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-2016-031-C.
Petitioner: S & J Coal Mine, 15 Motter Drive, Pine Grove,
Pennsylvania 17963-8854.
Mine: Slope #2 Mine, MSHA I.D. No. 36-09963, located in Schuylkill
County, Pennsylvania.
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 use of nonpermissible electric equipment
within 150 feet of the pillar line to include drags and battery
locomotives. The request is due in part to the method of mining used in
pitching anthracite mines and the alternative evaluation of the mine
air quality for methane on an hourly basis during operation, with one
of the gas test results to be recorded in the on-shift examination
record. The petitioner also proposes to suspend equipment operation any
time methane concentration at the equipment reaches 0.5 percent methane
either during operation or when found during a preshift examination.
The petitioner states that:
(1) The equipment will be operated in the working section's only
intake entry (gangway), which is regularly traveled and examined.
(2) The use of drags on less than moderate pitching veins (less
than 20 degrees pitch) is the only practical system of mining in use.
(3) Permissible drags are not commercially available, and due in
part to their small size, permissible locomotives are not commercially
available either.
(4) As a result of low daily production rates and full timbering
support, in-rushes of methane due to massive pillar falls are unlikely
to occur.
(5) Recovery of the pillars above the first miner heading is
usually accomplished on the advance within 150 feet of the section
intake (gangway) and the remaining mineable pillars recovered from the
deepest point of penetration outby.
(6) The 5,000 cubic feet per minute of required intake airflow is
measured just outby the nonpermissible equipment with the ventilating
air passing over the equipment to ventilate the pillar being mined.
(7) The electrical equipment is attended during operation and
either power to the unit deenergized at the intersection of the working
gangway and intake slope or equipment moved to that area when
production ceases, minimizing any ignition potential from the pillar
recovery area.
(8) Where more than one active line of pillar breasts recovery
exists, the locomotive may travel to a point just outby the deepest
active chute/breast (room) workings or last open crosscut in a
developing set of entries.
The petitioner asserts that the proposed alternative method will at
all times guarantee no less than the same
[[Page 81811]]
measure of protection to the miners as would be provided by the
existing standard.
Docket Number: M-2016-032-C.
Petitioner: S & J Coal Mine, 15 Motter Drive, Pine Grove,
Pennsylvania 17963-8854.
Mine: Slope #2 Mine, MSHA I.D. No. 36-09963, located in Schuylkill
County, Pennsylvania.
Regulation Affected: 30 CFR 75.1400 (Hoisting equipment; general).
Modification Request: The petitioner seeks to permit the use of a
gunboat to transport persons without safety catches or other no less
effective devices because to date, no such safety catch or device is
available for steeply pitching and undulating slopes with numerous
curves and knuckles present in the main haulage slopes of anthracite
mines. The mines range in length from 30 to 4,200 feet and vary in
pitch from 12 degrees and 75 degrees. The petitioner states that:
(1) A functional safety catch has not been developed. Makeshift
devices, if installed, would be activated on knuckles and curves when
no emergency exists causing a tumbling effect on the conveyance, which
would increase rather than decrease the hazard to miners.
(2) As an alternative, the petitioner proposes to operate the man-
cage or steel gunboat with secondary safety connections securely
fastened around the gunboat and to the hoisting rope above the main
connecting device, and use hoisting ropes having a factor of safety in
excess of the 4 to 8 to 1 as suggested in the American Standards
Specifications for Use of Wire Ropes for Mines.
The petitioner asserts that the proposed alternative method will
provide no less than the same measure of protection afforded the miners
under the existing standard.
Docket Number: M-2016-033-C.
Petitioner: Mach Mining, LLC, P.O. Box 300, Johnston City, Illinois
62951.
Mine: Mach No. 1 Mine, MSHA I.D. No. 11-03141, located in
Williamson County, Illinois.
Regulation Affected: 30 CFR 75.503 (Permissible electric face
equipment; maintenance) and 30 CFR 18.35 (Portable trailing cables and
cords).
Modification Request: The petitioner requests a modification of the
existing standard to allow the use of trailing cables longer than
permitted under the existing standard. The petitioner states that:
(1) The maximum lengths of the 995-volt trailing cables will be
1,000 feet and not smaller than No. 2 American Wire Gauge (AWG).
(2) All circuit breakers used to protect No. 2 AWG trailing cables
exceeding 700 feet in length will have instantaneous trip units
calibrated to trip at 800 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 cables. The labels will be maintained legible.
(3) Replacement instantaneous trip units used to protect No. 2 AWG
trailing cables will be calibrated to trip at 800 amperes, and this
setting will be sealed and locked.
(4) All components that provide short-circuit protection will have
a sufficient interruption rating in accordance with the maximum
calculated fault currents available.
(5) Short-circuit settings must not exceed the setting specified in
the approval documentation or 70 percent of the maximum available
current, whichever is less.
(6) Any trailing cable that is not in safe operating condition will
be removed from service immediately and repaired or replaced.
(7) Each splice or repair in the trailing cable will be made in a
workmanlike manner and in accordance with the instructions of the
manufacturer of the splice or repair kit. The outer jacket of each
splice or repair will be vulcanized with flame-resistant material or
made with material that has been accepted by MSHA as flame resistant.
(8) In the event the mining methods or operating procedures cause
or contribute to the damage of any trailing cable, the trailing cable
will be removed from service immediately and repaired or replaced, and
additional precautions will be taken to ensure that in the future, the
cable is protected and maintained in safe operating condition.
(9) During each production day, persons designated by the mine
operator will visually examine the trailing cables to ensure that the
cables are in safe operating condition. The instantaneous settings of
the specially calibrated circuit breakers will be visually examined to
ensure that the seals or locks have not been removed and do not exceed
the settings stipulated in items (2) and (3).
(10) Permanent warning labels will be installed and maintained on
the cover of the power center identifying the location of each sealed
short-circuit protective device. These labels will warn miners not to
change or alter these sealed short-circuit settings.
(11) The alternative method will not be implemented until all
miners who have been designated to examine the integrity of seals or
locks, verify the short-circuit settings, and examine trailing cables
for defects have received their training.
(12) 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 for the area in
which the mine is located. The training will include the following
elements:
(a) Mining methods and operating procedures that will protect the
trailing cables against damage;
(b) Proper procedures for examining the trailing cables to ensure
that the cables are in safe operating condition;
(c) The hazards of setting the short circuit interrupting device
too high to adequately protect the trailing cables; and
(d) How to verify that the circuit interrupting device(s)
protecting the trailing cable(s) are properly set and maintained.
The procedures as specified in 30 CFR 48.3 for approval of proposed
revisions to already approved training plans will apply.
The petitioner asserts that the proposed alternative method will at
all times guarantee no less than the same measure of protection to the
miners as would be provided by the existing standard.
Docket Number: M-2016-034-C.
Petitioner: Warrior Coal, LLC, 57 J.E. Ellis Rd., Madisonville,
Kentucky 42431.

(4) Nonpermissible electronic testing and diagnostic equipment will
not be used if methane is detected in concentrations at or above 1.0
percent. When 1.0 percent or more methane is detected while the
nonpermissible electronic equipment is being used, the equipment will
be deenergized immediately and withdrawn outby the last open crosscut.
(5) All hand-held methane detectors will be MSHA-approved and
maintained in permissible and proper operating condition as defined in
30 CFR 75.320.
(6) Except for time necessary to troubleshoot under actual mining
conditions, coal production on MMU will cease. However, coal may remain
in or on the equipment to test and diagnose the equipment under
``load.''
(7) All electronic testing and diagnostic equipment will be used in
accordance with the manufacturer's recommendations.
