Michigan State Plan


  • Initial Approval: October 3, 1973 (38 FR 27391)
  • State Plan Certification: January 16, 1981 (46 FR 3862, 3863)
  • Operational Status Agreement: June 9, 2000 (65 FR 36626), amended on October 12, 2011 (76 FR 63191) and January 23, 2017 (82 FR 7867)

The Michigan Occupational Safety and Health Administration (MIOSHA) is part of the Michigan Department of Licensing and Regulatory Affairs. The main office is located in Lansing.


The Michigan State Plan applies to private-sector workplaces in the state with the exception of:

  1. Maritime employment (including shipyard employment, marine terminals, and longshoring, but not including marine construction, which is covered MIOSHA);
  2. Contract workers and contractor-operated facilities engaged in United States Postal Service (USPS) mail operations;
  3. Employers who are enrolled members of Indian tribes and who own or operate businesses located within the boundaries of Indian reservations (non-Indian employers within the reservations and Indian employers outside the territorial boundaries of Indian reservations are covered by MIOSHA); and
  4. All working conditions of aircraft cabin crewmembers onboard aircraft in operation.

The Michigan State Plan also applies to state and local government employers. It does not apply to federal government employers including the United States Postal Service. Federal OSHA covers the issues not covered by the Michigan State Plan. In addition, Federal OSHA retains enforcement of the anti-retaliation provision of the Occupational Safety and Health Act of 1970, Section 11(c), 29 USC 660(c), with respect to the private sector. MIOSHA also investigates private and state and local government workplace retaliation cases under a provision analogous to Section 11(c).

A brief summary of the Michigan State Plan is included in the Code of Federal Regulations (CFR) at 29 CFR 1952.13. Federal OSHA retains the authority to promulgate, modify, or revoke occupational safety and health standards under Section 6 of the OSH Act. In the event that Federal OSHA resumes enforcement, those federal standards will be enforced. Federal OSHA also retains the authority to monitor the State Plan under Section 18(f) of the OSH Act.

Enforcement Programs

The General Industry Safety and Health Division conducts safety and health inspections in general industry within the state. MIOSHA's Construction Safety and Health Division conducts safety and health inspections at construction sites. The MIOSHA Field Operations Manual (FOM) provides guidance for its enforcement program. Compliance officers inspect workplaces for hazardous conditions and issue citations where violations of MIOSHA standards are identified. Inspections may be the result of regular scheduling, imminent danger reports, fatalities, worker complaints, or referrals. For more information, please visit the Michigan State Plan website.

Voluntary and Cooperative Programs

MIOSHA offers voluntary and cooperative programs that focus on reducing injuries, illnesses, and fatalities. MIOSHA also offers on-site consultation services which help employers comply with MIOSHA standards and identify and correct potential safety and health hazards. For more information on these programs, please visit the Michigan State Plan website.

Informal Conferences and Appeals

MIOSHA personnel conduct informal conferences in an effort to resolve contested cases. Cases not resolved by informal conferences are placed in contest and referred to the MIOSHA Appeals Division which hears and rules on appeals from citations. For more information, please visit the Michigan State Plan website.
