West Elk Mine <br />Fresh Water Ponds <br />The design for the fresh water pond FW-lis shown in Exhibit 43 and in Exhibit 44, Design <br />Report. The fresh water pond FW-1 at West Elk Mine is approximately 10 acre-feet in <br />capacity. The proposed fresh water pond FW-2 is also about 10 acre-feet in capacity. <br />FW-1 stores water that is pumped from the North Fork of the Gunnison River. FW-1 supplies <br />raw water for potable use, dust suppression, and the fire suppression system. FW-1 was <br />constructed from suitable site materials and is an engineered earth-fill embankment with 3H to <br />1V sideslopes. The pond is lined with asemi-impermeable clay liner. Pond FW-1 <br />specifications are contained in Exhibit 49. Exhibit 44 contains design considerations and data. <br />FW-2 has not been constructed at this time, and is not planned for this five-year permit term. <br />FW-2 is similar in construction to FW-1. The location of FW-2 is shown in Exhibit 43. The <br />design of FW-2 is contained in Exhibit 44. <br />(5)Topsoil <br />Whenever technically feasible, topsoil and subsoil on sites of proposed surface facilities will <br />be stripped and placed in appropriate stockpiles before any construction occurs. Map 53, Map <br />53A, and Map 53B show the location of West Elk Mine's topsoil and subsoil stockpiles. <br />These stockpiles are appropriately signed and will be maintained according to applicable <br />regulations for the life of the mine or until used for reclamation. Handling of topsoil is more <br />thoroughly discussed in Section 2.05(4). When a topsoil stockpile is expected to remain <br />inactive for more than one year, it is seeded with the permanent or temporary seed mix <br />(described in Section 2.05.4.). This seeding will protect the stockpiles from wind and water <br />erosion. <br />(6)Overburden <br />Because West Elk Mine is an underground mine and not a surface mine, no overburden is <br />removed, handled, or stored. Spoil from developing underground workings is handled as coal <br />mine waste. Therefore, the discussion of refuse disposal in Section 2.05.3(8) also applies to all <br />spoil generated during these developmental activities. <br />(7)Coal Handling Structures <br />At West Elk Mine, coal handling structures consist of belt conveyors, three run-of--mine <br />stacking tubes with an underground conveyor reclaim system, adouble-roller crusher, <br />screening plant, rotary breaker, two silos, a crushed coal stack-tube with an underground <br />conveyor reclaim system, a proposed dozer trap reclaim system, and a railroad loadout <br />facility. Map 53 shows the locations of these coal handling structures. Each facility or group <br />of facilities is described below. <br />Conveyors <br />2.05-41 Revised November 2004 PRIO; Rev.
