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. Consolidation Coal Company
[Docket No. M-94-87-C]
Consolidation Coal Company, 1800 Washington Road, Pittsburgh,
Pennsylvania 15241-1421 has filed a petition to modify the application
of 30 CFR 75.364(b)(2) (weekly examination) to its Blacksville No. 2
Mine (I.D. No. 46-01968) located in Monongalia County, West Virginia.
Due to deteriorating roof and rib conditions in certain areas of the
return air course, traveling the entire area would be unsafe. The
petitioner proposes to establish check points 1 and 2 to monitor the
methane and quantity of air in the affected area; to have a qualified
person conduct these tests weekly at each check point and record the
results in a book kept on the surface and made available for inspection
by interested persons; and to install a door in the overcast on the
mainline track haulage in order to observe the mine roof over the
overcast once a day to determine whether a roof fall and possible
collapse of the overcast exists. The petitioner asserts that the
proposed alternate method would provide at least the same measure of
protection as would the mandatory standard.
2. Drummond Company, Inc.
[Docket No. M-94-94-C]
Drummond Company, Inc., P.O. Box 10246, Birmingham, Alabama 35202
has filed a petition to modify the application of 30 CFR 75.800 (high-
voltage circuits; circuit breakers) to its Shoal Creek Mine (I.D. No.
01-02901) located in Jefferson County, Alabama. The petitioner requests
a modification of that portion of the standard that pertains to under-
voltage, grounded phase, overcurrent, and ground check opening the
circuit breaker. The petitioner proposes to use high-voltage contactors
with an electrical rating adequate for the connected load; to use
under-voltage, overload, grounded phase, and ground check protective
devices that would de-energize the high-voltage contactor; to use a
control circuit design for each high-voltage circuit that would
preclude automatic closing of the high-voltage contactor when there is
an under-voltage, overload, grounded phase, or ground check problem; to
use a control circuit design for each high-voltage contactor that would
preclude remote closing of the high-voltage contactor when there is an
overload, grounded phase, or ground check problem; and to use a short
circuit current that would trip the high-voltage circuit breaker, and a
control circuit design that would preclude automatic or remote closing
of the high-voltage circuit breaker. The petitioner asserts that the
proposed alternate method would provide at least the same measure of
protection as would the mandatory standard.
3. Drummond Company, Inc.
[Docket No. M-94-95-C]
Drummond Company, Inc., P.O. Box 10246, Birmingham, Alabama 35202
has filed a petition to modify the application of 30 CFR 75.803 (fail
safe ground check circuits on high-voltage resistance grounded systems)
to its Shoal Creek Mine (I.D. No. 01-02901) located in Jefferson
County, Alabama. The petitioner requests a modification of that portion
of the standard that pertains to under-voltage, grounded phase,
overcurrent, and ground check opening the circuit breaker. The
petitioner proposes to use high-voltage contactors with an electrical
rating adequate for the connected load; to use under-voltage, overload,
grounded phase, and ground check protective devices that would de-
energize the high-voltage contactor; to use a control circuit design
for each high-voltage circuit that would preclude automatic closing of
the high-voltage contactor when there is an under-voltage, overload,
grounded phase, or ground check problem; to use a control circuit
design for each high-voltage contactor that would preclude remote
closing of the high-voltage contactor when there is an overload,
grounded phase, or ground check problem; and to use a short circuit
current that would trip the high-voltage circuit breaker, and a control
circuit design that would preclude automatic or remote closing of the
high-voltage circuit breaker. The petitioner asserts that the proposed
alternate method would provide at least the same measure of protection
as would the mandatory standard.
4. Dynamic Recovery, Inc.
[Docket No. M-94-96-C]
Dynamic Recovery, Inc., P.O. Box 25, Clarksville, Pennsylvania
15322 has filed a petition to modify the application of 30 CFR 75.1103-
4(a) (automatic fire sensor and warning device systems; installation;
minimum requirements) to its Lazarus Mine (I.D. No. 36-08336) located
in Greene County, West Virginia. The petitioner proposes to install a
low-level carbon monoxide detection system as an early warning fire
detection system in all belt entries where a monitoring system would
identify a sensor location instead of in each belt flight. The
petitioner asserts that the proposed alternative method would provide
at least the same measure of protection as would the mandatory
standard.
5. Helvetia Coal Company
[Docket No. M-94-97-C]
Helvetia Coal Company, Box 729, Indiana, Pennsylvania 15701 has
filed a petition to modify the application of 30 CFR 75.1100-2(e)(2)
(quantity and location of fire fighting equipment) to its Lucerne No. 6
Extension (I.D. No. 36-07691) located in Indiana County, Pennsylvania.
The petitioner proposes to use two portable fire extinguishers, or one
portable fire extinguisher with twice the required capacity, at each
temporary electrical installation instead of using one fire
extinguisher and rock dust at such installations. The petitioner
asserts that the proposed alternative method would provide at least the
same measure of protection as would the mandatory standard.
6. Keystone Coal Mining Corporation
[Docket No. M-94-98-C]
Keystone Coal Mining Corporation, P.O. Box 729, Indiana,
Pennsylvania 15701 has filed a petition to modify the application of 30
CFR 75.511 (low- medium- or high-voltage distribution circuits and
equipment; repair) to its Emilie No. 1 Mine (I.D. No. 36-00821) and its
Jane Mine (I.D. No. 36-00823) both located in Armstrong County,
Pennsylvania. The petitioner proposes to utilize non-qualified persons
for changing fuses in DC pump fused disconnect boxes and fused trolley
wire taps. The petitioner states that the non-qualified persons would
be briefed and trained to ensure safe and proper conduct in performing
fuse changes. The petitioner asserts that the proposed alternative
method would provide at least the same measure of protection as would
the mandatory standard.
7. Keystone Coal Mining Corporation
[Docket No. M-94-99-C]
Keystone Coal Mining Corporation, P.O. Box 729, Indiana,
Pennsylvania 15701 has filed a petition to modify the application of 30

56.6309(b) (fuel oil requirements for ANFO) to its McCoy/Cove Mine
(I.D. No. 26-01925) located in Lander County, Nevada. The petitioner
proposes to blend recycled, used petroleum-based oil from equipment
operating at its mine with diesel fuel to create a blasting agent. The
petitioner asserts that this oil would not contain any hazardous
material listed in 40 CFR 261 and that the proposed alternate method
would provide at least the same measure of protection as would the
mandatory standard.
10. Independent Aggregates
[Docket No. M-94-35-M]
Independent Aggregates, P.O. Box 519, Inglis, Florida 34449 has
filed a petition to modify the application of 30 CFR 56.7055
(intersecting holes) to its I.A.C. Mine (I.D. No. 08-01035) located in
Citrus County, Florida. The petitioner propose to load each hole as
soon as it has been drilled, then move to the next hole, continue until
the end of the shift, and then continue loading on subsequent shifts
until the pattern is completed. Then, the round would be wired and shot
as soon as possible. The petitioner states that returning to the
collapsed holes to redrill would cause hazardous conditions. In
addition, the petitioner states that the proposed alternate method
would prevent a diminution of safety.
