Alternative #"L - Steven's Gulch Truck Oump and Short Conveyor Alternative #2 is a combination of modified Alternatives #1 and #4. The truckiny of coal from the Orchard Valley Mine would continue, but would be restricted to Steven' the lower part of the s Gulch Road. A conveyor would take the coal across area to the silo storaye facility. Physical Description Tanden (multiple unit) trucks haul coal from the Orchard Valley Mine site to a new truck dump station constructed off Steven's Gulch Road near CWI's power substation (see Drawiny #4). From the Steven's Gulch truck dump, a 36 inch or 42 inch conveyor belt, 3,400 ft. in length would carry the coal to the silos at the train loadout area, The construction of the conveyor would be identical to the south conveyor for Alternative #1. The conveyor would be hooded and would be located in a trench from the Steven's Gulch truck dump to the Farmer's Mine Rvad (Type 4 construction) and on grade from the Fire Mountain Canal to the train loadout area (Type 1 construction), The conveyor would pass beneath the Farmer's Mine Road, Fire Mountain Canal, and State Highway 133 (Type 5 construction), The truck dump site would consist of a paved access road loop and a totally enclosed, truck dump building with emissions control such as spray bars or a vacuum baghouse. A stacking con- veyor and downcomer tube would also be constructed for stockpiling coal in this area. See Drawing #4A for site plan of the truck dump area. The short conveyor would consist of: Type 1 Low Profile 1730 feet Type 2 Bent Construction in Type i length Type 3 Raised Steel 270 feet Type 4 Trench Construction 910 feet Type 5 CMP Construction 490 feet • A security fence would be erected as necessary to safeguard various facili- ties, see Drawiny Nlb for location of fence. A light-use road would be con- structed parallel to the lower portion of the short conveyor from the truck dump buildiny to the train loadout area. Construction Construction activities on the short conveyor would be contained within a I00 ft, maximum riyht-of-way corridor along the conveyor route. The truck dump site would be constructed as shown on Drawing #4A. The conveyor manu- facturiny and installation would be completed by a specialty construction and enyineeriny company (maximum of 43). When possible, local contractors would be hired for earthwork, steel construction, and general construction work (maximum of 99). Approximately twelve months would be required to com- plete construction of the Steven's Gulch truck dump and short conveyor, see Fiyure #3 for construction schedule and manpower requirements. Conventional earthmvving equipment would he utilized to clear vegetation from the conveyor route and truck dump area. This would include the trench, the at-yrade conveyor portions, the truck dump site, and the light-use road route, and this cleared veyetation would he hauled to the Delta County land- fill for disposal. Drainaye control measures would be utilized to reduce or eliminate erosion and sedimentation. Such measures as straw dikes, sediinen- Lotion ponds, etc., would be constructed as required. Existing irrigation ditches would be relocated during non-irrigation times so no interruption of irriyation flow would occur. 7opsoii would be s[ripped from all sites and stored in stockpiles as described in the Orchard Valley Mine Mininy and Reclamation Permit, The liyht-use road, support structures, truck dump 20
