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 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) that the application of such standard to such mine will result in a diminution of safety to the miners in such mine. In addition, the regulations at 30 CFR 44.10 and 44.11 establish the requirements and procedures for filing petitions for modification.
II. Petitions for Modification
- Docket Number: M-2010-031-C.
Petitioner: D & C Mining Corporation, P.O. Box 148, Fries, Virginia 24330.
Mine: D & C Mining Corporation Mine, MSHA I.D. No. 15-18182, located in Harlan, County, Kentucky.
Regulation Affected: 30 CFR 75.507-1(a) (Electric equipment other than power-connection points; outby the last open crosscut; return air; permissibility requirements) and 30 CFR 18.35(a)(5)(i)(ii) (Portable (trailing) cables and cords).
Modification Request: The petitioner requests a modification of the existing standard to permit an increase in the maximum length of trailing cables supplying power to permissible pumps at the mine. The petitioner states that: (1) This petition will apply only to trailing cables supplying three-phase, 480-volt power for permissible pumps; (2) the maximum length of the 480-volt power for permissible pumps will be 2100 feet; (3) the 480-volt power for permissible pump trailing cables will not be smaller than
- Docket Number: M-2010-032-C.
Petitioner: M-Class Mining Company, P.O. Box 227, Johnston City, Illinois 62951.
Mine: MC No. 1 Mine, MSHA I.D. No. 11-03189, located in Franklin County, Illinois.
Regulation Affected: 30 CFR 75.1700 (Oil and gas wells).
Modification Request: The petitioner requests a modification of the existing standard to permit cleaning out, preparing, plugging and replugging of oil and gas wells utilizing the following terms and conditions: 1. District Manager Approval; (a) a safety barrier of 300 feet in diameter (150 feet between any mined area and a well) will be maintained around all oil and gas wells to include all active, inactive, abandoned, shut-in, previously plugged wells, and water injection wells, until approval to proceed with mining has been obtained from the District Manager. After District Manager approval, the mine operator will then mine within the safety barrier of the well, subject to the terms and conditions of this petition. 2. Plugging, and Replugging or Gas Wells; (1) the operator will 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 (the operator will provide the District Manager with all information it possesses concerning the geologic nature of the strata and the pressure of the well). The operator will remove all material from the entire diameter of the well, wall to wall; (2) the operator will prepare down-hole logs for each well. They will consist of a caliper survey and log(s) suitable for determining the top, bottom, and thickness of all coal seams and potential hydrocarbon producing strata and the location for a bridge plug. In addition, a journal will be maintained describing the depth and nature of each material encountered. The 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 will be maintained as part of this journal and provided to MSHA upon request; (3) When cleaning out the well, the operator will make a diligent effort to remove all of the casing in the well. If it is not possible to remove all of the casing, the operator will take appropriate steps to ensure that the annulus between the casing and between the casings and the well walls are filled with expanding (minimum 0.5% expansion upon setting) cement and contain no voids. The casing will be cut or milled at all mineable coal seam levels if it cannot be removed. Any casing that remains will be perforated or ripped. If the operator, using a casing bond log, can demonstrate to the satisfaction of the District Manager that all annuli in the well are already adequately sealed with cement, the operator will not be required to perforate or rip the casing for that particular well. When multiple casing and tubing strings are present in the coal horizon, any casing that remains will 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. The petitioner has listed a complete list of procedures that will be utilized when cleaning out, preparing, plugging, and replugging oil or gas wells. Persons may review these procedures at the MSHA address listed in this notice. The petitioner states that: (1) Within 30 days after this petition becomes final, revisions for the 30 CFR part 48 training plan will be submitted to the District Manager. The proposed revisions will include initial and refresher training regarding compliance with the terms and conditions stated in this petition. All miners in the mine-through of a well will be provided with training regarding the requirements of this petition prior to mining within 150 feet of the next well to be mined through; (2) the responsible person required by 30 CFR 75.1501 will be responsible for well intersection emergencies. The well intersection procedures will be reviewed by the responsible person prior to any planned intersection; and (3) within 30 days after this petition becomes final, the operator will submit proposed revisions for its approved mine emergency evacuation and firefighting plan required by 30 CFR 75.1501. The operator will revise the plans to include the hazards and evacuation procedures to be used for well intersections. All underground miners will be trained in the revised plans within 30 days of submittal of the revised evacuation plans. The petitioner asserts that the proposed alternative method will at all times guarantee no less than the same measure of protection afforded to the miners under 30 CFR 75.1700.
