates for 
testing required by this ETS) (FDA, October 4, 2021). By the end of the 
2021 (ahead of the paragraph (g) compliance date), the manufacturer 
plans to produce more than 100 million tests per month and plans to 
produce more than 200 million tests per month by February 2022 (FDA, 
October 4, 2021). On October 6, 2021, the Administration announced a 
plan to buy $1 billion worth of rapid at-home COVID-19 tests; this 
purchase, coupled with the October 4 authorization of the Flowflex 
COVID-19 test, is expected to increase the number of available at-home 
COVID-19 tests to 200 million per month by December 2021 (Washington 
Post, October 6, 2021).
    These investments have had a pronounced impact on the availability 
of testing and employers' use of testing in the workplace. ASU's recent 
report, How Work has Changed: The Lasting Impact of COVID-19 on the 
Workplace, ascribed the jump in the percentage of employers that test 
their employees from 17% in the fall of 2020 to 70% in the fall of 2021 
in large part to the increased availability of testing. In particular, 
the report noted that by the spring of 2021, ``it became relatively 
easy to acquire tests and hire testing service providers. There are 
more labs and companies with EUA's and most have enough capacity that 
there are few shortages.'' (ASU WEF, September 2021).
    Moreover, to ensure a broad, sustained capacity for COVID-19 test 
production, multiple COVID-19 test manufacturers have been mobilized by 
authority of the Defense Production Act. Under the Administration's 
plan to increase COVID-19 testing, the federal


government will directly purchase and distribute 280 million- rapid 
point-of-care and over-the-counter at-home COVID-19 tests, sending 25 
million free at-home rapid tests to community health centers and food 
banks. These actions will provide tests for use by communities to build 
adequate stockpiles, as well as the sustained production to be able to 
scale up production as needed in the future. Additionally, to ensure 
convenient access to free testing, 10,000 pharmacies will be added to 
the Department of Health and Human Services free testing program.
    In response to rising demands for testing, U.S. manufacturers have 
increased production of COVID-19 test kit, reagents, and supplies. 
Advanced Medical Technology Association (AdvaMed), a trade group for 
testing manufacturers, reported that its members are ramping up 
production of rapid point-of-care test supplies to meet demand and that 
laboratory-based testing capacity for test confirmation is strong. 
AdvaMed has created a national COVID-19 Diagnostic Supply Registry of 
COVID-19 test manufacturers that support state and federal governments 
in their pandemic responses. Registry participants are thirteen leading 
diagnostic manufacturers whose tests together comprise approximately 
75-80% of the COVID-19 in vitro diagnostic devices (IVD) on the market 
in the U.S. While these manufacturers produce a majority of molecular 
COVID-19 tests, they do not produce a majority of the total COVID-19 
tests manufactured. These COVID-19 test manufacturers collectively 
shipped approximately 3.8 million tests in July 2021, 8.2 million tests 
in August 2021, and 9.4 million molecular tests for the week ending 
September 4th, 2021 (AdvaMed, September 10, 2021). While these figures 
are not representative of the total weekly testing capacity in the 
U.S., this data demonstrates that testing capacity has grown 
significantly over the past few months and reflects the success 
manufacturers have had in ramping up production of tests.
    While current test availability is sufficient to meet the increased 
testing demands due to the ETS, OSHA is also confident that the RADx-
TECH/ATP initiatives will continue to spur testing capacity and growth. 
The RADx-TECH/ATP initiatives have focused on moving test makers' 
products through the late stage pipeline and securing FDA authorization 
for entry into the market. So far, there have been 27 such 
authorizations. As of September 2021, there were 824 eligible late-
stage scale up proposals from various test makers up for review for 
NIH/BARDA funding. Furthermore, 517 of these submissions are for the 
authorization and production of multiple types of COVID-19 tests 
including one or more of the following: Blood, sputum, nasal swab, oral 
swab, fecal, saliva, or other types. OSHA considers this to be further 
support for its determination that testing capacity will continue to 
grow and that increased COVID-19 testing supplies are on the horizon 
(NIBIB, September 28, 2021).
    Based on data from the Johns Hopkins Coronavirus Resource Center, 
which examined publicly-available data from multiple sources, 
approximately 12.4 million tests were conducted during the week of 
August 26-September 2, 2021. As noted earlier, in the economic analysis 
of this ETS, OSHA projects testing rates to increase by approximately 
7.2 million tests per week starting 60 days after publication of the 
ETS. As described above, many employers are currently testing their 
workforce. This 7.2 million is almost certainly an overestimate because 
it does not exclude employees who are already required to be tested by 
their employers and would continue to be tested at the same frequency 
after the ETS. The data reviewed by OSHA on the RADx-TECH/ATP Dashboard 
shows that the manufacturers supported by the initiative are producing 
approximately 30 million tests per week, and capacity continues to 
grow. As explained above, it is expected that roughly 50 million at-
home COVID-19 tests will be available each week by December 2021. OSHA 
therefore finds that there are (and will continue to be) sufficient 
COVID-19 tests available to meet the anticipated demand related to 
compliance with paragraph (g) by the 60-day delayed compliance date.
d. Availability of COVID-19 Test Supplies
    OSHA has also analyzed the availability of COVID-19 test supplies 
for use by COVID-19 test kit manufacturers, diagnostic laboratories, 
and determined that there are sufficient supplies to allow compliance 
with the ETS testing option. The COVID-19 pandemic and recent Delta 
Variant surge have caused some disruptions in the availability of 
testing supplies such as swabs, viral transport medium, RNA extraction 
kits, serology consumables, diagnostic reagents, plastic consumables, 
and diagnostic instruments. The COVID-19 testing supply market is 
driven by the need to rapidly screen large segments of the population 
and deliver test results. The data presented throughout this assessment 
has shown demand for laboratory COVID-19 tests is rising across the 
country.
    Testing for COVID-19 involves many different components that are 
manufactured, transported, and used independently (e.g., bulk solvents, 
extracting reagents, packaging) or semi-independently (e.g., test 
kits). Most of the supplies used in COVID-19 testing are disposable, 
requiring a constant sustained capacity for new supplies. Some 
distribution channels move supplies directly to medical and laboratory 
end-users and others move supplies through distributors. In either 
case, the combination of increased testing demand and the established 
supply chains indicate that testing kits will be available in 
sufficient quantities throughout the country, including in rural areas 
where large employers may be located.
    There have been substantial investments from federal and state 
programs and private industry to stimulate the production and 
distribution of testing supplies to bolster testing capacity across the 
country. Many products, such as swabs and reagents for RNA extraction 
kits, exhibited rising demand and, at some point during the pandemic, 
were subject to shortages that threatened continued testing capacity. 
For example, there was only one domestic manufacturer of medical grade 
flocked swabs, Puritan Medical Products Company of Guilford, Maine, and 
the company's pre-pandemic capacity was insufficient to meet demand of 
increased testing in the early period of the COVID-19 pandemic (Puritan 
Products, April 20, 2020). On July 29, 2020, the Department of Defense 
(DOD), in coordination with the Department of Health and Human 
Services, awarded $51.15 million to Puritan to expand industrial 
production capacity of flock tip testing swabs (DOD, July 31, 2020). On 
March 26, 2021, Puritan was awarded another $146.77 million to increase 
the company's total production capacity to 250 million foam tip swabs 
per month at its Tennessee facility by February 2022 (DOD, March 29, 
2021).
    Other private sector companies were mobilized to change the 
products they manufactured to accelerate production of COVID-19 test 
components, such as swabs, reagents, and solvents for RNA extraction 
kits. For example, Microbrush, a U.S.-based manufacturer of sterile 
applicators for the dental industry, began production of a 
nasopharyngeal test swab to meet the growing demand for COVID-19 
testing requirements in July 2020. The Microbrush test swabs are 
sterilized and individually packaged in a medical-


grade pouch intended for nasopharyngeal sample collection such as in 
dental procedures and also COVID-19 testing (Microbrush, July 1, 2020).
    RNA extraction kits are used by the majority of NAAT protocols. 
These kits are sets of consumable plastic laboratory materials (small 
centrifuge tubes, filters, and collection vials) and chemical reagents 
(solutions for breaking the virus apart and purification) assembled by 
a manufacturer. Each kit has enough materials to process several dozen 
samples. The use of RNA extraction kits is not exclusive to COVID-19 
testing, meaning that a market existed pre-COVID-19, and manufacturers 
were able to adapt to fluctuations in demand spurred by the pandemic.
    There are multiple companies with facilities in the United States 
that produce RNA extraction kits for the domestic market that have been 
awarded federal grants to increase the supply of COVID-19 test kits and 
reagent supplies. For example, in December 2020, the DOD and HHS 
identified several key reagents with the potential for supply chain 
bottlenecks and awarded a $4.8 million Indefinite Delivery/Indefinite 
Quantity contract to Anatrace Products, LLC to support increased 
production of key reagents for sample processing; Polyadenylic Acid 
(Poly A), Guanidinium Thiocyanate (GTC), and Proteinase K (Pro K) to 
process samples (DOD, December 21, 2020). Additionally, QIAGEN (based 
in Germany with U.S. manufacturing in Germantown, Maryland) produces 
extraction kits for authorized COVID-19 tests and has responded to the 
pandemic by scaling their production to around the clock production to 
strengthen testing kit capacity (Qiagen, October 2, 2021). On August 
23, 2021, DOD, on behalf of and in coordination with HHS, awarded a 
$600,000 contract to QIAGEN to expand manufacturing capacity of 
enzymatic reagents and reagent kits used in COVID-19 molecular 
diagnostic tests, thereby allowing QIAGEN to increase its monthly 
production of reagent kits by 7,000 and enzymes by 5,100 milligrams by 
the end of February 2022 to support domestic laboratory testing for 
COVID-19 (DOD, August 23, 2021).
    Additionally, manufacturers of raw materials and solvents for 
COVID-19 test kits have implemented strategies to strengthen their 
portions of the COVID-19 test supply chain. Millipore Sigma, a large 
producer of solvents and raw materials for tests, has created a global 
task force to actively evaluate the overall supply chain of products 
and key raw material suppliers to mitigate any potential disruption of 
COVID-19 testing capacity (Millipore Sigma, October 2021). In light of 
the foregoing, OSHA believes that there is sufficient--and increasing--
availability of COVID-19 testing supplies to enable compliance with the 
ETS testing option.
e. Sufficiency of Laboratory Capacity
    As noted above, a wide range of tests are acceptable under the ETS, 
including those that can be observed by employers without laboratory 
processing. Moreover, there has been rapid growth in the availability 
of OTC tests that do not require laboratory processing. Authorized OTC 
tests self-administered by employees and proctored by the employer do 
not require a CLIA certificate of waiver.
    The Association of Public Health Laboratories (APHL) has conducted 
weekly surveys of its membership to monitor their current and projected 
capability and capacity to test for COVID-19. Data from this survey is 
used to inform HHS, FEMA, CDC, and other federal partners to support 
public health laboratory supply and reagent needs. OSHA reviewed the 
weekly COVID-19 survey results through the APHL COVID-19 Lab Testing 
Capacity and Capability Data Dashboard. The data comes from voluntary 
participation in the weekly surveys collected from approximately 100 
state, local and territorial public health laboratories (PHLs) and 
reported to the CDC. The APHL weekly survey data supports OSHA's 
feasibility determination and demonstrates that COVID-19 testing demand 
will be met. For example, from August 15, 2021 to September 12, 2021, 
the APHL weekly survey data found that 96-100% of PHLs are meeting 
their current testing demand since the Delta Variant surge began (APHL, 
September 27, 2021).
    Laboratory capacity for processing and confirmation of at-home 
COVID-19 rapid tests provided by manufacturer retailers such as Walmart 
has also increased. Laboratory and diagnostic service providers have 
implemented parallel strategies to strengthen laboratory capacity for 
confirmation of at-home COVID-19 rapid tests available on the market 
for employers and employees to utilize. For example, Quest Diagnostics, 
which is the laboratory processing the samples and delivering results 
to those tested at Walmart's drive-through and curbside testing sites, 
has scaled up laboratory testing capacity and rapid antigen test 
inventory should demand increase (Walmart, July 9, 2021). Quest 
Diagnostics has added COVID-19 testing platforms in laboratories in 
regions where demand is comparatively high and has implemented an 
online consumer-initiated test service for individuals and small 
businesses to request COVID-19 testing. In August 2021, Quest 
Diagnostics began to offer clinician-guided rapid COVID-19 antigen 
testing to employers through a guided telehealth visit using a self-
administered, nasal swab antigen test that provides results in 15 
minutes that is then shipped to a Quest Diagnostics lab for 
confirmation (Quest Diagnostics, September 28, 2021).
    Based on the evidence reviewed, OSHA has determined that there is 
adequate laboratory capacity to enable compliance with the ETS testing 
option.
f. Access to Testing in Underserved Communities
    Individuals in underserved communities (including Black, Latino, 
and Indigenous and Native American persons, Asian Americans and Pacific 
Islanders and other persons of color; members of religious minorities; 
lesbian, gay, bisexual, transgender, and queer persons; persons with 
disabilities; persons who live in rural areas; and persons otherwise 
adversely affected by persistent poverty or inequality) are 
disproportionately burdened by the COVID-19 pandemic as many 
individuals in these communities are essential workers who cannot work 
from home, increasing their risk of being exposed to the virus. Access 
to COVID-19 testing in these communities has been identified as 
contributing factor to COVID-19 related health disparities in these 
communities. For example, the NSC June 2021 survey found that the most 
common barrier to testing for rural employers and workers is access to 
vaccination and testing sites (NSC, September 2021).
    Several federal efforts have recently been implemented to 
strengthen testing capabilities in underserved communities. The NIH has 
invested heavily to improve COVID-19 testing in underserved communities 
throughout the COVID-19 pandemic. On September 30, 2020, the NIH 
received nearly $234 million to improve COVID-19 testing for 
underserved and vulnerable populations that have been 
disproportionately affected by this pandemic and launched the RADx 
Underserved Populations (RADx-UP) program (NIH, September 30, 2020).
    The RADx-UP program has primary components supported by these NIH 
grants to increase availability, accessibility, and acceptance of 
testing among underserved and vulnerable populations. The RADx-UP 
program also provides overarching support and


guidance on administrative operations and logistics, facilitating 
effective use of COVID-19 testing technologies, supporting community 
and health system engagement, and providing overall infrastructure for 
data collection, integration, and sharing from a coordination and data 
collection center (NIH, September 30, 2021). Through the RADx-UP 
program, the NIH has continued to support the needs of underserved 
populations and is currently funding 70 community-based projects across 
the country (NIH, September 30, 2021).
    The CDC has also focused its efforts to improve COVID-19 testing in 
underserved communities throughout the COVID-19 pandemic. For example, 
on September 20, 2021, Maine Health, the largest health care 
organization in Maine and also serving northern New Hampshire, was 
awarded nearly $1 million for COVID-19 testing in higher risk 
communities (Maine Health, September 20, 2021). In March 2021, the CDC 
implemented a plan to invest $2.25 billion over two years to address 
COVID-19 related health disparities and advance health equity among 
populations that are at high-risk and underserved, including racial and 
ethnic minority groups and people living in rural areas. Since that 
time, the CDC has awarded grants to public health departments to 
improve testing capabilities; improve data collection and reporting; 
and build, leverage, and expand infrastructure support for testing 
(CDC, March 17, 2021). On September 30, 2021, the CDC awarded an $8.1 
million grant to the Arizona Center for Rural Health (ACRH) to address 
COVID-19 disparities across Arizona by improving the delivery of COVID-
19 testing to rural and underserved communities (ASU CRH, September 30, 
2021). A number of other federal and state government agencies have 
been expanding support for COVID-19 testing in underserved communities 
as well. On June 11, 2021, HHS through the Health Resources and 
Services Administration (HRSA) provided $424.7 million in American 
Rescue Plan funding to over 4,200 Rural Health Clinics (RHCs) for 
COVID-19 testing (HHS, June 11, 2021).
    Private industry has also mobilized considerably to increase access 
and testing capacity in rural and other underserved communities. The 
NSC June 2021 survey found that a common barrier to employers and 
employees in rural and other underserved communities is transportation 
and access to vaccination and testing sites (NSC, September 2021). In 
its final report, the NSC recommended employers in these communities 
host on-site vaccinations to increase worker access. Applications for 
mobile vaccination are available on most local and state health 
department websites (NSC, September 2021; ASU WEF, September 2021).
    CVS has collaborated with several organizations, including the 
National Medical Association, to increase access to testing in 
underserved communities and has developed mobile solutions that allow 
health care professionals to bring testing capabilities to businesses 
in these communities as they re-open (CVS Health, September 2021). 
Walgreens has implemented efforts to increase access in underserved 
communities such as rural and/or lower socioeconomic communities as 
well, with now more than half of Walgreens testing sites currently 
located in areas the CDC has identified as socially vulnerable and 
underserved (Walgreens, October 2021). Because of these investments, 
OSHA concludes that employers and their employees in underserved 
communities, including those in rural areas, will have sufficient 
access to COVID-19 tests and will be able to comply with the ETS's 
testing requirements for employees who are not fully vaccinated.
V. Management of Confidential Medical Records, Including Employee 
COVID-19 Vaccination and Testing Records
    The ETS requires employers to maintain a record of each employee's 
vaccination status. Employers must also maintain a record of each test 
result provided by each employee. These records must be maintained as 
confidential medical records and must not be disclosed except as 
required or authorized by this ETS or other federal law. The records 
are not subject to the retention requirements of 29 CFR 
1910.1020(d)(1)(i) but must be maintained and preserved while the ETS 
is in effect.
    Other OSHA rules have a similar requirement to maintain employee 
medical records, which could include vaccination records. See, e.g., 
Bloodborne Pathogens (29 CFR 1910.1030), Respiratory Protection (29 CFR 
1910.134), Respirable Crystalline Silica (29 CFR 1910.1053), Beryllium 
(29 CFR 1910.1024), Lead (29 CFR 1910.1025), and OSHA's requirements 
for employee access to medical and exposure records (29 CFR 1910.1020). 
OSHA is not aware of any potential technological feasibility issues 
related to recordkeeping.
    The requirement under this ETS to maintain records of employees' 
COVID-19 vaccination status and COVID-19 test results is similar to 
requirements in the aforementioned OSHA standards, and OSHA therefore 
concludes that compliance is feasible. Employers subject to the ETS 
will be able to comply with the provisions in the ETS using 
straightforward recordkeeping systems that are already widely used by 
large employers as part of their usual and customary business 
practices. OSHA concludes that it is feasible for such employers to 
comply with the requirements in the ETS for maintaining records related 
to COVID-19 vaccination status and COVID-19 test results.
VI. Other Provisions
    There are no technological feasibility barriers related to 
compliance with other requirements in the ETS (e.g., face coverings, 
employee notification). As explained above, many of the employer plans 
and best practice documents reviewed by OSHA indicate that employers 
have implemented the measures in these provisions across industry 
sectors. OSHA highlights two of the ETS's other requirements below, 
which are explored in more depth in other sections of this preamble.
     Face Coverings. Paragraph (i) of the ETS requires the 
employer to ensure that all employees who are not fully vaccinated wear 
a face covering when indoors and when occupying a vehicle with another 
person for work purposes, except: (i) When an employee is alone in a 
room with floor to ceiling walls and a closed door; (ii) for a limited 
time while the employee is eating or drinking at the workplace or for 
identification purposes in compliance with safety and security 
requirements; (iii) when employees are wearing respirators or face 
masks; or (iv) where the employer can show that the use of face 
coverings is infeasible or creates a greater hazard. The definition of 
face covering allows various different types of masks, including clear 
face coverings or cloth face coverings with a clear plastic panel which 
may be used to facilitate communication with people who are deaf or 
hard-of-hearing or others who need to see a speaker's mouth or facial 
expressions to understand speech or sign language respectively. The 
types of face coverings permitted under this ETS are widely used and 
readily available. The results of the ASU WEF June 2021 survey found 
that 30% of employers required face coverings for unvaccinated 
employees, which demonstrates that this provision of the ETS is 
currently being implemented by a substantial number of employers and is 
``capable of being done.'' (ASU WEF, September 2021). OSHA identifies 
no technological


feasibility issues with this provision of the ETS.
     Notification. Paragraph (h) of the ETS contains COVID-19 
notification requirements for both the employer and the employee. Under 
this provision, the employer must require each employee to promptly 
notify the employer if they receive a positive COVID-19 test or are 
diagnosed with COVID-19 by a licensed healthcare provider and must 
immediately remove any employee from the workplace who receives a 
positive COVID-19 test or is diagnosed with COVID-19 by a licensed 
healthcare provider. OSHA identifies no technological feasibility 
issues in connection with the ETS's notification requirements. It is 
the employer's responsibility to ensure that appropriate instructions 
and procedures are in place so that designated representatives of the 
employer (e.g., managers, supervisors) and employees conform to the 
rule's requirements.
VII. Conclusion
    OSHA has determined that complying with this ETS is technologically 
feasible for typical firms covered by this standard, at least most of 
the time (see Public Citizen v. OSHA, 557 F.3d 165 (3d Cir. 2009); Lead 
I, 647 F.2d at 1272; Lead II, 939 F.2d at 990). OSHA reviewed extensive 
evidence across industries and did not identify any industry-specific 
compliance barriers. Evidence in the record that shows that the written 
workplace COVID-19 vaccination policy requiring each employee to be 
fully vaccinated against COVID-19 unless they establish and implement a 
written policy that permits an employee to choose to be tested for 
COVID-19 at least every seven days and wear a face covering is 
feasible. In fact, such policies have already been implemented by 
hundreds of large companies across industry sectors. OSHA has also 
determined that there are sufficient COVID-19 tests available and 
adequate laboratory capacity to meet the anticipated increased testing 
demand related to compliance with the ETS testing option.
    Additionally, the ETS's requirements to determine employee 
vaccination status, support employee vaccination by providing time off 
for vaccination and time off for recovery, and maintain records of 
employee COVID-19 vaccination status and COVID-19 test results are also 
technologically feasible. As discussed above, that many employers and 
organizations have already implemented such requirements demonstrates 
that they are ``capable of being done.'' Moreover, the recordkeeping 
requirements in this ETS largely mirror the requirements for the 
collection and maintenance of similar employee medical records in 
OSHA's Bloodborne Pathogens standard (29 CFR 1910.1030) and the 
Respiratory Protection standard (29 CFR 1910.134). The ETS provides a 
flexible compliance option for employers to tailor their procedures and 
practices to the needs of their workplace. OSHA finds that employers in 
typical firms in all industry sectors can comply with the requirements 
of the ETS, and compliance with the ETS is therefore technologically 
feasible.

B. Economic Analysis

I. Introduction
    This section presents OSHA's estimates of the costs and impacts, 
anticipated to result from the COVID-19 Vaccination and Testing ETS, 29 
CFR 1910.501. The purpose of this ETS is to address the grave danger of 
COVID-19 in the workplace by promoting vaccination, while allowing an 
alternative for face covering and testing requirements, and also to 
remove COVID-19 positive workers from the workplace regardless of 
vaccination status. The estimated costs are based on employers 
achieving full compliance with the requirements of the ETS. They do not 
include prior costs associated with firms whose current practices are 
already in compliance with the ETS requirements. The purpose of this 
analysis is to:
     Identify the entities/establishments and industries 
affected by the ETS;
     Estimate and evaluate the costs and economic impacts that 
regulated entities/establishments will incur to achieve compliance with 
the ETS; and
     Evaluate the economic feasibility of the rule for affected 
industries.
    In this analysis, OSHA is fulfilling the requirement under the OSH 
Act to show the economic feasibility of this ETS. This analysis is 
different from the cost portion of a regulatory impact analysis 
prepared in accordance with Executive Order 12866 in that the agency is 
focused only on costs to employers when evaluating economic 
feasibility. In a regulatory impact analysis, the costs to all parties 
(e.g., employers, employees, and governments) are included. While this 
is not the case for an economic feasibility analysis, it does not 
necessarily mean that the ETS imposes no costs or burdens on parties 
other than employers. For example, the rule imposes certain costs on 
employees who choose not to become vaccinated (e.g., for face coverings 
and testing. While these costs are not relevant for the purpose of 
establishing economic feasibility, these costs would be attributable to 
the ETS in a regulatory impact analysis. In addition, these costs are 
not mandatory because any employee who does not wish to pay them may 
choose to become vaccinated or leave employment (see discussion below 
on turnover), after which the costs would not be incurred. Some 
employees may also be entitled to a reasonable accommodation that may 
avoid additional cost (e.g., telework).
    ``[T]he Supreme Court has conclusively ruled that economic 
feasibility [under the OSH Act] does not involve a cost-benefit 
analysis.'' Pub. Citizen Health Research Grp. v. U.S. Dept. of Labor, 
557 F.3d 165, 177 (3d Cir. 2009); see also Asbestos Info. Ass'n, 727 
F.2d at 424 n.18 (noting that formal cost benefit is not required for 
an ETS, and indeed may be impossible in an emergency). The OSH Act 
``place[s] the `benefit' of worker health above all other 
considerations save those making attainment of this `benefit' 
unachievable.'' Cotton Dust, 452 U.S. at 509. Therefore, ``[a]ny 
standard based on a balancing of costs and benefits by the Secretary 
that strikes a different balance than that struck by Congress would be 
inconsistent with the command set forth in'' the statute. Id. While 
this case law arose with respect to health standards issued under 
section 6(b)(5) of the Act, which specifically require feasibility, 
OSHA finds the same concerns applicable to emergency temporary 
standards issued under section 6(c) of the Act. An ETS ``serve[s] as a 
proposed rule'' for a section 6(b)(5) standard, and therefore the same 
limits on any requirement for cost-benefit analysis should apply. 
Indeed, OSHA has also rejected the use of formal cost benefit analysis 
for safety standards, which are not governed by section 6(b)(5). See 58 
FR 16,612, 16,622-23 (Mar. 30, 1993) (``in OSHA's judgment, its 
statutory mandate to achieve safe and healthful workplaces for the 
nation's employees limits the role monetization of benefits and 
analysis of extra-


workplace effects can play in setting safety standards.'').\22\ A 
standard must be economically feasible in order to be ``reasonably 
necessary and appropriate'' under section 3(8) and, by inference, 
``necessary'' under section 6(c)(1)(B) of the OSH Act. Cf. Am. Textile 
Mfrs. Inst., Inc. v. Donovan, 452 U.S. 490, 513 n.31 (1981) (noting 
``any standard that was not economically . . . feasible would a 
fortiori not be `reasonably necessary or appropriate' '' as required by 
the OSH Act's definition of ``occupational safety and health standard'' 
in section 3(8)); see also Florida Peach Growers, 489 F.2d at 130 
(recognizing that the promulgation of any standard, including an ETS, 
must account for its economic effect). A standard is economically 
feasible when industries can absorb or pass on the costs of compliance 
without threatening industry's long-term profitability or competitive 
structure, Cotton Dust, 452 U.S. at 530 n.55, or ``threaten[ing] 
massive dislocation to, or imperil[ing] the existence of, the 
industry.'' United Steelworkers of Am. v. Marshall, 647 F.2d 1189, 1272 
(D.C. Cir. 1981) (Lead I). Given that section 6(c) is aimed at enabling 
OSHA to protect workers in emergency situations, the agency is not 
required to make the showing with the same rigor as in ordinary section 
6(b) rulemaking. Asbestos Info. Ass'n/N. Am. v. OSHA, 727 F.2d 415, 424 
n.18 (5th Cir. 1984). In Asbestos Information Association, the Fifth 
Circuit concluded that the costs of compliance were not unreasonable to 
address a grave danger where the costs of the ETS did not exceed 7.2% 
of revenues in any affected industry. Id. at 424.
---------------------------------------------------------------------------

    \22\ To support its Asbestos ETS, OSHA conducted an economic 
feasibility analysis on these terms. 48 FR 51086, 51136-38 (Nov. 4, 
1983). In upholding that analysis, the Fifth Circuit said that OSHA 
was required to show that the balance of costs to benefits was not 
unreasonable. Asbestos Info. Ass'n, 727 F.2d at 423. As explained 
above, OSHA does not believe that is a correct statement of the 
economic feasibility test. However, even under that approach this 
ETS easily passes muster.
---------------------------------------------------------------------------

    The scope of judicial review of OSHA's determinations regarding 
feasibility (both technological and economic) ``is narrowly 
circumscribed.'' N. Am.'s Bldg. Trades Unions v. OSHA, 878 F.3d 271, 
296 (D.C. Cir. 2017) (Silica). ``OSHA is not required to prove economic 
feasibility with certainty, but is required to use the best available 
evidence and to support its conclusions with substantial evidence.'' 
Amer. Iron & Steel Inst. v. OSHA, 939 F.2d 975, 980-81 (D.C. Cir. 1991) 
(Lead II); 29 U.S.C. 655(b)(5), (f). ``Courts, [moreover], `cannot 
expect hard and precise estimates of costs.' '' Silica, 878 F.3d at 296 
(quoting Lead II, 939 F.2d at 1006). Rather, OSHA's estimates must 
represent ``a reasonable assessment of the likely range of costs of its 
standard, and the likely effects of those costs on the industry.'' Lead 
I, 647 F.2d at 1266. The ``mere `possibility of drawing two 
inconsistent conclusions from the evidence,' or deriving two divergent 
cost models from the data `does not prevent [the] agency's finding from 
being supported by substantial evidence.' '' Silica, 878 F.3d at 296 
(quoting Cotton Dust, 452 U.S. at 523).
    Executive Orders 12866 and 13563 direct agencies to assess the 
costs and benefits of the intended regulation and, if regulation is 
necessary, to select regulatory approaches that maximize net benefits 
(including potential economic, environmental, and public health and 
safety effects; distributive impacts; and equity). Executive Order 
13563 emphasized the importance of quantifying both costs and benefits, 
of reducing costs, of harmonizing rules, and of promoting flexibility. 
Because of the continued impact of the pandemic on occupational safety 
and health, OSHA has prepared this ETS and the accompanying economic 
analysis on an extremely condensed timeline. Thus, in light of the 
Secretary's conclusion that the COVID-19 pandemic constitutes an 
emergency situation, the Secretary has notified OIRA that it is 
necessary for OSHA to promulgate this regulation more quickly than 
normal review procedures allow, pursuant to E.O. 12866 Sec. 6 
(a)(3)(D). OIRA has waived compliance with Sec. 6(a)(3)(B) and (C) for 
this economically significant rule.
II. COVID-19 ETS Industry Profile
a. Introduction
    In this section, OSHA provides estimates of the number of affected 
entities, establishments, and employees for the industries that have 
settings covered by this ETS. The term ``entity'' describes a legal 
for-profit business, a non-profit organization, or a local governmental 
unit, whereas the term ``establishment'' describes a particular 
physical site of economic activity. Some entities own and operate more 
than one establishment.
    Throughout this analysis, where estimates were derived from 
available data those sources have been noted in the text. Estimates 
without sources noted in the text are based on agency expertise.
b. Scope of the COVID-19 ETS
    This ETS applies to all employers with a total of 100 or more 
employees at any time this ETS is in effect. However, the requirements 
of this ETS do not apply to: (1) Workplaces covered under the Safer 
Federal Workforce Task Force COVID-19 Workplace Safety: Guidance for 
Federal Contractors and Subcontractors (Contractor Guidance); or (2) 
settings where any employee provides healthcare services or healthcare 
support services when subject to the requirements of 29 CFR 1910.502 
(i.e., the Healthcare ETS). Furthermore, the requirements of this ETS 
do not apply to the employees of covered employers: (1) Who do not 
report to a workplace where other individuals, such as coworkers or 
customers, are present; or (2) while working from home; or (3) who work 
exclusively outdoors. Based on this scope, employers in nearly every 
sector are expected to be covered by this ETS.
    OSHA's assumptions may result in an overestimate of the number of 
employees affected by the ETS. First, OSHA is not estimating the number 
and type of workplaces covered by the Safer Federal Workforce Task 
Force COVID-19 Workplace Safety: Guidance for Federal Contractors and 
Subcontractors or removing them from the profile of employers affected 
by this ETS. OSHA assumes for the purpose of this analysis that 
employers covered under the Contractor Guidance will also have 
contracts to perform work in workplaces where they are not covered 
under that Guidance (i.e., where the employer contracts with an entity 
other than the federal government), and so those employers are included 
in the scope here.
    Second, OSHA estimates that all employers in all private sector 
industries are affected by this ETS to some extent. Although this ETS 
imposes no compliance burden on employers whose employees work remotely 
100 percent of the time, in OSHA's analysis, no employers with 100 or 
more employees have all of their employees working remotely 100 percent 
of the time (i.e., at least some employees in each affected firm do not 
work remotely). Moreover, OSHA's analysis does not take into account 
that some employees may engage in part-time telework (i.e., it assumes 
that employees either work remotely full-time or do not work remotely 
at all). Finally, OSHA's analysis does not fully take into account the 
exemption for employees who do not report to a workplace where other 
individuals are present, meaning that this analysis may overestimate 
the number of employees affected by the rule.
    As stated, the requirements of this ETS do not apply to the 
employees of covered employers who work


exclusively outdoors. To determine the percentage of employees in 
occupations for which the exception is relevant, the agency uses data 
from the BLS's 2020 Occupational Requirements Survey (ORS) (BLS, 2020). 
This survey looks at various aspects of job requirements. In 
particular, the survey lists occupations where workers are outdoors 
``constantly,'' which OSHA interprets as being nearly continuously 
outdoors. Because the majority of workers who work outdoors 
``constantly'' likely work indoors at least some of the time, the 
agency judges that no more than 10 percent of the workers who are 
primarily outdoors are actually there exclusively. See Table IV.B.1 for 
the occupations, the ORS percentages, and final percentages for workers 
OSHA estimates are exempt from the scope of this ETS based on the 
outdoor work exemption.
[GRAPHIC] [TIFF OMITTED] TR05NO21.000

    OSHA's estimate of employees who work exclusively outdoors does not 
account for employers who only need to make slight adjustments to their 
current work practices to ensure that their employees qualify for the 
outdoor exemption, such as by holding tool box talks outdoors instead 
of in a traditional indoor location. This may result in more employees 
falling within the exemption than estimated by OSHA; therefore, OSHA's 
cost analysis likely overestimates costs.
    The requirements of the ETS also do not apply to settings where any 
employee provides healthcare services or healthcare support services 
when subject to the requirements of 29 CFR 1910.502 (the Healthcare 
ETS). The Healthcare ETS is a temporary standard that may not remain in 
effect for the entire period that 29 CFR 1910.501 remains in effect. 
This means that some employers or employees covered by the Healthcare 
ETS, those in firms that have 100 or more employees, may ultimately be 
covered by 29 CFR 1910.501 (because the exception in 29 CFR 1910.501 is 
limited to when employers are subject to the requirements of the 
Healthcare ETS). This potentially impacts two types of costs: Employer-
based costs (e.g., employer policy on vaccination) and employee-based 
(periodic) costs (e.g., recordkeeping).
    Employer-Based Costs: For the purpose of the economic analysis 
only, OSHA treats the Healthcare ETS as though it will no longer be in 
effect after December, 2021, because at that point the Healthcare ETS 
will have been in effect for the six months that OSHA had calculated 
costs for that ETS. Therefore, OSHA estimates that some employers 
including those with 100 or more employees subject to the 29 CFR 
1910.502 exemption, will need to take employer-based costs because all 
these employers will ultimately be subject to 29 CFR 1910.501 under 
this assumption.
    Employee-Based Costs: OSHA's estimates incorporate two assumptions 
for the purposes of this analysis only. First, for the purposes of 
assumptions for this analysis only, Sec.  1910.501 will remain in 
effect for 6 months. Second, many employers and employees currently 
covered only by the Healthcare ETS will be subject to the requirements 
of 29 CFR 1910.501 for approximately 4 months (4 months of the 6 month 
estimated lifespan of 29 CFR 1910.501). OSHA's estimate of those 
employees exempted by the Healthcare ETS was based on the Industry 
Profile of employees in firms with 100 employees or more covered by the 
Healthcare ETS, as estimated in Table VI.B.3 in the economic analysis 
for that rulemaking (see 86 FR 32488).
    OSHA notes that some employees currently covered by the Healthcare 
ETS might also be currently covered by 29 CFR 1910.501 (albeit at 
different times or in different locations) because the Healthcare ETS 
is settings-based. For example, a pharmacist would normally not need to 
comply with the requirements of Sec.  1910.502 when just filling 
prescriptions in a retail pharmacy store (see 29 CFR 
1910.502(a)(2)(ii)), but would need to comply when administering 
vaccinations within an embedded clinic inside that retail pharmacy. 
Thus, there are a number of variables that could impact the extent to 
which the pharmacist's employer might


incur any costs. However, even to the extent that such costs might 
occur (e.g., recordkeeping for testing if the pharmacist works for an 
employer covered by 29 CFR 1910.501 and is unvaccinated), OSHA judges 
that they would be de minimis for several reasons. First, this pool of 
workers is likely to be very small, especially when compared to the 
population of workers covered by the Healthcare ETS. Second, most 
employees subject to both standards will have been fully vaccinated 
before OSHA takes costs for these employees under 29 CFR 1910.501 by 
operation of the CMS rule mandating vaccination or as a result of the 
voluntary vaccination incentives promoted by OSHA's Healthcare ETS 
(therefore negating most of the costs associated with vaccination and 
testing under 29 CFR 1910.501). Third, any underestimate of periodic 
costs will only apply during the first two months after 29 CFR 1910.501 
goes into effect and the standard has a delayed compliance date of 30 
days after the effective date for most provisions, except for testing, 
which has a delayed compliance date of 60 days. This will further 
lessen the periodic costs associated with any potential underestimate.
    In all respects (other than the \4/6\ share of employee-based 
costs), OSHA is taking the same approach in the Industry Profile and 
Cost Estimates for employers and employees currently covered by the 
Healthcare ETS as it does for all other industries. These employers and 
employees are fully integrated into Table IV.B.5, below, which contains 
a summary of covered entities and employees. Moreover, the same 
assumptions on outdoor work and other scope exemptions that OSHA 
explains earlier holds for these employers and employees. In addition, 
OSHA makes the same downward adjustment in telework for these employers 
and employees in accordance with the methodology it sets out below. 
Thus, the Healthcare ETS profile used in this ETS to account for 
employees exempted by the Healthcare ETS into the Profile in the event 
the Healthcare ETS expires (i.e., in Table IV.B.5, below) is an updated 
version of Table VI.B.3 in the Healthcare ETS (see 86 FR 32488).\23\ 
OSHA notes that some firms may decide to proactively comply with 
certain 29 CFR 1910.501 requirements (such as mandating vaccination for 
all employees that were removed from the Industry Profile) before the 
end date of the Healthcare ETS based on the conclusion that 29 CFR 
1910.501 will ultimately apply in full to them. Since these costs still 
occur due to 29 CFR 1910.501, OSHA is appropriately including them in 
this cost analysis.
---------------------------------------------------------------------------

    \23\ The CMS rule published elsewhere in this issue of the 
Federal Register mandates vaccination for employees in facilities 
that receive Medicare or Medicaid. OSHA is ignoring this for the 
purpose of its cost analysis and taking costs into account as if the 
CMS rule were not promulgated. This creates a substantial 
overestimate.
---------------------------------------------------------------------------

    There are 9.9 million employees who will newly be covered by 29 CFR 
1910.501 starting in December whose employers will incur an additional 
$318 million in costs. These costs are integrated into the agency's 
main cost analysis, which is described later in this economic analysis.
    Only some state- and local-government entities are included in this 
analysis. State- and local-government entities are specifically 
excluded from coverage under the OSH Act (29 U.S.C. 652(5)). Workers 
employed by these entities only have OSH Act protections if they work 
in states that have an OSHA-approved State Plan. (29 U.S.C. 667). 
Consequently, this analysis excludes public entities in states that do 
not have OSHA-approved State Plans. Table IV.B.2 presents the states 
that have OSHA-approved State Plans and their public entities are 
included in the analysis.
[GRAPHIC] [TIFF OMITTED] TR05NO21.001

    OSHA notes, finally, that the percentage of employers mandating 
vaccination, and hence the employee vaccination rate, would likely rise 
to some degree absent this ETS due to other federal actions, such as 
the vaccination mandate for federal contractors, the CMS rule published 
elsewhere in this issue of the Federal Register, and as a result of 
vaccination mandates that have been adopted at state and local levels. 
This analysis does not account for increases in vaccination that would 
occur absent the standard, resulting in a likely overestimate of the 
costs.
c. Teleworking
Dingel-Neiman Approach for Estimating Who Can Work Remotely
    OSHA uses the estimates in a paper by J.I. Dingel and B. Neiman, 
``How Many Jobs Can be Done at Home?,'' published in July 2020, as a 
starting point to determine the percentage of employees, by occupation, 
who are not expected to work remotely (i.e., the percentage of workers 
for whom employers have employee-based costs under this ETS) (Dingel 
and Neiman, July 2020).
    In Dingel and Neiman's paper, the authors estimate the number of 
jobs in the U.S. economy that workers can feasibly perform remotely. 
The authors use two different surveys from the


Occupational Information Network (O*Net) \24\ to evaluate which 
occupations can be performed remotely and combine the O*Net estimates 
with the Bureau of Labor Statistics' (BLS) Occupational Employment and 
Wage Statistics (OEWS) data on employment by occupation to estimate the 
total number of workers nationally who can work remotely.
---------------------------------------------------------------------------

    \24\ 24 The O*Net Program is a major source of occupational 
information for the U.S. The O*NET database surveys ask both 
specific occupational experts and workers in those occupations 
questions covering multiple aspects of almost 1,000 occupations 
covering the entire U.S. economy. See https://www.onetonline.org/ 
for more information. The occupation definitions in the O*NET data 
are Standard Occupation Codes--the same definitions that are used in 
the BLS OEWS data. Dingel and Neiman use the responses to two 
surveys included in release 24.2 of the database administered by 
O*NET, the Worker Context Questionnaire and the Generalized Work 
Activities Questionnaire. The occupation with the median number of 
respondents had 26 respondents for each work context question and 25 
respondents for each generalized work activities question per 
detailed-level SOC occupation code.
    In the O*Net Questionnaires, survey respondents responded to 
statements about the nature and requirements of the daily tasks 
associated with their job on a 1-5 ordinal scale, where 5 represents 
the strongest agreement and 1 represents the strongest disagreement 
(see Table IV.B.3). The O*Net data contain the average response to 
each question for each occupation code. For instance, for occupation 
``Chief Executives'' (SOC 11-1011), the average response to the 
prompt ``Performing General Physical Activities is very important'' 
was 1.39, indicating that performing general physical activity is 
not, on average, critical to the work of chief executives. The 
average responses by occupation for other prompts in the relevant 
surveys utilized by Dingel and Neiman are contained in those 
surveys.
---------------------------------------------------------------------------

    To evaluate the survey responses, Dingel and Neiman first 
determined the occupations for which the average response to a given 
prompt met a preset threshold. Table IV.B.3 presents the Dingel and 
Neiman response threshold for each survey question as well as the 
percent of occupations that meet each respective predetermined 
threshold. For example, in 10.8 percent of occupations, the average 
response to the ``Performing general physical activities'' (4.A.3.a.1) 
question met the threshold, falling in the range of 4 to 5.
    Dingel and Neiman determined that employees in a given occupation 
can telework full time if they did not meet the predetermined threshold 
for any of the questions highlighted in grey and denoted with a ``Yes'' 
in the column that reports whether that activity is used in determining 
whether a job can be done remotely in Table IV.B.3.

Adjusting Dingel and Neiman To Reflect Current Conditions
    While many employees can and are working remotely, many have 
returned to their places of employment. This conclusion is borne out by 
BLS's Current Population Survey (CPS) (BLS, 2021c). To address the 
tendency toward employees returning to work on site and more accurately 
reflect current remote work conditions, OSHA made two adjustments to 
Dingel and Neiman's estimates. In the COVID-19 Healthcare ETS, OSHA 
also used Dingel and Neiman's paper to estimate the number of workers 
who teleworked in response to the pandemic and the ETS under the 
assumption that anyone who could work remotely would do so in response 
to the pandemic and the Healthcare ETS. Dingel and Neiman's estimates 
are therefore framed as the upper-bound of potential teleworking.
    The adjustments OSHA made reflect changing circumstances. First, 
based on agency expertise, OSHA changed the status of certain 
occupations in its occupational list from working remotely to not 
working remotely. For example, when Dingel and Neiman published their 
study, many schools were operating virtually so the Dingel and Neiman 
finding that teachers were able to work remotely lined up with the 
situation where teachers were working remotely. At this point in the 
pandemic, on the other hand, in-person learning has mostly recommenced. 
To this end, OSHA changed the status of teachers and other employees in 
the education sector from working remotely to not working remotely in 
this analysis. As another example, many activities that ceased or were 
reduced significantly have now resumed and many locations that were 
closed to the public have reopened (e.g., athletic events, shows, gyms, 
casinos and places of worship), and, since more people have returned to 
the office, there is more need for childcare. Therefore, OSHA also 
changed the status of these employees and others from telework to non-
telework. This has the ultimate effect of increasing costs estimates 
for the rule.
    Appendix A (Table A-1), in the accompanying document in the docket, 
``Vaccination, and Testing ETS: Economic Profile and Cost Chapter 
Appendices'' (OSHA, October 2021b), presents Dingel and Neiman's (July 
2020) unmodified percentages of workers that can work remotely in each 
detailed occupation (based on BLS's Standard Occupation Code 
(SOC)).\25\ Appendix A also presents, in separate columns, percentages 
reflecting the modifications OSHA made in those occupations where OSHA 
changed the results from telework to non-telework for the reasons 
stated, as well as percentages reflecting the modifications made in 
occupations where employees work exclusively outdoors.
---------------------------------------------------------------------------

    \25\ Except for the adjustments to Dingel and Neiman discussed 
above, OSHA used the Dingel and Neiman estimates for telework by 
occupation without change. The agency recognizes that the authors' 
methodology (i.e., the use of 0-1 thresholds) led to a small number 
of results that may appear not to reflect real-world experiences 
within an occupation. However, Dingel and Neiman represents the best 
available evidence for determining the percentage of employees, by 
occupation, who are expected to work remotely. OSHA is aware of no 
other source for this information that contains the level of detail 
necessary to conduct this analysis. Moreover, as explained above, 
OSHA modified the results for individual occupations when it had a 
reasoned basis for doing so. In any event, every NAICS industry is 
comprised of many occupations, so for every occupation where OSHA 
suspects remote work is overestimated in Dingel and Neiman's 
results, there may be another where remote work is underestimated.
---------------------------------------------------------------------------

    According to the OSHA-adjusted Dingel and Neiman estimates, 14 
percent of the jobs in the United States are performed entirely at 
home, with significant variation across cities and industries. It 
should be noted that the Dingel and Neiman analysis does not specify a 
proportion of jobs that can be performed at home part of the time; 
under the analysis, employees are either working remotely full-time or 
are working on site full time.
    The second adjustment OSHA made used monthly COVID-specific 
teleworking data from telework questions added during the pandemic to 
the CPS to estimate the reduction in teleworking since its peak and 
applied those estimates to further adjust downward the number of 
workers currently teleworking (BLS, 2021c). Specifically, the CPS 
questions asked respondents whether they were teleworking due to COVID-
19 (as opposed to teleworking for other reasons) and OSHA estimated the 
difference in teleworking from the peak of COVID-related teleworking in 
all industries, which occurred in May 2020, through August 2021 (see 
Table IV.B.4).\26\ The reduction in teleworking was then applied as the 
change in percentage points to the estimated overall level of employees 
covered by the ETS in each NAICS code estimated based on data from 
Dingel and Neiman (July 2020). OSHA's final teleworking estimates are 
provided in Appendix B in the accompanying document in the docket, 
``Vaccination, and Testing ETS: Economic Profile and Cost Chapter 
Appendices'' (OSHA, October 2021b). Reductions due to employees working 
exclusively outdoors were applied to reduce the percentage of covered 
employees in Appendix B as well.
---------------------------------------------------------------------------

    \26\ The CPS data were available only at the 2-digit NAICS level 
as shown in Table IV.B.4.

Other Teleworking Literature
    A number of companies have announced plans to allow employees to 
work from home at least through the end of 2021--suggesting that the 
levels of remote work will not be returning to pre pandemic levels in 
the near future. Many technology and internet based companies, such as 
Dropbox, Coinbase, VMWare, and Slack, have announced a complete, 
permanent move to fully remote work (Courtney, September 27, 2021). 
Large employers such as Facebook, Amazon, and Siemens plan to maintain 
some physical workspace but now offer their employees who are telework 
eligible the option to work from home at least part of the time on a 
permanent basis (Id.). Google, Ford, Amazon, Apple and other large 
employers are expecting their telework eligible workers to return to 
on-site work (in some capacity) no earlier than January 2022 with Lyft 
anticipating a February 2022 return (Cerullo, August 31, 2021). As a 
final example, a survey of businesses in Massachusetts found that about 
40 percent of teleworkers anticipate they will not be returning to the 
office in January 2022 or earlier (Chesto, June 22, 2021).
    Additional studies provide qualitative support for the conclusion 
that a range of employees will ``predictably'' work from home both 
during the pandemic and beyond. In Bick, Blandin, and Martens's paper, 
``Work from Home Before and After the COVID-19 Outbreak'' the authors 
use the following information to establish the physical location of 
employment (home or workplace) of workers: Data from the Real-Time 
Population Survey (RPS), a


national labor market survey of adults between ages 18-64 that mirrors 
the Current Population Survey (CPS) and collects information used in 
pandemic analysis, such as commuting behavior before and after the 
World Health Organization declared a global pandemic; mobility data on 
commuting; and information from the CPS since May 2020 on `pandemic-
related' telework (Bick et al., February 2021).
    Based on these data, Bick et al., found that there was a sudden 
decline in commuting trips in the U.S. after the initial COVID-19 
outbreak, and that even when these trips subsequently began increasing 
back toward the original number of commuting trips, the overall number 
of trips did not return to normal at the end of 2020 because many 
teleworking employees continued working from home. The authors found 
that the surge in work from home came almost entirely from employees 
working from home every workday in the reference week. The authors also 
suggest that, for some occupations, especially those occupations with 
more educated workers, the change to increased work from home appears 
to be a long-term change; the data showed that, as of December 2020, 
12.5 percent of these workers reported they expect to be working from 
home full-time in the future, and 24.5 percent reported they expect to 
be working from home part-time.
    In ``COVID-19 and Remote Work: An Early Look At U.S. Data,'' 
Brynjolfsson et al., noted that some of the shift to working from home 
seems to be a long-term phenomenon (Brynjolfsson et al., June 2020). 
The authors found, using an online survey, that 35.2 percent of workers 
had switched to working from home. Additionally, 15 percent of workers 
reported they were already working from home before COVID-19. 
Therefore, this study finds that about half of workers are now working 
from home--an even greater percentage than estimated by Dingel and 
Neiman.
    Finally, in ``Why Working from Home Will Stick,'' Barrero et al. 
predict that 22 percent of all full workdays will be performed from 
home after the pandemic ends, compared to 5 percent before (Barrero et 
al., April 2021). The authors highlight five factors contributing 
towards the more permanent shift to telework: Diminished stigma, 
better-than-expected experiences working from home, investments in 
physical and human capital enabling work from home, reluctance to 
return to pre-pandemic activities, and innovation supporting work from 
home.
d. Affected Entities and Employees
    OSHA used data from the U.S. Census' 2017 Statistics of U.S. 
Businesses (SUSB) to identify private sector entities and employees 
affected by this section of the ETS (U.S. Census Bureau, 2019), and 
used the BLS 2017 Quarterly Census of Employment and Wages (QCEW) to 
characterize state and local government entities (BLS, 2017). SUSB 
provides estimates of entities and employees by employer size range, 
which OSHA used to exclude employers with fewer than 100 employees.\27\
---------------------------------------------------------------------------

    \27\ SUSB with revenue data is only collected every 5 years. 
While OSHA could attempt to extrapolate these data to more recent 
years, the results would be imprecise because they would change the 
revenue-employee size distributions. Those distributions are crucial 
for measuring impacts so the agency has opted to use the data as is. 
The total number of employees in OSHA's estimate is fairly close to 
that of SUSB. The 2017 SUSB data includes a total of 128.6 million 
employees, while the more recent 2018 SUSB data includes a total of 
130.9 million.
---------------------------------------------------------------------------

    For rail transportation (NAICS 482), which is not included in SUSB 
or QCEW data, OSHA relied on Federal Railroad Administration and 
Association of American Railroads statistics reported in OSHA's 2020 
final rule, Cranes and Derricks in Construction: Railroad Roadway Work. 
See 85 FR 57109 (September 15, 2020). OSHA used these data sources to 
identify public and private railroad employers with more than 100 
employees. For agricultural NAICS (111 and 112), OSHA relies on the 
National Agricultural Statistics Service, 2017 Census of Agriculture 
(NASS, 2017) to obtain estimates of total entities, employees, and 
revenues. Since these data do not indicate the number of entities with 
more than 100 employees, OSHA assumes it is the same as the average 
proportion as the support activity sectors for crop and animal 
production (NAICS 114 and 115). OSHA similarly specifies teleworking 
conditions for NAICS 111 and 112 using the average result for support 
activities for agriculture (NAICS 114 and 115). For the postal service 
industry, NAICS 491110, which is not included in SUSB, OSHA obtains 
total entity and employment data for private postal services from the 
QCEW. Since these data do not indicate the number of entities with more 
than 100 employees, OSHA assumes it is the same as the average 
proportion as the related industries, couriers and express delivery 
(NAICS 492110), and local delivery (NAICS 492120).
    OSHA used the BLS 2020 Occupational Employment and Wage Statistics 
(OEWS), which provides NAICS-specific estimates of employment and wages 
by occupation, along with the data in Appendix B (discussed earlier), 
to determine the subset of non-teleworking employees affected by the 
ETS.
    Table IV.B.5 summarizes the set of entities covered by the ETS. 
OSHA estimates a total of approximately 263,879 entities and 
approximately 1.9 million establishments incur costs under the ETS.\28\ 
OSHA estimates these entities employ approximately 102.7 million 
employees, and of these, OSHA estimates approximately 84.2 million 
employees are covered by the ETS and are not excluded from coverage by 
working remotely 100 percent of the time or exclusively outside.\29\ 
For the purpose of this analysis, OSHA estimates that all employees 
that OSHA estimated will work remotely will continue to do so for the 
duration of this ETS.\30\
---------------------------------------------------------------------------

    \28\ This includes public entities only in states with an 
approved OSHA State Plan. See Table IV.B.2 above for further 
discussion of state plans.
    \29\ OSHA's estimate of covered employees is based on the 
discussion in the text. For example, as OSHA writes above: OSHA 
assumes for the purpose of its analysis that employers covered under 
the Contractor Guidance will conduct work at least some of the time 
in workplaces not covered under that Guidance and so are fully 
integrated into the scope of the ETS; and the employers and 
employees covered by the Healthcare ETS are also fully integrated 
into the scope of the ETS.
    \30\ Conditions are changing rapidly, and though many firms are 
planning to keep expanded telework to some extent, as the rate of 
vaccinated workers increases, there may be increased movement back 
to the workplace beyond what OSHA has estimated here.

III. Baseline Vaccine Status for Covered Employees
    To estimate the cost of the ETS, OSHA must first estimate the 
baseline vaccination status for the 84.2m covered employees (those who 
work for employers with 100 or more employees and are not otherwise 
excluded from coverage). OSHA recognizes that employees' current 
vaccination status continues to change on a daily basis. When 
specifying baseline vaccination rates, OSHA used the most recently 
available vaccination data from CDC, reflecting current conditions. For 
the remaining set of unvaccinated employees covered by the ETS, after 
accounting for baseline vaccinations, OSHA estimates the number of 
these employees who will be vaccinated and the number who will test 
under the ETS. OSHA's methodology for this analysis is detailed below.
a. Estimate the Current Vaccination Rate for Covered Employees
    To estimate the current vaccinate rate for covered employees, OSHA 
obtained recent vaccination data by age group from the CDC COVID Data 
Tracker (CDC, October 4, 2021a).\31\ For age groups covering 18-74 
years old, these data include the number of people who are fully-
vaccinated as well as the number of people of who have initiated their 
first shot in the past two weeks (relative to the October 4, 2021 
data).\32\ OSHA estimates the vaccination rate for each group (percent 
of total population in the age group who are vaccinated) based on the 
total number of people who are fully-vaccinated and had their first 
shot in the past two weeks, as a fraction of the population in each age 
group, obtained from the BLS Current Population Survey (CPS) (BLS, 
2021d). Then, to estimate the overall average vaccination rate across 
age groups 18-74 years old, OSHA weighted each group based on the 
distribution of the labor force by age, also obtained from the BLS CPS 
(BLS, 2021d). As shown in Table IV.B.6, OSHA estimates an overall 
vaccination rate of 61.3 percent for covered employees (and 38.7 
percent unvaccinated). The healthcare sector had an earlier push to get 
healthcare workers vaccinated and has a higher current rate, estimated 
to be 70 percent.\33\
---------------------------------------------------------------------------

    \31\ The data from the CDC website was retrieved on October 4, 
2021.
    \32\ Age groups included: 18-24, 25-39, 40-49, 50-64, and 65-74. 
OSHA had not included the group 65-74 in the economic analysis of 
the Healthcare ETS this past spring because for the healthcare 
sector, using the population wide average of workers in this age 
bracket was felt would overcount the number of such workers in this 
sector. OSHA is including this group now that more of the other age 
populations have been vaccinated and those concerns are no longer as 
relevant. This ETS will therefore indicate that a slightly higher 
percentage of universe of covered employees is vaccinated than if 
that age group of 65-74 was excluded altogether, but it also 
increases the number of employees for which additional compliance 
costs are factored in. OSHA interprets the ultimate result as a more 
accurate reflection of the workplace and notes that more costs are 
included than if the age group had been excluded from the analysis.
    \33\ The agency takes a recent survey (Lazer et al., August 16, 
2021) which breaks out rates for healthcare vaccination and non-
healthcare, and rather than replacing the CDC base vaccination rate 
uses the CDC rate to make an adjustment upwards to the healthcare 
rate of 70 percent.

---------------------------------------------------------------------------



[GRAPHIC] [TIFF OMITTED] TR05NO21.007

    Based on the above, OSHA estimates that the 84.2m covered employees 
includes 52.5 million (62 percent) vaccinated employees and 31.7 
million unvaccinated employees (38 percent).
b. Adjust Baseline Vaccination for Continuing Trends
    OSHA adjusts the current vaccination rate to account for continuing 
trends in vaccinations among covered employees due to employers' 
continued implementation of vaccine mandates and other policies 
(described below), under the ETS. To make this adjustment, OSHA 
requires 1) further characterization of the set of unvaccinated 
employees in terms of their likelihood to receive the vaccine, and 2) 
specification of the extent of employer-mandated and other employer 
vaccination policies.
    Based on vaccine confidence data from CDC (CDC, October 2021a), 
13.8 percent of the population ``probably or definitely will not'' get 
the vaccine; hereafter referred to as ``vaccine-hesitant''. Since this 
group is by definition part of the currently unvaccinated, OSHA 
characterizes the currently unvaccinated (37.6 percent) as being 
comprised of those who are vaccine--hesitant (13.8 percent) and the 
remainder, who while unvaccinated, are not hesitant because they are 
not in the ``probably or definitely will not'' group (23.8 percent).
    Among those who are vaccine-hesitant, OSHA estimates that 5 percent 
of covered employees (or about 36 percent of the vaccine-hesitant), are 
hesitant due to a religious (4 percent) or medical (1 percent) 
exemption. The remaining 8.8 percent include those who are vaccine-
hesitant for other reasons. For the 4 percent estimate for religious 
exemptions, OSHA relies on data from Vermont, which removed its vaccine 
exemption for nonreligious personal beliefs in 2016 and saw the 
proportion of kindergarten students with a religious exemption rise to 
about 4 percent (Graham, September 15, 2021). In analyzing this issue, 
the agency also reviewed other religious exemption data concerning 
state workers in Oregon and Washington; the agency decided not to rely 
on these data because the Vermont data is a more accurate measure of 
the correct religious exemption rate, although the data does represent 
parents deciding on whether to claim an exemption for their child, not 
for themselves. This is because, unlike the Vermont data, the Oregon 
and Washington data contain workers that have applied, but not yet been 
accepted, for a religious exemption (O'Sullivan, September 18, 2021; 
KEZI News, September 25, 2021). In Oregon, 5 percent and in Washington 
8 percent of the employees have requested accommodations though only a 
fraction so far have been accepted. However, the data are not 
inconsistent with the Vermont data even though the process in both 
Oregon and Washington are not yet complete. For the 1 percent estimate 
for medical exemptions, OSHA relied on the Household Pulse Survey (HPS) 
conducted by the U.S. Census (U.S. Census Bureau, 2021). In Table 6a of 
the Health Tables for Week 31, September 1, 2021 through September 13, 
2021, about 1% of the US population said they would not get the vaccine 
because ``Doctor has not recommended it,'' and OSHA uses this response 
as a proxy for all medical conditions.\34\
---------------------------------------------------------------------------

    \34\ Table 6a presents that 3,884,902 of the population will not 
take the vaccine because the ``doctor has not recommended it'' out 
of a total of 38,936,606 who will not get the vaccine for any 
reason. Medical reasons are then about 10% of the general population 
that will not get the vaccine, and the ones who won't get the 
vaccine are about 10% of the whole population, giving 1% (.10 * 
.10).
---------------------------------------------------------------------------

    Table IV.B.7 presents the number of employees in each vaccination 
category, which informs OSHA's subsequent estimates of which currently 
unvaccinated employees may be vaccinated by employer-mandates, 
vaccinated under the ETS, or tested under the ETS.


[GRAPHIC] [TIFF OMITTED] TR05NO21.008

    Next, OSHA estimates the number of currently unvaccinated employees 
that are likely to become vaccinated while the ETS is in effect, based 
on their employers' policies. Based on limited data on current vaccine 
mandate implementation and forecasts for future implementation (Mishra 
and Hartstein, August 23, 2021; ASU COVID-19 Diagnostic Commons, 
October 6, 2021), OSHA estimates that 25 percent of firms in scope 
currently have a mandate, and assumes that this will rise to 60 percent 
of employers after the ETS is in place. The baseline of 25 percent is 
based on recent surveys showing a range of approximately 13-45 percent 
of employers currently requiring or planning to require vaccination 
among employees (see Willis Towers Watson, June 23, 2021; Mishra and 
Hartstein, August 23, 2021; ASU COVID-19 Diagnostic Commons, October 6, 
2021). Absent the ETS, OSHA assumes that the percentage of firms would 
remain 25 percent (with some measure of upward adjustment due to other 
federal vaccine mandates affecting select populations, as discussed 
above). To the extent more firms than OSHA estimates would mandate 
vaccination independent of the ETS and thereby increase the vaccination 
rate (again because of factors such as other federal vaccine mandates), 
then the agency's costs are overestimated because the agency's baseline 
vaccination rate is too low. The assumption of an increase from 25 to 
60 percent is based on the same set of surveys that indicate that the 
share of employers who will mandate vaccinations after the ETS 
(including those that already mandate vaccinations) range from 25-75 
percent, see above references. The agency also assumes that employees 
are distributed in the same proportion across employers with and 
without a vaccine mandate (e.g., if 60 percent of firms mandate 
vaccination, 60 percent of employees will be vaccinated due to the 
mandate (less those who remain unvaccinated due to religious or medical 
exemptions).
    OSHA assumes that all unvaccinated employees subject to an employer 
mandate will be vaccinated under that employer mandate, except for 
those seeking a medical or religious exemption. For unvaccinated 
employees not subject to an employer mandate, OSHA assumes that they 
will also be vaccinated at their employer's request, except for 
employees who are vaccine-hesitant, which includes not only those who 
remain unvaccinated for medical and religious reasons, but also those 
who are hesitant for any other reason. OSHA carries through its 
assumptions and estimates into its total cost estimates. For example, 
OSHA estimates that the 25 percent of firms in scope that currently 
have a vaccination mandate will not need to implement a new written 
policy on vaccination in response to the ETS since they will already 
have implemented a policy that meets the requirements of the ETS.
    In total, OSHA estimates that 27 percent of covered employees (22.7 
million) will be vaccinated based on employer policies under the ETS; 
or 72 percent of covered employees who are currently unvaccinated. The 
resulting vaccination rate, adjusted for the ETS, is estimated based on 
the total of those who are currently vaccinated and those who will be 
vaccinated under employer policies, 89.4 percent as shown in Table 
IV.B.8. Calculations of this nature, while not discussed in more detail 
in this analysis, are contained fully in the spreadsheets supporting 
this analysis (OSHA, October 2021a).\35\
---------------------------------------------------------------------------

    \35\ OSHA notes that these estimates differ for employees 
covered by the Healthcare ETS. OSHA calculated these estimates 
separately because, as stated above, OSHA is only taking costs for 
these employees in the last four months of the assumed 6-month 
period while the ETS remains in effect. While OSHA does not describe 
in detail how it derived estimates for employees covered by the 
Healthcare ETS in this analysis, the derivation of those estimates 
run parallel to those described above. For more information, please 
see the spreadsheets supporting this analysis. (OSHA, October 
2021a).

---------------------------------------------------------------------------


[GRAPHIC] [TIFF OMITTED] TR05NO21.009

    From Table IV.B.8, OSHA estimates that approximately 75.3 million 
(89.4 percent) of covered employees will be vaccinated when the ETS is 
in full effect, and that approximately 8.9 million employees (10.6 
percent, made up of approximately 6.3 million covered employees who 
will be tested for COVID under the ETS and approximately 2.6 million 
employees who return to telework (see next paragraph)) will remain 
unvaccinated. This final set of unvaccinated employees includes all 
employees not vaccinated because of religious or medical accommodations 
or medical contraindication, plus the portion of those who are vaccine-
hesitant for any other reason, who were not vaccinated because their 
employer has opted for a voluntary vaccination policy.
    From the above, OSHA estimates that about 5 percent of all covered 
employees will seek and receive religious or medical accommodations or 
exemption for medical contraindication. While the agency encourages 
employers to consider the most protective accommodations such as 
telework, which would prevent the employee from being exposed at work 
or from transmitting the virus at work, for cost analysis purposes the 
agency assumes these workers will largely be tested in order for their 
employers to comply with the ETS. Consistent with the overall average 
22 percent of those who returned to work after teleworking earlier in 
the pandemic (see teleworking discussion above), OSHA assumes for this 
cost analysis that only 22 percent of workers needing a reasonable 
accommodation will return to full time telework as a reasonable 
accommodation. OSHA also assumes that the 78 percent remainder will 
follow the testing/masking protocols in the ETS as a reasonable 
accommodation.
    For hesitant employees who will not seek a religious or medical 
accommodation, and who work in a firm with a testing option, the agency 
assumes as above that those who were teleworking before (again on 
average 22 percent) will return to telework rather than being tested.
c. Cost of Absenteeism to Employers
    Even mild cases of Covid-19 can be costly to employers as they can 
induce productivity losses due to work absences, both among those 
infected and their close contacts who may be subject to quarantine 
requirements. While many workers were able to engage in telework in 
March-April 2020, several occupational groups deemed essential, 
including childcare workers, personal care aids, healthcare support 
occupations, and food processing workers, exhibited significantly 
higher rates of absenteeism during that period, which the authors 
attributed to some workers contracting COVID-19 (Groenewold et al., 
July 10, 2020). Absenteeism can also affect the productivity of workers 
who are present, similar to how turnover can impose costs on incumbent 
workers (Kuhn and Yu, April 2021).
    In aggregate, productivity losses from absences can be costly, as 
evidenced by the economic losses from seasonal influenza. One estimate 
found that the United States loses 20.1 million days of economic 
productivity every year due to influenza, an ongoing loss equivalent to 
80,400 full-time worker-years (Putri et al., June 22, 2018). Another 
recent study found that higher influenza vaccination rates result in 
both fewer deaths and significantly reduced illness-related work 
absences (White, 2021).
    OSHA recognizes that absenteeism has been a problem. However, as 
explained in other sections of the preamble, the ETS vaccination and 
testing and face covering requirements are necessary to reduce the 
spread of COVID-19 in the workplace, which may in part reduce 
absenteeism. The ETS might in a limited sense also increase absenteeism 
because the rule requires employers to temporarily remove from the 
workplace any employee who receives a positive COVID-19 test or is 
diagnosed with COVID-19 by a licensed healthcare provider. However, 
this provision will also help to further reduce absenteeism because, 
when an


infected employee is promptly removed from the workplace, that can 
prevent one employee from infecting other employees in the workplace 
and potentially causing an outbreak or a super-spreader event. Thus, 
OSHA concludes that the ETS may, on net, help ameliorate absenteeism by 
reducing illnesses, but in any event will not increase absenteeism (see 
OSHA, October 2021c).
d. The Effect of Employee Turnover
    One of the primary concerns among employers in imposing vaccination 
mandates is loss of staff, with 60 percent of employers selecting it as 
a concern with regard to mandating COVID-19 vaccination, according to 
one survey (Mishra and Hartstein, August 23, 2021).\36\ To this end, 
employer vaccination mandates could lead to employee turnover; 
employees could either leave on their own volition or employers who 
have instituted strict vaccination policies may fire workers who are 
not vaccinated, or place them on unpaid leave.
---------------------------------------------------------------------------

    \36\ This survey done in August, 2021, has 1,630 responses, 
reported by HR staff, attorneys, and executives. Described as being 
``from a variety of industries,'' 83 percent of respondents were 
from companies with more than 100 employees.
---------------------------------------------------------------------------

    On the other hand, there is countervailing evidence to suggest that 
employers who implement a vaccine mandate will be met with an influx of 
potential workers. Many employees would prefer a mandate in place, and 
would be more likely to stay with, or apply to, a firm that had a 
vaccine mandate in place. For example, although Inova health system in 
Northern Virginia, lost 89 workers for noncompliance with the system's 
vaccination mandate, that loss amounted to less than 0.5 percent of its 
workforce, (Portnoy, October 3, 2021), and, in any event, Inova's CEO 
stated that the vaccine mandate has helped with recruitment, and that 
its workers are concerned for their own safety and want to know they 
are working with vaccinated colleagues. This same article listed some 
other Virginia healthcare systems with higher rates of loss in 
connection with vaccine mandates. Valley Health terminated 1 percent of 
its employees, while Luminis Health had about 2 percent of its workers 
still unvaccinated at the time of its mandate deadline. As another 
example, although United Airlines had 593 employees (out of the 
company's 67,000 U.S. employees) who had not complied with the 
company's vaccination mandate at the end of September (a number that 
dropped below 240 employees by October 1), the company reported it has 
received 20,000 applications for 2,000 flight attendant positions, a 
much higher ratio than before the pandemic (Chokshi and Scheiber, 
October 2, 2021). In addition, one survey reports that among employee 
resignations due to COVID-19 workplace policies, 42 percent reported 
lack of workplace safety policies, 17 percent reported that existing 
workplace policies were not stringent enough, and only 39 percent 
reported overly restrictive workplace policies, suggesting that many 
employees will welcome vaccine mandates (ASU COVID-19 Diagnostic 
Commons, October 6, 2021).\37\
---------------------------------------------------------------------------

    \37\ This August 2021 global survey (all results presented here 
are for the US only) has 1,143 responses. It covers 28 industries, 
including: Technology and Software, Business and Professional 
Services, Manufacturing, Construction, and Healthcare. Ninety 
percent of respondents were from companies with more than 100 
employees.
---------------------------------------------------------------------------

    While employee turnover is a natural part of business in any 
industry, higher employee turnover rate than normal can have a direct 
impact on profit and revenue. The normal range of employee turnover 
differs widely by industry, with an average turnover rate of about 50 
percent per year overall for the private sector.\38\ For example, 
between 2016 and 2020, employee turnover ranged from 55 percent to 70 
percent in the retail industry and from 40 percent to 60 percent in the 
transportation industry (the industry sectors with the highest 
employment).\39\
---------------------------------------------------------------------------

    \38\ BLS (March 11, 2021).
    \39\ Id.
---------------------------------------------------------------------------

    OSHA acknowledges that a vaccine mandate may result in increased 
employee turnover, but one recent survey \40\ suggests it is very 
unlikely that this potential increase in employee turnover will exceed 
the ranges that industries have experienced over time. The survey, 
though limited because many respondents did not have mandates in place 
at that time, shows that there was no impact on turnover for 71 percent 
of those with mandates in place. Only 25 percent saw a slight increase 
in turnover (1 percent to 5 percent above normal) and only 4 percent 
saw a significant increase (more than 5 percent above normal). As such, 
OSHA does not anticipate that the potentially increased employee 
turnover attributable to vaccine mandates will be substantial enough to 
negate normal profit and revenue.
---------------------------------------------------------------------------

    \40\ Umland, October 13, 2021. This October 2021 survey has 
1,059 total respondents, though only 365 have implemented a 
vaccination mandate and answered this turnover question.
---------------------------------------------------------------------------

    To this end, an important factor to consider in examining turnover 
in connection with vaccine mandates is the unquantified cost savings 
and other positive economic impacts accruing to employers that 
institute vaccine mandates. These include reduced absenteeism due to 
fewer COVID-19 illnesses and quarantines, as discussed above. Other 
positive economic impacts of a vaccine mandate are increased retail 
trade from customers that feel less at risk and better relations with 
suppliers and other business partners. These all would contribute to 
improved business and increased profits.
    The existence of these cost savings and other positive economic 
impacts accruing to employers that comply with the ETS suggests that 
the actual net costs of the ETS could be much lower than the costs 
reported in this section of the economic analysis. As OSHA discusses 
above, OSHA has provided evidence to support its estimate that 25 
percent of covered employers already voluntarily require that their 
employees be vaccinated and a much larger percentage are considering a 
vaccine mandate. This supports the conclusion that these businesses 
agree that doing so will ultimately save costs.
    In addition, under the ETS, employers may implement a policy that 
allows for testing and face covering instead. Firms will have a 
tendency to self-select: If a large proportion of its work force has 
indicated concern about a vaccine mandate, the firm is more likely to 
choose the testing option to retain their workers. This is one factor 
that led the agency to estimate that approximately 40 percent of 
employers will allow employees to choose testing and face coverings in 
lieu of vaccination. To the extent employers are concerned about 
employee testing costs, employers can generally absorb testing costs or 
help employees reduce those costs through low-cost assistance such as 
employer proctoring of tests (even though that is not required by this 
ETS). Departure of personnel because of vaccine mandates is also likely 
to be less common when vaccine mandates are more prevalent across 
employers in a region or industry. One survey reports that 65 percent 
of employers state that actions of other companies in their industry 
are very, or at least moderately, important in deciding to mandate 
vaccination (Mishra and Hartstein, August 23, 2021).
    Mandatory vaccinations for COVID-19 are still relatively new 
because vaccines only became available in quantities sufficient to 
support such mandates only about 6 months ago, and the FDA has only 
recently moved past emergency clearance to final clearance. While there 
is not an abundance of evidence about whether employees have actually 
left or joined an employer based on a vaccine mandate,


particularly one with an alternative allowing for testing in lieu of 
vaccination, OSHA has examined the best available evidence it could 
locate in the timeline necessary to respond with urgency to the grave 
danger addressed in this ETS. Based on that, OSHA is persuaded that the 
net effect of the OSHA ETS on employee turnover will be relatively 
small, given the option for employers to implement a testing and face 
covering policy and the countervailing forces surrounding turnover that 
will limit those effects, as discussed above.
    Finally, OSHA finds one line of evidence particularly persuasive 
because it involves data instead of polls: While different surveys may 
suggest different levels of worker intentions (joining or remaining 
with a safer employer versus leaving an employer to avoid 
vaccination),\41\ the data suggests that the number of employees who 
actually leave an employer is much lower than the number who claimed 
they might: 1% to 3% or less actually leave, compared to the 48-50% who 
claimed they would.\42\ As discussed earlier, this turnover number is 
well below the average turnover rate in most industries. Thus, OSHA 
concludes that whether or not the ETS proves helpful to recruitment 
efforts for some employers, it will not, on balance, add significant 
new costs to covered employers or threaten the economic feasibility of 
any industry during a six month period.
---------------------------------------------------------------------------

    \41\ Two polls from June 2021, when the number of COVID-19 cases 
had dropped dramatically just before the Delta Variant led to a 
surge in cases, indicated that 50% of unvaccinated employees 
surveyed said that they would leave their job rather than accept a 
vaccination mandate from their employer. (KFF et al., June 30, 2021) 
(the same percentage also responded that ``The number of cases is so 
low that there is no need for more people to get the vaccine.''). A 
separate poll from the same time also stated that 48% of ``vaccine 
hesitant'' employees claimed they would quit their jobs rather than 
be vaccinated. (Barry et al., September 24, 2021--citing yet 
unpublished June 2021 poll). In a more recent poll, about 44% of 
workers said that they would consider leaving their jobs if they 
were forced to get vaccinated, while around 38% of workers would 
consider leaving their current employer if the organization did not 
enact a vaccine mandate. (Kelly August 12, 2021). Interestingly, in 
that survey there was a direct correlation between the age of the 
worker and the desire to have a vaccinated workplace: Younger 
workers, usually the most mobile portion of the workforce, had a 
much higher desire for a vaccinated workforce (50% of Generation Z 
employees, as compared to 33% of Baby Boomers).
    \42\ An article titled ``Unvaccinated Workers Say They'd Rather 
Quit Than Get a Shot, but Data Suggest Otherwise'' noted the 48%-50% 
threat to leave, but included hard data showing nothing close to 
those levels actually occurred: Houston Methodist Hospital required 
its 25,000 workers (including its 3,580 unvaccinated employees) to 
get a vaccine by June 7, and only 153 resigned or were fired (4% of 
the 3,580 unvaccinated employees; 0.6% of the total number of 
employees); other examples of the numbers of employees who left in 
response to their employers' mandatory vaccine policy involved 5 out 
of 527 (0.9%), 2 out of 250 (0.8%), 6 out of 260 (3%), and 125 out 
of 35,800 (0.3%). (Barry et al., September 24, 2021).
---------------------------------------------------------------------------

    OSHA seeks comments on these estimates and conclusions, as well as 
further data that it could use to refine its estimates.
IV. Cost Analysis for COVID-19 Vaccination and Testing ETS, Sec.  
1910.501
    In this section, OSHA provides estimates of the per-entity and 
total costs for the requirements of this ETS. Section 6(c)(3) of the 
OSH Act states that the Secretary will publish a final standard ``no 
later than six months after publication of the emergency standard.'' 
Costs are therefore estimated over a six-month time period. Note that 
the estimates are presented in this section at the 3-digit NAICS level, 
but the analysis was conducted at the 6-digit NAICS level and 
aggregated to the 3-digit level for presentation purposes. The 6-digit 
NAICS level data is accessible in the supporting spreadsheet. It should 
be noted that this analysis deals strictly with averages. For any given 
entity, actual costs may be higher or lower than the point estimate 
shown here, but using an average allows OSHA to evaluate feasibility by 
industry as required by the OSH Act. In addition, OSHA has limited data 
on many of the parameters needed in this analysis and has estimated 
them based on the available data, estimates for similar requirements 
for other OSHA standards, consultation with experts in other government 
agencies, and internal agency judgment where necessary. OSHA's 
estimates are therefore based on the best evidence available to the 
agency at the time this analysis of costs and feasibility was 
performed.
    As mentioned above, OSHA estimates that approximately 264,000 
entities have employees who will be subject to the requirements of the 
ETS, including approximately 84.2 million employees. Many ETS 
requirements result in labor burdens that are monetized using the labor 
rates described next.
a. Wage Rates
    OSHA used occupation-specific wage rates from BLS 2020 OEWS data 
(BLS, 2021a). Within each affected 6-digit NAICS industry, OSHA 
calculated the employee-weighted average wage to be used in the 
analysis. OSHA estimated loaded wages using the BLS' Employer Cost for 
Employee Compensation data (BLS, 2021b), as well as OSHA's standard 
estimate for overhead of 17 percent times the base wage.
    Costs are estimated using three labor rates for each NAICS 
industry: The average labor rate for all employees, the labor rate for 
General and Operations Managers (SOC code 11-1021), and the labor rate 
for Office Clerks, General (SOC 43-9060). Industry-specific wage rates 
are presented in Appendix C in the accompanying document in the docket, 
``Vaccination and Testing ETS: Economic Profile and Cost Chapter 
Appendices (OSHA, October, 2021b).''
b. Rule Familiarization, Employer Policy on Vaccination, and 
Information Provided to Employees
ETS Requirements
    Section 1910.501(d)(1) of the ETS specifies that the employer must 
establish and implement a written mandatory vaccination policy. The 
employer is exempted from the requirement in paragraph (d)(1) only if 
the employer establishes and implements a written policy allowing any 
employee not subject to a mandatory vaccination policy to either choose 
to be fully vaccinated against COVID-19 or to provide proof of regular 
testing for COVID-19 in accordance with paragraph (g) of the ETS and to 
wear a face covering in accordance with paragraph (i) of the ETS.\43\
---------------------------------------------------------------------------

    \43\ Note to paragraph (d): Under federal law, including the 
Americans with Disabilities Act (ADA) and Title VII of the Civil 
Rights Act of 1964, some workers may be entitled to a reasonable 
accommodation from their employer, absent undue hardship. If the 
worker requesting a reasonable accommodation cannot be vaccinated 
against COVID-19 and/or wear a face covering because of a 
disability, as defined by the ADA, or if the vaccination, testing, 
and/or wearing a face covering conflicts with the worker's sincerely 
held religious belief, practice or observance, the worker may be 
entitled to a reasonable accommodation. For more information about 
evaluating requests for these types of reasonable accommodations for 
disability or sincerely held religious belief, employers should 
consult the Equal Employment Opportunity Commission's regulations, 
guidance, and technical assistance including at: https://www.eeoc.gov/wysk/what-you-should-know-about-covid-19-and-ada-rehabilitation-act-and-other-eeo-laws.
---------------------------------------------------------------------------

    In addition, under Sec.  1910.501(j), information provided to 
employees, the ETS requires the employer to inform each employee, in a 
language and at a literacy level the employee understand about: (1) The 
requirements of the ETS as well as any employer policies and procedures 
established to implement the ETS; (2) COVID-19 vaccine efficacy, 
safety, and the benefits of being vaccinated; (3) the requirements of 
29 CFR 1904.35(b)(1)(iv) and Section 11(c) of the OSH Act; and (4) the 
prohibitions of 18 U.S.C. 1001 and Section 17(g) of the OSH Act.
    As stated, the ETS face covering requirements are contained in 
paragraph


(i) of the ETS. Under that paragraph, the employer, with certain 
exceptions specified in the ETS, must ensure that each employee who is 
not fully vaccinated wears a face covering when indoors and when 
occupying a vehicle with another person for work purposes. The ETS does 
not require, nor does it prohibit, the employer to pay for any costs 
associated with face coverings (although employer payment for face 
coverings may be required by other laws, regulations, or collective 
bargaining agreements or other collectively negotiated agreements). 
However, the employer must permit the employee to wear a respirator 
instead of a face covering whether required or not. In addition, the 
employer may provide respirators or face coverings to the employee, 
even if not required. In such circumstances, where the employer 
provides respirators, the employer must also comply with Sec.  
1910.504, Mini respiratory protection program.
    OSHA estimates no costs associated with an employee voluntarily 
bringing in their own respirator to use instead of a face covering 
other than those costs that OSHA is estimating below in connection with 
29 CFR 1910.501(j), information provided to employees. That section 
provides, again, that the employer must inform each employee, in a 
language and at a literacy level the employee understands about the 
requirements of the ETS as well as any employer policies and procedures 
established to implement the ETS. One policy the employer would need to 
establish to implement the ETS is a policy to comply with the 
requirements of 29 CFR 1910.504 when an employee voluntarily brings in 
their own respirator. Those requirements require only that the employer 
provide certain information to the employee (see 29 CFR 1910.504(c)).
    OSHA is also estimating no costs in connection with the employer 
providing respirators to the employee. The ETS does not require the 
employer to provide respirators to employees. Therefore, any such 
provision is voluntary and not relevant to economic feasibility of this 
rule.
    The face covering provisions in paragraph (i) contain several other 
requirements, none of which have costs associated with them.
Cost Analysis Assumptions
    In this section, OSHA estimates the cost for establishing the 
employer policy on vaccination, providing required information to 
employees, and rule familiarization. OSHA assumes each entity will 
require an average one-time labor burden of 1 hour of management labor 
for rule familiarization. OSHA based this unit cost on that taken for 
rule familiarization in the Healthcare ETS (86 FR at 32496), but 
adjusted the time downward by a half-hour because this ETS is a simpler 
standard than the Healthcare ETS.
    To establish a written policy in accordance with paragraph (d) of 
the ETS, OSHA assumes a one-time average labor burden of 5 hours of 
manager time per firm. OSHA bases this estimate on its cost estimates 
in the Healthcare ETS, where OSHA estimated that development of the 
COVID-19 Plan required by that standard would take between 5 and 40 
hours (see 86 FR at 32496-32497). OSHA concludes that 5 hours is a 
reasonable estimate because the development of a written policy on 
vaccination will be much simpler than the development of the written 
COVID-19 Plan required by the Healthcare ETS (see 29 CFR 
1910.502(c)).\44\ OSHA notes, that like the Healthcare ETS (id.), the 
cost of implementing the plan for this ETS are included in the costs of 
implementing the corresponding requirements in the ETS, which are 
discussed below.
---------------------------------------------------------------------------

    \44\ The estimates for the time to create the written vaccine 
policy plan under this ETS may differ from the time to create the 
various processes under the CMS rule published elsewhere in this 
issue of the Federal Register since the requirements of what is 
needed to be included in the plans differ. For example, the CMS plan 
requires a process for ensuring the implementation of additional 
precautions to mitigate the transmission and spread of COVID-19 
while OSHA's vaccination policy requirements do not include this 
requirement.
---------------------------------------------------------------------------

    To provide information to employees in accordance with paragraph 
(j) of the ETS, OSHA assumes a one-time average labor burden per firm 
of 10 minutes of manager time. The agency expects activities like 
posting the information on a community board, mass emailing, etc., will 
satisfy this requirement.
    The total cost for rule familiarization, establishing an employer 
policy on vaccination and providing required information to employees 
is calculated as the product of:
     One-time labor burden for rule familiarization and 
establishing a policy (a total of 6 hours of manager time per entity) 
plus a one-time labor burden for providing information to employees (10 
minutes of manager time per entity);
     The labor rate for General and Operations Managers (SOC 
code 11-1021, NAICS-specific wages); and,
     The total number of covered entities.
Cost for Employer Policy on Vaccination and Information Provided to 
Employees
Costs per entity and total costs for employer policy on vaccination and 
information provided to employees are shown below in Table IV.B.9.

c. Determining Employee Vaccination Status
ETS Requirements
    Under Sec.  1910.501(e):
    Paragraph (e)(1). The employer must determine the vaccination 
status of each employee. This determination must include whether the 
employee is fully vaccinated, which is 2 weeks after the full required 
vaccine course is completed.
    Paragraph (e)(2). The employer must require each vaccinated 
employee to provide acceptable proof of vaccination status, including 
whether they are fully or partially vaccinated. Acceptable proof of 
vaccination status is:
     The record of immunization from a health care provider or 
pharmacy;
     A copy of the COVID-19 Vaccination Record Card;
     A copy of medical records documenting the vaccination;
     A copy of immunization records from a public health, 
state, or tribal immunization information system; or


     A copy of any other official documentation that contains 
the type of vaccine administered, date(s) of administration, and the 
name of the health care professional(s) or clinic site(s) administering 
the vaccine(s).
    In instances where an employee is unable to produce acceptable 
proof of vaccination, per above, a signed and dated statement by the 
employee, subject to criminal penalties for knowingly providing false 
information:
     Attesting to their vaccination status (fully vaccinated or 
partially vaccinated); and
     Attesting that they have lost and are otherwise unable to 
produce proof required by the ETS.
    Paragraph (e)(3). Any employee who does not provide one of the 
acceptable forms of proof of vaccination status in paragraph (e)(2) of 
the ETS to the employer must be treated as not fully vaccinated for the 
purpose of the ETS.
    Paragraph (e)(4). The employer must maintain a record of each 
employee's vaccination status and must preserve acceptable proof of 
vaccination for each employee who is fully or partially vaccinated. The 
employer must maintain a roster of each employee's vaccination status. 
These records and roster are considered to be employee medical records 
and must be maintained as such records in accordance with 29 CFR 
1910.1020 and must not be disclosed except as required or authorized by 
the ETS or other federal law. These records and roster are not subject 
to the retention requirements of 29 CFR 1910.1020(d)(1)(i) but must be 
maintained and preserved while the ETS remains in effect.
    Paragraph (e)(5). Finally, when an employer has ascertained 
employee vaccination status prior to the effective date of this section 
through another form of attestation or proof, and retained records of 
that ascertainment, the employer is exempt from the requirements in 
paragraphs (e)(1)-(e)(3) only for each employee whose fully vaccinated 
status has been documented prior to the effective date of this section. 
For purposes of paragraph (e)(4), the employer's records of 
ascertainment of vaccination status for each such person constitute 
acceptable proof of vaccination.
    The full costs for these provisions are taken under the costs for 
recordkeeping, discussed below, because determining vaccination status, 
providing acceptable proof of vaccination status, and creating and 
maintaining a roster of each employee's vaccination status will be part 
and parcel of the recordkeeping process.
d. Employer Support for Employee Vaccination
ETS Requirements
    Under 29 CFR 1910.501(f):
    The employer must support COVID-19 vaccination by providing:
     Time for vaccination. The employer must: (i) Provide a 
reasonable amount of time to each employee for each of their primary 
vaccination series dose(s); and (ii) provide up to 4 hours paid time, 
including travel time, at the employee's regular rate of pay for this 
purpose.
     Time for recovery. The employer must provide reasonable 
time and paid sick leave to recover from side effects experienced 
following any primary vaccination series dose to each employee for each 
dose.
    Under the ETS, fully vaccinated means (i) a person's status 2 weeks 
after completing primary vaccination with a COVID-19 vaccine with, if 
applicable, at least the minimum recommended interval between doses in 
accordance with the approval, authorization, or listing that is: (A) 
Approved or authorized for emergency use by the FDA; (B) listed for 
emergency use by the World Health Organization (WHO); or (C) 
administered as part of a clinical trial at a U.S. site, if the 
recipient is documented to have primary vaccination with the ``active'' 
(not placebo) COVID-19 vaccine candidate, for which vaccine efficacy 
has been independently confirmed (e.g., by a data and safety monitoring 
board), or if the clinical trial participant from the U.S. site had 
received a COVID-19 vaccine that is neither approved nor authorized for 
use by FDA but is listed for emergency use by WHO; or (ii) a person's 
status 2 weeks after receiving the second dose of any combination of 
two doses of a COVID-19 vaccine that is approved or authorized by the 
FDA, or listed as a two-dose series by the WHO (i.e., heterologous 
primary series of such vaccines, receiving doses of different COVID-19 
vaccines as part of one primary series). The second dose of the series 
must not be received earlier than 17 days (21 days with a 4-day grace 
period) after the first dose.
Cost Analysis Assumptions
    OSHA assumes there will be no costs to employers or employees 
associated with the vaccine itself.\45\ However, to provide support for 
vaccination of employees, OSHA estimates that it will take an average 
of 15 minutes of travel time, each way, per employee to travel to a 
vaccination site (for a total of 30 minutes). OSHA then estimates 5 
minutes to wait, fill out any necessary paperwork, and receive the 
shot, and a post-shot wait time of 20 minutes, per employee. Some 
firms, particularly larger ones, will find it cheaper to have vaccines 
administered on site. They may have an on-site health clinic or may 
hire a 3rd party purveyor to come to the facility.\46\ This will 
minimize travel and also allow the companies to mitigate some of the 
logistical issues that may be preventing employees from receiving a 
vaccine (finding a convenient appointment time, etc.). OSHA estimates 
that 10 percent of firms with employees between 100 to 500 employees 
will select this option, while, given decreased average costs 
associated with economies of scale, 25 percent of firms with over 500 
employees will select this option. OSHA was unable to obtain an 
estimate of the cost savings associated with on-site vaccination in the 
time allotted to issue this emergency standard, so it is assuming that 
the costs for off-site vaccination are the same as the costs for on-
site vaccination. This results in a likely over-estimate of costs given 
that the entities that choose the on-site option will do so as a cost-
saving measure.
---------------------------------------------------------------------------

    \45\ While there may be some administrative costs borne by the 
government, such costs are not germane to this analysis of whether 
the ETS is economically feasible for covered employers.
    \46\ Prior to the effective date of this rule, some companies 
offered on-site vaccination according to a limited survey. (Willis 
Towers Watson, June 23, 2021). See also CDC on creating an on-site 
program (CDC, March 25, 2021; CDC, October 4, 2021b).
---------------------------------------------------------------------------

    In OSHA's cost analysis, OSHA assumes that all employees will be 
vaccinated during working hours and employers would adjust the employee 
work schedule to ensure that the employee would not become eligible for 
overtime pay as a result of the vaccination time. However, it should be 
noted that, if an employee chooses to receive the vaccine outside of 
work hours, OSHA does not require employers to grant paid time to the 
employee for the time spent receiving the vaccine during non-work hours 
(although other laws may include additional requirements for employers, 
such as those addressing reasonable accommodations or exemptions). 
OSHA's analysis may be an overestimate as it reflects an assumption 
that all vaccinations are received during work hours.
    CDC data indicated that 5 percent of employees vaccinated have 
received the Johnson & Johnson vaccine, and 95 percent have received 
either Pfizer or Moderna (CDC, October 2021b). OSHA applies the same 
allocation to employees being vaccinated under the ETS. For those 
receiving Pfizer or Moderna, the labor burden outlined


above occurs twice, since vaccination requires two shots.
    The employer must provide reasonable time and paid sick leave to 
recover from side effects experienced following any vaccination dose to 
each employee for each vaccination dose. Employers may require 
employees to use paid sick leave benefits otherwise provided by the 
employer to offset these costs, if available. The average amount of 
time off an employee may need for side effects while receiving the 
vaccine doses necessary to achieve full vaccination (one or two doses, 
depending on the vaccine) depends on several factors. First, the 
percentage of people who will have side effects that are severe enough 
to require time. Second, the average time duration for those who have 
such a severe reaction. For estimates of these parameters OSHA is using 
a recent study (Levi et al., September 29, 2021) which surveyed workers 
at a state-wide health care system who had been vaccinated. The study 
found that, for the first dose, 4.9% needed administrative leave, with 
an average length of absence of 1.66 days. For the second dose, 19.79% 
needed leave and their average length of absence was 1.39 days. 
Together, the average time on leave is .36 days (.049 * 1.66 + .1979 * 
1.39) for a person receiving two doses, which reflects the fact that 
many people who receive the vaccine do not have any side effects for 
either dose while others have more severe side effects.
    In order to determine the amount of paid sick leave that would be 
available to employees, OSHA relied on data from BLS (BLS, 2021e). BLS 
estimates that for civilian workers in establishments with 100+ 
employees, 88% have access to paid sick leave (Table 33). BLS states 
that the average number of paid sick leave available is 9 days (Table 
36). Because there is the same number of days across all levels of 
employee tenure (1 year, 5 years, 10 years, and 20 years), OSHA used 9 
days for all covered employees. The agency assumes that 75% of the 
available paid sick leave has been used by the current 4th quarter of 
the calendar year. So the average number of days available is 1.98 
days: 9 (days) * 88% (employees with available paid sick leave) * 25% 
(amount of leave remaining in the year) = 1.98 days available. Given 
that the average overall time out due to side effects is 0.36 days (see 
above), OSHA concludes that, on average, employees should have 
sufficient existing paid sick leave available to cover the time needed 
as a result of vaccine-related side effects. As a result, OSHA is 
taking no costs to employers in connection with the ETS's requirement 
to provide time for recovery from vaccination (except as provided 
below), as these costs will have been incurred by the employer 
independent of the ETS.
    While this analysis is entirely consistent with OSHA's standard 
procedure of strictly using averages in cost analysis, it nonetheless 
masks some significant effects resulting from the time for recovery 
requirements. From the BLS data, OSHA knows there are 12% of 
establishments that have 100+ employees and do not provide paid sick 
leave. Correspondingly, there is a group of entities with no paid sick 
leave that will obviously incur costs that result directly from these 
requirements. In addition, some employees may not have, or some other 
entities may not offer, sufficient paid sick leave to cover these 
costs.
    To account for the 12 percent of firms that do not offer paid sick 
leave, the agency uses the above estimate of average days for two 
doses, 0.36 days, and multiplies the average employee wage by NAICS to 
calculate the cost per employee. Since OSHA does not know which firms 
make up the 12 percent, the agency spreads this total cost across all 
firms by employee. Since firms without any sick leave are likely to be 
lower-wage firms, this will likely lead to a cost overestimate.
    Therefore, the total cost for paid time off for vaccination is 
based on the costs for providing paid sick leave for the 12 percent of 
firms that do not offer paid sick leave and:
     Travel time per employee of covered firms of 15 minutes 
each way per vaccination dose (total of 30 minutes).
     Pre-shot wait time per employee of covered firms of 5 
minutes per vaccination dose.
     Post-shot wait time per employee of covered firms of 20 
minutes per vaccination dose.\47\
---------------------------------------------------------------------------

    \47\ According to the CDC, people with allergies require a wait 
time of 30 minutes, but they are a small group, and, in any event, 
the CDC recommends that routine wait time is 15 minutes, so the 
agency considers that its average of 20 minutes is probably an 
overestimate. (See CDC, October 4, 2021a; CDC, March 3,2021.)

e. COVID-19 Testing for Employees Who Are Not Fully Vaccinated
ETS Requirements
    Section 1910.501(g)(1) of the ETS requires the employer to ensure 
that each employee who is not fully vaccinated do the following:
    An employee who reports at least once every 7 days to a workplace 
where other individuals, such as coworkers or customers, are present:
     Must be tested for COVID-19 at least once every 7 days; 
and
     Must provide documentation of the most recent COVID-19 
test result to the employer no later than the 7th day following the 
date on which the employee last provided a test result.
    An employee who does not report during a period of 7 or more days 
to a workplace where other individuals, such as coworkers or customers, 
are present (e.g., teleworking for two weeks prior to reporting to a 
workplace with others):
     Must be tested for COVID-19 within 7 days prior to 
returning to the workplace; and
     Must provide documentation of that test result to the 
employer upon return to the workplace.
    Furthermore, if an employee does not provide documentation of a 
COVID-19 test result as required by paragraph (g)(1) of the ETS, the 
employer must keep that employee removed from the workplace until they 
provide a test result. In addition, when an employee has received a 
positive COVID-19 test, or has been diagnosed with COVID-19 by a 
licensed healthcare provider, the employer must not require that 
employee to undergo COVID-19 testing as required under paragraph (g) of 
this section for 90 days following the date of their positive test or 
diagnosis. Finally, the employer must maintain a record of each test 
result provided by each employee under paragraph (g)(1) of this section 
or obtained during tests conducted by the employer. These records are 
considered to be employee medical records and must be maintained as 
such records in accordance with 29 CFR 1910.1020 and must not be 
disclosed except as required or authorized by this section or other 
federal law. These records are not subject to the retention 
requirements of 29 CFR 1910.1020(d)(1)(i) but must be maintained and 
preserved while this section remains in effect.
    OSHA addresses the costs associated with testing in the next 
section. The remaining costs required by paragraph (g) are taken under 
the costs for recordkeeping, discussed below, because providing 
documentation of test results to the employer will be part and parcel 
of the recordkeeping process.
    Employees who are partially vaccinated are also required to be 
tested weekly until they are fully vaccinated. Those receiving the J&J 
vaccine will require two weeks of testing after the single shot, 
employees who received the Pfizer-BioNTech Vaccine will require 5 weeks 
of testing (3 weeks between shots and 2 weeks following the second 
shot), and Moderna recipients require 6 weeks of testing (4 weeks 
between shots and 2 weeks following the second shot) (CDC, October 4, 
2021b). Notwithstanding this, in the agency's total cost estimate OSHA 
accounts for the fact that employers need not comply with the 
requirements of this section in paragraph (g) by 60 days after the 
rule's effective date, and that employees who have completed the entire 
primary vaccination series by that date do not have to be tested, even 
if they have not yet completed the 2 week waiting period.
    There is no requirement in the rule that the employer pay for this 
testing so these testing-related costs are not included in the main 
analysis (although, as discussed below OSHA takes into account costs 
for testing in connection with the ETS's recordkeeping requirements). 
The agency estimates that 6.3 million weekly tests will need to be 
given due to this ETS (see Table IV.B.8). This 6.3 million is likely an 
overestimate of new costs because it encompasses tests for employees 
who were already required to conduct testing by their employers prior 
to this ETS.
    OSHA also notes that its cost estimates for testing do not take 
into account the 90-day break in testing that occurs following the date 
of a positive test or diagnosis. OSHA's cost estimates are also 
potentially overcounting costs in that OSHA does not take into account 
that not all employees for whom testing is required will report at 
least once every 7 days to a workplace where other individuals, such as 
coworkers or customers, are present. Thus, OSHA's estimate assumes that 
employees for whom testing is required will need to be tested at least 
once every 7 days and not less frequently as will often be the case.
    OSHA notes, in addition, that there are no costs associated with 
paragraph (g)'s removal provision. The ETS does not require the 
employer to provide paid time off to any employee for removal as a 
result of the employee's refusal/failure to provide documentation of a 
COVID-19 test result as required by paragraph (g)(1) of the ETS.
    Finally, OSHA notes that a COVID-19 test under the ETS is a test 
for SARS-CoV-2 that is: (i) Cleared, approved, or authorized, including 
in an Emergency Use Authorization (EUA), by the FDA to detect current 
infection with the SARS-CoV-2 virus (e.g., a viral test); (ii) 
Administered in accordance with the authorized instructions; and (iii) 
Not both self-administered and self-read unless observed by the 
employer or an authorized telehealth proctor. Examples of tests that 
satisfy this requirement include tests with specimens that are 
processed by a laboratory (including home or on-site collected 
specimens which are processed either individually or as pooled 
specimens), proctored over-the-counter tests, point of care tests, and 
tests where specimen collection and processing is either done or 
observed by an employer. Employers may have costs associated with 
doing, observing or proctoring employee testing, if employers choose to 
do so. However, for economic feasibility purposes, OSHA does not 
account for these costs in its estimates because they are not required 
for compliance with the ETS.
Costs Associated with Reasonable Accommodation: Testing, Face 
Coverings, and Determinations
    The ETS does not require the employer to pay for any costs 
associated with testing; however employer payment for testing may be 
required by other laws, regulations, or collective bargaining 
agreements. Thus, while OSHA does not include any costs for reasonable 
accommodation requests in its main cost analysis in recognition that 
such costs would result from the application of other laws, OSHA notes 
that even if employers were to agree to pay for COVID-19 testing as 
part of a reasonable accommodation or some other reason required by 
law, such costs would not alter OSHA's findings regarding the economic 
feasibility of the rule.\48\ OSHA reached this conclusion after 
conducting a separate analysis of reasonable accommodation costs that 
an employer might assume if they do not represent an undue hardship for 
the employer. This analysis is available in the docket at OSHA, October 
2021d.
---------------------------------------------------------------------------

    \48\ OSHA notes that while the testing required under this 
standard might be an option for employees who request a reasonable 
accommodation to avoid vaccination, other alternatives such as 
telework would be more protective to the employee by preventing 
COVID-19 exposure. These alternatives may also be available at no 
additional cost to the employer or employee.
---------------------------------------------------------------------------

    OSHA notes that this separate analysis is limited to employees who 
request accommodation, and accounts for costs of reviewing medical and/
or religious accommodation requests, as


well as costs for COVID-19 testing and face coverings that would 
satisfy the requirements of this ETS. OSHA expects a reasonable 
accommodation request could lead to a review of the employee's request 
by a manager and then a conference between the manager and the 
employee. OSHA concludes that the combination of these costs would not 
alter OSHA's findings regarding the economic feasibility of the ETS.
f. Employee Notification to Employer of a Positive COVID-19 Test and 
Removal
ETS Requirements
    Under Sec.  1910.501(h):
    Regardless of COVID-19 vaccination status or any COVID-19 testing 
required under paragraph (g) of the ETS, the employer must:
     Require each employee to promptly notify the employer when 
they receive a positive COVID-19 test or are diagnosed with COVID-19 by 
a licensed healthcare provider; and
     Immediately remove from the workplace any employee who 
receives a positive COVID-19 test or is diagnosed with COVID-19 by a 
licensed healthcare provider and keep the employee removed until the 
employee: (i) Receives a negative result on a COVID-19 nucleic acid 
amplification test (NAAT) following a positive result on a COVID-19 
antigen test if the employee chooses to seek a NAAT test for 
confirmatory testing; (ii) meets the return to work criteria in CDC's 
``Isolation Guidance'' (incorporated by reference, Sec.  1910.509); or 
(iii) receives a recommendation to return to work from a licensed 
healthcare provider.
Costs Analysis Assumptions
    The ETS does not require employers to provide paid time off to any 
employee for removal from the workplace as a result of a positive 
COVID-19 test or diagnosis of COVID-19; however paid time off may be 
required by other laws, regulations, or collective bargaining 
agreements or other collectively negotiated agreements. Therefore, 
there are no costs associated with paragraph (h)'s removal provision.
    With respect to notification, to the extent employee notification 
is connected to the ETS's testing and documentation requirements in 
paragraph (g), those costs to the employer are taken under the costs 
for recordkeeping, discussed below, because, as explained above, 
receiving documentation of test results under paragraph (g) will be 
part and parcel of the recordkeeping process.
    OSHA notes also that the costs associated with employee 
notification by vaccinated employees (not required by this ETS to 
undergo testing) should also be negligible because it will not occur 
with any real frequency. The very low breakthrough rates of infection 
among vaccinated persons suggests that the overwhelming majority of 
COVID-19 cases reported to a covered employer will be in the pool of 
unvaccinated employees.
g. Reporting COVID-19 Fatalities and Hospitalizations to OSHA
ETS Requirements
    Under Sec.  1910.501(j):
    The employer must report to OSHA:
     Each work-related COVID-19 fatality within 8 hours of the 
employer learning about the fatality.
     Each work-related COVID-19 in-patient hospitalization 
within 24 hours of the employer learning about the in-patient 
hospitalization.
    When reporting COVID-19 fatalities and in-patient hospitalizations 
to OSHA in accordance with paragraph (j)(1) of the ETS, the employer 
must follow the requirements in 29 CFR part 1904.39, except for 29 CFR 
part 1904.39(a)(1) and (2) and (b)(6).
Cost Analysis Assumptions
    OSHA estimates a total of 1,464 fatalities and 59,570 
hospitalizations for employees of covered firms.\49\ This analysis is 
broadly consistent, using updated data, with OSHA's analysis of a 
nearly identical provision in 29 CFR 1910.502, the Healthcare ETS. OSHA 
also estimates, based on the Healthcare ETS, that reporting of each 
fatality and hospitalization will require 45 minutes of an employer's 
time (86 FR at 32516). This includes hospitalizations and fatalities 
for employees that remain unvaccinated, as well as a small percentage 
of hospitalizations and fatalities of vaccinated employees due to 
breakthrough cases. Because of the timing requirements in the rule, the 
agency assumes that a hospitalization followed by a death will need two 
reports from the employer (i.e., the agency assumes that reporting for 
hospitalizations will occur within 8 hours, before reporting for 
fatalities occurs, within 24 hours). This will result in a slight over-
estimate.
---------------------------------------------------------------------------

    \49\ These counts represent hospitalizations and fatalities that 
would occur to the in-scope labor force despite the ETS. The numbers 
are derived using methodology similar to that used in Health Impacts 
to generate hospitalizations and fatalities prevented. An infection 
rate and case fatality rate are multiplied by the number of 
unvaccinated workers to derive a total number of fatalities. That 
number is used to derive hospitalizations. The number of 
hospitalizations and fatalities to vaccinated employees is 
calculated in a similar fashion, but with a lower infection rate 
because vaccination makes it considerably less likely that an 
individual will be tested and found to be infected. See (OSHA, 
October 2021a and OSHA, October 2021c). One difference in 
methodology between these counts and the Health Impacts analysis is 
that these counts use a baseline of the last 19 months of CDC data 
to estimate the case fatality rate (similar to Alternative C in the 
Health Impacts analysis), rather than a baseline of the last 6 
months (which OSHA used for the main Health Impacts analysis). This 
results in an estimate toward the upper bound for these counts 
(i.e., an overestimate of costs).
---------------------------------------------------------------------------

    The total cost for reporting COVID-19 fatalities and 
hospitalizations to OSHA is calculated as the product of:
     One-time labor burden of 45 minutes per report of 
hospitalization or fatality.
     Wage range for General and Operations Managers (SOC code 
11-1021, NAICS-specific wages).
     Total number of fatalities for employees at covered firms.
     Total number of hospitalizations for employees at covered 
firms.
Cost for Reporting COVID-19 Fatalities and Hospitalizations to OSHA
    Costs per entity and total costs for vaccination are shown below in 
Table IV.B.11.

h. Recordkeeping
ETS Requirements
    As discussed above, the full costs for the requirements in 
paragraph (e) of the ETS are taken under the costs for recordkeeping 
because determining vaccination status, providing acceptable proof of 
vaccination status, and creating and maintaining a roster of each 
employee's vaccination status will be part and parcel of the 
recordkeeping process. Under paragraph (e)(4) of the ETS, the employer 
must maintain a record of each employee's vaccination status and must 
preserve acceptable proof of vaccination for each employee who is fully 
or partially vaccinated. The employer must also maintain a roster of 
each employee's vaccination status. These records and roster are 
considered to be employee medical records and must be maintained in 
accordance with 29 CFR 1910.1020 as such records and must not be 
disclosed except as required or authorized by the ETS or other federal 
law. These records and roster are not subject to the retention 
requirements of 29 CFR 1910.1020(d)(1)(i) but must be maintained and 
preserved while the ETS remains in effect.
    With respect to vaccination, it should be noted that, under 
paragraph (e)(5) of the ETS, when an employer has ascertained employee 
vaccination status prior to the effective date of this section through 
another form of attestation or proof, and retained records of that 
ascertainment, the employer is exempt from the determination of 
vaccination requirements in paragraphs (e)(1)-(e)(3)


only for each employee whose fully vaccinated status has been 
documented prior to the effective date of this section. For purposes of 
the recordkeeping requirements in paragraph (e)(4), the employer's 
records of ascertainment of vaccination status for each such person 
constitute acceptable proof of vaccination. OSHA estimates, based on 
this provision, that 60% of employees who were vaccinated prior to the 
promulgation of the ETS will not need to document vaccination status in 
connection with paragraph (e) (ASU COVID-19 Diagnostic Commons, October 
6, 2021).
    As also discussed above, the costs for the requirements for 
documenting test results in paragraph (g), including the timing for 
when recordkeeping costs for testing accrue under the ETS, are taken 
under the costs for recordkeeping because providing documentation of 
test results to the employer will be part and parcel of the 
recordkeeping process. Under paragraph (g)(4) of the ETS, the employer 
must maintain a record of each test result provided by each employee 
under paragraph (g)(1) of the ETS or obtained during tests conducted by 
the employer. These records must be maintained in accordance with 29 
CFR 1910.1020 and must not be disclosed except as required or 
authorized by this section or other federal law. These records are not 
subject to the retention requirements of 29 CFR 1910.1020(d)(1)(i) but 
must be maintained and preserved while this section remains in effect.
    With respect to testing, it should be noted that, under paragraph 
(m) of the ETS, employers are not required to comply with the 
requirements in paragraph (g) of the ETS until 60 days after the 
effective date of the ETS, meaning that for cost analysis purposes OSHA 
assumes that employers would not receive any testing records until the 
end of that 60-day period.
    Finally, under paragraph 1910.501(l)(1) of the ETS, availability of 
records, by the end of the next business day after a request, the 
employer must make available, for examination and copying, the 
individual COVID-19 vaccine documentation and any COVID-19 test results 
for a particular employee to that employee and to anyone having written 
authorized consent of that employee. In addition, under paragraph 
1910.501(l)(2) of the ETS, by the end of the next business day after a 
request by an employee or an employee representative, the employer must 
make available to the requester the aggregate number of fully 
vaccinated employees at a workplace along with the total number of 
employees at that workplace. Under paragraph 1910.501(l)(3) of the ETS, 
the employer must also provide to the Assistant Secretary for 
examination and copying: (i) Within 4 business hours of a request, the 
employer's written policy required by paragraph (d) of the ETS, and the 
aggregate numbers described in paragraph (l)(2) of the ETS; and (ii) By 
the end of the next business day after a request, all other records and 
other documents required to be maintained by the ETS.
Cost Analysis Assumptions
    To fulfill the recordkeeping requirements in the ETS, OSHA 
estimates that it will take an average of 5 minutes of clerical time 
per employee record. OSHA bases this cost estimate on the estimate for 
recordkeeping in the Healthcare ETS (86 FR at 32515). While OSHA 
estimated an average of 10 minutes of clerical time per employee record 
in the Healthcare ETS, that standard includes more extensive 
recordkeeping requirements than what is being required under this ETS. 
See 29 CFR 1910.502(q)(2)(ii) (Healthcare ETS record must contain, for 
each instance, the employee's name, one form of contact information, 
occupation, location where the employee worked, the date of the 
employee's last day at the workplace, the date of the positive test 
for, or diagnosis of, COVID-19, and the date the employee first had one 
or more COVID-19 symptoms, if any were experienced).
    In addition, OSHA includes in this estimate 5 minutes of employee 
time to provide documentation of vaccination status or testing, as 
applicable, to the employer. OSHA notes that, for an employee who is 
vaccinated, the employer will determine the vaccination status of that 
employees and obtain acceptable proof of vaccination status at the same 
time, thus negating the need to create two separate records for these 
requirements.
    OSHA notes that there will be a cost associated with setting up the 
recordkeeping system (e.g., a spreadsheet) used to comply with the ETS. 
OSHA takes these costs in connection with the costs for the employer 
policy on vaccination, which are described above.
    Given the relative complexity of recordkeeping in the Healthcare 
ETS, OSHA has simplified its assumptions to reflect a variety of small 
costs in a combined estimate. As in the Healthcare ETS, the cost 
estimate of 5 minutes per event is likely much higher than necessary to 
account for just the actions of receiving and maintaining copies of 
records, so retaining this time will yield a tendency toward 
overestimation. However, this cost also reflects a margin to encompass 
additional outlier costs such as a second documentation of vaccination 
status for all employees who need to submit documentation twice (first 
for partial vaccination and then for full vaccination) under the ETS. 
This 5 minutes for recordkeeping also encompasses the marginal time for 
creating and maintaining a roster of each employee's vaccination status 
(paragraph (e)) and making aggregate employee data available (paragraph 
(l)). Since normally the system used for recordkeeping will be 
electronic in businesses with more than 100 employees, the time to 
create an aggregate report and a roster should be de minimis. Finally, 
this inflated recordkeeping cost encompasses time for employee 
notification to the employer of a positive COVID-19 test connected to 
the ETS's testing and documentation requirements in paragraph (g),which 
is a notification under paragraph (h). Finally, the burden of making 
available, for examination and copying, the individual COVID-19 vaccine 
documentation and any COVID-19 test results for a particular employee 
are included in this estimate because this documentation will normally 
be pulled from the electronic recordkeeping system described above.\50\
---------------------------------------------------------------------------

    \50\ The cost of providing to the Assistant Secretary for 
examination and copying the employer's written policy required by 
paragraph (d) of the ETS will be de minimis.

---------------------------------------------------------------------------


    The total cost for these requirements is calculated based on:
     One-time labor burden of 5 minutes of employee labor to 
provide documentation and 5 minutes of clerk labor per employee record 
(one record per test administered and one record per documentation of 
vaccination status).
     The average labor rate for Office Clerks, General (SOC 43-
9060, NAICS-specific wages) and employees providing documentation 
(average wage over all employees, NAICS-specific wages)
     Total number of employees at covered firms getting 
vaccinated due to the ETS with the Johnson & Johnson vaccine, who 
receive one shot.
     Total number of employees at covered firms getting 
vaccinated due to the ETS with the Pfizer-BioNTech and Moderna 
vaccines, multiplied by two to account for two shots.
     Total number of tests for employees at covered firms who 
are unvaccinated and will get vaccinated by receiving the Johnson and 
Johnson vaccine.
     Total number of tests for employees at covered firms who 
are unvaccinated and will get vaccinated by receiving the Pfizer and 
Moderna vaccines.
     Total number of employees at covered firms who are 
unvaccinated and will be tested weekly.

j. Sensitivity Analysis
    As stated above, based on limited data on current vaccine mandate 
implementation and forecasts for future implementation (Mishra and 
Hartstein, August 23, 2021; ASU COVID-19 Diagnostic Commons, October 6, 
2021), OSHA estimates that 25 percent of firms in scope currently have 
a vaccination mandate, and assumes that this will rise to 60 percent of 
covered employers after the ETS is in place. Because the agency has no 
historic reference on which to base its assumptions regarding vaccine 
mandates, the agency adjusted the percentage of firms that will 
institute a vaccine mandate because of the ETS as part of a sensitivity 
analysis. Along with


the baseline estimate of 60 percent of firms having a mandate, the 
agency looked at a vaccine mandate rate of 40 percent and 80 percent 
for covered firms, which OSHA judged to be a reasonable range based on 
the data available. The total costs associated with a 40 percent 
vaccine mandate are $2.998 billion, and the total costs associated with 
an 80 percent vaccine mandate are $2.964 billion. This compares to the 
baseline costs associated with a 60 percent vaccine mandate of $2.981 
billion. A higher vaccine mandate increases the share of employees who 
get vaccinated while reducing the share that must get weekly testing. 
It is this shift in shares that causes the costs to change because the 
total costs associated with weekly testing (recordkeeping) are more 
expensive than the total costs associated with vaccination under the 
ETS (employer support for vaccination, recordkeeping).

V. ETS Economic Feasibility Determination
a. OSHA's Screening Tests for Economic Feasibility
    As noted in the introduction to the economic analysis, an OSHA 
standard is economically feasible when industries can absorb or pass on 
the costs of compliance without threatening industry's long-term 
profitability or competitive structure, Cotton Dust, 452 U.S. at 530 
n.55, or ``threaten[ing] massive dislocation to, or imperil[ing] the 
existence of, the industry.'' United Steelworkers of Am. v. Marshall 
(Lead I), 647 F.2d 1189, 1272 (D.C. Cir. 1981).
    To determine whether a rule is economically feasible, OSHA 
typically begins by using two screening tests to determine whether the 
costs of the rule are beneath the threshold level at which the economic 
feasibility of an affected industry might be threatened. The first 
screening test is a revenue test. While there is no hard and fast rule 
on which to base the threshold, OSHA generally considers a standard to 
be economically feasible for an affected industry when the annualized 
costs of compliance are less than one percent of annual revenues. The 
one-percent revenue threshold is intentionally set at a low level so 
that OSHA can confidently assert that the rule is economically feasible 
for industries that are below the threshold (i.e., industries for which 
the costs of compliance are less than one percent of annual revenues). 
To put the one-percent threshold into perspective, OSHA calculated the 
average compounded annual rate of growth or decay in average revenues 
over the 15-year period from 2002 to 2017 (inflated to 2005 to 2020 
dollars) for firms with 100 or more employees in the 479 NAICS (out of 
546) industries covered by this ETS for which Census data were 
available and found that the average annual real rate of change in 
revenues in absolute terms for the average firm was 2.2 percentage 
points a year.\51\ In other words, revenues are generally observed to 
change by well more than one percent per year, on average, for firms 
with 100 or more employees in covered industries, indicating that 
changes of this magnitude are normal in these industries and that 
covered firms are typically able to withstand such changes over the 
course of a year, much less six months. As discussed below, the average 
percentage change due to this ETS for all covered NAICS is a fraction 
of this fluctuation in revenues.
---------------------------------------------------------------------------

    \51\ These results are presented in the Excel ETS Revenue 
Threshold Test Tables available in the Docket for this ETS. The data 
used for six-digit NAICS were from the Bureau of the Census, 
available every five years (2002, 2007, 2012, 2107).
---------------------------------------------------------------------------

    The second screening test that OSHA traditionally uses to consider 
whether a standard is economically feasible for an affected industry is 
if the costs of compliance are less than ten percent of annual profits 
(see, e.g., OSHA's economic analysis of its Silica standard, 81 FR 
16286, 16533 (March 25, 2016); upheld in N. Am.'s Bldg. Trades Unions 
v. OSHA, 878 F.3d 271, 300 (D.C. Cir. 2017)). The ten-percent profit 
test is also intended to be at a sufficiently low level so as to allow 
OSHA to identify industries that might require further examination. 
Specifically, the profit screen is primarily used to alert OSHA to 
potential impacts on industries where the price elasticity of demand 
does not allow for ready absorption of new costs in higher prices 
(e.g., industries with foreign competition where the American firms 
would incur costs that their foreign competitors would not because they 
are not subject to OSHA requirements). In addition, setting the 
threshold for the profit test low permits OSHA to reasonably conclude 
that the rule would be economically feasible for industries below the 
threshold. To put the ten-percent profit threshold test into 
perspective, evidence used by OSHA in its 2016 OSHA silica rule 
indicates that, for the combined affected manufacturing industries in 
general industry and maritime from 2000 through 2012, the average year-
to-year fluctuation in profit rates (both up and


down) was 138.5 percent (81 FR 16545).\52\
---------------------------------------------------------------------------

    \52\ Profits are subject to the dynamics of the overall economy. 
Many factors, including a national or global recession, a downturn 
in a particular industry, foreign competition, or the increased 
competitiveness of producers of close domestic substitutes are all 
easily capable of causing a decline in profit rates in an industry 
of well in excess of ten percent in one year or for several years in 
succession (See OSHA, March 24, 2016).
---------------------------------------------------------------------------

    When an industry ``passes'' both the ``cost-to-revenue'' and 
``cost-to-profit'' screening tests, OSHA is assured that the costs of 
compliance with the rule are economically feasible for that industry. 
The vast majority of the industries covered by the ETS fall into this 
category.
    A rule is not necessarily economically infeasible, however, for the 
industries that do not pass the initial revenue screening test (i.e., 
those for which the costs of compliance with the rule are one percent 
or more of annual revenues), the initial profit screening test (i.e, 
those for which the costs of compliance are ten percent or more of 
annual profits), or both. Instead, OSHA normally views those industries 
as requiring additional examination as to whether the rule would be 
economically feasible (see N. Am.'s Bldg. Trades Unions v. OSHA, 878 
F.3d at 291). OSHA therefore conducts further analysis of the 
industries that ``fail'' one or both of the screening tests in order to 
evaluate whether the rule would threaten the existence or competitive 
structure of those industries (see United Steelworkers of Am., AFL-CIO-
CLC v. Marshall, 647 F.2d 1189, 1272 (D.C. Cir. 1980)).
Time Parameters for Analysis
    OSHA's economic analyses almost always measure the costs of a 
standard on an annual basis, conducting the screening tests by 
measuring the cost of the standard against the annual profits and 
annual revenues for a given industry. One year is typically the minimum 
period for evaluating the status of a business; for example, most 
business filings for tax or financial purposes are annual in nature.
    Some compliance costs are up-front costs and others are spread over 
the duration of the ETS; regardless, the costs of the rule overall will 
not typically be incurred or absorbed by businesses all at once. 
However, OSHA does not expect that the ETS will require employers to 
incur initial capital costs for equipment to be used over many years 
(which would typically be addressed through installments over a year or 
a longer period to leverage loans or payment options to allow more time 
to marshal revenue and minimize impacts on reserves).
    The compliance costs for this ETS are for a temporary rule for a 
period of six months (which, again, is the time period that OSHA 
assumes this ETS will last, solely for economic purposes). While OSHA 
believes the most appropriate screens would be based on annual profits 
and revenue, it has followed the more cautious route of basing the 
screens on 6 months of profits and revenues to avoid any potential 
uncertainty about whether the ETS is economically feasible for the 
industries covered by this ETS. Using one year of revenues and profits 
as the denominators in the cost-to-revenue and cost-to-profit ratios 
would have resulted in ratios that are half of the estimated ratios 
presented in this analysis. It is therefore unsurprising that 
businesses in some number of NAICs have edged above the profit-
thresholds using a 6 month screen (as will be discussed later), and 
OSHA believes that edging above the screening thresholds is less of an 
indicator of economic peril in this context than in the context of a 
permanent rulemaking analysis. Nevertheless, OSHA has examined each of 
the NAICS that did not clear either of these conservative screening 
tests and has concluded that the ETS is economically feasible for each 
one.
Data Used for the Screening Tests
    The estimated costs of complying with the ETS, which OSHA relied 
upon to examine feasibility is based on the two tests described above 
(see OSHA, October 2021a). The revenue numbers used to determine cost-
to-revenue ratios were obtained from the 2017 Economic Census for firms 
with 100 or more employees in covered industries. This is the most 
current information available from this source, which OSHA considers to 
be the best available source of revenue data for U.S. businesses.\53\ 
OSHA adjusted these figures to 2020 dollars using the Bureau of 
Economic Analysis's GDP deflator, which is OSHA's standard source for 
inflation and deflation analysis.
---------------------------------------------------------------------------

    \53\ For information regarding the standards and practices used 
by the Census Bureau to ensure the quality and integrity of its 
data, see (US Census Bureau, October 8, 2021a; US Census Bureau, 
October 8, 2021b).
---------------------------------------------------------------------------

    The profit screening test for feasibility (i.e., the cost-to-profit 
ratio) was calculated as ETS costs divided by profits. Profits were 
calculated as profit rates multiplied by revenues. The before-tax 
profit rates that OSHA used were estimated using corporate balance 
sheet data from the Internal Revenue Service (IRS), 2013 Corporation 
Source Book (IRS, 2013). The IRS discontinued the publication of these 
data after 2013, and therefore the most current years available are 
2000-2013.\54\ The most recent version of the Source Book represents 
the best available evidence for these data on profit rates.\55\
---------------------------------------------------------------------------

    \54\ See IRS, 2013.
    \55\ OSHA also investigated Bizminer and RMA as potential 
sources of profit information and determined that they do not 
represent adequate and random samples of the affected industries.
---------------------------------------------------------------------------

    For each of the years 2000 through 2013, OSHA calculated profit 
rates by dividing the ``net income'' from all firms (both profitable 
and unprofitable) by total receipts from all firms (both profitable and 
unprofitable) for each NAICS.\56\ OSHA then averaged these rates across 
the 14-year (2000 through 2013) period. Since some data provided by the 
IRS were not available at disaggregated levels for all industries and 
profit rates, data at more highly aggregated levels were used for some 
industries; that is, where data were not available for each six-digit 
NAICS code, data for the corresponding four- or five-digit NAICS codes 
were used. Data were used for all firms in the NAICS (as opposed to 
just firms with 100 or more employees) since data disaggregated by 
employment size-class were not available. Profit rates are expressed as 
a percentage (see OSHA, October 2021a). Profits themselves were used to 
calculate the cost-to-profit estimates for all firms contained in a 
particular NAICS code (see OSHA, October 2021a).
---------------------------------------------------------------------------

    \56\ There is one code reported per tax entity and it may not be 
representative to the six-digit level. See Corporation Sourcebook on 
limitations of the industry classification for details. (IRS, 2013).
---------------------------------------------------------------------------

    OSHA has estimated costs over a 6-month timeframe for this ETS. As 
discussed above, OSHA has therefore used six months of revenue to 
conduct the cost-to-revenue tests and six months of profit to conduct 
the cost-to-profit tests.
General Use of Revenues and Profits To Measure Economic Feasibility
    As with other OSHA rulemaking efforts, the agency relies on the two 
screening tests (costs less than one percent of revenue and costs less 
than ten percent of profit) as an initial indicator of economic 
feasibility. OSHA has generally found that the cost-to-revenue test is 
a more reliable indicator of feasibility simply because the revenue 
data are more accurate than the profit data. There are several reasons 
for this.
    First, OSHA has been using corporate balance sheet data from the 
IRS as the best available evidence for estimating


corporate profits for years.\57\ Nevertheless, because firms typically 
have an incentive to minimize their tax burden, it is reasonable to 
expect that some of the reported accounting data may have been 
strategically adjusted to reduce reported profits and their associated 
tax implications. Business profits are much more likely to reflect such 
strategic accounting than business revenues; accordingly, revenues are 
a more accurate measure than profits for evaluating economic 
feasibility for a multitude of reasons.\58\
---------------------------------------------------------------------------

    \57\ OSHA funded and accepted a final report by Contractor Henry 
Beale (Beale Report, 2003) that reviewed alternative financial data 
sources and concluded that the IRS data were the best. Since then 
OSHA has been relying on IRS data to provide the financial data to 
support its rulemaking analyses. See, for example, Occupational 
Safety and Health Administration (OSHA) (2016), Final Economic and 
Regulatory Flexibility Analysis for OSHA's Rule on Occupational 
Exposure to Respirable Crystalline Silica, Chapter VI, pp. VI-2 to 
VI-3, Docket No. OSHA-2010-0034-4247 (OSHA, March 24, 2016), which 
includes a more recent review of data sources for corporate 
financial profit data and further support for OSHA's choice of IRS 
data.
    \58\ In fact, all other Department of Labor agencies rely solely 
on revenues to assess economic impacts, such as Regulatory 
Flexibility Act certifications, in their rulemakings (see, e.g., 
Employment and Training Administration, Final Rule on Strengthening 
Wage Protections for the Temporary and Permanent Employment of 
Certain Aliens in the United States, https://www.govinfo.gov/content/pkg/FR-2021-01-14/pdf/2021-00218.pdf; Wage and Hour 
Division, Tip Regulations Under the Fair Labor Standards Act (FLSA), 
https://www.govinfo.gov/content/pkg/FR-2020-12-30/pdf/2020-28555.pdf).
---------------------------------------------------------------------------

    Second, because OSHA is using data from both profitable and 
unprofitable firms, the average profit rate for a small number of 
industries is negative (as described above, using 14 years of data that 
predate the pandemic). This result could have occurred because of the 
way profits are calculated, which unnaturally skews average profit 
rates downward by including firms that have large losses (negative 
profits) or subnormal profits and have already closed or are in the 
process of closing, irrespective of any action by OSHA. The negative 
rates could also be the result of macroeconomic fluctuations during the 
14-year period used to determine the average, a period in which some of 
these industries may have experienced unusually adverse financial 
impacts (see, e.g., the explanation in Chapter VI, pp. VI-20 of the 
Final Economic and Regulatory Flexibility Analysis for OSHA's Rule on 
Occupational Exposure to Respirable Crystalline Silica, Docket No. 
OSHA-2010-0034-4247, which notes the skew from negative impacts during 
recession years (OSHA, March 24, 2016)). Or they could result from tax-
related incentives, as previously noted.
    Whatever the reason, the cost-to-profit calculations for NAICS with 
negative profit rates fail to provide reliable information about the 
long-term profitability of these industries, independent of the ETS. 
Companies and industries that consistently lose money do not typically 
stay in business, and would almost certainly not still be in business 
in 2021 if that loss continued at the same level for each of the 8 
years since the profit data was published in 2012. Revenue streams are 
a more dependable measure for those firms because those streams tend to 
be more stable and more indicative of the actual capabilities of 
sustainable firms than reported negative profit margins. As a result, 
for the purposes of this analysis, OSHA has relied more heavily on its 
cost-to-revenue estimates, in lieu of cost-to-profit estimates, as the 
more reliable indicator for economic feasibility for the industries 
with negative profit rates.
    Third, and similarly, profit rates that are only slightly positive 
(i.e., less than one percent) are inconclusive and not useful for the 
purpose of OSHA's cost-to-profit test. In economics terms, profit 
entails a reasonable rate of return on investment, and long-term 
profits of less than one percent a year are not generally reasonable 
for firms that expect to remain in business. Thus data showing 
industry-wide profits in this range do not measure the true ability of 
companies to pay for the ETS costs. As previously stated, revenue 
streams tend to be more stable and more indicative of the actual 
capabilities of sustainable firms. Therefore, where possible, OSHA 
prefers to rely on the cost-to-revenue test to evaluate economic 
feasibility for industries that have a less than one percent profit 
rate.
    The qualification, and by far the most important reason for the 
general primacy of revenues versus profits as the appropriate metric 
for determining economic feasibility, for most OSHA rules, is that the 
regulated firms are able to pass on the costs of the rule in the form 
of higher prices. When they cannot, the profit test functions primarily 
as a screen for a limited purpose: Alerting OSHA to potential impacts 
where unregulated competitors can prevent firms from passing costs 
along to customers.
    To understand this point, some economic background is needed. The 
price elasticity of demand refers to the relationship between the price 
charged for a product or service and the quantity demanded for that 
product or service: The more elastic the relationship, the larger the 
decrease in the quantity demanded for a product when the price goes up. 
When demand is elastic, establishments have less ability to pass 
compliance costs on to customers in the form of a price increase and 
must absorb such costs in the form of reduced profits. In contrast, 
when demand is relatively inelastic, the quantity demanded for the 
product or service will be less affected by a change in price. In such 
cases, establishments can recover most of the variable costs of 
compliance (i.e., costs that are highly correlated with the amount of 
output) by raising the prices they charge; under this scenario, if 
costs are variable rather than fixed, business activity and profit 
rates are largely unchanged for small changes in costs. Ultimately, 
where demand is relatively inelastic, any impacts are primarily borne 
by those customers who purchase the relevant product or service for a 
slightly higher price. Most of the costs of this ETS are variable costs 
because they depend primarily on the level of production or the number 
of employees at an establishment. For example, under the ETS, a firm 
with 500 employees must determine and record the vaccination status of 
500 employees, while a firm with 250 employees need determine and 
record the vaccination status of only 250 employees.\59\
---------------------------------------------------------------------------

    \59\ While fixed cost can be more limiting in terms of options 
for businesses, most of the costs of this rule are not fixed. 
Instead, most of the compliance costs vary with the level of output 
or employment at a facility.
---------------------------------------------------------------------------

    In general, ``[w]hen an industry is subjected to a higher cost, it 
does not simply swallow it; it raises its price and reduces its output, 
and in this way shifts a part of the cost to its consumers and a part 
to its suppliers'' (Am. Dental Ass'n v. Sec'y of Labor, 984 F.2d 823, 
829 (7th Cir. 1993)). A reduction in output could happen in a variety 
of ways: Individual establishments could reduce their levels of service 
(e.g., retail firms) or production (e.g., manufacturing), both of which 
could take the form of a reduction of worker hours; some marginal 
establishments could close; or, in the case of an industry with high 
turnover of establishments, new entry could be delayed until demand 
equals supply. In many cases, a decrease in overall output for an 
industry will be a combination of all three kinds of reductions. The 
primary means of achieving the reduction in output most likely depends 
on the rate of turnover in the industry and on the form that the costs 
of the regulation take. Further, the temporary nature of the ETS and 
its associated


costs suggests that firms may have more flexibility to respond than 
when facing a permanent increase in costs. For example, firms may be 
able to temporarily increase prices or temporarily defer planned 
capital expenditures or other maintenance to cover compliance costs.
    There are two situations typically mentioned when an industry 
subject to regulatory costs might be unable to pass those costs on: (1) 
Foreign competition not subject to the regulation, or (2) domestic 
competitors in other industries, not subject to the regulation, that 
produce goods or services that are close substitutes. Otherwise, when 
all affected domestic industries are covered by a rule and foreign 
businesses must also comply with the rule or are unable to compete 
effectively, the ability of a competing industry to offer a substitute 
product or service at a lower price is greatly diminished.
    There is a third situation that is relevant to this ETS--when only 
some firms in a domestic industry (in this case, only employers with 
100 or more employees) are subject to the ETS and its regulatory costs. 
In principle, competition from smaller employers in a NAICS could 
prevent the larger employers from passing on their costs in the form of 
higher prices and instead require them to absorb the costs in the form 
of lost profits. There are, however, several important caveats:
    1. As a practical matter, it is implausible to expect that covered 
employers (with 100 or more employees) would feel constrained by 
smaller competitors in their industry so as not to pass on costs for a 
rule lasting 6 months that imposes costs equal to 0.02 percent of 
revenues, on average across all NAICS, over that time period (see OSHA, 
October 2021a). This time period would likely be too short for small 
firms to expand to take business away from the larger firms or for new 
firms to form to take advantage of such minor and transitory business 
opportunities. Furthermore, smaller firms (particularly very small 
firms--those with fewer than 20 employees) typically can't compete on 
price with large firms that have cost advantages due to various 
economies of scale; as a result, smaller firms often serve a 
specialized niche market rather than compete directly with larger 
firms. To the extent that this ETS creates new business opportunities 
for these smaller uncovered firms, they would also be covered by the 
ETS as soon as they reached 100 employees.\60\
---------------------------------------------------------------------------

    \60\ This cost advantage may be exaggerated or non-existent in 
many cases (see the discussion directly below in the text in Caveat 
2).
---------------------------------------------------------------------------

    2. An important factor to consider in calculating the costs and 
impacts and economic feasibility of this ETS is the unquantified and 
unmonetized cost savings and other positive economic impacts accruing 
to employers that comply with the ETS. These include reduced 
absenteeism due to COVID-19 illnesses \61\ and quarantine.\62\ Other 
positive economic impacts that compliant employers would enjoy from a 
safer business environment are increased retail trade from customers 
that feel less at risk and better relations with suppliers and other 
business partners. These all would contribute to improved business and 
increased profits.
---------------------------------------------------------------------------

    \61\ Several occupational groups less able to avoid exposure to 
SARS-CoV-2 infection exhibited significantly higher rates of 
absenteeism in March-April 2020 compared to earlier periods 
(Groenewold et al., July 10, 2020).
    \62\ For a discussion of turnover (i.e. whether the ETS could 
affect the likelihood that an employee will remain with an employer, 
either because the imposition of a vaccine requirement will lead 
some employees to leave and find employment at an establishment not 
subject to the ETS, or, alternatively, to stay due to a preference 
for enhanced COVID-19 safety procedures), please see the cost 
section (Section III.d.) of this economic analysis.
---------------------------------------------------------------------------

    3. The existence of these cost savings and other positive economic 
impacts accruing to employers that comply with the ETS suggests that 
the actual net costs of the ETS will be much lower than the costs 
reported in the supporting economic analysis for this ETS used to 
estimate cost impacts and demonstrate economic feasibility. In fact, 
for some share of covered employers, the net costs of the ETS may well 
be negative. Indeed, this is being confirmed by revealed preference in 
the market. Elsewhere in the economic analysis for this ETS (Cost 
Analysis section 4.2), OSHA has provided evidence to support its 
estimate that 25 percent of covered employers already voluntarily 
require that their employees be vaccinated and a much larger percentage 
are considering a vaccine mandate. This strongly supports the 
conclusion that these businesses agree that doing so will ultimately 
save costs.
b. Economic Feasibility Analysis and Determination
    This section summarizes OSHA's feasibility findings for industries 
covered by the ETS. As stated previously, the agency uses two screening 
tests (costs less than one percent of revenue and costs less than ten 
percent of profit) as an initial indicator of economic feasibility. In 
this section, OSHA discusses the industries that fall above the 
threshold level for either screening test.
    The overall effect of compliance with the general section of the 
ETS on covered industries is very small (see OSHA, October 2021a). The 
vast majority of the covered NAICS have very low cost-to-revenue and 
cost-to-profit ratios, with the overall averages being 0.02 percent of 
revenues and 0.49 percent of profits. To put this into perspective, if 
the average firm decided to raise prices to cover the costs of the ETS, 
the price of a $100 product or service, for example, would have to be 
increased by 2 cents (during the six-month period).
    Based on the information presented here, the costs of the ETS are 
below both the threshold revenue test (1 percent of revenues) and the 
threshold profit test (10 percent of profits) for the vast majority of 
NAICS industries.\63\ This indicates that the average firm in these 
industries will be able either to raise prices to cover ETS costs or to 
absorb the costs of the ETS out of available profits. In either case, 
OSHA concludes that the ETS is economically feasible for all of these 
industries.
---------------------------------------------------------------------------

    \63\ By OSHA's calculation, 524 out of the 546 six-digit NAICS 
covered by the ETS.
---------------------------------------------------------------------------

    Critically, there are no industries covered by the general section 
of the ETS that are above OSHA's cost-to-revenue threshold level of one 
percent and most are a small fraction of this level. Because OSHA is 
using data from both profitable and unprofitable firms, the average 
profit rate for a small number of industries is negative. There are 14 
NAICS with negative cost-to-profit ratios, resulting from negative 
average profit rates. These industries with negative profit rates are 
domestic service industries that are not subject to international 
competition.
    There are eight six-digit NAICS industries, covering all 
establishments in those industries covered by the general section of 
the ETS, with cost-to-profit ratios above 10 percent:
    1. NAICS 221118--Other Electric Power Generation, 23.97 percent;
    2. NAICS 488119--Other Airport Operations, 18.41 percent;
    3. NAICS 488410--Motor Vehicle Towing, 15.75 percent;
    4. NAICS 488490--Other Support Activities for Road Transportation, 
14.32 percent;
    5. NAICS 713920--Skiing Facilities, 13.16 percent; and


    6. NAICS 713940--Fitness and Recreational Sports Centers, 12.33 
percent;
    7. NAICS 713120--Amusement Arcades, 11.18 percent; and
    8. NAICS 488320--Marine Cargo Handling, 10.03 percent.
    The average profit rate reported over the 14 years for which OSHA 
has profit data for all the NAICS affected by the ETS is 4.2 percent. 
All of the eight NAICS industries with a cost-to-profit ratio above the 
10 percent threshold report an annual profit rate below one percent--75 
percent or more below the overall average for all NAICS covered by the 
ETS. These eight industries all provide domestic services and are not 
subject to international competition.
    The fact that the covered firms in these 22 NAICS industries (the 
14 with negative cost-to-profit ratios and the 8 with more sustainable 
cost-to-profit ratios) exceeded the profit screen suggests that they 
might in theory have difficulty paying for the costs of the ETS out of 
profits gained over the six-month duration of the ETS if they had no 
savings or access to capital, but even if that were true it would be 
highly unlikely to place the firms in financial jeopardy. OSHA examines 
these industries more closely below, but before even considering the 
reasons in NAICs-specific analysis it is important to consider the 
larger context. For the ETS to threaten the economic solvency of these 
firms, the following 3 conditions must apply:
    1. These firms must not enjoy certain cost savings and positive 
economic impacts from the ETS that would partially or totally offset 
their costs. This condition is questionable because of the estimated 25 
percent of employers sampled that reported voluntarily imposing a 
vaccine mandate and the substantial number more contemplating the 
voluntary adoption of such a mandate. They can be expected to base 
their decisions, partly or entirely, on anticipated cost savings or 
positive economic impacts (which would reduce or eliminate their risk 
of insolvency due to the ETS).
    2. These firms (all with 100 or more employees) must not be able to 
raise prices to cover ETS costs because of the threat that smaller 
firms in their NAICS industry, not covered by the ETS, could underprice 
them and take away their business. This condition is unlikely or 
limited because of the economies of scale the larger firms enjoy and 
the fact that the smaller firms out of necessity tend to serve a market 
niche not in direct competition with the larger firms. Also, there is a 
severe limit to the extent that firms with fewer than 100 employees can 
take away significant portions of business from the larger firms 
without becoming subject to the requirements of the rule themselves. If 
the larger firms do not feel threatened by being underpriced by smaller 
firms in these NAICS industries, then they could raise prices an 
average of less than 0.05 percent \64\ to cover the cost of the ETS--a 
small fraction of the 1.0 percent of revenues threshold (beneath which 
OSHA has determined that economic feasibility is not a concern).
---------------------------------------------------------------------------

    \64\ If not underpriced by smaller firms, covered firms in the 8 
NAICS industries reporting ETS costs above 10 percent of profits 
could cover these costs by raising prices an average of 0.08 percent 
(highest, 0.11 percent); covered firms in the 14 NAICS industries 
reporting negative profits could cover ETS costs with a price 
increase of 0.01 percent (highest, 0.02 percent).
---------------------------------------------------------------------------

    3. These firms must not generate sufficient profits or have 
adequate borrowing capacity during the six months the ETS is in force 
to cover the costs of the ETS. There are several reasons to doubt that 
this condition broadly applies. First, the estimates of business 
profits come from corporate balance sheet data that firms report to the 
IRS. But, as previously noted, it is generally the case that firms have 
an incentive to minimize their tax burden, and it is reasonable to 
expect that some of the reported accounting data may have been 
strategically adjusted to reduce reported profits and their associated 
tax implications. Another point concerning the IRS data is that they 
include the negative profits of firms that are going out of business or 
have since gone out of business. To the extent that these points are 
true, many or most of the covered firms in these NAICS industries 
(still in business) actually would generate sufficient profit to cover 
the cost of the ETS. A related point is that for this condition to 
apply, the firms must not be able to borrow the money to pay for the 
costs of the ETS. Recall, however, that these are all large firms with 
100+ employees. It is reasonable to expect that many or most firms of 
this size in the 22 NAICS industries at issue either have available 
funds or could obtain a short-term loan to cover costs equal to the 
0.01 to 0.11 percent of revenues that these firms would incur over the 
six-month period that OSHA assumes the ETS will remain in effect. Firms 
of this size normally have banking relationships and some unencumbered 
assets. They also have access to national and international capital 
markets. If these firms can borrow funds to pay for the ETS, then the 
profit restriction doesn't matter.
    Finally, OSHA anticipates concern that limiting the scope of the 
ETS to employers with 100 or more employees will somehow put these 
larger firms in economic jeopardy from the smaller firms to which the 
ETS does not currently apply. This is highly improbable for several 
reasons discussed earlier, including the fact that these are large 
employers with advantages of economies of scale and access to capital 
and the fact that this is a temporary standard that would result, at 
most, in marginal impacts over 6 months (on average, equal to costs of 
0.02 percent of revenues, which, again, translates to a cost increase 
of a penny on a fifty dollar item).
    But even that misses the main point: Economic feasibility refers to 
the industry, not to the firm. OSHA must construct a reasonable 
estimate of compliance costs and demonstrate a reasonable likelihood 
that these costs will not threaten the existence or competitive 
structure of an industry, even if it does portend disaster for some 
marginal firms (Lead I, 647 F.2d at 1272). In the (again) highly 
unlikely event that individual firms exit an industry and are replaced 
by other firms in the industry, then the ETS would preserve the 
economic feasibility of the covered industries. If an employer covered 
by this standard actually had to increase its prices slightly to 
account for the cost of this standard, there are two potential groups 
of smaller businesses that could seek to supplant the covered firms. 
The first group of businesses are much smaller than the covered firms. 
Those businesses, however, will typically have higher costs and prices 
to begin with due to their scale disadvantages to the larger firms. The 
larger firm's small price increases attributable to this ETS would not 
be likely to create an actionable competitive advantage for this group 
of smaller businesses. The second group of businesses are those closer 
in size to the 100-employee cutoff. If the marginal price increases did 
actually cause some of the larger firms to fail and the slightly 
smaller firms to take their place, the industry itself would not suffer 
a massive dislocation or be imperiled. And, of course, if all of the 
firms in an industry are large employers with 100 or more employees, no 
competitive disadvantage from within the industry would exist (even 
hypothetically), and there would be no question that they could cover 
the cost of ETS by raising prices to customers accordingly.
    Although the preceding discussion demonstrates that the ETS is 
economically feasible, OSHA has provided an additional examination of 
each of the NAICS that have crossed the profit screen (again noting 
that none of


these failed the revenue screen): The eight NAICS industries with 
positive profit ratios but profit rates below 1 percent.
1. NAICS 221118--Other Electric Power Generation, 23.97 Percent
    This U.S. industry comprises establishments primarily engaged in 
operating electric power generation facilities (except hydroelectric, 
fossil fuel, nuclear, solar, wind, geothermal, biomass). These 
facilities convert other forms of energy, such as tidal power, into 
electric energy. The electric energy produced in these establishments 
is provided to electric power transmission systems or to electric power 
distribution systems.
    Using tides to generate power is not yet economically viable, 
according to one source, because ``[t]otal availability of tidal power 
is restricted by its relatively high cost and limited number of sites 
having high flow velocities and tidal ranges,'' although ``with [ ] 
recent advancements in tidal technologies, the total availability of 
tidal power in terms of turbine technology as well as design may be 
higher than before, and the economic costs may be reduced significantly 
to competitive levels.'' In support, in the same article, ``recent 
reports state that the UK, which has the largest tidal and wave 
resource in Europe, is capable of harnessing up to 153GW of tidal power 
capacity with the help of three types of technologies and thus meeting 
20% of current UK electricity demand and reducing carbon emissions. 
Hence it is evident that wave and tidal energy could contribute more to 
the increasing electricity demands across the globe.'' \65\
---------------------------------------------------------------------------

    \65\ See Walker, January 22, 2013.
---------------------------------------------------------------------------

    At the time OSHA obtained the most recent NAICS data, there were 7 
affected entities in this NAICS industry. The entities in this NAICS 
industry include firms like Berkshire Hathaway Energy Company, (with 
annual sales of $19.8 billion, whose ``portfolio consists of locally 
managed business that share a vision for a secure and sustainable 
energy future''); Dominion Energy (with annual sales of $13.4 billion); 
and other leading firms in this industry including some of the largest 
power generation companies in the US (See NAICS Association, 2018a; 
NAICS Association 2018d; and NAICS Association 2018e).
    As this NAICS industry is not yet viable, (in the United States, at 
least), it is to be expected that revenues and profits would be low. In 
fact, OSHA believes the best way to view this industry is as a series 
of incredibly well-funded start-up companies during the investment 
phase of the business, where short-term losses are expected and offset 
with the anticipation of enormous revenue growth potential (in an 
acknowledged very limited energy market.) Given these factors, OSHA's 
typical revenue and profit screen are a poor predictor of future 
viability with respect to this NAICS industry (although, as pointed 
out, this NAICS industry, like all other NAICS industries, falls well 
below the revenue screen threshold). The estimated cost of this ETS per 
firm is $866 in this NAICS industry, which equals about 11 cents per 
hundred dollars of revenue over a limited six-month duration. OSHA 
concludes that this industry will be able to withstand this small cost 
in order to keep its workers protected during the pandemic.
2. NAICS 488119--Other Airport Operations, 18.41 Percent 66
---------------------------------------------------------------------------

    \66\ This U.S. industry comprises establishments primarily 
engaged in (1) operating international, national, or regional 
airports, or public flying fields or (2) supporting airport 
operations, such as rental of hangar space, and providing baggage 
handling and/or cargo handling services.
---------------------------------------------------------------------------

    The services this industry offers are integrated into a particular 
geographic location and entail specific tasks, such as parking and 
baggage handling services, that must be done to ensure the proper 
functioning of airports, thus negating the potential for substitution 
during the 6 month period that OSHA is assuming the ETS will be in 
effect for economic purposes. In addition, because these are services 
that need to be done in particular domestic locations (i.e., airports), 
there is no risk of international competition.
3. NAICS 488410--Motor Vehicle Towing, 15.75 Percent 67
---------------------------------------------------------------------------

    \67\ This industry comprises establishments primarily engaged in 
towing light or heavy motor vehicles, both local and long-distance. 
These establishments may provide incidental services, such as 
storage and emergency road repair services.
---------------------------------------------------------------------------

    The actual cost impacts on this industry are likely significantly 
overstated to the extent that most employees performing towing services 
ride alone in their trucks and their services do not typically require 
exposure to others. In the event that individual large towing firms are 
concerned about economic impacts, it would not be difficult to 
structure their employee interactions with the company and customers to 
take advantage of the scope restrictions. Moreover, the primary 
services this industry offers involve the use of specialized vehicles 
designed uniquely for towing, thus lowering the risk of substitution. 
In addition, because these services are geographically based, there is 
no risk of international competition.
4. NAICS 488490--Other Support Activities for Road Transportation, 
14.32 Percent 68
---------------------------------------------------------------------------

    \68\ This industry comprises establishments primarily engaged in 
providing services (except motor vehicle towing) to road network 
users.
---------------------------------------------------------------------------

    This industry offers services that must be done to ensure proper 
operation of roadways (for example, bridge, tunnel, and highway 
operations, pilot car services (i.e., wide load warning services), 
driving services (e.g., automobile, truck delivery), and truck or 
weighing station operations), thus negating the potential for 
substitution. In addition, because these services need to be done in 
particular domestic locations (i.e., roadways), there is no risk of 
international competition.
5. NAICS 713920--Skiing Facilities, 13.16 Percent 69
---------------------------------------------------------------------------

    \69\ This industry comprises establishments engaged in (1) 
operating downhill, cross country, or related skiing areas and/or 
(2) operating equipment, such as ski lifts and tows. These 
establishments often provide food and beverage services, equipment 
rental services, and ski instruction services. Four season resorts 
without accommodations are included in this industry.
---------------------------------------------------------------------------

    This industry caters to a wealthy clientele who ensure an inelastic 
demand easily capable of absorbing any fractional increases 
attributable to this ETS.\70\ In addition, skiing is done outdoors, 
which will incentivize clientele to continue engaging in this 
particular activity in lieu of indoor substitutions, during the 
pandemic. Finally, there is little to no risk of international 
competition from foreign ski resorts because the added and substantial 
costs of international travel outweigh the costs associated with 
marginally higher prices resulting from the ETS.
---------------------------------------------------------------------------

    \70\ See Brown, January 19, 2017, ``[o]f the 9.4 million skiers 
in the U.S., more than half earn a salary higher than $100,000. For 
some context, only 20 percent of American households have a combined 
income of $100K. . . .'')
---------------------------------------------------------------------------

6. NAICS 713940--Fitness and Recreational Sports Centers, 12.33 Percent 
71
---------------------------------------------------------------------------

    \71\ This industry comprises establishments primarily engaged in 
operating fitness and recreational sports facilities featuring 
exercise and other active physical fitness conditioning or 
recreational sports activities, such as swimming, skating, or 
racquet sports.
---------------------------------------------------------------------------

    As these settings are generally located close to where clients live 
or work, there is no risk of international competition. Some of the 
largest employers in this industry have already responded to customer 
feedback by not only requiring employees to be vaccinated, but also


members.\72\ This suggests both that the costs estimates attributed to 
the ETS are overstated for these employers because higher levels of 
compliance may have already occurred than projected in OSHA's analysis, 
and that the ETS requirements reflect more of an industry trend than a 
threat to the existence of the industry.
---------------------------------------------------------------------------

    \72\ See Jackson, August 2, 2021 ``Equinox also noted in the 
press release that `an overwhelming majority of members' have 
expressed support for a vaccination requirement for entry to Equinox 
clubs.''
---------------------------------------------------------------------------

7. NAICS 713120--Amusement Arcades, 11.18 Percent 73
---------------------------------------------------------------------------

    \73\ This industry comprises establishments primarily engaged in 
operating amusement (except gambling, billiard, or pool) arcades and 
parlors.
---------------------------------------------------------------------------

    This industry caters to a select clientele who have chosen to 
engage in leisure activities in the unique settings offered by the 
industry, thus negating the likelihood for substitution. In addition, 
because these settings are localized, there is no risk of international 
competition.
8. NAICS 488320--Marine Cargo Handling, 10.03 Percent 74
---------------------------------------------------------------------------

    \74\ This industry comprises establishments primarily engaged in 
providing stevedoring and other marine cargo handling services 
(except warehousing).
---------------------------------------------------------------------------

    The services this industry offers are integrated into a particular 
location and entail specific tasks, such as loading and unloading 
services at ports and harbors, longshoremen services, marine cargo 
handling services, ship hold cleaning services, and stevedoring 
services, that must be done to ensure the proper movement of cargo off 
of and onto ships, thus negating the potential for substitution. In 
addition, because these are services that need to be done in particular 
domestic locations (e.g., docks), there is no risk of international 
competition.
    As with towing, the actual cost impacts on this industry are likely 
significantly overstated to the extent that some of the employees may 
be able to perform their work exclusively outdoors.
The Fourteen NAICS Industries With Negative Profit Ratios
1. Air Transportation 75
---------------------------------------------------------------------------

    \75\ NAICS 481111 (Scheduled Passenger Air Transportation) 
provides air transportation of passengers or passengers and freight 
over regular routes and on regular schedules, including commuter and 
helicopter carriers (except scenic and sightseeing). NAICS 481112 
(Scheduled Freight Air Transportation) provides air transportation 
of cargo without transporting passengers over regular routes and on 
regular schedules, including scheduled air transportation of mail on 
a contract basis. NAICS 481211 (Nonscheduled Chartered Passenger Air 
Transportation) provides air transportation of passengers or 
passengers and cargo with no regular routes and regular schedules. 
NAICS 481212 (Nonscheduled Chartered Freight Air Transportation) 
provides air transportation of cargo without transporting passengers 
with no regular routes and regular schedules. NAICS 481219 (Other 
Nonscheduled Air Transportation) provides air transportation with no 
regular routes and regular schedules (except nonscheduled chartered 
passenger and/or cargo air transportation). These establishments 
provide a variety of specialty air transportation or flying services 
based on individual customer needs using general purpose aircraft.
---------------------------------------------------------------------------

    NAICS 481111 (Scheduled Passenger Air Transportation), NAICS 481112 
(Scheduled Freight Air Transportation), NAICS 481211 (Nonscheduled 
Chartered Passenger Air Transportation), NAICS 481212 (Nonscheduled 
Chartered Freight Air Transportation), NAICS 481219 (Other Nonscheduled 
Air Transportation).
    This group of NAICS industries is comprised of U.S. industries that 
primarily engage in providing air transportation. There is little to no 
risk of substitution for this group of NAICS industries. Air 
transportation provides unique and important benefits that cannot be 
substituted via other forms of transportation (e.g., rail, freight, 
bus). (See ATAG, September 2005). To this end, air transportation is 
often the speediest means of transporting passengers and cargo, giving 
it a unique purpose that cannot be met by other forms of transport. It 
should be noted that the five NAICS in this group of industries are the 
only NAICS in NAICS 4811 (Scheduled Air Transportation) and 4812 
(Nonscheduled Air Transportation). The other industries in NAICS 48 
(Transportation) do not provide air transportation (See NAICS 
Association, 2018b). This further reduces the risk of substitution, as 
all five NAICS at issue have a negative profit ratio and therefore face 
similar challenges that appear to be endemic to air transportation. 
Firms in this industry that have been able to weather the pandemic this 
long are typically highly capitalized or have access to loans, so it is 
highly likely that they could also weather the temporary marginal costs 
of OSHA's ETS.
    There is also no risk of international competition with respect to 
this group of NAICS industries because any workers, whether they work 
for an international company or not, who are in the US, are subject to 
US laws, including the ETS, and foreign air carriers will need to 
follow the ETS for those workers. In addition, OSHA suspects that any 
smaller foreign air carriers will not have an incentive to expand their 
routes significantly or change their routes to domestic US routes to 
take advantage of the 100-employee cutoff in the ETS in the 6-months 
the ETS is assumed to be in effect.
2. Telecommunications 76
---------------------------------------------------------------------------

    \76\ NAICS 517311 (Wired Telecommunications Carriers) comprises 
establishments primarily engaged in operating and/or providing 
access to transmission facilities and infrastructure that they own 
and/or lease for the transmission of voice, data, text, sound, and 
video using wired telecommunications networks. Establishments in 
this industry use the wired telecommunications network facilities 
that they operate to provide a variety of services, such as wired 
telephony services, including VoIP services; wired (cable) audio and 
video programming distribution; wired broadband internet services; 
and, by exception, establishments providing satellite television 
distribution services using facilities and infrastructure that they 
operate are included in this industry. NAICS 517312 (Wireless 
Telecommunications Carriers (except Satellite)) comprises 
establishments primarily engaged in operating and maintaining 
switching and transmission facilities to provide communications via 
the airwaves. Establishments in this industry have spectrum licenses 
and provide services using that spectrum, such as cellular phone 
services, paging services, wireless internet access, and wireless 
video services. NAICS 517410 (Satellite Telecommunications) 
comprises establishments primarily engaged in providing 
telecommunications services to other establishments in the 
telecommunications and broadcasting industries by forwarding and 
receiving communications signals via a system of satellites or 
reselling satellite telecommunications. NAICS 517911 
(Telecommunications Resellers) comprises establishments engaged in 
purchasing access and network capacity from owners and operators of 
telecommunications networks and reselling wired and wireless 
telecommunications services (except satellite) to businesses and 
households. Establishments in this industry resell 
telecommunications; they do not operate transmission facilities and 
infrastructure. NAICS 517919 (All Other Telecommunications) 
comprises establishments primarily engaged in providing specialized 
telecommunications services, such as satellite tracking, 
communications telemetry, and radar station operation, and also 
includes establishments primarily engaged in providing satellite 
terminal stations and associated facilities connected with one or 
more terrestrial systems and capable of transmitting 
telecommunications to, and receiving telecommunications from, 
satellite systems, as well as establishments providing internet 
services or Voice over internet protocol (VoIP) services via client-
supplied telecommunications connections.
---------------------------------------------------------------------------

    NAICS 517311 (Wired Telecommunications Carriers), NAICS 517312 
(Wireless Telecommunications Carriers (except Satellite), NAICS 517410 
(Satellite Telecommunications), NAICS 517911 (Telecommunications 
Resellers), NAICS 517919 (All Other Telecommunications).
    This group of NAICS industries is entirely comprised of U.S. 
industries, except for NAICS 517410 (Satellite Telecommunications). All 
of these industries provide specialized unique services in the 
telecommunications industry that require specialized unique knowledge 
and are thus resistant to substitution. While it is perhaps


possible that different forms of telecommunications might be 
substituted for one another (e.g., the substitution of wired 
telecommunications carriers for wireless telecommunications carriers), 
the reality is that these different forms exist separately and feed 
different markets and customer needs that are independent of the ETS. 
Moreover, the five NAICS in this group of industries are the only NAICS 
in NAICS 5173 (Wired and Wireless Telecommunications Carriers), NAICS 
5174 (Satellite Telecommunications), and NAICS 5179 (Other 
Telecommunications). The other industries in NAICS 51 (Information) are 
not engaged in telecommunications (NAICS Association, 2018c). This 
further reduces the risk of one industry substituting for the others, 
as all five NAICS at issue have a negative profit ratio and therefore 
face similar challenges that appear to be endemic to 
telecommunications.
    Moreover, three of the five NAICS industries in this group (NAICS 
517311, 517312, 517410) operate or control the infrastructure needed 
for engaging in the particular type of telecommunications in which 
those industries engage. This not only fully negates the risk of 
substitution, but also negates the risk of international competition 
for these industries.
    The other two industries in the group apparently do not operate or 
control the infrastructure needed for telecommunications. However, the 
telecommunications industry faces strict state and federal licensing 
requirements, which severely limit the risk of competition both 
internationally and from smaller firms seeking to take advantage of the 
ETS's 100-employee cutoff. (See FCC, 2014; FCC, October 12, 2021a; FCC, 
October 12, 2021b; Caltrans, October 12, 2021; and UTC, October 12, 
2021).
3. Car and Equipment Rental 77
---------------------------------------------------------------------------

    \77\ NAICS 532111 (Passenger Car Rental) comprises 
establishments primarily engaged in renting passenger cars without 
drivers, generally for short periods of time. NAICS 532112 
(Passenger Car Leasing) comprises establishments primarily engaged 
in leasing passenger cars without drivers, generally for long 
periods of time. NAICS 532120 (Truck, Utility Trailer, and RV 
(Recreational Vehicle) Rental and Leasing comprises establishments 
primarily engaged in renting or leasing, without drivers, one or 
more of the following: Trucks, truck tractors, buses, semi-trailers, 
utility trailers, or RVs (recreational vehicles). NAICS 532310 
(General Rental Centers) comprises establishments primarily engaged 
in renting a range of consumer, commercial, and industrial 
equipment. Establishments in this industry typically operate from 
conveniently located facilities where they maintain inventories of 
goods and equipment that they rent for short periods of time. The 
type of equipment that establishments in this industry provide often 
includes, but is not limited to: Audio visual equipment, 
contractors' and builders' tools and equipment, home repair tools, 
lawn and garden equipment, moving equipment and supplies, and party 
and banquet equipment and supplies.
---------------------------------------------------------------------------

    NAICS 532111 (Passenger Car Rental), NAICS 532112 (Passenger Car 
Leasing), NAICS 532120 (Truck, Utility Trailer), and RV (Recreational 
Vehicle) Rental and Leasing) NAICS 532310 (General Rental Centers).
    This group of industries rent motor vehicles (NAICS 532111, 532112, 
532120) or equipment (NAICS 532310), for example, audio visual 
equipment, contractors' and builders' tools and equipment, home repair 
tools, lawn and garden equipment, moving equipment and supplies, and 
party and banquet equipment and supplies, to individuals and 
businesses, for personal and professional use. There is no risk of 
substitution with respect to these industries, as these industries rent 
specific items to those who want to use them. There is also no risk of 
foreign competition with respect to these industries, as consumers and 
businesses rent and pick up vehicles, as well as the type of equipment 
offered for rent by NAICS 532310, from specific locations, including 
car rental and other rental centers.
    These industries have not been hard hit by the pandemic, as many 
consumers have turned from group travel to individual transportation. 
For example, RV rentals and leasing has soared during the pandemic, 
which is not reflected in the pre-pandemic profit and revenue data 
available for this analysis.\78\

V. Additional Requirements

A. Regulatory Flexibility Act

    Whenever an agency is required by the Administrative Procedure Act, 
5 U.S.C. 553, or another law, to publish a general notice of proposed 
rulemaking, the Regulatory Flexibility Act (RFA), 5 U.S.C. 601 et seq., 
requires the agency to prepare an initial regulatory flexibility 
analysis (IRFA). 5 U.S.C. 601(2), 603(a). Since this ETS ``shall serve 
as a proposed rule'' for a final standard under section 6(c)(3) of the 
OSH Act, it is treated as a general notice of proposed rulemaking under 
the RFA. An agency may waive or defer the IRFA in the event a rule is 
promulgated in response to an emergency that makes compliance with the 
requirements of section 603 impracticable. 5 U.S.C. 608(a). The agency 
hereby certifies that compliance with the IRFA requirement is 
impracticable under the circumstances. OSHA prepared this ETS on an 
expedited basis in response to a national emergency affecting the lives 
and health of the nation's workers; the IRFA is inherently a relatively 
lengthy process that would be impracticable to undertake for a standard 
of such broad applicability in the limited time available. Because OSHA 
is not preparing an IRFA for the ETS, the agency is also not required 
to convene a small entity panel under section 609(b).

B. Unfunded Mandates Reform Act (UMRA), 2 U.S.C. 1501 et seq.

    Section 202 of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 
U.S.C. 1532, requires agencies to assess the anticipated costs and 
benefits of a rule before issuing ``any general notice of proposed 
rulemaking'' that includes a Federal mandate that may result in 
expenditures in any one year by state, local, or Tribal governments, or 
by the private sector, of at least $100 million, adjusted annually for 
inflation. The assessment requirement also applies to ``any final rule 
for which a general notice of proposed rulemaking was published.'' 
Although no general notice of proposed rulemaking was published, the 
agency has analyzed the ETS's economic feasibility and health impacts 
in Section IV.B. of this preamble (Economic Analysis) and Health 
Impacts Appendix (OSHA, October 2021c).

C. Executive Order 13175

    Section 5 of E.O. 13175, on Consultation and Coordination with 
Indian Tribal Governments, requires agencies to consult with tribal 
officials early in the process of developing regulations that: (1) Have 
tribal implications, that impose substantial direct compliance costs on 
Indian governments, and that are not required by statute; or (2) have 
tribal implications and preempt tribal law. 65 FR 67249, 67250 (Nov. 6, 
2000). E.O. 13175 requires that such consultation occur to the extent 
practicable. Given the expedited nature of issuing the ETS, it was not 
practicable for OSHA to consult and incorporate non-federal input prior 
to promulgation of the standard. OSHA commits to meaningful 
consultation with tribal representatives after publication of the ETS 
and during the comment period before finalizing any permanent standard. 
Such consultation will be consistent with the Administrative Procedure 
Act.

D. National Environmental Policy Act

    OSHA has reviewed this ETS according to the National Environmental 
Policy Act (NEPA) of 1969, 42 U.S.C. 4321 et seq., the regulations of 
the Council on Environmental Quality, 40 CFR chapter V, subchapter A, 
and the Department of Labor's NEPA procedures, 29 CFR part 11. As a 
result of this review, the agency has determined that the rule will 
have no significant impact on air, water, or soil quality; plant or 
animal life; the use of land; or other aspects of the external 
environment. Although the ETS contains testing requirements, and test 
kits and supplies can generate some additional materials that will 
enter the waste stream, the impact of this ETS will be minimal. As 
discussed in more detail in Technological Feasibility (Section IV.A. of 
this preamble), there is already a surplus of available tests, and 
projected production of COVID-19 tests will be more than sufficient to 
meet demands for testing created as a result of the rule. Therefore, 
tests used for purposes of or for compliance with this ETS are not 
being produced as a result of this standard, and the standard will not 
generate significant new streams of waste beyond what would be 
generated in the absence of the standard.

E. Congressional Review Act

    This ETS is considered a major rule under the Congressional Review 
Act (CRA), 5 U.S.C. 801 et seq. Section 801(a)(3) of the CRA normally 
requires a 60-day delay in the effective date of a major rule. 5 U.S.C. 
801(a)(3), 804(2). However, section 808(2) of the CRA allows the 
issuing agency to make a rule effective sooner than otherwise provided 
by the CRA if the agency makes a good cause finding that notice and 
public procedure are impracticable, unnecessary, or contrary to the 
public interest. 5 U.S.C. 808(2). OSHA finds that there is good cause 
to make this rule effective upon publication because notice and public 
procedure with respect to this ETS are both impracticable and contrary 
to the public interest, given the expedited timeline on which this 
standard was developed and the grave danger threatening workers' lives 
and health (see Grave Danger and Need for the ETS, both in Section III. 
of this preamble). Congress authorized OSHA to take swift action in 
promulgating an ETS to address this type of grave danger, and provided 
explicitly that an ETS is effective upon publication, 29 U.S.C. 
655(c)(1); delaying the effective date of such an expedited process 
would thwart that purpose. It is specifically because of the emergency 
nature of this rulemaking that the OSH Act allows for OSHA to proceed 
without the extensive public input the agency normally solicits in 
issuing occupational safety and health standards. 29 U.S.C. 655(c)(1). 
For rules to which section 808(2) applies, the agency may set the 
effective date. In this case, consistent with the OSH Act requirement 
cited above, the ETS takes immediate effect upon publication in the 
Federal Register.

F. Administrative Procedure Act

    The Administrative Procedure Act (APA) normally requires notice and 
comment, and a 30-day delay of the effective date of a final rule, for 
recordkeeping and reporting regulations promulgated under section 8(c) 
of the OSH Act. 29 U.S.C. 657(c); 5 U.S.C. 553(b), (d). This ETS 
contains recordkeeping and reporting requirements tailored to address 
COVID-19 illness. To the extent that these requirements are not already


exempt from the APA's requirements for notice and comment under section 
6(c) of the Act (29 U.S.C. 655(c)), OSHA invokes the ``good cause'' 
exemption to the APA's notice requirement because the agency finds that 
notice and public procedure are impracticable and contrary to the 
public interest under 5 U.S.C. 553(b)(B). As explained in more detail 
in Grave Danger and Need for the ETS (both in Section III. of this 
preamble), this finding is based on the critical importance of 
implementing the requirements in this ETS, including the recordkeeping 
and reporting provisions, as soon as possible to address the grave 
danger that COVID-19 presents to workers.
    As noted above, the ETS is required by the OSH Act to take 
immediate effect upon publication. 29 U.S.C. 655(c)(1). For that 
reason, and the underlying public health emergency that prompted this 
ETS as discussed above, OSHA finds good cause to waive the normal 30-
day delay in the effective date of a final rule from the date of its 
publication in the Federal Register. See 5 U.S.C. 553(d)(3). OSHA 
notes, however, that OSHA does not require compliance with any 
provision of the ETS within the first 30 days after it becomes 
effective.

G. Consensus Standards

    OSHA must consider adopting an existing national consensus standard 
that differs substantially from OSHA's standard if the consensus 
standard would better effectuate the purposes of the Act. See section 
12(d)(1) of the National Technology Transfer and Advancement Act of 
1995 (15 U.S.C.A. 272 Note); see also 29 U.S.C. 655(b)(8).
    OSHA considered incorporation of ASTM F3502-21 in this ETS, as 
required. However, the agency has insufficient evidence to make a 
general finding of feasibility at this time. The agency notes that face 
coverings that meet ASTM F3502-21 criteria also meet the definition of 
``face coverings'' in this ETS (see the discussion of this issue in 
Summary and Explanation, Section VI. of this preamble). The agency has 
asked questions about this topic to gather additional information.

H. Executive Order 13045

    Executive Order 13045, on Protection of Children from Environmental 
Health Risks and Safety Risks, requires that Federal agencies 
submitting covered regulatory actions to OIRA for review pursuant to 
Executive Order 12866 must provide OIRA with (1) an evaluation of the 
environmental health or safety effects that the planned regulation may 
have on children, and (2) an explanation of why the planned regulation 
is preferable to other potentially effective and reasonably feasible 
alternatives considered by the agency (62 FR 19885 (April 23, 1997)). 
Executive Order 13045 defines ``covered regulatory actions'' as rules 
that may (1) be economically significant under Executive Order 12866, 
and (2) concern an environmental health risk or safety risk that an 
agency has reason to believe may disproportionately affect children. 
Because OSHA has no reason to believe that the risk from COVID-19 
disproportionately affects children, the ETS is not a covered 
regulatory action and OSHA is not required to provide OIRA with further 
analysis under section 5 of the executive order. However, to the extent 
children are exposed to COVID-19 either as employees or at home as a 
result of family members' workplace exposures to COVID-19, the ETS 
should provide some protection for children.

I. Federalism

    The agency reviewed this ETS according to Executive Order 13132, on 
Federalism, which requires that Federal agencies, to the extent 
possible, refrain from limiting State policy options, consult with 
States before taking actions that would restrict States' policy 
options, and take such actions only when clear constitutional authority 
exists and the problem is of national scope. 64 FR 43255 (August 10, 
1999). The Executive Order generally allows Federal agencies to preempt 
State law only as provided by Congress or where State law conflicts 
with Federal law. In such cases, Federal agencies must limit preemption 
of State law to the extent possible.
    The Occupational Safety and Health Act is an exercise of Congress's 
Commerce Clause authority, and under Section 18 of the Act, 29 U.S.C. 
667, Congress expressly provided that States may adopt, with Federal 
approval, a plan for the development and enforcement of occupational 
safety and health standards. OSHA refers to States that obtain Federal 
approval for such plans as ``State Plans.'' Occupational safety and 
health standards developed by State Plans must be at least as effective 
in providing safe and healthful employment and places of employment as 
the Federal standards. As discussed below, State Plans must submit to 
Federal OSHA for approval, standards that differ from Federal standards 
addressing the same issues, in order for such standards to become part 
of the OSHA-approved State Plan. Subject to these requirements, State 
Plans are free to develop and enforce their own occupational safety and 
health standards.
    This ETS complies with E.O. 13132. The problems addressed by this 
ETS for COVID-19 are national in scope. As explained in Grave Danger 
(Section III.A. of this preamble), employees face a grave danger from 
exposure to COVID-19 in the workplace. Employees across the country 
face the danger of exposure to COVID-19 at work, and as explained in 
Need for the ETS (Section III.B. of this preamble), a national standard 
is needed to protect workers from the grave danger of COVID-19 by 
strongly encouraging vaccination and limiting the presence of COVID-19 
positive workers in the workplace through testing and to ensure that a 
clear and consistent baseline approach is taken across the country to 
protect them. The SARS-CoV-2 virus is highly communicable and infects 
workers without regard to state borders, making a national approach 
necessary. Accordingly, the ETS establishes minimum requirements for 
employers in every State to protect employees from the risks of 
exposure to COVID-19.
    In States without OSHA-approved State Plans, Congress provides for 
OSHA standards to preempt State occupational safety and health 
standards for issues addressed by the Federal standards. In these 
States, this ETS limits State policy options in the same manner as 
every standard promulgated by the agency. Furthermore, as discussed in 
the Summary and Explanation for Purpose, nothing in the ETS is intended 
to limit generally applicable public health measures instituted by 
state or local governments that go beyond, and are not inconsistent 
with, the requirements of the ETS. (See Summary and Explanation for 
Purpose, Section VI.A. of this preamble); Gade v. National Solid Wastes 
Management Ass'n, 505 U.S. 88, 107 (1992). In States with OSHA-approved 
State Plans, this ETS does not significantly limit State policy 
options. Any special workplace problems or conditions in a State with 
an OSHA-approved State Plan may be dealt with by that State's standard, 
provided the standard is at least as effective as this ETS.
    As discussed in the Summary and Explanation for Purpose in this 
preamble, OSHA has included a provision that states the purpose of this 
ETS, as well as OSHA's intent to preempt all inconsistent State and 
local requirements that relate to the issues addressed by this ETS. 
(See section 1910.501(a); Summary and Explanation for Purpose, Section 
VI.A. of this preamble). This includes State and local


requirements banning or limiting the authority of employers to require 
vaccination, face covering, or testing. As discussed in that section, 
such State and local bans would be preempted by this ETS, even in 
States with OSHA-approved State Plans, because such bans are not 
approved by federal OSHA as part of the State Plan and could not be 
approved, because such bans are clearly not as effective--and, indeed, 
are contrary to--the federal ETS. See Indust. Truck Ass'n v. Henry, 125 
F.3d 1305, 1311 (9th Cir. 1997).

J. State Plans

    When Federal OSHA promulgates an emergency temporary standard, 
States and U.S. Territories with their own OSHA-approved occupational 
safety and health plans (``State Plans'') must either amend their 
standards to be identical or ``at least as effective as'' the new 
standard, or show that an existing State Plan standard covering this 
area is ``at least as effective'' as the new Federal standard. 29 CFR 
1953.5(b). This ETS imposes new requirements to protect workers across 
the nation from COVID-19. Adoption of this ETS, or an ETS that is at 
least as effective as this ETS, by State Plans must be completed within 
30 days of the promulgation date of the final Federal rule, and State 
Plans must notify Federal OSHA of the action they will take within 15 
days. The State Plan standard must remain in effect for the duration of 
the Federal ETS. As noted above in Federalism (Section V.I. of this 
preamble), this ETS preempts all State and local requirements, 
including in States with State Plans, that ban or limit the authority 
of employers to require vaccination, face covering, or testing. (See 
also the Summary and Explanation for Purpose, Section VI.A. of this 
preamble). As with all non-identical State Plan standards, OSHA will 
review any comparable State standards to determine whether they are at 
least as effective as this ETS. A State Plan standard that prohibits 
employers from requiring vaccination would not be at least as effective 
as this ETS because OSHA has recognized in this ETS that vaccination is 
the most protective policy choice for employers to adopt to protect 
their workplaces.
    Of the 28 States and Territories with OSHA-approved State Plans, 22 
cover both public and private-sector employees: Alaska, Arizona, 
California, Hawaii, Indiana, Iowa, Kentucky, Maryland, Michigan, 
Minnesota, Nevada, New Mexico, North Carolina, Oregon, Puerto Rico, 
South Carolina, Tennessee, Utah, Vermont, Virginia, Washington, and 
Wyoming. The remaining six States and Territories cover only state and 
local government employees: Connecticut, Illinois, Maine, New Jersey, 
New York, and the Virgin Islands.

K. Paperwork Reduction Act

I. Overview
    The Emergency Temporary Standard (ETS) for COVID-19 Vaccination and 
Testing contains collection of information requirements that are 
subject to review by the Office of Management and Budget (OMB) under 
the Paperwork Reduction Act of 1995 (PRA), 44 U.S.C. 3501, et seq., and 
OMB's regulations at 5 CFR part 1320. The PRA defines a collection of 
information to mean the obtaining, causing to be obtained, soliciting, 
or requiring the disclosure to third parties or the public, of facts or 
opinions by or for an agency, regardless of form or format (44 U.S.C. 
3502(3)(A)). OSHA has determined an ETS is necessary to protect workers 
from the grave danger posed by COVID-19 and is issuing an ETS that 
amends 29 CFR 1910 subpart U to provide COVID-19 protections to workers 
of employers with 100 or more employees. Section 1910.501 contains 
collections of information necessary to effectuate the purpose of the 
ETS. The collections of information appear in paragraphs 1910.501(d), 
(e)(2), (e)(4), (f)(1), (g)(1), (g)(4), (h)(1), (j), (k)(1), (k)(2), 
(l)(1), and (l)(2). For a more comprehensive discussion of these 
provisions, see the sectional analysis earlier in this preamble. These 
information collections are applied by cross reference to other 
industries in regulations 29 CFR 1915.1501 (Shipyard Employment), 
1917.31 (Marine Terminals), 1918.110 (Longshoring), 1926.58 
(Construction), 1928.21 (Agriculture).\79\
---------------------------------------------------------------------------

    \79\ The ETS applies to agricultural establishments with 11 or 
more employees engaged on any day in hand-labor occupations in the 
field and agricultural establishments that maintain a temporary 
labor camp, regardless of how many employees are engaged on any day 
in hand-labor occupations in the field).
---------------------------------------------------------------------------

    Under the PRA, a Federal agency cannot conduct or sponsor a 
collection of information unless OMB approves it and the agency 
displays a currently valid OMB control number (44 U.S.C. 3507). 
Notwithstanding any other provision of law, if a collection of 
information does not display a currently valid control number, an 
employer shall not be subject to penalty for failing to comply with the 
collection of information (44 U.S.C. 3512). The PRA has special 
provisions for emergency situations that are applicable to this ETS. 
OMB may authorize a collection of information without regard to the 
normal clearance procedures if either (a) the relevant agency 
determines that the collection of information is essential to the 
mission of the agency and public harm is reasonably likely to result if 
normal clearance procedures are followed, or (b) the use of normal 
clearance procedures is reasonably likely to cause a statutory or court 
ordered deadline to be missed (44 U.S.C. 3507(j) and 5 CFR 1320.13). 
Because COVID-19 presents an ongoing public health threat to workers 
and American businesses, OSHA has requested the use of these emergency 
procedures for this ETS. In accordance with 44 U.S.C. 3507(j)(1), OMB 
approved the request and assigned this ETS an OMB control number that 
is valid for 180 days. Therefore, the information collection provisions 
contained within this ETS will take effect at the same time as all 
other provisions.
II. Summary of Information Collection Requirements
    This information collection is summarized as follows.
    1. Title: COVID-19 Vaccination and Testing Emergency Temporary 
Standard (29 CFR 1910, subpart U; 1915, subpart Z; 1917, subpart B; 
1918, subpart K; 1926, subpart D; 1928, subpart B).
    2. Type of Review: Emergency.
    3. OMB Control Number: 1218-0278.
    4. Affected Public: This rule applies to employers with a total of 
100 or more employees except where the workplace is covered under the 
Safer Federal Workforce Task Force COVID-19 Workplace Safety: Guidance 
for Federal Contractors and Subcontractors; or in setting where the 
employee provides healthcare services or healthcare support services 
that falls under the requirements of 29 CFR 1910.502. This rule does 
not apply to employees of covered employers who work from home, 
exclusively outdoors, or who do not report to a workplace where other 
individuals such as coworkers or customers are present.
    5. Description of the ICR. This ICR contains collections of 
information requirements for employers with 100 or more employees. The 
employer must establish, implement, and enforce a written mandatory 
vaccination policy that requires each employee to be fully vaccinated 
against COVID-19 unless the employer implements a policy that allows 
employees to choose between being fully vaccinated or both tested and 
wearing a face covering. Employers must determine employee vaccination 
status, and must require than any employees who are not vaccinated be 
tested for COVID-19 at least once every


7 days. Employers must provide specified information to employees 
regarding COVID-19 vaccine efficacy, safety, and the benefits of being 
vaccinated, and must maintain a record of the COVID-19 vaccination 
status, proof of vaccination, and copies of employee COVID-19 test 
results, and the aggregate number of fully vaccinated employees at a 
workplace along with the total number of employees at that workplace.
    6. Number of respondents: 1,858,935.
    7. Frequency: Varies.
    8. Number of Responses: 205,262,803.
    9. Estimated Burden Hours: 79,720,444.
    10. Estimated Cost (Capital-operation and maintenance): 
$1,383,751,520.
    These totals are explained and supported in the agency's Supporting 
Statement as required by the PRA.
III. Request for Comment
    Although the ETS takes effect immediately, with implementation 
dates specified in the Dates provision of this publication, it also 
serves as a temporary standard that can only be made permanent 
following an opportunity for public notice and comment. OSHA therefore 
invites the public to submit comments to OSHA on the proposed 
collections of information with regard to the following.
     Whether the proposed collections of information are 
necessary for the proper performance of the Agency's functions, 
including whether the information is useful.
     The accuracy of OSHA's estimate of the burden (time and 
cost) of the collections of information, including the validity of the 
methodology and assumptions used.
     The quality, utility, and clarity of the information 
collected.
     Ways to minimize the compliance burden on employers, for 
example, by using automated or other technological techniques for 
collecting and transmitting information.
    Please submit comments related to the Paperwork Act analysis to 
OSHA in the PRA docket (Docket Number OSHA-2021-0008). Comments related 
to other parts of the ETS should be submitted to the rulemaking docket 
(Docket Number OSHA-2021-0007). OSHA will accept comments for 60 days 
on the information collection aspects of the rule. For instructions on 
submitting these comments to the rulemaking and/or PRA docket, see the 
sections of this Federal Register notice titled DATES and ADDRESSES.

ETS. (OSHA, October 2021c)

VI. Summary and Explanation

A. Purpose

    The ETS includes a sentence that states the purpose of the rule. 
The first part of the sentence in the paragraph indicates that the 
standard addresses the grave danger of COVID-19 in the workplace by 
establishing workplace vaccination, vaccination verification, face 
covering and testing requirements.
    The second part of the sentence addresses the preemption of State 
and local laws, regulations, executive orders, and other requirements, 
by this Federal standard. It indicates OSHA's intention that the ETS 
address comprehensively the occupational safety and health issues of 
vaccination, wearing face coverings, and testing for COVID-19, and thus 
that the standard is intended to preempt States, and political 
subdivisions of States, from adopting and enforcing workplace 
requirements relating to these issues, except under the authority of a 
Federally-approved State Plan. In particular, OSHA intends to preempt 
any State or local requirements that ban or limit an employer's 
authority to require vaccination, face covering, or testing.
    Preemption of such State and local requirements derives from 
section 18 of OSH Act and general principles of conflict preemption. 
See Gade v. National Solid Wastes Management Ass'n, 505 U.S. 88 
(1992).\80\ Gade clarified two important principles. First, section 18 
expresses Congress' intent to preempt State workplace safety or health 
laws relating to issues on which Federal OSHA has promulgated 
occupational safety and health standards. Under section 18, a State can 
avoid preemption of such laws only if it submits and receives Federal 
approval for a State Plan for the development and enforcement of 
standards. OSHA-approved State Plans operate under authority of State 
law and must adopt occupational safety and health standards which, 
among other things, must be at least as effective in providing safe and 
healthful employment and places of employment as Federal standards. 29 
U.S.C. 667.
---------------------------------------------------------------------------

    \80\ The Court held that the dual impact licensing statutes were 
preempted; however, no rationale commanded a majority. A four-
justice plurality found that supplementary State regulation is 
impliedly preempted. Id. at 98-99. Justice Kennedy's concurrence 
would have found express preemption rather than implied preemption, 
Id. at 110-111, but otherwise agreed that ``in the OSH statute 
Congress intended to pre-empt supplementary state regulation.'' Id. 
at 113.
---------------------------------------------------------------------------

    Second, State and local laws that do not constitute occupational 
safety or health laws because they are ``laws of general 
applicability'' that regulate workers and nonworkers alike are 
preempted only if they conflict with the federal standard. Laws of 
general applicability that are consistent with the federal standard are 
not preempted. Gade, 505 U.S. at 107.
    While section 18 applies to every occupational safety and health 
standard that OSHA promulgates, this ETS raises particular concerns 
because of the current landscape of existing State and local 
requirements that may overlap with, or directly conflict with, the 
requirements of this ETS. As discussed in Need for the ETS (Section 
III.B. of this preamble), OSHA is adopting this ETS in response to an 
unprecedented health crisis that has resulted in a global pandemic 
severely impacting the health and wellbeing of people in the United 
States, and globally. This ETS is issued based on OSHA's determination 
that employees in the United States face a grave danger from workplace 
exposures to SARS-CoV-2, that the ETS is necessary to protect those 
workers, and that the measures for vaccination, vaccine verification, 
face coverings, and testing that this ETS requires will help ensure 
that workers covered by the ETS are protected from severe illness and 
death resulting from contracting COVID-19 in the workplace.
    As explained in Need for the ETS (Section III.B. of this preamble), 
the lack of a national standard on this hazard has led to disparate 
State and local requirements, and this underscores the need for OSHA's 
ETS to provide clear and consistent protection to employees across the 
country. Over the past months, an increasing number of States have 
passed laws or enacted other requirements banning workplace vaccination 
policies that would mandate vaccination or require proof of vaccination 
status, thus prohibiting employers operating in those jurisdictions 
from implementing this proven method of protecting workers from the 
hazard of COVID-19 that is at the core of this ETS (see, e.g., Texas 
Executive Order GA-40, October 11, 2021; Montana H.B. 702, July 1, 
2021; Arkansas S.B. 739, October 4, 2021 and Arkansas H.B. 1977, 
October 1, 2021; AZ Executive Order 2021-18, Aug. 16, 2021). While some 
States' bans have focused on preventing local governments from 
requiring their public employees to be vaccinated or show proof of 
vaccination, the Texas, Montana, and Arkansas requirements apply to 
private employers as well. Likewise, some States and localities


have enacted requirements that prohibit businesses, government offices, 
schools or other public spaces from requiring that face coverings be 
worn (see, e.g., Florida Executive Order 21-102, May 3, 2021; Texas 
Executive Order GA-34, March 2, 2021; Texas Executive Order GA-36, May 
18, 2021). State and local requirements that prohibit employers from 
implementing employee vaccination mandates, or from requiring face 
coverings in workplaces, serve as a barrier to OSHA's implementation of 
this ETS, and to the protection of America's workforce from this deadly 
virus.
    As discussed below, state restrictions of this kind are clearly 
preempted whether they take the form of direct workplace regulation or 
are part of a law of general applicability because they relate to the 
issues addressed by this standard and conflict with it. Gade, 505 U.S. 
at 99, 107. As is also discussed below, this is true even for State or 
local requirements that may not prevent employers from compliance with 
the ETS, but that prescribe or limit the employer's ability to mandate 
vaccination for its workforce as the employer's chosen means of 
compliance. See Gade, 505 at 107; see also Geier v. American Honda, 529 
U.S. 861, 869, 875-886 (2000) (finding Department of Transportation 
(DOT) regulations preempted a State tort action where the state action 
``upset the careful regulatory scheme established by federal law'' and 
placing weight on DOT's interpretation that such tort suit would be 
``an obstacle to the accomplishment and execution'' of Agency 
objectives). An employer's choice to mandate vaccination is a critical 
aspect of this ETS, and state laws that remove that choice conflict 
with it.
    Thus, to ensure that the ETS supplants the existing State and local 
vaccination bans and other requirements that could undercut its 
effectiveness, and to foreclose the possibility of future bans, OSHA 
has clearly defined the issues addressed by this section to encompass 
vaccination, face covering, and testing needed to protect against 
transmission of COVID-19 to employees in the workplace. To avoid 
ambiguity, OSHA has stated expressly that it intends this ETS to 
preempt all State and local workplace requirements that ``relate'' to 
these issues, except pursuant to a State Plan. 29 U.S.C. 667(b).
    The ``unavoidable implication'' of section 18 is that because OSHA 
has adopted this ETS, States may no longer regulate these issues except 
with OSHA's approval and the authority of a Federally-approved State 
Plan. Gade, 505 U.S. at 99. As the Court explained, section 18 preempts 
States without approved plans from adopting or enforcing any laws that 
constitute, ``in a direct, clear and substantial way regulation of 
worker health and safety'' relating to an issue addressed by an OSHA 
standard. Id. at 107.
    State and local requirements that ban or otherwise limit workplace 
vaccination, face covering, or testing clearly ``relate'' to the 
occupational safety and health ``issues'' that OSHA is regulating in 
this ETS. 29 U.S.C. 667(b). Such bans regulate key workplace COVID-19 
protections that are encompassed by this ETS ``in a direct, clear and 
substantial way.'' Gade, 505 U.S. at 107. The direct effect of such 
bans is to prohibit employers from requiring employees to implement 
measures, such as vaccination requirements, face coverings, or testing. 
These workplace protective measures are covered by, and, in many 
circumstances required by, this ETS. For example, vaccination mandate 
bans directed at employers specifically bar them from requiring 
employee vaccination requirements for the purposes of protecting their 
workforce. Prohibitions on face covering mandates likewise directly 
prohibit individuals in positions of authority, including employers, 
from requiring face covering use.
    Although the expressly stated purposes for State and local 
requirements banning or limiting employers from requiring vaccinations, 
face coverings, or testing may not be occupational safety and 
health,\81\ this does not control their preemption under section 18 of 
the OSH Act. In assessing State and local requirements' impact on a 
federal statutory scheme, courts ``have refused to rely solely on the 
legislature's professed purpose and have looked as well to the effects 
of the law.'' Gade, 505 U.S. at 105; see also, e.g., Perez v. Campbell, 
402 U. S. 637, 651-652 (1971) (``[A]ny state legislation which 
frustrates the full effectiveness of federal law is rendered invalid by 
the Supremacy Clause''); Napier v. Atlantic Coast Line R. Co., 272 U.S. 
605, 612 (1926) (pre-emption analysis does not depend on whether 
federal and State laws ``are aimed at distinct and different evils'' 
but whether they ``operate upon the same object'').
---------------------------------------------------------------------------

    \81\ The express purposes of such requirements banning or 
limiting employers from requiring vaccination, face coverings, or 
testing may often not relate to occupational safety and health. For 
example, Governor Greg Abbott's Texas face covering mandate ban in 
Executive Order GA-16, is based on alleged decreasing COVID-19 rates 
and the need to alleviate ``confusion,'' (Texas Executive Order GA-
36, May 18, 2021); the stated purpose of Montana's vaccination 
mandate ban is to address health care privacy interests (Montana 
H.B. 702, July 1, 2021).
---------------------------------------------------------------------------

    That a State has articulated a purpose other than, or in addition 
to, workplace health and safety would not divest the OSH Act of its 
preemptive force, because preemption law looks to the effects as well 
as the purpose of a State law, and thus a dual-impact State law cannot 
avoid OSH Act preemption simply because the regulation serves several 
objectives. Gade, 505 U.S. at 107 (holding ``a law directed at 
workplace safety is not saved from pre-emption simply because the State 
can demonstrate some additional effect outside of the workplace'' and 
``[t]hat such law may also have a nonoccupational impact does not 
render it any less of an occupational standard for purposes of pre-
emption analysis''). Thus, to the extent that the stated purpose of a 
requirement that bans or limits employers from requiring vaccinations, 
face coverings, or testing is something other than, or in addition to, 
occupational health, such laws, which have a specific and direct impact 
on worker health, are nevertheless preempted.
    Further, section 18 preempts even ``nonconflicting'' State and 
local occupational safety and health requirements relating to the 
issues addressed by this standard. Gade, 505 U.S. at 98-99, 103; see 
id. at 100 (``state laws regulating the same issue as federal laws are 
not saved, even if they merely supplement the federal standard''). This 
is because OSHA ``'pre-empts the field' for any nonapproved State law 
regulating the same safety and health issue.'' See Gade, 505 U.S. at 
104, n. 2, citing English v. General Electric. Co., 496 U.S. 72, 79-80, 
n.5 (``[F]ield preemption may be understood as a species of conflict 
pre-emption: A State law that falls within a pre-empted field conflicts 
with Congress' intent (either express or plainly implied) to exclude 
state regulation''); see also id. at 105 (discussing effect of field 
preemption). See generally Geier, 529 U.S. at 869, 875-886 (finding 
State law preemption where it ``upset the careful regulatory scheme 
established by federal law''); Williamson v. Mazda Motor of Am., Inc., 
562 U.S. 323, 330-36 (2011) (affirming the conflict pre-emption 
principle that ``a state law that stands as an obstacle to the 
accomplishment and execution of the full purposes and objectives of a 
federal law is pre-empted'' and finding preemption where State law 
interfered with ``significant objective'' of the federal regulation).
    For example, the ETS would preempt State or local governments from


dictating that employers adopt a scheme of testing and face coverings 
that complies with 1910.501(g) and (i) of the ETS, but that bars 
employers from electing the preferred vaccine mandate alternative in 
paragraph (d), because this interferes with OSHA's significant 
regulatory objectives and its preemption of the field.\82\ (See Need 
for the ETS (Section III.B. of this preamble) discussing that 
vaccination is the preferred compliance option under this rule because 
it is the most effective method of protecting workers from COVID-19). 
Likewise, the ETS would preempt such State or local occupational 
requirements, even to the extent that they may regulate employers with 
fewer than 100 employees, notwithstanding that the requirements in this 
ETS only apply to employers with more than 100 employees.
---------------------------------------------------------------------------

    \82\ OSHA is aware that some States have adopted or are 
considering adopting such requirements, which this ETS would preempt 
(see, e.g., Arkansas S.B. 739, October 4, 2021 and Arkansas H.B. 
1977, October 1, 2021, which Arkansas Governor Asa Hutchinson 
allowed to became law without his signature, and which require 
employers in Arkansas to allow employees to opt out of vaccination 
for purposes of complying with federal vaccination requirements; see 
also Governor Hutchinson, October 13, 2021; Marr, October 7, 2021 
(describing the Arkansas legislation and noting that other states 
may contemplate similar legislation)).
---------------------------------------------------------------------------

    Case law is instructive on this point. In Gade, the Supreme Court 
found regulations implementing a State statute that required training 
for workers handling hazardous waste that went beyond, but did not 
conflict with, OSHA's hazardous waste training requirements to be 
preempted by the OSHA requirements. Id. Likewise, in Industrial Truck 
Association Incorporated v. Henry, the Ninth Circuit found that OSHA's 
hazard communication standard preempted California's Hazard 
Communication regulations that were not submitted to OSHA for approval 
through its State Plan, even to the extent that California's Hazard 
Communication rule regulated manufacturers and distributers who were 
excluded from coverage under federal OSHA's rule. Indust. Truck Ass'n 
v. Henry, 125 F.3d 1305, 1311-14 (9th Cir. 1997). In the same way, the 
ETS preempts all State and local requirements that bar or limit the 
ability of an employer to require workplace vaccination, testing, and 
face coverings to protected employees against COVID-19 in any respect, 
since OSHA has occupied the entire field of regulation on these issues.
    OSHA's definition of the ``issue'' in this rule should be afforded 
weight, since the OSH Act vests OSHA with standard-setting 
responsibility and, therefore, the authority to determine which 
``issues'' to address with occupational safety and health standards. 
See Indust. Truck, 125 F.3d at 1311 (relying on OSHA's regulation and 
statements in the preamble to identify the relevant ``issue'' for 
preemption purposes in OSHA's Hazard Communication standard).
    Importantly, although OSHA's stated intention is to preempt 
conflicting State and local requirements relating to the issues 
addressed by this standard, OSHA recognizes that the OSH Act does not 
allow, and OSHA does not intend, for the ETS to preempt non-conflicting 
State or local requirements of general applicability. In Gade, the 
Supreme Court qualified its ruling by saving from preemption non-
conflicting State and local ``laws of general applicability (such as 
laws regarding traffic safety or fire safety) that do not conflict with 
OSHA standards and that regulate the conduct of workers and nonworkers 
alike.'' Gade, 505 U.S. at 107. The Majority reasoned that, 
``[a]lthough some laws of general applicability may have a `direct and 
substantial' effect on worker safety, they cannot fairly be 
characterized as `occupational' standards, because they regulate 
workers simply as members of the general public.'' Id.
    During the pandemic, many States and municipal governments have 
adopted requirements intended to protect public health by helping to 
prevent the spread of COVID-19 in public spaces. These have included 
requirements mandating face coverings in indoor public spaces, 
including businesses, government buildings, and schools (see, e.g., 
Baltimore City Health Department, August 10, 2021; Illinois Executive 
Order 2021-20, August 26, 2021; Hawai'i Emergency Proclamation, October 
1, 2021). In addition, in recent months, some States and municipal 
governments have adopted requirements mandating that members of the 
public provide proof of vaccination or recent COVID-19 testing in order 
to enter restaurants, bars, or other businesses or public spaces (see, 
e.g., NYC Emergency Executive Order 225, August 16, 2021 (mandating 
COVID-19 vaccination for most individuals for indoor entertainment, 
recreation, dining and fitness settings)). Requirements such as these 
apply to ``workers and nonworkers alike'' and ``regulate workers simply 
as member of the general public'' and are accordingly not preempted. 
Gade, 505 U.S.at 107.
    Based on OSHA's observations and experience during the past year 
and a half that the pandemic has been ongoing, OSHA is confident that 
protective State and local regulations of general applicability that 
mandate face coverings or vaccination will complement, rather than 
interfere with OSHA's enforcement of the ETS, and also does not intend 
to preempt such requirements. Indeed, OSHA believes that such measures 
have significantly reduced the harmful effects of the pandemic and 
total fatalities. See Steel Institute of NY v. The City of NY, 716 F.3d 
31, 38 (affording some weight to OSHA's view that municipal regulations 
governing construction cranes did not interfere with OSHA's regulatory 
scheme in its crane standards and ultimately adopted OSHA's view in 
finding these municipal regulations were not preempted by OSHA crane 
standards).\83\
---------------------------------------------------------------------------

    \83\ OSHA's Cranes and Derricks in Construction rule directly 
discussed its expectations and intent regarding the preemptive 
effect of the rule, including that it was not intended to preempt 
generally applicable municipal regulations, such as building codes, 
which serve public safety purposes. Cranes and Derricks in 
Construction, 75 FR 47,906, 48,128 (August 9, 2010). This rule also 
includes a provision that requires employers to comply with State 
crane operator licensing requirements that meet the federal floor 
for crane operator certification in the rule. 29 CFR 
1926.1427(c)(1). OSHA has also indicated that its rule would not 
preempt State or local requirements in other rulemakings. See e.g., 
72 FR 7136, 7188 (Feb. 14, 2007) (Preamble to OSHA's most recent 
electrical safety standard) (``State and local fire and building 
codes, which are designed to protect a larger group of persons than 
employees,'' are not preempted); 29 CFR 1910.134(e) (requiring 
compliance with State and local laws by requiring ``a licensed 
health care professional'' to perform a medical evaluation of an 
employee's ability to use a respirator).
---------------------------------------------------------------------------

    In Steel Institute, the Second Circuit held that OSHA's crane 
regulations did not preempt New York City municipal regulations 
governing construction cranes, finding that such regulations were 
requirements of general applicability, notwithstanding their direct 
bearing on worker safety, because their primary purpose and effect was 
to preserve the safety of the general public, and they regulated 
workers and nonworkers alike. Id. The Steel Institute court noted the 
``strong presumption against preemption when states and localities 
``exercise[ ] their police powers to protect the health and safety of 
their citizens.'' Id. at 36, citing Medtronic, Inc. v. Lohr, 518 U.S. 
470, 475 (1996). The Second Circuit was also influenced by the clear 
danger presented to the public by unsafe crane operation. This is 
analogous to the situation here, because exposure to COVID-19 is a 
hazard that directly impacts everyone. Thus, generally applicable State 
and local mandates requiring face coverings or vaccination should not 
be preempted and should


remain in effect, notwithstanding this ETS.\84\
---------------------------------------------------------------------------

    \84\ In addition, some State and local governments have adopted 
vaccination mandates directed at State and/or local government 
employees. The OSH Act and OSHA's standards would not preempt such 
requirements since State or local government employers and employees 
are exempt from OSHA coverage under the OSH Act. 29 U.S.C. 652 (5) 
(defining employer to exclude ``any State or political subdivision 
of a State''). However, many State and local government employers in 
States with OSHA-approved State Plans will be covered by State 
occupational safety and health requirements, and State Plans must 
adopt requirements for State and local government employers, as well 
as covered private sector employers, that are at least as effective 
as federal OSHA's requirements; State Plans may also choose to adopt 
more protective occupational safety and health requirements. 29 
U.S.C. 667(c).
---------------------------------------------------------------------------

    On the other hand, as noted above, this standard will preempt 
requirements that conflict with it, regardless of whether the 
requirements are part of a law of general applicability.\85\
---------------------------------------------------------------------------

    \85\ As previously discussed, bans on mandating vaccinations or 
face coverings have not typically been generally applicable, but 
even the least workplace-specific, most generally applied bans will 
not survive preemption because they directly interfere with the 
ETS's regulatory scheme.
---------------------------------------------------------------------------

    The effect of the ETS on State law requirements in State Plan 
States works somewhat differently. As previously noted, under section 
18 of the OSH Act States that wish to assume responsibility for the 
development and enforcement of ``occupational safety and health 
standards relating to any occupational safety or health issue with 
respect to which a Federal standard has been promulgated'' may submit a 
State Plan to OSHA for approval. Id. section 667(b); see also id. 
section 667(c) (describing requirements for OSHA approval of State 
Plans on issues for which OSHA has adopted standards). There are 22 
States and territories that have OSHA-approved State Plans for private 
employers, and 6 additional States and territories that have OSHA-
approved State Plans for public employers only.
    Under section 18(c)(2) of the OSH Act, State Plans are required to 
adopt and enforce occupational safety and health standards that are at 
least as effective as federal OSHA's requirements. Id. section 
667(c)(2). In addition, the OSH Act requires that State Plans must 
cover State and local government employees (including, e.g., State and 
local school systems within the scope of this rule), even though 
federal OSHA does not have coverage over such employees in States 
without OSHA-approved State Plans.
    Once OSHA promulgates an ETS, OSHA's regulations provide that those 
States have ``30 days after the date of promulgation of the Federal 
standard to adopt a State emergency temporary standard,'' or to 
demonstrate ``that promulgation of an emergency temporary standard is 
not necessary because the State standard is already the same or at 
least as effective as the Federal standard change.'' 29 CFR 
1953.5(b)(1). The new ETS becomes part of the OSHA-approved State Plan 
through the State Plan's submission to OSHA documentation showing it 
adopted an identical ETS or a ``Plan Change Supplement'' showing that 
it has adopted requirements that are ``at least as effective'' as 
federal OSHA's ETS. 29 CFR 1953.5(b)(3); 1953.4.
    Even in States with OSHA-approved State Plans, any State law 
relating to an occupational safety and health issue that OSHA regulates 
is preempted unless it is submitted for OSHA's approval as a supplement 
to the State Plan. Indust. Truck Ass'n, 125 F.3d at 1311 (``If a State 
wishes to regulate an issue of worker safety for which a federal 
standard is in effect, its only option is to obtain the prior approval 
of the Secretary of Labor . . . [and] [i]t would make the state plan 
approval requirement superfluous if a state could pick and choose which 
occupational health and safety regulations to submit to OSHA''). Thus, 
a State or local requirement banning or limiting employer vaccine 
mandates would similarly be preempted because it has not been approved 
by federal OSHA as part of the State Plan. And, indeed, it could not be 
approved by federal OSHA, because such bans or limitations undercut the 
ETS's requirements and are clearly not as effective as the federal ETS. 
See 29 U.S.C. 667(c)(2).\86\
---------------------------------------------------------------------------

    \86\ For example, Arizona has an OSHA-approved State Plan, but 
its vaccination ban, which is not part of its State Plan, is 
preempted by this ETS (see AZ Executive Order 2021-18, Aug. 16, 
2021).
---------------------------------------------------------------------------

    Finally, this provision includes a note that this section 
establishes minimum requirements for employers, that nothing in this 
section prevents employers from agreeing with their employees to 
implement additional measures, and that this section does not supplant 
collective bargaining agreements or other collectively negotiated 
agreements in effect that may have negotiated terms that exceed the 
requirements herein. It also references the National Labor Relations 
Act of 1935, which protects most private-sector employees' right to 
take collective action. The purpose of this note is to remind employers 
and employees that OSHA's ETS establishes a floor for protections, and 
that it does not preclude bargaining for additional protective 
measures. For example, employers might agree to cover the costs of face 
coverings or medical removal, or to a requirement that all employees, 
regardless of vaccination status, wear face coverings while working 
indoors.

B. Scope and Application

    Paragraph (b)(1) of this ETS provides that the ETS applies to all 
employers that have a total of at least 100 employees at any time the 
ETS is in effect. OSHA has determined that the unvaccinated employees 
of these employers face a grave danger of exposure to SARS-CoV-2, 
including the Delta variant, while they are at work (see Grave Danger, 
Section III.A. of this preamble). Because this grave danger finding 
applies to all unvaccinated employees who come into contact with other 
people in indoor work settings as part of their employment, this ETS is 
not limited by industrial sector or NAICS code. Therefore, this 
standard generally covers employers in all workplaces that are under 
OSHA's authority and jurisdiction, including industries as diverse as 
manufacturing, retail, delivery services, warehouses, meatpacking, 
agriculture, construction, logging, maritime, and healthcare.
I. Decision To Limit Coverage of This ETS to Employers With 100 or More 
Employees
    This ETS applies to employers with a total of 100 or more employees 
at any time the standard is in effect. In light of the unique 
occupational safety and health dangers presented by COVID-19, and 
against the backdrop of the uncertain economic environment of a 
pandemic, OSHA established this coverage threshold for four reasons. 
First, OSHA is confident that employers with 100 or more employees will 
be able to meet the standard's requirements promptly, as the emergency 
addressed by the standard necessitates. OSHA is less confident that 
smaller employers can do so without undue disruption. Second, this 
coverage threshold will enable the standard to reach two-thirds of all 
private-sector workers in the nation, providing them with prompt 
protection. Third, the standard will reach the largest facilities, 
where the most deadly outbreaks of COVID-19 can occur. Fourth, the 100-
employee threshold in this standard is comparable with the size 
thresholds established by congressional and agency decisions in 
analogous contexts.
a. Challenges to Feasibility Analysis for Small Businesses
    An OSHA standard, including an ETS, must be both economically and 
technologically feasible. A standard is economically feasible under the 
OSH Act if it neither threatens ``massive dislocation to'' nor upsets 
the ``competitive stability of'' the regulated industries. United 
Steelworkers of Am., AFL-CIO-CLC v. Marshall, 647 F.2d 1189, 1265 (D.C. 
Cir. 1980). Technological feasibility has been interpreted broadly to 
mean ``capable of being done'' Am. Textile Mfrs. Inst. v. Donovan, 452 
U.S. 490, 509-510 (1981).
    As shown in Economic Analysis, Section IV.B. of this preamble, OSHA 
is confident that this standard is feasible for employers with 100 or 
more employees. OSHA is not at this time making any determination about 
whether it would be appropriate to extend the ETS to cover smaller 
employers. Put simply, the agency is requiring that employers it is 
confident can implement the provisions of the standard without delay do 
so. At the same time, the agency is soliciting public comment and 
seeking additional information to assess the ability of smaller 
employers to do so in the rulemaking commenced by this ETS. OSHA will 
determine the issue on the basis of the record, after receiving public 
comment.\87\ The SARS-CoV-2 virus continues to spread rapidly, and each 
day that passes, tens of thousands more people are infected. The 
employees of larger firms should not have to wait for the protections 
of this standard while OSHA takes the additional time necessary to 
assess the feasibility of the standard for smaller employers.
---------------------------------------------------------------------------

    \87\ If OSHA receives information suggesting that a broader 
scope would be appropriate, the agency could expand the scope of the 
ETS quickly through a supplemental action. Fla. Peach Growers Ass'n, 
Inc. v. U. S. Dep't of Labor, 489 F.2d 120, 127 (5th Cir. 1974) 
(``It is inconceivable that Congress, having granted the Secretary 
the authority to react quickly in fast-breaking emergency 
situations, intended to limit his ability to react to developments 
subsequent to his initial response.'')
---------------------------------------------------------------------------

    The pandemic has presented special challenges for small businesses. 
According to a survey conducted during its early stages, 66% of 
businesses with fewer than 100 employees had suffered revenues losses 
exceeding 30%. (SHRM, May 6, 2020a). By contrast, only 27% of larger 
businesses with more than 100 employees had seen revenue drops of more 
than 30% (SHRM, May 6, 2020b). More recently, 61% of the members of the 
National Federation of Independent Businesses, mostly very small 
businesses, responded to a survey reported that they were experiencing 
staff shortages, with half of that group reporting a moderate to 
significant loss of sales because of unfilled positions (NFIB, July 12, 
2021).
    The requirements of the ETS could have a differential impact on 
small businesses compared with larger firms. Many small businesses lack 
separate human resources departments and struggle to carry out HR 
functions. A study found that some 70% of small businesses (with 5 to 
49 employees) handle HR tasks in an ad hoc way. (ADP, December 2016). 
Only 23% of ad hoc managers believed they had the tools and resources 
necessary to perform HR tasks well, and only 19% were fully confident 
in their ability to handle HR tasks without making mistakes (ADP, 
December 2016). Another survey found that HR functions are 
proportionally far more expensive for smaller firms than for larger 
(small firms defined as up to 250 workers) (SHRM, 2015). The ETS 
requires employers to establish new systems to track vaccination status 
among workers, to keep related records, and for firms that allow the 
testing option, to keep records of each test.


These records must be treated as confidential medical records subject 
to detailed regulations, which is not something most smaller employers 
typically need to do or have existing systems in place to address. 29 
CFR 1910.1020. While OSHA has imposed similar requirements on smaller 
employers before, it has typically done so in highly regulated 
industries, such as healthcare, or in industries involving complicated 
industrial processes, which already require a certain degree of 
administrative capacity even when not responding to a grave danger, 
through a rulemaking process that provides additional time for notice 
and implementation, and when there is more time to assess the impact 
that the standard would have on small business. This emergency standard 
by contrast applies across the board to all industries, including less 
regulated retail and service sectors.
    Moreover, OSHA estimates that some 5% of employees may have a 
medical contraindication or request an accommodation from the rule's 
requirements for disability or sincerely held religious belief reasons. 
(Please see Economic Analysis, Section IV.B. of this preamble). 
Assessing these requests may require more resources for smaller firms 
with less experience in this area, particularly if they lack HR staff. 
By the same token, a delay in applying the ETS to businesses with fewer 
than 100 employees would allow those businesses the benefit of learning 
from the models established by larger businesses with respect to 
accommodations. Similarly, implementing the ETS's testing provisions in 
a stepwise fashion will allow OSHA the time necessary to assess any 
impact the new requirements may have on the testing infrastructure and 
related supply chains before considering extending those requirements 
to additional employers.
b. The ETS Provides Prompt Protection for Most of America's Workforce
    The 100 employee threshold means the ETS will reach two-thirds of 
the nation's private sector workforce, providing protection to millions 
of workers while issues regarding smaller firms are reviewed. OSHA 
considered that a 100 employee threshold was superior to a 150 employee 
threshold in this respect, because it would protect more employees: 67% 
rather than 63%, which is a difference of 4.856 million workers. (U.S. 
Census Bureau, May 2021). And while a 50 employee threshold would have 
covered more employees (78%), it would have required additional 
feasibility analysis, while still leaving many employees outside the 
standard. (U.S. Census Bureau, May 2021).
c. The ETS Will Help Prevent Large Outbreaks of COVID-19
    The ETS's focus on employers with more than 100 employees will also 
help prevent large-scale outbreaks. As addressed in more detail in the 
discussion of Grave Danger (Section III.A. of this preamble), all 
unvaccinated employees who work in indoor settings face a grave danger 
from COVID-19, which is why the scope of the ETS is not limited to 
worksites of a specific size. The standard is based on employer size 
primarily because administrative capacity is more closely related to 
employer size. In addition, employer size provides a clear measure that 
is easy for employers (and OSHA) to track, as opposed to an alternative 
such as a workplace-based approach, which could fluctuate from day to 
day and mean more places and information for the employer to track. But 
OSHA also chose the 100 employee size threshold in recognition of the 
fact that larger employers are more likely to have many employees 
gathered in the same location. For employers with 100 or more 
employees, the median number of employees at any one location is 
approximately 50 (the average is also 50). (U.S. Census Bureau, May 
2021). For employers with fewer than 100 employees, the median number 
of any one location is approximately 2 (with an average number of 7) 
(U.S. Census Bureau, May 2021).
    Employees at larger locations are statistically more likely to be 
exposed to someone with COVID-19 during the course of their shifts, and 
thus face a heightened risk of virus transmission. Studies indicate 
that introduction of infection and the risk of infection transmission 
is increased with the size of a gathering (Champredon et al., April, 
2021), and with larger populations (Shacham et al., July 5, 2021). See 
also (Contreras et al., July, 2021) (concluding that outbreaks were 
larger and lasted longer at facilities with more onsite staff). It is 
therefore not surprising that significant COVID-19 outbreaks have 
occurred at large facilities of employers with 100 or more employees 
\88\ (Oregon Health Authority, October 6, 2021; CDPHE, October 6, 
2021). A study of outbreaks in Los Angeles County found that the median 
number of employees in an establishment in which an outbreak occurred 
was 95, well above the 50 employee median for locations of employers 
covered by this rule, indicating that the rule will protect employees 
in the places where outbreaks are most likely to occur. (Contreras et 
al., July, 2021). And those outbreaks occurred even before the 
emergence of the SARS-CoV-2 Delta variant, which the CDC says ``causes 
more infections and spreads faster than early forms of SARS-CoV-2.'' 
(CDC, August 26, 2021) In fact, the studies noted earlier in this 
paragraph were published just as the Delta variant was emerging, 
meaning that the risk of transmission cited in those studies has likely 
increased.
---------------------------------------------------------------------------

    \88\ See, e.g., Oregon Health Authority, October 6, 2021, 
(publishing data on outbreaks in large workplaces including two 
Amazon facilities, several hospitals, and a Walmart distribution 
center); CDPHE, Oct. 6, 2021, (identifying an active Covid outbreak 
in Cargill's Fort Morgan, CO meat processing plant, which employs 
more than 2,000 workers). While some have speculated that clusters 
of infections among employees at the same facility might result 
initially from shared exposures outside of work, the original source 
of the infection would have little bearing on the statistical 
probability of exposure and transmission once the infected people 
are together in the workplace with unvaccinated co-workers. The most 
effective way to prevent further transmission is to protect the 
other workers through vaccination or, when that is not possible, 
identify and remove the infected workers from the workplace as 
quickly as possible.
---------------------------------------------------------------------------

    While virus transmission is certainly not limited to large 
facilities, the potential scope of an outbreak is inherently more 
limited when fewer employees are present. In limiting the scope of the 
ETS to employers with 100 or more employees, OSHA is prioritizing 
coverage of those businesses in which the spread of the virus could 
potentially affect the largest number of employees and for which the 
agency is most confident that it is feasible to apply the standard.
d. Analogous Regulatory Regimes Use Comparable Employee Size Thresholds
    Congress and federal agencies have frequently recognized that an 
employee size threshold may be appropriate in different regulatory 
contexts. They have not settled on any one number as the most 
appropriate, presumably because that depends on balancing different 
considerations that are relevant to the particular context, as OSHA has 
done here. But several analogous regulatory regimes use employee size 
thresholds comparable to the one selected here, in light of similar 
concerns about administrative feasibility.
    For example, the EEOC has issued regulations requiring employers 
with 100 or more employees to submit annual reports related to equal 
employment opportunity in their workforce, in recognition that larger 
employers are better equipped to absorb the types of administrative 
burdens


imposed by surveying, tracking and recordkeeping requirements. See 42 
U.S.C. 2000e-8(c), 29 CFR 1602.7-.14 and 41 CFR 60-1.7(a). In earlier 
measures adopted in response to the COVID-19 pandemic, Congress adopted 
special protections and exemptions based on employee counts. The 
Families First Coronavirus Response Act, Public Law 116-127 (2020), 
sections 7001 and 7003 provided tax credits to businesses with fewer 
than 500 employees to assist compliance with the Act's expansion of 
paid sick and family leave, in recognition of the challenges facing 
smaller employers. Congress again relied on the same 500 employee 
threshold when it later extended tax credits only to employers who 
granted employees paid time off to be vaccinated, implicitly 
acknowledging the financial obstacles that can exist for smaller 
employers for the same activity that this ETS promotes (and without the 
vaccine policy and verification requirement in this ETS). American 
Rescue Plan Act, Public Law 117-2, Sec. 9641 (2021).
    In the Affordable Care Act, Congress set the maximum size of a 
``small employer'' at 100 employees for purposes of allowing greater 
flexibility to these employers. 42 U.S.C.A. 18024(b)(3). Likewise, 
private employers with fewer than 50 employees are exempt from 
complying with the Family and Medical Leave Act, in recognition of 
smaller employers' decreased administrative capacity, as well as their 
inability to easily accommodate employee absences. 29 U.S.C.A. 
2611(2)(b)(2).
e. The 100 Employee Coverage Provision Is a Reasonable Exercise of the 
Secretary's Authority
    OSHA's choice of a 100 employee threshold is based on balancing the 
fundamentally incommensurable considerations described above. Under the 
statute OSHA ``shall'' issue an ETS when employees are exposed to grave 
danger, and is not to follow normal notice and comment procedures to 
build a record. 29 U.S.C. 655(e). But OSHA may not issue an ETS unless 
it shows that the rule is feasible for the employers covered, and it 
has not yet made a feasibility determination for smaller employers. In 
the circumstances of this case, OSHA considered that an ETS was 
urgently needed to protect employees, that a 100 employee threshold 
would protect the great majority of them and prevent the largest 
outbreaks, that it would avoid the delays that would be needed if the 
agency were required to gather information and analyze feasibility for 
smaller employers, and that a comparable size threshold has been found 
appropriate in similar contexts. Where employees are dying every day, 
it is not unreasonable for the agency to prioritize doing what it can 
to address the problem quickly, regardless of whether there are further 
actions it might be able to take later.
    Doing so implements the statutory delegation of authority to the 
agency to establish priorities for issuing standards by giving ``due 
regard to the urgency of the need'' for standards for particular 
workplaces. 29 U.S.C. 655(g). The courts have recognized that this 
provision authorizes the Secretary to make reasonable decisions 
limiting the scope of a standard, particularly where as here the agency 
has said it will address the reserved issue in subsequent rulemaking. 
Forging Indus. Assoc. v. Donovan, 773 F.2d 1436, 1454 (4th Cir. 1985) 
(hearing conservation standard); United Steelworkers of Am. v. 
Marshall, 647 F.2d 1189, 1309-1310 (D.C. Cir. 1980) (lead standard).
    Where competing considerations are in play and there is no clear 
perfect choice, OSHA has a degree of discretion to draw a reasonable 
line. Courts have consistently recognized that agencies have discretion 
to draw reasonable lines. As the D.C. Circuit has explained: An agency 
has ``wide discretion'' in making line-drawing decisions and ``[t]he 
relevant question is whether the agency's numbers are within a zone of 
reasonableness, not whether its numbers are precisely right.'' 
WorldCom, Inc. v. FCC, 238 F.3d 449, 462 (D.C. Cir. 2001) (quotation 
marks omitted). An agency ``is not required to identify the optimal 
threshold with pinpoint precision. It is only required to identify the 
standard and explain its relationship to the underlying regulatory 
concerns.'' Id. at 461-62. Nat'l Shooting Sports Found. v. Jones, 716 
F.3d. 200, 214-215 (D.C. Cir 2013). See also Providence Yakima Med. 
Ctr. v. Sebelius, 611 F.3d 1181, 1190-1191 (9th Cir. 2010).
    For the reasons discussed above, the balance the agency struck here 
falls well within this zone of reasonableness.
II. Explanation of Who Is Included in the 100-Employee Threshold
    The applicability of this ETS is based on the size of an employer, 
in terms of number of employees, rather than on the type or number of 
workplaces. In determining the number of employees, employers must 
include all employees across all of their U.S. locations, regardless of 
employees' vaccination status or where they perform their work. Part-
time employees do count towards the company total, but independent 
contractors do not. As discussed above, OSHA has not found that the 
standard is feasible for firms with fewer than 100 employees, because 
it needs additional time to assess the impact of the standard on these 
employers, particularly as many smaller firms lack separate human 
resources departments and may face additional challenges when carrying 
out human resources functions. In contrast, OSHA has determined that 
the standard is feasible for firms with 100 or more employees, 
regardless of where those employees report to work. These firms 
generally have greater administrative capacities, and including all 
such employers in the scope of this ETS ensures that OSHA can cover 
two-thirds of all workers in the private sector as quickly as possible.
    For a single corporate entity with multiple locations, all 
employees at all locations are counted for purposes of the 100-employee 
threshold for coverage under this ETS. In a traditional franchisor-
franchisee relationship in which each franchise location is 
independently owned and operated, the franchisor and franchisees would 
be separate entities for coverage purposes, such that the franchisor 
would only count ``corporate'' employees, and each franchisee would 
only count employees of that individual franchise. In other situations, 
two or more related entities may be regarded as a single employer for 
OSH Act purposes if they handle safety matters as one company, in which 
case the employees of all entities making up the integrated single 
employer must be counted.
    In scenarios in which employees of a staffing agency are placed at 
a host employer location, only the staffing agency would count these 
jointly employed workers for purposes of the 100-employee threshold for 
coverage under this ETS. Although the staffing agency and the host 
employer would normally share responsibility for these workers under 
the OSH Act, this ETS raises unique concerns in that OSHA has set the 
threshold for coverage based primarily on administrative capacity for 
purposes of protecting workers as quickly as possible, as discussed 
above, and the staffing agency would typically handle administrative 
matters for these workers. Thus, for purposes of the 100-employee 
threshold, only the staffing agency would count the jointly employed 
employees. The host employer, however, would still be covered by this 
ETS if it has 100 or more employees in addition to the employees of the 
staffing agency. For enforcement purposes, traditional joint employer 
principles would apply where both employers are covered by the ETS, as


illustrated further by the examples below. See also https://www.osha.gov/temporaryworkers/.
    On a typical multi-employer worksite such as a construction site, 
each company represented--the host employer, the general contractor, 
and each subcontractor--would only need to count its own employees, and 
the host employer and general contractor would not need to count the 
total number of workers at each site. That said, each employer must 
count the total number of workers it employs regardless of where they 
report for work on a particular day. Thus, for example, if a general 
contractor has more than 100 employees spread out over multiple 
construction sites, that employer is covered under this ETS even if it 
does not have 100 or more employees present at any one worksite. 
Covering the employees of larger employers at multi-employer worksites 
would mitigate the spread of COVID-19 at the workplace even where not 
all employees are covered by this ETS because fully vaccinated 
employees (or unvaccinated employees wearing face coverings and 
submitting to weekly testing) would be less likely to spread the virus 
to unvaccinated workers at the site who are not covered by this ETS.
    The determination as to whether a particular employer is covered by 
the standard should be made separately from whether individual 
employees are covered by the standard's requirements, as described by 
paragraph (b)(3) (e.g., some employers may be covered but have no 
duties with respect to some of their employees under this standard). 
Some additional examples include:
     If an employer has 75 part-time employees and 25 full-time 
employees, the employer would be within the scope of this ETS because 
it has 100 employees.
     If an employer has 150 employees, 100 of whom work from 
their homes full-time and 50 of whom work in the office at least part 
of the time, the employer would be within the scope of this ETS because 
it has more than 100 employees.
     If an employer has 102 employees and only 3 ever report to 
an office location, that employer would be covered.
     If an employer has 150 employees, and 100 of them perform 
maintenance work in customers' homes, primarily working from their 
company vehicles (i.e., mobile workplaces), and rarely or never report 
to the main office, that employer would also fall within the scope.
     If an employer has 200 employees, all of whom are 
vaccinated, that employer would be covered.
     If an employer has 125 employees, and 115 of them work 
exclusively outdoors, that employer would be covered.
     If a single corporation has 50 small locations (e.g., 
kiosks, concession stands) with at least 100 total employees in its 
combined locations, that employer would be covered even if some of the 
locations have no more than one or two employees assigned to work 
there.
     If a host employer has 80 permanent employees and 30 
temporary employees supplied by a staffing agency, the host employer 
would not count the staffing agency employees for coverage purposes and 
therefore would not be covered. (So long as the staffing agency has at 
least 100 employees, however, the staffing agency would be responsible 
for ensuring compliance with the ETS for the jointly employed workers.)
     If a host employer has 110 permanent employees and 10 
temporary employees from a small staffing agency (with fewer than 100 
employees of its own), the host employer is covered under this ETS and 
the staffing agency is not.
     If a host employer has 110 permanent employees and 10 
employees from a large staffing agency (with more than 100 employees of 
its own), both the host employer and the staffing agency are covered 
under this standard, and traditional joint employer principles apply.
     Generally, in a traditional franchisor-franchisee 
relationship, if the franchisor has more than 100 employees but each 
individual franchisee has fewer than 100 employees, the franchisor 
would be covered by this ETS but the individual franchises would not be 
covered.
    As explained earlier, part of OSHA's rationale in adopting the 100-
employee threshold is to focus the ETS on companies that OSHA is 
confident will have sufficient administrative systems in place to 
comply quickly with the ETS. Thus, the ETS applies to all employers who 
have the requisite number of employees at any time this ETS is in 
effect. Along with employers that always have more than 100 employees, 
OSHA intends to cover employers that fluctuate above and below the 100-
employee threshold during the term of the ETS because those employers 
will typically have already developed systems and capabilities for 
compliance; a decrease in the number of employees is therefore unlikely 
to make them less capable of compliance.
    The determination of whether an employer falls within the scope of 
this ETS based on number of employees should initially be made as of 
the effective date of the standard, as set out in paragraph (m)(1). If 
the employer has 100 or more employees on the effective date, this ETS 
applies for the duration of the standard. If the employer has fewer 
than 100 employees on the effective date of the standard, the standard 
would not apply to that employer as of the effective date. However, if 
that same employer subsequently hires more workers and hits the 100-
employee threshold for coverage, the employer would then be expected to 
come into compliance with the standard's requirements. Once an employer 
has come within the scope of the ETS, the standard continues to apply 
for the remainder of the time the standard is in effect, regardless of 
fluctuations in the size of the employer's workforce. For example, an 
employer that has 103 employees on the effective date of the standard, 
but then loses four within the next month, would continue to be covered 
by the ETS. OSHA is confident that employers with 100 or more employees 
at any point while this ETS is in effect have the administrative 
capacity to comply with the ETS, even if the number of employees 
fluctuates somewhat above and below 100.
    Paragraph (b)(2) of this ETS sets forth two exemptions to the 
standard.\89\ Under paragraph (b)(2)(i), this ETS does not apply to 
workplaces covered by the Safer Federal Workforce Task Force COVID-19 
Workplace Safety: Guidance for Federal Contractors and Subcontractors 
(see Safer Federal Workforce Task Force, September 24, 2021). With 
limited exceptions, such as where a medical contraindication, 
disability, or sincerely held religious belief would prevent an 
employee from complying with certain provisions, those guidelines 
require covered


contractors to ensure that all covered contractor employees (1) are 
fully vaccinated by December 8, 2021; (2) follow CDC guidelines for 
masks and physical distancing, including masking and distancing 
requirements based on the employee's vaccination status and the level 
of community transmission of COVID-19 where the workplace is located; 
and (3) designate a person to coordinate COVID-19 workplace safety 
efforts at covered workplaces. Because covered contractor employees are 
already covered by the protections in those guidelines, OSHA has 
determined that complying with this standard in addition to the federal 
contractor guidelines is not necessary to protect covered contractor 
employees from a grave danger posed by COVID-19. Although there may be 
some respects in which the OSHA standard is somewhat more protective, 
such as providing paid leave for vaccination, the federal contractor 
guidelines are somewhat more protective in other respects, such as 
requiring vaccination for everyone who does not have a right to an 
accommodation rather than allowing employees to submit to testing in 
lieu of vaccination. In essence, they are similar but slightly 
different schemes that provide roughly equivalent protection, and OSHA 
has determined that imposing a second set of similar protections on 
covered federal contractors by subjecting them to this ETS in addition 
to the federal contractor guidance is not necessary at this time to 
reduce a grave danger to covered contractor employees from COVID-19.
---------------------------------------------------------------------------

    \89\ Note that, in addition to the scope exceptions contained in 
the ETS itself, which are discussed in this section, there may be 
situations where the ETS does not apply by operation of the OSH Act. 
For example, the OSH Act does not apply to working conditions of 
employees with respect to which other Federal agencies have 
exercised their statutory authority to prescribe or enforce 
standards or regulations affecting occupational safety or health 
(see 29 U.S.C. 653(b)(1)). Moreover, the ETS does not apply where 
states with OSHA-approved occupational safety and health programs 
(``State Plans'') have coverage (see 29 U.S.C. 667). State Plans 
must adopt and enforce COVID-19 requirements that are at least as 
effective as this ETS. Finally, the ETS does not apply to state and 
local government employers in states without State Plans (see 29 
U.S.C. 652(5)).
---------------------------------------------------------------------------

    Under Executive Order 14043, every federal agency must implement a 
program requiring each of its federal employees to be vaccinated 
against COVID-19, except as required by law. 86 FR 50989. OSHA will 
regard a federal agency's compliance with this requirement, and the 
related Safer Federal Workforce Task Force guidance issued under 
section 4(e) of Executive Order 13991 and section 2 of Executive Order 
14043 (including guidance on employer support in the form of paid time 
for vaccination and paid leave for post-vaccination recovery), as 
sufficient to meet its obligation to comply with this ETS under Section 
19 of the OSH Act and Executive Order 12196. In essence, the federal 
government has chosen the mandatory vaccination option of this rule, 
and all federal employees are required to be fully vaccinated by the 
compliance date of this standard, except where entitled to a reasonable 
accommodation. The Safer Federal Workforce Task Force's guidelines for 
vaccination verification are consistent with the ETS's (see Safer 
Federal Workforce Task Force, October 11, 2021). Note, however, that 
under the OSH Act, the U.S. Postal Service is treated as a private 
employer, see 29 U.S.C. 652(5), and it is therefore required to comply 
with this ETS in the same manner as any other employer covered by the 
Act.
    For similar reasons, paragraph (b)(2)(ii) provides that this ETS 
does not apply in settings where any employee provides healthcare 
services or healthcare support services while they are covered by the 
requirements of 29 CFR 1910.502. Section 1910.502 requires a multi-
layered suite of protections for employees covered by its requirements, 
including patient screening and management, facemasks or respirators, 
other personal protective equipment (PPE), limiting exposure to 
aerosol-generating procedures, physical distancing, physical barriers, 
cleaning, disinfection, ventilation, health screening and medical 
management, access to vaccination, and medical removal protection. 
Section 1910.502 was carefully tailored to the healthcare workplaces it 
covers and, given the full suite of protections it requires, including 
(like this ETS) the provision of paid time for vaccination, OSHA has 
determined that it adequately protects the employees covered by its 
requirements from the grave danger posed by COVID-19. Therefore, 
complying with the additional requirements of this ETS is not necessary 
to protect those employees while they are covered by that standard's 
protections.
    OSHA's intent was to leave no coverage gaps between section 
1910.502 and this ETS. In other words, the purpose of paragraph 
(b)(2)(ii) is to ensure that all workers in healthcare and healthcare 
support jobs who are at grave danger from exposure to SARS-CoV-2 are 
protected by either section 1910.502 or this ETS while performing their 
jobs. Therefore, it will be necessary for employers with employees 
covered by section 1910.502 to determine if they also have employees 
covered by this ETS. For example, a healthcare employer with more than 
100 employees that has non-hospital ambulatory care facilities that are 
exempt under section 1910.502(a)(2)(iii) (for non-hospital ambulatory 
care settings where all non-employees are screened prior to entry and 
those with suspected or confirmed COVID-19 are prohibited from entry) 
would be required to protect the employees in those ambulatory care 
facilities under this ETS. Similarly, a retail pharmacy chain that 
operates a series of ambulatory care clinics embedded in its stores, 
where those embedded clinics are the only areas in the store that are 
covered under 1910.502 (see section 1910.502(a)(3)(i)), would have to 
ensure that the remainder of its employees in other parts of its stores 
are protected under this ETS if the company has 100 or more employees 
company-wide, including those covered under 1910.502.
    Paragraph (b)(3) provides that, even where the standard applies to 
a particular employer, its requirements do not apply to employees: (i) 
Who do not report to a workplace where other individuals such as 
coworkers or customers are present; (ii) while working from home; or 
(iii) who work exclusively outdoors. OSHA intends these provisions to 
exempt workplace settings where workers do not interact indoors with 
other individuals, and to exempt work performed in the employee's home 
regardless of whether other individuals may be present in the home.
    OSHA has determined that the provisions of this ETS are not 
necessary to protect employees from COVID-19 when they are working 
alone, or when they are working from home (see Grave Danger, Section 
III.A. of this preamble). These two provisions may overlap in some 
cases, but also can apply to slightly different situations. Paragraph 
(b)(3)(i) would apply to work in a solitary location, such as a 
research station where only one person (the employee) is present at a 
time. In that situation, the employee is not exposed to any potentially 
infectious individuals at work. Paragraph (b)(3)(ii) would apply to 
employees working in their homes, regardless of whether other 
individuals who are not employees of the same employer are present. In 
a home telework environment, many factors--such as the presence of 
family members and other individuals unrelated to the employee's work, 
who may not be fully vaccinated or wearing face coverings--may be 
beyond the employer's control. Employees are typically in the best 
position to manage COVID-19 risks in their homes. Note that the 
exemption in paragraph (b)(3)(ii) only applies to employees while they 
are working from home. An employee who switches back and forth from 
teleworking to working in a setting where other people are present 
(e.g., an office) is covered by this ETS and must be vaccinated if 
required by the employer. If the employer does not require vaccination, 
the teleworking employee must either be vaccinated or complete testing 
and wear a face covering in accordance with their


employer's policy under paragraph (d). How often such an employee must 
be tested for COVID-19 and wear a face covering, however, depends on 
how often they report to the office (see, e.g., paragraph (g)(1)(ii)).
    Paragraph (b)(3)(iii) provides that, even if a particular employer 
is covered by the standard, the requirements of the standard do not 
apply to employees who work exclusively outdoors. OSHA has determined 
that COVID-19 does not pose a grave danger to employees who work 
exclusively outdoors because of the significantly reduced likelihood of 
transmission in outdoor settings. As discussed in more detail in Grave 
Danger (Section III.A. of this preamble), the record contains very 
little evidence of COVID-19 transmission in outdoor settings. And, in 
studies where clusters were identified in worksites characterized as 
being outdoors, the study authors were not able to identify specific 
incidents that led to transmission. In addition, workplaces 
characterized as ``outdoors'' may in fact involve significant time 
spent indoors. For example, on a construction site, workers inside a 
partially complete structure are not truly outdoors, and some 
individuals on a construction site may spend significant amounts of 
time in a construction trailer where other individuals are present. 
Workers at outdoor locations may also routinely share work vehicles. 
These indoor exposures could account for COVID-19 clusters among 
employees at worksites otherwise characterized as being outdoors. And 
employees whose outdoor time is interrupted by the indoor periods will 
still be subject to the requirements in this ETS.
    Studies of athletic teams further indicate that evidence of COVID-
19 clusters among workers characterized as working outdoors could 
actually be caused by indoor exposures. Even where athletes were in 
very close contact during outdoor exposures on the playing field, the 
study authors could not identify a single case of COVID-19 transmission 
between teams that occurred outdoors (see Mack et al., January 29, 
2021; Egger et al., March 18, 2021; Jones et al., February 11, 2021). 
For all of these reasons, and as discussed more fully in Grave Danger 
(Section III.A. of this preamble), OSHA has determined that COVID-19 
does not pose a grave danger to employees who work exclusively 
outdoors.
    As a practical matter, determining the applicability of paragraph 
(b)(3)(iii) depends on the working conditions of individual employees. 
For example, if a landscaping contractor has at least 100 employees and 
is not covered by the exemptions in paragraph (b)(2), the standard 
applies to that employer even if a majority of the company's employees 
work exclusively outdoors. The standard's protections would only apply 
to employees working in indoor settings around other individuals (other 
than telework in their own homes), not to those employees working 
exclusively outdoors. In some cases, it may be true that the standard 
applies to an employer but the employer would not have to implement its 
provisions at all because all of its employees fall within exemptions 
in paragraph (b)(3). Going back to the example of the large landscaping 
contractor, if all indoor workers either work from home or in locations 
where no other individuals are present, and all outdoors workers work 
exclusively outdoors and do not drive to worksites together in a 
company vehicle, the employer would be covered by the ETS but not 
required to comply with its provisions.
    An employee will only be covered by the exemption in paragraph 
(b)(3)(iii) if the employee works exclusively outdoors. Thus, an 
employee who works indoors on some days and outdoors on other days 
would not be exempt from the requirements of this ETS. Likewise, if an 
employee works primarily outdoors but routinely occupies vehicles with 
other employees as part of work duties, that employee is not covered by 
the exemption in paragraph (b)(3)(iii). However, if an employee works 
outdoors for the duration of every workday except for de minimis use of 
indoor spaces where other individuals may be present--such as a multi-
stall bathroom or an administrative office--that employee would be 
considered to work exclusively outdoors and covered by the exemption 
under paragraph (b)(3)(iii) as long as time spent indoors is brief, or 
occurs exclusively in the employee's home (e.g., a lunch break at 
home). Extremely brief periods of indoor work would not normally expose 
employees to a high risk of contracting COVID-19; however, OSHA will 
look at cumulative time spent indoors to determine whether that time is 
de minimis. Thus, if there are several brief periods in a day when an 
employee goes inside, OSHA will total those periods of time when 
determining whether the exception for exclusively outdoors work 
applies.
    Finally, to qualify for this exception, the employee's work must 
truly occur ``outdoors,'' which would not include buildings under 
construction where substantial portions of the structure are in place, 
such as walls and ceiling elements that would impede the natural flow 
of fresh air at the worksite. Workplaces that are truly outdoors 
typically do not include any of the characteristics that normally 
enable transmission of SARS-CoV-2 to occur, such as poor ventilation, 
enclosed spaces, and crowding. As discussed in Bulfone et al. (November 
29, 2020), the lower risk of transmission in outdoor settings (i.e., 
open air or structures with only one wall) is likely due to increased 
ventilation with fresh air and a greater ability to maintain physical 
distancing (see Grave Danger, Section III.A. of this preamble, for more 
information on risk of transmission outdoors).

C. Definitions

    Paragraph (c) of the ETS provides definitions of terms used in the 
section.
    ``Assistant Secretary'' means the Assistant Secretary of Labor for 
Occupational Safety and Health, U.S. Department of Labor, or designee. 
This definition provides clarification about who can request and 
receive records specified in paragraph (l)(3) of this section. A 
designee includes a representative conducting an inspection or an 
investigation.
    ``COVID-19 (Coronavirus Disease 2019)'' means the disease caused by 
SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2). SARS-CoV-
2 is a highly transmissible virus that spreads primarily through the 
respiratory droplets that are produced when an infected person coughs, 
sneezes, sings, talks, or breathes. The nature of the disease, variants 
of SARS-CoV-2, disease transmission, and associated health effects are 
all described in great detail in Grave Danger (Section III.A. of this 
preamble). For clarity and ease of reference, the ETS also uses the 
term ``COVID-19'' when describing exposures or potential exposures to 
SARS-CoV-2. The requirements of the ETS are intended to address the 
grave danger of exposure to COVID-19 in the workplace.
    A ``COVID-19 test'' means a test for SARS-CoV-2 that is: (1) 
Cleared, approved, or authorized, including in an Emergency Use 
Authorization (EUA), by the U.S. Food and Drug Administration (FDA) to 
detect current infection with the SARS-CoV-2 virus (e.g., a viral 
test); (2) administered in accordance with the authorized instructions; 
and (3) not both self-administered and self-read unless observed by the 
employer or an authorized telehealth proctor. Examples of tests that 
satisfy this requirement include tests with specimens that are 
processed by a laboratory (including home or on-site collected 
specimens which are processed either individually or as pooled 
specimens), proctored over-the-counter tests, point of care tests, and 
tests where specimen collection and processing is either done or 
observed by an employer.
    Under paragraph (g), employees who are not fully vaccinated must be 
tested for COVID-19. When an employee must be tested, the test is 
considered acceptable only if the test and the administration of the 
test satisfy the definition of COVID-19 test in this standard.
    COVID-19 tests can broadly be divided into two categories, 
diagnostic tests and antibody tests. Diagnostic tests detect parts of 
the SARS-CoV-2 virus and can be used to diagnose current infection. On 
the other hand, antibody tests look for antibodies in the immune system 
produced in response to SARS-CoV-2, and are not used to diagnose an 
active COVID-19 infection. Antibody tests do not meet the definition of 
COVID-19 test for the purposes of this ETS.
    Diagnostic tests for current infection fall into two categories: 
Nucleic acid amplification tests (NAATs) and antigen tests. NAATs are a 
type of molecular test that detect genetic material (nucleic acids); 
NAATs for COVID-19 identify the ribonucleic acid (RNA) sequences that 
comprise the genetic material of the virus. NAATs can reliably detect 
small amounts of SARS-CoV-2 and are unlikely to return a false-negative 
result. NAATs use many different methods to detect the virus, including 
reverse transcription-polymerase chain reaction (RT-PCR), which is a 
high-sensitivity, high-specificity \90\ test for diagnosing SARS-CoV-2 
infection. Other types of NAATs that use isothermal amplification 
methods include nicking endonuclease amplification reaction (NEAR), 
transcription mediated amplification (TMA), loop-mediated isothermal 
amplification (LAMP), helicase-dependent amplification (HDA), clustered 
regularly interspaced short palindromic repeats (CRISPR), and strand 
displacement amplification (SDA) (CDC, June 14, 2021).
---------------------------------------------------------------------------

    \90\ Test sensitivity indicates the ability of a test to 
correctly identify people who have a disease. Test specificity 
indicates the ability of a test to correctly identify people who do 
not have a disease. A test with high sensitivity and high 
specificity minimizes inaccurate results.
---------------------------------------------------------------------------

    Most NAATs need to be processed in a laboratory with variable time 
to receive results (approximately 1-2 days), but some NAATs are point-
of-care tests with results available in about 15-45 minutes. As of 
October 14, 2021, 264 molecular tests (NAATs) and collection devices 
have EUA from the FDA for COVID-19 (FDA, October 14, 2021b). These 
tests may be acceptable under the ETS.
    Antigen tests may also meet the definition of COVID-19 test under 
this standard. Antigen tests indicate current infection by detecting 
the presence of a specific viral antigen. Most can be processed at the 
point of care with results available in about 1530 minutes. Antigen 
tests generally have similar specificity to, but are less sensitive 
than, NAATs (CDC, October 7, 2021). As of October 14, 2021, thirty-
seven antigen


tests have EUA from the FDA for COVID-19 (FDA, October 14, 2021a). 
These tests may be acceptable under the ETS.
    Most antigen tests and some NAATs are conducted at the point of 
care, which means the test processing and result reading is performed 
at or near the place where a specimen is collected so that results can 
be obtained within minutes rather than hours or days. Rapid point-of-
care tests are administered in various settings operating under a 
Clinical Laboratory Improvement Amendments of 1988 (CLIA) certificate 
of waiver, such as physician offices, urgent care facilities, 
pharmacies, school health clinics, workplace health clinics, long-term 
care facilities and nursing homes, and at temporary locations, such as 
drive-through sites managed by local health organizations (FDA, 
November 16, 2020).
    To be a valid COVID-19 test under this standard, a test may not be 
both self-administered and self-read unless observed by the employer or 
an authorized telehealth proctor. OSHA included the requirement for 
some type of independent confirmation of the test result in order to 
ensure the integrity of the result given the ``many social and 
financial pressures for test-takers to misrepresent their results'' 
(Schulte et al., May 19, 2021). This independent confirmation can be 
accomplished in multiple ways, including through the involvement of a 
licensed healthcare provider or a point-of-care test provider. If an 
over-the-counter (OTC) test is being used, it must be used in 
accordance with the authorized instructions. The employer can validate 
the test through the use of a proctored test that is supervised by an 
authorized telehealth provider. Alternatively, the employer could 
proctor the OTC test itself.
    Employers have the flexibility to select the testing scenario that 
is most appropriate for their workplace. Some employees and employers 
may rely on testing that is conducted by a healthcare provider (e.g., 
doctor or nurse) who arranges for the specimen to be analyzed at a 
laboratory or at a point-of-care testing location (e.g., a pharmacy). 
The involvement of licensed or accredited healthcare providers allows 
employers to have a high degree of confidence in the suitability of the 
test and the test results. Some large employers who set up their own 
on-site testing program may partner with a healthcare organization 
(e.g., a local hospital or clinic) or rely on a licensed healthcare 
provider to help obtain a CLIA certificate of waiver. Other employers 
may simply require that employees perform and read their own OTC test 
while an authorized employee observes the administration and reading of 
the test to ensure that a new test kit was used and that the test was 
administered properly (e.g., nostrils were swabbed), and to witness the 
test result.
    Due to the potential for employee misconduct (e.g., falsified 
results), tests that are both self-administered and self-read are not 
acceptable unless they are observed by the employer or an authorized 
telehealth proctor. Some COVID-19 tests are authorized by the FDA to be 
performed only with the supervision of a telehealth proctor, which is 
someone who is trained to observe sample collection and provide 
instructions and result interpretation assistance to individuals using 
the test. The term ``authorized telehealth proctor'' refers to proctors 
who follow the requirements for proctoring specified by the FDA 
authorization. For a more detailed discussion on COVID-19 testing 
requirements under this ETS, see the Summary and Explanation for 
paragraph (g) (Section VI.G. of this preamble).
    A ``face covering'' means a covering that: (1) Completely covers 
the nose and mouth; (2) is made with two or more layers of a breathable 
fabric that is tightly woven (i.e., fabrics that do not let light pass 
through when held up to a light source); (3) is secured to the head 
with ties, ear loops, or elastic bands that go behind the head. If 
gaiters are worn, they should have two layers of fabric or be folded to 
make two layers; (4) fits snugly over the nose, mouth, and chin with no 
large gaps on the outside of the face; and (5) is a solid piece of 
material without slits, exhalation valves, visible holes, punctures, or 
other openings. This definition includes clear face coverings or cloth 
face coverings with a clear plastic panel that, despite the non-cloth 
material allowing light to pass through, otherwise meet this definition 
and which may be used to facilitate communication with people who are 
deaf or hard-of-hearing or others who need to see a speaker's mouth or 
facial expressions to understand speech or sign language respectively. 
Face coverings can be manufactured or homemade, and they can 
incorporate a variety of designs, structures, and materials. Face 
coverings provide variable levels of protection based on their design 
and construction.
    As explained in paragraph (i), face covering use is required based 
on an employee's vaccination status. The criteria in the definition 
help to ensure that face coverings that are worn by workers who are not 
fully vaccinated will provide effective source control and some degree 
of personal protection. Source control means reducing the spread of 
large respiratory droplets to others by covering a person's mouth and 
nose. The personal protection afforded by face coverings, as well as 
the benefits and necessity, are described in the Summary and 
Explanation for paragraph (i) (Section VI.I. of this preamble).
    Face coverings differ from facemasks and respirators, which are 
also defined in paragraph (c) of this section. Face coverings, unlike 
facemasks and respirators, are not considered to be personal protective 
equipment (PPE) under OSHA's general PPE standard (29 CFR 1910.132), as 
discussed in the Summary and Explanation for paragraph (i) (Section 
VI.I. of this preamble).
    Lastly, face coverings as required by this standard do not have to 
meet a consensus standard, although face coverings that adhere to such 
consensus standards, with design and construction specifications, meet 
the definition and may offer both greater protection and the confidence 
that at least a minimum level of protection has been provided. The 
National Institute for Occupational Safety and Health (NIOSH) 
recommends that employers and workers who want a face covering that 
provides a known level of protection use face coverings that meet a new 
standard, called Workplace Performance and Workplace Performance Plus 
masks, for workplaces. As discussed in the Summary and Explanation for 
paragraph (i) (Section VI.I. of this preamble), the new NIOSH criteria 
and the ASTM Specification for Barrier Face Coverings, F3502-21 (ASTM 
Standard) provide a greater level of source control performance for 
workers when wearing the face covering according to manufacturer's 
instructions. The NIOSH criteria require that face coverings conform to 
the ASTM Standard and meet additional quantitative leakage criteria. 
Although not required by the standard, OSHA notes that face coverings 
that meet ASTM F3502-21 requirements and the new NIOSH criteria may 
offer a higher level of source control and wearer protection than those 
face coverings that do not meet a consensus standard.
    A ``facemask'' means a surgical, medical procedure, dental, or 
isolation mask that is FDA-cleared, authorized by an FDA EUA, or 
offered or distributed as described in an FDA enforcement policy. 
Facemasks may also be referred to as ``medical procedure masks.'' This 
definition provides clarification about the exception to the face 
covering


requirement under paragraph (i)(1)(iii) that permits facemask use in 
lieu of face coverings. OSHA notes that facemasks are not respirators, 
which are also defined in this section.
    Facemasks provide protection against exposure to splashes, sprays, 
and spatter of body fluids. Facemasks offer both source control, as 
defined in this section under face coverings, and protection for the 
wearer. OSHA has previously established that facemasks are essential 
PPE for employees in healthcare, under both the general PPE standard 
(29 CFR part 1910.132) and the Bloodborne Pathogens standard (29 CFR 
part 1910.1030). Although not required, the Summary and Explanation for 
paragraph (i) (Section VI.I. of this preamble) addresses their 
inclusion in this standard. Additional information on such facemasks 
can be found in relevant FDA guidance.
    ``Fully vaccinated'' means (i) a person's status 2 weeks after 
completing primary vaccination with a COVID-19 vaccine with, if 
applicable, at least the minimum recommended interval between doses in 
accordance with the approval, authorization, or listing that is: (A) 
Approved or authorized for emergency use by the FDA; (B) listed for 
emergency use by the World Health Organization (WHO); or (C) 
administered as part of a clinical trial at U.S. site, if the recipient 
is documented to have of primary vaccination with the ``active'' (not 
placebo) COVID-19 vaccine candidate, for which vaccine efficacy has 
been independently confirmed (e.g., by a data and safety monitoring 
board) or if the clinical trial participant from the U.S. sites had 
received a COVID-19 vaccine that is neither approved nor authorized for 
use by the FDA but is listed for emergency use by the WHO. Currently-
authorized FDA vaccines include Janssen (Johnson & Johnson), which is a 
single-dose primary vaccination, and Pfizer-BioNTech and Moderna, which 
have a two-dose primary vaccination series. This definition is 
consistent with the CDC definition of fully vaccinated (CDC, September 
16, 2021).
    The definition of ``fully vaccinated'' also means a person's status 
2 weeks after receiving the second dose of any combination of two doses 
of a COVID-19 vaccine that is approved or authorized by the FDA, or 
listed as a two-dose series by the WHO (i.e., heterologous primary 
series of such vaccines, receiving doses of different COVID-19 vaccines 
as part of one primary series). The second dose of the series must not 
be received earlier than 17 days (21 days with a 4-day grace period) 
after the first dose (CDC, October 15, 2021). OSHA has included this 
because people who have received a heterologous primary vaccination 
series (including mixing of mRNA, adenoviral, and mRNA plus adenoviral 
products) are considered by the CDC to also meet this definition. OSHA 
considers a vaccination series that meets the definition in 
subparagraph (ii) to be a primary vaccination for purposes of the 
requirements to support vaccination in paragraph (f).
    The employer obligations under the ETS differ based on whether each 
employee is fully vaccinated. This definition is relevant to the 
definition of mandatory vaccination policy, in this paragraph (c), as 
well as the provisions under paragraph (d) regarding written 
vaccination policy requirements and relevant procedures for workers who 
are fully vaccinated. Paragraph (e)(2) also addresses fully vaccinated 
employees, including the determination of vaccination status and 
acceptable forms of proof. Lastly, the definition provides clarity with 
regard to the requirements of paragraphs (g) and (i) respectively, 
which contain requirements for regular COVID-19 testing and face 
covering use among employees who are not fully vaccinated.
    Paragraph (e) requires employers to determine each employee's 
vaccination status, including whether they are fully or partially 
vaccinated. By ``partially vaccinated,'' OSHA means someone who has 
started a primary vaccination series but not completed it (e.g., has 
received one dose of a two-dose series) or has completed their primary 
vaccination and two weeks have not elapsed since the last dose of the 
primary vaccination.
    A ``mandatory vaccination policy'' is an employer policy requiring 
each employee to be fully vaccinated. To meet the definition of a 
mandatory vaccination policy, the policy must require: Vaccination of 
all employees, including vaccination of all new employees as soon as 
practicable, other than those employees (1) for whom a vaccine is 
medically contraindicated, (2) for whom medical necessity requires a 
delay in vaccination,\91\ or (3) who are legally entitled to a 
reasonable accommodation under federal civil rights laws because they 
have a disability or sincerely held religious beliefs, practices, or 
observances that conflict with the vaccination requirement. OSHA 
intends that ``employee,'' as used in this definition, includes only 
employees that are covered by this ETS and does not include employees 
who are excluded from coverage under paragraph (b)(3).
---------------------------------------------------------------------------

    \91\ As defined by CDC's informational document, Summary 
Document for Interim Clinical Considerations for Use of COVID-19 
Vaccines Currently Authorized in the United States (CDC, September 
29, 2021).
---------------------------------------------------------------------------

    Paragraph (d)(1) of the standard requires an employer to establish, 
implement, and enforce a written mandatory vaccination policy that 
meets this definition. The benefits of vaccination, including the 
effectiveness of vaccination mandates, are discussed in Grave Danger 
(Section III.A. of this preamble) and Need for the ETS (Section III.B. 
of this preamble).
    OSHA recognizes that vaccination policies may vary, as indicated in 
paragraph (d)(2). Any policy that permits the employee to choose 
between vaccination and COVID-19 testing and face covering use would 
not be considered a mandatory vaccination policy under paragraph 
(d)(1), although such policy is permissible under paragraph (d)(2). In 
some cases, employers may implement vaccination policies that differ by 
location or type of business operation and thus the application of 
paragraph (d)(2) might vary across an employer's workforce. This is 
discussed in greater detail in the Summary and Explanation for 
paragraph (d) (Section VI.D. of this preamble).
    A ``respirator'' is a type of PPE that is certified by NIOSH under 
42 CFR part 84 or is authorized under an EUA by the FDA. These 
specifications are intended to ensure some consistent level of testing, 
approval, and protection and to prevent the use of counterfeit 
respirators that will not offer adequate protection, which is important 
because respirators are intended to protect the wearer when directly 
exposed to hazards. Respirators protect against airborne hazards by 
removing specific air contaminants from the ambient (surrounding) air 
or by supplying breathable air from a safe source. Common types of 
respirators include filtering facepiece respirators (e.g., N95), 
elastomeric respirators, and powered air-purifying respirators (PAPRs). 
Face coverings, facemasks, and face shields are not respirators.
    As stated above, there are various types of respirators that would 
fall within this definition. A filtering facepiece respirator (FFR) is 
a negative-pressure particulate respirator with a non-replaceable 
filter as an integral part of the facepiece or with the entire 
facepiece composed of the non-replaceable filtering medium. N95 FFRs 
are the most common type of FFR and are the type of respirator most 
often used to control exposures to infections transmitted via the 
airborne route. When properly worn, N95 FFRs filter at least 95% of 
airborne particles. An


elastomeric respirator is a tight-fitting respirator with a facepiece 
that is made of synthetic or rubber material that permits it to be 
disinfected, cleaned, and reused according to the manufacturer's 
instructions. Elastomeric respirators are equipped with replaceable 
cartridges, canisters, or filters. Lastly, a powered air-purifying 
respirator (PAPR) is an air-purifying respirator that uses a blower to 
force the ambient air through air-purifying elements to the inlet 
covering.
    This standard does not require the use of respirators. This 
definition is included because it relates to paragraph (i)(1)(iii), 
which exempts employees from wearing face coverings when they are 
wearing respirators or facemasks. In addition, paragraph (i)(4) 
requires employers to permit employees to wear a respirator instead of 
a face covering and permits employers to provide respirators to their 
employees, instead of face coverings. When respirators are used 
pursuant to paragraph (i)(4), the employer must also comply with Sec.  
1910.504, the Mini Respiratory Protection Program.
    NIOSH has developed a set of regulations in 42 CFR part 84 for 
testing and certifying non-powered, air-purifying, particulate-filter 
respirators. To help address concerns about availability during the 
COVID-19 pandemic, the FDA has issued EUAs for certain PPE products, 
including respiratory protective devices such as respirators. For the 
purposes of this standard, respirators certified by NIOSH, under 42 CFR 
part 84 or authorized under an EUA by the FDA meet the definition. 
Additional information on such respirators can be found in relevant FDA 
and NIOSH guidance.
    A ``workplace'' is a physical location (e.g., fixed, mobile) where 
the employer's work or operations are performed. It does not include an 
employee's residence, even if the employee is teleworking from their 
residence. Examples of fixed locations include: Offices, retail 
establishments, co-working facilities, and factories or manufacturing 
facilities. A workplace includes the entire site (including outdoor and 
indoor areas, a structure or a group of structures) or an area within a 
site where work or any work-related activity occurs (e.g., taking 
breaks, going to the restroom, eating, entering or exiting work). The 
workplace includes the entirety of any space associated with the site 
(e.g., workstations, hallways, stairwells, breakrooms, bathrooms, 
elevators) and any other space that an employee might occupy in 
arriving, working, or leaving. Examples of employees who have mobile 
workplaces include maintenance and repair technicians who go to homes 
or businesses to provide repair services, or those who provide delivery 
services.

D. Employer Policy on Vaccination

    Vaccination is a vital tool to reduce the presence and severity of 
COVID-19 cases in the workplace, in communities, and in the nation as a 
whole. Despite the robust protection against COVID-19 that vaccination 
affords, millions of eligible individuals have not yet been vaccinated. 
Current efforts to increase the proportion of the U.S. population that 
is fully vaccinated against COVID-19 are critical to ending the COVID-
19 pandemic (CDC, September 15, 2021). As described more fully in Need 
for the ETS (Section III.B. of this preamble), mandatory vaccination 
policies work. Therefore, OSHA has determined that requiring or 
strongly encouraging vaccination--the most effective and efficient 
control for reducing COVID-19--is key to ensuring the protection of 
workers against the grave danger of exposure to SARS-CoV-2 in the 
workplace (see Grave Danger, Section III.A. of this preamble). 
Therefore, this ETS requires employers to adopt mandatory vaccination 
policies for their workplaces, with an exception for employers that 
instead adopt a policy allowing employees to elect to undergo regular 
COVID-19 testing and wear a face covering at work in lieu of 
vaccination. In Need for the ETS (Section III.B of this preamble), OSHA 
explains its rationale for providing the exception.
    Paragraph (d) of this ETS is a critical element in ensuring 
employees' protection, as it requires covered employers to develop, 
implement, and enforce written policies on COVID-19 vaccination for 
their workforces. Paragraph (d)(1) requires the employer to establish, 
implement, and enforce a written mandatory vaccination policy. As 
defined in paragraph (c), a mandatory vaccination policy is an employer 
policy requiring each employee to be fully vaccinated. Such a policy 
must require vaccination of all employees, other than those employees 
who fall into one of three categories: (1) Those for whom a vaccine is 
medically contraindicated, (2) those for whom medical necessity 
requires a delay in


vaccination, or (3) those who are legally entitled to a reasonable 
accommodation under federal civil rights laws because they have a 
disability or sincerely held religious beliefs, practices, or 
observances that conflict with the vaccination requirement. The policy 
must also require all new employees to be vaccinated as soon as 
practicable.
    Paragraph (d)(2) is a limited exemption from the mandatory 
vaccination policy requirement. As discussed in Need for the ETS 
(Section III.B. of this preamble), vaccination mandates are effective 
at increasing overall vaccination rates and protecting employees and, 
therefore, the agency encourages all employers to implement a mandatory 
vaccination policy. Under paragraph (d)(2), however, employers can 
avoid the mandate in paragraph (d)(1) if the employer establishes, 
implements, and enforces a written policy allowing any employee not 
subject to a mandatory vaccination policy to choose either to: (1) Be 
fully vaccinated against COVID-19 or (2) provide proof of regular 
testing for COVID-19 in accordance with paragraph (g) of this section 
and wear a face covering in accordance with paragraph (i). An employer 
who chooses to operate under paragraph (d)(2), however, must still 
offer the support for vaccination required under paragraph (f) and may 
not prevent employees from getting vaccinated. Adopting a policy under 
paragraph (d)(2) simply means that employees themselves may choose not 
to get vaccinated, in which case they must get tested and wear face 
coverings per the requirements of the standard.
    OSHA recognizes there may be employers who develop and implement 
partial mandatory vaccination policies, i.e., that apply to only a 
portion of their workforce. An example might be a retail corporation 
employer who has a mixture of staff working at the corporate 
headquarters, performing intermittent telework from home, and working 
in stores serving customers. In this type of situation, the employer 
may choose to require vaccination of only some subset of its employees 
(e.g., those working in stores), and to treat vaccination as optional 
for others (e.g., those who work from headquarters or who perform 
intermittent telework). This approach would comply with the standard so 
long as the employer complies in full with paragraph (d)(1) and (d)(2) 
for the respective groups.
    OSHA uses the terms establish, implement, and enforce in paragraph 
(d) to emphasize that it is necessary for an employer to first 
determine its policy and create a written record of that policy. After 
determining the policy, an employer must then ensure that it is 
following the policy, as laid out in its written plan. Finally, 
employers must ensure that they enforce the requirements of their 
policies with respect to their workforce, through training and the use 
of such mechanisms as work rules and the workplace disciplinary system, 
if necessary. These requirements apply to the written policy required 
under paragraph (d), whether employers choose to implement the 
mandatory vaccination policy under paragraph (d)(1) or utilize the 
exemption under paragraph (d)(2) for all or a portion of their 
workforce.
    To ensure that employers' vaccination policies under paragraph (d) 
are comprehensive and effective, the policies should address all of the 
applicable requirements in paragraphs (e)-(j) of this standard, 
including: Requirements for COVID-19 vaccination; applicable exclusions 
from the written policy (e.g., medical contraindications, medical 
necessity requiring delay in vaccination, or reasonable accommodations 
for workers with disabilities or sincerely held religious beliefs); 
information on determining an employee's vaccination status and how 
this information will be collected (as described in paragraph (e)); 
paid time and sick leave for vaccination purposes (as described in 
paragraph (f)); notification of positive COVID-19 tests and removal of 
COVID-19 positive employees from the workplace (as described in 
paragraph (h)); information to be provided to employees (pursuant to 
paragraph (j)--e.g., how the employer is making that information 
available to employees); and disciplinary action for employees who do 
not abide by the policy. In addition to addressing the requirements of 
paragraphs (e)-(j) of this standard, the employer should include all 
relevant information regarding the policy's effective date, who the 
policy applies to, deadlines (e.g., for submitting vaccination 
information, for getting vaccinated), and procedures for compliance and 
enforcement, all of which are necessary components of an effective 
plan. Having a comprehensive written policy will provide a solid 
foundation for an effective COVID-19 vaccination program, while making 
it easier for employers to inform employees about the program-related 
policies and procedures, as required under paragraph (j)(1).
    If an employer utilizes the exemption under paragraph (d)(2), its 
workplace may contain employees who are vaccinated and unvaccinated. 
This might be the case even for employers who establish a mandatory 
vaccination policy under paragraph (d)(1); for example, an employer 
with a mandatory vaccination policy might have employees who cannot be 
vaccinated for medical reasons. Given the additional safety protocols 
under this standard for individuals who are not fully vaccinated (see 
paragraphs (g) and (i)), an employer who has both vaccinated and 
unvaccinated employees will have to develop and include the relevant 
procedures for two sets of employees in the written policy. The 
procedures for those who are fully vaccinated should contain all the 
information previously discussed relevant to establishing, 
implementing, and enforcing a comprehensive written policy. However, 
the procedures applicable to employees who are not fully vaccinated 
(i.e., those who decline vaccination, those who are unable to receive 
vaccination and are, absent undue hardship to their employers, entitled 
to reasonable accommodation) and those who are unable to provide proof 
of vaccination as required by paragraph (e) (who must be treated as not 
fully vaccinated), must include COVID-19 testing and face covering use 
as required by paragraphs (g) and (i), respectively, unless the 
reasonable accommodation from vaccination removes the employee from the 
scope of Sec.  1910.501 (e.g., full time telework consistent with one 
of the exceptions in Sec.  1910.501(b)(3)). OSHA intends that such an 
employer will develop one written plan that includes different policies 
and procedures for vaccinated and unvaccinated employees. The 
requirements of paragraphs (e), (f), (h), and (j) should be addressed 
in the policy regardless of the vaccination requirements adopted by the 
employer.
    As with all elements of the written plan, an effective written plan 
will explain the testing requirements contained in paragraph (g) for 
unvaccinated employees, and how the employer will implement and enforce 
those policies. As described in paragraph (g)(1), the testing 
requirements differ for employees who report at least once every 7 days 
to a workplace compared to those who do not. Thus, the policy may 
describe different testing procedures for those different groups of 
employees, depending on how often they physically report to a workplace 
where other individuals are present. As described in paragraph (g)(3), 
the testing requirements are temporarily suspended for 90 days 
following a positive COVID-19 test or diagnosis. Thus, the employer's 
policy and procedures to implement this temporary suspension of

testing should be included in their written workplace policy. In 
addition to the testing requirements in paragraph (g), an effective 
policy must address mandatory face covering use as described in 
paragraph (i), including procedures for employee compliance. Employers 
can get more information on the requirements for paragraphs (e) through 
(j), and what they must do to comply with those provisions of the 
standard, in the relevant Summary and Explanation sections (see Section 
VI. of this preamble).
    As an employer develops their written policy, they must address how 
the policy will apply to new employees. Although many new hires will be 
fully vaccinated, there should be procedures within the plan to collect 
information about the new employee's vaccination status, and determine 
when an unvaccinated new hire must be vaccinated and, for employers 
using a plan under paragraph (d)(2), when COVID-19 testing and face 
covering use will commence if an employee remains unvaccinated. All new 
hires should be treated similarly to any employee who has not entered 
the workplace in the last seven days and will need to be fully 
vaccinated or provide proof of a negative COVID-19 test within the last 
seven days prior to entering the workplace for the first time. It is 
not OSHA's intention to discourage employers from hiring new employees, 
but rather to ensure that new employees are as well-protected from 
COVID-19 hazards in the workplace as current employees and are less 
likely to spread the virus to other employees.
    An employer may have already developed and implemented a written 
policy on vaccination, testing, and/or face covering use to protect 
employees from COVID-19. It is not OSHA's intent for employers to 
duplicate current effective policies covering the requirements of this 
ETS; however, each employer with a current policy must evaluate that 
policy to ensure it satisfies all of the requirements of this rule. 
Employers with existing policies must modify and/or update their 
current policies to incorporate any missing required elements, and must 
provide information on these new updates or modifications to all 
employees in accordance with paragraph (j)(1). Once the employer has 
developed its policy pursuant to paragraph (d), the policy must be 
reduced to writing in order to be compliant with paragraph (d).
    The note to paragraph (d) was included in recognition that, under 
federal law, some employees may be entitled to a reasonable 
accommodation from their employer, absent undue hardship. If the worker 
requesting a reasonable accommodation cannot be vaccinated and/or wear 
a face covering because of a disability, as defined by the Americans 
with Disabilities Act (ADA), that worker may be entitled to a 
reasonable accommodation. In addition, if the vaccination, and/or 
testing for COVID-19, and/or wearing a face covering conflicts with a 
sincerely held religious belief, practice or observance, a worker may 
be entitled to a reasonable accommodation. Such accommodations exist 
independently of the Occupational Safety and Health Act and, therefore, 
OSHA does not administer or enforce these laws. Examples of relevant 
federal laws under which an accommodation can be requested include the 
Americans with Disabilities Act (ADA) and Title VII of the Civil Rights 
Act of 1964.

employers in navigating employees' requests for accommodations, 
including the process for determining a reasonable accommodation and 
information on undue hardship (EEOC, October 25, 2021). An additional

19 Vaccines Currently Authorized in the United States (CDC, September

receiving a COVID-19 vaccine.

E. Determination of Employee Vaccination Status

    To comply with the requirements of the standard, it is essential 
that employers are aware of each employee's vaccination status. As 
discussed in the Summary and Explanation for paragraph (d) (Section 
VI.D. of this preamble), effective implementation and enforcement of a 
written vaccination policy requires the employer to know the 
vaccination status of all employees. Furthermore, the employer must 
know each employee's vaccination status in order to ensure that the 
vaccination, testing, and face covering requirements of the standard 
are met. As such, paragraph (e) includes provisions for determining 
each employee's vaccination status. The standard requires employers to 
determine the vaccination status of each employee (paragraph (e)(1)), 
and also to maintain records of each employee's vaccination status, 
preserve acceptable proof of vaccination for each employee who is fully 
or partially vaccinated, and maintain a roster of each employee's 
vaccination status (paragraph (e)(4)). As discussed more fully below, 
maintenance of records in accordance with this paragraph is subject to 
applicable legal requirements for confidentiality of medical 
information. Additional provisions in paragraph (e) define acceptable 
proof of vaccination status for vaccinated employees (paragraph (e)(2)) 
and provide that any employee who does not submit an acceptable form of 
proof of vaccination status must be treated as not fully vaccinated 
(paragraph (e)(3)).
    Paragraph (e)(1) requires the employer to determine the vaccination 
status of each employee, including whether the employee is fully 
vaccinated. Under paragraph (e)(2), the employer must require each 
vaccinated employee to provide acceptable proof of vaccination status, 
including whether they are fully or partially vaccinated. This is an 
ongoing requirement for the employer (i.e., the employer needs to 
update this information as employees proceed through the vaccination 
process).
    Paragraph (e)(2) defines what ``acceptable proof of vaccination 
status'' means for purposes of the ETS, and


employers must accept any of the proofs listed in accordance with the 
terms of the standard and as explained more fully below. Under 
paragraph (e)(2), the following are acceptable for proof of 
vaccination: (i) The record of immunization from a health care provider 
or pharmacy; (ii) a copy of the U.S. CDC COVID-19 Vaccination Record 
Card (CDC Form MLS-319813_r, published on September 3, 2020) (CDC, 
October 5, 2021); (iii) a copy of medical records documenting the 
vaccination; (iv) a copy of immunization records from a public health, 
state, or tribal immunization information system; or (v) a copy of any 
other official documentation that contains the type of vaccine 
administered, date(s) of administration, and the name of the health 
care professional(s) or clinic site(s) administering the vaccine(s).
    To be acceptable as proof of vaccination, any documentation should 
generally include the employee's name, type of vaccine administered, 
date(s) of administration, and the name of the health care 
professional(s) or clinic site(s) administering the vaccine(s). In some 
cases, state immunization records may not include one or more of these 
data fields, such as clinic site; in those circumstances, an employer 
can still rely upon the State immunization record as acceptable proof 
of vaccination. OSHA notes that clinic sites can include temporary 
vaccination facilities used during large vaccine distribution 
campaigns, such as schools, churches, or sports stadiums. Copies, 
including digital copies, of the listed forms of proof are acceptable 
means of documentation so long as they clearly and legibly display the 
necessary information. Digital copies can include, for example, a 
digital photograph, scanned image, or PDF of an acceptable form of 
proof. Some state governments are utilizing digital COVID-19 vaccine 
records showing the same information as the U.S. CDC COVID-19 
Vaccination Record Card (CDC Form MLS-319813_r, published on September 
3, 2020) and providing quick response (QR) codes that when scanned will 
provide the same information (see, e.g., New York State Government, 
n.d., Retrieved October 4, 2021). In certain states, the QR code 
confirms the vaccine record as an official record of the state (see, 
e.g., State of California, n.d., Retrieved October 7, 2021) and 
therefore would provide acceptable proof of vaccination under the ETS 
(see paragraph (e)(2)(iv)). However, as discussed later, the employer 
must retain a copy of the vaccination information retrieved when the QR 
code is scanned, not just the QR code itself, to comply with paragraph 
(e)(4). In requesting proof of vaccination, the employer must take care 
to comply with any applicable Federal laws, including requirements 
under the Privacy Act, 5 U.S.C. 552a, and the Americans with 
Disabilities Act (ADA), 42 U.S.C. 12101 et seq.
    Each employee who has been partially or fully vaccinated should be 
able to provide one of the forms of acceptable proof listed above 
(paragraphs (e)(2)(i)-(e)(2)(v)). An employee who does not possess 
their COVID-19 vaccination record (e.g., because it was lost or stolen) 
should contact their vaccination provider (e.g., local pharmacy, 
physician's office) to obtain a new copy or utilize their state health 
department's immunization information system. In instances where an 
employee is unable to produce acceptable proof of vaccination under 
paragraphs (e)(2)(i)-(e)(2)(v), paragraph (e)(2)(vi) provides that a 
signed and dated statement by the employee will be acceptable. The 
employee's statement must: (A) Attest to their vaccination status 
(fully vaccinated or partially vaccinated); (B) attest that they have 
lost or are otherwise unable to produce proof required by the standard; 
and (C) include the following language: ``I declare (or certify, 
verify, or state) that this statement about my vaccination status is 
true and accurate. I understand that knowingly providing false 
information regarding my vaccination status on this form may subject me 
to criminal penalties.'' The note to paragraph (e)(2)(vi) explains that 
an employee who attests to their vaccination status should, to the best 
of their recollection, include the following information in their 
attestation: The type of vaccine administered; date(s) of 
administration; and the name of the health care professional(s) or 
clinic site(s) administering the vaccine(s). For example, some of the 
information may be easier to recall, such as receiving a vaccine at a 
mass vaccination site or local pharmacy, while the dates of 
administration might only be remembered as falling within a particular 
month or months. OSHA understands that employees may not be able to 
recall certain information, such as the type of vaccine received. 
Employees providing attestations should include as much of this 
information as they can remember to the best of their ability.
    Any statement provided under paragraph (e)(2)(vi) must include an 
attestation that the employee is unable to produce another type of 
proof of vaccination (paragraph (e)(2)(vi)(B)). Thus, before an 
employee statement will be acceptable for proof of vaccination under 
paragraph (e)(2)(vi), the employee must have attempted to secure 
alternate forms of documentation via other means (e.g., from the 
vaccine administrator or their state health department) and been 
unsuccessful in doing so. The agency recognizes that securing 
vaccination documentation may be challenging for some members of the 
workforce, such as migrant workers, employees who do not have access to 
a computer, or employees who may not recall who administered their 
vaccines (e.g., if the vaccination was provided at a temporary 
location, such as a church, or during a state or local mass vaccination 
campaign). Thus, for employees who have no other means of obtaining 
proof of vaccination, the standard permits employers to accept 
attestations meeting the requirements in paragraph (e)(2)(vi) as proof 
of vaccination. However, employers should explain to their employees 
that they need to produce vaccination proof through the other means 
listed in paragraph (e)(2), such as by contacting the vaccination 
administrator, if they are able to do so. Once the employee has 
provided a signed and dated attestation that meets the requirements of 
paragraph (e)(2)(vi), the employer no longer needs to seek out one of 
the other forms of vaccination proof for that employee and, depending 
on the content of the attestation, the employer may consider that 
employee either fully or partially vaccinated for purposes of the ETS.
    Recently, there has been evidence of fraud associated with people 
attesting to their vaccination status (Bergal, September 16, 2021). 
While employers may not invite or facilitate fraud, the ETS does not 
require employers to monitor for or detect fraud. By defining what 
constitutes acceptable proof of vaccination under the ETS, OSHA is 
ensuring that employers can accept proof meeting the requirements of 
paragraph (e) for purposes of compliance with the standard. However, 
the standard's requirements for proof of vaccination are integral to 
ensuring that employees are protected appropriately, either through 
vaccination (the preferred and most effective workplace control in this 
ETS), or through regular testing and use of face coverings. Thus, it is 
paramount that employees provide truthful information regarding their 
vaccination status.
    As discussed in more detail in the Summary and Explanation for 
paragraph (j) (Section VI.J. of this section), 18 U.S.C. 1001(a), which 
provides for fines or imprisonment of generally up to 5 years for any 
person who ``in any matter within the


jurisdiction'' of the executive branch U.S. Government ``knowingly and 
willfully'' engages in any of the following:
    (1) Falsifies, conceals, or covers up by any trick, scheme, or 
device a material fact;
    (2) makes any materially false, fictitious, or fraudulent statement 
or representation; or
    (3) makes or uses any false writing or document knowing the same to 
contain any materially false, fictitious, or fraudulent statement or 
entry.
    Similarly, the OSH Act recognizes that OSHA's ability to protect 
workers' safety and health hinges on truthful reporting. For that 
reason section 17(g) of the OSH Act subjects anyone who ``knowingly 
makes any false statement, representation, or certification in any 
application, record, report, plan, or other document filed or required 
to be maintained pursuant to this chapter'' to criminal penalties. 29 
U.S.C. 666(g). False statements made in any proof submitted under 
paragraph (e)(2) of the standard could fall under either or both of 18 
U.S.C. 1001 or section 17(g) of the OSH Act. And by requiring a 
specific declaration about the truth and accuracy of employee 
statements provided under paragraph (e)(2)(vi), employees who are 
unable to provide any means of proof other than their own attestation 
are being made aware that their words are being held to the same 
standard of truthfulness as any other record presented for proof of 
vaccination.
    OSHA notes that these same prohibitions on false statements and 
documentation can apply to employers. If an employer knows that proof 
submitted by an employee is fraudulent, and even with this knowledge, 
accepts and maintains the fraudulent proof as a record of compliance 
with this ETS, it may be subject to the penalties in 18 U.S.C. 1001 and 
17(g) of the OSH Act.
    Paragraph (e)(3) provides the mechanism for employers to determine 
vaccination status for employees who do not submit any of the 
acceptable forms of proof of vaccination status. Under paragraph 
(e)(3), any employee who does not provide their employer with one of 
the acceptable forms of proof of vaccination status in paragraph (e)(2) 
must be treated as not fully vaccinated for the purpose of the 
standard. An unvaccinated employee does not need to provide any 
documentation regarding vaccination status under this ETS; however, 
failing to provide acceptable proof of vaccination status will signal 
the employer to consider the employee as not fully vaccinated and to 
note that as their status in the roster. For employers that include 
COVID-19 testing in their written policies under paragraph (d), 
employees without acceptable proof of vaccination status must submit to 
weekly tests (as required by paragraph (g)) and wear a face covering 
(as required by paragraph (i)).
    Paragraph (e)(4) requires the employer to maintain a record of each 
employee's vaccination status and preserve acceptable proof of 
vaccination for each employee who is fully or partially vaccinated. As 
discussed previously, the employer has various options for acquiring 
proof of vaccination from each employee. An employer may allow 
employees to provide a digital copy of acceptable records, including, 
for example, a digital photograph, scanned image, or PDF of such a 
record that clearly and legibly displays the necessary vaccination 
information. However, to be in compliance with paragraph (e)(4), the 
employer must ensure they are able to maintain a record of each 
employee's vaccination status. Therefore, obtaining an employee's 
vaccination information verbally would not comply with paragraph (e)(2) 
or satisfy the record maintenance requirements of the standard. 
Similarly, the record maintenance requirements of paragraph (e)(4) 
cannot be fulfilled by an employee merely showing the employer their 
vaccination status (e.g., by bringing the CDC COVID-19 vaccination card 
to the workplace and showing it to an employer representative or 
showing an employer representative a picture of the immunization 
records on a personal cellphone). To satisfy paragraph (e)(4), the 
employer must retain a copy of the documentation. As mentioned above, 
some states and local governments utilize QR codes to facilitate proof 
of vaccination. This can be an acceptable form of proof for compliance 
with the standard so long as the employer retains a copy of the 
information retrieved by scanning the QR code and maintains that 
record. Required records of vaccination status can be maintained 
physically or electronically, but the employer must ensure they have 
access to the records at all times.
    In addition to obtaining and maintaining individual records of each 
employee's vaccination status and preserving acceptable proof of 
vaccination for each employee who is partially or fully vaccinated, 
under paragraph (e)(4) the employer must maintain a roster of each 
employee's vaccination status, subject to applicable confidentiality 
requirements. The roster must list all employees and clearly indicate 
for each one whether they are fully vaccinated, partially (not fully) 
vaccinated, not fully vaccinated because of a medical or religious 
accommodation (see Note to paragraph (d)), or not fully vaccinated 
because they have not provided acceptable proof of their vaccination 
status. As noted previously, any employee that has not provided 
acceptable proof of their vaccination status must be treated as not 
fully vaccinated. Although unvaccinated employees will not have proof 
of vaccination status, the standard requires the employer to include 
all employees, regardless of vaccination status, on the roster.
    The roster allows the employer to easily access the vaccination 
status for any employee quickly and easily. This will be useful should 
the employer need to respond to a request from an employee or employee 
representative for the aggregate number of fully vaccinated employees 
at a workplace (along with the total number of employees at that 
workplace), as required under paragraph (l)(2). Additionally, the 
roster will help the employer implement the written policy developed in 
accordance with paragraph (d) and comply with other requirements of the 
ETS. And finally, the roster, which must be provided to OSHA on request 
(paragraph (l)(3)), will aid OSHA's ability to effectively and 
efficiently enforce this ETS.
    The records and roster required by paragraph (e)(4) are considered 
to be employee medical records and must be maintained as such records 
in accordance with 29 CFR 1910.1020 and must not be disclosed except as 
required or authorized by this ETS or other federal law, including the 
Americans with Disabilities Act (ADA), 42 U.S.C. 12101 et seq. These 
records and roster are not subject to the retention requirements of 29 
CFR 1910.1020(d)(1)(i) but must be maintained and preserved while this 
ETS remains in effect. OSHA considers vaccination records required by 
paragraphs (e)(2) and (e)(4) of the ETS to be employee medical records 
concerning the health status of an employee and is requiring this 
personally identifiable medical information to be maintained in a 
confidential manner. OSHA notes that under paragraph (e)(4), 
vaccination records and rosters are employee medical records, and must 
be treated as employee medical records under 29 CFR 1910.1020, without 
regard to whether the records satisfy the definition of employee 
medical record at 29 CFR 1910.1020(c)(6)(i).
    Paragraph (e) in 29 CFR 1910.1020 includes requirements for access 
to employee medical records by


employees, their designated representatives, and OSHA. However, as 
discussed in more detail below, paragraph (l) of the ETS includes 
specific timeframes within which employers must make vaccine records 
available to employees, OSHA, and other specified individuals. 
Accordingly, the timeframes for providing access to employee medical 
records in 29 CFR 1910.1020(e) do not apply, and employers must follow 
the specific timeframes set forth in paragraph (l) of the ETS for 
providing access to vaccination records.
    Additionally, 29 CFR 1910.1020(d) addresses the preservation of 
employee exposure and medical records. Paragraph (d)(1)(i) in section 
1910.1020 generally provides that unless a specific occupational safety 
and health standard provides a different period of time, each employer 
must preserve and maintain employee medical records for at least the 
duration of employment plus thirty (30) years. Paragraph (e)(4) of the 
ETS specifically provides that the vaccination records required by the 
ETS are not subject to the retention requirements of 29 CFR 
1910.1020(d)(1)(i). Instead, paragraph (e)(4) states that vaccination 
records must be maintained and preserved only so long as the ETS 
remains in effect.
    Finally, while the provisions on timeframes for access to records 
and the retention provisions of 29 CFR 1910.1020 do not apply to 
vaccine records required by the ETS, other provisions in that 
regulation can still apply. For example, 29 CFR 1910.1020(h) includes 
requirements for the transfer of employee medical records when an 
employer ceases to do business.
    OSHA recognizes the possibility that an employer may have already 
collected information about the vaccination status of employees, 
including proof of vaccination, prior to the effective date of this 
ETS. Under paragraph (e)(5), when an employer has ascertained employee 
vaccination status prior to the effective date of the ETS through 
another form of attestation or proof, and retained records of that 
ascertainment, the employer is exempt from the requirements in 
paragraphs (e)(1)-(e)(3). The exemption applies only for each employee 
whose fully vaccinated status has been documented prior to the 
effective date of the standard. For example, an employer may have asked 
each employee to self-report their vaccination status without requiring 
the employee to provide any form of proof. If that self-reporting was 
through oral conversation only, and not documented in some way, the 
employer is not considered to have retained records of that 
ascertainment for the purposes of this ETS. However, if, for example, 
the employer had the employees provide their vaccine information on a 
dated form, or through individual emails retained by the employer, or 
on an employer portal specifically created for employees to provide 
documentation status, or the employer created and retained some other 
means of documentation, the employer is considered to have retained 
records of ascertainment for the purposes of this ETS. Even if the 
record does not have all of the elements of the acceptable forms of 
proof listed in paragraph (e)(2), so long as the employer has 
ascertained employee vaccination status prior to the effective date of 
the ETS through another form of attestation or proof, and retained 
records of that ascertainment, the employer does not need to re-
determine vaccination status (paragraph (e)(1)) or obtain proof of 
vaccination status (paragraph (e)(2)) for fully vaccinated employees. 
For purposes of paragraph (e)(4), the employer's records of vaccination 
status for each employee whose fully vaccinated status was previously 
documented constitute acceptable proof of vaccination. However, the 
employer must still develop a roster of each employee's vaccination 
status and include on that roster the employees for whom it had 
previously determined and retained records of vaccination status. OSHA 
notes that if the employer has not ascertained employee vaccination 
status for employees prior to the effective date of the ETS, then all 
requirements of paragraph (e) would apply. And all requirements of 
paragraph (e) also apply with respect to employees for whom the 
employer ascertained only partial vaccination status prior to the 
effective date of the ETS.

F. Employer Support for Employee Vaccination

    As discussed in the Summary and Explanation for paragraph (d) 
(Section VI.D. of this preamble), as well as in Grave Danger and Need 
for the ETS (Sections III.A. and III.B. of this preamble), vaccination 
is the single most efficient and effective method for protecting 
unvaccinated workers from the grave danger posed by COVID-19. This 
emergency temporary standard is therefore designed to strongly 
encourage vaccination. As discussed in detail below, paragraph (f) 
requires employers to support vaccination by providing employees 
reasonable time, including up to four hours of paid time, to receive 
each primary vaccination dose, and reasonable time and paid sick leave 
to recover from side effects experienced following each primary 
vaccination dose. For purposes of the requirements to support 
vaccination in paragraph (f), OSHA considers a vaccination series that 
meets the criteria in subparagraph (ii) of the definition of ``fully-
vaccinated'' (i.e., a heterologous primary series of such vaccines, 
receiving doses of different COVID-19 vaccines as part of one primary 
series) to be a primary vaccination series, along with the primary 
vaccination described in subparagraph (i) of that definition (see the 
Summary and Explanation for paragraph (c), Section VI.C. of this 
preamble, for more information on the definition of fully vaccinated).
    Removing logistical barriers to obtaining vaccination is essential 
to increasing workforce vaccination rates, and one such barrier for 
many employees is their lack of time off of work to receive the vaccine 
and recover from any potential side effects (SEIU Healthcare, February 
8, 2021). Employees' concerns about missing work to obtain and recover 
from a COVID-19 vaccination dose are well documented. In a McKinsey 
survey, 12% of respondents stated that the time spent away from work to 
get vaccinated or due to vaccine side effects was a barrier to 
vaccination (Azimi et al., April 9, 2021). In a survey conducted of 
unvaccinated adults in April 2021, a fifth of respondents said they 
were very or somewhat concerned that they may need to take time off to 
go and get the vaccine, and 48% of respondents said that they were very 
or somewhat concerned that they might miss work if


the vaccine side effects make them feel sick (KFF, May 6, 2021). Black 
and Hispanic adults were particularly worried about the potential time 
necessary to receive the vaccine and to recover from vaccine side 
effects; 64% of unvaccinated Hispanic adults and 55% of unvaccinated 
Black adults expressed concern that they might have to miss work due to 
the side effects of a COVID-19 vaccine, and 30% of Hispanic adults and 
23% of Black adults were concerned that they might need to take time 
off work to get a COVID-19 vaccine (KFF, May 6, 2021; KFF, May 17, 
2021). News and journal articles further evince this concern (Roy et 
al., December 29, 2020; Cleveland Documenters, 2021; Rosenberg and 
Stein, August 18, 2021).
    This concern reflects the fact that many workers do not have access 
to paid time off to receive vaccination or to recover from side 
effects. A KFF survey found that only half of all workers reported that 
their employer provided them with paid time off either to get a COVID-
19 vaccine or to recover from any side effects (KFF, June 30, 2021). A 
subsequent KFF survey found that only about one-third of workers were 
sure that their employer offered them paid time off to get a COVID-19 
vaccine and recover from side effects (KFF, September 28, 2021). 
Although employee access to paid sick leave is less of a concern for 
employers with 100 or more employees, approximately 12% of employees in 
these situations do not have paid sick leave (BLS, September 2021) and 
in some cases, employees may have already exhausted paid sick leave 
they have received and would need additional time from their employers 
to recover from vaccine side effects.
    The scarcity of paid time off for vaccination and side effect 
recovery is particularly acute for certain demographic groups. The June 
2021 KFF survey found that only 38% of Black workers reported getting 
either paid time off to get a COVID-19 vaccine or to recover from side 
effects, and that only 41% of workers with household incomes less than 
$40,000 annually had access to such paid time off (KFF, June 30, 2021). 
Similarly, the September 2021 KFF survey found that lower-wage workers 
were particularly unlikely to report access to paid time off for 
vaccination or recovery, with only 23% of workers whose household 
incomes was less than $40,000 reporting that they could take paid time 
off to get vaccinated, and only 28% of that group reporting that they 
could take paid time off to recover from side effects (KFF, September 
28, 2021). Lower-wage workers' lack of access to paid time off for 
vaccination comports with a different report indicating that, before 
the pandemic, about 65% of the lowest-wage workers had no access to 
paid sick leave, meaning that any time off for vaccination or recovery 
would result in lost wages for those who can least afford those losses 
(BLS, September 2021). The need for paid time off to receive 
vaccination is also particularly important for workers with 
disabilities and workers in rural areas because travel to and from 
vaccination sites may take more time or be more logistically difficult 
for those populations (National Safety Council, 2021).
    Paying workers for the time spent to receive vaccination and to 
recover from side effects has proven to be an effective method for 
increasing vaccination rates. In June 2021, KFF found that 
approximately 75% of employed adults surveyed who received paid time 
off to get the vaccine or to recover from side effects had received at 
least one dose of the vaccine compared to only 51% of those surveyed 
who did not receive paid time off from their employer (KFF, June 30, 
2021). KFF also found that employees who are provided paid time off and 
are encouraged by their employers to get vaccinated are more likely to 
get vaccinated, even after controlling for demographic characteristics 
that may impact vaccination uptake (KFF, June 30, 2021). Another KFF 
survey found that 28% of unvaccinated respondents who did not want to 
get the vaccine as soon as possible said that they would be more likely 
to obtain vaccination if their employer gave them paid time off to get 
vaccinated and recover from any side effects (KFF, May 6, 2021). KFF 
has also found that increasing access to paid leave for vaccination or 
recovery from side effects can also help further reduce disparities in 
vaccination by age and income (KFF, September 28, 2021).
    In a different survey, paid time off for vaccination and the 
recovery period post-vaccination was the single most-influential action 
for encouraging employee vaccination, with 75% of respondents 
indicating that such paid time off would significantly or moderately 
increase the likelihood that they would get vaccinated (Azimi et al., 
April 9, 2021). Another survey of nearly 9,000 service workers across 
large grocery, retail, food service, pharmacy, and delivery firms, 
found that vaccination rates were lower than other frontline workers 
who also regularly work in-person and indoors, and when employers 
supported and facilitated vaccination, such as through providing paid 
time off or paid sick leave for vaccination or for recovery from side 
effects, employee vaccination rates were higher than if no support was 
provided, and in May 2021, workers with paid sick leave were 15% more 
likely to have gotten the vaccine than workers without such leave 
(Bellew et al., June 2021).
    To address this barrier to vaccination, paragraph (f) requires 
employers to support COVID-19 vaccination by providing each employee 
with reasonable time, including up to four hours of paid time, to 
receive each primary vaccination dose, and reasonable time and paid 
sick leave to recover from side effects experienced following any 
primary vaccination dose. Providing this time is essential for all 
unvaccinated employees who are covered by this rule to ensure that they 
can receive primary vaccination dose(s) and recover from side effects 
without sacrificing pay or their jobs. In workplaces where employers 
implement a mandatory vaccination policy in accordance with paragraph 
(d)(1) of this rule, the requirements of paragraph (f) ensure that 
employees are able to comply with the mandatory vaccination policy 
without concern about missing work to do so. In workplaces where the 
employer opts out of implementing a mandatory vaccination policy in 
accordance with paragraph (d)(2), the requirements of paragraph (f) 
encourage employees to choose vaccination, and ensure that employees 
who choose to obtain vaccination, rather than be regularly tested for 
COVID-19 and wear a face covering in most situations when they work 
near others, are not penalized for making that choice.
    Paragraph (f)(1) requires employers to support COVID-19 vaccination 
for each employee by providing reasonable time to each employee during 
work hours for each of their primary vaccination dose(s), including up 
to four hours of paid time, at the employee's regular rate of pay, for 
the purposes of vaccination. Reasonable time may include, but is not 
limited to, time spent during work hours related to the vaccination 
appointment(s), such as registering, completing required paperwork, all 
time spent at the vaccination site (e.g., receiving the vaccination 
dose, post-vaccination monitoring by the vaccine provider), and time 
spent traveling to and from the location for vaccination (including 
travel to an off-site location (e.g., a pharmacy), or situations in 
which an employee working remotely (e.g., telework) or in an alternate 
location must travel to the workplace to receive the vaccine).
    Employers are not, however, obligated by this ETS to reimburse 
employees for transportation costs (e.g., gas money,



train/bus fare, etc.) incurred to receive the vaccination. This could 
include the costs of travel to an off-site vaccination location (e.g., 
a pharmacy) or travel from an alternate work location (e.g., telework) 
to the workplace to receive a vaccination dose.
    Because employers are required to provide reasonable time for 
vaccination during work hours, if an employee chooses to receive a 
primary vaccination dose outside of work hours, employers are not 
required to grant paid time to the employee for the time spent 
receiving the vaccine during non-work hours. However, even if employees 
receive a primary vaccination dose outside of work hours, employers 
must still afford them reasonable time and paid sick leave to recover 
from side effects that they experience during scheduled work time in 
accordance with paragraph (f)(2).
    An employer may make other efforts to facilitate vaccination of its 
employees by, for example, hosting a vaccine clinic at the workplace 
(e.g., mobile trailer) or partnering with another entity, such as a 
pharmacy or healthcare provider, so that employees can be vaccinated at 
the workplace or at an off-site location. If an employer chooses to 
make the vaccine available to its employees, it must support full 
vaccination (i.e., provide all doses in a primary vaccination, as 
applicable), and assure the availability of reasonable time and paid 
time to each employee to receive the full primary vaccination, and 
reasonable time and paid sick leave to recover from side effects that 
they may experience. Any additional costs incurred by the employer to 
bring vaccination on-site would be covered by the employer, though such 
an approach would likely reduce the amount of paid time needed for 
vaccine administration (but not side effects) because of reduced 
employee travel time.
    Paragraph (f)(1) specifies that the amount of paid time that an 
employer is required to provide each employee to receive each primary 
vaccination dose is capped at four hours. OSHA has determined that four 
hours would provide reasonable time for most employees to get each 
vaccination dose. Vaccines are widely available to the public at 
clinics, pharmacies, and other locations across the country (see CDC, 
October 8, 2021). Providing four hours of paid time to receive each 
primary vaccination dose is consistent with OSHA's presumption of the 
amount of time needed to receive a vaccination dose in the June 2021 
Healthcare ETS (86 FR 32598), and with the U.S. Office of Personnel 
Management's guidance to federal government agencies on the use of the 
emergency paid leave created for federal employees in the American 
Rescue Plan Act of 2021 (Public Law 117-2), which encouraged agencies 
to offer up to four hours of administrative leave per dose to cover 
time spent getting a vaccine dose, plus additional time if reasonably 
necessary, instead of having employees use emergency paid leave (OPM, 
April 29, 2021). OSHA expects that most employees will need less than 
four hours to receive a vaccination dose.
    The maximum of four hours of paid time that employers must provide 
under paragraph (f)(1)(ii) for the administration of each primary 
vaccination dose cannot be offset by any other leave that the employee 
has accrued, such as sick leave or vacation leave. OSHA is concerned 
that employees forced to use their sick leave or vacation leave for 
vaccination would have a disincentive to gaining the health protection 
of vaccination. Employers must pay employees for up to four hours of 
time at the employee's regular rate of pay. This may be achieved by 
paying for the time to be vaccinated as work hours for up to four 
hours. Requiring employers to pay for vaccine administration is 
consistent with OSHA's normal approach of requiring employers to bear 
the costs of compliance with safety and health standards.
    OSHA understands that employees may need much less than four hours 
to receive a primary vaccination dose, for example, if vaccinations are 
offered on-site. However, OSHA also understands that, in some 
circumstances, an employee may need more than four hours to receive a 
primary vaccination dose, in which case the additional time, as long as 
it is reasonable, would be considered unpaid but protected leave. The 
employer cannot terminate the employee if they use a reasonable amount 
of time to receive their primary vaccination doses. The employee may 
use other leave time that they have available (e.g., sick leave or 
vacation time) to cover the additional time needed to receive a 
vaccination dose that would otherwise be unpaid.
    Paragraph (f)(2) also requires employers to support COVID-19 
vaccination for each employee by providing reasonable time and paid 
sick leave to recover from side effects experienced following any 
primary vaccination dose to each employee for each dose. The paid sick 
leave can be in the form of an employee's accrued sick leave, if 
available. If the employee does not have available sick leave, leave 
must be provided for this purpose.
    Although some individuals experience no side effects from COVID-19 
vaccination doses, the CDC has identified a range of side effects that 
other individuals may experience following a vaccination dose (CDC, 
April 2, 2021; CDC, September 30, 2021). Side effects may affect 
individuals' ability to engage in daily activities, are typically mild-
to-moderate in severity, and usually go away in a few days. Common side 
effects include pain, redness, and swelling at the site of injection, 
and systemic side effects throughout the body, including tiredness, 
headache, muscle pain, chills, fever, and nausea. Side effects may be 
sufficiently severe to require the employee to take sick leave from 
work, but will rarely extend beyond a few days. One study found that 
``unanticipated paid administrative leave was only required for 4.9% 
and 19.79% of individuals after the first and second doses of vaccine, 
respectively'' (Levi et al., September 25, 2021). Employees would not 
typically be expected to need leave solely to address redness or 
swelling at the site of injection, but it is not uncommon for vaccine 
recipients to require some recovery time for many of the other side 
effects. The CDC notes, however, that cough, shortness of breath, runny 
nose, sore throat, or loss of taste or smell are not consistent with 
post-vaccination symptoms and instead may be symptoms of COVID-19 or 
another infection (CDC, April 2, 2021).
    If an employee already has accrued paid sick leave, an employer may 
require the employee to use that paid sick leave when recovering from 
side effects experienced following a primary vaccination dose. 
Additionally, if an employer does not specify between different types 
of leave (i.e., employees are granted only one type of leave), the 
employer may require employees to use that leave when recovering from 
vaccination side effects. If an employer provides employees with 
multiple types of leave, such as sick leave and vacation leave, the 
employer can only require employees to use the sick leave when 
recovering from vaccination side effects. Employers cannot require 
employees to use advanced sick leave to cover reasonable time needed to 
recover from vaccination side effects under paragraph (f)(2). An 
employer may not require an employee to accrue negative paid sick leave 
or borrow against future paid sick leave to recover from vaccination 
side effects. In other words, the employer cannot require an employee 
to go into the negative for paid sick leave if the employee does not 
have accrued paid


sick leave when they need to recover from side effects experienced 
following a primary vaccination dose. Neither the paid time required to 
receive any vaccine dose(s) nor the paid sick leave required to recover 
from side effects experienced following any vaccination dose are 
retroactive requirements for vaccine dose(s) received prior to the 
promulgation of this ETS.
    Paragraph (f)(2) requires employers to provide reasonable time and 
paid sick leave to employees to recover from side effects experienced 
following a primary vaccination dose, but does not specify the amount 
of paid sick leave that the employer is required to provide for that 
purpose. Employers may set a cap on the amount of paid sick leave 
available to employees to recover from any side effects, but the cap 
must be reasonable. CDC notes that although some people have no side 
effects, side effects, if experienced, should go away in a few days 
(CDC, September 30, 2021). Another study found that the average 
unanticipated paid administrative leave required by individuals 
experiencing side effects was around two days (1.66 days for the first 
dose and 1.39 days for the second dose) (Levi et al., September 25, 
2021). Generally, OSHA presumes that, if an employer makes available up 
to two days of paid sick leave per primary vaccination dose for side 
effects, the employer would be in compliance with this requirement. 
When setting the cap, an employer would not be expected to account for 
the unlikely possibility of the vaccination resulting in a prolonged 
illness in the vaccinated employee (e.g., a severe allergic reaction).
    OSHA is aware that other federal, state, or local laws, or 
collective bargaining agreements, may require employers to provide 
employees additional paid time for vaccination and/or paid sick leave 
to recover from vaccination side effects. Where such an overlap exists, 
the requirements of this standard are satisfied so long as the employer 
provides each employee reasonable time and four hours of paid time to 
receive each primary vaccination dose, and reasonable time and paid 
sick leave to recover from side effects experienced following a primary 
vaccination dose.

G. COVID-19 Testing for Employees Who Are Not Fully Vaccinated

    Paragraph (g) of this ETS addresses employers' obligations with 
respect to employees who are not fully vaccinated, including the 
requirement to ensure unvaccinated employees are tested for COVID-19. 
As explained in Need for the ETS (Section III.B. of this preamble), 
OSHA strongly prefers that employers implement written mandatory 
vaccination policies because that is the most effective and efficient 
workplace control available for preventing the spread of COVID-19. 
However, this ETS is also necessary to protect workers who remain 
unvaccinated through required regular testing, use of face coverings, 
and removal of infected employees from the workplace, and to protect 
other workers from the greater likelihood that unvaccinated workers may 
spread COVID-19 in the workplace. People who are unvaccinated are at 
increased risk of becoming infected with COVID-19 and are more likely 
to spread the disease when compared to people who


are fully vaccinated (CDC, September 15, 2021). Additionally, people 
who are unvaccinated are more likely to experience severe clinical 
outcomes if they become infected than people who are vaccinated (Lopez 
Bernal et al., July 21, 2021). Therefore, routine COVID-19 testing of 
unvaccinated employees is necessary to identify employees with COVID-19 
so they can be removed from the workplace to prevent transmission to 
other employees and to facilitate early medical intervention for 
infected employees when appropriate.
    Routine testing of unvaccinated employees is necessary regardless 
of whether the unvaccinated employees have symptoms because SARS-CoV-2 
infection is often attributable to asymptomatic and/or pre-symptomatic 
transmission (i.e., individuals who are not exhibiting symptoms) 
(Bender et al., February 18, 2021; Klompas, September 2021; Johansson 
et al., January 7, 2021; Byambasuren et al., December 11, 2020). 
Although less effective and efficient than vaccination, the CDC has 
recognized regularly testing unvaccinated employees for COVID-19 as a 
useful tool for identifying asymptomatic and/or pre-symptomatic 
infected individuals so that they can be isolated (CDC, May 4, 2021; 
CDC, October 7, 2021). In contrast, the CDC recommends that fully 
vaccinated employees with no symptoms and no known exposure should be 
exempt from routine testing programs (CDC, May 4, 2021). Additional 
information about the risks of COVID-19 transmission in vaccinated and 
unvaccinated workers is discussed in Grave Danger (Section III.A. of 
this preamble).
    Testing for COVID-19 can broadly be divided into two categories: 
diagnostic testing and screening testing. The purpose of diagnostic 
testing is to identify current infection when a person has signs or 
symptoms consistent with COVID-19, or when a person is asymptomatic but 
has recent known or suspected exposure to SARS-CoV-2. The information 
provided by diagnostic testing can be used by a healthcare provider to 
diagnose or treat a patient. The purpose of screening testing is to 
identify infected people who are asymptomatic and do not have known, 
suspected, or reported exposure to COVID-19. Screening testing helps to 
identify unknown cases both so that measures can be taken to prevent 
further transmission to others (e.g., removal from the workplace and 
home isolation) and also to allow infected, but asymptomatic, people to 
begin medical treatment, as appropriate, so they can better avoid the 
most severe outcomes of COVID-19 (e.g., high risk individuals seeking 
monoclonal antibody treatment or anti-viral medication). Although the 
testing required in paragraph (g)(1) of this ETS is screening testing, 
both screening and diagnostic testing can help prevent the spread of 
COVID-19. Paragraph (g) does not preclude additional diagnostic testing 
if an employee shows signs or symptoms consistent with COVID-19 or has 
recent known or suspected exposure to SARS-CoV-2.
    Both screening and diagnostic testing involve the use of viral 
COVID-19 tests to detect current infection, as opposed to antibody 
COVID-19 tests, which are used to detect whether a person has 
antibodies for COVID-19. A positive antibody test indicates someone has 
antibodies to SARS-CoV-2, the virus that causes COVID-19, which could 
either be the result of a prior infection with the virus or vaccination 
against COVID-19 (FDA, May 19, 2021; CDC, September 10, 2021). Viral 
tests for current infection fall into two categories: Nucleic acid 
amplification tests (NAATs) and antigen tests. The Food and Drug 
Administration (FDA) (October 6, 2021) has issued a number of Emergency 
Use Authorizations (EUAs) for viral COVID-19 tests. It is important to 
note that OSHA's definition of ``COVID-19 test'' requires that COVID-19 
tests be cleared, approved, or authorized by the FDA and administered 
in accordance with authorized instructions, with the noted exception of 
not allowing tests that are both self-administered and self-read by the 
employee unless observed by the employer or an authorized telehealth 
proctor. In this regard, OSHA recognizes that it is within FDA's 
authority and jurisdiction to help to assure the appropriate safety, 
efficacy, and accuracy of COVID-19 tests. The definition of ``COVID-19 
test'' has previously been discussed in the Summary and Explanation for 
paragraph (c) (Section VI.C. of this preamble). Additional information 
about the type of COVID-19 tests that would satisfy the requirements of 
paragraph (g) are available in that section of this preamble.
    As explained above, the most effective and efficient workplace 
control for preventing the spread of COVID-19 is vaccination and OSHA 
strongly prefers that employers implement written mandatory vaccination 
policies. However, where employers have unvaccinated employees, regular 
COVID-19 screening tests are necessary so infected employees can be 
identified and removed from the workplace to prevent workplace 
transmission and to facilitate early medical intervention, when 
appropriate. In addition to being more likely to become infected with 
COVID-19, people who are unvaccinated are more likely to experience 
severe clinical outcomes from COVID-19 than fully vaccinated people 
(see Grave Danger, Section III.A. of this preamble). In a recent CDC 
Morbidity and Mortality Weekly Report (MMWR) out of Los Angeles County, 
the SARS-CoV-2 infection rate among unvaccinated persons was 4.9 times 
and the hospitalization rate was 29.2 times the rates among fully 
vaccinated persons (Griffin et al., August 27, 2021). As explained 
below, regular screening testing of individuals for COVID-19 is an 
effective method of identifying asymptomatic and pre-symptomatic 
infections. Screening testing of unvaccinated employees is necessary 
because symptom and temperature checks will miss both asymptomatic and 
pre-symptomatic infections, which is a serious problem because pre-
symptomatic and asymptomatic transmission are significant drivers of 
the continued spread of COVID-19 (Johansson et al., January 7, 2021). 
Once infected employees are identified, they can be removed from the 
workplace, thereby reducing virus transmission to other employees.
    Several studies have indicated that the time from exposure to 
becoming contagious for COVID-19 is shorter than the time for symptoms 
to develop (incubation period), meaning that individuals can transmit 
SARS-CoV-2 before they begin to feel ill (i.e., pre-symptomatic 
transmission) (Nishiura et al., March 4, 2020; Tindale et al., June 22, 
2020). Pre-symptomatic individuals can transmit the virus to others 
before they know they are sick. These individuals should isolate but 
would not know to do so if they are unaware of their infection. It is 
also possible for individuals to be infected and subsequently transmit 
the virus without ever exhibiting symptoms. This is called asymptomatic 
transmission. A meta-analysis of 351 studies from January 1, 2020, to 
April 2, 2021, estimated that 42.8% of those infected with the SARS-
CoV-2 virus exhibited no symptoms at the time of testing and so had 
either asymptomatic or pre-symptomatic infections (Sah et al., August 
10, 2021). In another meta-analysis of studies, which included people 
of all ages at risk of contracting COVID-19 who were tested regardless 
of presence or absence of symptoms, seventeen percent of cases never 
developed symptoms during entire COVID-19 infection (i.e., asymptomatic 
infection). In those studies, a diagnosis was confirmed with


a positive result on a RT-PCR and all positive cases had a follow-up 
period of at least seven days to distinguish asymptomatic cases from 
pre-symptomatic cases (Byambasuren et al., December 11, 2020). In 
another study, researchers used a decision analytical model to assess 
the proportion of SARS-CoV-2 transmission from pre-symptomatic, never 
symptomatic, and symptomatic individuals in the community. Based on 
their modeling, they predicted that 59% of transmission came from 
asymptomatic transmission, including 35% from pre-symptomatic 
individuals and 24% from individuals who never develop symptoms 
(Johansson et al., January 7, 2021).
    The existence of pre-symptomatic and asymptomatic infections pose 
serious challenges to containing the spread of SARS-CoV-2. Although the 
risk of asymptomatic transmission is 42% lower than from symptomatic 
COVID-19 patients (Byambasuren et al., December 11, 2020), asymptomatic 
transmission may result in more transmissions than symptomatic cases 
because asymptomatic persons are less likely to be aware of their 
infection and can unknowingly continue to spread the disease to others 
(Sah et al., August 10, 2021). The challenge of containing pre-
symptomatic and asymptomatic SARS-CoV-2 transmission is amplified among 
unvaccinated individuals because, as explained above, they are more 
likely to become infected with COVID-19 in the first place.
    Because unvaccinated employees are at higher risk of COVID-19 
infection and COVID-19 transmission among individuals without symptoms 
is a significant driver of the spread of COVID-19, OSHA has determined 
it is necessary to prevent the pre-symptomatic and asymptomatic 
transmission of COVID-19 from unvaccinated workers, through a 
requirement for weekly screening testing. Screening testing with 
antigen tests is a rapidly evolving and important tool that can be used 
to reduce the spread of SARS-CoV-2 in the workplace, particularly when 
coupled with other COVID-19 prevention and control measures (e.g., 
workplace removal of infected persons, proper use of face coverings) 
(Schulte et al., May 19, 2021). The CDC recommends screening testing of 
unvaccinated asymptomatic workers as a useful tool to detect COVID-19 
and stop transmission quickly. Screening testing is particularly useful 
in areas with moderate to high community transmission of COVID-19, 
which is currently the overwhelming majority of the United States (CDC, 
October 7, 2021). In a study with a well-defined population of SARS-
CoV-2 infected individuals, researchers found that frequent testing 
(i.e., at least twice per week) maximizes the likelihood of detecting 
infected individuals. However, even when used weekly, rapid antigen 
tests still had a 76% probability of detection (i.e., weekly rapid 
antigen tests correctly identified 76% of true positive infected COVID-
19 individuals) (Smith et al., September 15, 2021). By identifying pre-
symptomatic and asymptomatic unvaccinated employees, employers can 
remove them from the workplace to prevent those employees from 
spreading SARS-CoV-2 to other employees. More information about the 
removal requirements in this ETS is available in the Summary and 
Explanation for paragraph (h) (Section VI.H. of this preamble).
    Since the incubation period for COVID-19 can be up to 14 days, the 
CDC recommends that screening testing be conducted at least weekly in 
non-healthcare workplaces (CDC, October 7, 2021; CDC, May 4, 2021). 
Other researchers also recognize the effectiveness of weekly screening 
testing to control surges of COVID-19 infections (Larremore, January 1, 
2021). Consequently, in workplaces with unvaccinated employees, OSHA 
has set the minimum frequency of testing unvaccinated workers at seven 
days because the agency expects that it will be effective in slowing 
the spread of COVID-19 in those workplaces, when used in tandem with 
face coverings (paragraph (i)) and removal of infected individuals 
(paragraph (h)). OSHA emphasizes that each of these infection controls 
provides some protection from COVID-19 by itself, but that they work 
best when used together, layering their protective impact to boost 
overall effectiveness. Although some studies have shown that more 
regular screening testing (e.g., twice weekly) would identify even more 
cases, OSHA has decided to require testing only on a weekly basis. This 
is in line with the CDC recommendations, and as noted above the 
evidence shows that this frequency is effective in detecting 
asymptomatic and pre-symptomatic cases. A more frequent testing 
schedule would result in significant additional costs, and OSHA is 
hesitant to impose these costs and depart from CDC recommendations 
without a fuller record generated through the benefit of notice and 
comment rulemaking. OSHA seeks comment on this issue. Nonetheless, it 
should be noted that nothing in this rule prevents screening testing 
from being conducted more frequently based on factors such as the level 
of community transmission, workplace experience with outbreaks, and 
type of workplace (e.g., specific workplace factors such as high volume 
retail or critical infrastructure sector).
    Early detection of COVID-19-positive employees through screening 
testing of unvaccinated employees also facilitates early medical 
intervention, when appropriate, to avoid the most severe health 
outcomes associated with COVID-19. Early effective treatment of disease 
can help avert progression to more serious illness, especially for 
patients at high risk of disease progression and severe illness, with 
the additional benefit of reducing the burden on healthcare systems 
(CDC, December 4, 2021). For example, anti-SARS-CoV-2 monoclonal 
antibodies have been shown to reduce the risk of hospitalization and 
death in the outpatient setting in those with mild to moderate COVID-19 
symptoms and certain risk factors for disease progression. Treatment 
should be started as soon as possible after the patient receives a 
positive result on a COVID-19 test and within 10 days of symptom onset 
(NIH, September 24, 2021). Any COVID-19 medical treatment should be 
used in accordance with a licensed healthcare provider. The screening 
tests required by this rule will facilitate such treatment.
    Pursuant to paragraph (g)(1)(i), covered employers must ensure that 
each employee who is not fully vaccinated and reports at least once 
every seven days to a workplace where other individuals (e.g., 
coworkers, customers) are present: (A) Is tested for COVID-19 at least 
once every seven days; and (B) provides documentation of the most 
recent COVID-19 test result to the employer no later than the 7th day 
following the date on which the employee last provided a test result. 
Employers must ensure these unvaccinated employees are tested at least 
once every seven calendar days, regardless of their work schedule. For 
example, an unvaccinated part-time employee who is scheduled to work 
only every Monday and Tuesday must still be tested at least once every 
seven days. Because employees must provide documentation of their most 
recent COVID-19 test results to their employers no later than the 7th 
day following the date on which they last provided a test result, 
employees may want to set a schedule for their testing (e.g., get a 
COVID-19 test every Wednesday). A consistent testing day may help 
employees ensure their documentation is provided every seven calendar 
days.


    Paragraph (g)(1)(ii) addresses situations where an employee does 
not report to a workplace where other individuals, such as coworkers or 
customers, are present during a period of seven or more days (e.g., 
when an employee is teleworking for an extended period of time). In 
such cases, the employer must ensure the employee is tested for COVID-
19 within seven days prior to returning to the workplace and provides 
documentation of that test result to the employer upon return to the 
workplace. For example, if an unvaccinated office employee has been 
teleworking for two weeks but must report to the office, where other 
employees will be present (e.g., coworkers, security officers, mailroom 
workers), on a specific Monday to copy and fax documents, that employee 
must receive a COVID-19 test within the seven days prior to the Monday 
and provide documentation of that test result to the employer upon 
return to the workplace. The employee's test must occur within the 
seven days before the Monday the employee is scheduled to report to the 
office, but it also must happen early enough to allow time for the 
results to be received before returning to the workplace. Similarly, 
unvaccinated new hires would need to be tested for COVID-19 within 
seven days prior to reporting to a workplace where other employees will 
be present and provide documentation of their test results no later 
than arrival on their first day of work. Since point-of-care testing 
that uses an antigen test allows for results within minutes, OSHA does 
not expect that scheduling tests or providing results to employers will 
be an impediment.
    OSHA chose the seven-day period for employees returning to work 
after more than a week away from the workplace based on the evidence 
noted above about the effectiveness of testing at seven-day intervals. 
While it considered using a shorter time period in this situation, OSHA 
concluded that it would be less confusing for employers to use a 
uniform time period for both situations. OSHA was concerned that 
requiring different time periods in the two situations would cause 
confusion among both employees and supervisors implementing the program 
that would undermine the effectiveness of the testing scheme. OSHA 
seeks comment on this issue.
    An employer has some discretion regarding how to satisfy its 
obligations under paragraph (g)(1), but those policies and procedures 
must be detailed in the employer's written policy pursuant to paragraph 
(d)(2) of this ETS. For example, the employer must specify how testing 
will be conducted (e.g., testing provided by the employer at the 
workplace, employees independently scheduling tests at point-of-care 
locations, etc.). The employer must also specify in their policy how 
employees should provide their COVID-19 test results to the employer 
(e.g., an online portal, to the human resources department). The 
Summary and Explanation for paragraph (d) (Section VI.D. of this 
preamble) provides additional information regarding the requirements of 
paragraph (d)(2) of this ETS. Test results given to the employer must 
contain information that identifies the worker (i.e., full name plus at 
least one other identifier, such as date of birth), the specimen 
collection date, the type of test, the entity issuing the result (e.g., 
laboratory, healthcare entity), and the test result.
    If an employer is notified that an employee has a positive 
screening test, the employer must remove that employee from the 
workplace pursuant to paragraph (h)(2) of this ETS. The employee should 
quarantine and the employer must not allow the employee to return to 
the workplace until they meet the requirements in paragraphs (h)(2)(i) 
through (iii). More discussion of employee notification to their 
employer of a COVID-19 positive status and removal requirements is 
available in the Summary and Explanation for paragraph (h) (Section 
VI.H. of this preamble).
    OSHA expects that most screening testing will be antigen testing 
that is conducted at point-of-care locations due to the reduced cost 
and faster processing time when compared to NAAT testing in 
laboratories. Most NAATs need to be processed in a laboratory with 
variable time to results (approximately 1-2 days). In contrast, most 
antigen tests can be processed at the point of care with results 
available in about 15-30 minutes (CDC, October 7, 2021). Rapid point-
of-care tests are administered in various settings, such as: Physician 
offices, urgent care facilities, pharmacies, school health clinics, 
workplace health clinics, long-term care facilities and nursing homes, 
and at temporary locations, such as drive-through sites managed by 
local organizations. As explained above, COVID-19 tests that are both 
self-administered and self-read do not meet the definition of ``COVID-
19 test'' in this ETS (unless observed by the employer or an authorized 
telehealth proctor) and therefore do not satisfy the testing 
requirements of paragraph (g).
    Because antigen testing in point-of-care locations will typically 
produce results within minutes, the use of antigen testing should not 
result in an inability to provide the employer with test results in a 
timely fashion. However, the agency recognizes that where the employee 
or employer uses an off-site laboratory for testing, there may be 
delays beyond the employee's or employer's control. In the event that 
there is a delay in the laboratory reporting results and the employer 
permits the employee to continue working, OSHA will look at the pattern 
and practice of the individual employee or the employer's testing 
verification process and consider refraining from enforcement where the 
facts show good faith in attempting to comply with the standard.
    OSHA has determined that employers may use pooling procedures to 
satisfy the requirements of screening testing under paragraph (g)(1). 
Pooling (also referred to as pool testing or pooled testing) means 
combining the same type of specimen from several people and conducting 
one laboratory test on the combined pool of specimens to detect SARS-
CoV-2 (e.g., four samples may be tested together, using only the 
resources needed for a single test). The advantages of pooling include 
preserving testing resources, reducing the amount of time required to 
test large numbers of specimens (increasing throughput), and lowering 
the overall cost of testing (CDC, June 30, 2021).
    If pooling procedures are used and a pooled test result comes back 
negative, then all the specimens can be presumed negative with the 
single test. In other words, all of the employees who provided 
specimens for that pool test can be assumed to have a negative test 
result for SARS-CoV-2 infection. Therefore, documentation of the 
negative pooled test result would satisfy the paragraph (g)(1) 
documentation requirement for each employee in the pool and no 
additional testing is necessary. However, if the pooled test result is 
positive, immediate additional testing would be necessary to determine 
which employees are positive or negative. Each of the original 
specimens collected in the pool must be tested individually to 
determine which specimen(s) is (are) positive. If original specimens 
from the workers in a pooled test with a positive result are 
insufficient to be subsequently tested individually, those workers in 
the positive pool would need to be immediately re-swabbed and tested. 
The individual employee test results would be necessary to satisfy the 
employee documentation requirements of paragraph (g)(1). Where pooled 
testing is used (in accordance with paragraph (g)(1)), CDC and FDA 
procedures and


recommendations for implementing screening pooled tests should be 
followed (CDC, June 30, 2021; FDA, August 24, 2020). OSHA notes that 
only some tests are authorized for pooled testing, and should be 
performed per the authorization.
    In a note to paragraph (g)(1), OSHA explains that this section does 
not require the employer to pay for any costs associated with testing. 
As explained in Pertinent Legal Authority, Section II. of this 
preamble, the OSH Act authorizes OSHA to require employers to bear the 
costs of compliance with occupational safety and health standards, but 
OSHA has discretion to decide whether to impose certain costs--such as 
those related to medical examinations or other tests--on employers 
``[w]here [it determines that such costs are] appropriate.'' 29 U.S.C. 
655(b)(7). OSHA has commonly required employers to bear the costs of 
compliance with standards as a cost of doing business, including 
requiring employers to bear the costs of medical examinations and 
procedures (see, e.g., 29 CFR 1910.1018(n)(1)(i) (inorganic arsenic 
standard requires employers to ensure that medical examinations and 
procedures are provided ``without cost to the employee''); see also 
United Steelworkers, 647 F.2d at 1229-31 (discussing Lead standard's 
medical removal provisions and OSHA's authority for imposing cost of 
medical removal on employers)). Requiring employers to bear the costs 
of compliance makes it more likely that employees will take advantage 
of workplace protections (see 86 FR 32605). For example, employees are 
more likely to use personal protective equipment (PPE) when employers 
provide the PPE to their employees at no cost (see 72 FR 64342, 64344).
    In this ETS, OSHA has largely required employers to bear the costs 
of compliance, including the typical costs associated with vaccination, 
but has determined that it would not be appropriate to impose on 
employers any costs associated with COVID-19 testing for employees who 
choose not to be vaccinated. As explained in Need for the ETS, Section 
III.B. of this preamble, this ETS is designed to strongly encourage 
vaccination because vaccination is the most efficient and effective 
control for protecting unvaccinated workers from the grave danger posed 
by COVID-19. COVID-19 testing is only required under the ETS where an 
employee has made an individual choice to forgo vaccination and pursue 
a less protective option. Given the superior protectiveness of 
vaccination, and OSHA's intent for this ETS to strongly encourage 
vaccination, requiring employers to bear the costs of COVID-19 testing 
would be counter-productive. As mentioned above, requiring employers to 
pay for workplace protections makes it more likely that employees will 
take advantage of that protection, and in this ETS, OSHA intends to 
strongly encourage employees to choose vaccination, not regular COVID-
19 testing. Because employees who choose to remain unvaccinated will 
generally be required to pay for their own COVID-19 testing, this 
standard creates a financial incentive for those employees to become 
fully vaccinated and avoid that cost.
    Although this ETS does not require employers to pay for testing, 
employer payment for testing may be required by other laws, 
regulations, or collective bargaining agreements or other collectively 
negotiated agreements. This section also does not prohibit the employer 
from paying for costs associated with testing required by paragraph 
(g)(1) of this section. Otherwise, the agency leaves the decision 
regarding who pays for the testing to the employer. Because OSHA does 
not specify who pays for the testing, OSHA expects that some workers 
and/or their representatives will negotiate the terms of payment. OSHA 
has also considered that some employers may choose to pay for some or 
all of the costs of testing as an inducement to keep employees in a 
tight labor market. Other employers may choose to put the full cost of 
testing on employees in recognition of the employee's decision not to 
become fully vaccinated. It is also possible that some employers may be 
required to cover the cost of testing for employees pursuant to other 
laws or regulations. OSHA notes, for instance, that in certain 
circumstances, the employer may be required, under the Fair Labor 
Standards Act, to pay for the time it takes an employee to be tested 
(e.g., if employee testing is conducted in the middle of a work shift). 
The subject of payment for the costs associated with testing pursuant 
to other laws or regulations not associated with the OSH Act is beyond 
OSHA's authority and jurisdiction. As explained in a note to paragraph 
(d) of this ETS, under various anti-discrimination laws, workers who 
cannot be tested because of a sincerely held religious belief may ask 
for a reasonable accommodation from their employer. For more 
information about evaluating requests for reasonable accommodation for 
a sincerely held religious belief, employers should consult the Equal 
Employment Opportunity Commission's website: https://www.eeoc.gov/wysk/what-you-should-know-about-covid-19-and-ada-rehabilitation-act-and-other-eeo-laws.
    Pursuant to paragraph (g)(2), if an employee does not provide the 
result of a COVID-19 test as required by paragraph (g)(1), the employer 
must keep the employee removed from the workplace until the employee 
provides a test result. This provision is imperative because workers 
with asymptomatic or pre-symptomatic SARS-CoV-2 infection are 
significant contributors to COVID-19 transmission, and screening 
testing will help to identify and remove those individuals from the 
workplace. Employees providing accurate and weekly test results to 
their employer is of utmost importance for preventing and reducing the 
transmission of COVID-19 in the workplace.
    Paragraph (g)(3) provides that when an employee has received a 
positive COVID-19 test, or has been diagnosed with COVID-19 by a 
licensed healthcare provider, the employer must not require that 
employee to undergo COVID-19 testing for 90 days following the date of 
their positive test or diagnosis. This provision is specifically 
intended to prohibit screening testing for 90 days because of the high 
likelihood of false positive results that do not indicate active 
infection but are rather a reflection of past infection. Studies of 
patients who were hospitalized and recovered indicate that SARS-CoV-2 
RNA can be detected in upper respiratory tract specimens for up to 
three months (90 days) after symptom onset (CDC, August 2, 2021; CDC, 
September 14, 2021). If employees were to be subjected to screening 
tests in such a situation it would both undermine the confidence in the 
COVID-19 screening tests and could result in a harm to the worker of 
being unnecessarily removed from the workplace and subjected to the 
additional burden of unnecessary tests. Where employers implement a 
vaccination policy that allows employees to choose to provide proof of 
regular testing and wear a face covering rather than getting 
vaccinated, the employer's policy and procedures to implement this 
temporary suspension of testing must be included in their written 
workplace policy as required by paragraph (d)(2) of this ETS.
    Paragraph (g)(4) provides that the employer must maintain a record 
of each test result required to be provided by each employee under 
paragraph (g)(1) of this ETS or obtained during tests conducted by the 
employer. These records must be maintained in


accordance with 29 CFR 1910.1020 as an employee medical record and must 
not be disclosed except as required by this ETS or other federal law. 
However, these records are not subject to the retention requirements of 
29 CFR 1910.1020(d)(1)(i) (Employee medical records), but must be 
maintained and preserved while this ETS remains in effect.
    Additionally, paragraph (l) of this ETS includes specific 
timeframes for providing access to records, including the COVID-19 test 
results required by paragraph (g)(1). As a result, the timeframes for 
providing access to employee medical records in 29 CFR 1910.1020(e) do 
not apply. Instead, when providing access to an employee, anyone with 
written authorized consent from that employee, and OSHA, employers must 
follow the access timeframes set forth in paragraph (l) of this ETS. 
The Summary and Explanation for paragraph (l) (Section VI.L. of this 
preamble) contains additional information about accessing records 
gathered pursuant to paragraph (g)(1).
    Finally, while the access timeframes in 29 CFR 1910.1020(e) and 
retention requirements of 29 CFR 1910.1020(d)(1)(i) do not apply to 
test result records required by this ETS, the other provisions in 29 
CFR 1910.1020 do apply. For example, 29 CFR 1910.1020(h) includes 
requirements for the transfer of employee medical records when an 
employer ceases to do business. Like the vaccine records required by 
paragraph (e)(4) of this ETS, and because they concern the health 
status of an employee, test result records required by paragraph (g)(1) 
are employee medical records for purposes of 29 CFR 1910.1020. These 
test result records contain personally identifiable medical information 
and must be maintained in a confidential manner. The Summary and 
Explanation for paragraph (e) (Section VI.E. of this preamble) contains 
additional information about the interplay between this ETS and OSHA's 
regulation at 29 CFR 1910.1020.

H. Employee Notification to Employer of a Positive COVID-19 Test and 
Removal

    Employers can substantially reduce disease transmission in the 
workplace by removing employees who are confirmed to have COVID-19 
based on a COVID-19 test or diagnosis by a healthcare provider. It is 
necessary that employees who are confirmed to have COVID-19 be removed 
from the workplace to prevent transmission to other employees. Several 
studies have focused on the impact of isolating persons with COVID-19 
from others during their likely known infectious period, and those 
studies show that isolation is a strategy that reduces the transmission 
of infections. For example, Kucharski et al. (2020) found that 
transmission of SARS-CoV-2 would decrease by 29% with self-isolation 
within the household, which would extend to 37% if the entire household 
quarantined. Similarly, Wells et al. (2021) found that isolation of 
individuals at symptom onset would decrease the reproductive rate (R0) 
of COVID-19 from 2.5 to 1.6. Lastly, Moghadas et al. (2020) reported 
results that highlight the role of silent transmission, from a 
combination of the pre-symptomatic stage and asymptomatic infections, 
as the primary driver of COVID-19 outbreaks and underscore the need for 
mitigation strategies, including those that detect and isolate 
infectious individuals prior to the onset of symptoms. Isolating 
contagious employees from their co-workers can prevent further spread 
at the workplace and safeguard the health of other employees.
    Paragraph (h) provides that employers must require each employee to 
promptly notify the employer when the employee receives a positive 
COVID-19 test or is diagnosed with COVID-19 by a licensed healthcare 
provider. This notification must occur regardless of employee 
vaccination status. As discussed in Grave Danger (Section III.A. of 
this preamble), exposure to SARS-CoV-2 in the workplace presents a 
grave danger to employees; removing those who are confirmed to have 
COVID-19 from the workplace mitigates that grave danger. This is true 
even for fully vaccinated employees since they also have the potential 
to transmit COVID-19 to other individuals, including other employees. 
Because the goal of this ETS, and the notification requirements in this 
paragraph, is to reduce transmission of COVID-19 in the workplace, 
employees are required to notify the employer of any COVID-19 positive 
test or diagnosis that they receive, not just positive results that are 
received from testing required under paragraph (g) of this ETS.
    Paragraph (h)(1) states that the employer must require each 
employee who is COVID-19 positive to notify the employer of their 
COVID-19 test result or diagnosis ``promptly.'' For employees who are 
not at the workplace when they receive a positive COVID-19 test result 
or diagnosis, ``promptly'' notifying the employer means notifying the 
employer as soon as practicable before the employee is scheduled to 
start their shift or return to work. In the event that the employee is 
in the workplace when they receive a positive COVID-19 test result or 
diagnosis of COVID-19, ``promptly'' notifying the employer means 
notifying the employer as soon as safely possible while avoiding 
exposing any other individuals in the workplace.
    The employer should establish notification procedures and inform 
employees about these procedures (see paragraph (j)(1)), so that 
employees are aware of the appropriate method for providing this 
notification to their employer. These notification procedures can be 
based on the employer's current protocols for employees to notify the 
employer if they are not able to come to work or need to leave work 
because of illness or injury. However the employer chooses to implement 
its notification procedures, it must ensure that an employee 
notification of a positive COVID-19 test or diagnoses results in the 
employee's immediate removal from the workplace, as required under 
paragraph (h)(2). For example, the employer may require employees to 
report any positive COVID-19 test or diagnosis to a company supervisor 
with the authority to temporarily remove the employee from the 
workplace. If an employer takes all steps required under this paragraph 
but an employee fails to report required information, the ETS does not 
dictate that any disciplinary action be taken against the employee. If 
an employer is cited by OSHA under this provision under such 
circumstances, the employer is entitled to contest the citation if it 
can establish an employee misconduct defense in accordance with 
applicable case law.
    The notification requirement in paragraph (h)(1) is an important 
measure to ensure employers can take adequate steps to protect their 
employees from the hazard of COVID-19 because it is connected to a 
parallel requirement in paragraph (h)(2) to remove, from the workplace, 
any employee who receives a positive COVID-19 test or is diagnosed with 
COVID-19. It is important to remove employees who test positive or are 
diagnosed with COVID-19 from the workplace as soon as possible to 
prevent the transmission of COVID-19 to other employees. Therefore, the 
requirement that employees promptly inform their employer of a positive 
COVID-19 test result or COVID-19 diagnosis is necessary because this 
information allows the employer to take actions to protect other 
employees, including most critically by removing employees whose 
illness poses a direct threat of infection to other employees in the 
workplace.
    Paragraph (h)(2) requires employers to immediately remove from the 
workplace any employee, regardless of vaccination status, who receives 
a positive COVID-19 test or is diagnosed with COVID-19 by a licensed 
healthcare provider. OSHA determined that directing an employee who 
tests positive or is diagnosed with COVID-19 to stay home until return 
to work criteria are achieved is critical to preventing the 
transmission of COVID-19 in the workplace. Similar to the notification 
required in paragraph (h)(1), this removal must occur regardless of 
employee vaccination status since someone who is fully vaccinated can 
still transmit COVID-19 to others, including other employees (see Grave 
Danger, Section III.A. of this preamble).
    OSHA notes that, in most circumstances, any positive COVID-19 test 
would result in removal. However, this is not necessarily the case 
where an employer uses pooled COVID-19 testing, a method where one 
laboratory test is conducted using the specimens of several people to 
detect the virus that causes COVID-19 (CDC, June 30, 2021). If an 
employer conducts pooled testing for COVID-19, a positive pooled test 
result would trigger a need to immediately re-test those employees in 
the pool using an individual COVID-19 test because the positive pooled 
result would not satisfy the requirements of paragraph (g). Only those 
employees who test positive on their individual re-test would need to 
be removed from the workplace.
    OSHA intends ``removal'' under paragraph (h)(2) to refer only to 
the temporary removal from the workplace of an employee while that 
employee is infectious. The requirement in paragraph (h)(2) to 
temporarily remove a COVID-19 positive employee from the workplace does 
not mean permanent removal of an employee from their position. Any time 
an employee is


required to be removed from the workplace under paragraph (h)(2) of 
this section, the employer can require the employee to work remotely or 
in isolation if suitable work is available and if the employee is not 
too ill to work. In cases where working remotely or in isolation is not 
possible, OSHA encourages employers to consider flexible and creative 
solutions, such as a temporary reassignment to a different position 
that can be performed by telework. However, if an employee is too ill 
to work, remote work should not be required, and sick leave or other 
leave should be made available as consistent with the employer's 
general policies and practices, and as may be required under applicable 
laws.
    After an employee has been removed from the workplace as required 
by paragraph (h)(2), the employer must ensure that they do not return 
to the workplace until the employee meets one of three criteria 
outlined in paragraphs (h)(2)(i) through (h)(2)(iii). The purpose of 
these provisions is to ensure that an employee who has COVID-19 does 
not return to work until the risk that they will transmit the disease 
to others in the workplace has been minimized. Each of these provisions 
is based on the best scientific evidence available on when a person 
with COVID-19 is no longer likely to transmit the virus.
    Under paragraph (h)(2)(i), the employee can return to work if they 
receive a negative result on a COVID-19 nucleic acid amplification test 
(NAAT) following a positive result on a COVID-19 antigen test (the most 
common screening test). There is a small possibility for employees to 
receive false positive test results when conducting regular screening 
with an antigen test. Positive results are usually highly accurate at 
moderate-to-high peak viral load, but false positives can occur, 
depending on the course of infection (FDA, April 2021). OSHA recognizes 
that an employee might choose to seek a NAAT test for confirmatory 
testing. NAATs are considered the ``gold standard'' for clinical 
diagnosis of SARS-CoV-2 and may have a higher sensitivity (i.e., 
ability to correctly generate a positive result) than antigen tests 
(CDC, September 9, 2021). If an employee tested positive for COVID-19 
via an antigen test, but then received follow-up confirmatory testing 
via a NAAT and the NAAT was negative, the positive antigen test can be 
considered a false positive and the employee can return to work (CDC, 
September 9, 2021). For a more detailed discussion of COVID-19 tests, 
see the Summary and Explanation for paragraph (c) (Section VI.C. of 
this preamble).
    The employee may also return to work if they meet the return to 
work criteria in CDC's ``Isolation Guidance'' (incorporated by 
reference, Sec.  1910.509) (CDC, February 18, 2021) as described in 
paragraph (h)(2)(ii). CDC's guidance states that a COVID-19 positive 
person can stop isolating when three criteria are met: (1) At least ten 
days have passed since the first appearance of the person's symptoms; 
(2) the person has gone at least 24 hours without a fever (without the 
use of fever-reducing medication); and (3) the person's other symptoms 
of COVID-19 are improving (excluding loss of taste and smell). If a 
person has tested positive but never experiences symptoms, then the 
person can stop isolating after ten days from the date of their 
positive test. These recommendations are based on scientific evidence 
reviewed by CDC, which indicates that levels of viral RNA in upper 
respiratory tract samples begin decreasing after the onset of symptoms 
(CDC, September 14, 2021). The rationale for including CDC's 
``Isolation Guidance'' in the ETS was addressed in detail in Need for 
Specific Provisions in the agency's prior rulemaking on 1910.502 (see 
86 FR 32376, 32455).
    Finally, the employee may return to work, per paragraph 
(h)(2)(iii), if the employee receives a return-to-work recommendation 
from a licensed healthcare provider. The appropriate duration of 
removal from work for any given individual may differ depending on 
factors such as disease severity or the health of the employee's immune 
system. For this reason, the ETS permits employers to make decisions 
about an employee's return to work in accordance with guidance from a 
licensed healthcare provider (who would be better acquainted with a 
particular employee's condition). If a licensed healthcare provider 
recommends a longer period of isolation for a particular employee than 
the CDC's ``Isolation Guidance'' would otherwise recommend, then the 
employer would need to abide by that longer period rather than 
returning the employee to work after ten days.
    OSHA's removal requirements as outlined in paragraph (h)(2) are 
intended to set the floor for what is required; however, OSHA 
encourages employers who are able to do so to have a more robust 
program of medical removal, as indeed some employers have already done. 
In addition to removal from the workplace based on a positive COVID-19 
test or diagnosis of COVID-19, employers may consider removal based on 
COVID-19 symptoms or certain exposure or close contacts employees have 
had outside of the workplace. Similarly, employers may consider 
removing employees from the workplace if the employer learns that the 
employee was notified by a state or local public health authority to 
quarantine or isolate; the employer might even be contacted by such an 
authority directly. Although this ETS does not require removal from the 
workplace in those situations, the employer might choose to remove 
employees from the workplace, above and beyond what is required by this 
ETS.
    Finally, the note to paragraph (h)(2) clarifies that this ETS does 
not require employers to provide paid time to any employee for removal 
as a result of a positive COVID-19 test or diagnosis of COVID-19; 
however, paid time may be required by other laws, regulations, or 
collective bargaining agreements or other collectively negotiated 
agreements. On the other hand, the ETS does not preclude employers from 
choosing to pay employees for time required for removal under this 
standard. Additionally, employers should allow their employees to make 
use of any accrued leave in accordance with the employer's policies and 
practices on use of leave. This provision, while not placing the burden 
on the employer to provide paid time, should not be read as depriving 
employees of the benefits they are normally entitled to as part of 
their employment.
    Because it does not require employers to provide paid time to 
employees who are removed for a positive COVID-19 test or diagnosis of 
COVID-19, this ETS differs from OSHA's COVID-19 Healthcare ETS, which 
applies to employees in the healthcare industry who are expected to be 
exposed to COVID-19, and requires paid medical removal protection 
benefits (Sec.  1910.502(l)(5)) for most employees. This difference 
reflects the structure and focus of this ETS relative to the Healthcare 
ETS. The Healthcare ETS requires employees to report symptoms of COVID-
19 to their employers, as well as positive COVID-19 tests or diagnoses 
(see Sec.  1910.502(l)(2)), but does not require employees to be 
regularly tested for COVID-19. A primary function of the payment for 
medical removal in that standard is, therefore, to remove the potential 
for financial disincentives that might deter employees from reporting 
any signs or symptoms of COVID-19 that they experience. Because this 
ETS already requires testing for unvaccinated workers, which should 
result in employers learning of cases of COVID-19 in unvaccinated 
workers, and does not otherwise require


employees to report signs and symptoms of COVID-19 to their employers, 
OSHA found that requiring employer payment for removal was not 
necessary in this standard.
    As the note to paragraph (h) indicates, the employer may be 
required to follow other laws or regulations that would require paid 
medical removal. For example, if an employee covered by this ETS 
believes they were exposed to COVID-19 in the workplace and then tested 
positive, that employee may be entitled to workers' compensation 
benefits. Workers' compensation is a system already in place to provide 
benefits to employees who get sick or injured on the job from 
occupational disease or a work-related injury. Some states have 
expressly clarified or expanded their workers compensation rules to 
allow for COVID-19 claims during the pandemic (see, e.g., Industrial 
Commission of Arizona, May 15, 2020; Connecticut Executive Order No. 
7JJJ, July 24, 2020; Minn. Stat. Ann. Sec.  176.011 Subd. (15)(f), 
2020)).
    Finally, the ETS does not contain specific requirements under this 
paragraph for the employer to establish or maintain records of employee 
notifications of a positive COVID-19 test or diagnosis of COVID-19 by a 
licensed healthcare provider. However, should an employer determine 
that a reported case of COVID-19 is work-related, the employer must 
continue to record that information on the OSHA Forms 300, 300A, and 
301, or on equivalent forms, if required to do so under 29 CFR part 
1904. This also includes confirmed cases of COVID-19 identified under 
paragraph (h) that an employer determines are work-related. Under 29 
CFR part 1904, COVID-19 is a recordable illness and employers are 
responsible for recording cases of COVID-19 if: (1) The case is a 
confirmed case of COVID-19 as defined by the Centers for Disease 
Control and Prevention (CDC); (2) the case is work-related as defined 
by 29 CFR part 1904.5; and (3) the case involves one or more of the 
general recording criteria in set forth in 29 CFR part 1904.7 (e.g., 
medical treatment beyond first aid, days away from work). Under 29 CFR 
part 1904, employers must generally provide access to the 300 log to 
employees, former employees, and their representatives with the names 
of injured or ill employees included on the form. If, however, the 
employee requests that their name not be entered on the 300 log, the 
employer must treat their illness as a privacy concern case and may not 
enter their name on the log (see 29 CFR 1904.29(b)(6), (b)(7)(vi)).

I. Face Coverings

    Paragraph (i) of this standard addresses the use of face coverings. 
As previously discussed in Grave Danger (Section III.A. of this 
preamble), COVID-19 spreads when an infected person breathes out 
droplets and very small particles that contain the virus. These 
droplets and particles can be breathed in by other people or land on 
their eyes, noses, or mouth. Face coverings reduce the risk of droplet 
transmission of COVID-19. The CDC recommends that people who are not 
fully vaccinated wear a face covering (e.g., a mask) in indoor public 
places. (CDC, July 14, 2021). Additional discussion on the efficacy of 
face coverings is provided below.
    Face coverings are simple bi-directional barriers that tend to keep 
droplets, and to a lesser extent airborne particulates, on the side of 
the filter from which they originate. An explanation of the term ``face 
covering'', as used in this ETS, can be found in the Summary and 
Explanation for paragraph (c) (Section VI.C. of this preamble). The CDC 
(August 13, 2021) recommends unvaccinated people wear face coverings 
when indoors to prevent getting and spreading COVID-19 mostly by 
blocking large respiratory droplets from either leaving the face 
covering of the wearer (source control) or by preventing someone else's 
droplets from reaching the wearer (personal protection). The need for 
face coverings in workplaces applies particularly to unvaccinated 
workers due to their increased potential for asymptomatic and pre-
symptomatic transmission of COVID-19.
    The CDC Healthcare Infection Control Practices Advisory Committee's 
(HICPAC) ``Isolation Guidance'' for healthcare settings has long 
recommended facemasks, among other controls, to prevent the 
transmission of viruses that cause respiratory illnesses (Siegel et 
al., 2007). Face coverings play an important dual role in protecting 
workers from droplet transmission of COVID-19. One of their key 
purposes is to function as source control. In this role, the face 
covering helps protect people around the wearer by reducing the number 
of infectious droplets released into the air by the wearer and limiting 
the distance traveled by any particles that are released. As a result, 
anyone near the wearer is exposed to fewer (if any) droplets and the 
transmission risk is lowered (OSHA,



January 28, 2021; Siegel et al., 2007). Face coverings also provide a 
degree of particulate filtration to reduce the amount of inhaled 
particulate matter, meaning face coverings can help protect the wearer 
themselves, by reducing their inhalation of droplets produced by an 
infected person nearby (CDC, May 7, 2021; Brooks et al., February 10, 
2021).
    The efficacy of any given face covering in either functioning as 
source control or protecting the wearer will depend on the 
construction, design, and material used for the face covering. The CDC 
has stated that ``masks are primarily intended to reduce the emission 
of virus-laden droplets (``source control''), which is especially 
relevant for asymptomatic or presymptomatic infected wearers who feel 
well and may be unaware of their infectiousness to others, and who are 
estimated to account for more than 50% of transmissions'' (CDC, May 7, 
2021). The CDC has also stated that: ``Multi-layer cloth masks block 
release of exhaled respiratory particles into the environment, along 
with the microorganisms these particles carry. Cloth masks not only 
effectively block most large droplets (i.e., 20-30 microns and larger) 
but they can also block the exhalation of fine droplets and particles 
(also often referred to as aerosols) smaller than 10 microns; which 
increase in number with the volume of speech and specific types of 
phonation. Multi-layer cloth masks can both block up to 50-70% of these 
fine droplets and particles and limit the forward spread of those that 
are not captured. Upwards of 80% blockage has been achieved in human 
experiments that have measured blocking of all respiratory droplets, 
with cloth masks in some studies performing on par with surgical masks 
as barriers for source control'' (CDC, May 7, 2021). Thus, the 
construction of the face covering is a significant factor in 
determining its efficacy at reducing COVID-19 transmission.
    While face coverings are generally effective as source control, 
because of the potential variations in protective properties, OSHA has 
not considered face coverings that are not certified to a consensus 
standard to be personal protective equipment (PPE) under OSHA's general 
PPE standard (29 CFR 1910.132), as there is insufficient assurance that 
any given face covering is of safe design and construction for the work 
to be performed, which is required by the PPE standard. Despite these 
limitations, many of the available face coverings have proven to be 
effective at providing source control, and where a face covering is 
also effective in providing personal protection, the wearer will be at 
reduced risk of, and could be protected from, infection. Accordingly, 
over the course of the pandemic, through its guidance, OSHA has 
strongly encouraged workers to wear face coverings when they are in 
close contact with others to reduce the risk of spreading COVID-19 
despite the shortcomings that have prevented the agency from 
considering them to be PPE that complies with the requirement of the 
PPE standard. To enhance the effectiveness of any face covering 
required by this standard, this ETS imposes certain minimum design 
criteria, consistent with CDC recommendations. Thus, the face covering 
must consist of at least two layers of material that is either tightly 
woven or non-woven, and the face covering must not have visible holes 
or openings. CDC has found face coverings that are tightly woven and 
made with at least two layers are more effective at filtering droplets 
than face coverings that are loosely woven or consist of a single layer 
of fabric (CDC, May 7, 2021; Ueki et al., June 25, 2020).
    OSHA's determination on the importance of face coverings is 
supported by a substantial body of evidence. As described in further 
detail below, consistent and correct use of face coverings is widely 
recognized and scientifically supported as an important evidence-based 
strategy for COVID-19 control. Accordingly, with specific exceptions 
relevant to outdoor areas and vaccinated persons, the CDC recommends 
everyone two years of age and older wear a face covering in public 
settings and when around people outside of their household (CDC, August 
13, 2021). And, on January 21, 2021, President Biden issued Executive 
Order 13998, which recognizes the use of face coverings or facemasks as 
a necessary, science-based public health measure to prevent the spread 
of COVID-19, and therefore directed regulatory action to require that 
they be worn in compliance with CDC guidance while traveling on public 
transportation (e.g., buses, trains, subway) and while at airports 
(Executive Order 13998, 86 FR 7205, 7205 (Jan. 21, 2021); CDC, February 
2, 2021). Similarly, the World Health Organization (WHO) has recognized 
face coverings as a key measure in suppressing COVID-19 transmission, 
and thus, saving lives. The WHO observes that face coverings serve two 
purposes, to both protect healthy people from acquiring COVID-19 and to 
prevent sick people from further spreading it. Since December of 2020, 
the WHO has recommended that the general public wear face coverings in 
indoor settings and in outdoor settings where physical distancing 
cannot be maintained (WHO, December 1, 2020).
    In the United States, several states have imposed statewide face 
covering mandates in order to mitigate the spread of COVID-19. One 
study examined data on statewide face covering mandates during March 1-
October 22, 2020, and found that statewide face covering mandates were 
associated with a decline in weekly COVID-19-associated hospitalization 
growth rates by up to 5.6 percentage points for adults aged 18-64 years 
after mandate implementation, compared with growth rates during the 4 
weeks preceding implementation of the mandate (Joo et al., February 12, 
2021). Similarly, another study examined the association of state-
issued face covering mandates with COVID-19 cases and deaths during 
March 1-December 31, 2020, and found mandating face coverings was 
associated with a decrease in daily COVID-19 case and death growth 
rates within 20 days of implementation (Guy et al., March 12, 2021).
    School face covering policies for students, staff members, faculty, 
and visitors are associated with a reduction in COVID-19 outbreaks. 
Between July 15 and August 31, 2021, schools in Arizona were analyzed 
for school mask policies, which provided that all persons, regardless 
of vaccination status, were required to wear a mask indoors. The odds 
of a school-associated COVID-19 outbreak in schools without a mask 
requirement were 3.5 times higher than those in schools with an early 
mask requirement (Odds Ratio = 3.5; 95% Confidence Interval = 1.8-6.9) 
(Jehn et al., October 1, 2021).
    The effectiveness of face coverings in limiting the emission and 
spread of droplets has also been demonstrated in numerous studies. For 
example, multiple studies in which droplets were visualized while 
individuals were talking or a manikin was used to simulate coughs and 
sneezes demonstrated that two-layer face coverings limited the number 
of droplets released into the air, and limited the forward spread of 
those not captured (Fischer et al., September 2, 2020; Verma et al., 
June 30, 2020; CDC, May 7, 2021).
    The effectiveness of face coverings in preventing infections was 
also observed in a number of epidemiological studies. For example, in 
June of 2020 an outbreak was studied aboard the USS Theodore Roosevelt, 
an environment notable for congregate living quarters, close working 
environments, and a sample of mostly young, healthy adults. The 
investigation found that use of face


coverings on board was associated with a 70% reduced risk of 
transmission, which demonstrates that the use of face coverings, 
especially among asymptomatic cases, can help mitigate future 
transmission (Payne et al., June 12, 2020). Another publication, 
released in July of 2020, included an investigation of a high-exposure 
event among 139 clients exposed to two symptomatic hair stylists with 
confirmed cases of COVID-19. Both of the stylists and all of their 
clients wore face coverings during their interactions. Among 67 clients 
subsequently tested for COVID-19, all test results were negative; no 
symptomatic secondary cases were reported by any clients, including 
those who were not tested. The study concluded that the strict use of 
face coverings likely mitigated the spread of COVID-19 (Hendrix et al., 
July 17, 2020).
    Several other observational epidemiological studies have reviewed 
data regarding the ``real-world'' effectiveness of face covering usage. 
First, in a study of 124 Beijing households with one or more 
laboratory-confirmed case of COVID-19, face covering use by both the 
index patient and all family contacts before the index patient 
developed symptoms reduced secondary transmission (i.e., infections 
occurring within two weeks of symptom onset in the index case) within 
the households by 79% (Wang et al., May 11, 2020). Second, a 
retrospective case-control study from Thailand documented that, among 
more than 1,000 persons interviewed as part of contact tracing 
investigations, those who reported having always worn a face covering 
during high-risk exposures experienced a greater than 70% reduced risk 
of infection compared with persons who did not wear face coverings 
under these circumstances. The risk for infection was not significantly 
lower in those who reported only sometimes wearing face coverings 
compared to those who did not wear face coverings at all. This evidence 
supports the conclusion that face coverings must be worn consistently 
and correctly to meaningfully reduce the risk of infection (Doung-ngern 
et al., September 14, 2020).
    Community-level analyses have also confirmed the benefit of 
universal face covering use in: A unified hospital system (Wang et al., 
July 14, 2020); a German city (Mitze et al., June 1, 2020); a U.S. 
state (Gallaway et al., October 6, 2020); a panel of 15 U.S. states and 
Washington, DC (Lyu and Wehby, June 16, 2020; Hatzius et al., June 29, 
2020); as well as both Canada (Karaivanov et al., October 1, 2020) and 
the U.S. (Chernozhukov et al., September 15, 2020) nationally. Each 
community analysis demonstrated that, following universal face covering 
directives from both organizational and political leadership, new 
infections were shown to fall significantly. These analyses have also 
shown reductions in mortality and the need for lockdowns, with their 
associated monetary/gross domestic product losses (Leffler et al., 
December 2, 2020; Hatzius et al., June 29, 2020). Additionally, 
multiple investigations involving infected passengers aboard flights 
longer than ten hours strongly suggest that face covering usage 
prevented in-flight transmissions, as demonstrated by the absence of 
infection developing in other passengers and crew in the 14 days 
following exposure (Schwartz et al., April 14, 2020; Freedman and 
Wilder-Smith, September 25, 2020).
    Researchers from the COVID-19 Systematic Urgent Review Group Effort 
investigated the effects of face coverings and eye protection on virus 
transmission in both healthcare and non-healthcare settings. They 
identified 172 observational studies for their systematic review and 44 
comparative studies for their meta-analysis, including data on 25,697 
COVID-19, SARS, or MERS patients. They concluded for the general 
public, based mainly on evidence from face covering use within 
households and among contacts of cases, that disposable surgical masks 
or face coverings (reusable multi-layer cotton face coverings) are 
associated with protection from viral transmission. Through the meta-
analysis, combining 39 of the studies' results, they found a 14.3% 
reduction in the difference of anticipated absolute effect (e.g., the 
chance of viral infection or transmission) between no face covering and 
face covering groups (Chu et al., June 27, 2020).
    Ueki et al. (June 25, 2020) evaluated the effectiveness of cotton 
face coverings, facemasks, and N95s (a commonly used respirator) in 
preventing transmission of SARS-CoV-2 using a laboratory experimental 
setting with manikins. The researchers found that all offerings 
provided some measure of protection as source control, limiting 
droplets expelled from both infected and uninfected wearers. For 
instance, when spaced roughly 20 inches apart, an uninfected person can 
reduce inhalation of infectious virus by 37% by wearing a cotton face 
covering. If only the infected person wears a cotton face covering, the 
amount breathed in by the uninfected recipient is reduced by 57%. 
However, if both individuals wear a cotton face covering, the exposure 
is reduced 67%. If both are wearing facemasks, exposure is reduced by 
76%. When an infected individual wore an N95 respirator, exposure was 
reduced by 96% or, w
