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. Petition for Modification

    Docket Number: M-2019-057-C.
    Petitioner: Marfork Coal Company, LLC, P.O. Box 457, Whitesville, 
WV 25209.
    Mine: Black Eagle, MSHA I.D. No. 46-09550, located in Raleigh 
County, West Virginia.
    Regulation Affected: 30 CFR 75.1700 (Oil and gas wells).

[[Page 70570]]

    Modification Request: The petitioner requests a modification of the 
existing standard, 30 CFR 75.1700, as it relates to vertical oil and 
gas wells at the Black Eagle mine. The operator is petitioning in order 
to mine through existing wells as they are met.
    The petitioner states that:
    (1) The Black Eagle mine extracts coal from the Eagle coal seam. 
The Black Eagle mine operates one continuous miner section that 
produces coal 5 to 6 days per week.
    (2) There are many vertical oil and gas wells which exist in the 
reserve area of the Black Eagle mine.
    (3) The Black Eagle mine will employ the continuous mining room and 
pillar method of mining. It is expected that each vertical wellbore 
will only be mined through once in any seam.
    The petitioner proposes the following alternative method:
    (a) With respect to vertical mines, the petitioner proposes to 
modify 30 CFR 75.1700 to allow mining through vertical wellbores as 
encountered and whenever the safety barrier diameter is reduced to a 
distance less than the MSHA District Manager would approve pursuant to 
30 CFR 75.1700 for plugged oil or gas wells penetrating the Eagle Coal 
Seam and other mineable coal seams.
    (b) 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, and the depth of 
the well is less than 4,000 feet, the operator will clean the well from 
the surface to at least 200 feet below the lowest mineable coal seam's 
base. If the well depth is equal to or greater than 4,000 feet, the 
operator must clean out the well from the surface to at least 400 feet 
below the lowest mineable coal seam's base. The operator must remove 
all materials that are within the well, throughout the entire diameter 
of the well, and from wall to wall.
    (2) Down-hole logs will be prepared by the operator for each well. 
The logs, which collect subsurface information for each well, will use 
the following data measurement tools: a caliper survey, a gamma log, a 
bond log, and a deviation survey for determining the top and bottom of 
the lowest mineable coalbed, potential hydrocarbon producing strata, 
and the location for the bridge plug. If approved by the MSHA District 
Manager, down-hole camera surveys may be approved used instead of down-
hole logs. A journal will be maintained to describe the depth and 
nature of material(s) encountered, the drilling information, the length 
of the plug, casing(s) effected, and other information related to 
cleaning and sealing the well. This information will be kept for MSHA 
to inspect, should MSHA request it.
    (3) When cleaning the well, a diligent effort will be made to 
remove all the casing in the well. Once it is cleaned and the casings 
are removed, the well must be plugged by pumping cement slurry and 
pressurizing to 200 psi. If the casing cannot be removed, the remaining 
casing which remains will be cut, milled, perforated, or ripped to 
facilitate removing remaining casings. Any remaining casing must be 
perforated or ripped to allow cement to be injected in order to fill in 
voids throughout the well. Remaining casings must be perforated or 
ripped a minimum of 5 feet from 10 feet below to 10 feet above the coal 
seam. Perforations or rips are required at intervals spaced close 
enough (at least every 50 feet) to permit expanding cement slurry to 
infiltrate the annulus between the casing and the well wall for a 
distance of at least 200 feet below the base of the lowest mineable 
coalbed, for wells less than 4,000 feet deep and 400 feet below the 
lowest mineable coal seam, up to 100 feet above the uppermost part of 
the coal seam. If it is not possible to remove the casing, the operator 
will contact the MSHA District Manager before continuing work. If the 
well cannot be cleaned or the casing cannot be removed, then the 
operator must prepare the well as described above (if the well is less 
than 4,000 feet in depth) from the surface to at least 200 feet below 
the base of the lowest mineable seam; if the seam well is 4,000 feet or 
greater, then it must be prepared from the surface to 400 feet below 
the lowest mineable coal seam, unless the MSHA District Manager 
requires cleaning out the well due to a greater depth. If the operator 
can show, to the satisfaction of the MSHA District Manager, that the 
well is sealed properly, then the operator will not be required to 
perforate or rip the casings. A casing bond log is required for each 
casing and tubing string in lieu of ripping or perforating strings.
    (4) In the event that the cleaned-out well produces excessive 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 
coalbed, but above the top of the uppermost hydrocarbon-producing 
stratum, unless the MSHA District Manager requires a larger distance. 
If it is not possible to set a mechanical bridge plug, an appropriately 
sized packer may be used in place of the mechanical bridge plug. The 
mine operator must provide the MSHA District Manager will any 
information on the geological formation of the strata and the well 
pressure. The mine operator must record what actions have been taken to 
plug the hydrocarbon producing strata.
    (5) If the uppermost hydrocarbon-producing stratum is within 300 
feet of the base of the lowest mineable coalbed, properly placed 
mechanical bridge plugs or a suitable brush plug, described in 
subparagraph (b)(4) above, will be used to isolate the hydrocarbon-
producing stratum from the expanding cement plug. A minimum of 200 feet 
of expanding cement will be placed below the lowest mineable coalbed.
    (c) After cleaning out the well, as specified above, the petitioner 
proposes to use the following procedures when plugging or replugging 
oil and gas wells to the surface:
    (1) A cement plug will be set in the wellbore by pumping an 
expanding cement slurry down the well to create a plug that runs from 
at least 200 feet below the base of the coal seam that is being mined. 
The cement must be placed in the well under a pressure of at least 200 
pounds per square inch. Portland cement or a light-weight cement 
mixture may be used to fill in the area from approximately 100 feet 
above the top of the lowest mineable coalbed to the surface.
    (2) A small quantity of steel turnings, or other small magnetic 
particles, will be embedded in the top of the cement near the surface 
to serve as a permanent magnetic monument of the borehole.
    (d) The petitioner proposes to use the following procedures when 
plugging oil or gas wells for subsequent use as degasification 
boreholes:
    (1) A cement plug will be set 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 (400 feet if the depth is 4,000 
feet or greater) below the lowest mineable coalbed at a pressure of at 
least 200 pounds per square inch. The top of the expanding cement will 
extend upward at least 50 feet above the top of the coalbed being 
mined, unless the MSHA District Manager requires a greater distance.
    (2) The operator must grout a suitable casing into the bedrock of 
the upper part of the degasification well in order to protect it.
    (3) The operator must fit a wellhead to the top of the 
degasification casing, as required by the MSHA District Manager in the 
approved ventilation plan. This equipment can include check valves, 
shut-in valves, sampling ports,

[[Page 70571]]

flame arrestor equipment, and security fencing.
    (4) The degasification well must be addressed in the approved 
ventilation plan, including periodic tests of methane levels and limits 
on the minimum methane concentrations extracted.
    (5) Once an area of the coal mine is degassed by a sealed well or 
if the coal mine is abandoned, the operator must plug all 
degasification wells using the following procedures:
    (i) The operator must insert a tube to the bottom of the well, or 
at least to 100 feet above the coal seam being mined; blockage must be 
removed to allow the tube to reach this depth.
    (ii) The operator will set a cement plug in the well, pumping 
Portland cement or a lightweight cement mixture until the well is 
filled to the surface.
    (iii) The operator must embed steel turnings or other small 
magnetic particles in the top of the cement near the surface as 
permanent magnetic monuments for the well. An alternative is a 4 inch 
or larger casing, set in cement, which extends 36 or more inches above 
the ground level with the API number engraved or welded on the casing.
    (e) As an alternative procedure for preparing and plugging or 
replugging oil or gas wells that cannot be cleaned completely:
    (1) The operator must drill a hole adjacent and parallel to the 
well, at least 200 feet deep, below the coal seam to be mined or at the 
lowest mineable coal seam (whichever is lower). The operator will 
locating remaining casings using geophysical sensing devices.
    (2) If casings are detected then the operator must drill into the 
well from the parallel hole. Between 10 feet above to 10 feet below the 
coal seam, the operator must perforate or rip all casings every 5 feet. 
Beyond that distance, the operator must perforate or rip at every 50 
feet from at least 200 feet below the base of the coal seam to be mined 
or the lowest mineable coal seam, whichever is lower, up to 100 feet 
above the seam that is being mined.
    (3) The annulus between the degasification casing and the borehole 
wall will be cemented.
    (4) If there is insufficient casings in the well to allow for 
(e)(3) to be completed, the operator must use a horizontal hydrolic 
fracturing technique to intercept the original well.
    (5) The operator must prepare down-hole logs for each well 
consisting of a caliper survey, gamma log, a bond log, and a deviation 
survey for determining the diameters of the coal seam to be mined or 
the lowest mineable coal seam, whichever is lower.
    (6) A journal must be maintained to describe the depth and nature 
of material encountered, the drilling information, length of plug, 
casing(s) effected, and other information related to cleaning and 
sealing the well. This information will be kept for MSHA to inspect, 
should MSHA request it.
    (7) After the operator has plugged the well described in (e), the 
operator must plug the adjacent hole using Portland cement or a 
lightweight cement mixture.
    (8) The operator must embed steel turnings or other small magnetic 
particles in the top of the cement near the surface as permanent 
magnetic monuments for the well. An alternative is a 4 inch or larger 
casing, set in cement, which extends 36 or more inches above the ground 
level with the API number engraved or welded on the casing.
    (f) Once mining has been granted by the MSHA District Manager, the 
following procedures will take place:
    (1) A conference may be requested by any of the following: The 
representative of the miners, a state agency, or the MSHA District 
Manager. The conference will be scheduled by the MSHA District Manager, 
to review, evaluate, and accommodate any abnormal or unusual 
circumstances that relate to the condition of the well or surrounding 
strata.
    (2) The intersection of a well by the operator must be conducted on 
a shift approved by the MSHA District Manager. The operator must notify 
the MSHA District Manager and the miners' representative prior to the 
intersection so that representatives can be present.
    (3) Drivage sites must be installed by the operator not more than 
50 feet from the well, at the last open crosscut near the area to be 
mined to ensure intersection of the well. For longwall mining, distance 
markers will be installed on 5-foot centers 50 feet in advance of the 
well in the headgate entry and in the tailgate entry.
    (4) Firefighting equipment, including fire extinguishers, rock 
dust, and sufficient fire hose to reach the working face area of the 
mining-through will be available when either the conventional or 
continuous mining method is used. The fire hose will be located in the 
last open crosscut of the entry or room. The operator will maintain the 
water line to be able to reach the farthest point of penetration on the 
section.
    (5) Sufficient supplies of roof support and ventilation materials 
will be available and located at the last open crosscut. In addition, 
an emergency plug and/or plugs will be available in the immediate area 
of the mine-through.
    (6) Equipment will be checked for permissibility and serviced on 
the shift prior to mining-through the well; water sprays, water 
pressures and water flow rates will be checked and any issues will be 
corrected.
    (7) The methane monitor on the continuous mining machine will be 
calibrated on the shift prior to mining-through the well.
    (8) When mining is in progress, tests for methane will be made with 
a hand-held methane detector at least every 10 minutes from the time 
that mining with the continuous mining machine is within 30 feet of the 
well until the well is intersected and immediately prior to mining 
through. During the actual cutting through process, no individual will 
be allowed on the return side until mining-through has been completed 
and the area has been examined and declared safe.
    (9) The working place will be free from accumulations of coal dust 
and coal spillages, and rock dust will be placed on the roof, rib and 
floor within 20 feet of the face when mining through or near the well 
on the shift or shifts during which the cut-through will occur.
    (10) When the wellbore is intersected, all equipment will be 
deenergized and the area thoroughly examined and determined safe before 
mining is resumed.
    (11) After a well has been intersected and the working place 
determined safe, mining will continue inby the well at a sufficient 
distance to permit adequate ventilation around the area of the 
wellbore.
    (12) When a torch is necessary for poorly cut or milled casings, no 
open flames will be permitted in the area until adequate ventilation 
has been established around the wellbore and methane levels of less 
than 1 percent are present in all areas affected by flames or sparks 
from the torch.
    (13) Non-sparking (brass) tools will be used only to expose and 
examine cased wells. These tools will be located on the working 
section.
    (14) No person will be permitted in the area of the mining-through 
operation except for those actually engaged in the operation, company 
personnel, representatives of the miners, personnel from MSHA, and 
personnel from the appropriate State agency.
    (15) The operator must alert all personnel in the mine of a planned 
intersection of the well before going underground if it is to occur 
during the shift.

[[Page 70572]]

    (16) The mining-through operation will be under the direct 
supervision of a certified official. Instructions concerning the 
mining-through operation will be issued only by the certified official 
in charge.
    (17) If the mine operator cannot find the well or if the 
anticipated intersection is missed, the operator must cease mining to 
assess for hazardous conditions, notify the MSHA District Manager, and 
use reasonable methods of locating the well. If the well cannot be 
located, the mine operator must notify the MSHA District Manager to 
resolve issues before mining resumes.
    (18) This modification does not affect the ability for MSHA 
representatives to interrupt or halt well intersection or to issue a 
withdrawal notice when deemed necessary. MSHA may issue a withdrawal of 
persons in the mine or a cessation of the well intersection verbally or 
by written order, including the basis for the order. The MSHA 
representative then needs to permit resumption for mining operations in 
the affected area to restart.
    (19) If the well is not plugged to the depth of all mineable coal 
seams that have been identified in the core hole logs, then any coal 
seams below the lowest plug will remain subject to the barrier 
requirements dictated by 30 CFR 75.1700, if developed in the future.
    (20) All involved miners will be trained on the contents of this 
petition prior to starting the process of plugging or re-plugging.
    (21) Mechanical bridge plugs will utilize the best available 
technologies required or recognized by the state regulatory agency and/
or the oil and gas industry.
    (22) Within 30 days after the Proposed Decision and Order (PDO) 
becomes final, the operator will submit proposed revisions to be 
approved by the MSHA District Manager, as part of the 30 CFR 48 
training plan. This will include initial and refresher training. The 
revisions are to include training on the above terms for all miners 
involved in well intersection prior to mining within 150 feet of the 
well which is to be mined through.
    (23) The required person under 30 CFR 75.1501 Emergency Evacuations 
is responsible for emergencies relating to the intersection and this 
person will review intersection procedures before the intersection 
occurs.
    (24) Within 30 days of when this PDO is finalized, the operator 
will submit a revised emergency evacuation and firefighting training 
program, required by 30 CFR 75.1502. The operator must revise the 
program to incorporate hazards and evacuation plans used for well 
intersection. All underground miners will be trained in the above plan 
revisions within 30 days of submittal.
    (25) The petitioner asserts that the proposed alternative method 
will at all times guarantee no less than the same measure of protection 
from the potential hazards against which the existing standard for 30 
CFR 75.1700 is intended to guard.
