# SUPPLEMENTARY INFORMATION:

Section 101(c) of the Federal Mine Safety and Health Act of 1977 and title 30 of the Code of Federal Regulations (CFR) part 44 govern the application, processing, and disposition of petitions for modification.

## 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. The application of such standard to such mine will result in a diminution of safety to the miners in such mine.

In addition, sections 44.10 and 44.11 of 30 CFR establish the requirements for filing petitions for modification.

## II. Petition for Modification

*Docket Number:*                     M-2024-053-C.                

*Petitioner:*                     Marfork Coal Company, LLC, P.O. Box 457, Whitesville, West Virginia 25209.                

*Mine:*                     Black Eagle Mine, MSHA ID No. 46-09550, located in Raleigh County, West Virginia.                

*Regulation Affected:*30 CFR 75.312(c) (Main mine fan examinations and records).                

*Modification Request:*                     The petitioner requests a modification of 30 CFR 75.312(c) to permit testing the automatic fan stopping signal device without shutting down the mine fan and removing the miners.                

The petitioner states that:

(a) The mine extracts coal by the room and pillar method of mining and operates three continuous miner sections producing coal five to six days per week.

(b) The mine has personnel underground 24 hours per day, 7 days per week.

(c) The mine is ventilated by one, Jeffrey model 8HUA117, 1,500 horsepower (hp) and 895 revolutions per minute (rpm), mine fan.

(d) The fan operates at approximately 10 inches of water gauge and moves approximately 635,000 cubic feet per minute.

(e) The mine liberates 777,272 cubic feet of methane every 24 hours as of April 16, 2024.

(f) Currently, the mine fan stops every 31 days to check the fan signal device.

(g) If fan outage lasts longer than 1, 3, or 48 hours, then the fan is required to run for 1, 2, or 3 hours, respectively, before a certified examiner can re-enter the mine to conduct the required examinations.

(h) It is unfavorable to stop the fan and disrupt the ventilation due to the mine liberating methane and personnel being underground 24 hours per day, 7 days per week, making it impossible to schedule a time when the fan stoppage signal can be checked without miners being underground.

The petitioner proposes the following alternative method:

(a) The main fine fan shall be provided with a fan alarm signal system consisting of the following:

(1) A ridged plastic tubing protected by steel conduit extending from the fan ductwork to a Photohelic gauge and chart recorder to continuously monitor the fan operating pressure. An automatic fan signal is activated when the fan pressure falls below 50 percent of the normal operating pressure (which currently equals 5 inches of water gauge) as measured by the Photohelic gauge. This alarm shall be visible and audible in the dispatcher's office.

(2) A Pyott Boone Belt (PBE) model #1610 TA analog scanner monitors the fan. When the fan loses electrical power, the PBE scanner sends a signal to the dispatch office which sounds an alarm. This additional alarm provides a backup in the event the Photohelic gauge or its contacts fail to automatically signal.

(b) The automatic fan signal device shall be tested every seven days by manually operating a valve (Ham-Let valve) near the Photohelic gauge and fan pressure recording chart reducing the pressure on the water gauge to simulate a fan stoppage, causing the activation of the fan signal. The actuation of the fan alarm shall be verified by a responsible person at the location where the responsible person is always on duty when anyone is underground. Once this seven-day test of the alternative method has been successfully repeated for four consecutive weeks, the test frequency shall change to at least every 31 days.

(c) The automatic fan signal device and signal alarm shall be tested every six months by stopping the fan to ensure that the automatic signal device causes the alarm to activate when the fan shuts down.

(d) By the end of the shift on which the test of the automatic fan signal device is completed, person(s) performing the test shall record the result of the test in a secure book. The record book shall be retained at a surface location at the mine for at least one year and shall be made available for inspection by an Authorized Representative of the Secretary.

(e) Within 60 days of the Proposed Decision and Order (PDO) granted by MSHA, Marfork shall submit proposed revisions for its approved 30 CFR 48 training plan to the MSHA District Manager. These proposed revisions shall include initial and refresher training regarding compliance with the PDO granted by MSHA. Miners who are to perform the test under the PDO granted by MSHA shall be trained at least annually on the proper method of testing upon his or her initial assignment to these responsibilities.

(f) The petitioner asserts that this Petition for Modification of Application of Mandatory Standard has been posted on the employee bulletin board at the Black Eagle Mine as of August 30, 2024, and there are no representatives of miners at this operation.

                    The petitioner asserts that the alternate method proposed will at all times guarantee no less than the same                           ( print page 90769)                        measure of protection afforded the miners under the mandatory standard.                

Song-ae Aromie Noe,

Director, Office of Standards, Regulations, and Variances.
