loaded from the ROM stockpile with a loader or similar type of equipment and hauled to Tipple 2 using the existing <br />haul road ( Haulroad B -1). <br />Construction of the overland belt required routing the belt over a part of Pond D and along and on portions of <br />Haulroad B. Colorado Yampa Coal Company previously permitted Haulroad B, and TCC has assumed <br />responsibility for the road. In the area of Pond D, and where the belt crosses Haulroad B, a crossing has been <br />permitted and may be constructed in the future to allow light -duty vehicles to pass over the top of the belt and to <br />provide a game crossing. <br />The overland belt is of typical construction, as shown on Figure 19, Overland Belt Profile, and a partial enclosure <br />over the length of the beltline offers safety protection from the moving belt and rollers as well as dust control. <br />Footers for the belt structure were constructed on 10 -foot centers for the length of the belt. An access road parallel <br />to the beltline extends along most of the belt corridor to provide access for periodic belt maintenance. In addition, a <br />small concrete pad was installed beneath the beltline near the Tipple to facilitate access and equipment placement <br />for belt splicing. This pad will be broken -up and buried during final reclamation of the Tipple area. <br />To accommodate required placement of footers through the Pond D emergency spillway and across the crest and <br />face of the Pond D embankment, fill material was brought in and placed and compacted on the embankment face to <br />provide a level work area for the drill -rig used to drill holes for the footers. A qualified Registered Professional <br />Engineer supervised this work and certified that fill placement would not impact embankment stability. When the <br />site is reclaimed the fill will be graded and blended into surrounding areas and topsoiled. <br />A small volume of topsoil remained in an area where the conveyor corridor crossed Haulroad B. This material was <br />salvaged to an approximate depth of 24 inches, windrowed to the edge of the belt corridor, and stabilized with the <br />appropriate seed mixture. Approximately 100 CY of topsoil was salvaged and stockpiled. When the site is <br />reclaimed, this material will be redistributed over the site and reseeded with the appropriate seed mixture. As <br />shown on Map 24, a silt fence, or other Alternative Sediment Controls, is used downslope of the disturbance to <br />control runoff and sediment under a Small Area Exemption. <br />A drive building was constructed adjacent to the existing crusher building to house the drives for the overland belt. <br />The building is approximately 28 x 40 feet and is built on a 5 x 28 x 40 foot concrete foundation. A control <br />building (MCC -2) is located adjacent to the drive building, as shown on Map 24. The building is constructed on a <br />concrete pad approximately 6 inches thick and a 10 -inch x 4 -foot stem wall, which sits on 8 piers approximately <br />20 -25 feet deep and 10 -12 inches in diameter. After the building is no longer required, it will be removed during <br />the reclamation phase. The surficial concrete structures will be broken -up and removed, the piers will remain in <br />place, and backfill will be placed over the area. <br />Coal Washplant (Washplant I, Modified and Suaerceded by TR07 -59 for Washulant II)) <br />TCC constructed a coal washplant building, thickener tank and refuse bin as part of an overall washplant facility <br />construction project in 1994/1995 to wash existing low- quality coal stockpiled in the Low Quality Coal Stockpile and <br />produced as a result of ongoing mining operations. The Low - Quality Coal Stockpile is traversed along the northwest <br />by a haulroad. Ramps may be constructed along the southeast and southwest perimeters of the pile at the spoil /coal <br />interface, as necessary, to move material to the plant. The Coal Washplant and associated support facilities were <br />constructed adjacent to the overland conveyor in the area between existing Pond E and the existing Low - Quality Coal <br />Stockpile as shown on Map 24. These structures are located within a previously disturbed area, and drainage from <br />the area passes through the existing sediment control system. <br />Site preparation and grading activities for the Coal Washplant involved the following activities: <br />• Placement of a culvert in Ditch D -3 on the south side of the overland conveyor <br />• Grading to establish effective access and flat areas for installation of the preparation plant feed hoppers and <br />transfer conveyors <br />TR07 -59 <br />2.05 -28 <br />02/27/07 <br />
