-8- <br /> Reclamation of each subarea involves covering the <br /> previous subarea begins. Re 9 <br /> completed pile with four (4) feet of non-toxic, non-combustible fill material <br /> (subsoil ) followed by placement of 1 .5 feet of suitable topsoil material . The <br /> topsoiled area is then seeded and mulched in accordance with the approved <br /> revegetation plan. <br /> Mine-related surface disturbances to be reclaimed at the end of the mine's <br /> life consist of the D-Portal area, water storage area, overland conveyor <br /> route, slot storage facility, rail loadout/loop, ventilation facility, and the <br /> alluvial well field located at the mouth of Scullion Gulch near County Road <br /> 65. Reclamation of these areas involves sealing of all portals, removal of <br /> all surface structures, backfilling to approximate original contour, <br /> re-establishment of affected drainages, replacement of stockpiled topsoil over <br /> regraded areas, and seeding and mulching of all topsoiled areas during the <br /> fall planting season (October-November). Application of fertilizer over <br /> seeded areas will be based,on the results of site specific fertility testing <br /> of topsoiled areas. <br /> At the D-Portal area, reclamation will involve re-establishing the Scullion <br /> Gulch drainage channel to its' approximate original meander and gradient. <br /> This will entail removing the mine bench and large culvert diversion system <br /> placed underneath the mine bench during construction of the D-Portal facility. <br /> Access roads to each of the above facilities will also be reclaimed as <br /> • described above with the exception of County Road 65 and the portion of the <br /> refuse disposal haul road situated north of County Road 65. These two roads <br /> will be retained as part of the approved post mining land use of the area. <br /> The refuse haul road will be partially reclaimed, however by reducing the <br /> width by 1 /2, shortening all culverts accordingly and topsoiling and seeding <br /> the regraded portion of the road. <br /> With the exception of the D-Portal area sediment pond (Pond DP-1 ) , all <br /> sediment ponds controlling runoff from the various surface facilities areas <br /> will be retained until vegetation on reclaimed areas has become sufficiently <br /> established to effectively' controi erosion. A series of three loose rock <br /> check dams have been installed along Scullion Gulch below the 0-Portal Area to <br /> provide adequate- sediment control while the D-Portal area is being reclaimed. <br />
