SUPPLEMENTAL 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 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 modifications.
II. Petitions for Modification

Docket Number: M2007061C.

[[Page 65077]]

Petitioner: D & R Coal Company, P.O. Box 728, Barbourville, Kentucky 40906.

Mine: Mine 3, MSHA I.D. No. 1519018, located in Knox County, Kentucky.

Regulation Affected: 30 CFR 75.342 (Methane monitors).

Modification Request: The petitioner requests a modification of the existing standard to permit the use of handheld continuousduty methane and oxygen indicators in lieu of machinemounted methane monitors on threewheel tractors with drag bottom buckets. The petitioner states that: (1) All persons will be qualified to use the handheld detectors; (2) a gas test will be taken to determine if any methane concentration is present in the atmosphere prior to allowing the coalloading tractor in the face area and air quality will be monitored by the handheld detector during each trip; (3) if one percent (1%) of methane is detected, the operator will manually de energize his/her battery operated tractor immediately, production will immediately cease, work will be performed to eliminate the elevated methane levels, and production will resume when the methane has been lowered to less than one percent; (4) a spare continuousduty handheld methane and oxygen detector will be available to ensure that all coal hauling tractors are equipped with a working detector; and (5) the monitors will be inspected daily and fully charged, calibrated at least every 30 days, and will not be changed from manufacturer's specifications unless by a person qualified to do so. The petitioner asserts that application of the existing standard reduces protection and the proposed alternative method would greatly increase the safety and well being of miners.

Docket Number: M2007062C.

Petitioner: D & R Coal Company, Inc., P.O. Box 728, Barbourville, Kentucky 40906.

Mine: Mine 3, MSHA I.D. No. 1519018, located in Knox County, Kentucky.

Regulation Affected: 30 CFR 75.380(f)(4) (Escapeways; bituminous and lignite mines).

Modification Request: The petitioner requests a modification of the existing to permit an alternative method for the use of mobile equipment traveling in the primary escapeway. The petitioner asserts that technology has not developed a fire suppression system that will fit on the type of equipment used in this mine, which is operated in the Blue Gem Seam of coal and has seam averaging 24 to 25 inches. The petitioner proposes to use portable fire suppression equipment on threewheel tractors in lieu of installing fire suppression systems. The petitioner proposes to use one twenty or two ten pound portable chemical fire extinguishers on each Mescher tractor used at the mine. If two extinguishers are used, a ten pound extinguisher will be mounted in the operators' deck with the other mounted on the tractor accessible to the operator. If one extinguisher is used, it will be mounted in the operators' deck. In either case, the petitioner proposes to use a total of twenty pounds of fire extinguisher capability on each Mescher tractor, which will be readily available to the operator. The petitioner states that: (1) The fire hazard potential on a Mescher tractor is extremely low because no hydraulics are used on these machines; (2) all other components of the tractor are permissible and are not susceptible to fire hazard; (3) the equipment operator will inspect each fire extinguisher daily before entering the primary escapeway; (4) a record of the inspections will be maintained; and (5) defective fire extinguishers will be replaced prior to entering the mine. The petitioner further states that: (1) The main travelway of the mine is also the primary escapeway; (2) the amount of time each Mescher tractor is in the primary escapeway is limited to the travel time to the face at the start of the shift, at midshift, to change batteries, and to travel out at the end of the shift during which time the drag bucket is empty and the tractor is not transporting coal; (3) portable fire suppression equipment can be used to direct the chemical fire suppressant by the operator in a more effective manner in case there is a fire; and (4) in this low coal mine the small fire extinguishers would be more effective to extinguish a fire than the machinemounted systems. The petitioner also states that application of the existing standard will reduce the safety of the affected miners, since fire suppression equipment is not presently available for this type of equipment and currently, technology does not provide fire suppression equipment for the type of machinery used at the mine. The petitioner asserts that the proposed alternative method would provide at least the same measure of protection as the existing standard.

Docket Number: M2007063C.

Petitioner: Alden Resources, LLC, 332 W. Cumberland Gap Parkway, Suite 100, Corbin, Kentucky 40701.

Mine: Bain Branch Refuse Piles (I.D. No. 1211KY70715701), MSHA I.D. No. 1517691, located in Whitley County, Kentucky.

Regulation Affected: 30 CFR 77.214(a) (Refuse piles; general).

Modification Request: The petitioner requests a modification of the existing standard because: (1) The proposed refuse pile is constructed over abandoned underground mine openings in the Blue Gem coal bed; (2) the abandoned openings have been sealed and backfilled with dirt; and (3) the abandoned pit is a ``boxcut'' and the refuse will be placed in 2foot lifts and used to reclaim the pit to approximately the original contour. The petitioner states that: (1) The proposed modification will not reduce or diminish the safety of the proposed refuse pile since the pit being reclaimed is a boxcut and the dip of the coal seam is away from the portal area; (2) there is no danger of water from the abandoned workings saturating the fill and causing a failure; and (3) modification of the standard will allow for safe disposal of coal refuse at this site and will allow mining to continue in the area. The petitioner asserts that the proposed alternative method would provide at least the same measure of protection as the existing standard.

Docket Number: M2007064C.

Petitioner: P & A Engineers and Consultants, Inc., for Stirrat Coal Company, P.O. Box 279, Louisa, Kentucky 41230.

Preparation Plant, MSHA I.D. No. 4602515, located in Logan County, West Virginia.

Regulation Affected: 30 CFR 77.214(a) (Refuse piles; general).

Modification Request: The petitioner requests a modification of the existing standard to permit a dry refuse structure to be added to the existing plant and rescue facility located near Stirrat in Logan County, West Virginia. The petitioner states that: (1) The mine (Williamson Seam) was faced up using the conventional method of creating two mine benches and two highwalls for the mine entries; (2) it is estimated that mining was completed in Mid1988; (3) the mine seals were certified by Registered Professional Engineer on September 20, 1988; and (4) upon completion of mining the portals were sealed and the highwalls were returned to an approximate 2:1 slope; and (5) a 6 inch Interior Diameter (ID) steel drain was installed eliminating any potential head of water on the mine seals. The petitioner has provided with this petition a photo of the installed drain pipe and the backfilled portals. The petitioner further states that: (1) The existing drain pipe will be routed to the outside and beyond the limits of the
[[Page 65078]]
coarse refuse fill; and (2) a rock filter will be placed around the extended pipe and wrapped in filter fabric (Mirafi 140N or equivalent) and extended through the refuse pile. The petitioner asserts that the proposed alternative method would provide at least the same measure of protection as the existing standard.

Docket Number: M2007065C.

Petitioner: R S & W Coal Company, 207 Creek Road, Klingerstown, Pennsylvania 17941.

Mine: R S & W Drift Mine, MSHA I.D. No. 3601818, located Schuylkill County, Pennsylvania.

Regulation Affected: 30 CFR 75.311(a) (Main mine fan operation).

Modification Request: The petitioner requests a modification of the existing standard to allow the main mine fan to be idle during non working hours. The petitioner states that historically, the main mine fan operation has been shut down during nonworking shifts, because of icing during the winter months. The petitioner proposes to use the following stipulations in the fan stoppage plan: (1) Shut the main mine fan down during idle periods; (2) no mechanized equipment will be used underground; (3) no electric power circuits enter the underground mine; (4) the main mine fan will be operated for a minimum of onehalf hour after the pressure recorder indicates that the normal mine ventilating pressure has been reached prior to any one entering the mine; (5) the mine battery locomotive may be used to make the required preshift examination; (6) the communication circuit 9volts will be energized prior to the preshift being made;
(7) a certified person will conduct an examination of the entire mine according to the requirements in 30 CFR 75.360; (8) persons will be allowed to enter the mine after it is determined to be safe and the preshift examination results have been recorded. The petitioner further states that the gangway, chutes, and headings are developed in rock and tests have shown that measurements taken every three seconds at the main mine fan found no detectable methane concentrations. The petitioner asserts that the proposed alternative method would provide at least the same measure of protection as the existing standard.
