• Coal Stockpiles. EFCI maintains open stockpiles for raw and clean coal products <br />in the mine facility area and stockpiles clean coal in windrows at the railroad <br />loadout sites. Stockpile areas are relatively flat and are located well away from <br />undisturbed areas, drainage structures and any topsoil stockpiles. Drainage from <br />stockpile areas is routed to either Sedimentation Ponds 1 or 5 in the mine area or <br />Ponds Li and L2 in the loadout area to provide effective control of any resulting <br />suspended solids. In addition, a coal control berm has been placed on the south <br />side of the tracks as shown on Map 13, to help control the coal material from <br />contaminating areas south of the berm. Maximum permitted capacities of <br />stockpiled coal products at the mine area and loadouts are as follows: <br />- Combined Raw Coal Stockpiles (Mine Area) 7,500 tons <br />- Combined Clean Industrial Coal; and <br />Stoker Coal Stockpiles (Mine Area) 110,000 tons <br />- Combined Clean Coal Stockpiles (Rail Loadouts) 38,000 tons <br />Locations of coal stockpiles are shown on Map 18, Mine Surface Facilities. <br />• Stockpile locations at the loadouts are constrained to the areas bounded by the <br />tracks, perimeter ditches, sedimentation ponds, and topsoil piles within the <br />disturbance area. <br />Fugitive dust emissions from open stockpiles are not a significant problem due to <br />relatively small stockpile size, stockpile locations within draw areas, and residual <br />moisture in the stockpiled coal from processing operations. Because of difficulties <br />in handling fine coal particles and with consideration to potential dust emissions, <br />EFCI minimizes handling of both raw and clean coal products to the extent <br />possible. <br />Any potential dust emissions in the mine area are further limited by the method of <br />reclaiming raw and clean coal from stockpiles. The raw coal stockpile is located <br />over multiple draw points that feed a conveyor in an underground reclaim tunnel. <br />From this reclaim tunnel, coal is transported to the preparation plant by a covered <br />conveyor. Clean coal from the industrial coal stockpiles is also withdrawn through <br />multiple draw points to a reclaim tunnel where it is loaded directly into conventional <br />2.05.3-27 Revised an5iss <br />Minor Revision No. 31 <br />
