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-2014-018-C.
    Petitioner: S & J Coal Mine, Inc., 15 Motter Drive, Pine Grove, 
Pennsylvania 17963.
    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 the use of nonpermissible electric drags 
and battery locomotives within 150 feet of pillar workings. The 
petitioner asserts that 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 tests results to be recorded in the on-shift 
examination record. The petitioner states that:
    (1) Equipment operation will be suspended any time methane 
concentration at the equipment reaches 0.5 percent either during 
operation or when found during a pre-shift examination.
    (2) The equipment will be operated in the working section's only 
intake entry (gangway), which is regularly traveled and examined.
    (3) The use of drags on less than moderate pitching veins (less 
than 20 degree pitch) is the only practical system of mining in use.
    (4) Permissible drags are not commercially available, and due in 
part to their small size, permissible locomotives are not commercially 
available.
    (5) 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.

[[Page 36562]]

    (6) 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 minable pillars are recovered from 
the deepest point of penetration outby.
    (7) The 5,000 cubic feet per minute of required intake air flow is 
measured just outby the nonpermissible equipment with the ventilating 
air passing over the equipment to ventilate the pillar being mined.
    (8) The electrical equipment is attended during operation, and 
either power to the unit is deenergized at the intersection of the 
working gangway and intake slope, or the equipment is moved to that 
area when production ceases, minimizing any ignition potential from the 
pillar recovery area.
    (9) Where more than one active line of pillar breast 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 
provide the same measure of protection as that afforded by the existing 
standard.
    Docket Number: M-2014-019-C.
    Petitioner: The M-Class Coal Company, 11351 North Thompsonville 
Road, Macedonia, Illinois 62860.
    Mine: M-Class Mine, MSHA I.D. No. 11-03189, located in Franklin 
County, Illinois.
    Regulation Affected: 30 CFR 75.1909(b)(6) (Nonpermissible diesel-
powered equipment; design and performance requirements).
    Modification Request: The petitioner requests a modification of the 
existing standard to permit an alternative method of compliance with 
respect to the braking systems on the Getman RDG-1504 Road Builder. The 
petitioner proposes to operate the Road Builder, Serial Number 7059, as 
it was originally designed without brakes. The petitioner states that:
    (1) The standard does not address equipment with more than four 
wheels, specifically the Getman RDG-1504 Road Builder with six wheels. 
This machine has dual brake systems on the four rear wheels and is 
designed to prevent a loss of braking due to a single component 
failure.
    (2) Seventy-four percent of the machine's total weight is over the 
four rear wheels. With the weight distribution, brakes on the rear of 
the machine are sufficient to safely stop the machine.
    (3) Grader operators will be trained to lower the moldboard for 
additional stopping capability in emergency situations.
    (4) Operators will be trained to recognize the appropriate speeds 
to use on different roadway conditions.
    (5) The speed of the machine will be limited to 10 miles per hour.
    (6) The safety of the miners will not be compromised if the machine 
is operated as described above.
    The petitioner asserts that the proposed alternative method will 
guarantee the same measure of protection to the miners as the existing 
standard.
    Docket Number: M-2014-004-M.
    Petitioner: FMC Minerals Corporation, Box 872, Green River, Wyoming 
82935.
    Mine: FMC Westvaco Mine, MSHA I.D. No. 48-00152, located in 
Sweetwater County, Wyoming.
    Regulation Affected: 30 CFR 57.22305 (Approved equipment (III 
mines)).
    Modification Request: The petitioner requests a modification of the 
existing standard to permit a submersible mine pump installed and 
operated through a borehole from the surface to be operated in a 
flooded area of the mine.
    The petitioner states that this modification involves operating a 
non-permissible pump in an area of the mine, which was previously a 
shortwall panel.
    If additional pumps need to be installed in mine return airways in 
the future, the petitioner proposes to follow the requirements of this 
modification.
    The depth of the new well will depend on the pump style, casing, 
and net positive suction head required. The pump will be monitored by a 
motor controller designed for submersible pumps. The existing well and 
submersible pump installation at the Granger operation uses a protector 
unit located between the motor and pump that isolates the motor and 
equalizes pressure, negating the possibility that the oil will leak 
from the motor. The pumps are used to pump oil, gas, and propane 
without any other safety systems. A similar pump will be used for the 
FMC Westvaco Mine.
    The petitioner asserts that because the trona mining environment 
does not have the inherent safety hazards of coal mining, the 
requirements from the Granger operation pump modification should 
provide equivalent safety measures for the Westvaco submersible pump 
application.
    The intent for installation of the pump is to recover trona 
resources and maintain production in the petitioner's ELDM plant. 
Solution mining allows trona resources to be safely recovered from the 
surface without using underground miners to extract the trona. The 
petitioner asserts that after reviewing the Mine Pump Approval Lists 
from the MSHA Approval and Certification Center, they did not find a 
permissible pump that will meet the process requirements for this 
application. The petitioner states that:
    (1) The high-voltage three-phase alternating current electric power 
circuit for the pumps will be designed and installed to:
    (a) Contain either a direct or derived neutral that will be 
grounded through a suitable resistor at the source transformer or power 
center. A grounding circuit originating at the grounded side of the 
grounding resistor will extend along with the power conductors and 
serve as the grounding conductor for the frame of the pumps and all 
associated electric equipment that may be supplied power from this 
circuit. Power will not be supplied to any other equipment from this 
circuit.
    (b) Contain a grounding resistor that limits the ground-fault 
current to not more than 15 amperes. The grounding resistor will be 
rated for the maximum fault current available and will be insulated 
from the ground for a voltage equal to the phase-to-phase voltage of 
the system.
    (c) Contain a suitable circuit breaker or vacuum contactor of 
adequate interrupting with devices to provide protection against under-
voltage, grounding phases, short-circuit and overload.
    (d) Contain a disconnecting device installed in conjunction with 
the circuit breaker to provide visual evidence that all power is 
disconnected from the pump.
    (e) Include a fail-safe ground check circuit or other no less 
effective device approved by MSHA as required by 30 CFR 57.12028, that 
will cause the circuit breaker to open when either the ground or the 
ground check wire is broken.
    (f) Contain a low resistance grounding medium for grounding of the 
lightning arrestor(s) of the high voltage power circuits of the pump(s) 
that is separated from the pump power neutral power circuit by a 
distance of no less than 25 feet.
    (g) Protect all associated equipment with this pump on the surface 
of the mine from dust, rain, and rodents by a suitable enclosure.
    (2) The electric control circuit for the pump will be designed and 
installed to:
    (a) Maintain the electric connections of the pump and pump motor 
under 3 feet of water at all times.
    (b) Automatically deenergize the pump motor when the water level 
falls below 3 feet at the pump location.

[[Page 36563]]

    (c) Prevent the restarting of the pump motor at any time the water 
level is below 3 feet at the pump location.
    (3) The pump installation will be equipped with a water level 
indicator located at the pump electrical controls so that the water 
level at the pump can be determined before the pump motor is restarted.
    (4) All high- and low-water probes and float circuits associated 
with the pump will be MSHA-accepted intrinsically safe, and will be 
installed and maintained in accordance with MSHA acceptance.
    (5) All surface installed equipment associated with the pump will 
be accessible for inspection.
    (6) A functional test will be conducted weekly for the grounded-
phase protective device(s) to determine if it is operating properly. A 
record of the tests will be kept for one year and will be made 
available for review by MSHA.
    (7) Before installation and operation of any future pumps, not 
including replacement pump(s) for the pump in this proposed petition, 
the petitioner will notify the District Manager for approval prior to 
installation and operation.
    (8) Implementation of the proposed decision and order will not 
begin until MSHA has conducted an inspection of the pump and associated 
electrical installation to ensure that the terms and conditions of the 
decision have been complied with.
    (9) Within 60 days after this petition for modification is granted, 
the petitioner will submit to the District Manager proposed revisions 
for the approved 30 CFR part 48 training plan that will specify task 
training for all electricians who perform electric work on this pump. 
The training will include instructions in the following elements:
    (a) Hazards that could exist if the water level falls below the 
electric connections of the pumps and pump motor; and
    (b) Safe pump restart procedures when the water is 3 feet above the 
electric components and pump motor.
    The petitioner asserts that adhering to the proposed requirements 
in this petition for modification will guarantee the same measure of 
protection as the existing standard.
