Petitions for Modification
The following parties have filed petitions to modify the
application of mandatory safety standards under section 101(c) of the
Federal Mine Safety and Health Act of 1977.
1. Mallie Coal Company, Inc.
[Docket No. M-98-91-C]
Mallie Coal Company, Inc., Rt. 1 Box 173, Woodbine, Kentucky 40771
has filed a petition to modify the application of 30 CFR 75.380(f)(4)
(escapeways; bituminous and lignite mines) to its Mine No. 4 (I.D. No.
15-17603) located in Knox County, Kentucky. The petitioner proposes to
use one twenty or two ten pound portable chemical fire extinguishers on
each Mescher Jeep. If two fire extinguishers are used, one ten pound
extinguisher would be mounted in the operator's deck with the other
mounted
[[Page 2520]]
on the jeep for accessibility by the operator and if one fire
extinguisher is used, it would be mounted in the operator's deck. The
petitioner states that in either case, a total of twenty pounds of fire
extinguisher capability would be carried on each Mescher Jeep and
readily accessible to the jeep operator. The petitioner proposes to
have the equipment operator inspect each fire extinguisher daily prior
to entering the mine, maintain records of the inspections, and replace
defective fire extinguishers prior to entering the mine. The petitioner
asserts that the proposed alternative method would provide at least the
same measure of protection as would the mandatory standard.
2. M & M Anthracite Coal Company
[Docket No. M-98-99-C]
M & M Anthracite Coal Company, 245 Second Street, Joliett,
Pennsylvania 17981-1315 has filed a petition to modify the application
of 30 CFR 75.1400 (hoisting equipment; general) to its L.V. #3 Vein
Slope (I.D. No. 36-08744) located in Schuylkill County, Pennsylvania.
The petitioner proposes to use a slope conveyance (gunboat) in
transporting persons without installing safety catches or other not
less effective devices but instead use inceased rope strength/safety
factor and secondary safety rope connection in place of such devices.
The petitioner asserts that the proposed alternative method would
provide at least the same measure of protection as would the mandatory
standard.
3. Cyprus Plateau Mining Corporation
[Docket No. M-98-100-C]
Cyprus Plateau Mining Corporation, One Oxford Centre, 301 Grant
Street, 20th Floor, Pittsburgh, Pennsylvania 15219-1410 has filed a
petition to modify the application of 30 CFR 75.804(a) (underground
high-voltage cables) to its Willow Creek Mine (I.D. No. 42-02113)
located in Carbon County, Utah. The petitioner proposes to use
specially designed high-voltage cables on longwall equipment that would
comply with existing standard 30 CFR 75.804(a), or would use type
CABLE/BICC Anaconda brand 5KV, 3/C type SHD+GC; AmerCable Tiger Brand,
3/C, 5KV, type SHD-CGC; Pirelli 5KV, 3/C, type SHD-CENTER-GC; or
similar 5,000 volt cable with center ground check conductor,
manufactured to the ICEA Standard S-75-381 for type SHD, three-
conductor cables. The petitioner states that the cable would be MSHA
accepted as flame-resistant; that the ground check conductor would not
be smaller than a No. 16 AWG stranded conductor; that the cable
construction shall be symmetrical 3/C, 3/G, and 1/GC; that all
electrical personnel who perform maintenance on the longwall would
receive training in the installation, splicing and repair, and
permissibility requirements of these high-voltage cables; and that
proposed revisions for its part 48 training plan would be submitted to
the District Manager within 60 days after the proposed decision and
order becomes final. The petitioner asserts that the proposed
alternative method would provide at least the same measure of
protection as would the mandatory standard.
4. Cyprus Plateau Mining Corporation
[Docket No. M-98-101-C]
Cyprus Plateau Mining Corporation, One Oxford Centre, 301 Grant
Street, 20th Floor, Pittsburgh, Pennsylvania 15219-1410 has filed a
petition to modify the application of 30 CFR 75.1002 (location of
trolley wires, trolley feeder wires, high-voltage cables and
transformers) to its Willow Creek Mine (I.D. No. 42-02113) located in
Carbon County, Utah. The petitioner requests that the Proposed Decision
and Order (PDO) be amended for its previous Petition for Modification,
docket number M-95-167-C to use high-voltage longwall mining systems to
power permissible longwall equipment. The petitioner requests that the
PDO be amended to clarify the petition and to conform the requirements
of the PDO to the equipment being used. The petitioner requests changes
to Item No. 22 to provide information to the miners that adequate means
to secure the mid-face box and on-line connector has been installed to
provide secure connections to the high-voltage cables to allow the
petitioner the option of using either of these items; and to change
Item No. 24 to clarify that high-voltage personal equipment is needed
to handle energized high-voltage cables and provide information
concerning storage facility for protective equipment. The petitioner
requests that Items No. 34 and 35 be combined to provide information to
warn miners that the high-voltage controller contains capacitors that
must be discharged and grounded and that all circuits are not
deenergized, and to address caution labels for the power center,
controller, and shearer in one stipulation instead of two. The
petitioner requests a new Item No. 35 be added to include information
that would warn the miners of 4,160 volt cables on board the shearer
before opening any covers. The petitioner requests that Item No. 36(c)
be changed because at this time capacitors are not installed at the
power center; that Item 38 be changed because capacitors are installed
on the load side in the controller; that Item 39 be revised to add a
stipulation at the end of paragraph (d); and that Item 40 be changed to
facilitate locating grounded phase, or open conductors within the
cable. The petitioner asserts that the proposed alternative method
would provide at least the same measure of protection as would the
mandatory standard.
5. Cyprus Plateau Mining Corporation
[Docket No. M-98-102-C]
Cyprus Plateau Mining Corporation, One Oxford Centre, 301 Grant
Street, 20th Floor, Pittsburgh, Pennsylvania 15219-1410 has filed a
petition to modify the application of 30 CFR 75.350 (air courses and
belt haulage entries) to its Willow Creek Mine (I.D. No.42-02113)
located in Carbon County, Utah. The petitioner requests that its
previously granted petition, docket number M-95-166-C be amended to
allow the use of belt air to ventilate working sections with more than
two entries. The petitioner proposes to install a carbon monoxide
monitoring system in all belt entries utilized as intake air courses as
an early warning fire detection system. The petitioner asserts that the
proposed alternative method would provide at least the same measure of
protection as would the mandatory standard.
6. CONSOL of Kentucky, Inc.
[Docket No. M-98-103-C]
CONSOL of Kentucky, Inc., Consol Plaza, 1800 Washington Road,
Pittsburgh, Pennsylvania 15241-1421 has filed a petition to modify the
application of 30 CFR 75.701 (grounding metallic frames, casings, and
other enclosures of electric equipment) to its Big Springs #16 Mine
(I.D. No. 15-17957), its E3RF Mine (I.D. No. 15-17894), its Motts
Branch Mine (I.D. No. 15-18012), and its Big Springs No. 17 Mine (I.D.
No. 15-17996) all located in Knotts County, Kentucky; and its Wiley
(MC) Mine (I.D. No. 15-17220), its E3-MC Mine (I.D. No. 15-17720), and
its Loves Branch Mine (I.D. No. 15-17814) located in Letcher County,
Kentucky. The petitioner proposes to use a low and medium voltage,
three-phase, alternating current for use underground from a portable,
diesel-driven generator and to connect the neutral of the generator's
transformer secondary through a suitable resistor to the frame of the
diesel generator. The petitioner states that the frame of the diesel
[[Page 2521]]
generator would not have solid connection to a borehole casing, a metal
waterline, or a grounding conductor with a low resistance to earth;
that the resistor used to connect the neutral of the transformer
secondary to the frame of the diesel generator would be rated for
continuous duty and would limit the phase-to-frame fault current for
each of the low and medium voltage circuits to a maximum of 0.5
amperes; that each outgoing power circuit of the diesel generator would
be protected by a circuit breaker; that each outgoing power circuit of
the diesel generator would be equipped with a relay that would monitor
the phase-to-frame fault current and trip the appropriate circuit
breaker when the phase-to-frame fault current exceeds 0.1 amperes; that
the 995-volt circuits would be equipped with a sensitive ground fault
relay that would cause the respective circuit breaker(s) to trip and
shut down the diesel engine when a phase-to-frame fault of 90
milliamperes or higher occurs; that a 1/0 A.W.G. or larger external
ground conductor would be solidly connected between the frames of the
diesel generator and mining equipment being powered and between the
trailing cable coupler and the frame of equipment where the cable
coupler connects to the coupler of the equipment; that the cable power
from the generator to the equipment would be type SHD-GC on machines
greater that 660 volts and would have a minimum of 2,000 volt rating
and an outer jacket that has been MSHA approved as flame-resistant;
that strain relief would be provided on each end of the shielded cable
that extends between the generator and the piece of equipment being
powered; that prior to moving each piece of equipment and upon start-up
of the diesel generator, a functional test of the ground fault and
ground wire monitor systems would be performed and a record would be
maintained on the results of the tests; that all circuit breaker
settings would be adjusted to provide short-circuit protection; and
that prior to using the diesel generator system, ``hands on'' training
would be provided to all qualified persons on proper testing procedures
and incorporated into the part 48 training plans. The petitioner
asserts that the proposed alternative method would provide at least the
same measure of protection as would the mandatory standard.

U.S. Steel Mining Company, LLC, P.O. Box 338 Pineville, West
Virginia 24874 has filed a petition to modify the application of 30 CFR
75.1002 (location of trolley wires, trolley feeder wires, high-voltage
cables and transformers) to its No. 50 Mine (I.D. No. 46-01816) located
in Wyoming County, West Virginia. The petitioner proposes to use 4,160
volt cables to supply power to permissible longwall mining equipment.
The petitioner asserts that the proposed alternative method would
provide at least the same measure of protection as would the mandatory
standard.
8. Windsor Coal Company
[Docket No. M-98-105-C]
Windsor Coal Company, P.O. Box 39, West Liberty, West Virginia
26074 has filed a petition to modify the application of 30 CFR
75.364(b)(1) (weekly examination) to its Windsor Mine (I.D. No. 46-
01286) located in Brooke County, West Virginia. Due to deteriorating
roof and rib conditions in certain areas of the intake air course,
traveling the affected area would be unsafe. The petitioner proposes to
establish evaluation points to monitor the air and gas measurements in
the affected area; to maintain the evaluation points in safe
conditions; to have a certified person test for methane and the quality
and quantity of air at both evaluation points; and to have the person
making the examinations and test place their initials, date, and time
at the evaluation points and in a book on the surface made available
for interested persons. The petitioner asserts that the proposed
alternative method would provide at least the same measure of
protection as would the mandatory standard.
