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
[[Page 64623]]
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. 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-2014-031-C and M-2014-032-C.
Petitioner: Sunrise Coal LLC, 12661 Agricare Road, Oaktown, Indiana
47561.
Mines: Oaktown Fuels Mine No. 1, MSHA I.D. No. 12-02394, and
Oaktown Fuels Mine No. 2, MSHA I.D. No. 12-02418, both located in Knox
County, Indiana.
Regulation Affected: 30 CFR 75.1700 (Oil and gas wells).
Modification Request: The petitioner requests a modification of the
existing standard to mine through or near (whenever the safety barrier
diameter is reduced to a distance less than the District Manager (DM)
would approve pursuant to 30 CFR 75.1700) plugged oil or gas wells
penetrating the Indiana V coal seam.
a. The petitioner proposes to use the following procedures when
cleaning out and preparing oil and gas wells prior to plugging:
(1) A diligent effort will be made to clean the borehole to the
original total depth. If this depth cannot be reached, the borehole
will be cleaned out to a depth which would permit the placement of at
least 200 feet of expanding cement below the base of the lowest
mineable coal bed.
(2) When cleaning the borehole, a diligent effort will be made to
remove all the casing in the borehole. If it is not possible to remove
all of the casing, the casing that remains will be perforated or ripped
at intervals spaced close enough to permit expanding cement slurry to
infiltrate the annulus between the casing and the borehole wall at a
distance of at least 200 feet below the base of the lowest mineable
coal bed.
(3) If the cleaned-out borehole produces gas, a mechanical bridge
plug will be placed in the borehole in a competent stratum at least 200
feet below the base of the lowest mineable coal bed, but above the top
of the uppermost hydrocarbon-producing stratum. If it not possible to
set a mechanical bridge plug, a substantial brush plug may be used.
(4) A suit of logs will be made consisting of a caliper survey,
directional deviation survey, and log(s) suitable for determining the
top and bottom of the minable coal beds and potential hydrocarbon-
producing strata and the location for a bridge plug.
(5) Properly place mechanical bridge plugs or a suitable brush plug
to isolate the hydrocarbon-producing stratum from the expanding cement
plug, if the upper-most hydrocarbon-producing stratum is within 200
feet of the base of the lowest mineable coal bed. Nevertheless, place a
minimum of 200 feet of expanding cement below the lowest mineable coal
bed
(6) The wellbore will be completely filled and circulated with a
gel that inhibits any flow of gas, supports the walls of the borehole,
and increases the density of the expanding cement. This gel will be
pumped through open-end tubing run to a point approximately 20 feet
above the bottom of the cleaned out area of the borehole or bridge
plug.
b. The petitioner proposes to use the following procedures for
plugging oil or gas wells to the surface:
(1) A cement plug will be set in the wellbore by pumping an
expanding cement slurry down the tubing to displace the gel and fill
the borehole to the surface. (As an alternative, the cement slurry may
be pumped down the tubing so that the borehole is filled with Portland
cement or a Portland cement-fly ash mixture from a point approximately
100 feet above the top of the lowest minable coal bed to the surface
with an expanding cement plug extending from at least 200 feet below
the lowest minable coal bed to the bottom of the Portland cement).
There will be at least 200 feet of expanding cement below the base of
the lowest minable coal bed.
(2) A surface casing, small quantity of steel turning, or other
small magnetic particles will be embedded in the top of the expandable
cement near the surface to serve as a permanent magnetic monument of
the borehole. As an alternative, a steel rod may be driven into the
ground next to the borehole.
c. The petitioner proposes to use the following procedures for
plugging oil and gas wells using the vent pipe method:
(1) Run a 4\1/2\-inch or larger vent pipe into the wellbore to a
depth of 100 feet below the lowest minable coal bed and swedged to a
smaller diameter pipe, if desired, which will extend to a point
approximately 20 feet above the bottom of the cleaned out area of the
borehole or bridge plug.
(2) Set a cement plug in the wellbore by pumping an expanding
cement slurry, Portland cement, or a Portland cement-fly ash mixture
down the tubing to displace the gel so the borehole is filled with
cement. The borehole and the vent pipe will be filled with expanding
cement for a minimum of 200 feet below the base of the lowest minable
coal bed. The top of the expanding cement will extend upward to a point
approximately 100-feet above the top of the highest minable coal bed.
(3) Evacuate all fluid from the vent pipe to facilitate testing for
gasses. The expanding cement will not be disturbed during the
evacuation of fluid.
(4) Protect the vent pipe to prevent liquids or solids from
entering the wellbore but ready access will be permitted to the full
internal diameter of the vent pipe when necessary.
d. The petitioner proposes to use the following procedures for
plugging oil or gas wells for use of degasification boreholes:
(1) Set a cement plug in the wellbore by pumping an expanding
cement slurry down the tubing to displace the gel and provide at least
200 feet of expanding cement below the lowest minable coal bed. The top
of the expanding cement will extend upward to a point above the top of
the coal bed being mined. The distance will be based on the average
height of the roof strata breakage for the mine.
(2) To facilitate methane drainage, degasification casing of
suitable diameter, slotted or perforated throughout its lower 150 feet
to 200 feet will be set in the borehole to a point 10 feet to 30 feet
above the top of the expanding cement.
(3) Cement the annulus between the degasification casing and the
borehole wall from a point immediately above the slots or perforations
to the surface.
(4) Clean out the degasification casing for its total length.
(5) Fit the top of the degasification casing with a wellhead
equipped as required by the District Manager (DM). Such equipment may
include check valves, shut-in valves, sampling ports, flame arrestor
equipment, and security fencing.
e. The petitioner proposes to use the following procedures whenever
the safety barrier diameter is reduced to less than the DM would
approve pursuant to 30 CFR 75.1700 or proceeding with an intent to cut
through a plugged well:
(1) Notify the DM or designee prior to reducing the safety barrier
to a distance less than the DM would approve pursuant to 30 CFR 75.1700
or
[[Page 64624]]
proceeding with an intent to cut through a plugged well.
(2) The DM or designee may conduct a conference prior to mining
through any plugged well to review and approve the specific procedures
for mining through the well. Representatives of the operator,
representative of the miners, and the appropriate State agency will be
informed within a reasonable time prior to the conference to be given
opportunity to attend and participate. This meeting may be called by
the operator.
(3) Mining in close proximity to or through a plugged well will be
done on a shift approved by the DM or designee.
(4) Notify the DM or designee, representative of the miners, and
the appropriate State agency in sufficient time for them to have a
representative present prior to mining-through operation.
(5) Install drivage sights at the last open crosscut near the place
to be mined to ensure intersection of the well. The drivage sights will
not be more than 50 feet from the well.
(6) Firefighting equipment, including fire extinguishers, rock
dust, and sufficient fire hose to reach the working face area of the
mining-through will be available and operable during each well mine-
through. Locate the fire hose in the last open crosscut of the entry or
room. All fire hoses will be ready for operation during the mining-
through.
(7) Keep available at the last open crosscut a sufficient supply of
roof support and ventilation materials. In addition, keep emergency
plugs available in the immediate area of the mine-through.
(8) Maintain the quantity of air required by the approved mine
ventilation plan behind the line brattice and in the last open cross
cut during mining-through.
(9) Check equipment for permissibility and service it on the shift
prior to mining through the well and maintain the water line to the
section tail with a sufficient amount of fire hose to reach the
farthest point of penetration on the section.
(10) Calibrate the methane monitor on the continuous mining machine
prior to mining through the well.
(11) When mining is in progress, test methane levels with a hand-
held methane detector at least every 10 minutes from the time that the
continuous mining machine is within 30 feet of the well until the well
is intersected and immediately prior to mining-through. No individual
is allowed on the return side during the actual cutting process until
the mining-through has been completed and the area examined and
declared safe by a certified person.
(12) Keep the working place free from accumulations of coal dust
and coal spillages, and place rock dust on the roof, rib, and floor to
within 20 feet of the face when mining through the well on the shifts
during which the cut-through will occur.
(13) Deenergize all equipment when the wellbore is intersected and
thoroughly examine the place and determine it safe before resuming
mining. Any casing will be removed and no open flame is permitted in
the area until adequate ventilation has been established around the
wellbore.
(14) After a well has been intersected and the working place
determined safe, continue mining inby the well at a distance sufficient
to permit adequate ventilation around the area of the wellbore.
(15) No person will be permitted in the area of the mining-through
operation except those actually engaged in the mining operation,
company personnel, representative of the miners, personnel from MSHA,
and personnel from the appropriate State agency.
(16) A certified official will directly supervise the mining-
through operation and only the certified official in charge will issue
instructions concerning the mining-through operation.
(17) MSHA personnel may interrupt or halt the mining through
operation when it is necessary for the safety of the miners.
(18) The operator will file a plugged affidavit setting forth the
persons who participated in the work, a description of the plugged
work, and a certification by the operator that the well has been
plugged.
(19) Within 60 days after this petition becomes final, the
petitioner will submit proposed revisions for its approved part 48
training plan to the DM. The revisions will include initial and
refresher training regarding the compliance with the terms and
conditions of this petition for modification.
The petitioner asserts that the proposed alternative method will at
all times guarantee no less than the same measure or protection
afforded by the existing standard.
Docket Number: M-2014-033-C.
Petitioner: Emerald Processing, LLC, 1144 Market Street, Suite 400,
Wheeling, West Virginia 26003.
Mine: Peerless Rachel Mine, MSHA I.D. No. 46-09258, 4449 Left Fork
of Joe's Creek, Comfort, West Virginia 25049, located in Boone County,
West Virginia.
Regulation Affected: 30 CFR 75.1909(b)(6) (Nonpermissible diesel-
powered equipment design and performance requirements).
Modification Request: The petitioner requests a modification of the
existing standard to permit the use of the Getman Diesel Grader with
rear wheel brakes at the Peerless Rachel Mine. The petitioner states
that:
(1) The maximum speed of the diesel grader will be limited to 10
miles per hour by physically blocking the higher gear ratios that
provide for speeds exceeding 10 miles per hour.
(2) The miners that operate the grader will be trained to recognize
the gear blocking device and its proper application and requirements.
(3) The miners who operate the grader will be trained to drop the
grader blade to provide additional stopping capability in emergencies.
(4) The low speeds coupled with the availability of the grader
blade for stopping in emergencies will provide for the appropriate
stopping ability. The rear wheel brakes will be maintained in proper
working condition at all times.
(5) All other applicable requirements of the Federal Mine Safety
and Health Act of 1977 and its corresponding regulations for the Getman
grader will apply.
(6) This petition is limited to the Getman diesel grader, Serial
No. 6732.
(7) Within 60 days after this petition becomes final, the
petitioner will submit to the District Manager proposed revisions for
the approved part 48 training plan that will specify initial and
refresher training consistent with the terms and conditions stated in
this petition.
The petitioner asserts that the proposed alternative method will
guarantee no less than the same measure of protection to all miners as
would be provided by the existing standard.
Docket Number: M-2014-034-C.
Petitioner: Lone Mountain Processing, Inc., Drawer C, St. Charles,
Virginia 24282.
Mine: Clover Fork Mine, MSHA I.D. No. 15-18647, located in Harlan
County, Kentucky.
Regulation Affected: 30 CFR 75.310(a)(3) (Installation of main mine
fans).
Modification Request: The petitioner requests a modification of the
existing standard to permit the use of fan signal monitoring provided
by the Communication Center at Huff Creek Mine as an alternative to
having personnel on the surface at the mine to monitor fan operation.
In support of the request, the petitioner states that:
[[Page 64625]]
(1) The Clover Fork fan can be monitored for operation at the Huff
Creek Communication Center.
(2) Huff Creek Mine Communication Center personnel are present at
all times when miners are underground.
(3) If there is an interruption in the fan operation, a
notification from the Huff Creek Communication Center can be given to
the miners underground at Clover Fork mine.
(4) Fan alarm signal monitoring by the Huff Creek Mine
Communication Center is accomplished in two ways, first by fan signal
connection to mine phones, and by a fiber optic line that is running
from Clover Fork mine to the Huff Creek mine.
(5) The fiber optic line is connected to the CO monitoring and
tracking system computer at Clover Fork mine which receives an input
from the fan alarm signal device. The fiber optic line terminates at a
computer in the Communication Center and provides both audible and
visual notification if the Clover Fork fan stops operating.
(6) Voice communication to the Clover Fork mine is accomplished by
three separate connections and also by wireless tracking system radios.
Primary communication is by a mine phone line running through Huff
Creek mine along A-Main entries to the borehole connection between the
mines.
(7) Backup to the mine phone system is an overland copper pair for
the emergency phone system provided by the land line telephone company.
A third way of communication to the mine is by land line telephone to
the mine office. Tracking system radios provide a fourth means of
communication.
(8) In the event that the monitoring system for the fan should fail
at the Huff Creek Mine Communication Center, Clover Fork mine
management will provide personnel to monitor the fan operation at the
mine site until repairs are made to the Huff Creek Mine Communication
Center system.
The petitioner asserts that the proposed alternative method
provides the same level of protection to all miners as provided by the
existing standard.
