Download as PDF Federal Register / Vol. 79, No. 210 / Thursday, October 30, 2014 / Notices tkelley on DSK3SPTVN1PROD with NOTICES (1) The Clover Fork fan can be monitored for operation at the Huff Creek Communication Center. (2) Huff Creek Mine Communication Center personnel are present at all times when miners are underground. (3) If there is an interruption in the fan operation, a notification from the Huff Creek Communication Center can be given to the miners underground at Clover Fork mine. (4) Fan alarm signal monitoring by the Huff Creek Mine Communication Center is accomplished in two ways, first by fan signal connection to mine phones, and by a fiber optic line that is running from Clover Fork mine to the Huff Creek mine. (5) The fiber optic line is connected to the CO monitoring and tracking system computer at Clover Fork mine which receives an input from the fan alarm signal device. The fiber optic line terminates at a computer in the Communication Center and provides both audible and visual notification if the Clover Fork fan stops operating. (6) Voice communication to the Clover Fork mine is accomplished by three separate connections and also by wireless tracking system radios. Primary communication is by a mine phone line running through Huff Creek mine along A-Main entries to the borehole connection between the mines. (7) Backup to the mine phone system is an overland copper pair for the emergency phone system provided by the land line telephone company. A third way of communication to the mine is by land line telephone to the mine office. Tracking system radios provide a fourth means of communication. (8) In the event that the monitoring system for the fan should fail at the Huff Creek Mine Communication Center, Clover Fork mine management will provide personnel to monitor the fan operation at the mine site until repairs are made to the Huff Creek Mine Communication Center system. The petitioner asserts that the proposed alternative method provides the same level of protection to all miners as provided by the existing standard. Dated: October 24, 2014.

(4) The pump(s) electric control circuits will be designed and installed so that: (a) The pump(s) cannot start and/or run in either the manual or the automatic mode if the water is below the low level indicator (probe or bubbler) level. (b) The low level (probe or bubbler) water level probe will be located at least three feet above the pump inlet and motor and electrical connections of the pump(s). (c) The high and low water probes must be suitable for submersible pump control application. (d) All water level probe circuits will be protected with MSHA approved intrinsically safe barriers. (e) A remote control and monitoring system may be used with the pump system for condition monitoring and for remote start-up and shutdown control of the pumps. The remote control and monitoring system will not allow remote reset of the pump power system when fault conditions (e.g., grounded phase, short circuit, or overload) exist on the system. (5) The surface pump(s) control and power circuits will be examined, tested, and maintained as required by 30 CFR 77.502. (6) Splices and connections made in submersible pump cable will be made in a workmanlike manner and will meet the requirements of 30 CFR 75.604.

to already approved training plans will apply.
    The petitioner states that:
    (1) In the execution of work providing a blind drilled shaft for 
the mine operator the blind drilled shaft remains full of water and 
personnel are never required to go below the collar of the blind 
drilled shaft.
    (2) Water will be removed from the blind drilled shaft 
installations upon completion of the work and prior to the mine 
operator connecting the blind drilled shaft to the underground mine.
    (3) The blind drilled shaft is fully lined with steel casing and is 
grouted in place. This steel casing and grout seal isolate the 
completed blind drilled shaft from any coal seams, mitigating any 
possibility for methane to enter the blind drilled shaft.
    (4) The electric motor of any submersible pump is located below the 
pump intake making it impossible for the motor to ever be above the 
surface of the water.
    (5) There are no electric submersible motor/pump assemblies 
manufactured that will effectively pump water deeper than approximately 
400 feet that are permissible as required in 30 CFR 77.1914(a).
    (6) The petitioner proposes to use permissible pumps to dewater 
blind drilled shafts where depths are less than approximately 400 feet.
    (7) At depths greater than approximately 400 feet, the alternative 
method outlined in this petition is consistent with prudent engineering 
design pursuant to 30 CFR 77.1900

[[Page 64627]]

whereas it minimizes the hazards to those employed in the initial or 
subsequent development of the blind drilled shaft.
    The petitioner asserts that the proposed alternative method will at 
all times guarantee no less than the same measure of protection 
afforded the miners by the existing standard.

    Docket Number: M-2014-030-C.
    Petitioner: M-Class Mining, LLC, 11351 N. Thompsonville Road, 
Macedonia, Illinois 62860.
    Mine: MC#1 Mine, MSHA I.D. No. 11-03189, located in Franklin 
County, Illinois.
    Regulation Affected: 30 CFR 75.507-1(a) (Electric equipment other 
than power-connection points; outby the last open crosscut return air; 
permissibility requirements).
    Modification Request: The petitioner requests a modification of the 
existing standard to permit the use of nonpermissible submersible deep 
well pumps in bleeder and return air courses. The petitioner proposes 
to install low-voltage alternating current submersible pumps in return 
and/or bleeder entries and sealed area of the MC#1Mine. The petitioner 
states that:
    (1) These low-voltage submersible pumps will provide a pumping 
option to the existing turbine pumps that are installed to maintain the 
bleeder and return entries from obstructions caused by water. Water 
accumulations in these airways can pose a safety hazard as they can 
affect the airflow in the active and inactive parts of the mine.
    (2) The pumps may be installed between 600 and 1,200 feet below the 
surface.
    (3) The three-phase low-voltage alternating current electric power 
circuits for the pumps will be designed and installed to:
    (a) Contain either a direct or derived neutral wire, which must be 
grounded through a suitable resistor at the source transformer or power 
center and through a grounding circuit originating at the grounded side 
of the grounding resistor, which must extend along with the power 
conductors and serve as the grounding conductor for the frame of the 
pump and all associated electric equipment that may be supplied power 
from this circuit. The borehole casing will be bonded to the system 
grounded medium.
    (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 ground for a voltage equal to the phase-to-phase voltage of the 
system.
    (c) Provide protection by a suitable circuit breaker of adequate 
interrupting capacity with devices to protect against undervoltage, 
grounded phase, short-circuit, and overload.
    (d) Contain a disconnecting device installed in conjunction with 
the circuit breaker to provide visual evidence that the power is 
disconnected.
    (e) Include a fail-safe ground check circuit or other no less 
effective device approved by the Secretary as required by 30 CFR 
75.902, that will cause the circuit breaker to open when either the 
ground or pilot wire is broken.
    (4) The pump(s) electric control circuits will be designed and 
installed so that:
    (a) The pump(s) cannot start and/or run in either the manual or the 
automatic mode if the water is below the low level indicator (probe or 
bubbler) level.
    (b) The low level (probe or bubbler) water level probe will be 
located at least three feet above the pump inlet and motor and 
electrical connections of the pump(s).
    (c) The high and low water probes must be suitable for submersible 
pump control application.
    (d) All water level probe circuits will be protected with MSHA 
approved intrinsically safe barriers.
    (e) A remote control and monitoring system may be used with the 
pump system for condition monitoring and for remote start-up and 
shutdown control of the pumps. The remote control and monitoring system 
will not allow remote reset of the pump power system when fault 
conditions (e.g., grounded phase, short circuit, or overload) exist on 
the system.
    (5) The surface pump(s) control and power circuits will be 
examined, tested, and maintained as required by 30 CFR 77.502.
    (6) Splices and connections made in submersible pump cable will be 
made in a workmanlike manner and will meet the requirements of 30 CFR 
75.604. The pump installations will comply with all other applicable 30 
CFR requirements.
    (7) Within 60 days after the Proposed Decision and Order becomes 
final, the petitioner will submit proposed revisions for its approved 
part 48 training plan to the District Manager. The proposed revisions 
will specify task training for all qualified electricians who perform 
electric work and monthly electric examinations, testing and 
maintenance as required in 30 CFR 77.502, refresher training regarding 
the alternative method outlined in the petition, and the terms and 
conditions in the Proposed Decision and Order.
    (8) The procedures of 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 
afforded the miners by the existing standard.
