| In the matter of Twentymile Coal Company Foidel Creek Mine I.D. No. 05-03836 | Petition for Modification Docket No. M-98-055-C |
On May 18, 1998, a petition was filed seeking a modification of the application of 30 CFR 75.500(b) to Petitioner's Foidel Creek Mine, located in Oak Creek, Colorado. The Petitioner on December 2, 1998, requested that the petition be modified to seek a modification of the application of 30 CFR 75.1002-1(a) instead of 75.500(b). The Petitioner alleges that application of this standard will result in a diminution of safety to the miners and that the alternative method proposed in the petition will at all times guarantee no less than the same measure of protection afforded by the standard.
MSHA personnel conducted an investigation of the petition and filed a report of their findings and recommendations with the Administrator for Coal Mine Safety and Health. After a careful review of the entire record, including the petition, and MSHA's investigative report and recommendation, a Proposed Decision and Order was issued on March 4, 1999. Subsequently, District 9 personnel commented that the recording requirement in stipulation No. 5 was unnecessary and that the language in stipulation No. 12 needed to be clarified. Therefore, this new PDO is issued which deletes the recording requirement in stipulation No. 5, and also clarifies language in stipulation No. 12. This PDO supersedes the PDO issued on March 4, 1999.
The alternative method proposed by the Petitioner (as amended by the recommendations of MSHA) will at all times guarantee no less than the same measure of protection afforded the miners under 30 CFR 75.1002-1(a).
On the basis of the petition and the findings of MSHA's investigation, Twentymile Coal Company is granted a modification of the application of 30 CFR 75.1002-1(a) to its Foidel Creek Mine.
Wherefore, pursuant to the authority delegated by the Secretary of Labor to the Administrator for Coal Mine Safety and Health, and pursuant to Section 101(c) of the Federal Mine Safety and Health Act of 1977, 30 U.S.C., sec. 811(c), it is ordered that.Twentymile Coal Company's Petition for Modification of the application of 30 CFR 75.1002-1(a) in the Foidel Creek Mine is hereby:
- GRANTED, for the use of low voltage or battery powered non-permissible electronic testing and diagnostic equipment within 150 feet of pillar workings, under controlled conditions, conditioned upon compliance with the following terms and conditions:
- 1. The use of non-permissible low voltage or battery powered electronic testing and diagnostic equipment shall be limited to laptop computers, oscilloscopes, vibration analysis machines, cable fault detectors, point temperature probes, infrared temperature devices, voltage, current and power measurement recorders, pressure and flow measurement devices, signal analyzer devices, ultrasonic thickness gauges, and electronic tachometers. Other testing and diagnostic equipment may be used if approved in advance by MSHA's District Office.
- 2. Non-permissible electronic testing and diagnostic equipment shall be used only when equivalent permissible equipment does not exist.
- 3. All other test and diagnostic equipment used within 150 feet of pillar workings shall be permissible.
- 4. All non-permissible electronic testing and diagnostic equipment used within 150 feet of pillar workings shall be examined, by a qualified person as defined in existing 30 CFR 75.153, prior to being used to ensure the equipment is being maintained in a safe operating condition. The examination results shall be recorded in the weekly examination of electrical equipment book and shall be made available to an authorized representative of the Secretary and the miners at the mine.
- 5. A qualified person as defined in existing 30 CFR 75.151 shall continuously monitor for methane immediately before and during the use of non-permissible electronic test and diagnostic equipment within 150 feet of pillar workings.
- 6. Non-permissible electronic testing and diagnostic equipment shall not be used if methane is detected in concentrations at or above 1.0 percent methane. When 1.0 percent or more of methane is detected while the non-permissible electronic equipment is being used, the equipment shall be de-energized immediately and the non-permissible electronic equipment withdrawn to more than 150 feet outby pillar working.
- 7. All hand-held methane detectors shall be MSHA approved and maintained in permissible and proper operating condition as defined in existing 30 CFR 75.320.
- 8. Except for the time necessary to trouble shoot under actual mining conditions, coal production in the longwall section shall cease. However, coal may remain in or on the equipment such as the panline in order to test and diagnose the equipment under "load."
- 9. Non-permissible electronic test and diagnostic equipment shall not be used to test equipment when float coal dust is in suspension.
- 10. All electronic test and diagnostic equipment shall be used in accordance with the manufacturer's recommended safe use practices.
- 11. Qualified personnel engaged in the use of electronic test and diagnostic equipment shall be properly trained to recognize the hazards and limitations associated with the use of electronic test and diagnostic equipment.
- 12. The non-permissible low voltage or battery powered electronic testing and diagnostic equipment shall not be put into service until MSHA has inspected the equipment and determined that it is in compliance with all the above terms and conditions. The Petitioner shall notify MSHA before additional non-permissible electronic testing and diagnostic equipment is put into service within 150 feet of pillar workings. The notice shall provide a reasonable time for MSHA to inspect such equipment before being used.
- 13. Within 60 days after this Proposed Decision and Order becomes final, the Petitioner shall submit proposed revisions for its approved 30 CFR Part 48 training plan to the Coal Mine Safety and Health District Manager. In addition to the requirements specified in items Nos. 10 and 11, these proposed revisions shall specify initial and refresher training regarding the terms and conditions stated in the Proposed Decision and Order.
If a hearing is requested, the request shall contain a concise summary of position on the issues of fact or law desired to be raised by the party requesting the hearing, including specific objections to the proposed decision.

If no request for a hearing is filed within 30 days after service thereof, the Decision and Order will become final and must be posted by the operator on the mine bulletin board at the mine.
