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.

Docket Number: M-2012-095-C.
Petioner: Bledsoe Coal Corporation, Route 2008, Box 351A, Big Laurel, Kentucky 40808.
Mine: Mine No. 4, MSHA I.D. No. 15-11065, located in Leslie County, Kentucky.
Regulation Affected: 30 CFR 77.214(a) (Refuse piles; general).
Modification Request: The petitioner requests a modification of the existing standard for surface areas of underground coal mines to permit the use of refuse material from the BL-1 Preparation Plant to reclaim the face-up area for five portals of Mine No. 4. The portals are located downstream of John Miniard Branch off Greasy Creek. The petitioner states that:
(1) The Mine No. 4 has been abandoned since June 2008, and currently, there is no waterflow from the five portals, although water controls will be constructed so that water could flow from the portals without saturating the fill.
(2) A fireproof barrier of clay or inert material will be constructed 4 feet over the exposed coal seam. Analysis of the material used to construct the fireproof barrier will be provided to verify it as noncombustible. The petitioner proposes to:
(1) Place coarse refuse over abandoned underground mine openings in the Mine No. 4 coal seam during the reclamation of the portals. There are no steam lines associated with this proposal.
(2) Construct Miniard Branch portals coarse refuse fill over the underground mine openings face up located along the mouth of John Miniard Branch at the confluence of Greasy Creek. Five underground openings along the face up will be covered by coarse refuse. All of the openings are located in the Hazard No. 4 coal seam. (The location of each opening is shown on the Plan View map provided with this petition.) The petitioner further states that:
(1) The Hazard No. 4 coal seam in this area was mined from the early 1980's and closed in 2008.
(2) During the life of the mine, two of the portals fell in and sealed the openings (as shown on the Plan View map). Since this area was used mainly for an exhausting fan site, the portals were not cleaned back out.
(3) On closure of the mine, two water pipes were inserted into two different openings and the portals were backfilled 25 feet back into the mine and then 4 feet over the portals. Due to the dip of the coal seam, the water in this area drains to another set of portals that have pipes and water drains to allow the water to exit, and no water has come out at this site.
(4) The petitioner proposes to reclaim this site using coarse refuse over the backfilled portals. To contend with the eventuality that water might exit the mine through these portals, the petitioner will construct a durable rock underdrain across the front of the backfill spanning all the portals.
(5) Two pipes inserted back into the mine will tie into the rock underdrain so that any water seeping through the coarse refuse or coming out of the underground mine will travel through this rock underdrain. The rock underdrain will be constructed of durable rock and wrapped in filter fabric.
(6) On completion of the coarse refuse fill, the fill will be covered with noncombustible materials. Drawings detailing the construction methods used to seal the openings are provided with this petition.

Mine: Troy Mine Inc., MSHA I.D. No. 24-01467, Highway 56 South Asarco Mine Road, Troy, Montana, 59935, located in Lincoln County, Montana.
Regulation Affected: 30 CFR 57.11055 (Inclined escapeways).
Modification Request: The petitioner requests a modification of the existing standard for underground metal and nonmetal mines to permit the use of a 317-foot portion of a designated secondary escapeway that is steel-encased with secure landings and equipped with a leaky feeder communication system. The petition pertains to a secondary escapeway/ raisebore from the Upper C Bed to the Lower Quartzite area. The petitioner states that:
(1) The secondary escapeway/raisebore from the C Bed to the Lower Quartzite area is 42 inches in diameter and steel-encased.
(2) The escapeway/raisebore from the C Bed to the Lower Quartzite area is equipped with a ladder and secure landings at least every 30 feet, which conforms with MSHA's standard for surface travelways in 30 CFR 57.11025.
(3) The secondary escapeway/raisebore from the C Bed to the Lower Quartzite area consists of two sections. The first section is 114 feet beginning at the C Bed and ending at the Upper C Bed. The second section is 317 feet beginning at the Upper C Bed and ending at the Lower Quartzite area.
As an alternative method to the existing standard, the petitioner proposes to:
(1) Install a leaky feeder communication system in the steel- encased secondary escapeway from the C Bed to the Lower Quartzite area to provide the miners in the escapeway with continuous communication with the surface, and allow for notification that personnel are in the raise and on their way out.
(2) Use steel encasement of the escapeway/raisebore to protect the leaky feeder system from damage and protect the miners from exposure to falling rocks in the escapeway.
(3) Configure landings so that they are spaced at a maximum of 30- foot intervals to protect resting miners and prevent them from falling down the escapeway.
(4) Modify the escape and evacuation plan required by 30 CFR 57.11053 to provide for ventilation changes in the event of a fire when using the secondary escapeway, using the following procedures as appropriate:
(a) Reversing the fan direction at the top of the secondary escapeway.
(b) Closing ventilation tubes in the air-walls at the access drifts in each level.
(5) Install radio boxes in the secondary escapeway/raisebore from the C bed to the Lower Quartzite area. The radio boxes will contain several radios, a charging station for the radios, and extra batteries.
(6) Install clear and legible markings at 30-foot intervals denoting the remaining distance to the surface in the secondary escapeway/raisebore.
Within 45 days after the Proposed Decision and Order becomes final, the petitioner will submit proposed revisions to the escape and evacuation plan as required in 30 CFR 57.11053. Within 60 days after the Proposed Decision and Order becomes final, the petitioner will submit proposed revisions for its approved 30 CFR part 48 training plan to the District Manager. In addition to the requirements specified in this petition, the proposed revisions will specify initial and refresher training regarding the terms and conditions stated in the Proposed Decision and Order.
The petitioner further states that the proposed alternative method provides additional protection above and beyond the requirements of the existing standard by allowing miners in the secondary escapeway to know their exact location in the raise, while they are traveling out of the mine. With this information and the radios provided, exact information on miner locations can be communicated to personnel on the surface to aid in emergency evacuation and rescue.
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.
