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 Superceded by TR07-59 for Washplant In) <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 /> TRI 8-91 2.05-28 08/20/18 <br />
