Federal Register / Vol. 86, No. 156 / Tuesday, August 17, 2021 / Notices
Pittsburgh 8 coal seam, and the other applicable provisions in this petition still apply; or 4 If the casing cannot be removed, the casing shall be perforated from 400
feet below the Pittsburgh 8 coal seam, the annuli shall be cemented or otherwise filled, and the other applicable provisions in this petition still apply.
5 If the casing cannot be removed, the casing must be cut, milled, perforated, or ripped at sufficient intervals to facilitate the removal of any remaining casing in the coal seam by the mining equipment. Any casing which remains shall be cut, perforated, or ripped to permit the injection of cement into voids within and around the well.
All casing remaining at the Pittsburgh 8 coal seam shall be cut, perforated, or ripped at least every 5 feet from 10 feet below the coal seam to 10 feet above the coal seam.
6 If the mine operator, using a casing bond log, can demonstrate to the District Managers satisfaction that all annuli in the well are already adequately sealed with cement, the mine 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 horizons, 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.
e The petitioner proposed to use the following mandatory procedures when mining within a 100-foot diameter barrier around the Esther Clark 1H and 3H Gas Wells.
1 A representative of the mine 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 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 mine operator shall intersect a well on a shift approved by the District Manager. The mine operator shall notify the District Manager and the miners representative in sufficient time prior to intersecting a well to provide an

opportunity to have representatives present.
3 When using continuous mining methods, the mine operator shall install drivage sites at the last open crosscut near the place to be mined to ensure intersection of the well. The drivage sites shall not be more than 50 feet from the well. When using longwall-mining methods, distance markers shall be installed on 5-foot centers for a distance of 50 feet in advance of the well in the headgate entry and in the tailgate entry.
4 When either the conventional or continuous mining method is used, the mine operator shall ensure that firefighting equipment including fire extinguishers, rock dust, and sufficient fire hose to reach the workingface area of the well intersection 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 mine operator shall maintain the water line to the belt conveyor tailpiece along with a sufficient amount of fire hose to reach the farthest point of penetration on the section. When the longwall mining method is used, a hose to the longwall water supply is sufficient.
5 The mine operator shall ensure that sufficient supplies of roof support and ventilation materials shall be available and located at the last open crosscut. In addition, emergency plugs and suitable sealing materials shall be available in the immediate area of the well intersection.
6 On the shift prior to intersecting the well, the mine 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 he examined and any deficiencies corrected.
7 The mine operator shall calibrate the methane monitors on the longwall, continuous mining machine, or cutting machine and loading machine on the shift prior to intersecting the well.
8 When mining is in progress, the mine operator shall test for methane with a handheld methane detector at least every 10 minutes from when mining with the continuous mining machine or longwall face is within 30
feet of the well until the well is intersected. During the actual cutting process, no individual shall be allowed on the return side until the well intersection has been completed and the area has been examined and declared safe. All workplace examinations on the return side of the shearer will be conducted while the shearer is idle. The mine operators 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. On longwall sections, rockdusting shall be conducted and placed on the roof, rib, and floor up to both the headgate and tailgate gob.
10 When the well is intersected, the mine operator shall de-energize all equipment and thoroughly examine and determine the area to be safe before permitting mining to resume.
11 After a well has been intersected and the working place determined to be safe, mining shall continue inby the well a sufficient distance to permit adequate ventilation around the area of the well.
12 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 mine operator shall apply a thick layer of rock dust to the roof, face, floor, ribs, and any exposed coal within 20 feet of the casing prior to the use of torches.
13 Non-sparking brass tools will be available and will be used exclusively to expose and examine cased wells.
14 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.
15 The mine operator shall alert all personnel in the mine to the planned intersection of the well prior to their going underground if the planned intersection is to occur during their shift. This warning shall be repeated for all shifts until the well has been mined through.
16 The well intersection shall be under the direct supervision of a certified individual. Instructions concerning the well intersection shall be issued only by the certified individual in charge.
17 If the mine operator cannot find the well in the longwall panel or if a development section misses the anticipated intersection, the mine operator shall cease mining to examine
