utilized to the fullest extent possible, the area will have any piled excess spoil material remaining pushed out and <br />• leveled. The pad will. be buried by spoil material during final reclamation operations for the portal area, and should <br />not be subject to re- disturbance. The disposal area lies below the approved post - mining topography, and is located <br />out of groundwater zones. <br />Coal Mine Waste Disposal Area <br />A coal mine waste disposal area is proposed at the existing storage pad south of the low- quality coal stockpile. <br />Materials to be buried in this area would be comprised of solid coal mine waste material. Spoil material would be <br />excavated to a depth of 5 -10 feet, and would be stored on the pad until the waste material had been placed in the <br />excavation. The spoil material would then be used to backfill the remaining void and cap the waste material. Any <br />excess spoil material would either be stockpiled or spread across the pad area. The pad will be buried by spoil <br />material during final reclamation operations for the portal area, and should not be subject to re- disturbance. The <br />disposal area lies below the approved post - mining topography, and is located out of groundwater zones. <br />Coal Analysis Laboratory Building and Preparation Facility <br />TCC is installing two trailers to provide in -house coal analysis east of the prep plant. The trailers will have <br />maximum dimensions of 15' x 70' x 14'. The coal preparation trailer will sit on a partial pad (mesh- reinforced) <br />with dimensions of 15' x 20' x 0.5'. Each trailer may have as many as eight 12" diameter four -foot long cylindrical <br />footers for support. The doors of the trailers will be connected by a 3' wide, 60' long sidewalk. <br />Fueling Storage and Fueling Installations (MR10 -246) <br />Four fueling installations, located as shown on the Surface Facilities Map (Map 24), allow fueling of gasoline and <br />• diesel equipment in proximity to specific working areas. The following summarizes the location and equipment <br />currently located at each fueling installation: <br />Gasoline Storage Tank and Fueling Installation — Located in Storage Yard north of Mine Office/Bathhouse <br />Facility. 2,000 gallon double -wall steel gasoline tank and 12,000 gallon steel magnesium chloride (dust <br />control agent) tank on reinforced concrete slab foundations (2 — 10' x 30' x 1') with protective steel posts <br />on traffic side. Gasoline pump with electrical control box. <br />Main Diesel Storage Tank and Fueling Installation — Located adjacent to Dry Storage Shed, directly across <br />and south of the Mine Shop/Warehouse Facility. 20,000 gallon double - walled tank on reinforced concrete <br />slab foundation (28' x 16' x 15) with protective steel post on traffic side. Diesel pump with electrical <br />control box. <br />3. Run -of -Mine (ROM) Stockpile Diesel Storage Tank and Fueling Installation — Located southwest of ROM <br />Stockpile, adjacent to the new access road for the Coal Refuse Disposal Area (CRDA) Expansion. . 10,000 <br />gallon double - walled tank within 20' x 16' welded steel containment box with sidewalls, with protective <br />steel post on traffic side. Diesel pump with electrical control box. <br />4. Belt- Out -Back (BOB) Area Diesel Storage Tanks and Fueling Installation — Located on the east side of the <br />BOB Facilities Area, adjacent to the Pond A and Explosives Storage access road. Two, 8,000 gallon steel <br />diesel tanks within 25' x 20' welded steel containment box with sidewalls and steel post and canopy cover. <br />Diesel pump with electrical control box. <br />TC proposes to upgrade the existing fuel storage and fueling installations. Upgrades will involve; 1) Excavation of <br />an incised spill catchment basin at each location, segregation and shipment off -site for treatment (land - farming) of <br />any petroleum - contaminated materials, and movement of any non - contaminated material to either the CRDA or the <br />permitted overburden stockpile area; 2) Preparation of the basin areas (will typically involve over - excavation and <br />• re- compaction of the materials); 3) Placement of either concrete (installations 1 and 2, above) or HDPE liners <br />(installations 3 and 4, above) for the spill catchment basins. Where HDPE is used as a liner, the liner will be <br />protected by a sand cover and crushed stone fill, and drain piping will be installed to carry any spillage and water <br />accumulations to an oil/water separator; 4) Grading of the modified fuel storage and fueling installations to assure <br />MR 10 -246 2.05 -22 08/17/2010 <br />
