installation would be completed by a specialty construction and engineering co,npany (maximum of 43). When possible, local contractors would be hired for earthwork, steel construction, and general construction work (maximum of 111), Approximately eighteen months would be required to complete construc- tion of the overland conveyor, See Figure #1 for construction schedule and manpower requirements. Conventional earthmoving equipment would be utilized to clear vegetation from the conveyor route including the trench, the at-grade conveyor por- tions, Lhe transfer point, and the light-use maintenance road routes, and this cleared vegetation would be hauled to the Delta County landfill for disposal. Drainage control measures would be utilized to reduce or elimi- nate erosion and sedimentation. Such measures as straw dikes, sedimentation ponds, etc., would be constructed as required. Existing irrigation ditches would be relocated during non-irrigation so no interruption of irrigation flow would occur. Topsoil would be stripped from all these sites and stored in stockpiles as described in the Orchard Valley Mine mining and reclamation permit. The light-use maintenance roads, support structure, transfer build- ing, and on-grade conveyor sites would be graded and the trench excavated. Excess subsoil excavated from the trench not required in grading would be stockpiled along the sides of the trench, The light-use roads would be con- structed for access to the conveyor route. The Type 5 CMP culvert construction would require temporary detouring of Farmer's Mine Road and State Highway 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 Rights-of-Way C-25150. • See Drawing 2A for results, Construction would typically be limited to day- light hours, The foundation for all structures would utilize conventional concrete form- ing, reinforcing, and pouring techniques. The transfer building would be totally enclosed to enhance visual blending, reduce fugitive dust transport, and reduce operational noise. The structural steel supports would be erected utilizing conventional techniques. The north belt has sufficient overhead Type 3 construction so as not to affect wildlife movement. The south 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, further documentation or archaeology on the site would be completed before construction proceeded, The conveyor route would cross Federal (BLM) and CWI property, see Drawing d13. Appropriate applications would be completed by CWI for Federal right- of-way before construction was started, As a safety precaution, public access would be restricted on the light-use conveyor maintenance roads. The conveyor would not restrict hunter access to these areas. The conveyor, support structures, and transfer building would be painted to blend in with natural background colors. Mechanical and electrical construction would be a small portion of the over- all construction. Sins, chutes, motors, controls, and baghouses would be completed to maximize the efficiency and minimize impacts of the conveyor, The downhill conveyor would be equipped with a regenerative braking device that would generate excess electrical power. 13
