road culverts. Ditches and drainage control will be established during construction and maintenance of the <br />roads to minimize erosion and to assist traffic passage. • <br />Design and Construction. Light-use roads will be field engineered to follow the existing topography as much <br />as practicable. Topsoil will be removed and stockpiled in accordance with the topsoil salvage plan. <br />The horizontal and vertical alignment will be dictated by the topography and the need to avoid obstructions. <br />Light-use road surfacing material will be adequate for the use of the road. Acid or toxic-forming substances <br />will not be used in the road surfacing. Light-use roads will be maintained to minimize erosion and to allow <br />passage of traffic. <br />Reclamation. SCC will reclaim alight-use road when it is no longer needed in accordance with the <br />reclamation plan. The road will be closed to vehicular traffic. The natural drainage patterns will'be restored. <br />All culverts will be removed. Roadbeds will be ripped, plowed or scarified. Cut and fill slopes will be <br />rounded or reshaped and blended into the surrounding topography. Cross drains, dikes or water bars may <br />be constructed to contrcl erosion as required. Road surfaces from which topsoil has been removed will be <br />covered with topsoil and revegetated in accordance with the reclamation plan. <br />Several postmine landowners have indicated to SCC that they intend to re-establish are-mine ranch <br />roads. The approximate travel way of these ranch roads are shown on Exhibit 20-2. SCC will regrade <br />the area of the ranch road to approved postmine topography and revegetate it in accordance with the <br />Revegetation Plan. The postmine landowner(s) plan to establish atwo-track path across the <br />postmining landscape to improve access to their property(s) -the ranch roads will not be surface, <br />nor will there be any drainage control features installed. <br />Support Facilities <br />Buildings Proposed buildings consist of a bathhouse trailer (14'w x 38'I x 8'h), and a shop building (40'w x <br />100'Ix 20'h). These buildings were constructed on the mine site in 1990. Exhibit 13-1 shows the mine <br />support facility area. <br />Waste Water Waste water and sewage will be disposed of by septic systems. The office/shop building <br />complex will have a septic Sank and leach field located southwest of the buildings. <br />Domestic Water. A water well will be drilled in the yard area northeast of the office/shop building complex <br />as shown on Exhibit 13-1. Well specifics are detailed in Tab 7. <br />Solid Wastes. Solid waste will be collected in dumpsters or other suitable containers and disposed of at an <br />approved dump site off the mine property. There is no solid waste disposal area at the Seneca II-W <br />mine site. <br />J <br />PR-06 38 Revised 01/06 <br />
