L.• <br />~ Topsoil Storage Piles 2 and 3 will be located 1/4 mile uphill of the base facilities <br />on a gently sloping ridge. The piles are expected to be from 10 to 60 feet high <br />with side slopes of about 2H:1V. <br />• A covered downhill conveyor about 3,200 feet long will be constructed partially <br />on grade and partly elevated (at the south end), along with a new electrical <br />powerline that will be generally parallel to the conveyor to service the mine <br />facilities above. The at grade portion of [he conveyor is presently planned to be <br />founded on intermediate supports spanning 12 to 30 feet. Structural loads are <br />expected to be light to moderate. Elevated conveyor sections will vary in span <br />length from 60 feet to 150 feet and will be supported on steel bents. We assume <br />the powerline will be overhead, on wooden poles. Spurs from the haul road will <br />provide access to the conveyor. Presumably the spurs will be graded, but un- <br />paved dirt roads. <br />• A crusher bench will be located at elevation 6,760 feet, with a 30 by 65-foot <br />screen and crusher building to process sorted coal and a transfer conveyor up <br />to the breaker bench at elevation 6,800 feet. The bench will require cuts and <br />Fills of up to about 15 feet. <br />• The breaker bench will house the process of sorting coal and gob (not coal). <br />Facilities will include a 30 by 65-foot rotary breaker building, material storage <br />pads, a small sewage treatment plant, shop and warehouse building An uphill <br />rock conveyor and downhill reclaim conveyor enter the breaker bench from the <br />next level uphill. The bench will require cuts and fills of about 20 feet. <br />• The coal stockpile bench will be the next uphill level, at about elevation 6,840 <br />feet. A rock pile deposited by the rock conveyor from the breaker bench will be <br />located west of the coal stockpile, which will overlie a reclahn tunnel to transfer <br />coal from the stacking tube and stockpile conveyor down to the reclaim <br />conveyor. The bench may require cuts and fills of up to 50 feet. <br />• The portal bench, with an electrical substation, fueling station, offices, portal <br />and gob conveyors, transfer building and parking will serve the mine entry <br />facilities. The bench may require cuts of 80 feet and fills of up to 50 feet. <br />• Above the portal bench, an air intake shaft pad with a water tank and return <br />air shaft pad with a vent fan are planned, each with cuts and fills of about 10 <br />to 30 feet. The water tank is presumed to be steel or concrete. <br />I I` • 3 <br />
