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 of Labor 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-2015-019-C.
Petitioner: UtahAmerican Energy, Inc., 794 North “C” Canyon Road, P.O. Box 910, East Carbon, Utah 84520.
Mine: Lila Canyon Mine, MSHA I.D. No. 42-02241, located in Carbon County, Utah.
Regulation Affected: 30 CFR 75.500(d) (Permissible electric equipment).
Modification Request: The petitioner requests a modification of the existing standard to permit the use of battery-powered nonpermissible surveying equipment in or inby the last open crosscut, as it pertains to the use of non-permissible surveying equipment, including total stations and theodolites with low-voltage batteries if they have an IP rating of 66 or higher subject to the conditions of the petition. The petitioner states that:
(1) Nonpermissible electronic surveying equipment will only be used until equivalent permissible electronic surveying equipment is available or if viable new mechanical surveying equipment is not commercially available.
(2) Lila Canyon will maintain a logbook for electronic surveying equipment. The logbook will be kept with each corresponding instrument. The logbook will contain the date of manufacture and/or purchase of each particular piece of electronic surveying equipment. The logbook will be made available to MSHA on request.
(3) All nonpermissible electronic surveying equipment to be used in or inby the last open crosscut will be examined by the person that will operate the equipment prior to taking Start Printed Page 67429the equipment underground to ensure the equipment is being maintained in a safe operating condition. These checks will include:
(i) Checking the instrument for any physical damage and the integrity of the case.
(ii) Removing the battery and inspecting for corrosion.
(iii) Inspecting the contact points to ensure a secure connection to the battery.
(iv) Reinserting the battery and powering up and shutting down to ensure proper connections.
(v) Checking the battery compartment cover or battery attachment to ensure that it is securely fastened.
(4) Recording the results of the inspection in the equipment logbook.
(5) The equipment will be examined at least weekly by a qualified person as defined in 30 CFR 75.153. The examination results will be recorded weekly in the equipment logbook. Inspection entries in the logbook may be expunged after one year.
(6) All nonpermissible electronic surveying equipment will be serviced according to the manufacturer's recommendations. Dates of service will be recorded in the equipment logbook and will include a description of the work performed.
(7) The nonpermissible surveying equipment that will be used in or inby the last open crosscut will not be put into service until MSHA has initially inspected the equipment and determined that it is in compliance.
(8) Nonpermissible surveying equipment will not be used if methane is detected in concentrations at or above 1.0 percent methane. When 1.0 percent or more methane is detected while the nonpermissible surveying equipment is being used, the equipment will be deenergized immediately and withdrawn outby the last open crosscut. Prior to returning inby the last open crosscut, all requirements of 30 CFR 75.323 will be complied with.
(9) As an additional safety check, prior to setting up and energizing nonpermissible electronic surveying equipment in or inby the last open crosscut, the surveyor(s) will conduct a visual examination of the immediate area for evidence that the areas appear to be sufficiently rock dusted and for the presence of accumulated float coal dust. If the rock dusting appears insufficient or the presence of accumulated coal dust is observed, the equipment may not be energized until sufficient rock dust has been applied and/or the accumulations of coal dust have been cleaned up. If nonpermissible electronic surveying equipment is to be used in an area that is not rocked dusted within 40 feet of a working face where a continuous miner is used to extract coal, the area will be rock dusted prior to energizing the electronic surveying equipment.
(10) All hand-held methane detectors will be MSHA approved and maintained in permissible and proper operating condition as defined by 30 CFR 75.320. All methane detectors must provide visual and audible warnings when methane is detected at or above 1.0 percent.
(11) Prior to energizing any of the nonpermissible surveying equipment in or inby the last open crosscut, methane tests must be made no more than eight inches from the roof or floor at the location of the equipment.
(12) All areas to be surveyed will be pre-shifted according to 30 CFR 75.360 prior to surveying. If the area was not pre-shifted, a supplemental examination according to 30 CFR 75.361 will be performed before any non-certified person enters the area. If the area has been examined according to 30 CFR 75.360 or 30 CFR 75.361, an additional examination is not required.
(13) A qualified person as defined in existing 30 CFR 75.151 will continuously monitor for methane immediately before and during the use of nonpermissible surveying equipment inby the last open crosscut. A second person in the surveying crew, if there are two people in the crew, will also continuously monitor for methane. That person will either be a qualified person as defined in 30 CFR 75.151 or will be in the process of being trained to be a qualified person but will not make such tests for a period of 6 months, as required by 30 CFR 75.151. On completion of the 6-month training period, the second person on the survey crew must become qualified in order to continue on the survey crew. If the surveying crew consists of one person, such person will monitor for methane with two separate devices. While the equipment is used in or inby the last open crosscut, one qualified person who is continuously monitoring for methane will remain with the electronic surveying equipment.
(14) Batteries contained in the surveying equipment must be “changed out” or “charged” in intake air outby the last open crosscut. Replacement batteries for the electronic surveying equipment will not be brought in or inby the last open crosscut. On each entry into the mine, all batteries for the electronic surveying equipment must be fully charged.
(15) When using nonpermissible electronic surveying equipment inby the last open crosscut the surveyor must confirm by measurement or by inquiry of the person in charge of the section that the air quantity on the section, on that shift, in the last open crosscut or coming to the longwall face is the quantity that is required by the mine's ventilation plan.
(16) Nonpermissible electronic surveying equipment will not be used when coal production is occurring in the section. All mining in the section will cease prior to use of the equipment in or inby the last open crosscut.
(17) Personnel engaged in the use of surveying equipment will be properly trained to recognize the hazards and limitations associated with the use of surveying equipment in areas where methane could be present.
(18) All persons who operate nonpermissible electronic surveying equipment will receive specific training on the terms and conditions of the proposed decision and order before using nonpermissible electronic surveying equipment in or inby the last open crosscut. A record of the training will be kept with the other training records.
(19) Within 60 days after the Proposed Decision and Order (PDO) becomes final, the petitioner will submit proposed revisions for their approved part 48 training plan to the District Manager. The revisions will specify initial and refresher training regarding the terms and conditions in the PDO. When training is conducted on the terms and conditions stated in the PDO, an MSHA Certificate of Training (Form 5000-23) will be completed. Comments on the certificate of training will indicate surveyor training.
(20) Lila Canyon will replace or retire from service any electronic surveying instrument that was acquired prior to December 31, 2001, within one year of the PDO becoming final. Lila Canyon will replace or retire from service any electronic surveying instrument that was acquired between January 1, 2002 and December 31, 2007; and within two years of the PDO becoming final. Within three years of the date that the PDO becomes final, Lila Canyon will replace or retire from service any electric theodolite that was acquired more than five years prior to the date that the PDO becomes final, or any total station acquired more than ten years prior to the day that the PDO becomes final. After five years, Lila Canyon will maintain a cycle of purchasing new electronic surveying equipment whereby theodolites will be no older than five years from date of manufacture and total stations will be no older than 10 years from date of manufacture.Start Printed Page 67430
(21) Lila Canyon is responsible for seeing that all surveying contractors hired by Lila Canyon are using relatively new electronic equipment, i.e., theodolites no older than five years from date of manufacture and total stations no older than 10 years from date of manufacture. The conditions of use in the PDO will apply to all nonpermissible electronic surveying equipment used in or inby the last open crosscut regardless of whether the equipment is used by Lila Canyon or by an independent contractor. Nonpermissible equipment will not be used where float coal dust is in suspension.
The petitioner asserts that application of the existing standard will result in a diminution of safety to the miners and that the proposed alternative method will at all times guarantee no less than the same measure of protection afforded by the existing standard.
