SUPPLEMENTARY INFORMATION:

I. Background

    Section 101(c) of the Federal Mine Safety and Health Act of 1977 (Mine Act) allows the mine operator or representative of miners to file a petition to modify the application of any mandatory safety standard to a coal or other mine if the Secretary of Labor determines that:
    (1) An alternative method of achieving the result of such standard exists which will at all times guarantee no less than the same measure of protection afforded the miners of such mine by such standard; or
    (2) That the application of such standard to such mine will result in a diminution of safety to the miners in such mine.
    In addition, the regulations at 30 CFR 44.10 and 44.11 establish the requirements and procedures for filing petitions for modification.

II. Petitions for Modification

Docket No: M-2013-005-C.
Petitioner: Peabody Midwest Mining, LLC, Three Gateway Center, Suite 1500, 401 Liberty Avenue, Pittsburgh, Pennsylvania 15222-1000.
Mine: Francisco Mine Underground Pit, MSHA I.D. No. 12-02295, located in Gibson County, Indiana.
Regulation Affected: 30 CFR 75.500(d) (Permissible electric equipment).
Modification Request: The petitioner requests a modification of the existing standard to permit an alternative method of compliance to allow the use of battery-powered nonpermissible surveying equipment in or inby the last open crosscut, including, but not limited to, portable battery-operated mine transits, total station surveying equipment, distance meters, and data loggers. The petitioner states that:
    (1) To comply with requirements for mine ventilation maps and mine maps in 30 CFR 75.372 and 75.1200, use of the most practical and accurate surveying equipment is necessary.
    (2) Application of the existing standard would result in a diminution of safety to the miners. Underground mining by its nature and size, and the complexity of mine plans, requires that accurate and precise measurements be completed in a prompt and efficient manner. The petitioner proposes the following as an alternative to the existing standard:
    (a) Nonpermissible electronic surveying equipment may be used. Such nonpermissible surveying equipment includes portable battery-operated total station surveying equipment, mine transits, distance meters, and data loggers.
    (b) All nonpermissible electronic surveying equipment to be used in or inby the last open crosscut will be examined by surveying personnel prior to use to ensure the equipment is being maintained in a safe operating condition. These examinations will include the following steps:
    (i) Checking the instrument for any physical damage and the integrity of the case.
    (ii) Removing the battery and inspecting for corrosion.
    (iii) Inspecting the contact points to ensure a secure connection to the battery.
    (iv) Reinserting the battery and powering up and shutting down to ensure proper connections.
    (v) Checking the battery compartment cover to ensure that it is securely fastened.
    (c) The results of such examinations will be recorded and retained for one year and made available to MSHA on request.
    (d) A qualified person as defined in 30 CFR 75.151 will continuously monitor for methane immediately before and during the use of nonpermissible surveying equipment in or inby the last open crosscut.
    (e) Nonpermissible surveying equipment will not be used if methane is detected in concentrations at or above one percent for the area being surveyed. When methane is detected at such levels while the nonpermissible surveying equipment is being used, the equipment will be deenergized immediately and the nonpermissible electronic equipment withdrawn outby the last open crosscut.
    (f) All hand-held methane detectors will be MSHA-approved and maintained in permissible and proper operating condition as defined in 30 CFR 75.320.
    (g) Batteries in the surveying equipment will be changed out or charged in fresh air outby the last open crosscut.
    (h) Qualified personnel who use surveying equipment will be properly trained to recognize the hazards associated with the use of nonpermissible surveying equipment in areas where methane could be present.
    (i) The nonpermissible surveying equipment will not be put into service until MSHA has initially inspected the equipment and determined that it is in compliance with all the terms and conditions in this petition.
    The petitioner asserts that the proposed alternative method will at all times guarantee no less than the same measure of protection as that afforded by the existing standard.

    (1) To comply with requirements for mine ventilation maps and mine maps in 30 CFR 75.372 and 75.1200, use of the most practical and accurate surveying equipment is necessary. To ensure the safety of the miners in active mines and to protect miners in future mines that may mine in close proximity to these same active mines, it is necessary to determine the exact location and extent of the mine workings.
    (2) Application of the existing standard would result in a diminution of safety to the miners. Underground mining, by its nature and size and the complexity of mine plans, requires that accurate and precise measurements be completed in a prompt and efficient manner. The petitioner proposes the following as an alternative to the existing standard:
    (a) Nonpermissible electronic surveying equipment may be used. Such nonpermissible surveying equipment includes portable battery-operated total station surveying equipment, mine transits, distance meters, and data loggers.
    (b) All nonpermissible electronic surveying equipment to be used within 150 feet of pillar workings will be examined by surveying personnel prior to use to ensure the equipment is being maintained in a safe operating condition. These examinations will include the following steps:
    (i) Checking the instrument for any physical damage and the integrity of the case.
    (ii) Removing the battery and inspecting for corrosion.
    (iii) Inspecting the contact points to ensure a secure connection to the battery.
    (iv) Reinserting the battery and powering up and shutting down to ensure proper connections.
    (v) Checking the battery compartment cover to ensure that it is securely fastened.
    (c) The results of such examinations will be recorded and retained for one year and made available to MSHA on request.
    (d) A qualified person as defined in 30 CFR 75.151 will continuously monitor for methane immediately before and during the use of nonpermissible surveying equipment within 150 feet of pillar workings.
    (e) Nonpermissible surveying equipment will not be used if methane is detected in concentrations at or above one percent for the area being surveyed. When methane is detected at such levels while the nonpermissible surveying equipment is being used, the equipment will be deenergized immediately and the nonpermissible electronic equipment withdrawn further than 150 feet from pillar workings.
    (f) All hand-held methane detectors will be MSHA-approved and maintained in permissible and proper operating condition as defined in 30 CFR 75.320.
    (g) Batteries in the surveying equipment will be changed out or charged in fresh air more than 150 feet from pillar workings.
    (h) Qualified personnel who use surveying equipment will be properly trained to recognize the hazards associated with the use of nonpermissible surveying equipment in areas where methane could be present.
    (i) The nonpermissible surveying equipment will not be put into service until MSHA has initially inspected the equipment and determined that it is in compliance with all the terms and conditions in this petition.
    The petitioner asserts that the proposed alternative method will at all times guarantee no less than the same measure of protection as that afforded by the existing standard.
