SUPPLEMENTAL INFORMATION

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 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 modifications.
II. Petitions for Modification

Docket Number: M2007066C.

Petitioner: Knight Hawk Coal, LLC, 501 Barwick Road, Elkville, Illinois 62932.

Mine: Royal Falcon Mine, MSHA I.D. No. 1103162, located in Jackson County, Illinois

Regulation Affected: 30 CFR 75.503 (Permissible electric face equipment; maintenance) and 30 CFR 18.35 (Portable (trailing) cables and cords).

Modification Request: The petitioner requests a modification of the existing standard to increase the maximum length of cables supplying power to permissible equipment used in continuous mining sections. The petitioner states that: (1) This petition will only apply to trailing cables supplying threephase, 995volt power to continuous mining machines and trailing cables supplying threephase, 480volt power to roof bolters; (2) the maximum length of the 995volt continuous mining machine trailing cables will be 950 feet and the maximum length of the 480volt trailing cables for roof bolters will be 900 feet; (3) 995 volt continuous mining machine trailing cables will not be smaller than 2/0 and the 480volt trailing cables for roof bolters will not be smaller than 2 AWG; (4) all circuit breakers used to protect 2/0 trailing cables exceeding 850 feet in length will have instantaneous trip units calibrated to trip at 1,500 amperes and the trip setting will be sealed or locked and will have permanent legible permanent labels that will be maintained as legible to identify the circuit breaker as being suitable for protecting 2/0 cables; (5) replacement instantaneous trip units, used to protect 2/0 trailing cables, will be calibrated to trip at 1,500 amperes and the setting will be sealed or locked; (6) all circuit breakers used to protect 2 AWG trailing cables exceeding 700 feet in length will have instantaneous trip units calibrated to trip at 800 amperes, the trip setting will be sealed or locked, and the circuit breakers will have permanent legible labels that will be maintained as legible to identify the circuit breakers as being suitable for protecting 2 AWG cables; (7) replacement instantaneous trip units used to protect 2 AWG trailing cables will be calibrated to trip at 800 amperes and the setting will be sealed or locked; (8) the designated operator will visually examine the trailing cables during each production day to ensure that the cables are operating safely and the instantaneous settings of the calibrated breakers do not have seals or locks removed and do not exceed the stipulated settings; and (9) any trailing cable that is not in safe operating condition will be removed from service immediately and repaired or replaced. Persons may review a complete description of petitioner's alternative method and procedures at the MSHA address listed in the notice. The petitioner states that the alternative method will not be implemented until miners designated to examine the integrity of the seals or locks verify the shortcircuit settings, and proper procedures training has been provided for examining trailing cables for defects and damage. The petitioner further states that the miners will be trained in the terms and conditions of the Proposed Decision and Order, and within 60 days the petitioner will submit revisions of its Part 48 training plan to the District Manager that includes task training to comply with the final order. The petitioner asserts that the proposed alternative method will at all times guarantee no less than the same measure of protection to the miners.

Docket Number: M2007067C.

Petitioner: Mach Mining, LLC, P.O. Box 300, Johnson City, Illinois 62951.

Mine: Mach No. 1 Mine, MSHA I.D. No. 1103141 located in Williamson 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, through the use of alternative safety measures, the mining through or intersecting of certain oil and gas wells located within the projected workings of its No. 1 Mine to recover significant and valuable coal resources in an area of the mine penetrated by several abandoned oil and gas wells. The petitioner asserts that the proposed alternative method would provide the same measure of protection afforded the miners by application of the existing standard.

Docket Number: M2007068C.

Petitioner: KenAmerican Resources, Inc., 7590 State Route 181, Central City, Kentucky 42330.

Mine: Paradise Mine, MSHA I.D. No. 1517741 located in Muhlenberg County, Kentucky.

Regulation Affected: 30 CFR 75.364(b)(2) (Weekly examination).

Modification Request: The petitioner requests a modification of the existing standard to permit a measuring point location to be established in the Main East Parallel return at crosscut 13 (MPLME01) and in the Main North Parallel return at crosscut 169 (MPLMN02). The petitioner states that due to deteriorating roof conditions in these affected areas of the mine it is not desirable for normal travel for inspections and examinations. The petitioner asserts that the alternative method would at all times guarantee the same measure of protection as the existing standard.
