Serlian - 2.05.3 <br />loadout transfer conveyor. The silo provides approximately 8,000 tons of live <br />• storage capacity. Additional details on coal handling facilities are provided in the <br />subsequent coal handling section. <br />G. Coal Sampling System - A coal sampling system on the batch-weight trarufer <br />conveyor periodically collects a coal sample from the trarufer conveyor for quality <br />control purposes. The sampling system and associated ancillary equipment are <br />contained in a small metal building. Additional details on the coal handling facilities <br />are provided in the subsequent coal handling section. <br />H Temporary Coal Mme Wazte Storage Area - A temporary storage area has been <br />established for interim storage of up to 1,500 tons of coal mine waste. This <br />temporary storage area will be used in the event that coal mine waste disposal areaz <br />are not accessible due to weather related or other factors. Additional details on <br />waste handling, storage and disposal are provided in subsequent coal mine waste <br />section. <br />I. Batch Weigh Train Loadout and Transfer Conveyor -Coal was previously loaded to <br />unit trains through a discharge chute in the base of the coal storage silo. In <br />conjunction with the 1995-2000 mine expansion, the train loading system was <br />modified to provide more system flexibility and allow fazter train loading, consistent <br />with increazed mine production rates. The primary modificatioru involved <br />installation of a transfer conveyor in the baze of the existing silo and corutnrction of <br />a batch weigh loadout on an adjacent side-track The system modifications are <br />designed to allow loading at a maximum rate of 6,000 tons per hour. The new batch <br />weigh loadout is housed in an enclosed steel building and consists of a surge bin, <br />• batch weigh bin, telescoping loading chute, and associated control and ancillary <br />equipment. Additional details on coal handling systems are provided in the <br />subsequent coal handling section. <br />East Yana Refuse Pile -The Eazt Yard refuse pile u the active disposal area for coal <br />mine waste rock It is located near the sealed GSeam portak. This disposal area is <br />nearlyfull and will be replaced by the new West Valley Fill coal mine waste pile. The <br />existing East Yard refuse pile reached capacity in 1998. Removal, however, of a <br />portion of the pile az fill for the Elk Creek coal stockpile pad opened up some <br />additional capacitythat can be rued for future coal refuse disposal. Additional details <br />on coal mine reface handling, storage and disposal are provided in subsequent coal <br />refuse handling section. <br />K. West Valley Coal Refuse Pile -The West Valley coal refuse pile site was selected and <br />developed az a replacement for the East Yard pile for future refuse disposal. The <br />West Valley refuse pile, located in the fast ephemeral drainage west of Elk Creek, is <br />designed with a disposal capacity of approximately 120,000 cubic yards to <br />accommodate anticipated future operations. The West Valley site incorporates <br />upgradient clean water diversions, perimeter drainage collection ditches, a rack <br />underdrain, and a sedimentation pond, to provide for effective drainage control. <br />Additional details on coal refuse handling, storage and disposal are provided in <br />subsequent coal mine wazte handling section. <br />L. Main Haul Road -The main haul road u a partially paved and gravel-surfaced road <br />which connects the Ells Creek facilities area to State Htghway 133. This road <br />• provides virtually the only access to thu Area. Haul trucks that haul coal to and <br />from the facilities utilize this road. The haul road extends from State Highway 133 <br />to the coal stockpile areas and to the truck scales and dump station. The road <br />extends from the west side of the dump station and circles back to the east, around <br />PR04 2.05-14 Revised August 2000 <br />
