River View Coal LLC Petition for Modification
Henderson County Mine
Mine ID 15-02709 Docket No. M-2022-012-C
PROPOSED DECISION AND ORDER
Pursuant to Section 101 (c) of the Federal Mine Safety and Health Act of 1977 ("The Act"), 30
U.S.C. Section 811, and 30 CFR § 44.10, River View Coal LLC, hereby petitions for the modification of the application of mandatory safety standard 30 CFR § 75.1700, at its Henderson County Mine located in Union County, Kentucky, MSHA I.D. No. 15-02709, to permit an alternative method of compliance with the requirement for leaving barrier pillars around oil and gas wells. In support of its petition, River View Coal LLC states as follows:
§ 75.1700 Oil and gas wells.
Each operator of a coal mine shall take reasonable measures to locate oil and gas wells penetrating coalbeds or any underground area of a coal mine. When located, such operator shall establish and maintain barriers around such oil and gas wells in accordance with State laws and regulations, except that such barriers shall not be less than 300 feet in diameter, unless the Secretary or his authorized representative permits a lesser barrier consistent with the applicable State laws and regulations where such lesser barrier will be adequate to protect against hazards from such wells to the miners in such mine, or unless the Secretary or his authorized representative requires a greater barrier where the depth of the mine, other geologic conditions, or other factors warrant such a greater barrier.
River View Coal LLC seeks modification of 30 CFR § 75.1700 as it pertains to leaving barrier pillars around coal and gas wells. River View Coal LLC requests this modification in order to be able to mine through plugged and abandoned oil and gas wells in the mineable coalbeds in the coal reserve area. Mining around certain plugged and abandoned oil and gas wells would alter the mining projections for the life of the mine and not allow for the most efficient use of air available to the mine. In addition, such well avoidance would adversely impact escapeway routes if the barrier established by 30 C.F.R. §75.1700 were to remain in place. The Petitioner acknowledges that mining within the 300 feet barrier established by 30 C.F.R. § 75.1700 is a hazard; however, the Petitioner states that the alternative method provided will at all times guarantee no less than the same measure of protection afforded by the standard.
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, alternative procedures for preparing and plugging or re-plugging oil or gas wells, and procedures after approval has been granted to mine.
FINDINGS OF FACT AND CONCLUSIONS OF LAW
The Henderson County Mine is located in Union County, Kentucky. The Henderson County mine is opened into the Kentucky #11 coal seam through two shaft openings and one slope and has two mechanized mining units (MMUs). Coal is produced using a continuous mining machines and shuttle cars. The mine normally operates 2 production shifts per day, seven days per week and employs 31 miners. The mine produces an average of 1006 tons of raw coal per day. Coal is transported from the underground section to the surface coal handling facility via a series of underground and surface conveyor belts.
The working sections would be directly affected by this modification. Although the modification deals with procedures for the working section, all underground mine personnel would be affected by this modification.
The miners at the Henderson County Mine are not represented by a labor union; and do not have a miner's representative. Before beginning the investigation, a meeting was held with all the interested parties to discuss the scope of the investigation and how the investigation would be conducted. Miners were afforded the opportunity to participate in the meeting but declined to attend.
The River View Coal LLC area consists of approximately 10,000 acres located in Henderson/Union County, Kentucky. The area is situated east of the town of Corydon. Predominately located in the Poole USGS Quad. The method of coal mining to be employed at the Henderson County Mine is with a continuous miner, room, and pillar. No secondary mining (pillar extraction) will be conducted.
The mineable coal seams in the reserve area are:
Seam Average, Thickness, Average and Depth Kentucky #11, 4.5', and 280',
Kentucky #9, 5.0', and 400'
There is a worked out #9 seam mine below the #11 seam and the #9 seam has been previously mined directly adjacent (west) to the current River View Coal LLC area. These old works are assumed to be flooded; however, the inundation potential is zero as sufficient barrier pillars will be utilized. This #9 seam mine has previously mined around and mined through plugged wells under a previously approved petition.
Well/Reservoir Characteristics
There are approximately 300 documented wells within the boundary of the proposed mining area. The wells range in heritage from the early 1940's through to Present. The average depth of the wells is 2540 feet.
There are 6 main oil producing fields in the mining area, with principal production coming from these formations:
1. Waltersburg Sandstone 1,760' deep
2. Cypress Sandstone 2,240' deep
3. Renault Limestone 2,580' deep
4. McClosky Lime 2,620' deep
Sandstones in the area have an average porosity ranging from 15% to 16%. Limestone porosities are much more variable ranging from 10% to 23%. Permeability's also vary ranging from 100 mD in sandstones to 1000 mD in limestone zones. Predominately muddy water along with muddy brines are the fluids that were produced. No significant amount of (Hydrogen Sulphide) H2S has ever been present in the fluids in Western Kentucky. There are no unconsolidated formations, karstic formations, or lost circulations in the proposed mining area.
A typical completion record consists of drilling with rotary tools, completed with cable tools, and setting casing ranging from 4 ½" to 5 ½" on top of or through the pay zones.
A typical casing string involves setting approximately 50' of 8 5/8", occasionally up to 10" surface casing followed by production casing ranging from 4 ½" or 5 ½."
Typical plugging affidavit consists of the following:
• 1807 1400 40 Sx Cement
• 1400 600 Gel Water
• 600 3 60 Sx Cement
Abandoned wells are either plugged in a typical fashion or the casing is left in the ground below the crop line with a cement plug over the casing. On occasion where the well is plugged the surface and production casing is left in the ground.
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.
Although MSHA has granted modifications of this standard at different mines over the years, changing circumstances in oil and gas drilling technology and practices compels MSHA to reconsider the safest approach to mining around or through such wells. In recent years, changes in hydraulic fracturing (fracking) technology, marketplace and resource conditions have led to an increase in the number and depth of oil and gas wells, penetrating the Kentucky #9 and #11 coal seams. Since deeper wells are usually associated with higher well pressures, modifications of § 75.1700 must include appropriate measures to better protect miners. In addition to the risks associated with higher well pressures, MSHA must ensure that operators are preparing and plugging wells to adequate depths to maintain adequate safety for miners. This Proposed Decision and Order addresses these concerns as they affect the mines listed in this order.
There are several differences between the petitioner's proposal and the amended terms and conditions set forth by MSHA. The essential changes include:
1. No Marcellus or Utica wells are contained within the listed mine's permits, but due to the possibility of future unconventional wells impacting this mine I.D., conditions set forth by MSHA emphasize that unconventional shale oil and gas wells are not subject to this modification.
2. Conventional coal bed methane wells (vertically drilled in the same manner as conventional oil and gas wells) exist within the listed mine's permits.
3. Conditions set forth by MSHA include required procedures in the event an uncharted well is inadvertently mined into.
4. The mines listed in this order do not incorporate longwall mining techniques, but due to the possibility of this mining method applying to these mine's I.D.s in the future, several conditions set forth by MSHA specific to longwall mining are included in this Order.
5. The mines listed in this order currently uses a continuous miner, to extract coal from the active coal face. When a well intersect is planned and a continuous miner, is to be used to facilitate removal of any remaining casing(s) or tubing string(s), the casing(s) and tubing string(s) should be milled at the mineable coal seam.
The terms and conditions required by MSHA will prepare these wells for safe intersection by making a diligent effort to clean the wells to the original total depth, removing all casing and plugging to the total depth by pumping expanding cement slurry and pressurizing to at least 200 psi. If the total depth cannot be reached and casing cannot be removed, the alternative methods included in this proposed decision and order have proven safe and effective when properly implemented.
Therefore, the terms and conditions as amended by MSHA will at all times guarantee no less than the same measure of protection afforded the miners under 30 C.F.R. § 75.1700 for wells at least 2,000 to 4,000 feet or greater in depth. On the basis of the petition, and the findings of MSHA's investigation, Henderson County Mine is granted a modification of the application of 30
C.F.R. § 75.1700 to its mines listed in this order.
ORDER
Under the authority delegated by the Secretary of Labor to the Administrator for Mine Safety and Health Enforcement, and under§ l0l(c) of the Federal Mine Safety and Health Act of 1977, 30
U.S.C. § 81l(c), and 30 C.F.R. Part 44, a modification of the application of30 C.F.R. § 75.1700 at Mine ID 15-02709, River View Coal LLC, Henderson County Mine is hereby:
GRANTED, subject to the following terms and conditions:
1. DISTRICT MANAGER APPROVAL REQUIRED
a. The type of oil or gas well that will be considered under this Petition includes abandoned wells that have been depleted of oil or gas production or have not produced oil or gas and may have been plugged, and active conventional vertical wells. Unconventional wells in the Marcellus, Utica, and all other unconventional shale oil and gas wells are not subject to this modification. Additionally, surface directional drilled (SDD) 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.
b. 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. Wells that were 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.
c. 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 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.
The affidavit or declaration must be accompanied by all logs described in subparagraphs 2(a)(2) and 2(a)(3) below and any other records described in those subparagraphs which the District Manager may request. The District Manager will review the affidavit or declaration, the logs and any other records that have been requested, 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. In addition, a site specific plan detailing procedures when mining within a 150 feet diameter of a well and when a well intersect is planned shall be submitted to the District Manager for approval prior to mining within 50 feet of a well, with or without actual well intersect. If the District Manager determines that the procedures have been complied with, the District Manager will approve, 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 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 in 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, the District Manager will approve, and 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 this Order apply to all types of underground coal mining.
2. MANDATORY PROCEDURES FOR CLEANING OUT, PREPARING, PLUGGING, AND RE-PLUGGING OIL OR GAS WELLS
a. MANDATORY PROCEDURES FOR CLEANING OUT AND PREPARING VERTICAL OIL AND GAS WELLS PRIOR TO PLUGGING OR RE- PLUGGING
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 immediately contacted by phone if gas is being produced and notified in writing.
(1) 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 Disrtrict Manager's judgment as to what 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 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.
Wells of this greater depth are under greater pressure, so the 400 feet requirement provides greater protection for miners. 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.
(2) 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.
(3) When cleaning out the well as provided for in subparagraph (a)(l), 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 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.
The mines subject to this order currently use a continuous miner to extract coal from the active coal face. When a well intersect is planned and a continuous miner is to be used to facilitate removal of remaining casing(s) or tubing string(s), the casing(s) and tubing string(s) should be milled at the mineable 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. See Appendix A. 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.
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 4000 feet in depth and 400 feet below the lowest mineable coal seam for wells 4000 feet or greater, unless the District Manager requires cleaning out and removal of casing to a greater depth based on the District Manager's judgement as to what is required due to geological strata, or due to the pressure within the well.
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 which 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.
(4) 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 the District Manager's 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 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 may be used.
The mine operator shall document what has been done to "kill the well" and plug the carbon producing strata.
(5) 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 (a)(4) to isolate the hydrocarbon-producing stratum from the expanding cement plug. Nevertheless, 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 District Manager's judgment that it is required due to the geological strata, or due to the pressure within the well.
b. MANDATORY PROCEDURES FOR PLUGGING OR RE-PLUGGING OIL OR GAS WELLS TO THE SURFACE
After completely cleaning out the well as specified in paragraph 2(a) above, 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 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 pounds per square inch.
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 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 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.
c. 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 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 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 is required due to the geological strata, or due to the pressure within the well. The diagram shown in Appendix A is representative of the locations of the perforations or ripping that must be done. 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 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.
(4) Where the operator determines, and the District Manager agrees, that there is insufficient casing in the well to allow the method outlined in subparagraph (c)(3) 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 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; and 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 subparagraphs (c)(3) and/or (c)(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 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 in subparagraphs (c)(3) and (c)(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.
3. MANDATORY PROCEDURES WHEN MINING WITHIN A 100-FEET DIAMETER BARRIER AROUND WELL
a. 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.
b. 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 48 hours in advance of a planned well intersect in order to provide an opportunity to have representatives present.
c. 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 location at the coal seam level, as determined from the well deviation survey. When using longwall mining methods, distance markers shall be installed on 5 feet centers for a distance of 50 feet in advance of the well in the headgate entry and in the tailgate entry.
d. 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. The belt conveyor tailpiece shall be defined as the location where the low belt tailpiece is connected to the low belt structure that the continuous haulage system rides on. When the longwall mining method is used, a hose to the longwall water supply is sufficient.
e. The operator shall ensure that sufficient supplies of roof support and ventilation materials, emergency plugs and suitable sealing materials are placed upwind and ready for use no further outby than one crosscut from the last open crosscut of the well intersection.
f. On the shift prior to intersecting the well, the operator shall service all equipment and check it for permissibility. On the shift that the well intersect is anticipated, water sprays, water pressures, and water flow rates used for dust and spark suppression shall be examined and any deficiencies corrected.
g. At the beginning of the shift when intersecting the well is anticipated, the operator shall calibrate the methane monitor(s) on the longwall, continuous mining machine, auger miner or cutting machine and loading machine.
h. 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 auger miner, continuous mining machine or longwall face is within 50 feet of the well (as determined from the well deviation survey) 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 will be conducted while the shearer is idle. 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.
i. 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.
J. 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.
k. 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. Adequate ventilation shall be maintained at all times.
1. 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 ofless than 1.0% are present in all areas that will be exposed to flames and sparks from the torch. Methane levels in all intake air courses, working places and the immediate section return shall be maintained less than 1.0% methane. 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, and at the location where torches are to be used.
m. Non-sparking (brass) tools will be located on the working section and will be used exclusively to expose and examine cased wells.
n. No person shall be permitted in the area while mining within 50 feet of the anticipated well intersect, except those actually engaged in the operation, including company personnel, representatives of the miners, personnel from MSHA, and personnel from the appropriate State agency.
o. 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.
p. 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. Additionally, the site specific well intersect plan and petition for modification shall be posted on the working section when mining within 50 feet of an anticipated well intersect. At the beginning of any shift when a well intersect is to occur all personnel underground shall be informed. All personnel underground shall also be familiar with the communication procedures to be used. Mine management shall ensure that all personnel can be immediately contacted to inform them of any problems that might develop during the well intersect. The communication system shall be tested prior to mining within 100 feet diameter of any well intersect and at the beginning of each shift thereafter until the well is intersected.
q. 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.
r. The provisions of this 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.
