This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status. For complete information about, and access to, our official publications and services, go to About the Federal Register on NARA's archives.gov.
The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.

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 Numbers: M-2010-020-C.
Petitioner: The Wolf Run Mining Company, Route 3, Box 146, Philippi, West Virginia 26416.
Mine: Sentinel Mine, MSHA I.D. No. 46-04168, located in Barbour County, West Virginia.
Regulation Affected: 30 CFR 75.1909(b)(6) (Non-permissible diesel-powered equipment; design and performance requirements).
Modification Request: The petitioner requests a modification of the existing standard to permit the Getman Roadbuilder, Serial Number 379514 to be operated as it was originally designed, without front brakes. The petitioner states that: (1) The rule does not address equipment with more than four wheels, specifically the Getman Roadbuilder, Model RDG-1504S, with six wheels; (2) the machine has dual brake systems on the four rear wheels, and is designed to prevent loss of braking due to a single component failure; (3) seventy-four percent (74%) of the machines total weight is over the four (4) rear wheels; and (4) with the weight distribution, brakes on the rear of the machine are sufficient to safely stop the machine. The petitioner further states that: (1) Training will be provided to the grader operators to lower the moldboard to provide additional stopping capability in emergency situations and recognize the appropriate speeds to use on different roadway conditions; and (2) limit the maximum speed to 10 miles per hour. The petitioner asserts that the proposed alternative method will provide no less than the same measure of protection at the Sentinel Mine than would be provided with compliance with the existing standard.
Docket Numbers: M-2010-023-C.
Petitioner: Rosebud Mining Company, 301 Market Street, Kittanning, Pennsylvania 16201.
Mines: Tracy Lynne Mine, MSHA I.D. No. 36-08603, Clementine Mine, MSHA I.D. No. 36-08862, both located in Armstrong County, Pennsylvania; Penfield Mine, MSHA I.D. No. 36-09355, located in Clearfield County, Pennsylvania; Mine 78, MSHA I.D. No. 36-09371, located in Somerset County, Pennsylvania; and Heilwood Mine, MSHA I.D. No. 36-09407, Lowry Mine, MSHA I.D. No. 36-09287, Toms Run Mine, MSHA I.D. No. 36-08525, and Cherry Tree Mine, MSHA I.D. No. 36-09224, all located in Indiana County, Pennsylvania.
Modification Request: The petitioner requests a modification of the existing standard to permit the maximum length of the 480-volt trailing cables for supplying power to the Fletcher Roof Ranger II Twin Boom Roof Bolters to be 950 feet. The petitioner states that: (1) The trailing cables for the 480-volt Fletcher Roof Ranger II Roof Bolter will Start Printed Page 29785not be smaller than No. 2 American Wire Gauge (AWG) cable; (2) all circuit breakers used to protect the No. 2 AWG trailing cables exceeding 700 feet in length will have instantaneous trip units calibrated to trip at 500 amperes. The trip setting of these circuit breakers will be sealed to insure that the settings on the breakers cannot be changed, and will have permanent, legible labels. Each label will identify the circuit breaker as being suitable for protecting the No. 2 AWG cables; (3) replacement circuit breakers and/or instantaneous trip units, used to protect the No. 2 AWG trailing cables will be calibrated to trip at 500 amperes, and the setting to be sealed; (4) all components that provide short-circuit protection will have a sufficient interruption rating in accordance with the maximum calculated fault current available; (5) the No. 2 AWG cables and the circuit breakers will be examined in accordance with all 30 CFR provisions during each production day; (6) permanent warning labels will be installed and maintained on the load center identifying the location of each short-circuit protective device. These labels will warn miners not to change or alter the settings of these devices; (7) the affected trailing cables will be de-energized and repaired if the cables are damaged in any way during the shift; (8) the alternative method will not be implemented until after all miners who have been designated to operate the Roof Ranger II, or any other person designated to examine the trailing cables or trip settings on the circuit breakers have received proper training as to the performance of their duties; and (9) within sixty (60) days after the Proposed Decision and Order becomes final, proposed revisions for its approved 30 CFR part 48 training plan will be submitted to the District Manager. The proposed revisions will specify task training for miners designated to examine the trailing cables for safe operating conditions and verify that the short-circuit settings of the circuit interrupting device(s) that protect the affecting trailing cables do not exceed the specified setting(s) in Item No. 3. Training will include the following elements: (a) The hazards of setting the short-circuit interrupting device(s) too high to adequately protect the trailing cables; (b) how to verify that the interrupting device(s) protecting the trailing cable(s) are properly set and maintained; (c) mining methods and operating procedures that will protect the trailing cables against damage; and (d) the proper procedure for examining the trailing cable to insure that the cable(s) are in safe operating condition by a visual inspection of the entire cable, observing the insulation, the integrity of the splices, nicks and abrasions. The petitioner states that the procedures as specified in 30 CFR 48.3 for approval of proposed revisions to approved training plans will apply. The petitioner asserts that the proposed alternative method will at all times guarantee no less than the same measure of protection afforded the miners by such standard with no diminution of safety to miners.Start Signature
