material, or spoil, were mixed with or substituted for any stockpiled <br />surface soils. Topsoil is stored in protected stockpiles because it <br />is not practical to redistribute it or use it elsewhere immediately. <br />The locations of the stockpiles are shown on Drawings D-2-2 and D-2-3. <br />The soil was picked up with self-propelled rubber tire scrapers and <br />put down immediately in the stockpiles. Compaction due to repeated <br />passes with equipment was avoided. Stockpile areas are marked with <br />signs and checked periodically to ensure their continued protection. <br />Detailed treatment of stockpile protection and maintenance is given in <br />the Interim Reclamation Plan. <br />4.3.2.6 Coal and Non-Coal Processing Waste <br />Coal Processing Waste <br />The loadout facility involves no coal preparation or crushing. Small <br />amounts of coal dust generated at the dump site which may escape the <br />washdown treatment are collected in a catch basin below, the hopper and <br />carried by the conveyor tube to the evaporation pond. At the unit- <br />train loading point, coal wastes are collected in the evaporation pond <br />immediately adjacent to the surge bin. The accumulated sediment <br />within the pond is routinely removed and disposed of at the mine <br />refuse disposal area. <br />Noncoal Wastes <br />Any flammable liquids or other combustibles are placed in a controlled <br />area designated as the equipment building on D-2-2. No leachate or <br />surface runoff reaches these materials; the risk to surface and ground <br />water is negligible. Fire hazards are strictly controlled, as <br />detailed in MSHA permit requirements. Domestic waste is hauled to an <br />approved trash dump and not allowed to accumulate at the loadout <br />facility. Subsoils removed from the pond excavation and the truck dump <br />site were used as part of the rail spur bed material. <br />4-40 <br />
