CHAPTERTWO Alternatives <br />2.10.6 Associated Surface Facilities <br />Surface <br />A number of surface facilities are proposed to support the mining operation, including but not <br />limited to a ventilation fan, office, shop, sewage plant, and raw coal stockpile. These facilities <br />would be located on the existing and proposed coal leases. It is also proposed to locate surface <br />facilities on unleased BLM-managed lands for which aland-use permit will be required. CAM <br />submitted a Land Use Application and Permit dated February 10, 2006 to BLM for facilities to <br />be located on BLM-managed lands. These facilities include but are not limited to a 12-foot-wide <br />maintenance road, 20- to 24-foot-wide access road, water pipeline, conveyors, overhead power <br />lines, coal waste disposal area, coal stockpiles, unit train loadout, and a coal preparation plant. <br />Additionally, two-quadrant automatic gate systems would be installed at the two railroad/county <br />road crossings. A package sewage treatment plant would be constructed utilizing settling tanks, <br />chlorine treatment, and an active aeration system. Any sludge generated would be hauled off site <br />and disposed of in accordance with local and state ordinances. Treated water would be <br />discharged to a sedimentation pond and eventually into surface drainage. <br />Coal Operations <br />Coal operations are depicted in Figure 2-ll, Coal Operations Sequence. The coal would be <br />transported from within the mine via a portal conveyor. The portal conveyor is an extension of <br />the conveyor from within the mine. It would be 72 inches wide and extend from the portal to the <br />portal transfer building. A 48-inch-wide refuse (non-coal waste rock) belt would convey refuse <br />from the portal transfer building to a temporary gob (waste rock) pile. A 72-inch-wide stockpile <br />conveyor would then transfer coal from the portal transfer tower to the stacking tube and raw <br />coal stockpile. A reclaim conveyor would transfer coal from the coal stockpile to the wash plant. <br />A 48-inch-wide clean coal belt would deliver the coal to the stacking tubes and clean coal <br />loadout stockpile. A 72-inch-wide loadout belt would feed coal to the unit train loadout. A <br />48-inch-wide refuse belt would send waste rock to the gob bin and coal mine waste disposal <br />area. <br />The portal transfer building would be a structural steel building approximately 20 feet by 24 feet <br />by 45 feet high, where the main belt from the mine terminates. The coal from the mine would be <br />transferred via a stockpile conveyor. Refuse from the mine would be transferred onto the gob <br />belt. <br />Coal would be stored in one of two open stockpiles: run-of--mine or clean coal. Up to <br />300,000 tons of mixed coal and rock would be stored in the run-of--mine pile; located within the <br />coal lease boundary. The clean coal stockpile would be located near the unit train loadout. Up <br />to 350,000 tons of coal would be stored in the clean coal stockpile. Stacking tubes would also be <br />used to transfer coal into stockpiles, to minimize coal size segregation and air particulate <br />emissions. Stacking tubes would be 80 to 100 feet high and 10 to 12 feet in diameter. They have <br />numerous, evenly spaced 4-foot-square openings to allow coal to flow from the tube to the <br />stockpiles. <br />Coal from the run-of--mine stockpile would be transferred to the coal preparation, or coal wash, <br />plant. The preparation plant would be a structural steel building where coal and rock are <br />2-49 <br />
