    SUMMARY: The Mine Safety and Health Administration (MSHA) is announcing 
    the extension of the public comment periods on its proposed rules 
    addressing diesel particulate matter exposure of underground coal 
    miners as published in the Federal Register on April 9, 1998, and for 
    underground metal and nonmetal miners published on October 29, 1998.
        This document also announces the availability of three additional 
    studies applicable to both rulemakings addressing diesel particulate 
    matter exposure of underground coal and underground metal and nonmetal 
    miners. These studies supplement the evidence in both rulemaking 
    records regarding the risks to underground miners of serious health 
    hazards
    
    [[Page 7145]]
    
    associated with exposure to high concentrations of diesel particulate 
    matter. The Agency, therefore, intends to include these studies in both 
    rulemaking records and make them available to interested parties upon 
    request. These studies do not change the Agency's proposed findings.
        The Agency is also announcing that it will hold public hearings on 
    its proposed rule addressing diesel particulate matter exposure in 
    underground metal and nonmetal mines in the following locations: Salt 
    Lake City, Utah; Albuquerque, New Mexico; St. Louis, Missouri; and 
    Knoxville, Tennessee.
    
    DATES: Written comments on the three studies and on both proposed rules 
    must be submitted on or before April 30, 1999.
        The hearing dates, times and specific locations will be announced 
    by a separate notice in the Federal Register. The rulemaking record for 
    the metal and nonmetal proposed rule will remain open 60 days after the 
    last public hearing.
    
    ADDRESSES: Copies of the three studies are available to interested 
    members of the public and may be obtained from the Office of Standards, 
    Regulations and Variances, 703-235-1910.
        Comments on the proposed rules may be transmitted by electronic 
    mail, fax, or mail. Comments by electronic mail must be clearly 
    identified as such and sent to this E-mail address: comments@msha.gov. 
    Comments by fax must be clearly identified as such and sent to: MSHA, 
    Office of Standards, Regulations, and Variances, 703-235-5551. Send 
    mail comments to: MSHA, Office of Standards, Regulations, and 
    Variances, Room 631, 4015 Wilson Boulevard, Arlington, VA 22203-1984. 
    Interested persons are encouraged to supplement written comments with 
    computer files or disks; please contact the Agency with any questions 
    about format.

    SUPPLEMENTARY INFORMATION: On April 9, 1998 (63 FR 17492) and October 
    29, 1998 (63 FR 58104), MSHA published proposed rules to reduce the 
    risks to underground coal and metal and nonmetal miners, respectively, 
    of serious health hazards that are associated with exposure to high 
    concentrations of diesel particulate matter (dpm). DPM is a very small 
    particle in diesel exhaust. Underground miners are exposed to far 
    higher concentrations of this fine particulate than any other group of 
    workers.
    
    A. Cumulative Evidence
    
        In its proposals, MSHA stated that the best available evidence 
    indicates that such high exposures put these miners at excess risk of a 
    variety of adverse health effects, including lung cancer. There is 
    clear evidence that exposure to high concentrations of dpm can result 
    in a variety of serious health effects. These health effects include: 
    (1) Sensory irritations and respiratory symptoms serious enough to 
    distract or disable miners; (2) death from cardiovascular, 
    cardiopulmonary, or respiratory causes; and (3) lung cancer.
        The Agency has reviewed cumulative evidence to support its findings 
    that underground miners are at risk from exposure to dpm. MSHA intends 
    to supplement the rulemaking records with the following studies:

    Coal Industry, 1973-1992,'' Medical Journal of Australia, 163(1):19-
    21, July 3, 1995.
        (2) Johnston, A.M., et al., ``Investigation of the Possible 
    Association Between Exposure to Diesel Exhaust Particulates in 
    British Coal Mines and Lung Cancer,'' Institute of Occupational 
    Medicine (IOM), Report TM/97/08, (Edinburgh, Scotland), November 
    1997.

    the Trucking Industry: Exposure-Response Analyses and Risk

        These studies are available and may be obtained by contacting the 
    Office of Standards, Regulations and Variances, 703-235-1910.
    
    B. Diesel Particulate Matter Exposure of Underground Coal Miners
    
        The post-hearing comment period for the proposed rule addressing 
    diesel particulate matter exposure of underground coal miners was 
    scheduled to close on February 16, 1999 (63 FR 55811). However, in 
    response to requests from the public to extend the post-hearing comment 
    period, and in order to give the public an opportunity to comment on 
    the three studies, the record for the coal proposed rule will remain 
    open until April 30, 1999. This provides a total of 12 months from date 
    of publication for the public to comment on the proposed rule.
    
    C. Diesel Particulate Matter Exposure of Underground Metal and 
    Nonmetal Miners
    
        The comment period for the proposed rule addressing diesel 
    particulate matter exposure of underground metal and nonmetal miners 
    was scheduled to close on February 26, 1999 (63 FR 58104). The Agency 
    has received several requests from the public for additional time to 
    prepare their comments on the proposed rule. Since the Agency also 
    intends to supplement the rulemaking record with three new studies, the 
    public comment period will be extended until April 30, 1999.
        MSHA believes that extension of the comment periods for both 
    rulemakings will provide sufficient time for all interested parties to 
    review the studies and the proposed rules, and submit comments. All 
    interested members of the mining community are encouraged to submit 
    comments prior to April 30, 1999.
    
    D. Public Hearings
    
        MSHA plans to hold public hearings on the proposed rule addressing 
    diesel particulate matter exposure of underground metal and nonmetal 
    miners. The hearings will be held in Salt Lake City, Utah; Albuquerque, 
    New Mexico; St. Louis, Missouri; and Knoxville, Tennessee. The hearing 
    dates, times, and specific locations will be announced by a separate 
    document in the Federal Register. The hearings will be held under 
    Section 101 of the Federal Mine Safety and Health Act of 1977.
