SUPPLEMENTARY INFORMATION: Section
101(c) of the Federal Mine Safety and
Health Act of 1977 and title 30 of the
Code of Federal Regulations (CFR) 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. The application of such standard to
such mine will result in a diminution of
safety to the miners in such mine.
In addition, sections 44.10 and 44.11
of 30 CFR establish the requirements for
filing petitions for modification.

II. Petition for Modification
Docket Number: M–2024–012–C.
Petitioner: Rockwell Mining, LLC,
4619 Bolt Road, Bolt, WV 25817.
Mine: Eagle #3 Mine, MSHA ID No.
46–09427, located in Wyoming County,
West Virginia.
Regulation Affected: 30 CFR 75.1700,
Oil and gas wells.
Modification Request: The petitioner
requests a modification of 30 CFR
75.1700 as it relates to oil and gas wells
at the mine. Specifically, the petitioner
is petitioning to mine within the 300feet barrier established by 30 CFR
75.1700.
The petitioner states that:
(a) Rockwell operates one continuous
miner super section with two
continuous miners. The mining is in the
lower Eagle seam. There is no
undermining at Eagle #3 mine. In the
area of the gas wells, there is
overmining in the No. 2 gas seam by
Kopperston No. 2 mine. There is over
mining in the Upper Eagle seam but not
in the area of the wells.
(b) The planning and configuration of
a set of the mains entries is between two
abandoned mines. Such mains will
VerDate Sep<11>2014
17:23 Oct 07, 2024
Jkt 265001
encounter three and perhaps more gas
wells drilled through lower Eagle coal
seam. One such well is active and two
are abandoned. All such wells will need
to be plugged so that they can be mined
through.
(c) Rockwell expects to encounter
such wells within 6 months.
(d) The petition addresses items for
which District Manager approval is
required: procedures for cleaning out
and preparing oil and gas wells prior to
plugging or re-plugging; procedures for
plugging or re-plugging oil or gas wells
to the surface; procedures for plugging
or re-plugging oil or gas wells for use as
degasification boreholes, alternative
procedures for preparing and plugging
or re-plugging oil or gas wells; and
procedures after approval has been
granted to mine through a plugged or replugged well.
(e) The type of oil or gas well that will
be considered under this Petition
includes: wells that have been depleted
of oil or gas production or have not
produced oil or gas and that may have
been plugged; or active conventional
vertical wells which are not producing
gas or oil, subject to the provisions
below. Unconventional wells in the
Marcellus or Utica and all other
unconventional shale oil and gas wells
are not subject to this modification.
Nothing in these provisions is meant to
lessen, diminish, or substitute any
provision found in applicable state laws
or regulations.
(f) Although some gas wells were
present in the northern reserve, the
mine plan includes the use and
maintenance of barriers in accordance
with state and federal regulations. At
that time, the mine reserve was large
enough to allow for mining ‘‘around’’
the established barriers. Now that
mining in the northern reserve has been
exhausted, the additional mining will be
completed in the southern portion of the
reserve. The mine is actively developing
a new center ridge corridor between an
older abandoned mine (Ranger Fuel
Corp. E- Mine) and the coal seam
outcrop. Maintaining a 300-foot barrier
in this area makes it impossible to gain
access to the remaining reserves in the
mine. The map titled ‘‘Eagle No. 3
Mine—MINE MAP’’ shows the current
mining in this area with the projected
mining inby the gas wells. The corridor
development will cease at break 29 until
a Proposed Decision and Order (PDO) is
granted by MSHA. Until such time, the
active producing section (MMU–001
and MMU–002) will relocate to a small
reserve area outby the active faces.
Rockwell Mining, LLC, is submitting a
petition for modification to allow for the
plugging of and mining through these
PO 00000
Frm 00152
Fmt 4703
Sfmt 4703
gas wells and to significantly reduce the
barrier and mine around the wells, if
possible. The alternative method of
plugging the wells shall not compromise
the protection to miners. The plugging
of wells to this excepted standard
ensures the safety of our miners and
extends the life of the mine. Without the
ability to extend the corridor to the
south, the mine will cease operations
sooner than anticipated, after it has
exhausted the reserves outby break 29.
(g) The alternative method provides
an equivalent level of protection as
many previous petitions. It permits
identification of wells and contains
provisions that prevent the introduction
of methane or natural gas within the
mine by appropriate and extensive
plugging of the wells. Additional
precautions provide for the detection of
gas and the prevention of accumulations
of gas with oversight by MSHA.
The petitioner proposes the following
alternative method:
(a) A safety barrier of 300 feet in
diameter (150 feet between any mined
area and a well) shall be maintained
around all oil and gas wells (defined
herein to include all active, inactive,
abandoned, shut-in, previously plugged
wells, water injection wells, and carbon
dioxide sequestration wells) until
approval to proceed with mining has
been obtained from the District
Manager.
(b) Prior to mining within the 300-feet
safety barrier around any well that the
mine plans to intersect, the mine
operator shall provide to the District
Manager a sworn affidavit or declaration
executed by a company official stating
that all mandatory procedures for
cleaning out, preparing, and plugging
each gas or oil well have been
completed as described by the terms
and conditions of the PDO granted by
MSHA. The affidavit or declaration
must be accompanied by all logs
described in the PDO granted by MSHA
and any other records that the District
Manager may request. Once approved
by the District Manager, the mine
operator may mine within the safety
barrier of the well, subject to the terms
of the PDO granted by MSHA.
(c) If well intersection is not planned,
the mine operator may request a permit
to reduce the 300-feet diameter of the
safety barrier that does not include
intersection of the well. The District
Manager may require documents and
information that help verify the
accuracy of the location of the well with
respect to the mine maps and mining
projections, including survey closure
data, down-hole well deviation logs,
historical well intersection location
data. If the District Manager approves,

08OCN1
ddrumheller on DSK120RN23PROD with NOTICES1
Federal Register / Vol. 89, No. 195 / Tuesday, October 8, 2024 / Notices
the mine operator may then mine within
the safety barrier of the well.
(d) In the event an uncharted well is
inadvertently mined into, mining shall
cease immediately on the section,
electrical power shall be deenergized in
the affected area, and MSHA shall be
notified immediately via the emergency
phone number posted on MSHA’s
website for reporting of this hazardous
condition. In addition to its potential for
liberating methane, the well may also be
an open connection from the mine to
the surface that presents a hazard to the
mine and the environment. The District
will respond with a timely
investigation, issue a K Order if needed,
and allow resumption of mining once a
suitable action plan is in place.
(e) The terms and conditions of the
PDO granted by MSHA shall apply to all
types of underground coal mining.
(f) The following procedures shall be
followed for cleaning out and preparing
vertical oil and gas wells prior to
plugging or re-plugging:
(1) The mine operator shall test for gas
emissions inside the hole before
cleaning out, preparing, plugging, and
re-plugging oil and gas wells. The
District Manager shall be contacted if
gas is being produced.
(2) A diligent effort shall be made to
clean the well to the original total
depth. The mine operator shall contact
the District Manager prior to stopping
the operation to pull casing or clean out
the total depth of the well. If this depth
cannot be reached, and the total depth
of the well is less than 4,000 feet, the
operator shall completely clean out the
well from the surface to at least 200 feet
below the base of the lowest mineable
coal seam, unless the District Manager
requires cleaning to a greater depth
based on the geological strata or
pressure within the well. The operator
shall provide the District Manager with
all information it possesses concerning
the geological nature of the strata and
the pressure of the well. If the total
depth of the well is 4,000 feet, or
greater, the operator shall completely
clean out the well from the surface to at
least 400 feet below the base of the
lowest mineable coal seam. The
operator shall remove all material from
the entire diameter of the well, wall to
wall. If the total depth of the well is
unknown and there is no historical
information, the mine operator must
contact the District Manager before
proceeding.
(3) The operator shall prepare downhole logs for each well. Logs shall
consist of a caliper survey, a gamma log,
a bond log and a deviation survey for
determining the top, bottom, and
thickness of all coal seams down to the
VerDate Sep<11>2014
17:23 Oct 07, 2024
Jkt 265001
lowest minable coal seam, potential
hydrocarbon producing strata and the
location of any existing bridge plug. In
addition, a journal shall be maintained
describing the depth of each material
encountered; the nature of each material
encountered; bit size and type used to
drill each portion of the hole; length and
type of each material used to plug the
well; length of casing(s) removed,
perforated or ripped or left in place; any
section where casing was cut or milled;
and other pertinent information
concerning cleaning and sealing the
well. Invoices, workorders, and other
records relating to all work on the well
shall be maintained as part of the logs
and provided to MSHA upon request.
(4) When cleaning out the well as
detailed in subparagraph (f)(2), the
operator shall make a diligent effort to
remove all of the casing in the well.
After the well is completely cleaned out
and all the casing removed, the well
should be plugged to the total depth by
pumping expanding cement slurry and
pressurizing to at least 200 pounds per
square inch (psi). If the casing cannot be
removed, it must be cut, milled,
perforated or ripped at all mineable coal
seam levels to facilitate the removal of
any remaining casing in the coal seam
by the mining equipment. Any casing
which remains shall be perforated or
ripped to permit the injection of cement
into voids within and around the well.
All casing remaining at mineable coal
seam levels shall be perforated or ripped
at least every 5 feet from 10 feet below
the coal seam to 10 feet above the coal
seam.
(5) Perforations or rips are required at
least every 50 feet from 200 feet (400
feet if the total well depth is 4,000 feet
or greater) below the base of the lowest
mineable coal seam up to 100 feet above
the uppermost mineable coal seam. The
mine operator shall take appropriate
steps to ensure that the annulus
between the casing and the well walls
are filled with expanding (minimum 0.5
percent expansion upon setting) cement
and contain no voids.
(6) If it is not possible to remove all
of the casing, the operator shall notify
the District Manager before any other
work is performed. If the well cannot be
cleaned out or the casing removed, the
operator shall prepare the well as
described from the surface to at least
200 feet below the base of the lowest
mineable coal seam for wells less than
4,000 feet in depth and 400 feet below
the lowest mineable coal seam for wells
4,000 feet or greater, unless the District
Manager requires cleaning out and
removal of casing to a greater depth
based on geological strata or the
pressure within the well.

(7) If the operator, using a casing bond
log, can demonstrate to the satisfaction
of the District Manager that all annuli in
the well are already adequately sealed
with cement, the operator will not be
required to perforate or rip the casing
for that particular well. When multiple
casing and tubing strings are present in
the coal horizon(s), any remaining
casing shall be ripped or perforated;
then it shall be filled with expanding
cement as indicated above. An
acceptable casing bond log for each
casing and tubing string is needed if
used in lieu of ripping or perforating
multiple strings.
(8) If the District Manager concludes
that the completely cleaned out well is
emitting excessive amounts of gas, the
operator must place a mechanical bridge
plug in the well. It must be placed in a
competent stratum at least 200 feet (400
feet if the total well depth is 4,000 feet
or greater) below the base of the lowest
mineable coal seam, but above the top
of the uppermost hydrocarbonproducing stratum, unless the District
Manager requires a greater distance
based on geological strata the pressure
within the well. The operator shall
provide the District Manager with all
information it possesses concerning the
geological nature of the strata and the
pressure of the well. If it is not possible
to set a mechanical bridge plug, an
appropriately sized packer shall be
used. The mine operator shall document
what has been done to ‘‘kill the well’’
and plug the carbon producing strata.
(9) If the upper-most hydrocarbonproducing stratum is within 300 feet of
the base of the lowest minable coal
seam, the operator shall properly place
mechanical bridge plugs as described in
subparagraph (f)(8) to isolate the
hydrocarbon- producing stratum from
the expanding cement plug. The
operator shall place a minimum of 200
feet (400 feet if the total well depth is
4,000 feet or greater) of expanding
cement below the lowest mineable coal
seam, unless the District Manager
requires a greater distance based on the
geological strata or the pressure within
the well.
(g) The following procedures shall be
followed for plugging or re-plugging oil
or gas wells to the surface after
completely cleaning out the well as
previously specified:
(1) The operator shall pump
expanding cement slurry down the well
to form a plug which runs from at least
200 feet (400 feet if the total well depth
is 4,000 feet or greater) below the base
of the lowest mineable coal seam (or
lower if required by the District
Manager based on the geological strata
or the pressure within the well) to the

surface. The expanding cement shall be
placed in the well under a pressure of
at least 200 psi.
(2) Portland cement or a lightweight
cement mixture shall be used to fill the
area from 100 feet above the top of the
uppermost mineable coal seam (or
higher if required by the District
Manager that a higher distance is
required due to the geological strata or
the pressure within the well) to the
surface.
(3) The operator shall embed steel
turnings or other small magnetic
particles in the top of the cement near
the surface to serve as a permanent
magnetic monument of the well. In the
alternative, a 4-inch or larger diameter
casing, set in cement, shall extend at
least 36 inches above the ground level
with the American Petroleum Institute
(API) well number engraved or welded
on the casing. When the hole cannot be
marked with a physical monument (e.g.,
prime farmland), high-resolution GPS
coordinates (one-half meter resolution)
shall be required.
(h) The following procedures shall be
followed for plugging or re-plugging oil
and gas wells for use as degasification
wells after completely cleaning out the
well as previously specified:
(1) The operator shall set a cement
plug in the well by pumping an
expanding cement slurry down the
tubing to provide at least 200 feet (400
feet if the total well depth is 4,000 feet
or greater) of expanding cement below
the lowest mineable coal seam, unless
the District Manager requires a greater
depth based on the geological strata or
the pressure within the well. The
expanding cement shall be placed in the
well under a pressure of at least 200 psi.
The top of the expanding cement shall
extend at least 50 feet above the top of
the coal seam being mined, unless the
District Manager requires a greater
distance based on the geological strata
or the pressure within the well.
(2) The operator shall securely grout
into the bedrock of the upper portion of
the degasification well a suitable casing
to protect it. The remainder of this well
may be cased or uncased.
(3) The operator shall fit the top of the
degasification casing with a wellhead
equipped as required by the District
Manager in the approved ventilation
plan. Such equipment may include
check valves, shut-in valves, sampling
ports, flame arrestor equipment, and
security fencing.
(4) Operation of the degasification
well shall be addressed in the approved
ventilation plan. This may include
periodic tests of methane levels and
limits on the minimum methane
concentrations that may be extracted.

Jkt 265001
(5) After the area of the coal mine that
is degassed by a well is sealed or the
coal mine is abandoned, the operator
must plug all degasification wells using
the following procedures:
(i) The operator shall insert a tube to
the bottom of the well or, if not possible,
to within 100 feet above the coal seam
being mined. Any blockage must be
removed to ensure that the tube can be
inserted to this depth.
(ii) The operator shall set a cement
plug in the well by pumping Portland
cement or a lightweight cement mixture
down the tubing until the well is filled
to the surface.
(iii) The operator shall embed steel
turnings or other small magnetic
particles in the top of the cement near
the surface to serve as a permanent
magnetic monument of the well. In the
alternative, a 4-inch or larger casing, set
in cement, shall extend at least 36
inches above the ground level with the
API well number engraved or welded on
the casing.
(i) The following provisions apply to
all wells which the operator determines,
and with which the MSHA District
Manager agrees, cannot be completely
cleaned out due to damage to the well
caused by subsidence, caving, or other
factors.
(1) The operator shall drill a hole
adjacent and parallel to the well, to a
depth of at least 200 feet (400 feet if the
total well depth is 4,000 feet or greater)
below the lowest mineable coal seam,
unless the District Manager requires a
greater depth based on the geological
strata or the pressure within the well.
(2) The operator shall use a
geophysical sensing device to locate any
casing which may remain in the well.
(3) If the well contains casing(s), the
operator shall drill into the well from
the parallel hole. From 10 feet below the
coal seam to 10 feet above the coal
seam, the operator shall perforate or rip
all casings at least every 5 feet. Beyond
this distance, the operator shall
perforate or rip at least every 50 feet
from at least 200 feet (400 feet if the
total well depth is 4,000 feet or greater)
below the base of the lowest mineable
coal seam up to 100 feet above the seam
being mined, unless the District
Manager requires a greater distance
based on the geological strata or the
pressure within the well. The operator
shall fill the annulus between the
casings and between the casings and the
well wall with expanding (minimum 0.5
percent expansion upon setting) cement
and shall ensure that these areas contain
no voids. If the operator, using a casing
bond log, can demonstrate to the
satisfaction of the District Manager that
the annulus of the well is adequately
PO 00000
Frm 00154
Fmt 4703
Sfmt 4703
sealed with cement, then the operator
shall not be required to perforate or rip
the casing for that particular well or fill
these areas with cement. When multiple
casing and tubing strings are present in
the coal horizon(s), any casing which
remains shall be ripped or perforated
and filled with expanding cement as
indicated. An acceptable casing bond
log for each casing and tubing string
shall be made if this used in lieu of
ripping or perforating multiple strings.
(4) Where the operator determines,
and the District Manager agrees, that
there is insufficient casing in the well to
allow the method outlined to be used,
then the operator shall use a horizontal
hydraulic fracturing technique to
intercept the original well. From at least
200 feet (400 feet if the total well depth
is 4,000 feet or greater) below the base
of the lowest mineable coal seam to a
point at least 50 feet above the seam
being mined, the operator shall fracture
in at least six places at intervals to be
agreed upon by the operator and the
District Manager after considering the
geological strata and the pressure within
the well. The operator shall pump
expanding cement into the fractured
well in sufficient quantities and in a
manner which fills all intercepted
voids.
(5) The operator shall prepare downhole logs for each well. Logs shall
consist of a caliper survey, a gamma log,
a bond log and a deviation survey for
determining the top, bottom, and
thickness of all coal seams down to the
lowest minable coal seam, potential
hydrocarbon producing strata and the
location of any existing bridge plug. The
operator may obtain the logs from the
adjacent hole rather than the well if the
condition of the well makes it
impractical to insert the equipment
necessary to obtain the log.
(6) A journal shall be maintained that
describes: the depth of each material
encountered; the nature of each material
encountered; bit size and type used to
drill each portion of the hole; length and
type of each material used to plug the
well; length of casing(s) removed,
perforated or ripped or left in place; any
sections where casing was cut or milled;
and other pertinent information
concerning sealing the well. Invoices,
workorders, and other records relating
to all work on the well shall be
maintained as part of this journal and
provided to MSHA upon request.
(7) After the operator has plugged the
well, the operator shall plug the
adjacent hole, from the bottom to the
surface, with Portland cement or a
lightweight cement mixture. The
operator shall embed steel turnings or
other small magnetic particles in the top

of the cement near the surface to serve
as a permanent magnetic monument of
the well. In the alternative, a 4-inch or
larger casing, set in cement, shall extend
at least 36 inches above the ground
level. A combination of the methods
outlined previously may have to be used
in a single well, depending upon the
conditions of the hole and the presence
of casings. The operator and the District
Manager shall discuss the nature of each
hole and if the District Manager requires
more than one method be utilized. The
mine operator may submit an alternative
plan to the District Manager for
approval to use different methods
including certification by a registered
petroleum engineer to support the
proposed alternative methods to address
wells that cannot be completely cleaned
out.
(j) The following procedures shall be
followed when mining within a 100-feet
diameter barrier around a well.
(1) A representative of the operator, a
representative of the miners, the
appropriate State agency, or the MSHA
District Manager may request that a
conference be conducted prior to
intersecting any plugged or re-plugged
well. The party requesting the
conference shall notify all other parties
listed above within a reasonable time
prior to the conference to provide
opportunity for participation. The
purpose of the conference shall be to
review, evaluate, and accommodate any
abnormal or unusual circumstance
related to the condition of the well or
surrounding strata when such
conditions are encountered.
(2) The operator shall intersect a well
on a shift approved by the District
Manager. The operator shall notify the
District Manager and the miners’
representative in sufficient time prior to
intersecting a well to provide an
opportunity to have representatives
present.
(3) When using continuous mining
methods, the operator shall install
drivage sights at the last open crosscut
near the place to be mined to ensure
intersection of the well. The drivage
sites shall not be more than 50 feet from
the well. When using longwall mining
methods, distance markers shall be
installed on 5-foot centers for a distance
of 50 feet in advance of the well in the
headgate entry and in the tailgate entry.
(4) The operator shall ensure that firefighting equipment including fire
extinguishers, rock dust, and sufficient
fire hose to reach the working face area
of the well intersection (when either the
conventional or continuous mining
method is used) is available and
operable during all well intersections.
The fire hose shall be located in the last
VerDate Sep<11>2014
17:23 Oct 07, 2024
Jkt 265001
open crosscut of the entry or room. The
operator shall maintain the water line to
the belt conveyor tailpiece along with a
sufficient amount of fire hose to reach
the farthest point of penetration on the
section. When the longwall mining
method is used, a hose to the longwall
water supply is sufficient.
(5) The operator shall ensure that
sufficient supplies of roof support and
ventilation materials shall be available
and located at the last open crosscut. In
addition, emergency plugs and suitable
sealing materials shall be available in
the immediate area of the well
intersection.
(6) On the shift prior to intersecting
the well, the operator shall service all
equipment and check it for
permissibility. Water sprays, water
pressures, and water flow rates used for
dust and spark suppression shall be
examined and any deficiencies
corrected.
(7) The operator shall calibrate the
methane monitor(s) on the longwall,
continuous mining machine, or cutting
machine and loading machine on the
shift prior to intersecting the well.
(8) When mining is in progress, the
operator shall perform tests for methane
with a handheld methane detector at
least every 10 minutes from the time
that mining with the continuous mining
machine or longwall face is within 30
feet of the well until the well is
intersected. During the actual cutting
process, no individual shall be allowed
on the return side until the well
intersection has been completed and the
area has been examined and declared
safe. All workplace examinations on the
return side of the shearer shall be
conducted while the shearer is idle. The
operator’s most current approved
ventilation plan shall be followed at all
times unless the District Manager
requires a greater air velocity for the
intersect.
(9) When using continuous or
conventional mining methods, the
working place shall be free from
accumulations of coal dust and coal
spillages, and rock dust shall be placed
on the roof, rib, and floor to within 20
feet of the face when intersecting the
well. On longwall sections, rock dusting
shall be conducted and placed on the
roof, rib, and floor up to both the
headgate and tailgate gob.
(10) When the well is intersected, the
operator shall de-energize all
equipment, and thoroughly examine
and determine the area to be safe before
permitting mining to resume.
(11) After a well has been intersected
and the working place determined to be
safe, mining shall continue inby the
well a sufficient distance to permit
PO 00000
Frm 00155
Fmt 4703
Sfmt 4703
81571
adequate ventilation around the area of
the well.
(12) When necessary, torches shall be
used for inadequately or inaccurately
cut or milled casings. No open flame
shall be permitted in the area until
adequate ventilation has been
established around the well bore and
methane levels of less than 1.0 percent
are present in all areas that will be
exposed to flames and sparks from the
torch. The operator shall apply a thick
layer of rock dust to the roof, face, floor,
ribs and any exposed coal within 20 feet
of the casing prior to the use of torches.
(13) Non-sparking (brass) tools shall
be located on the working section and
shall be used exclusively to expose and
examine cased wells.
(14) No person shall be permitted in
the area of the well intersection except
those engaged in the operation,
company personnel, representatives of
the miners, personnel from MSHA, and
personnel from the appropriate State
agency.
(15) The operator shall alert all
personnel in the mine to the planned
intersection of the well prior to their
going underground if the planned
intersection is to occur during their
shift. This warning shall be repeated for
all shifts until the well has been mined
through.
(16) The well intersection shall be
under the direct supervision of a
certified individual. Instructions
concerning the well intersection shall be
issued only by the certified individual
in charge.
(17) If the mine operator cannot find
the well in the middle of the panel or
a gate section misses the anticipated
intersection, mining shall cease and the
District Manager shall be notified.
(18) A copy of the PDO granted by
MSHA shall be maintained at the mine
and be available to the miners.
(19) If the well is not plugged to the
total depth of all minable coal seams
identified in the core hole logs, any coal
seams beneath the lowest plug shall
remain subject to the barrier
requirements of 30 CFR 75.1700.
(20) All necessary safety precautions
and safe practices required by MSHA
regulations and State regulatory
agencies having jurisdiction over the
plugging site shall be followed.
(21) All miners involved in the
plugging or re-plugging operations shall
be trained on the contents of the PDO
granted by MSHA prior to starting the
process.
(22) Mechanical bridge plugs should
incorporate the best available
technologies required or recognized by
the State regulatory agency and/or oil
and gas industry.

(23) Within 30 days after the PDO
granted by MSHA becomes final, the
operator shall submit proposed
revisions for its approved 30 CFR part
48 training plan to the District Manager.
These proposed revisions shall include
initial and refresher training on
compliance with the terms and
conditions stated in the PDO granted by
MSHA. The operator shall provide all
miners involved in well intersection
with training on the requirements of the
PDO granted by MSHA prior to mining
within 150 feet of a well intended to be
mined through.
(24) The responsible person required
under 30 CFR 75.1501 shall be
responsible for well intersection
emergencies. The well intersection
procedures shall be reviewed by the
responsible person prior to any planned
intersection.
(25) Within 30 days after the PDO
granted by MSHA becomes final, the
operator shall submit proposed
revisions for its approved mine
emergency evacuation and firefighting
program of instruction required under
30 CFR 75.1502. The operator shall
revise the program of instruction to
include the hazards and evacuation
procedures to be used for well
intersections. All underground miners
shall be trained in this revised plan
within 30 days of submittal.
(k) The miners at the Eagle #3 mine
are not represented by a labor union and
do not have a miner’s representative.
The petition is posted at the mine.
In support of the proposed alternative
method, the petitioner has also
submitted: mine maps indicating well
locations, current mining in the area
and projected mining inby the gas wells;
well production records and charts;
schematics showing general crosssections of casing and tubing; and other
relevant facts.
The petitioner asserts that the
alternative method proposed will at all
times guarantee no less than the same
measure of protection afforded the
miners under the mandatory standard.

and the 3M Versaflo TR–800
Intrinsically Safe PAPR motor/blower
and battery with battery pack.
The petitioner states that:
(a) The 3M Versaflo TR–800 PAPR
with motor/blower and battery qualifies
as intrinsically safe.
(b) The CleanSpace EX PAPR also
qualifies as intrinsically safe.
(c) Both the CleanSpace EX and the
3M Versaflo TR–800 PAPRs provide a
constant flow of air inside the mask or
helmet. This airflow provides
respiratory protection and comfort in
hot working conditions.
(d) Neither the 3M Versaflo TR–800
nor the CleanSpace EX PAPR is MSHAapproved as permissible.
(e) Neither the 3M nor the CleanSpace
is pursuing MSHA approval.
(f) River View Coal currently makes
available to all miners NIOSH-approved
high efficiency l00 series respirators to
protect the miners against potential
exposure to respirable coal mine dust,
including crystalline silica, during

SUPPLEMENTARY INFORMATION: Section 101(c) of the Federal Mine Safety
and Health Act of 1977 and title 30 of the Code of Federal Regulations
(CFR) 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. The application of such standard to such mine will result in a
diminution of safety to the miners in such mine.
In addition, sections 44.10 and 44.11 of 30 CFR establish the
requirements for filing petitions for modification.
II. Petition for Modification
Docket Number: M-2024-012-C.
Petitioner: Rockwell Mining, LLC, 4619 Bolt Road, Bolt, WV 25817.
Mine: Eagle #3 Mine, MSHA ID No. 46-09427, located in Wyoming
County, West Virginia.
Regulation Affected: 30 CFR 75.1700, Oil and gas wells.
Modification Request: The petitioner requests a modification of 30
CFR 75.1700 as it relates to oil and gas wells at the mine.
Specifically, the petitioner is petitioning to mine within the 300-feet
barrier established by 30 CFR 75.1700.
The petitioner states that:
(a) Rockwell operates one continuous miner super section with two
continuous miners. The mining is in the lower Eagle seam. There is no
undermining at Eagle #3 mine. In the area of the gas wells, there is
overmining in the No. 2 gas seam by Kopperston No. 2 mine. There is
over mining in the Upper Eagle seam but not in the area of the wells.
(b) The planning and configuration of a set of the mains entries is
between two abandoned mines. Such mains will encounter three and
perhaps more gas wells drilled through lower Eagle coal seam. One such
well is active and two are abandoned. All such wells will need to be
plugged so that they can be mined through.
(c) Rockwell expects to encounter such wells within 6 months.
(d) The petition addresses items for which District Manager
approval is required: procedures for cleaning out and preparing oil and
gas wells prior to plugging or re-plugging; procedures for plugging or
re-plugging oil or gas wells to the surface; procedures for plugging or
re-plugging oil or gas wells for use as degasification boreholes,
alternative procedures for preparing and plugging or re-plugging oil or
gas wells; and procedures after approval has been granted to mine
through a plugged or re- plugged well.
(e) The type of oil or gas well that will be considered under this
Petition includes: wells that have been depleted of oil or gas
production or have not produced oil or gas and that may have been
plugged; or active conventional vertical wells which are not producing
gas or oil, subject to the provisions below. Unconventional wells in
the Marcellus or Utica and all other unconventional shale oil and gas
wells are not subject to this modification. Nothing in these provisions
is meant to lessen, diminish, or substitute any provision found in
applicable state laws or regulations.
(f) Although some gas wells were present in the northern reserve,
the mine plan includes the use and maintenance of barriers in
accordance with state and federal regulations. At that time, the mine
reserve was large enough to allow for mining ``around'' the established
barriers. Now that mining in the northern reserve has been exhausted,
the additional mining will be completed in the southern portion of the
reserve. The mine is actively developing a new center ridge corridor
between an older abandoned mine (Ranger Fuel Corp. E- Mine) and the
coal seam outcrop. Maintaining a 300-foot barrier in this area makes it
impossible to gain access to the remaining reserves in the mine. The
map titled ``Eagle No. 3 Mine--MINE MAP'' shows the current mining in
this area with the projected mining inby the gas wells. The corridor
development will cease at break 29 until a Proposed Decision and Order
(PDO) is granted by MSHA. Until such time, the active producing section
(MMU-001 and MMU-002) will relocate to a small reserve area outby the
active faces. Rockwell Mining, LLC, is submitting a petition for
modification to allow for the plugging of and mining through these gas
wells and to significantly reduce the barrier and mine around the
wells, if possible. The alternative method of plugging the wells shall
not compromise the protection to miners. The plugging of wells to this
excepted standard ensures the safety of our miners and extends the life
of the mine. Without the ability to extend the corridor to the south,
the mine will cease operations sooner than anticipated, after it has
exhausted the reserves outby break 29.
(g) The alternative method provides an equivalent level of
protection as many previous petitions. It permits identification of
wells and contains provisions that prevent the introduction of methane
or natural gas within the mine by appropriate and extensive plugging of
the wells. Additional precautions provide for the detection of gas and
the prevention of accumulations of gas with oversight by MSHA.
The petitioner proposes the following alternative method:
(a) A safety barrier of 300 feet in diameter (150 feet between any
mined area and a well) shall be maintained around all oil and gas wells
(defined herein to include all active, inactive, abandoned, shut-in,
previously plugged wells, water injection wells, and carbon dioxide
sequestration wells) until approval to proceed with mining has been
obtained from the District Manager.
(b) Prior to mining within the 300-feet safety barrier around any
well that the mine plans to intersect, the mine operator shall provide
to the District Manager a sworn affidavit or declaration executed by a
company official stating that all mandatory procedures for cleaning
out, preparing, and plugging each gas or oil well have been completed
as described by the terms and conditions of the PDO granted by MSHA.
The affidavit or declaration must be accompanied by all logs described
in the PDO granted by MSHA and any other records that the District
Manager may request. Once approved by the District Manager, the mine
operator may mine within the safety barrier of the well, subject to the
terms of the PDO granted by MSHA.
(c) If well intersection is not planned, the mine operator may
request a permit to reduce the 300-feet diameter of the safety barrier
that does not include intersection of the well. The District Manager
may require documents and information that help verify the accuracy of
the location of the well with respect to the mine maps and mining
projections, including survey closure data, down-hole well deviation
logs, historical well intersection location data. If the District
Manager approves,
[[Page 81569]]
the mine operator may then mine within the safety barrier of the well.
(d) In the event an uncharted well is inadvertently mined into,
mining shall cease immediately on the section, electrical power shall
be deenergized in the affected area, and MSHA shall be notified
immediately via the emergency phone number posted on MSHA's website for
reporting of this hazardous condition. In addition to its potential for
liberating methane, the well may also be an open connection from the
mine to the surface that presents a hazard to the mine and the
environment. The District will respond with a timely investigation,
issue a K Order if needed, and allow resumption of mining once a
suitable action plan is in place.
(e) The terms and conditions of the PDO granted by MSHA shall apply
to all types of underground coal mining.
(f) The following procedures shall be followed for cleaning out and
preparing vertical oil and gas wells prior to plugging or re-plugging:
(1) The mine operator shall test for gas emissions inside the hole
before cleaning out, preparing, plugging, and re-plugging oil and gas
wells. The District Manager shall be contacted if gas is being
produced.
(2) A diligent effort shall be made to clean the well to the
original total depth. The mine operator shall contact the District
Manager prior to stopping the operation to pull casing or clean out the
total depth of the well. If this depth cannot be reached, and the total
depth of the well is less than 4,000 feet, the operator shall
completely clean out the well from the surface to at least 200 feet
below the base of the lowest mineable coal seam, unless the District
Manager requires cleaning to a greater depth based on the geological
strata or pressure within the well. The operator shall provide the
District Manager with all information it possesses concerning the
geological nature of the strata and the pressure of the well. If the
total depth of the well is 4,000 feet, or greater, the operator shall
completely clean out the well from the surface to at least 400 feet
below the base of the lowest mineable coal seam. The operator shall
remove all material from the entire diameter of the well, wall to wall.
If the total depth of the well is unknown and there is no historical
information, the mine operator must contact the District Manager before
proceeding.
(3) The operator shall prepare down-hole logs for each well. Logs
shall consist of a caliper survey, a gamma log, a bond log and a
deviation survey for determining the top, bottom, and thickness of all
coal seams down to the lowest minable coal seam, potential hydrocarbon
producing strata and the location of any existing bridge plug. In
addition, a journal shall be maintained describing the depth of each
material encountered; the nature of each material encountered; bit size
and type used to drill each portion of the hole; length and type of
each material used to plug the well; length of casing(s) removed,
perforated or ripped or left in place; any section where casing was cut
or milled; and other pertinent information concerning cleaning and
sealing the well. Invoices, workorders, and other records relating to
all work on the well shall be maintained as part of the logs and
provided to MSHA upon request.
(4) When cleaning out the well as detailed in subparagraph (f)(2),
the operator shall make a diligent effort to remove all of the casing
in the well. After the well is completely cleaned out and all the
casing removed, the well should be plugged to the total depth by
pumping expanding cement slurry and pressurizing to at least 200 pounds
per square inch (psi). If the casing cannot be removed, it must be cut,
milled, perforated or ripped at all mineable coal seam levels to
facilitate the removal of any remaining casing in the coal seam by the
mining equipment. Any casing which remains shall be perforated or
ripped to permit the injection of cement into voids within and around
the well. All casing remaining at mineable coal seam levels shall be
perforated or ripped at least every 5 feet from 10 feet below the coal
seam to 10 feet above the coal seam.
(5) Perforations or rips are required at least every 50 feet from
200 feet (400 feet if the total well depth is 4,000 feet or greater)
below the base of the lowest mineable coal seam up to 100 feet above
the uppermost mineable coal seam. The mine operator shall take
appropriate steps to ensure that the annulus between the casing and the
well walls are filled with expanding (minimum 0.5 percent expansion
upon setting) cement and contain no voids.
(6) If it is not possible to remove all of the casing, the operator
shall notify the District Manager before any other work is performed.
If the well cannot be cleaned out or the casing removed, the operator
shall prepare the well as described from the surface to at least 200
feet below the base of the lowest mineable coal seam for wells less
than 4,000 feet in depth and 400 feet below the lowest mineable coal
seam for wells 4,000 feet or greater, unless the District Manager
requires cleaning out and removal of casing to a greater depth based on
geological strata or the pressure within the well.
(7) If the operator, using a casing bond log, can demonstrate to
the satisfaction of the District Manager that all annuli in the well
are already adequately sealed with cement, the operator will not be
required to perforate or rip the casing for that particular well. When
multiple casing and tubing strings are present in the coal horizon(s),
any remaining casing shall be ripped or perforated; then it shall be
filled with expanding cement as indicated above. An acceptable casing
bond log for each casing and tubing string is needed if used in lieu of
ripping or perforating multiple strings.
(8) If the District Manager concludes that the completely cleaned
out well is emitting excessive amounts of gas, the operator must place
a mechanical bridge plug in the well. It must be placed in a competent
stratum at least 200 feet (400 feet if the total well depth is 4,000
feet or greater) below the base of the lowest mineable coal seam, but
above the top of the uppermost hydrocarbon-producing stratum, unless
the District Manager requires a greater distance based on geological
strata the pressure within the well. The operator shall provide the
District Manager with all information it possesses concerning the
geological nature of the strata and the pressure of the well. If it is
not possible to set a mechanical bridge plug, an appropriately sized
packer shall be used. The mine operator shall document what has been
done to ``kill the well'' and plug the carbon producing strata.
(9) If the upper-most hydrocarbon-producing stratum is within 300
feet of the base of the lowest minable coal seam, the operator shall
properly place mechanical bridge plugs as described in subparagraph
(f)(8) to isolate the hydrocarbon- producing stratum from the expanding
cement plug. The operator shall place a minimum of 200 feet (400 feet
if the total well depth is 4,000 feet or greater) of expanding cement
below the lowest mineable coal seam, unless the District Manager
requires a greater distance based on the geological strata or the
pressure within the well.
(g) The following procedures shall be followed for plugging or re-
plugging oil or gas wells to the surface after completely cleaning out
the well as previously specified:
(1) The operator shall pump expanding cement slurry down the well
to form a plug which runs from at least 200 feet (400 feet if the total
well depth is 4,000 feet or greater) below the base of the lowest
mineable coal seam (or lower if required by the District Manager based
on the geological strata or the pressure within the well) to the
[[Page 81570]]
surface. The expanding cement shall be placed in the well under a
pressure of at least 200 psi.
(2) Portland cement or a lightweight cement mixture shall be used
to fill the area from 100 feet above the top of the uppermost mineable
coal seam (or higher if required by the District Manager that a higher
distance is required due to the geological strata or the pressure
within the well) to the surface.
(3) The operator shall embed steel turnings or other small magnetic
particles in the top of the cement near the surface to serve as a
permanent magnetic monument of the well. In the alternative, a 4-inch
or larger diameter casing, set in cement, shall extend at least 36
inches above the ground level with the American Petroleum Institute
(API) well number engraved or welded on the casing. When the hole
cannot be marked with a physical monument (e.g., prime farmland), high-
resolution GPS coordinates (one-half meter resolution) shall be
required.
(h) The following procedures shall be followed for plugging or re-
plugging oil and gas wells for use as degasification wells after
completely cleaning out the well as previously specified:
(1) The operator shall set a cement plug in the well by pumping an
expanding cement slurry down the tubing to provide at least 200 feet
(400 feet if the total well depth is 4,000 feet or greater) of
expanding cement below the lowest mineable coal seam, unless the
District Manager requires a greater depth based on the geological
strata or the pressure within the well. The expanding cement shall be
placed in the well under a pressure of at least 200 psi. The top of the
expanding cement shall extend at least 50 feet above the top of the
coal seam being mined, unless the District Manager requires a greater
distance based on the geological strata or the pressure within the
well.
(2) The operator shall securely grout into the bedrock of the upper
portion of the degasification well a suitable casing to protect it. The
remainder of this well may be cased or uncased.
(3) The operator shall fit the top of the degasification casing
with a wellhead equipped as required by the District Manager in the
approved ventilation plan. Such equipment may include check valves,
shut-in valves, sampling ports, flame arrestor equipment, and security
fencing.
(4) Operation of the degasification well shall be addressed in the
approved ventilation plan. This may include periodic tests of methane
levels and limits on the minimum methane concentrations that may be
extracted.
(5) After the area of the coal mine that is degassed by a well is
sealed or the coal mine is abandoned, the operator must plug all
degasification wells using the following procedures:
(i) The operator shall insert a tube to the bottom of the well or,
if not possible, to within 100 feet above the coal seam being mined.
Any blockage must be removed to ensure that the tube can be inserted to
this depth.
(ii) The operator shall set a cement plug in the well by pumping
Portland cement or a lightweight cement mixture down the tubing until
the well is filled to the surface.
(iii) The operator shall embed steel turnings or other small
magnetic particles in the top of the cement near the surface to serve
as a permanent magnetic monument of the well. In the alternative, a 4-
inch or larger casing, set in cement, shall extend at least 36 inches
above the ground level with the API well number engraved or welded on
the casing.
(i) The following provisions apply to all wells which the operator
determines, and with which the MSHA District Manager agrees, cannot be
completely cleaned out due to damage to the well caused by subsidence,
caving, or other factors.
(1) The operator shall drill a hole adjacent and parallel to the
well, to a depth of at least 200 feet (400 feet if the total well depth
is 4,000 feet or greater) below the lowest mineable coal seam, unless
the District Manager requires a greater depth based on the geological
strata or the pressure within the well.
(2) The operator shall use a geophysical sensing device to locate
any casing which may remain in the well.
(3) If the well contains casing(s), the operator shall drill into
the well from the parallel hole. From 10 feet below the coal seam to 10
feet above the coal seam, the operator shall perforate or rip all
casings at least every 5 feet. Beyond this distance, the operator shall
perforate or rip at least every 50 feet from at least 200 feet (400
feet if the total well depth is 4,000 feet or greater) below the base
of the lowest mineable coal seam up to 100 feet above the seam being
mined, unless the District Manager requires a greater distance based on
the geological strata or the pressure within the well. The operator
shall fill the annulus between the casings and between the casings and
the well wall with expanding (minimum 0.5 percent expansion upon
setting) cement and shall ensure that these areas contain no voids. If
the operator, using a casing bond log, can demonstrate to the
satisfaction of the District Manager that the annulus of the well is
adequately sealed with cement, then the operator shall not be required
to perforate or rip the casing for that particular well or fill these
areas with cement. When multiple casing and tubing strings are present
in the coal horizon(s), any casing which remains shall be ripped or
perforated and filled with expanding cement as indicated. An acceptable
casing bond log for each casing and tubing string shall be made if this
used in lieu of ripping or perforating multiple strings.
(4) Where the operator determines, and the District Manager agrees,
that there is insufficient casing in the well to allow the method
outlined to be used, then the operator shall use a horizontal hydraulic
fracturing technique to intercept the original well. From at least 200
feet (400 feet if the total well depth is 4,000 feet or greater) below
the base of the lowest mineable coal seam to a point at least 50 feet
above the seam being mined, the operator shall fracture in at least six
places at intervals to be agreed upon by the operator and the District
Manager after considering the geological strata and the pressure within
the well. The operator shall pump expanding cement into the fractured
well in sufficient quantities and in a manner which fills all
intercepted voids.
(5) The operator shall prepare down-hole logs for each well. Logs
shall consist of a caliper survey, a gamma log, a bond log and a
deviation survey for determining the top, bottom, and thickness of all
coal seams down to the lowest minable coal seam, potential hydrocarbon
producing strata and the location of any existing bridge plug. The
operator may obtain the logs from the adjacent hole rather than the
well if the condition of the well makes it impractical to insert the
equipment necessary to obtain the log.
(6) A journal shall be maintained that describes: the depth of each
material encountered; the nature of each material encountered; bit size
and type used to drill each portion of the hole; length and type of
each material used to plug the well; length of casing(s) removed,
perforated or ripped or left in place; any sections where casing was
cut or milled; and other pertinent information concerning sealing the
well. Invoices, workorders, and other records relating to all work on
the well shall be maintained as part of this journal and provided to
MSHA upon request.
(7) After the operator has plugged the well, the operator shall
plug the adjacent hole, from the bottom to the surface, with Portland
cement or a lightweight cement mixture. The operator shall embed steel
turnings or other small magnetic particles in the top
[[Page 81571]]
of the cement near the surface to serve as a permanent magnetic
monument of the well. In the alternative, a 4-inch or larger casing,
set in cement, shall extend at least 36 inches above the ground level.
A combination of the methods outlined previously may have to be used in
a single well, depending upon the conditions of the hole and the
presence of casings. The operator and the District Manager shall
discuss the nature of each hole and if the District Manager requires
more than one method be utilized. The mine operator may submit an
alternative plan to the District Manager for approval to use different
methods including certification by a registered petroleum engineer to
support the proposed alternative methods to address wells that cannot
be completely cleaned out.
(j) The following procedures shall be followed when mining within a
100-feet diameter barrier around a well.
(1) A representative of the operator, a representative of the
miners, the appropriate State agency, or the MSHA District Manager may
request that a conference be conducted prior to intersecting any
plugged or re-plugged well. The party requesting the conference shall
notify all other parties listed above within a reasonable time prior to
the conference to provide opportunity for participation. The purpose of
the conference shall be to review, evaluate, and accommodate any
abnormal or unusual circumstance related to the condition of the well
or surrounding strata when such conditions are encountered.
(2) The operator shall intersect a well on a shift approved by the
District Manager. The operator shall notify the District Manager and
the miners' representative in sufficient time prior to intersecting a
well to provide an opportunity to have representatives present.
(3) When using continuous mining methods, the operator shall
install drivage sights at the last open crosscut near the place to be
mined to ensure intersection of the well. The drivage sites shall not
be more than 50 feet from the well. When using longwall mining methods,
distance markers shall be installed on 5-foot centers for a distance of
50 feet in advance of the well in the headgate entry and in the
tailgate entry.
(4) The operator shall ensure that fire-fighting equipment
including fire extinguishers, rock dust, and sufficient fire hose to
reach the working face area of the well intersection (when either the
conventional or continuous mining method is used) is available and
operable during all well intersections. The fire hose shall be located
in the last open crosscut of the entry or room. The operator shall
maintain the water line to the belt conveyor tailpiece along with a
sufficient amount of fire hose to reach the farthest point of
penetration on the section. When the longwall mining method is used, a
hose to the longwall water supply is sufficient.
(5) The operator shall ensure that sufficient supplies of roof
support and ventilation materials shall be available and located at the
last open crosscut. In addition, emergency plugs and suitable sealing
materials shall be available in the immediate area of the well
intersection.
(6) On the shift prior to intersecting the well, the operator shall
service all equipment and check it for permissibility. Water sprays,
water pressures, and water flow rates used for dust and spark
suppression shall be examined and any deficiencies corrected.
(7) The operator shall calibrate the methane monitor(s) on the
longwall, continuous mining machine, or cutting machine and loading
machine on the shift prior to intersecting the well.
(8) When mining is in progress, the operator shall perform tests
for methane with a handheld methane detector at least every 10 minutes
from the time that mining with the continuous mining machine or
longwall face is within 30 feet of the well until the well is
intersected. During the actual cutting process, no individual shall be
allowed on the return side until the well intersection has been
completed and the area has been examined and declared safe. All
workplace examinations on the return side of the shearer shall be
conducted while the shearer is idle. The operator's most current
approved ventilation plan shall be followed at all times unless the
District Manager requires a greater air velocity for the intersect.
(9) When using continuous or conventional mining methods, the
working place shall be free from accumulations of coal dust and coal
spillages, and rock dust shall be placed on the roof, rib, and floor to
within 20 feet of the face when intersecting the well. On longwall
sections, rock dusting shall be conducted and placed on the roof, rib,
and floor up to both the headgate and tailgate gob.
(10) When the well is intersected, the operator shall de-energize
all equipment, and thoroughly examine and determine the area to be safe
before permitting mining to resume.
(11) After a well has been intersected and the working place
determined to be safe, mining shall continue inby the well a sufficient
distance to permit adequate ventilation around the area of the well.
(12) When necessary, torches shall be used for inadequately or
inaccurately cut or milled casings. No open flame shall be permitted in
the area until adequate ventilation has been established around the
well bore and methane levels of less than 1.0 percent are present in
all areas that will be exposed to flames and sparks from the torch. The
operator shall apply a thick layer of rock dust to the roof, face,
floor, ribs and any exposed coal within 20 feet of the casing prior to
the use of torches.
(13) Non-sparking (brass) tools shall be located on the working
section and shall be used exclusively to expose and examine cased
wells.
(14) No person shall be permitted in the area of the well
intersection except those engaged in the operation, company personnel,
representatives of the miners, personnel from MSHA, and personnel from
the appropriate State agency.
(15) The operator shall alert all personnel in the mine to the
planned intersection of the well prior to their going underground if
the planned intersection is to occur during their shift. This warning
shall be repeated for all shifts until the well has been mined through.
(16) The well intersection shall be under the direct supervision of
a certified individual. Instructions concerning the well intersection
shall be issued only by the certified individual in charge.
(17) If the mine operator cannot find the well in the middle of the
panel or a gate section misses the anticipated intersection, mining
shall cease and the District Manager shall be notified.
(18) A copy of the PDO granted by MSHA shall be maintained at the
mine and be available to the miners.
(19) If the well is not plugged to the total depth of all minable
coal seams identified in the core hole logs, any coal seams beneath the
lowest plug shall remain subject to the barrier requirements of 30 CFR
75.1700.
(20) All necessary safety precautions and safe practices required
by MSHA regulations and State regulatory agencies having jurisdiction
over the plugging site shall be followed.
(21) All miners involved in the plugging or re-plugging operations
shall be trained on the contents of the PDO granted by MSHA prior to
starting the process.
(22) Mechanical bridge plugs should incorporate the best available
technologies required or recognized by the State regulatory agency and/
or oil and gas industry.
[[Page 81572]]
(23) Within 30 days after the PDO granted by MSHA becomes final,
the operator shall submit proposed revisions for its approved 30 CFR
part 48 training plan to the District Manager. These proposed revisions
shall include initial and refresher training on compliance with the
terms and conditions stated in the PDO granted by MSHA. The operator
shall provide all miners involved in well intersection with training on
the requirements of the PDO granted by MSHA prior to mining within 150
feet of a well intended to be mined through.
(24) The responsible person required under 30 CFR 75.1501 shall be
responsible for well intersection emergencies. The well intersection
procedures shall be reviewed by the responsible person prior to any
planned intersection.
(25) Within 30 days after the PDO granted by MSHA becomes final,
the operator shall submit proposed revisions for its approved mine
emergency evacuation and firefighting program of instruction required
under 30 CFR 75.1502. The operator shall revise the program of
instruction to include the hazards and evacuation procedures to be used
for well intersections. All underground miners shall be trained in this
revised plan within 30 days of submittal.
(k) The miners at the Eagle #3 mine are not represented by a labor
union and do not have a miner's representative. The petition is posted
at the mine.
In support of the proposed alternative method, the petitioner has
also submitted: mine maps indicating well locations, current mining in
the area and projected mining inby the gas wells; well production
records and charts; schematics showing general cross-sections of casing
and tubing; and other relevant facts.
The petitioner asserts that the alternative method proposed will at
all times guarantee no less than the same measure of protection
afforded the miners under the mandatory standard.
