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 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-2017-018-C.
    Petitioner: Revelation Energy, LLC, P.O. Box 249, Stanville, 
Kentucky 41659.
    Mine: D-1A Garmeada Mine, MSHA I.D. No. 15-19791, located in Bell 
County, Kentucky.
    Regulation Affected: 30 CFR 75.364(b)(2) (Weekly examination).
    Modification Request: The petitioner requests a modification of the 
existing standard in reference to weekly examinations in its entirety 
for the hazardous condition of return air course. The petitioner states 
that:
    (1) As a result of a dip with a steep incline on the end, a large 
pool of water has developed at the outby end of the Northwest Mains and 
extending inby approximately 1200 feet in the right-side return, in the 
No. 5 entry. This mine utilizes split air and there are two returns. 
There is a return entry in the No. 1 entry also. Currently, a 10-horse-
power pump with a 2-inch discharge line is installed in the pool of 
water. This is a low spot in the mine with elevations rising going in 
each direction. The mine height in this area is approximately 12 feet. 
The water level is currently 4\1/2\ feet deep. The water has been 
pumped down to current levels, reducing the affected area to 
approximately 70 feet in length. It is proposed to utilize a metal 
catwalk bridge, with handrails to provide safe travel through this area 
for the weekly examinations. The bridge would provide safer travel 
through the area, as the bridge is level. If the water is completely 
pumped out, it would result in a steep, slippery slope that would be 
treacherous to travel and could contribute to slip, trip, and fall 
hazards. It would be difficult to establish and maintain safe travel in 
this portion of the right return, No. 5 entry.
    (2) The remaining life of the reserve is approximately 10 years. 
Access to this reserve is only possible through the existing mine 
drifts, as all other approaches are blocked by abandoned mines. The 
procedures listed in this petition will provide a level of safety no 
less than equivalent to that afforded by 30 CFR 75.364(b)(2) for the 
remaining life of the mine.
    (3) Therefore, the petitioner proposes an alternate plan to provide 
safe access over pooled water in the right return, No. 5 entry for 
approximately 70 feet at the outby end of the Northwest Mains. The 
petitioner states that use of the bridge as described below will keep 
employees from being exposed to hazardous travel in order to meet the 
requirements of the applicable standard:
    (a) A metal catwalk bridge approximately 75 feet long with 
handrails will be utilized to provide safe access for travel across a 
pool of water.
    (b) Each end of the bridge across the entry will be blocked with 
danger signs, flagging, and/or fencing to warn miners of the potential 
hazard and that travel through this area is only permitted across the 
bridge.
    (c) A pump will be maintained in the pool to maintain the water 
level.
    (d) Life vests will be provided and worn while traveling across the 
bridge.
    (e) All miners at the D-1A Garmeada mine will be given notice of 
this request for modification during safety meetings.
    Within 60 days after approval of this petition and the order 
becoming final, the petitioner will submit proposed revisions to the 
Part 48 training plan to the District Manager. These revisions will 
apply to initial and refresher training.
    The petitioner asserts that the proposed alternative method will at 
all times guarantee no less than the same measure of protection 
afforded by the existing standard.

    Docket Number: M-2017-019-C.
    Petitioner: Marfork Coal Company, Inc., 500 Lee Street, East, Suite 
701 (25301), Post Office Box 2548, Charleston, WV 25329.
    Mine: Slip Ridge Cedar Grove Mine, MSHA I.D. No. 46-09048, located 
in Raleigh County, West Virginia.
    Regulation Affected: 30 CFR 75.360 (Preshift examination at fixed 
intervals).
    Modification Request: The petitioner requests a modification of the 
existing standard as it pertains to preshift examinations that are only 
required on a side of the mine that is active (i.e. both sides of the 
mine only have to be fully examined when both sides are active). The 
petitioner states that:
    (1) The Slip Ridge mine is a large underground coal mine that has 
been permanently divided into three separate areas via the installation 
of MSHA-approved 120 PSI mine seals.
    (2) On the East end of the mine is the Ellis Creek Side and this is 
the active mining side with two continuous miner sections producing 5 
to 6 days a week.
    (3) The West end of the mine is called the Slip Ridge Transfer and 
this end of the mine serves only as a belt through (i.e. transfer) for 
coal from two other Marfork mines (Horse Creek and Allen Powellton) on 
its way to the Marfork Plant.
    (4) The East and West ends of the mine are separated by 
approximately 3.66 miles of old mine works that were sealed on each end 
with MSHA-approved 120 PSI seals.
    (5) The East and West ends of the mine are ventilated by separate 
mine fans.

[[Page 49685]]

    (6) The East and West ends of the mine are monitored by separate CO 
systems.
    (7) The East and West ends of the mine have their own dispatcher.
    (8) Other than being on the opposite ends of a common sealed area, 
the East and West ends of the mine are effectively separate and 
independent underground coal mines.
    (9) Currently, if the East side of the mine is scheduled to produce 
coal, the regulations require preshift examinations in accordance with 
30 CFR 75.360 be completed on both sides of the mine, regardless of 
their autonomy.
    (10) Application of the existing standard may result in a 
diminution of safety to the miners as it currently requires that 
preshift examination on both the East and West ends of the mine be 
performed on any day that either end of the mine will be active (i.e. 
the West end has to be fully examined preshift every day that the East 
end wants to produce coal even if the West end is idle). Preshift 
examination of the idle side of the Slip Ridge Mine does not advance 
safety for the miners working on the active side of the mine and can 
expose examiners on the idle side to additional time and hazards 
underground.
    The petitioner proposes the following alternative method of 
compliance to the existing standard:
    (a) Since the East and West side are separated by two sets of 120 
PSI seals, ventilated with their own mine fans and monitored by 
independent CO systems, each end of the mine should be treated 
separately for purposes of 30 CFR 75.360.
    (b) On any active side of the Slip Ridge Mine, a preshift 
examination as set forth in 30 CFR 75.360 will be performed.
    (b) No preshift examination under 30 CFR 75.360 will be required on 
an idle side of the mine.
    (c) Preshift examinations of the idle side of the mine will be 
performed prior to work being performed underground on the previously 
idle side of the mine.
    (d) Marfork will update the CO monitoring systems to allow either 
side of the dispatcher to monitor the CO systems for both sides of the 
mine. This dual monitoring will allow the atmospheric conditions in the 
idle side of the mine to be monitored by the dispatcher on the active 
side of the mine.
    (e) If a CO event occurs that would otherwise require evacuation, 
both sides will withdraw personnel.
    (f) Marfork will set up dual monitoring of both mine fans so that 
the status of each fan can be monitored from both sides of the mine.
    (g) In the event of a fan stoppage on one side of the mine, both 
sides will withdraw personnel.
    (h) In the event of a fan stoppage on an idle side of the mine, the 
active side would be alerted via an alarm and personnel will be 
withdrawn from the active side.
    The petitioner asserts that the proposed alternative method will at 
all times guarantee no less than the same measure of protection 
afforded by the existing standard by ensuring that the examinations are 
performed on the active side of the mine while continually monitoring 
the fan and CO systems on the idle side of the mine.

    Docket Number: M-2017-020-C.
    Petitioner: Spartan Mining Company, 500 Lee Street, East, Suite 701 
(25301), Post Office Box 2548, Charleston, WV 25329.
    Mine: Road Fork #52 Mine, MSHA I.D. No. 46-09522, located in 
Wyoming County, West Virginia.
    Regulation Affected: 30 CFR 75.1700 (Oil and gas wells).
    Modification Request: The petitioner requests a modification of the 
existing standard in the following three situations: (1) When mining 
within 50 feet (+1-degree accuracy factor) of a horizontal wellbore; 
(2) when initially mining through a horizontal wellbore; and (3) when 
subsequently mining through horizontal wellbores as addressed in this 
petition. The petitioner states that:
    (1) Potential in-seam methane in the majority of the Road Fork #52 
Mine reserve area has been reduced and/or extracted by the drilling 
operation of horizontal coalbed methane wells by CDX Gas, LLC 
(``CDX''). The first well in the area was put into production in 
January 2006 and the last in October 2006. The location of these wells 
in relation to the future mining for the Road Fork #52 Mine is shown on 
the map attached to this petition as Exhibit A. (Road Fork #52 Mine 
will mine coal to the left of the mining shown on the map).
    (2) CDX will use the following methodology to drill these wells:
    (a) A vertical wellbore (access hole) is drilled and cased to a 
point 150 feet or more above the coal seal;
    (b) From the bottom of the casing in the access hole, a curved hole 
is drilled to intersect the coal seal at a tangent point;
    (c) From the tangent point, a short common horizontal bore is 
drilled horizontally through the coal seam for a distance up to 500 
feet;
    (d) From the end of the common horizontal bore, several 
interconnected horizontal bores, ranging from 5 to 6.5 inches in 
diameter are drilled horizontally through the coalbed for distances up 
to 3500 feet;
    (e) A second vertical wellbore (production hole) is drilled to 
intersect the common horizontal bore. The production hole is commonly 
cased with 7-inch O.D. casing to a point 100 feet more or less above 
the coal seam. The production hole is drilled 50 to 100 feet below the 
coal seam to provide a ``rat-hole'' for pumping liquid from the well; 
and
    (f) Coal bed methane gas entering the horizontal wellbores travels 
through the common horizontal bore to the production hole and then to 
the surface.
    (3) The Road Fork #52 Mine will employ the continuous mining room 
and pillar method of mining. It is anticipated that each lateral 
wellbore will be mined through at least once.
    (4) Prior to mining within 50 feet (+1-degree accuracy factor) of a 
horizontal wellbore, the petitioner proposes to verify that the 
following procedures have been performed on the well:
    (a) The well will be vented to outside atmosphere pressure for at 
least 8 hours;
    (b) A volume of fresh water sufficient to fill the horizontal 
(lateral) wellbores will be injected into the well with sufficient 
pressure to attain a bottomhole pressure of approximately 500 pounds 
per square inch (PSI);
    (c) The liquid will be bailed from the production hole, using 
normal bailing equipment, to a point just above the level of the coal 
seam;
    (d) A volume of gel, made up of 2 to 4 percent bentonite and fresh 
water, sufficient to fill the horizontal wellbores plus 25 percent 
excess, will be injected into the well with sufficient pressure to 
attain a bottomhole pressure of approximately 500 PSI; and
    (e) The wellbore will be filled to the surface with fresh water and 
allowed to stand for at least 72 hours, with the water level being 
supplemented as required. In the alternative, water will be injected 
into the wellbore for 72 hours at an average rate of 2 gallons per 
minute or more.
    (5) Prior to mining through the first lateral wellbore of a 
horizontal coalbed methane well, the petitioner proposes to verify that 
the following procedures have been performed on the well:
    (a) The water will be bailed from the vertical section of the 
wellbore, as close to the coal seam elevation as practical using normal 
bailing equipment;
    (b) The surface wellhead will be maintained open to bring the 
vertical

[[Page 49686]]

section of the wellbore to outside atmospheric pressure;
    (c) The petitioner further states that the MSHA District Manager 
and the appropriate West Virginia Office of Miners' Health Safety and 
Training representative will be notified at least 48 hours prior to the 
anticipated mine-through time;
    (d) Drivage sights will be installed within 80 feet of the mine-
through point;
    (e) Firefighting equipment will be provided near the working face, 
including two 10-pound fire extinguishers, 240 pounds of rock dust, and 
fire hose of sufficient length to reach the working face and capable of 
delivering at least 50 gallons per minute of water at minimum pressure 
of 50 PSI;
    (f) At least 9,000 CFM of intake air at the face will be supplied, 
but no less than the amount in the approved ventilation plan;
    (g) The continuous miner methane monitor will be calibrated prior 
to use when the mine-through is anticipated or is occurring;
    (h) A test for methane will be conducted with a hand-held methane 
detector at least every 10 minutes during the time mining commences at 
the minimum barrier distance line or within 30 feet of the wellbore, 
whichever is greater;
    (i) All equipment will be deenergized and the area thoroughly 
examined when the wellbore is intersected;
    (j) Once the area has been determined to be safe and mining has 
resumed, hand-held methane detector tests will continue at least every 
10 minutes during production shifts, until mining has progressed 20 
feet past the initial mine-through point;
    (k) No persons will be permitted in the area of the mine-through 
operation except those persons actually engaged in the operation, 
including mine management, personnel from MSHA, and personnel from the 
appropriate State agency; and
    (l) A certified official will directly supervise the mine-through 
operation and only the certified official in charge will issue 
instructions concerning the mine-through operation.
    (6) Prior to mining through a lateral wellbore of a coalbed methane 
well which has already at least one lateral wellbore mined through, the 
petitioner proposes to verify the following procedures have been 
performed on the well:
    (a) The water will be bailed from the vertical section of the 
wellbore, as close to the coal seam elevation as practical using normal 
bailing equipment;
    (b) The surface well head will be maintained open to bring the 
vertical section of the wellbore to outside atmospheric pressure;
    (c) Drivage sights will be installed within 80 feet of the mine-
through point;
    (d) Firefighting equipment will be provided near the working face, 
including two 10-pound fire extinguishers, 240 pounds of rock dust, and 
fire hose of sufficient length to reach the working face and capable of 
delivering at least 50 gallons per minute of water at minimum pressure 
of 50 PSI;
    (e) At least 9,000 CFM of intake air at the face will be supplied, 
but no less than the amount in the approved ventilation plan;
    (f) The continuous miner methane monitor will be calibrated on one 
of the five production shifts prior to the shift during which the mine-
through is anticipated;
    (g) A test for methane will be provided with a hand-held methane 
detector at least every 10 minutes during the time mining is conducted 
within 30 feet of the wellbore;
    (h) All equipment will be deenergized and the area thoroughly 
examined when the wellbore is intersected;
    (i) Once the area has been determined to be safe and mining has 
resumed, hand-held methane detector tests will continue at lease every 
10 minutes during production shifts, until mining has progressed 20 
feet past the initial mine-through point;
    (j) No persons will be permitted in the area of the mine-through 
operation except those persons actually engaged in the operation, 
including mine management, personnel from MSHA, and personnel from the 
appropriate State agency;
    (k) A certified official will directly supervise the mine-through 
operation and only the certified official in charge will issue 
instructions concerning the mine-through operation; and
    (l) The production hole will remain open and accessible until all 
mining susceptible of intersecting horizontal wellbores has been 
completed.
    The petitioner asserts that the proposed alternative method will at 
all times guarantee no less than the same measure of protection 
afforded by the existing standard.
