AGENCY:
Mine Safety and Health Administration (MSHA), Labor.
ACTION:
Notice of affirmative decisions issued by the Administrators for Coal Mine Safety and Health and Metal and Nonmetal Mine Safety and Health on petitions for modification of the application of mandatory safety standards.
SUMMARY:
Under section 101 of the Federal Mine Safety and Health Act of 1977, the Secretary of Labor (Secretary) may allow the modification of the application of a mandatory safety standard to a mine if the Secretary determines either that an alternate method exists at a specific mine that will guarantee no less protection for the miners affected than that provided by the standard, or that the application of the standard at a specific mine will result in a diminution of safety to the affected miners.
Final decisions on these petitions are based on the petitioner's statements, comments and information submitted by interested persons, and a field investigation of the conditions at the mine. MSHA, as designee of the Secretary, has granted or partially granted the requests for modification listed below. In some instances, the decisions are conditioned upon compliance with stipulations stated in the decision. The term FR Notice appears in the list of affirmative decisions below. The term refers to the Federal Register volume and page where MSHA published a notice of the filing of the petition for modification.
FOR FURTHER INFORMATION CONTACT:
Petitions and copies of the final decisions are available for examination by the public in the Office of Standards, Regulations, and Variances, MSHA, 1100 Wilson Boulevard, Room 2350, Arlington, Virginia 22209. For further information contact Barbara Barron at 202-693-9447.

Affirmative Decisions on Petitions for Modification
Docket No.: M-2002-028-C.
FR Notice: 67 FR 19284.
Petitioner: Consolidation Coal Company.
Regulation Affected: 30 CFR 75.364(b)(2).
Summary of Findings: Petitioner's proposal is to amend the Proposed Decision and Order (PDO) for its previously granted petition for modification, docket number M-1993-275-C, as it relates to air courses ventilating the No. 3 North seals and the No. 21/2 North seals at the Loveridge No. 22 Mine. The petitioner's request is to amend paragraph 4 of the previous PDO to permit a certified person to conduct weekly examinations of each of the eight (8) monitoring stations to evaluate the quality of methane and oxygen content (measured by a hand-held instrument) and quantity of air entering and exiting the monitoring station, and to determine air course leakage. This is considered an acceptable alternative method for the Loveridge No. 22 Mine. MSHA grants the petition for modification for continuous monitoring using intrinsically safe sensors installed as part of the mine's Atmospheric Monitoring System (AMS) and weekly evaluation of air entering and leaving the intake air courses ventilating No. 3 North seals and No. 21/2 North seals for the Loveridge No. 22 Mine with conditions.
Docket No.: M-2002-043-C.

Petitioner: Lone Mountain Processing, Incorporated.
Regulation Affected: 30 CFR 75.901(a).
Summary of Findings: Petitioner's proposal is to use a 480-volt, three-phase, 300KW/375VA diesel powered generator (DPG) set to supply power to a three-phase wye connected 300 KVA auto transformer and three-phase 480-volt and 995-volt power circuits. This is considered an acceptable alternative method for the Huff Creek Mine No. 1. MSHA grants the petition for modification for the LIMA MAC, 480-volt, Model No. 68MDL10094, 300KW diesel powered generator (DPG) set, supplying power to a 300 KVA autotransformer to develop 995-volt power circuits for the Huff Creek Mine No. 1 with conditions.
Docket No.: M-2002-073-C.
FR Notice: 67 FR 59318.
Petitioner: Mountain Coal Company, L.L.C.
Regulation Affected: 30 CFR 75.352.
Summary of Findings: Petitioner's proposal is to temporarily use a portion of the #4 Belt Entry as a return air course and use specific stipulations listed in the petition for modification to achieve an equivalent level of safety when implementing its proposed alternative method. These stipulations will remain in effect only until a return air course can be established between the E-seam and the shaft that connects the B-seam to the F-seam. This is considered an acceptable alternative method for the West Elk Mine. MSHA grants the petition for modification for use of belt haulage in a return air course, only between the F and B coal seams along the No. 4 belt in the No. 1 Rock Slope entry, during initial development of the E-seam, between the rock slopes and the inner-seam return air shaft, conditioned upon compliance with the terms and conditions listed in the Proposed Decision and Order for the West Elk Mine.

FR Notice: 68 FR 23501.
Petitioner: Baylor Mining, Inc.
Regulation Affected: 30 CFR 75.364(b)(2).
Summary of Findings: Petitioner's proposal is to have a certified person check the quantity and quality of air at four monitoring stations (identified as EP No. 3, EP No. 4, EP No. 5, and EP No. 6) intake and return air courses on a weekly basis in the area approximately 700 feet of the return air course in the 1st Left section of the Beckley Crystal Mine due to extremely hazardous roof conditions and several roof falls. The petitioner asserts that traveling the affected areas would be unsafe. The petitioner filed this petition for modification seeking to modify the application of 30 CFR 75.364(a)(1). MSHA determined that the petitioned area is not a worked out area and is best classified as a designated return air course. Therefore, the petition is being treated as a request to modify the application of 30 CFR 75.364(b)(2). This is considered an acceptable alternative method for the Beckley Crystal Mine. MSHA grants the petition for modification for the examination of approximately 700 feet of unsafe-to-travel return air course in the 1st Left Section from Spad No. 1839 to one block inby Spad No. 1792 for the Beckley Crystal Mine with conditions.
Docket No.: M-2003-038-C.

Summary of Findings: Petitioner's proposal is to establish evaluation points to monitor the quality, quantity, and direction of air flow through the A Mains intake air course starting at Spad 428 and ending at Spad 388, a distance of 3,100 feet. The evaluation points will be established at the inby end of the intake air course near Spad 388 to test for methane accumulation oxygen deficiency, quantity of air and for the proper direction of air flow; the evaluation points will be examined on a weekly basis; test results will be recorded in a book provided on the surface; and preshift examination of the belt side of the intake stopping line separating the belt from the intake air course will be made every 8 hours and any hazardous conditions found will be recorded in a book provided on the surface. This is considered an acceptable alternative method for the Spruce Fork Mine No. 1. MSHA grants the petition for modification for evaluation of the unsafe-for-examination intake air course segment (approximately 3,100 feet) known as the A Mains Air Course Area for the Spruce Fork Mine No. 1 with conditions.
