SUPPLEMENTARY INFORMATION: Section 101(c) of the Federal Mine Safety
and Health Act of 1977 and Title 30 of the Code of Federal Regulations
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 (Secretary)
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, the regulations at 30 CFR 44.10 and 44.11 establish
the requirements for filing petitions for modification.
II. Petitions for Modification
Docket Number: M-2019-054-C.
Petitioner: Castle Valley Mining LLC, P.O. Box 475, Huntington, UT
84528.
Mines: Castle Valley Mine #3, MSHA I.D. No. 42-02263 and Castle
Valley Mine #4, MSHA I.D. No. 42-02335, located in Emery County, UT.
Regulation Affected: 75.1909(b)(6) (Nonpermissible diesel-powered
equipment; design and performance requirements).
Modification Request: The petitioner requests a modification of the
existing standard to allow use of a Getman Corporation, Getman RDG
1504-C Diesel Roadbuilder, Serial No. 6579, a four- wheel-drive, low-
profile unit equipped with a grader blade that can be outfitted for
underground mining operations, as it was originally designed without
front brakes.
The petitioner states that:
(1) The petitioner utilizes a Getman Corporation, Getman RDG 1504-C
Diesel Roadbuilder at the Castle Valley No. 3 and Castle Valley No. 4
mines. The Getman Roadbuilder was manufactured without front wheel
brakes.
(2) The petitioner states that it is not feasible to install front
wheel brakes on the Getman Roadbuilder.
As an alternative to the existing standard, the petitioner proposes
the following:
(a) The petitioner will limit the maximum speed of the Getman
Roadbuilder to 10 miles per hour (MPH) by permanently blocking out any
gear that would provide a higher speed than 10 MPH. This would limit
the vehicle speed in both forward and reverse to a maximum of 10 MPH.
(b) The petitioner will train the grade operator to drop the grader
blade in the event that the brakes fail.
(c) The petitioner asserts that the proposed alternative method of
limiting the Getman Roadbuilder's speed to 10 MPH and training the
grade operator guarantees no less than the same measure of protection
afforded by the existing standard under 30 CFR 75.1909(b)(6).
Docket Number: M-2019-055-C.
Petitioner: INMET Mining, LLC, 144 E Market Place Blvd., Knoxville,
TN 37922.
Mine: D-31 Cut Through, MSHA I.D. No. 44-06782, located in Lee
County, Virginia.
Regulation Affected: 30 CFR 75.1108(c) (Approved conveyor belts).
Modification Request: The petitioner requests a modification of the
existing 30 CFR 75.1108(c) standard as applied to the conveyor belt
that travels through the D-31 Cut Through Mine connecting the
operator's Kentucky Mining Operations to the Preparation Plant located
at St. Charles, VA. The petitioner submits that a modification of the
Part 14 belt standard is warranted because the existing safety measures
that the petitioner has in place will make the conveyor belt in the D-
31 Cut Through Mine as safe as is required by Part 14.
The petitioner states that:
(1) The D-31 Cut Through Mine was developed in the late 1990's in
order to create a belt conveyor corridor from the operator's Kentucky
Mining Operations to the P-14 Preparation Plant at St. Charles, VA
(MSHA ID No. 44-05898). The belt conveyor corridor through the mountain
ridge was created to avoid the trucking of raw coal and rock products
through a dangerous, narrow road to get to the P-14 Preparation Plant.
The D-31 Cut Through Mine transports coal, via the conveyor belt, from
D28 Huff Creek Mine (MSHA ID No. 15-17234), the D29 Darby Fork Mine
(MSHA ID No. 15-02263), and D30 Clover Fork Mine (MSHA ID No. 15-
18647). The underground mines belt the coal to the Central Surface
Stockpile area, where it is fed onto the conveyor belt and transported
to the P-14 Preparation Plant.
(2) The D-31 Cut Through Mine is approximately 9,300 feet in depth
or length. It has approximately 1,200 feet of maximum cover at the
center of the ridge and it has 600 feet of cover overall. The mine has
two surface portals, one at either side of the ridge, and an immediate
escape-way in either direction from underground.
(3) Once the main line was advanced through the mountain ridge,
underground mining activities were halted and the equipment was
removed. In 2003, the mine became Active Non-Producing Status and a
steel cable belting conveyor was installed to go from the Day's Creek
Stockpile Area to the P-14 Preparation Plant.
(4) The conveyor belt is a continuous belt system, without any
underground
[[Page 64108]]
transfer points, head drives, or major infrastructure other than the
belt system itself. The tail piece of the belting conveyor is outside
of the mine on the Day's Creek Stockpile Area side and the Head Drive
is outside of the mine on the P-14 Preparation Plant side.
(5) The mine ventilation is purely intake air from all four-five
headings. The ventilation system intakes from the Day's Creek Stockpile
Area side to the main mine fan, which is located on the P-14
Preparation Plant side. There are no worked out, sealed, gob, or face
areas in the mine, allowing for air intake throughout.
The petitioner proposes the following alternative method:
(a) Due to the existing fire safety features within the D-31 Cut
Through belting corridor, the operator is petitioning for the continued
use of the existing steel cable conveyor belt in the D-31 Cut Through
Mine.
(b) The only underground electrical power sources in the mine are
low voltages and used to operate underground mine phones, belt
monitoring equipment, employee tracking, and communication equipment.
(c) There are no underground belt drives, take-up units or transfer
points, reducing the potential for frictional heat sources in the mine.
(d) The belt conveyor, which has been in operation since 2003, is
one continuous length (19,500 lineal feet), using vulcanized splices,
reducing the heat potential.
(e) The mine has a three-inch water line running parallel to the
entire length of the belt conveyor along with fire valves every 300
feet along the belt conveyor.
(f) Fire-fighting equipment is accessible at both the surface
portals and in the underground mine. In addition, an underground fire-
fighting hose is stored along the belt conveyor and it can reach the
entirety of the belt conveyor from the fire valves.
(g) The main travelway of the D-31 Cut Through Mine is adjacent to
the belt conveyor, so that the examination of the entire belt conveyor
is possible each time the travelway is examined.
(h) A certified foreman examines the conveyor belt each shift it is
in operation. All hazardous conditions are recorded in an examination
book that is kept at the surface. Hazardous conditions are corrected
according to 30 CFR.
(i) The Certified Foreman(s) making the examinations are equipped
with gas detection equipment to monitor the mine atmosphere for
potential harmful gases and or potential fires.
(j) The Certified Foreman(s) are equipped with heat detection
equipment to check the temperature of the belting conveyor and the
associated belt idlers to detect the possible increase of temperature
and replace belt idles early to reduce the heat and fire potential.
(k) The mine has CO monitors at 1,000 foot intervals along the belt
conveyor that are continuously checked from a central location.
(l) There is no coal production, so there is no return air course.
All entries are intake air. The belt air velocity is typically greater
than 100 feet per minute. CO monitors along the belt conveyor alert the
command center when CO levels reach 8PPM above ambient. If CO levels
are above 13PPM, an alarm is sounded.
(m) The D-31 Cut Through Mine does not have a history of Methane
gas.
(n) The mine is open at both ends, so that if the mechanical
ventilation fan stops due to mechanical issues, natural ventilation
will still occur.
(o) The mine has portals at both ends of the mine and employees
have additional escape-ways if there is an emergency.
(p) The Certified Foreman and other employees are tracked
throughout the mine and their locations are monitored. These
individuals communicate through hand held radios, underground mine
phones, and a dial up telephone that is located midway through the
underground mine.
(q) Each end of the belt has turnovers so that no belt rollers come
in contact with the coal carrying dirty side of the belt. This lowers
fire risks, since combustible material does not come in contact with
the belt during belt turnovers.
(r) Since the underground mine does not have belt drives, transfer
points or take up units, combustible materials including grease and oil
are not used.
(s) The state of Kentucky and the state of Virginia have committed
emergency mine rescue teams within one hour from the mine in the event
of an emergency.
(t) Unless there is additional work required, miner exposure to the
D-31 Cut Through Mine is minimal and limited to: Inspection by the
Certified Foreman; occasional clean up; and belt replacements.
(u) The underground floor and coal ribs are generally damp, which
reduces the possibility of a fire.
(v) Since being built in 2003, there have been no accidents related
to the belt conveyor or the D-31 Cut Through.
(w) The operator wishes to continue to use the existing belt in the
D-31 Cut Through until the end of its life, which is approximately 5
years. Once the current belt needs to be replaced, it will be done so
with Part 14 approved belting. The operator finds that if the purpose
of 75.1108(c) is to reduce the potential for a fire, the current
safeguards meet such a fire safety standard.
Docket Number: M-2019-056-C.
Petitioner: Marfork Coal Company, LLC, P.O. Box 457, Whitesville,
WV 25209.
Mine: Markfork Processing, MSHA I.D. No. 46-08374, located in
Raleigh County, West Virginia.
Regulation Affected: 30 CFR 77.214(a) (Refuse piles; general).
Modification Request: The petitioner requests a modification of the
existing 30 CFR 77.214(a) standard as applied to refuse piles. The
petitioner is requesting this modification in order to backfill six
abandoned mine openings with coal refuse as an alternative to 30 CFR
77.214(a), which does not allow locating refuse piles over abandoned
mine openings.
The petitioner states that:
(6) The six mine openings to be backfilled are located in the
Winifrede seam, which has an elevation of between 2000' and 2030'. The
six mine openings were formerly associated with the abandoned Dorothy
Mine that was operated by C&O Railway Fuel Mine Operations.
(7) Two of the six mine openings have not been sealed while the
other four are sealed with dirt. There are no pipes currently installed
at any of the entries.
(8) The mine dips to the northwest. Five of the six entries are on
the down-dip side of the mine while the last entry is north of the
hollow. Water from the six openings currently flows into an already
existing diversion ditch. There is no evidence that water is regularly
discharged from any of the openings.
The petitioner proposes the following alternative method:
(a) The six openings of the mine will be covered using coal refuse
as the construction material. All six openings will be back-stowed to a
length of 25 feet, as is required by 30 CFR 75.1711-2, using soil and
rock or flowable fill material such as JennChem Tek Seals or an
equivalent.
(b) The petitioner will build an underdrain system consisting of
durable rock cobbles and a perforated pipe, wrapped in filter fabric.
It will be installed at the base of the highwall along all six of the
mine openings.
(c) Two drains will be installed, one for the five entries on the
down-dip side of the mine and a second for the entry north of the
hollow. Each of the mine
[[Page 64109]]
entry pipes for the five entries on the down-dip side of the mine will
be connected and piped to the underdrain pipe.
(d) The mine entry pipes will be extended by a minimum of 40 feet
inby the opening and located along the rib in order to minimize
potential damage to the pipes during the backfill process. The
underdrain and mine drain will be extended to release into a perimeter
ditch located at the refuse facility.
(e) The mine openings and exposed coal seam will be covered with at
least four feet ofnon-combustible, non-refuse material including soil
and rock.
(f) In the event that water accumulates near sealed openings, an
internal drainage system will be constructed to provide a controlled
outlet to mitigate any potential combustion.
(g) The backfill zone isolates mine workings and the coal seam from
the proposed coal refuse fill, minimizing the potential for fire to
spread from the mine to the refuse fill.
(h) The coal refuse will be located in a maximum of two-foot lifts,
reducing the possibility of spontaneous combustion.
(i) The proposed backfill plan limits the potential for combustion
of the refuse or coal seam, which fulfills the intent of 30 CFR
77.214(a). The petitioner states that the proposed alternative provides
an equivalent or greater method of protection than is required by 30
CFR 77.214(a).
Docket Number: M-2019-007-M.
Petitioner: Genesis Alkali, LLC, P.O. Box 872, 580 Westvaco Rd.,
Green River, WY 82935.
Mine: Genesis Alkali @WESTVACO, MSHA I.D. No. 48-00152, located in
Sweetwater County, WY.
Regulation Affected: 30 CFR 57.22305 (Approved equipment (III
mines)).
Modification Request: The petitioner requests a modification of the
existing 30 CFR 57.22305 standard to permit an alternative, non-MSHA
approved Powered Air Purifying Respirator (PAPR). The petitioner
requests a modification of the existing standard to permit an
alternative method that will provide the same measure of protection as
the standard requires. The alternative PAPR is the 3M Versaflo TR-800
Intrinsically Safe Powered Air Purifying Respirator.
The petitioner states that:
(1) The petitioner's mine, Genesis Alkali @ Westvaco, is an
underground, Class III trona mine. The petitioner has historically
provided miners who wish to voluntarily wear respirators with 3M
Airstream Headgear-Mounted PAPRs. These respirators are MSHA approved
but they will be discontinued in 2020, according to the manufacturer.
(2) The proposed modification seeks relief from the application of
30 CFR 57.22305, and requests the use of a non-MSHA approved,
intrinsically safe, PAPR for the purpose of providing respiratory
protection and fresh air flow for miners who are potentially exposed to
nuisance dust. Such non-approved equipment would be used among miners
working under normal mining conditions in or beyond the last open
crosscut and where methane may enter the air current.
(3) The petitioner notes that the National Institute for
Occupational Safety and Health essentially states that the TR-800 was
tested to standards that should be considered equivalent to the MSHA
ACRI2001 criteria.
The petitioner proposes the following:
Miners who wish to use PAPRs will use the 3M Versaflo TR-800
Intrinsically Safe Powered Air Purifying Respirator (``TR-800''). While
it is not approved by MSHA, under 30 CFR parts 18 through 36, the TR-
800 has been extensively tested and approved as intrinsically safe
under the testing standards of Underwriters Laboratory (UL, which
operates in the United States and Canada), the American National
Standards Institute (ANSI), and the International Electrotechnical
Commission (IEC). Thus, the petitioner believes that the proposed
alternative method of using the TR-800 will at all times guarantee no
less than the same measure of protection afforded by the MSHA standard.
