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. H & S Coal Company
[Docket No. M-95-67-C]
H & S Coal Company, 534 Melrose Street, Marion Heights,
Pennsylvania 17832 has filed a petition to modify the application of 30
CFR 75.1400 (hoisting equipment; general) to its No. 1 Slope (I.D. No.
36-08447) located in Northumberland County, Pennsylvania. The
petitioner proposes to use a slope conveyance (gunboat) in transporting
persons without installing safety catches or other no less effective
devices but instead use a increased 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.
2. C. H. & S. Coal Company
[Docket No. M-95-68-C]
C. H. & S. Coal Company, Inc., P.O. Box 159, Birchleaf, Virginia
24220 has filed a petition to modify the application of 30 CFR 75.1711-
2 (sealing of slope or drift openings) to its Mine No. 3 (I.D. No. 44-
01246) located in Scott County, Virginia. The petitioner proposes to
install bat gates on openings at Mine No. 3 and Portals C in addition
to the two bat gates already installed by the Virginia Department of
Mines, Minerals and Energy at openings Portal A and Portal B in 1987.
The petitioner states that the U.S. Forest Service has information that
would verify that bat-friendly angle-iron gates have proven highly
successful in ensuring both human and bat safety throughout the
country; and that they would be willing to provide gate plans for
review and to take responsibility for the maintenance and upkeep of the
gates including responsibility for the public's safety. The petitioner
asserts that the proposed alternative method would provide at least the
same measure of protection as would the mandatory standard.
3. Bear Coal Company
[Docket No. M-95-69-C]
Bear Coal Company, P.O. Box 518, Somerset, Colorado 81434 has filed
a petition to modify the application of 30 CFR 75.364(b)(4) (weekly
examination) to its Bear No. 3 Mine (I.D. No. 05-03787) located in
Gunnison County, Colorado. Due to a roof fall in the ``C'' seam at
crosscuts #25 and #26, entries #0 and #1 impeding travel to two (2)
permanent seals the area cannot be traveled safely. The petitioner
proposes to establish monitoring stations to measure the quantity and
quality of air entering and leaving the affected area; to have a
certified person examine the stations on a daily basis and record the
results in a book kept on the surface and made available for inspection
by interested persons. The petitioner asserts that the proposed
alternative method would provide at least the same measure of
protection as would the mandatory standard.
4. Clinchfield Coal Company
[Docket No. M-95-70-C]
Clinchfield Coal Company, 1600 Laidley Tower, P.O. Box 553,
Charleston, West Virginia 25322 has filed a petition to modify the
application of 30 CFR 75.350 (air courses and belt haulage entries) to
its McClure No. 2 Mine (I.D. No. 44-04946) located in Dickenson County,
Virginia. Due to extreme restrictions on the intake airways, the
petitioner proposes to install a low-level carbon monoxide monitoring
system as an early warning fire detection system in all belt entries
used as intake air courses to ventilate the active working faces and to
dilute and render harmless respirable dust and harmful gases. The
petitioner states that application of the standard would result in
diminution of safety to the miners. The petitioner asserts that the
proposed alternative method would provide at least the same measure of
protection as would the mandatory standard.
5. Clinchfield Coal Company
[Docket No. M-95-71-C]
Clinchfield Coal Company, 1600 Laidley Tower, P.O. Box 553,
Charleston, West Virginia 25322 has filed a petition to modify the
application of 30 CFR 75.340(a) (underground electrical installations)
to its McClure No. 2 Mine (I.D. No. 44-04946) located in Dickenson
County, Virginia. Due to extreme air restrictions on the intake
airways, the petitioner proposes to install a low-level carbon monoxide
monitoring system in all belt entries used as intake air courses as an
early warning fire detection system to ventilate the active working
faces and to dilute and render harmless respirable dust and harmful
gases. The petitioner states that application of the standard would
result in a diminution of safety to the miners. The petitioner asserts
that the proposed alternative method would provide at least the same

6. Costain Coal, Inc.
[Docket No. M-95-72-C]
Costain Coal, Inc., P.O. Box 289, Sturgis, Kentucky 42459 has filed
a petition to modify the application of 30 CFR 75.1710-1 (canopies or
cabs; self- [[Page 29715]] propelled electric face equipment;
installation requirements) to its No. 9 Wheatcroft Mine (I.D. No. 15-
13920) located in Webster County, Kentucky. The petitioner requests a
modification of the mandatory standard to eliminate the use of a canopy
or cab on its Pettito Mule longwall shield puller. The petitioner
proposes to have its roof bolt spacing between the longwall shield
canopy tip and the coal block reduced from 5 foot to 4 foot centers; to
install additional roof bolts or cribs if adverse or questionable roof
conditions occur; to install additional roof bolts or cribs if the
longwall canopy tips are located more than 5 feet from the coal block;
and to have a certified person continue to evaluate the roof conditions
during longwall shield removal. The petitioner asserts that the
proposed alternative method would provide at least the same measure of
protection as would the mandatory standard.
7. Consolidation Coal Company
[Docket No. M-95-73-C]
Consolidation Coal Company, Consol Plaza, 1800 Washington Road,
Pittsburgh, Pennsylvania 15241 has filed a petition to modify the
application of 30 CFR 75.364(b) (weekly examination) to its Osage No. 3
Mine (I.D. No. 46-01455) located in Monongalia County, West Virginia.
Due to deteriorating roof and rib conditions in the Main West return
aircourse, between block markers 7 and 18, traveling the area would be
unsafe. The petitioner proposes to establish evaluation check points to
monitor the affected area; to have a certified person test for methane
and the quantity of air at each check point on a weekly basis, and
record the results in a record book kept on the surface and made
available for inspection by interested persons. The petitioner asserts
that the proposed alternative method would provide at least the same
measure of protection as would the mandatory standard.
8. Industrial Coal Corporation
[Docket No. M-95-74-C]
Industrial Coal Corporation, P.O. Box 1139, Grundy, Virginia 24614
has filed a petition to modify the application of 30 CFR 77.214(a)
(refuse piles; general) to its Mine No. 3 (I.D. No. 44-06673) located
in Buchanan County, Virginia. The petitioner proposes to seal the mine
by removing all sloughed overburden for 10 to 12 feet in front of and
to either side of the drift openings in order to allow placement of
suitable material for sealing. The petitioner proposes to install a
rock core underdrain constructed of durable sandstone rock, enclosed in
filter fabric to prevent piping, and/or 2 to 3 inch CMP drain for wet
seal in the lowest entry; to backfill the portal areas with an
impervious, noncombustible material that contains enough fines to
ensure an airtight seal and compacted to 90 percent Proctor dry
density; to backfill to 4 feet above drift openings or to 4 feet above
any visible cracks above the drifts; and to backfill all exposed coal
seams in the vicinity of the openings to a minimum depth of 4 feet
above the top of the seam. Petitioner states that all backfill material
would be placed in 2-foot lifts. The petitioner asserts that the
proposed alternative method would provide at least the same measure of
protection as would the mandatory standard.

located in Moffat County, Colorado. The petitioner requests that its
previous petition be amended to allow the addition of petroleum-based
solvent (NAPHTHA) to the recycled oil/diesel fuel mixture in the

agent at the minesite. The petitioner asserts that the proposed
alternative method would provide at least the same measure of
