(c) A plan for backfilling soil stabilizing compacting and grading, with postmining contour maps and appropriate cross-sections that are typical and representative of the anticipated character of the final surface configuration of the proposed permit area in accordance with 4.14 for stream channel reconstruction in accordance • with 4.05.4 and for road removal or modification in accordance with 4.03.. RESPONSE Reclamation of all mining and related disturbance will generally involve the same sequence and type of activities: • Salvage and removal, or demolition of equipment and facilities • Removal and disposal of any non -suitable surfacing materials • Backfilling and regarding disturbed areas • Reestablishment of effective drainage • Soil material replacement and preparation • Revegetation The objectives of all reclamation activities are to return disturbed areas to a stable configuration which blends with the surrounding terrain, promotes effective drainage, meets all applicable regulatory requirements and permit commitments, and which is consistent with the approved postmining land uses of rangeland and wildlife habitat. The following sections discuss relevant reclamation details for specific disturbance areas. Parking Areas After the employee parking area (east of the mine office) and the mine ready -line parking area (west of the operations center) are no longer required, any parking islands will be removed and the associated scrap metal and concrete will be placed in the portal area and buried. Similarly, paving material will be ripped, loaded, placed in the portal area, and .buried. Since the paving material has been placed over the previously regraded and compacted surface, the previously designed and approved regrading plan for these areas will not be impacted, and reclamation of the areas will be completed with regrading, drainage reestablishment, topsoil replacement and reseeding. C, Portal Area The rough grading of the spoils at the portal area will be accomplished by pushing the old spoil into the pit. Dozers will be utilized to cover and rough grade the refuse area with spoil material. The material storage yard will be restored by pushing the fill portion of the yard back into the cut area as shown on Cross -Sections B -B and C -C on Map 25, Surface Area Cross -Sections. The access/haulroad will be regraded by pushing the fill portions into the cut areas. The spoil material will be compacted, graded and stabilized by the equipment used to place the spoil materials. Map 31, Postmining Topography, and Cross -Sections A -A, B -B, D -D, E -E, F -F, G -G, H -H and Y-1 on Map 25, Surface Area Cross -Sections, show the final surface configurations in detail. The upland diversions are shown on Map 25, Cross -Sections H -H and Y -Y. The designs for these channels are provided in Exhibit 8-R, Grading operations will be conducted to reestablish an approximate original contour configuration and to avoid the creation of long uninterrupted slopes. Since there are no steep slopes in the proposed permit area, cut and fill terraces will not be installed. Grading will result in an undulating topography, thereby increasing moisture infiltration, reducing runoff potential, and minimizing erosion. Topsoil will be distributed as shown on Map 29, Reclamation. Portal Slope Heating System Upon completion of mining, the slope heating system will be dismantled and the small associated building will be removed. The concrete pad will remain in place and will be buried during reclamation of the portal area. RN08-05 2.05-99 03/12/10
