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-2013-052-C.
    Petitioner: Rosebud Mining Company, P.O. Box 1025, Northern 
Cambria, Pennsylvania 15714.
    Mine: Brush Valley Mine, MSHA I.D. No. 36-09437, located in Indiana 
County, Pennsylvania.
    Regulation Affected: 30 CFR 75.503 (Permissible electric face 
equipment; maintenance), (18.35(a)(5)(i) (Portable (trailing) cables 
and cords)).
    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 1,200 feet when No. 2 American Wire Gauge (AWG) cable 
is used and 480-volt trailing cables with a maximum length of 950 feet 
when No. 4 AWG cable is used on roof bolters. The petitioner states 
that:
    (1) The maximum length for the trailing cable for the 480-volt roof 
bolters will be 1,200 feet when No. 2 AWG cable is being used. The 
maximum length of 480-volt trailing cable will be 950 feet when No. 4 
AWG cable is being used.
    (2) The trailing cable for the 480-volt bolters will not be smaller 
than No. 4 AWG cable.
    (3) All circuit breakers used to protect the No. 2 AWG trailing 
cable and 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 on these breakers cannot be changed, and these breakers 
will have permanent, legible labels. Each label will identify the 
circuit breaker as being suitable for protecting the cables.
    (4) Replacement circuit breakers and/or instantaneous trip units 
used to protect No. 2 or No. 4 AWG trailing cable will be calibrated to 
trip at 500 amperes and will be sealed.
    (5) All components that provide short-circuit protection will have 
a sufficient interruption rating in accordance with the maximum 
calculated fault currents available.
    (6) During each production day, the trailing cables and circuit 
breakers will be examined in accordance with all 30 CFR provisions.
    (7) Permanent warning labels will be installed and maintained on 
the load center to identify the location of each short-circuit 
protection device. These labels will warn miners not to change or alter 
the settings of these devices.
    (8) If the affected trailing cables are damaged in any way during 
the shift, the cable will be deenergized and repairs made.
    (9) The petitioner's 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 proper training as to the 
performance of their duties.
    (10) 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) The hazards of setting the short-circuit 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 for protecting the 
trailing cables against damage.
    (d) Proper procedures for examining the trailing cables to ensure 
safe operating condition by visual inspection of the entire cable, 
observing the insulation and the integrity of the splices, and 
examining nicks and abrasions.
    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 afforded by 
the existing standard.
    Docket Number: M-2013-053-C.
    Petitioner: White Buck Coal Company, P.O. Box 190, Leivasy, West 
Virginia 26676.
    Mine: Grassy Creek No. 1 Mine, MSHA I.D. No. 46-08365, located in 
Nicholas County, West Virginia.
    Regulation Affected: 30 CFR 75.1405 (Automatic couplers).
    Modification Request: The petitioner requests a modification of the 
existing standard that requires haulage equipment to be provided with 
automatic couplers, which couple by impact and uncouple without the 
necessity of persons going between the ends of such equipment. The 
petitioner states that:
    1. Mine cars and locomotives will not be coupled or uncoupled while 
in motion.
    2. Tow bars, safety chains, and connecting pins of sufficient size 
and strength will be installed in lieu of the automatic couplers.
    3. Connecting pins used to secure tow bars to mine cars or 
locomotives will be secured in a manner that pins will not become 
disengaged from mine cars or locomotives while in motion.
    4. Supply cars will stay coupled to each other by means of a tow 
bar, safety chains, and locking pins at all times.
    5. Chock blocks or other devices will be used to prevent movement 
of the cars during coupling and uncoupling.
    6. Mine cars or locomotives will be coupled by means of tow bars 
with jack attachments.

[[Page 78392]]

    7. An attached jack will support the tow bar during coupling or 
uncoupling.
    8. Mine personnel will use a rod, provided with the jack, of 
sufficient length to raise or lower the tow bar and maintain a safe 
distance from pinch points.
    9. Mine personnel will attach the draw bar to the motor by a lever 
with a connecting pin attached. This will be done away from pinch 
points between the car and locomotive.
    10. Mine personnel will not place themselves between cars while the 
cars are being coupled or uncoupled.
    11. The petitioner further states that the purposes of the existing 
standard are to provide protection for miners from placing themselves 
in pinch points or danger zones while coupling cars, and to provide 
protection against cars becoming uncoupled and becoming an uncontrolled 
hazard. The alternative method of compliance guarantees protection from 
these hazards by: (a) Still requiring that no coupling/uncoupling 
activities take place with miners in between cars, and (b) using 
redundant systems (tow bars, safety chains, and locking pins) to 
prevent runaway cars.
    Within 60 days after the Proposed Decision and Order (PDO) becomes 
final, the Petitioner will submit proposed revisions for its approved 
30 CFR part 48 training plan to the District Manager. These proposed 
revisions will specify initial and refresher training regarding the 
terms and conditions stated in the PDO.
    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.
    Docket Number: M-2013-054-C.
    Petitioner: Peabody Midwest Mining, LLC, Three Gateway Center, 
suite 1500, 401 Liberty Avenue, Pittsburgh, Pennsylvania 15222-1000.
    Mine: Wildcat Hills Underground Mine, MSHA I.D. No. 11-03156, 
located in Saline County, Illinois.
    Regulation Affected: 30 CFR 75.1700 (Oil and gas wells).
    Modification Request: The petitioner requests a modification of the 
existing standard to permit an alternative method of compliance with 
respect to mining through oil and gas wells. The petitioner projects 
that a number of oil wells are within the boundaries of the mine and, 
based on current mine projections, most of these wells will be plugged 
and mined through over the productive life of the mine.
    a. The petitioner proposes to use the following procedures when 
cleaning out and preparing oil and gas wells prior to plugging:
    (1) A diligent effort will be made to clean the borehole to the 
original total depth. If this depth cannot be reached, the borehole 
will be cleaned out to a depth to permit the placement of at least 200 
feet of expanding cement below the base of the lowest mineable coalbed.
    (2) When cleaning the borehole, a diligent effort will be made to 
remove all of the casing in the borehole. If it is not possible to 
remove all of the casing, the casing which remains will be perforated, 
or ripped, at intervals spaced close enough to permit expanding cement 
slurry to infiltrate the annulus between the casing and the borehole 
wall for a distance of at least 200 feet below the base of the lowest 
mineable coalbed.
    (3) Place a mechanical bridge plug in the well if a cleaned-out 
borehole produces gas. Place the mechanical bridge plug in a competent 
stratum at least 200 feet below the base of the lowest mineable 
coalbed, but above the top of the uppermost hydrocarbon-producing 
stratum. If it is not possible to set a mechanical bridge plug, a 
substantial brush plug may be used in place of the mechanical bridge 
plug.
    (4) A suite of logs will be made consisting of a caliper survey, 
directional deviation survey, and log(s) suitable for determining the 
top and bottom of the mineable coalbeds and potential hydrocarbon-
producing strata and the location for a bridge plug.
    (5) If the uppermost hydrocarbon-producing stratum from the 
expanding cement plug is within 200 feet of the base of the lowest 
mineable coalbed, properly placed mechanical bridge plugs or a suitable 
brush plug will be used to isolate the hydrocarbon producing stratum 
from the expanding cement plug. Nevertheless, a minimum of 200 feet of 
expanding cement will be placed below the lowest mineable coalbed.
    (6) The wellbore will be completely filled and circulated with a 
gel that inhibits any flow of gas, supports the walls of the borehole, 
and increases the density of the expanding cement. This gel will be 
pumped through open-end tubing run to a point approximately 20 feet 
above the bottom of the cleaned out area of the borehole or bridge 
plug.
    b. The petitioner will use the following procedures when plugging 
or replugging gas or oil wells to the surface:
    (1) A cement plug will be set in the wellbore by pumping expanding 
cement slurry down the tubing to displace the gel and fill the borehole 
to the surface. (As an alternative, the cement slurry may be pumped 
down the tubing so that the borehole is filled with Portland cement or 
a Portland cement-fly ash mixture from a point approximately 100 feet 
above the top of the lowest mineable coalbed to the surface with an 
expanding cement plug extending from at least 200 feet below the lowest 
mineable coalbed to the bottom of the Portland cement). There will be 
at least 200 feet of expanding cement below the base of the lowest 
mineable coalbed.
    (2) Embed a surface casing, small quantity of steel turnings, or, 
other small magnetic particles in the top of the cement near the 
surface to serve as a permanent magnetic monument of the borehole. As 
an alternative, a steel rod may be driven into the ground next to the 
borehole.
    c. The petitioner proposes to use the following procedures when 
using the vent pipe method for plugging oil or gas wells:
    (1) Run a 4\1/2\-inch or larger vent pipe into the wellbore to a 
depth of 100 feet below the lowest mineable coalbed and swedged to a 
smaller diameter pipe, if desired, that will extend to a point 
approximately 20 feet above the bottom of the cleaned out area of the 
borehole or bridge plug.
    (2) Set a cement plug in the wellbore by pumping an expanding 
cement slurry, Portland cement, or a Portland cement-fly ash mixture 
down the tubing to displace the gel so that the borehole is filled with 
cement. Fill the borehole and the vent pipe with expanding cement for 
minimum of 200 feet below the base of the lowest mineable coalbed. The 
top of the expanding cement will extend upward to a point approximately 
100 feet above the top of the highest mineable coalbed.
    (3) Evacuate all fluid from the vent pipe to facilitate testing of 
gases. During the evacuation of fluid, the expanding cement will not be 
disturbed.
    (4) Protect the top of the vent pipe to prevent liquids or solids 
from entering the wellbore, but permit ready access to the full 
internal diameter of the vent pipe when necessary.
    d. The petitioner proposes to use the following cut-through 
procedures whenever the safety barrier diameter is reduced to a 
distance less than the District Manager (DM) would approve pursuant the 
30 CFR 75.1700 or proceeds with an intent to cut through a plugged 
well:
    (1) Prior to reducing the safety barrier to a distance less than 
the DM would approve pursuant to 30 CFR 75.1700 or proceeding with an 
intent to cut through a plugged well, the operator will notify the DM 
or his/her designee.

[[Page 78393]]

    (2) The DM or designee may conduct a conference prior to mining 
through any plugged well to review and approve the specific procedures 
for mining through the well. Representatives of the operator, the 
representative of miners, and the appropriate State agency will be 
informed within a reasonable time prior to the conference, and be given 
an opportunity to attend and participate. This meeting may be called by 
the operator.
    (3) Mining in close proximity to or through a plugged well will be 
done on a shift approved by the DM or designee.
    (4) Notify the DM or designee, representative of the miners, and 
the appropriate State agency in sufficient time prior to the mining 
through operation to have an opportunity to have representatives 
present.
    (5) When using continuous mining equipment, install drivage sights 
at the last open crosscut near the place to be mined to ensure 
intersection of the well. The drivage sights will not be more than 50 
feet from the well. If longwall mining methods are later used, install 
drivage sights on 10-foot centers for a distance of 50 feet in advance 
of the wellbore. The drivage sights will be installed in the headgate 
and tailgate.
    (6) Firefighting equipment, including fire extinguishers, rock 
dust, and sufficient fire hose to reach the working face area of the 
mine-through will be available when either the conventional or 
continuous mining method is used. Locate the fire hose in the last open 
crosscut of the entry or room. All fire hoses will be ready for 
operation during the mining through.
    (7) Sufficient supplies of roof support and ventilation materials 
will be available and located at the last open crosscut. In addition, 
an emergency plug and/or plugs will be available in the immediate area 
of the cut-through.
    (8) Maintain at least the quantity of air required by the approved 
mine ventilation plan, but not less than 6,000 cubic feet of air per 
minute for scrubber equipped continuous miners or not less than 9,000 
cubic feet per minute for continuous miner sections using auxiliary 
fans or line brattice only, to ventilate the working face during the 
mine-through operation. The quantity of air required by the ventilation 
plan, but not less than 30,000 cfm, will reach the working face of each 
future longwall during the mine-through operation.
    (9) Check equipment for permissibility and service on the shift 
prior to mining through the well and maintain the water line to the 
tail piece with a sufficient amount of fire hose to reach the farthest 
point of penetration on the section.
    (10) Calibrate methane monitor(s) on the continuous mining machine 
or the longwall shear and face on the shift prior to mining through the 
well.
    (11) When mining is in progress, test methane levels with a hand-
held methane detector at least every 10 minutes from the time that 
mining with the continuous mining machine is within 20 feet of the well 
until the well is intersected and immediately prior to mining through 
it or from the time that mining with longwall mining equipment is 
within 10 feet of the well. No individual is allowed on the return side 
during the actual cutting process until the mine-through has been 
completed and the area examined and declared safe.
    (12) Keep the working place free from accumulations of coal dust 
and coal spillages, and place rock dust on the roof, rib, and floor to 
within 20 feet of the face when mining through the well when using 
continuous or conventional mining methods. Conduct rock dusting on 
longwall sections on the roof, rib, and floor up to both the headgate 
and tailgate gob.
    (13) Deenergize all equipment when the wellbore is intersected and 
thoroughly examine the place and determined it safe before resuming 
mining. No open flame is permitted in the area until adequate 
ventilation has been established around the wellbore.
    (14) After a well has been intersected and the working place 
determined safe, mining will continue inby the well a sufficient 
distance to permit adequate ventilation around the area of the 
wellbore.
    (15) No person will be permitted in the area of the cut-through 
operation except those actually engaged in the mining operation, mine 
management, representative of the miners, personnel from MSHA, and 
personnel from the appropriate State agency.
    (16) Mining will be coordinated by a responsible person as defined 
in 30 CFR 75.1501.
    (17) A certified official will directly supervise the mining-
through operation and only the certified official in charge will issue 
instructions concerning the mining-through operation.
    (18) MSHA personnel may interrupt or halt the mining-through 
operation when it is necessary for the safety of the miners.
    (19) A copy of the petition will be maintained at the mine and be 
available to the miners.
    (20) The petitioner will file a plugging affidavit stating the 
persons who participated in the work, a description of the plugging 
work, and a certification by the petitioner that the well has been 
plugged.
    (21) Unless the existing records show that an abandoned well was 
plugged using techniques equivalent to the proposed decision and orders 
terms and condition, and that information is submitted and accepted in 
accordance as providing the required level of safety by the DM, the 
well will again be cleaned, inadequate plugging materials drilled out 
and the well plugged in accordance with the terms and conditions of the 
proposed decision and order before such wells may be cut through or 
approached within the allowed limits. Securing and interpreting the 
suite of drill logs is needed to ensure that, at a minimum, the 
expanding cement plug extends from at least 200 feet below the lowest 
mineable seam through 100 feet above the highest mineable seam, unless 
the seams are separated by an interval greater than 300 feet, in which 
case, each seam may be plugged individually.
    Within 60 days after this petition becomes final, the petitioner 
will submit proposed revisions for its approved part 48 training plan 
to the DM. These proposed revisions will include initial and refresher 
training regarding compliance with the terms and conditions stated in 
the proposed decision and order.
    The petitioner asserts that the proposed alternative method will at 
all times guarantee no less than the same measure or protection 
afforded by the existing standard.
