Summary of Decisions Granting in Whole or in Part Petitions for Modification

AGENCY: Mine Safety and Health Administration (MSHA), Labor.

ACTION: Notice of affirmative decisions issued by the Administrators for Coal Mine Safety and Health and Metal and Nonmetal Mine Safety and Health on petitions for modification of the application of mandatory safety standards.

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

SUMMARY: Under section 101 of the Federal Mine Safety and Health Act of 1977, the Secretary of Labor may allow the modification of the application of a mandatory safety standard to a mine if the Secretary determines either that an alternate method exists at a specific mine that will guarantee no less protection for the miners affected than that provided by the standard, or that the application of the standard at a specific mine will result in a diminution of safety to the affected miners.

Final decisions on these petitions are based upon the petitioner's statements, comments and information submitted by interested persons, and a field investigation of the conditions at the mine. MSHA has granted or partially granted the requests for modification submitted by the petitioners listed below. In some instances, the decisions are conditioned upon compliance with stipulations stated in the decision. The cite following "FR Notice:'' refers to the issue of the Federal Register where MSHA published the notice that the petitioner was seeking a modification.

FOR FURTHER INFORMATION: Petitions and copies of the final decisions are available for examination by the public in the Office of Standards, Regulations, and Variances, MSHA, Room 627, 4015 Wilson Boulevard, Arlington, Virginia 22203. Contact Barbara Barron at 703-235-1910.
