area, as depicted on Map 24. The 6,000 gallon diesel fuel tanks and containment will be removed when no longer <br />needed. <br />• Water Tank <br />A 20,000-gallon water tank is proposed to be installed on the east side of the pump house. The tank is of steel <br />construction and will be supported by a newly constructed 14 x 14 x 1 foot concrete pad. The location of this tank <br />is illustrated on Map 24. The tank and pad will be removed when no longer needed. <br />Surfactant Tank <br />TCC will be moving an existing 8,000 gallon storage tank to a permanent location adjacent to the Electrical Shop. <br />The tank will be supported by a concrete pad approximately 20 x 17 x 1 feet and enclosed in a metal building. The <br />building will be 20 x 17 x 20 feet and tie-in to the existing shop. <br />The building, tank, and pad will be removed when no longer required, and either placed in the portal area during <br />final reclamation, or moved off-site. <br />Covered Storage Buildings <br />Two storage buildings were constructed at the facilities for dry storage of materials. The east building was <br />wnstmcted next to the 20,000 gallon diesel tank installation. This storage area is 150 x 50 x 20 feet. The west dry <br />storage area will be wnstructed in the tipple area with dimensions of 100 x 30 x 20 feet. Both structures are of <br />metal frame construction with steel siding and a dirt floor covered with 1-foot of roadbase material. The locations <br />of both structures aze shown on Map 24. These structures will be removed when no longer needed. <br />Additional Rock Dust Bin <br />An additional rock dust bin (Rock Dust Bin #2) was constructed next to the existing rock dust bin. The bin is <br />within a previously disturbed area where the limited site drainage is covered by a Small Area Exemption. Rock <br />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 1 foot steel- <br />reinforced concrete slab extending 6 feet below grade. Four steel I-beam pillars support the bin. The location of <br />this rock dust bin is shown on Map 24. This additional rock dust bin and pad will be removed when no longer <br />needed. <br />Coal Handling Svstem (Modified and Suoerceded by TR07-59 for Washplant II) <br />The original coal handling system, as shown on Map 24 (Sheet 1/3), Surface Facilities and Freshwater Systems, <br />was designed to handle a maximum production rate of 750,000 tons per year. The system originally consisted of <br />two conveyors, a transfer building and a stacking tube. The slope conveyor (BC-101) carries coal from the <br />underground mine workings to the surface. The original design capacity of this conveyor was 600 tons per hour, <br />based on a dual 150 H.P. Dowty drive and maximum length. A hydraulic take-up is used to maintain adequate belt <br />tension. The Slope Conveyor (BC-101) discharges to the storage pile feeder belt (BC-102) at a transfer station. A <br />flop-gate in the BC-101 discharge chute allows coal or mine development rock to bypass BC-102 and be discharged <br />to a stacking conveyor. A stationary magnetic separator located over the BC-101 head pulley removes tramp iron <br />from the coal stream. The magnet is moved from its operating position to dump any collected tramp iron. <br />Conveyor BC-102 discharges to a steel stacking tube which forms a open conical storage pile. The original design <br />capacity of BC-102 was 1,200 tons per hour, however, coal throughput is primarily a function of how much coal <br />the slope conveyor can deliver. <br />In addition, the crushing, tipple, and loadout coal handiing facilities in the Tipple 2 area, which were constructed to <br />serve the previous surface mining operations, were transferred to TCC, and TCC is now responsible for ongoing <br />maintenance, permit compliance and final reclamation of these facilities. These facilities were permitted by <br />Colorado Yampa Coal Company under Permit C-81-071. Design and certification information for these facilities, <br />as shown on the Surface Facilities Map, Map 24, was transferred from Permit C-81-071 and incorporated into <br />TCC's permit (the explosives bunker located to the south of the tipple facility was also transferred to TCC). <br />TR07-59 2.05-24 02/27/07 <br />
