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 Numbers: M-2015-003-C.
    Petitioner: Rosebud Mining Company, P.O. Box 1025, Northern 
Cambria, Pennsylvania 15714.
    Mines: Coral-Graceton Mine, MSHA I.D. No. 36-09595 and Crooked 
Creek Mine, MSHA I.D. No. 36-09972, both located in Indiana County, 
Pennsylvania.
    Regulation Affected: 30 CFR 75.503 (Permissible electric face 
equipment; maintenance) and 18.35(a)(5)(i) (Portable (trailing) cables 
and cords).

[[Page 17503]]

    Modification Request: The petitioner requests a modification of the 
existing standard to permit the use of 480-volt trailing cables with a 
maximum length of 1200 feet when No. 2 American Wire Gauge (AWG) cable 
is used and a maximum length of 950 feet when No. 4 AWG cable is used 
on roof bolters. The petitioner states that:
    (1) The trailing cables for the 480-volt bolters will not be 
smaller than No. 4 AWG cable.
    (2) All circuit breakers used to protect the No. 2 AWG trailing 
cable or the No. 4 AWG trailing cable exceeding 700 feet in length will 
have instantaneous trip units calibrated to trip at 500 amperes. The 
trip setting of these circuit breakers will be sealed to ensure that 
the settings cannot be changed, and these circuit breakers will have 
permanent, legible labels. Each label will identify the circuit breaker 
as being suitable for protecting the cables.
    (3) Replacement circuit breakers and/or instantaneous trip units 
used to protect the No. 2 AWG trailing cable or the No. 4 AWG trailing 
cable will be calibrated to trip at 500 amperes and they will be 
sealed.
    (4) All components that provide short-circuit protection will have 
a sufficient interruption rating in accordance with the maximum 
calculated fault currents available.
    (5) During each production day, the trailing cables and the circuit 
breakers will be examined in accordance with all 30 CFR provisions.
    (6) Permanent warning labels will be installed and maintained on 
the load center identifying the location of each short-circuit 
protection device. These labels will warn miners not to change or alter 
the settings of these devices.
    (7) If the affected trailing cables are damaged in any way during 
the shift, the cable will be de-energized and repairs made.
    (8) The alternative method will not be implemented until all miners 
who have been designated to operate the bolters, or any other person 
designated to examine the trailing cables or trip settings on the 
circuit breakers, have received the proper training as to the 
performance of their duties.
    (9) Within 60 days after the proposed decision and order becomes 
final, the petitioner will submit proposed revisions for their approved 
30 CFR part 48 training plans to the District Manager. These revisions 
will specify task training for miners designated to examine the 
trailing cables for safe operating condition and verify that the short-
circuit settings of the circuit-interrupting devices that protect the 
affected trailing cables do not exceed the settings specified 
previously in this petition. The training will include the following 
elements:
    (a) The hazards of setting the short-circuit interrupting device(s) 
too high to adequately protect the trailing cables.
    (b) How to verify that the circuit interrupting device(s) 
protecting the trailing cable(s) are properly set and maintained.
    (c) Mining methods and operating procedures that will protect the 
trailing cables against damage.
    (d) Proper procedures for examining the trailing cables to ensure 
that the cables are in safe operating condition by visually inspecting 
the entire cable, observing the insulation, the integrity of splices, 
nicks and abrasions.
    The petitioner asserts that the proposed alternative method will at 
all times guarantee no less than the same measure of protection 
afforded by the standard.
    Docket Numbers: M-2015-004-C.
    Petitioner: Bowie Resources, LLC, P.O. Box 1488, Paonia, Colorado 
81428.
    Mine: Bowie No. 2 Mine, MSHA I.D. No. 05-04591, located in Delta 
County, Colorado.
    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 infrared scanning and 
digital camera equipment in or inby the last open crosscut. The 
petitioner asserts that equivalent permissible equipment does not 
exist. The petitioner states that:
    (1) Prohibiting the use of an infrared (IR) digital camera under 
the existing standard will result in the reduction of safety for the 
miners at the Bowie No. 2 Mine. The use of the IR will provide an 
effective method to detect and identify small areas of higher than 
normal coal pillar oxidation that may lead to spontaneous combustion.
    (2) Using currently available means of detecting coal pillar 
oxidation, which is limited to hand-held carbon monoxide detectors, 
odor, or smoke is ineffective and may allow oxidation to become a 
heating or spontaneous combustion event.
    (3) In the alternative to compliance with the existing standard the 
petitioner proposes the following:
    (a) Nonpermissible infrared IR scanning and digital equipment will 
be used only when equivalent permissible equipment does not exist.
    (b) All nonpermissible battery operated IR equipment will be 
limited to:
    (i) Flir i50 7.2 volt Li/ion S/N 399002500.
    (ii) Flir E5 3.6 volt Li/ion S/N 63913354.
    (iii) Flir E5 3.6 volt Li/ion S/N 63917252.
    (4) Nonpermissible IR equipment will only be used until equivalent 
permissible IR is available.
    (5) A logbook will be maintained for electronic IR and will be kept 
in the mine office where the equipment is located. The logbook will 
contain the date of manufacture and/or purchase of each particular 
piece of electronic IR equipment and will be made available to MSHA on 
request.
    (6) All nonpermissible electronic IR equipment to be used in or 
inby the last open crosscut will be examined by the person that will 
operate the equipment, prior to taking the equipment underground to 
ensure the equipment is being maintained in a safe operating condition. 
These checks will include:
    (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.
    (vi) Recording the results of the inspection in the equipment 
logbook.
    (7) The equipment will be examined at least weekly by a qualified 
person as defined in 30 CFR 75.153. The examination results will be 
recorded weekly in the logbook. Inspection entries in the logbook may 
be expunged after one year.
    (8) All nonpermissible electronic IR equipment will be serviced 
according to the manufacturer's recommendations. Dates of service will 
be recorded in the equipment logbook and will include a description of 
the work performed.
    (9) The nonpermissible IR equipment that will be used in or inby 
the last open crosscut will not be put into service until MSHA has 
initially inspected the equipment and determined that it is in 
compliance.
    (10) Nonpermissible IR equipment will not be used if methane is 
detected in concentrations at or above one percent. When one percent or 
more of methane is detected while the nonpermissible IR equipment is 
being used, the equipment will be deenergized immediately and withdrawn 
outby the last open crosscut. Prior to returning inby the last open 
crosscut, all

[[Page 17504]]

requirements of 30 CFR 75.323 will be complied with.
    (11) As an additional safety check, prior to energizing 
nonpermissible IR equipment in or inby the last open crosscut, the 
operator of the equipment will conduct a visual examination of the 
immediate area for evidence that the area appears to be sufficiently 
rock dusted and for the presence of accumulated float coal dust. If the 
rock dusting appears insufficient or the presence of accumulated coal 
dust is observed, the equipment may not be energized until sufficient 
rock dust has been applied and/or the accumulations of coal dust have 
been cleaned up. If nonpermissible IR equipment is to be used in an 
area that is not rock dusted, within 40-feet of a working face where a 
continuous miner is used to extract coal, the area is to be rock dusted 
prior to energizing the electronic IR equipment.
    (12) All hand-held methane detectors will be MSHA-approved and 
maintained in permissible and proper operating condition as defined by 
30 CFR 75.320. All methane detectors must provide visual and audible 
warnings when methane is detected at or above one percent.
    (13) Prior to energizing the electronic IR equipment in or inby the 
last open crosscut, methane tests must be made no more than eight 
inches from the roof or floor in the area where the equipment is to be 
used.
    (14) All areas to be examined with nonpermissible IR equipment must 
be pre-shifted according to 30 CFR 75.360 prior to the IR examination. 
If the area is not pre-shifted a supplemental examination according to 
30 CFR 75.361 must be performed before any non-certified person enters 
the area. If the area has been examined according to 30 CFR 75.360 or 
75.361, an additional examination is not required.
    (15) A qualified person as defined in 30 CFR 75.151 will 
continuously monitor for methane immediately before and during the use 
of nonpermissible IR equipment in or inby the last open crosscut.
    (16) Batteries contained in the IR equipment must be changed out or 
charged in intake air outby the last open crosscut. Replacement 
batteries for the electronic IR equipment will not be brought in or 
inby the last open crosscut. Upon entry into the mine, all batteries 
for the electronic infrared equipment must be fully charged.
    (17) When using nonpermissible electronic IR equipment in or inby 
the last open crosscut the operator must confirm by measurement or by 
inquiry of the person in charge of the section that the air quantity on 
the section, on that shift, in the last open crosscut is the quantity 
that is required by the mine's ventilation plan.
    (18) Personnel engaged in the use of IR equipment will be properly 
trained to recognize the hazards and limitations associated with the 
use of the equipment in areas where methane could be present.
    (19) All persons who operate nonpermissible electronic IR equipment 
will receive specific training on the terms and conditions of this 
petition before using nonpermissible electronic equipment in or inby 
the last open crosscut. A record of the training will be kept with 
other training records.
    (20) Within 60 days after the proposed decision and order (PDO) 
becomes final, the petitioner will submit proposed revisions for their 
approved 30 CFR part 48 training plans to the District Manager. These 
revisions will specify initial and refresher training regarding the 
terms and conditions of the PDO. When training is conducted an MSHA 
Certificate of Training (Form 5000-23) will be completed. Comments on 
the certificate of training will indicate IR operator training.
    The petitioner asserts that the proposed alternative method will at 
all times guarantee no less than the same measure of protection 
afforded by the existing standard.

that:
    (1) The mines consist of both development and production headings. 
Activities include drilling, blasting, scaling, loading and hauling of 
ore.
    (2) The compressed air and bottled water will be used in proposed 
refuge areas located at various locations.
    (3) The mines currently use designated points of safety (DPOS) 
located throughout the mine for areas of safe refuge in case of an 
emergency. The DPOS contains compressed air with a regulator, bottled 
water, first aid supplies, maps and a phone.
    (4) As an alternative to compliance with the existing standard, Doe 
Run proposes the following:
    (a) The proposed refuge chambers will be constructed out of fire 
resistant material.
    (b) The door to the proposed refuge chambers will have at least a 
fire rating of one and one-half hours.
    (c) The chamber will be equipped with at minimum three compressed 
air bottles each containing 7,929 liters at 310 cubic feet of Grade D 
breathing air; a regulator to meter the air; a minimum of 15 gallons of 
bottled water; first aid kit; stretcher; six tubes of latex caulk to 
seal around the door; one fire extinguisher; and a set of escape maps 
and an escape plan.
    (d) A pager phone will be used for communication. The phone line 
servicing the phone will be a heavy jacketed, shielded line that runs 
from the main shop area to the refuge area, and a second line will be 
installed.
    (e) The refuge chambers will be equipped with a ball valve located 
on the wall to relieve pressure build up from the use of the compressed 
air inside the chambers.
    (f) Two benches will be located along the walls to provide seating 
for the miners.
    The petitioner asserts that the proposed alternative method will at 
all times guarantee no less than the same measure of protection 
afforded by the existing standard.
