(3) 70 percent of the minimum phaseto-phase short-circuit current available
at the end of the trailing cable.
(d) The calibrated trip setting of the
circuit breakers will be sealed, locked,
or protected so that the setting cannot be
changed.
(e) The circuit breakers will have
permanent, legible labels indicating the
circuit, cable size, maximum cable
length, and the maximum instantaneous
trip unit setting. If the trailing cable
sizes are intermixed at a section power
center, the plugs will be constructed or
designed, for example, keyed or sized,
to permit only the proper type and
length of cable to be plugged into the
receptacle with the proper settings.
(f) Replacement instantaneous trip
units used to protect trailing cables
affected by this petition will be
calibrated and set in accordance with
alternative method item (c). This setting
will be sealed, locked, or protected.
(g) All components providing shortcircuit protection will have a sufficient
interruption rating in accordance with
the maximum calculated fault currents
available.
(h) Any trailing cable not in safe
operating condition will be removed
from service immediately and repaired
or replaced.
(i) If the mining methods or operating
procedures cause or contribute to
trailing cable damage, the cable will be
removed from service immediately and
repaired or replaced. Additional
precautions will be taken to ensure that,
in the future, the cable is protected and
maintained in safe operating condition.
(j) Each trailing cable splice or repair
will be made in a workmanlike manner
and in accordance with the instructions
of the manufacturer of the splice or
repair kit. The outer jacket of each
splice will be vulcanized with flame
resistant material or made with material
that has been approved by MSHA as
flame resistant. Splices will comply
with the requirements of 30 CFR 75.603
and 75.604.
(k) At the beginning of each
production shift, persons designated by
the mine operator will visually examine
trailing cables to ensure that they are in
safe operating condition. The
instantaneous trip unit settings of the
specially calibrated circuit breakers will
also be visually examined to ensure that
the seals or locks have not been
removed and that they are set in
accordance with alternative method
item (c).
(l) Permanent warning labels will be
installed and maintained on the cover(s)
of the power center or distribution box
identifying the location of each sealed
short-circuit protection device. The

labels will warn miners not to change or
alter the sealed short-circuit settings.
(m) This petition will apply to the
initial bottom development of the mine,
working sections that mine around gas
wells, and working sections developing
mains, submains, three entry panels,
and bleeder and recovery entries.
(n) This petition will not be
implemented until miners designated to
examine the integrity of the seals or
locks, to verify the short-circuit settings,
and to examine trailing cables for
defects and damage have received
training.
(o) Within 60 days after the Proposed
Decision and Order (PDO) becomes
final, the petitioner will submit
proposed revisions for its approved part
48 training plan to the District Manager.
The proposed revisions will include
initial and refresher training regarding
compliance with the terms and
conditions of the PDO.
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.

Regulation Affected: 30 CFR 75.1700
Oil and Gas Wells.
Modification Request: The petitioner
requests a modification of the existing
standard, 30 CFR 75.1700, as it relates
to oil and gas wells at the mine.
Specifically, the petitioner is proposing:
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
mandatory procedures after approval
has been granted to mine through a
plugged or re-plugged well.
The petitioner states:
(a) District Manager Approval
Required:
(1) The type of oil or gas well subject
to this petition includes wells that have
been depleted of oil or gas production,
wells that have not produced oil or gas
and may have been plugged, and active
wells. Marcellus and Utica wells may
not be mined through. No Marcellus or
Utica wells are contained within the
petition mine permits and are not
subject to this modification.
(2) 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, or previously
plugged wells, water injection wells,
and carbon dioxide sequestration wells)
until the District Manager has given
approval to proceed with mining. Wells
drilled into potential oil or gas
producing formations that did not
produce commercial quantities of either
gas or oil (exploratory wells, wildcat
wells or dry holes) are classified as oil
or gas wells by MSHA. If the District
Manager determines that the procedures
have been complied with as described
in subparagraphs 2(a) and (b), he will
provide his approval, and the mine
VerDate Sep<11>2014
18:24 Mar 21, 2022
Jkt 256001
operator may then mine within the
safety barrier of the well, subject to the
terms of this Order. If well intersection
is not planned, the mine operator may
request a permit to reduce the 300-foot
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. This information
may include survey closure data, downhole well deviation logs, historical well
intersection location data and any
additional data required by the District
Manager. If the District Manager
determines that the proposed barrier
reduction is reasonable, he will provide
his approval, and the mine operator may
then mine within the safety barrier of
the well.
(3) Prior to mining within the 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 with appropriate
authority 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 this order.
(4) The affidavit or declaration must
be accompanied by all logs described in
(b)(8) and (b)(9) and any other records,
described in those subparagraphs, the
District Manager may request. The
District Manager will review the
affidavit or declaration, the logs and any
other records provided, and may inspect
the well itself, and will then determine
if the operator has complied with the
procedures for cleaning out, preparing,
and plugging each well as described by
the terms and conditions of this Order.
(5) The terms and conditions of this
petition apply to all types of
underground coal mining.
(b) The petitioner proposes to use the
following mandatory procedures for
cleaning out and preparing vertical oil
and gas wells prior to plugging or replugging.
(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.
(3) If the total depth of the well is less
than 4,000 feet and the total depth
cannot be reached, the operator shall
PO 00000
Frm 00074
Fmt 4703
Sfmt 4703

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 his
judgment as to what is required due to
the geological strata, or due to the
pressure within the well.
(4) 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.
(5) 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
to provide a higher degree of protection
for miners, in light of the greater
pressure on wells of greater depth. The
operator shall remove all material from
the entire diameter of the well, wall to
wall.
(6) 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.
(7) 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. 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
sections where casing was cut or milled;
and other pertinent information
concerning cleaning and sealing the
well. Invoices, work-orders, and other
records relating to all work on the well
shall be maintained as part of this
journal and provided to MSHA upon
request.
(8) When cleaning out the well as
provided for in (b)(2), the operator shall
make a diligent effort to remove all of
the casing from 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

lotter on DSK11XQN23PROD with NOTICES1
16236
Federal Register / Vol. 87, No. 55 / Tuesday, March 22, 2022 / Notices
which remains shall be perforated or
ripped to permit the injection of cement
into voids within and around the well.
(9) 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. 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 must take
appropriate steps to ensure that the
annulus between the casing and the
well walls are filled with expanding
(minimum 0.5% expansion upon
setting) cement and contain no voids.
(10) 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 cannot be
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 in consideration of
geological strata, or due to the pressure
within the well.
(11) 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, then 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 casing that remains
shall be ripped or perforated and 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.
(12) 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 his judgment that it is required
due to the geological strata, or due to the
pressure within the well. The operator
shall provide the District Manager with
all information the operator possesses
VerDate Sep<11>2014
18:24 Mar 21, 2022
Jkt 256001
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 may be used. The mine operator
shall document what has been done to
‘‘kill the well’’ and plug the carbon
producing strata.
(13) 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
(b)(11) to isolate the hydrocarbonproducing stratum from the expanding
cement plug. Nevertheless, the operator
shall place a minimum of 200 vertical
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 his
judgment that it is required due to the
geological strata, or due to the pressure
within the well.
(c) Mandatory Procedures for Plugging
or Re-Plugging Oil or Gas Wells to the
Surface. After completely cleaning out
the well as specified in (b), the
following procedures shall be used to
plug or re-plug wells:
(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 his judgment that a
lower depth is required due to the
geological strata, or due to the pressure
within the well) to the surface. The
expanding cement will be placed in the
well under a pressure of at least 200 psi.
Portland cement or a lightweight cement
mixture may 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 based on his judgment that a
higher distance is required due to the
geological strata, or due to the pressure
within the well) to the surface.
(2) 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)
are required.

(d) The petitioner proposes to use the
following mandatory procedures for
plugging or re-plugging oil and gas wells
for use as degasification wells. After
completely cleaning out the well as
specified in (b), the following
procedures shall be utilized when
plugging or re-plugging wells that are to
be used as degasification wells:
(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 his judgment that a
greater depth is required due to the
geological strata, or due to the pressure
within the well.
(i) The expanding cement will be
placed in the well under a pressure of
at least 200 psi.
(ii) 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 due to the geological strata, or
due to 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
in order 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.
(e) The petitioner proposes to use the
following mandatory alternative
procedures for preparing and plugging
or re-plugging oil or gas wells. 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.
(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 distance due to the geological
strata, or due to 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 his judgment that a greater
distance is required due to the
geological strata, or due to 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%
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
will 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
remain, shall be ripped or perforated
and 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.
(4) Where the operator determines,
and the District Manager agrees, that
there is insufficient casing in the well to
VerDate Sep<11>2014
18:24 Mar 21, 2022
Jkt 256001
allow use of the method outlined in
subparagraph (e)(3), 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 agreed upon by the
operator and the District Manager after
considering the geological strata and the
pressure within the well. The operator
shall then 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
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
sections where casing was cut or milled;
other pertinent information concerning
sealing the well. Invoices, work orders,
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 as described in (e)(3) and/or (e)(4),
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 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 in (e)(3) and (e)(4) 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. The District
Manager may require that more than one
method be utilized. The mine operator
PO 00000

may submit an alternative plan to the
District Manager for approval to use
different methods to address wells that
cannot be completely cleaned out. The
District Manager may require additional
documentation and certification by a
registered petroleum engineer to
support the proposed alternative
methods.
(f) The petitioner proposes to use the
following mandatory when mining
within a 100-foot 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. Upon receipt of any such request,
the District Manager shall schedule such
a conference. 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 in order 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.
(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
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.
(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) Within 12 hours 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 within 12
hours 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 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. The
operator’s most current Approved
Ventilation Plan will be followed at all
times unless the District Manager deems
a greater air velocity for the intersect is
necessary.
(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. When the well is intersected, the
operator shall deenergize all equipment,
and thoroughly examine and determine
the area to be safe before permitting
mining to resume.
(10) 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.
(11) If the casing is cut or milled at
the coal seam level, the use of torches
should not be necessary. However, in
rare instances, torches may 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% 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.
(12) Non-sparking (brass) tools will be
located on the working section and will
VerDate Sep<11>2014

Jkt 256001
be used exclusively to expose and
examine cased wells.
(13) No person shall be permitted in
the area of the well intersection except
those actually engaged in the operation,
including company personnel,
representatives of the miners, personnel
from MSHA, and personnel from the
appropriate State agency.
(14) 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.
(15) The well intersection shall be
under the direct supervision of a
responsible person. Instructions
concerning the well intersection shall be
issued only by the certified individual
in charge.
(16) If the mine operator cannot find
the well in the middle of the panel or
room and misses the anticipated
intersection, mining shall cease and the
District Manager shall be notified.
(17) The provisions of this Decision
and Order do not impair the authority
of representatives of MSHA to interrupt
or halt the well intersection, and to
issue a withdrawal order, when they
deem it necessary for the safety of the
miners. MSHA may order an
interruption or cessation of the well
intersection and/or a withdrawal of
personnel by issuing either a verbal or
written order to that effect to a
representative of the operator, which
order shall include the basis for the
order. Operations in the affected area of
the mine may not resume until a
representative of MSHA permits
resumption. The mine operator and
miners shall comply with verbal or
written MSHA orders immediately. All
verbal orders shall be committed to
writing within a reasonable time as
conditions permit.
(18) A copy of this Petition 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 will
remain subject to the barrier
requirements of 30 CFR 75.1700, should
those coal seams be developed in the
future.
(20) All necessary safety precautions
and safe practices required by MSHA
regulation and by State agencies that
have jurisdiction over the plugging site
still apply and shall be followed to
provide the upmost protection to the
miners involved in the process.

(21) All miners involved in the
plugging or re-plugging operation will
be trained on the contents of this
petition prior to starting the process and
a copy of this petition will be posted at
the well site until the plugging or replugging has been completed.
(22) Mechanical bridge plugs should
incorporate the best available
technologies that are either required or
recognized by the State regulatory
agency and/or oil and gas industry.
(23) Within 30 days after this Decision
and Order 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
Decision and Order. The operator shall
provide all miners involved in well
intersection with training on the
requirements of this Decision and Order
prior to mining within 150 feet of the
next well intended to be mined through.
(24) The responsible person required
under 30 CFR 75.1501 Emergency
Evacuations, is responsible for well
intersection emergencies. The well
intersection procedures should be
reviewed by the responsible person
prior to any planned intersection.
(25) Within 30 days after this Decision
and Order 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 will revise the program of
instruction to include the hazards and
evacuation procedures to be used for
well intersections. All underground
miners will be trained in this revised
plan within 30 days of submittal. The
procedure as specified in 30 CFR 48.3
for approval of proposed revisions to
already approved training plans shall
apply.
The petitioner asserts that the
alternate method proposed will at all
times guarantee no less than the same
measure of protection afforded the
miners under the applicable standard.

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 (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, Sec. Sec. 44.10 and 44.11 of 30 CFR establish the
requirements for filing petitions for modification.

Regulation Affected: 30 CFR 75.1700 Oil and Gas Wells.
Modification Request: The petitioner requests a modification of the
existing standard, 30 CFR 75.1700, as it relates to oil and gas wells
at the mine. Specifically, the petitioner is proposing: 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 mandatory
procedures after approval has been granted to mine through a plugged or
re-plugged well.
The petitioner states:
(a) District Manager Approval Required:
(1) The type of oil or gas well subject to this petition includes
wells that have been depleted of oil or gas production, wells that have
not produced oil or gas and may have been plugged, and active wells.
Marcellus and Utica wells may not be mined through. No Marcellus or
Utica wells are contained within the petition mine permits and are not
subject to this modification.
(2) 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, or
previously plugged wells, water injection wells, and carbon dioxide
sequestration wells) until the District Manager has given approval to
proceed with mining. Wells drilled into potential oil or gas producing
formations that did not produce commercial quantities of either gas or
oil (exploratory wells, wildcat wells or dry holes) are classified as
oil or gas wells by MSHA. If the District Manager determines that the
procedures have been complied with as described in subparagraphs 2(a)
and (b), he will provide his approval, and the mine operator may then
mine within the safety barrier of the well, subject to the terms of
this Order. If well intersection is not planned, the mine operator may
request a permit to reduce the 300-foot 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. This information may include survey closure data, down-
hole well deviation logs, historical well intersection location data
and any additional data required by the District Manager. If the
District Manager determines that the proposed barrier reduction is
reasonable, he will provide his approval, and the mine operator may
then mine within the safety barrier of the well.
(3) Prior to mining within the 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 with appropriate authority 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
this order.
(4) The affidavit or declaration must be accompanied by all logs
described in (b)(8) and (b)(9) and any other records, described in
those subparagraphs, the District Manager may request. The District
Manager will review the affidavit or declaration, the logs and any
other records provided, and may inspect the well itself, and will then
determine if the operator has complied with the procedures for cleaning
out, preparing, and plugging each well as described by the terms and
conditions of this Order.
(5) The terms and conditions of this petition apply to all types of
underground coal mining.
(b) The petitioner proposes to use the following mandatory
procedures 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.
(3) If the total depth of the well is less than 4,000 feet and the
total depth cannot be reached, 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 his judgment as to what is
required due to the geological strata, or due to the pressure within
the well.
(4) 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.
(5) 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 to
provide a higher degree of protection for miners, in light of the
greater pressure on wells of greater depth. The operator shall remove
all material from the entire diameter of the well, wall to wall.
(6) 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.
(7) 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 sections where casing was
cut or milled; and other pertinent information concerning cleaning and
sealing the well. Invoices, work-orders, and other records relating to
all work on the well shall be maintained as part of this journal and
provided to MSHA upon request.
(8) When cleaning out the well as provided for in (b)(2), the
operator shall make a diligent effort to remove all of the casing from
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
[[Page 16236]]
which remains shall be perforated or ripped to permit the injection of
cement into voids within and around the well.
(9) 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. 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 must take appropriate steps to ensure that the annulus between
the casing and the well walls are filled with expanding (minimum 0.5%
expansion upon setting) cement and contain no voids.
(10) 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 cannot be
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 in consideration of geological strata, or due to the
pressure within the well.
(11) 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, then 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 casing that remains shall be ripped or perforated and
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.
(12) 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 his judgment
that it is required due to the geological strata, or due to the
pressure within the well. The operator shall provide the District
Manager with all information the operator 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 may be used. The mine operator shall document what has been done
to ``kill the well'' and plug the carbon producing strata.
(13) 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 (b)(11) to
isolate the hydrocarbon-producing stratum from the expanding cement
plug. Nevertheless, the operator shall place a minimum of 200 vertical
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 his judgment that
it is required due to the geological strata, or due to the pressure
within the well.
(c) Mandatory Procedures for Plugging or Re-Plugging Oil or Gas
Wells to the Surface. After completely cleaning out the well as
specified in (b), the following procedures shall be used to plug or re-
plug wells:
(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 his judgment that a lower depth is required due to the geological
strata, or due to the pressure within the well) to the surface. The
expanding cement will be placed in the well under a pressure of at
least 200 psi. Portland cement or a lightweight cement mixture may 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 based
on his judgment that a higher distance is required due to the
geological strata, or due to the pressure within the well) to the
surface.
(2) 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) are required.
(d) The petitioner proposes to use the following mandatory
procedures for plugging or re-plugging oil and gas wells for use as
degasification wells. After completely cleaning out the well as
specified in (b), the following procedures shall be utilized when
plugging or re-plugging wells that are to be used as degasification
wells:
(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 his judgment that a
greater depth is required due to the geological strata, or due to the
pressure within the well.
(i) The expanding cement will be placed in the well under a
pressure of at least 200 psi.
(ii) 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 due to the geological strata, or due to 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 in order 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
[[Page 16237]]
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.
(e) The petitioner proposes to use the following mandatory
alternative procedures for preparing and plugging or re-plugging oil or
gas wells. 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.
(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 distance due to the geological
strata, or due to 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
his judgment that a greater distance is required due to the geological
strata, or due to 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% 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 will 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 remain, shall be ripped or perforated and 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.
(4) Where the operator determines, and the District Manager agrees,
that there is insufficient casing in the well to allow use of the
method outlined in subparagraph (e)(3), 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 agreed upon by the
operator and the District Manager after considering the geological
strata and the pressure within the well. The operator shall then 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 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 sections where casing was
cut or milled; other pertinent information concerning sealing the well.
Invoices, work orders, 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 as described in (e)(3)
and/or (e)(4), 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 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 in (e)(3) and
(e)(4) 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. The
District Manager may require that more than one method be utilized. The
mine operator may submit an alternative plan to the District Manager
for approval to use different methods to address wells that cannot be
completely cleaned out. The District Manager may require additional
documentation and certification by a registered petroleum engineer to
support the proposed alternative methods.
(f) The petitioner proposes to use the following mandatory when
mining within a 100-foot 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. Upon receipt of any such request, the
District Manager shall schedule such a conference. 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 in order 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.
(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.
(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
[[Page 16238]]
the immediate area of the well intersection.
(6) Within 12 hours 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 within 12 hours 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 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. The operator's most current Approved
Ventilation Plan will be followed at all times unless the District
Manager deems a greater air velocity for the intersect is necessary.
(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. When the well is
intersected, the operator shall deenergize all equipment, and
thoroughly examine and determine the area to be safe before permitting
mining to resume.
(10) 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.
(11) If the casing is cut or milled at the coal seam level, the use
of torches should not be necessary. However, in rare instances, torches
may 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% 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.
(12) Non-sparking (brass) tools will be located on the working
section and will be used exclusively to expose and examine cased wells.
(13) No person shall be permitted in the area of the well
intersection except those actually engaged in the operation, including
company personnel, representatives of the miners, personnel from MSHA,
and personnel from the appropriate State agency.
(14) 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.
(15) The well intersection shall be under the direct supervision of
a responsible person. Instructions concerning the well intersection
shall be issued only by the certified individual in charge.
(16) If the mine operator cannot find the well in the middle of the
panel or room and misses the anticipated intersection, mining shall
cease and the District Manager shall be notified.
(17) The provisions of this Decision and Order do not impair the
authority of representatives of MSHA to interrupt or halt the well
intersection, and to issue a withdrawal order, when they deem it
necessary for the safety of the miners. MSHA may order an interruption
or cessation of the well intersection and/or a withdrawal of personnel
by issuing either a verbal or written order to that effect to a
representative of the operator, which order shall include the basis for
the order. Operations in the affected area of the mine may not resume
until a representative of MSHA permits resumption. The mine operator
and miners shall comply with verbal or written MSHA orders immediately.
All verbal orders shall be committed to writing within a reasonable
time as conditions permit.
(18) A copy of this Petition 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 will remain subject to the barrier requirements of 30 CFR
75.1700, should those coal seams be developed in the future.
(20) All necessary safety precautions and safe practices required
by MSHA regulation and by State agencies that have jurisdiction over
the plugging site still apply and shall be followed to provide the
upmost protection to the miners involved in the process.
(21) All miners involved in the plugging or re-plugging operation
will be trained on the contents of this petition prior to starting the
process and a copy of this petition will be posted at the well site
until the plugging or re-plugging has been completed.
(22) Mechanical bridge plugs should incorporate the best available
technologies that are either required or recognized by the State
regulatory agency and/or oil and gas industry.
(23) Within 30 days after this Decision and Order 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 Decision and Order. The operator
shall provide all miners involved in well intersection with training on
the requirements of this Decision and Order prior to mining within 150
feet of the next well intended to be mined through.
(24) The responsible person required under 30 CFR 75.1501 Emergency
Evacuations, is responsible for well intersection emergencies. The well
intersection procedures should be reviewed by the responsible person
prior to any planned intersection.
(25) Within 30 days after this Decision and Order 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 will revise the program of
instruction to include the hazards and evacuation procedures to be used
for well intersections. All underground miners will be trained in this
revised plan within 30 days of submittal. The procedure as specified in
30 CFR 48.3 for approval of proposed revisions to already approved
training plans shall apply.
The petitioner asserts that the alternate method proposed will at
all times guarantee no less than the same measure of protection
afforded the miners under the applicable standard.
