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 Number: M-2013-035-C.
    Petitioner: Five Star Mining, Inc., 6594 West State Road 56, 
Petersburg, Indiana 47567.
    Mine: Prosperity Mine, MSHA I.D. No. 12-02249, located in Pike 
County, Indiana.
    Regulation Affected: 30 CFR 75.503 (Permissible electric face 
equipment; maintenance), 30 CFR 18.35(a)(5)(i)(ii) (Portable (trailing) 
cables and cords).
    Modification Request: The petitioner requests a modification of the 
existing standard to permit the maximum length of trailing cables to be 
increased for supplying power to permissible pumps in the Prosperity 
Mine. The petitioner states that:
    (1) This petition will apply only to trailing cables supplying 
three-phase, 480-volt, 3-phase power for permissible pumps.
    (2) The maximum length of the trailing cables supplying 480-volts 
to permissible pumps will be 4,000 feet.
    (3) Trailing cables or cords over 500 feet supplying power to 480-
volt permissible pumps will not be smaller than No. 6 American Wire 
Gauge (AWG).
    (4) All circuit breakers used to protect the No. 6 AWG trailing 
cables exceeding 550 feet in length will have an instantaneous trip 
unit calibrated to trip at 60 amperes. The trip setting of these 
circuit breakers will be sealed or locked so that the setting cannot be 
changed, and will have permanent, legible labels. Each label will 
identify the circuit breaker as being suitable for protecting No. 6 AWG 
cables. This label will be maintained legible.
    (5) Replacement instantaneous trip units used to protect No. 6 AWG 
trailing cables will be calibrated to trip at 60 amperes and this 
setting will be sealed or locked.
    (6) All circuit breakers used to protect the No. 2 AWG trailing 
cables exceeding 700 feet in length will have an instantaneous trip 
unit calibrated to trip at 150 amperes. The trip setting of these 
circuit breakers will be sealed or locked so that the setting cannot be 
changed, and these circuit breakers will have permanent, legible 
labels. Each label will identify the circuit breaker as being suitable 
for protecting No. 2 AWG trailing cables. This label will be maintained 
legible.
    (7) Replacement instantaneous trip units used to protect No. 2 AWG 
trailing cables will be calibrated to trip at 150 amperes and this 
setting will be sealed or locked.
    (8) All components that provide short-circuit protection will have 
a sufficient interruption rating in accordance with the maximum 
calculated fault currents available.
    (9) The short-circuit setting will not exceed the setting specified 
in the approval documentation or 70 percent of the minimum available 
current, whichever is less.
    (10) Permanent warning labels will be installed and maintained on 
the cover(s) of the power center or distribution box to identify the 
location of each sealed short-circuit protection device. These labels 
will warn miners not to change or alter the sealed short-circuit 
settings.
    (11) Within 60 days after this proposed decision and order becomes 
final, the proposed revisions for the petitioner's approved 30 CFR part 
48 training plan will be submitted to the District Manager. The 
training plan will include the following:
    (a) Mining methods and operating procedures for protecting the 
trailing cables against damage.
    (b) Proper procedures for examining the trailing cables to ensure 
safe operating condition.
    (c) The hazards of setting the short-circuit interrupting device(s) 
too high to adequately protect the trailing cables.
    (d) How to verify that the circuit interrupting device(s) 
protecting the trailing cable(s) are properly set and maintained.
    The petitioner further states that procedures specified in 30 CFR 
48.3 for proposed revisions to approved training plans will apply.
    The petitioner asserts that the alternative method will guarantee 
no less than the same measure of protection for all miners than that of 
the existing standard.

    Docket Number: M-2013-036-C.
    Petitioner: Pinnacle Mining Company, LLC, P.O. Box 338, Pineville, 
West Virginia 24874,

    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 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 and limitations 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.

    Docket Number: M-2013-037-C.
    Petitioner: Pinnacle Mining Company, LLC, P.O. Box 338, Pineville, 
West Virginia 24874,

permissibility requirements).
    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 
return airways, 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 
return airways will be examined 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

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.
    Docket Number: M-2013-038-C.
    Petitioner: Pinnacle Mining Company, LLC, P.O. Box 338, Pineville, 
West Virginia 24874.
    Mine: Pinnacle Mine, MSHA I.D. No. 46-01816, located in Wyoming 
County, West Virginia.
    Regulation Affected: 30 CFR 75.1002(a) (Installation of electric 
equipment and conductors; permissibility).
    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 
within 150 feet of pillar workings, 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, 75.1002(a), 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 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 and limitations 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.
