azea, as depicted on Map 24. The 6,000 gallon diesel fuel tanks and containment will be removed when no longer needed. Water Tank A 20,000-gallon water tank is proposed to be installed on the east side of the pump house. The tank is of steel construction and will be supported by a newly constmcted 14 x 14 x 1 foot concrete pad. The location of this tank is illustrated on Map 24. The tank and pad will be removed when no longer needed. Surfactant Tank TCC will be moving an existing 8,000 gallon storage tank to a permanent location adjacent to the Electrical Shop. The tank will be supported by a concrete pad approximately 20 x 17 x 1 feet and enclosed in a metal building. The building will be 20 x 17 x 20 feet and tie-in to the existing shop. The building, tank, and pad will be removed when no longer required, and either placed in the portal azea during final reclamation, or moved off-site. Covered Storage Buildings Two storage buildings were constructed at the facilities for dry storage of materials. The east building was constructed next to the 20,000 gallon diesel tank installation. This storage azea is 1 SO x SO x 20 feet. The west dry storage azea will be constructed in the tipple azea with dimensions of 100 x 30 x 20 feet. Both structures aze of metal frame construction with steel siding and a dirt floor covered with 1-foot of roadbase material. The locations of both structures are shown on Map 24. These structures will be removed when no longer needed. Additional Rock Dust Bin • An additional rock dust bin (Rock Dust Bin #2) was constructed next to the existing rock dust bin. The bin is within a previously disturbed azea where the limited site drainage is covered by a Small Area Exemption. Rock Dust Bin #2 is 35.5 feet high and has a capacity of 11,000 cubic feet. The foundation is a 22 x 24 x I foot steel- reinforced concrete slab extending 6 feet below grade. Four steel I-beam pillazs support the bin. The location of this rock dust bin is shown on Map 24. This additional rock dust bin and pad will be removed when no longer needed. Coal Handling Svstem The original coal handling system, as shown on Map 24 (Sheet 1/3), Surface Facilities and Freshwater Systems, was designed to handle a maximum production rate of 750,000 tons per year. The system originally consisted of two conveyors, a transfer building and a stacking tube. The slope conveyor (BC-101) tames coal from the underground mine workings to the surface. The original design capacity of this conveyor was 600 tons per hour, based on a dual 150 H.P. Dowty drive and maximum length. A hydraulic take-up is used to maintain adequate belt tension. The Slope Conveyor (BC-101) discharges to the storage pile feeder belt (BC-102) at a transfer station. A flop-gate in the BC-101 dischazge chute allows coal or mine development rock to bypass BC-102 and be dischazged to a stacking conveyor. A stationary magnetic separator located over the BC-101 head pulley removes tramp iron from the coal stream. The magnet is moved from its operating position to dump any collected tramp iron. Conveyor BC-102 dischazges to a steel stacking tube which forms a open conical storage pile. The original design capacity of BC-102 was 1,200 tons per hour, however, coal throughput is primarily a function of how much coal the slope conveyor can deliver. In addition, the crushing, tipple, and loadout coal handling facilities in the Tipple 2 area, which were constructed to serve the previous surface mining operations, were tmnsfen•ed to TCC, and TCC is now responsible for ongoing • maintenance, pemtit compliance and final reclamation of these facilities. These facilities were permitted by Colorado Yampa Coal Company under Permit C-81-071. Design and certification information for these facilities, as shown on the Surface Facilities Map, Map 24, was transferred from Permit C-81-071 and incorporated into TCC's permit (the explosives bunker located to the south of the tipple facility was also transferred to TCC).
