2.05.3 4. Benches The proposed surface disturbance for the upper mine facilities includes the construction of benches with related access roads. The first or upper is a utility bench for a water tank, electrical substation and ventilation shaft and two fans. The second bench or D-Seam portal bench is developed for an office, change house, shop, warehouse, screen and crusher building, coal stockpile, reclaim tunnel, radial stackers and other facilities. Portions of the portal bench will be utilized for material storage and other mine facilities that are discussed in section 2.05.3(3). A small bench along the haul road was constructed for the downhill conveyor transfer and drive building. The B-Seam portal bench was developed during 2003 for mine entries, portal conveyor, transfer tower and other facilities. Another bench was constructed along old State Highway 133 for the coal stockpile, reclaim system and truck loadout. The Hubbard Creek shaft will have a bench constructed in 2007. The proposed construction site is located immediatelywest of the Hubbard Creek Road approximately three tenths of a mile north of the USDA-FS boundary. The Hubbard Creek shaft pad was strewn with large sandstone boulders. These boulders were mechanically broken into --24" minus rocks. Some of the rocks were used on site to stabilize cut and fill slopes. Some were taken to a temporary rock storage area near Freeman Gulch. The remaining rocks, approximately 3,000 cubic yards, will be hauled to the Bowie No. 1 East Mine reclamation project. Based on the Operators knowledge of geology in the area, sandstone isnon-toxic and non acid forming. • 5. Gob Piles A gob pile was constructed east of the mine entrance below the old King Mine portals beginning at the level of the old railroad track grade. The disturbance associated with the gob pile includes clearing the area necessary to form the boundary of the pile. Facilities associated with the gob pile include a topsoil stockpile, cover fill stockpile, haul road and a sediment pond. The new gob pile was constructed during 2004. It is located approximately 1,500-feet east of the existing gob pile. Facilities associated with the new gob pile include a topsoil stockpile, cover fill stockpile, haul road and a sediment pond. 6. Unit Train Loadout The disturbance associated with the unit train loadout is located south of the mine along the Union Pacific mainline. A conveyor, new track and a batch weigh system were installed. Approximately 2,800 feet of mainline was relocated so the lead and parallel storage track could be constructed. The lead track is 8,240 feet long and the storage track is 3,570 feet long. (3) Mine Facilities The major surface facilities are located north of the North Fork of the Gunnison River. The D-Seam mine portals are located about 800 feet above old State Highway 133 at an elevation of approximately 6880 feet where the D-2 Seam outcrops. The B-Seam mine portals will be located about 550 feet above old State Highway 133 at an elevation of approximately 6630 feet. The loadout is located along the mainline of the Union Pacific Railroad at an elevation of approximately 5880 feet. The surface facilities consist of sediment control structures, coal handling facilities, unit train loadout, support facilities for mine operations and other related facilities.
