• 2.05.3 form the boundary of the pile, and creating a'borrow area' in the footprint of the Gob pile in order to increase the cover material available for reclamation (approved by TR -43). Once this 'borrow area' was complete, the Operator applied to the DRMS to place Gob in the footprint of the pile (TR -44) and upon approval from the Division, the Operator began placing gob in the second quarter of 2007, in 50 foot benches to a maximum height of 150 feet. At the time of this writing (9/2009), the pile is nearly full. Topsoil and coverfill material that is salvaged during the site preparation will be placed in the existing piles. 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. (3)(a) Following is a discussion of the proposed mine facilities: Portal Conveyor Transfer Buildings The D -Seam portal conveyor transfer building is a structural steel building where the main belt from the mine terminates. The coal from the mine will transfer to the stockpile conveyor. Gob conveyed from the mine will be transferred to the gob belt. The dimensions of the building are approximately 20 feet by 24 feet by 45 feet high. The 13- Seam will have a similar transfer building. Gob conveyed from the B -Seam will be transferred via a steel chute to a concrete gob bin. Coal conveyed from the B -Seam is transferred to the uphill conveyor. Stacking Tube The raw coal is stacked by this concrete tube to minimize coal segregation and air particulate emissions. The tube is approximately 85 -feet high and 12 -feet in diameter. It has 4 foot openings to allow coal to flow from the tube to the stockpile area. The stacking tube is located directly on the reclaim tunnel. Reclaim Tunnel The reclaim tunnel is located under the stacking tube and a 70,000 ton stockpile. It is of reinforced concrete construction. The typical inside dimensions of the tunnel are 13 feet high by 12 feet wide. The tunnel is approximately 245 feet long. A 36 -inch diameter escape tube is located on the east end of the tunnel. The 120 foot long escape tube terminates at a concrete fan housing that is approximately 6 feet by 6 feet by 8 feet high. • TR -64 2.05-9- 09/09 APPK6VE,b . - z1Z�/o9 -
