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 (Secretary) 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, as designee of the Secretary, has granted or partially granted the requests for modification listed below. In some instances, the decisions are conditioned upon compliance with stipulations stated in the decision. The term AFR Notice appears in the list of affirmative decisions below. The term refers to the Federal Register volume and page where MSHA published a notice of the filing of the petition for modification.
FOR FURTHER INFORMATION CONTACT:
Petitions and copies of the final decisions are available for examination by the public in the Office of Standards, Regulations, and Variances, MSHA, 1100 Wilson Boulevard, Room 2352, Arlington, Virginia 22209. Contact Barbara Barron at 202-693-9447.
