stockpiles of sand, gravel, cement, and other materials. The entire batch plant was removed following completion of <br />construction. A washdown water drain -line was constructed from the west side of the Batch -Weigh Loadout <br />• building to Pond C. The drain -line is a PVC pipe mounted on a set of three support poles and sloped to drain. The <br />locations of the support poles are shown on Map 24 under the label "Batch Weigh Drain Line ". <br />The new MCC building was constructed at the location depicted on Map 24. The building is a steel - framed, metal - <br />sheathed building constructed on a concrete foundation. Building dimensions are approximately 20 x 20 x10 feet. <br />The building foundation consists of a 12 -inch thick poured- concrete floor supporting 8 -inch thick, 3 -inch tall <br />poured- concrete stem walls. <br />Site configuration required the Batch -Weigh Coal Stockpile to cover Ditch D -1 along the northern margin of the <br />stockpile for a distance of approximately 440 feet. In this area, Ditch D -1 was routed through a 24 -inch diameter CMP <br />culvert beneath the stockpile or through a combination of culverts providing the same hydraulic conveyance capability. <br />Culvert sizing is based on a revised evaluation of Ditch D -1 design requirements (refer to Exhibit 8). Ditch D -1 was <br />also re- routed slightly to the north as shown on Map 24. The Batch -Weigh Coal Stockpile and surrounding area are <br />graded to slope towards Ditch D -1, which proves perimeter sediment control for the area and routes runoff to Pond <br />D. Temporary diversion ditches upgradient of the Batch -Weigh Coal Stockpile are designed and constructed to <br />intercept overland flows and convey water away from the coal stockpile area and into Ditch D -1. The temporary <br />ditches are designed according to the specifications presented in Exhibit 8. Temporary sediment control measures <br />consisting of silt fences and or berms were installed down - gradient from the construction site during construction, as <br />appropriate until permanent drainage control was established. <br />The powerline configuration in the vicinity of the batch -weigh system facilities was changed to accommodate the new <br />structures. Electrical equipment from the substation located at the site of the Batch -Weigh Coal Stockpile was <br />relocated to the substation installation adjacent to County Road 27. The 4,160 volt powerline, in the vicinity if the <br />batch -weigh system facilities, was rerouted as depicted on Figure 21. The existing 69 KVA powerline in the area was <br />• removed, with the poles reutilized in the new 4,160 volt alignment. A net of 9 poles were removed as a result of the <br />powerline reconfiguration. <br />A concrete pad is required for a transformer at the Batch -Weigh Loadout facility. The pad is a 6 x 8 x 0.5 feet and <br />is constructed of steel - reinforced concrete. Map 24 shows the location of this pad at the east end of the access road <br />to the Batch Weigh Loadout building. The transformer and pad will be removed when no longer needed. <br />Soray System <br />A pad was constructed between the batch -weigh system and the east end of the train tunnel to aid in application of <br />freeze -proof agents to the coal and car sides. The pad location is shown on Map 24, Surface Facilities. A metal <br />post with spray wand is anchored to the pad. The wand extends over the coal cars to apply side release agent to the <br />car. When the system is no longer needed, the pad, post, and spray wand will be removed from the site. This will <br />occur during final reclamation of the site, and final grading will be incorporated into railroad track removal. <br />Truck Loadout <br />In 2006, a new truck loadout was permitted to efficiently handle loading of an increased number of over - the -road <br />haul trucks transporting coal to the nearby Xcel Hayden Station Powerplant and other regional customers. The new <br />truck loadout is located in an existing coal stockpile area on the south side of Foidel Creek and the west edge of the <br />mine facilities area, west of the existing Batch -Weigh Railroad Loadout. Existing Haulroad A will be extended to <br />connect with Routt County Road RCR27 to provide direct truck access from the western portion of the mine <br />property under a separate Technical Revision submittal. Components of the truck loadout addition include: <br />• • Concrete reclaim bunker and vibratory feeder <br />• 10 -foot diameter steel reclaim tunnel <br />• 42 -inch diameter escape tube and fan <br />TR06 -53 2.05 -37.2 06/20/06 <br />
