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 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-2009-059-C.
Petitioner: McClane Canyon Mining, P.O. Box 98, Loma, Colorado
81524.
Mine: McClane Canyon Mine, MSHA I.D. No. 05-03013, located in
Garfield County, Colorado.
Regulation Affected: 30 CFR 75.1101-1(b) (Deluge-type water spray
systems).
Modification Request: The petitioner requests a modification of the
existing standard to permit an alternative method of compliance in lieu
of using blow-off dust covers for nozzles of a deluge-type water spray
system. The petitioner states that: (A) A person trained in testing
procedures specific to the deluge-type water spray fire suppression
systems utilized at each belt drive will once each week: (1) Conduct a
visual examination of each of the deluge-type water spray fire
suppression systems; (2) conduct a functional test of the deluge-type
water spray fire suppression systems by actuating the system and
observing its performance; and (3) record the results of the
examination and functional test in a book maintained on the surface for
that purpose. The record will be made available to the authorized
representative of the Secretary and retained at the mine for one year;
(B) Any malfunction or clogged nozzle detected as a result of the
weekly examination or functional tests will be corrected immediately;
and (C) the procedure used to perform the functional test will be
posted at or near each belt drive which utilizes a deluge-type water
spray fire suppression system. The petitioner asserts that the proposed
alternative method will provide a measure of protection equal to or
greater than that of the standard.
Docket Number: M-2009-060-C.
Petitioner: Brooks Run Mining Company, LLC, 25 Little Birch Road,
Sutton, West Virginia 26601.
Mine: Poplar Ridge Deep Mine, MSHA I.D. No. 46-08885 and Saylor A
Mine, MSHA I.D. No. 46-09126, located in Webster County, West Virginia.
Regulation Affected: 30 CFR 75.1101-1(b) (Deluge-type water spray
systems).
Modification Request: The petitioner requests a modification of the
existing standard to permit an alternative method of compliance in lieu
of using blow-off dust covers for nozzles of a deluge-type water spray
system. The petitioner proposes to continue its weekly inspection and
functional tests for the complete deluge type water spray system. The
petitioner states that: (1) Weekly inspection and functional tests are
conducted of its complete deluge-type water spray system; (2) in view
of the frequent inspections and functional tests of the system, the
dust covers are not necessary because the nozzles can be maintained in
a unclogged condition through weekly use; and (3) it is burdensome and
exposes persons to undue hazards of falling from heights to recap the
large number of covers weekly after each inspection and functional
test. The petitioner asserts that the alternative method will at all
times guarantee no less than the same measure of protection afforded
the miners employed by said standard.
Docket Number: M-2009-061-C.
Petitioner: Owlco Energy, LLC, P.O. Box 976, Middlesboro, Kentucky
40965.
Mine: Mine No. 1, MSHA I.D. No. 15-18870, located in Letcher
County, Kentucky.
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 maximum length of trailing cables
supplying power to permissible pumps to be increased. The petitioner
states that: (1) This petition will apply only to trailing cables
supplying single phase, 240-volt power for permissible pumps; (2) the
maximum length of 240-volt power for permissible pumps will be 3,000
feet; (3) the 240-volt power for permissible pump trailing cables will
be no smaller than 10 American Wire Gauge (AWG); (4) the
company currently utilizes a P-20CE, 2G-3018 MSHA approved pump. This
pump is approved with 500 feet of 14/5 AWG trailing cable with
a circuit breaker set at 50 amps. Owlco Energy, LLC proposes the
alternative that will provide no less than the same protection by
protecting this circuit with a 30 amp circuit breaker. The petitioner
estimates that this setting would be satisfactory and be approximately
70-75 percent of the available fault current; (5) the outside diameter
(OD) of the 10/3 AWG cable is within 0.01 inch(s) of the
originally approved 14/5 AWG cable in the permissible XP
enclosure (XP-2181); (6) the mines current pump circuits exceeding the
approved lengths of trailing cables are attached with their respective
locations in the mine; (7) all future pump installations with trailing
cables installed that are longer than the approved lengths will be
maintained as shown in items 1-5. These pumps will be shown on the mine
electrical map and training will be provided to all mine employees
about his proper care and maintenance of these pumps; and (8) within
sixty (60) days after this petition is granted, the petitioner will
submit proposed revisions for their
[[Page 3255]]
approved Part 48 training plans to the District Manager for the area in
which the mine is located. The training will include the following: (a)
Training in mining methods and operating procedures that will protect
the cable against damage; (b) training in proper procedures for
examining the trailing cables to ensure the cables are in safe
operating condition; (c) training in hazards of setting the
instantaneous circuit breakers too high to adequately protect the
trailing cable(s); and (d) training in how to verify the circuit
interrupting device(s) protecting the trailing cable(s) are properly
set and maintained. The petitioner further states that 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 to all miners at Owlco Energy, LLC provided by
the existing standard.

and these circuit breakers will have permanent, legible labels. Each
label will identify the circuit breakers as being suitable for
protecting No. 2 AWG cables. The label will be maintained legible; (4)
replacement instantaneous trip units, used to protect No. 2 AWG
trailing cables, will be calibrated to trip at 700 amperes and this
setting will be sealed or locked; (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, persons designated by the mine operator
will visually examine the trailing cables to ensure that the cables are
in safe operating condition and that the instantaneous settings of the
specially calibrated breakers do not have seals or locks removed and
that they do not exceed the stipulated settings; (7) any trailing cable
that is not in safe operating condition will be removed from service
immediately and repaired or replaced; (8) each splice or repair in the

alternative method will not be implemented until designated miners have
been trained to examine the integrity of seals or locks, verify the
short-circuit settings, and properly examine trailing cables for
defects and damage; and (11) within 60 days after this petition is
granted, proposed revisions for their approved 30 CFR Part 48 training
plans will be submitted to the District Manager for the area in which
the mine is located. The training plan will include: (a) Training in
the mining methods and operating procedures for protecting the trailing
cables against damage; (b) training in proper procedures for examining
the trailing cables to ensure the cables are in safe operating
condition; (c) training in hazards of setting short-circuit
interrupting device(s) too high to adequately protect the trailing
cable(s); and (d) training in how to verify that the circuit
interrupting device(s) protecting the trailing cable(s) are properly
set and maintained. The petitioner further states that the procedures
of 30 CFR 48.3 for approval of proposed revisions to already approved
training plans will apply. The petitioner asserts that the alternative
method will at all times guarantee no less than the same measure of
protection afforded to all miners at the Century Mine as would be
provided by the existing standard.
