The railroad spur alignment begins with an eastbound connection to the Union Pacific trackage and <br />• heads in the southerly direction, crossing Highway 40. The railroad spur alignment continues in <br />a southerly direction paralleling the easterly side of County Road 37, and crosses the county <br />road just prior to the beginning of the loop track. The train enters the loop tack and moves on <br />to the Union Pacific connection for market delivery of [he coal. <br />The profile grade for the spur was designed to follow as much as possible the natural terrain, <br />and to minimize excavation and embankment requirements and maintain the required train operation <br />conditions. Figure 12-2 (Exhibit M. Volume I, Permit C-80-003 application package) shows the <br />railroad spur profile and typical cross-section. <br />The excavation and embanlcnent slopes are 2h:ly or flatter. Prior to excavation and embanl[nent, <br />the topsoil was removed and stockpiled for later use in the reclamation of the railroad. The <br />topsoil stockpile was seeded to prevent erosion. <br />The railroad spur crosses walker Ditch (a privately-owned irrigation ditch) and the loop track <br />crosses Dry Creek at two locations. Each of these crossings are made by using culverts. This is <br />consistent with other downstream crossing of both walker Ditch and Dry Creek. The maximum length <br />of the unit train is 73 cars. The railroad spur is designed to provide adequate length such that <br />the county road will not be blocked during loading operations. <br />• Support Facilities. (IDtietirv3) <br />The following facilities are shown on Exhibit 12-1, Facilities Map and IDchibit 12-2, Surface <br />water Cbatrol Plan Map. <br />Truck Dumping Facility. Haulage trucks durt~ run-of-mine coal into a 75-tom capacity conical <br />steel hopper. A welded grizzly with 12 inch openings is located above the hopper to prevent <br />large pieces of coal from entering the coal handling system. An emergency coal storage area is <br />provided adjacent to the truck dump area. <br />Crushing Station. A single-roll crusher is supported in a metal building, above-ground <br />structure. The crusher is a flexible-toothed, hammermill type crusher, driven by an electric <br />motor with fluid coupling drive. <br />Storage. A conical storage pile containing sized coal provides a surge capacity of unit <br />train loading operations. Coal is conveyed from the crushing station to the storage pile by a 36- <br />inch wide belt conveyor. The belt conveyor drive is located at the discharge end of [he belt and <br />belt tensioning is accomplished by a counterweight system. Coal is discharged from this belt <br />• conveyor into a concrete lowering tube. Coal is lowered inside the tube and discharged into the <br />pile through a series of staggered openings in the tube wall. Coal is reclaimed Erom storage by <br />four vibratory feeders located beneath the storage pile in a concrete tunnel. A 60-inch wide <br />reclaim belt conveyor receives the coal from the feeders and discharges [o a second 60-inch wide <br />belt conveyor for elevating the coal to the top of the unit train loadout facility. <br />6 Reu'sei 05/00 <br />
