• Regrading of the lower parking area and the preparation plant will begin with clean-up of refuse and coal stockpiles. This material will be placed in the RSRDA or CRDA-1. Concrete, asphalt and other non-toxic material remaining after demolition of the surface facilities will be dozed into the area to be backfilled along the east edge of this site. Additional soils will be graded over this fill to establish the final contours shown on Exhibit 6C. Again, topsoil was not salvaged for this area, so some of the best available soil in this area will be used as the final cover. Excess material taken from this area will be used to complete the cover for the RSRDA and fill elsewhere on the site. Reclamation of this area will include Haul Road 1. The 9.5' diameter conveyor culvert under this area leading under the highway and over to the river will be left in place. The conveyor culvert will be demolished and backfilled where it emerges from the ground west of the I-70 frontage road. A minimum of 100-feet of culvert will be filled with soil. The 4-inch diameter mine dewatering pipe which runs through the conveyor culvert to outfall 001 will be abandoned. Access Road 1 will be backfilled and graded when no longer needed for access to the portal bench or the RSRDA. The original road cut was below sections of nearly vertical rock faces. Fill on this road will begin near the center of the road and extend to a height of approximately 15' leaving some • vertical rock faces. Care will be taken when filling this area to use the best soils for final cover. The drainage plan for the South Portal is shown on Exhibits 6C and 26. Run- off calculations are presented in Appendix 14-6, pages 14-6-1 through 14-6- 18ix. The drainage ditches will be constructed except where they cross pond 8 and pond 9. Pond 8 will receive interim run-off from ditch segments E, F and G. Pond 9 will receive interim run-off from the RSRDA upper diversion ditch, segments A, B and C, and a portion of the lower bench of the RSRDA. The ditches will temporarily discharge into the two ponds to provide sedimentation control until their removal is approved by the DMG. Once pond removal is approved, the ditches will be constructed "through" the reclaimed ponds so the final drainage configuration is complete. Ditch section H-H' will be constructed after pond removal is approved. Miscellaneous grading for the site will be at the A substation, Light Use Road 1, and the Water tank shown on Exhibit 6A, Tab Section 13. Grading of these sites will involve minor cuts and fills to blend in with adjacent surface contours. B-Substation was removed and the area graded during 2002. • 14-8 (Rev. 12/02)
