Availability of completed regulatory review.
The Occupational Safety and Health Administration (OSHA) has completed a review of the Methylene Chloride (MC) Standard (29 CFR 1910.1052) pursuant to section 610 of the Regulatory Flexibility Act and section 5 of Executive Order 12866 on Regulatory Planning and Review. The purpose of this review was to determine whether the MC Standard has functioned as intended, whether it could be simplified or improved to reduce the regulatory burden on small businesses, or whether it is no longer needed and should be rescinded.
As of May 5, 2010 the report is available to the public, (see ADDRESSES section to obtain copies).
Copies of the entire report may be obtained from the OSHA Publications Office, Room N-3101, 200 Constitution Avenue, NW., Washington, DC 20210; telephone (202) 693-1888; fax (202) 693-2498. All documents and comments received relevant to the review and documents discussed in this report are available at the OSHA Docket Office, Docket No. OSHA-2007-0024, Technical Data Center, Room N-2625, U.S. Department of Labor, 200 Constitution Avenue, NW., Washington, DC 20210, Telephone (202) 693-2350.

MC (also known as methylene dichloride or dichloromethane [DCM or MC]) is a common industrial solvent used in a number of different applications, including paint stripping, metal cleaning and the manufacture of plastics and adhesives. Without proper ventilation or respiratory protection, short-term exposure to large amounts of MC can cause respiratory or central nervous system failure. In 1985, the U.S. Environmental Protection Agency (EPA) determined that MC was a probable human carcinogen and posed a long term danger to human health. EPA promulgated rules governing the use of MC in several industries during 1994-1995. On January 10, 1997, OSHA published its final MC Standard to protect workers from occupational exposure to MC. It reduced the permissible exposure limit from an 8-hour-time-weighted-average (TWA) of 500 parts per million (ppm) to 25 ppm.
The purpose of this lookback study was to review the current MC Standard, in accordance with section 610 of the Regulatory Flexibility Act and Section 5 of Executive Order 12866, to determine whether the rule has functioned as intended, whether it could be simplified or improved, or whether it is no longer needed and should be rescinded. The purpose of a review under section 610 of the Regulatory Flexibility Act is:
“to determine whether such rule should be continued without change, or should be rescinded, or amended consistent with the stated objectives of applicable statutes to minimize any significant impact of the rules on a substantial number of small entities.”
In conducting a section 610 review, the Agency must consider the following factors:
“(1) The continued need for the rule;
(2) The nature of complaints or comments received concerning the rule from the public;
(3) The complexity of the rule;
(4) The extent to which the rule overlaps, duplicates or conflicts with other Federal rules, and, to the extent feasible, with State and local governmental rules; and
(5) The length of time since the rule has been evaluated or the degree to which technology, economic conditions, or other factors have changed in the area affected by the rule.”
The review requirements of section 5 of EO 12866 require agencies:
“To reduce the regulatory burden on the American people, their families, their communities, their State, local, and tribal governments, and their industries; to determine whether regulations promulgated by the [Agency] have become unjustified or unnecessary as a result of changed circumstances; to confirm that regulations are both compatible with each other and not duplicative or inappropriately burdensome in the aggregate; to ensure that all regulations are consistent with the President's priorities and the principles set forth in this Executive Order, within applicable law; and to otherwise improve the effectiveness of existing regulations.”
To carry out its lookback review of the MC Standard under these provisions, OSHA requested public comment, on July 10, 2007, on: the impacts of the rule Start Printed Page 24510on small businesses; the benefits and utility of the rule in its current form and, if amended, in its amended form; the continued need for the rule; the complexity of the rule; and whether, and to what extent, the rule overlaps, duplicates, or conflicts with other Federal, State, and local government rules. OSHA also asked for comments on new developments in technology, economic conditions, or other factors affecting the ability of covered firms to comply with the standard. Furthermore, OSHA asked for comments on alternatives to the rule that would minimize significant impacts on small businesses while achieving the objectives of the Occupational Safety and Health Act.
Conclusions and Recommendations
OSHA's Section 610 review of the MC Standard finds the following:
- There is a continued need for the Standard.
- The Standard does not impose an unnecessary or disproportionate burden on small businesses or on industry in general.
- Although the Standard does impose costs, these costs are essential to protecting worker health.
- This lookback review did not identify any industries in which the Standard diminished the industries' viability.
- There is no indication that employers are unable to comply due to the complexity of the Standard.
- The Standard does not overlap, duplicate, or conflict with other state or federal rules.
- Economic and technological trends have not reduced the need for the Standard.
- No public commenter felt the MC Standard should be rescinded. Several of the comments underscored the hazards associated with exposure to MC and that it is feasible to comply with the Standard. Other comments contained specific suggestions for how compliance with the Standard could be improved through compliance assistance, and how worker health could be improved through information on the toxicity of substitutes for MC use.
OSHA's review of the MC Standard under EO 12866 finds the following:
- The Standard remains justified and necessary in light of ongoing hazards and fatalities.
- In general, the Standard is compatible and not duplicative with other state or federal rules.
- The Standard remains consistent with E.O. 12866 because it has produced the intended benefits (i.e., protecting workers' health), and has not been unduly burdensome.
OSHA concludes that the MC Standard has protected workers from adverse health effects resulting from exposure to MC in the workplace. In terms of economic impacts, the MC Standard does not impose an unnecessary or disproportionate burden on small businesses or on industry in general. Although the Standard does impose costs, these costs are essential to protecting worker health. This lookback review did not identify any industries in which the MC Standard diminished the industries' viability.
OSHA recommends the following:
- The MC Standard should continue without change.
- According to public comments, lack of information and training are the most common barriers in the construction industry for compliance with the MC Standard. Therefore, OSHA recommends reviewing its compliance assistance materials to determine the need for updates. OSHA also recommends reviewing the adequacy of how these materials are disseminated and additional means for reaching affected populations.
- The use of substitutes for MC has increased in certain industries. These substitutes may pose their own health hazards. Therefore, based on public comments, OSHA will consider putting out guidance recommending that, before a substitute for MC is used, the toxicity of that substitute should be checked on the EPA and NIOSH Web sites (http://www.epa.gov and http://www.niosh.gov, respectively).
