SUPPLEMENTARY INFORMATION: Section 101(c) of the Federal Mine Safety
and Health Act of 1977 and title 30 of the Code of Federal Regulations
(CFR) part 44 govern the application, processing, and disposition of
petitions for modification.
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. The application of such standard to such mine will result in a
diminution of safety to the miners in such mine.
In addition, Sec. Sec. 44.10 and 44.11 of 30 CFR establish the
requirements for filing petitions for modification.
II. Petition for Modification
Docket Number: M-2022-004-C.
Petitioner: Century Mining, LLC, 7004 Buckhannon Road, Volga, West
Virginia 26238.
Mine: Longview Mine, MSHA ID No. 46-09447, located in Barbour
County, West Virginia.
Regulation Affected: 30 CFR 18.35(a)(5)(i), Portable (trailing)
cables and cords.
Modification Request: The petitioner seeks modification of the
existing standard to permit 995-volt, 575-volt, and 480-volt trailing
cable lengths up to 1,000 feet providing power to section equipment
including continuous mining machine, roof bolters, shuttle cars, and
auxiliary fans during: Initial bottom development; mains, sub-mains,
and three-entry sections development; bleeder and recovery entries
development; and mining around gas wells.
The petitioner states that:
(a) The mine is currently under construction.
(b) The mine will utilize the room and pillar and longwall mining
methods to extract coal and will employ approximately 375 coal miners.
(c) A modification to the existing standard would enhance the
safety of the miners by minimizing the number of power center moves,
thereby reducing exposure to electrical hazards associated with cable
handling.
(d) Use of 1,000-foot cables would reduce the chance of a fire on a
working section by allowing power centers to be farther from the
working face.
The petitioner proposes the following alternative method:
(a) The maximum length of the 995-volt, 575-volt, and 480-volt
trailing cables will be 1,000 feet.
(b) The section equipment's trailing cables will not be smaller
than No. 6 American Wire Gauge (AWG). At no time will a trailing cable
be smaller than specified in the approval documentation for the
machine.
(c) All circuit breakers used to protect trailing cables exceeding
the maximum length specified in 30 CFR 18.35(a)(5)(i) will have
instantaneous trip units properly calibrated and adjusted to trip at no
more than the smallest of the following values:
(1) The setting specified in 30 CFR 75.601-1;
(2) the setting specified in the approval documentation for the
machine; or
[[Page 16234]]
(3) 70 percent of the minimum phase-to-phase short-circuit current
available at the end of the trailing cable.
(d) The calibrated trip setting of the circuit breakers will be
sealed, locked, or protected so that the setting cannot be changed.
(e) The circuit breakers will have permanent, legible labels
indicating the circuit, cable size, maximum cable length, and the
maximum instantaneous trip unit setting. If the trailing cable sizes
are intermixed at a section power center, the plugs will be constructed
or designed, for example, keyed or sized, to permit only the proper
type and length of cable to be plugged into the receptacle with the
proper settings.
(f) Replacement instantaneous trip units used to protect trailing
cables affected by this petition will be calibrated and set in
accordance with alternative method item (c). This setting will be
sealed, locked, or protected.
(g) All components providing short-circuit protection will have a
sufficient interruption rating in accordance with the maximum
calculated fault currents available.
(h) Any trailing cable not in safe operating condition will be
removed from service immediately and repaired or replaced.
(i) If the mining methods or operating procedures cause or
contribute to trailing cable damage, the cable will be removed from
service immediately and repaired or replaced. Additional precautions
will be taken to ensure that, in the future, the cable is protected and
maintained in safe operating condition.
(j) Each trailing cable splice or repair 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 will be vulcanized with flame resistant material or made with
material that has been approved by MSHA as flame resistant. Splices
will comply with the requirements of 30 CFR 75.603 and 75.604.
(k) At the beginning of each production shift, persons designated
by the mine operator will visually examine trailing cables to ensure
that they are in safe operating condition. The instantaneous trip unit
settings of the specially calibrated circuit breakers will also be
visually examined to ensure that the seals or locks have not been
removed and that they are set in accordance with alternative method
item (c).
(l) Permanent warning labels will be installed and maintained on
the cover(s) of the power center or distribution box identifying the
location of each sealed short-circuit protection device. The labels
will warn miners not to change or alter the sealed short-circuit
settings.
(m) This petition will apply to the initial bottom development of
the mine, working sections that mine around gas wells, and working
sections developing mains, submains, three entry panels, and bleeder
and recovery entries.
(n) This petition will not be implemented until miners designated
to examine the integrity of the seals or locks, to verify the short-
circuit settings, and to examine trailing cables for defects and damage
have received training.
(o) Within 60 days after the Proposed Decision and Order (PDO)
becomes final, the petitioner will submit proposed revisions for its
approved part 48 training plan to the District Manager. The proposed
revisions will include initial and refresher training regarding
compliance with the terms and conditions of the PDO.
The petitioner asserts that the alternative method proposed will at
all times guarantee no less than the same measure of protection
afforded the miners under the mandatory standard.

Acting Director, Office of Standards, Regulations, and Variances.
