[Docket No. H-71]

RIN 1218-AA98

Occupational Exposure to Methylene Chloride

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

ACTION: Proposed rule; corrections.

SUMMARY: This notice corrects errors that appeared in the Notice of Proposed Rulemaking (NPRM) for Occupational Exposure to Methylene Chloride that the Occupational Safety and Health Administration (OSHA) published on November 7, 1991 (56 FR 57036).

DATES: Comments and requests for a hearing concerning the proposed standard must be postmarked on or before April 6, 1992.

ADDRESSES: Comments are to be submitted in quadruplicate to: The Docket Office, Docket No. H-71, United States Department of Labor, Room N-2634, 200 Constitution Avenue, N.W., Washington, D.C. 20210, telephone (202) 523-7894.

Comments limited to 10 pages or less in length also may be transmitted by facsimile to (202) 523-5046 or 8-523-5046 (for FTS), provided that the original and 3 copies are sent to the Docket Office thereafter.

Requests for a hearing are to be submitted in quadruplicate to Mr. Tom Hall, OSHA, U.S. Department of Labor, Room N-3647, 200 Constitution Avenue, N.W. Washington, D.C. 20210, telephone (202) 523-8615.

FOR FURTHER INFORMATION CONTACT: Mr. James F. Foster, OSHA Office of Public Affairs, United States Department of Labor, Room N-3641, 200 Constitution Avenue, N.W., Washington, D.C. 20210, telephone (202) 523-8151.

SUPPLEMENTARY INFORMATION: On November 7, 1991, the Occupational Safety and Health Administration issued a notice of proposed rulemaking (NPRM) for occupational exposure to methylene chloride (56 FR 57036). Two errors were introduced into the preamble of the NPRM during the process of editing the document for publication. In the first instance, OSHA inadvertently failed to revise Table 18 and Table 19 in the Summary of Preliminary Regulatory Impact and Regulatory Flexibility Analysis so that they reflected the corresponding text (56 FR 57108) regarding the benefits of a revised standard. Those tables are corrected to read as follows:

In the second instance, the Public Participation section of the NPRM (56 FR 57128) did not provide the requisite notice that interested persons have the right to file objections to the proposal and request an informal hearing. The Public Participation section is corrected to read as follows:

XIII. Public Participation

Interested persons are invited to submit written data, views, and arguments with respect to this proposed standard. These comments must be postmarked on or before April 6, 1992, and submitted to quadruplicate to the Docket Officer, Docket No. H-71, Room N-2625, U.S. Department of Labor, 200 Constitution Avenue, N.W., Washington, D.C. 20210. Comments limited to 10 pages or less also maybe transmitted by facsimile to 202-523-5046 or FTS 8-523-5046, provided the original and three copies are sent to the Docket Office thereafter. Written submissions must clearly identify the provisions of the proposal which are addressed and the position taken with respect to each issue.

The data, views, and arguments that are submitted will be available for public inspection and copying at the above address. All timely written submissions will be made a part of the record of the proceeding.

Additionally, under section 6(b)(3) of the OSH Act (29 U.S.C. 655), section 107 of the Construction Safety Act (41 U.S.C. 333), and 29 CFR 1911.11, interested persons may file objections to the proposal and request an informal hearing. The objections and hearing requests should be submitted in quadruplicate to the Docket Officer at the address above and must comply with the following conditions:

1. The objections must include the name and address of the objector;

2. The objections must be postmarked by April 6, 1992.

3. The objections must specify with particularity the provisions of the proposed rule to which each objection is taken and must state the grounds therefor;

4. Each objection must be separately stated and numbered; and

5. The objections must be accompanied by a detailed summary of the evidence proposed to be adduced at the requested hearing.

This document was prepared under the direction of Gerard F. Scannell, Assistant Secretary of Labor for Occupational Safety and Health, U.S. Department of Labor, 200 Constitution Avenue, NW., Washington, DC 20210.

It is issued pursuant to section 6(b) of the Occupational Safety and Health Act of 1970 (29 U.S.C. 655); Secretary of Labor's Order 1-90 (55 FR 9033); and 29 CFR part 1911.

Signed at Washington DC, this 18th day of December, 1991.
