Construction of the overland belt required routing the belt over a part of Pond D and along and on portions of Haul <br />Road B. Colorado Yampa Coal Company previously permitted Haulroad B, and TCC has assumed responsibility <br />for the road. hi the area of Pond D, and where the belt crosses Haul Road B, a crossing has been pemritted and <br />maybe constructed in the future to allow light-duty vehicles to pass over the top of the belt and to provide a game <br />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 for 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 into the surrounding area and topsoiled. <br />A small volume of topsoil remained in an area where the conveyor corridor crossed Haul Road B. This material <br />was salvaged to an approximate depth of 24 inches, windrowed to the edge of the belt corridor, and stabilized with <br />the 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 su~cial concrete structures will be broken-up and removed, and the piers will remain <br />in place, with backfill to be placed over the area. <br />Coal Preparation Plant <br />TCC constructed a preparation plant building, thickener tank and refuse bin as part of an overall prepazation plant <br />facility construction project in 1994/1995 to wash existing low-quality coal stockpiled in the Low Quality Coal <br />Stockpile and low-quality coal produced as a result of ongoing mining operations. The Low-Quality Coal Stockpile is <br />traversed along the northwest by a haul road. Ramps may be constructed along the southeast and southwest perimeters <br />of the pile at the spoiUcoal interface, as necessary, to move material to the plant. The Coa] Prepazation Plant and <br />associated support facilities were constructed adjacent to the overland conveyor in the azea between existing Pond E <br />and the existing Low-Quality Coal Stockpile as shown on Map 24. These structures are located within a previously <br />disturbed area and drainage from the area passes through the existing sediment control system. <br />Site preparation and grading activities for the Coal Preparation Plant 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 azeas for installation of the preparation plant feed hoppers and <br />transfer conveyors <br />• Grading to establish access and flat areas for construction of the preparation plant, thickener, intermediate feed <br />point, and clean and stoker coal stockpiles on the north side of the overland conveyor <br />TR06-53 2.05-28 06/20/06 <br />
