    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(c) of the Federal Mine Safety and Health Act 
    of 1977, the Secretary of Labor may modify 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.
        Summaries of petitions received by the Secretary appear 
    periodically in the Federal Register. 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.
    
    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.
