<br />-8- <br />previous subarea begins. Reclamation of each subarea involves covering the <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 control erosion. A series of three loose rock <br />check dams have been installed along Scullion Gulch below the D-Portal Area to <br />provide adequate sediment control while the D-Portal area is being reclaimed. <br />
