Once the facility is no longer required, the tanks will be removed and either re -used or cleaned and disposed of <br />The concrete pad will be broken up and the concrete debris placed in the portal area and covered during final <br />• reclamation. <br />Material Disposal Area <br />A solidified waste disposal area is proposed near the low- quality coal stockpile. Materials to be buried in this area <br />would be comprised primarily of hydrocarbon contaminated materials (such as floor -dri) which are non - hazardous <br />and are solidified by mixing with cement. The solidified waste would be buried in the old spoils on the east storage <br />pad (above the dry storage building) as shown on Map 24. Spoil material would be excavated to a depth of 5 -10 <br />feet, and would be set to the side until the solidified material had been placed into the excavation. The excess spoil <br />material would then be used to backfill the remaining void and cap the solidified material. Any extra spoil material <br />will either be stockpiled or spread across the pad area. Placement of the solidified material would likely progress <br />along the pad from east to west, with placement occurring over a number of episodes. Once the area has been <br />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 Buildiu 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 />20,000 Gallon Diesel Tank Installation <br />A 20,000 gallon diesel tank is proposed to be installed on the east end of the materials storage area south of the <br />warehouse. The tank has double walled steel construction for containment. A 28' x 16' x 1.5' steel reinforced <br />concrete pad will be constructed to support the tank. The location of this tank is illustrated on Map 24. The tank and pad will <br />be removed when no longer needed. <br />Bulk Storage Tank Rearrangement <br />The 8,008 gallon hydraulic oil tank and two 6,000 gallon diesel fuel tanks located on the east side of the mule barn <br />are being removed. One of the 6,000 gallon tanks and a steel containment structure will be moved to the tipple <br />area. This will provide a fueling location for equipment on the west side of the surface facilities. The tank and <br />containment will be placed at the top of the slope just east of the stoker oil tank as depicted on Map 24. The other <br />6,000 gallon tank and steel containment structure will be moved to the site north of the solidified waste disposal <br />• area, as depicted on Map 24. The 6,000 gallon diesel fuel tanks and containment will be removed when no longer <br />needed. <br />MR09 -238 2.05 -22 06/29/2009 <br />
