SUPPLEMENTARY 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 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-2013-035-C.

Petitioner: Five Star Mining, Inc., 6594 West State Road 56, Petersburg, Indiana 47567.

Mine: Prosperity Mine, MSHA I.D. No. 12-02249, located in Pike County, Indiana.

Regulation Affected: 30 CFR 75.503 (Permissible electric face equipment; maintenance), 30 CFR 18.35(a)(5)(i)(ii) (Portable (trailing) cables and cords).

Modification Request: The petitioner requests a modification of the existing standard to permit the maximum length of trailing cables to be increased for supplying power to permissible pumps in the Prosperity Mine. The petitioner states that:

(1) This petition will apply only to trailing cables supplying three-phase, 480-volt, 3-phase power for permissible pumps.

(2) The maximum length of the trailing cables supplying 480-volts to permissible pumps will be 4,000 feet.

(3) Trailing cables or cords over 500 feet supplying power to 480-volt permissible pumps will not be smaller than No. 6 American Wire Gauge (AWG).

(4) All circuit breakers used to protect the No. 6 AWG trailing cables exceeding 550 feet in length will have an instantaneous trip unit calibrated to trip at 60 amperes. The trip setting of these circuit breakers will be sealed or locked so that the setting cannot be changed, and will have permanent, legible labels. Each label will identify the circuit breaker as being suitable for protecting No. 6 AWG cables. This label will be maintained legible.

(5) Replacement instantaneous trip units used to protect No. 6 AWG trailing cables will be calibrated to trip at 60 amperes and this setting will be sealed or locked.

(6) All circuit breakers used to protect the No. 2 AWG trailing cables exceeding 700 feet in length will have an instantaneous trip unit calibrated to trip at 150 amperes. The trip setting of these circuit breakers will be sealed or locked so that the setting cannot be changed, and these circuit breakers will have permanent, legible labels. Each label will identify the circuit breaker as being suitable for protecting No. 2 AWG trailing cables. This label will be maintained legible.

(7) Replacement instantaneous trip units used to protect No. 2 AWG trailing cables will be calibrated to trip at 150 amperes and this setting will be sealed or locked.

(8) All components that provide short-circuit protection will have a sufficient interruption rating in accordance with the maximum calculated fault currents available.

(9) The short-circuit setting will not exceed the setting specified in the approval documentation or 70 percent of the minimum available current, whichever is less.

(10) Permanent warning labels will be installed and maintained on the cover(s) of the power center or distribution box to identify the location of each sealed short-circuit protection device. These labels will warn miners not to change or alter the sealed short-circuit settings.

(11) Within 60 days after this proposed decision and order becomes final, the proposed revisions for the petitioner's approved 30 CFR part 48 training plan will be submitted to the District Manager. The training plan will include the following:

(a) Mining methods and operating procedures for protecting the trailing cables against damage.

(b) Proper procedures for examining the trailing cables to ensure safe operating condition.

(c) The hazards of setting the short-circuit interrupting device(s) too high to adequately protect the trailing cables.

(d) How to verify that the circuit interrupting device(s) protecting the trailing cable(s) are properly set and maintained.

The petitioner further states that procedures specified in 30 CFR 48.3 for proposed revisions to approved training plans will apply.

The petitioner asserts that the alternative method will guarantee no less than the same measure of protection for all miners than that of the existing standard.

Docket Number: M-2013-036-C.

Petitioner: Pinnacle Mining Company, LLC, P.O. Box 338, Pineville, West Virginia 24874,

Mine: Pinnacle Mine, MSHA I.D. No. 46-01816, located in Wyoming County, West Virginia.

Regulation Affected: 30 CFR 75.500(d) (Permissible electric equipment).

Modification Request: The petitioner requests a modification of the existing standard to permit an alternative method of compliance to allow the use of battery-powered nonpermissible surveying equipment in or inby the last open crosscut, including, but not limited to, portable battery-operated mine transits, total station surveying equipment, distance meters, and data loggers. The petitioner states that:

(1) To comply with requirements for mine ventilation maps and mine maps in 30 CFR 75.372 and 75.1200, use of the most practical and accurate surveying equipment is necessary.

(2) Application of the existing standard would result in a diminution of safety to the miners. Underground mining by its nature and size, and the complexity of mine plans, requires that accurate and precise measurements be completed in a prompt and efficient manner. The petitioner proposes the following as an alternative to the existing standard:

(a) Nonpermissible electronic surveying equipment may be used. Such nonpermissible surveying equipment includes portable battery-operated total station surveying equipment, mine transits, distance meters, and data loggers.

(b) All nonpermissible electronic surveying equipment to be used in or inby the last open crosscut will be examined prior to use to ensure the equipment is being maintained in a safe operating condition. These examinations will include the following steps:

(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 to ensure that it is securely fastened.

(c) The results of such examinations will be recorded and retained for one year and made available to MSHA on request.

(d) A qualified person as defined in 30 CFR 75.151 will continuously monitor for methane immediately before and during the use of nonpermissible surveying equipment in or inby the last open crosscut.

(e) Nonpermissible surveying equipment will not be used if methane is detected in concentrations at or above one percent for the area being surveyed. When methane is detected at such levels while the nonpermissible surveying equipment is being used, the equipment will be deenergized immediately and the nonpermissible electronic equipment withdrawn outby the last open crosscut.

(f) All hand-held methane detectors will be MSHA-approved and maintained in permissible and proper operating condition as defined in 30 CFR 75.320.

(g) Batteries in the surveying equipment will be changed out or charged in fresh air outby the last open crosscut.

(h) Qualified personnel who use surveying equipment will be properly trained to recognize the hazards and limitations associated with the use of nonpermissible surveying equipment in areas where methane could be present.

(i) The nonpermissible surveying equipment will not be put into service until MSHA has initially inspected the equipment and determined that it is in compliance with all the terms and conditions in this petition.

The petitioner asserts that the proposed alternative method will at all times guarantee no less than the same measure of protection as that afforded by the existing standard.
