buildiny, and on-grade conveyor sites would be graded and the trench exca- vated. Excess subsoil excavated from the trench not required in grading would be stockpiled alony the sides of the trench, The light-use road would be constructed for access to the conveyor route. The road connecting Steven's Gulch Road and the truck dump area would be constructed using con- ventional cut-and-fill techniques. The Type 5 CMP-culvert construction would require temporary detouriny of Farmer's Mine Road and State Hiyhway 133. Approximately one month's inter- ference to traffic at each road would be anticipated. Construction noise has been previously studied in RLM Environmental Assess- ment Record - Coal Lease Sale C-25079 and associated right-of-way C-25150. See Drawing 2A for results, Construction would typically be limited to day- light hours, The foundations for all structures would utilize conventional concrete forminy, reinforcing, and pouring techniques. The truck dump buildiny would be totally enclosed to enhance visual blending, reduce fugi- tive dust transport, and reduce operational noise, The structural steel supports would be erected utilizing conventional techniques. The conveyor belt would be enclosed by fences except at the Farmer's Mine Road and Fire Mountain Canal, If an archaeological site could not be avoided in Construction of a con- veyor, further documentation on the site would be completed before construc- tion proceeded. The short conveyor route and associated road would be located totally on CWI property. As a safety precaution, public access would be restricted on the light-use road and warning signs posted along security fences. ' The truck dump road construction would entail placement of subgrade material after proper elevation grades had been excavated, The road would be asphalt paved to reduce fugitive dust during operations, The stacking conveyor and downcomer tube would be constructed for stockpiliny coal in this area, The conveyor, support structures, stockpiling equipment, and truck dump buildiny would be painted to blend in with natural background colors. Mechanical and electrical construction would be a small portico of the over- all construction, Bins, chutes, motors, controls, and baghouses would be completed to maximize the efficiency and minimize impacts of the conveyor, The downhill short conveyor would be equipped with a regenerative braking device that would generate excess electrical power, The short conveyor would be constructed on a Colorado t4ined Land Reclamation Division designated alluvial valley floor (AVF) on areas south of Fire Moun- tain Canal, The existiny storaye and loadout area is on the same AVF, Reclamation procedures for the AVF are described in the reclamation section followiny, All disturbed areas would be graded and revegetated during the Spring or Fall following completion of construction, see Appendix "E" for seed mix- tures, Operation CWI would haul to the Steven's Gulch truck dump and short conveyor in inter- vals throughout a 24-hour period. Start-up of the truck dump and short con- veyor would result in a Mine Safety and Health Administration (MSHA) reyuired alarm. 23
