2.05.4 Reclamation Plan No further coal mining will occur under this permit at the Carbon Junction Mine. At this time the surface disturbances associated with the Carbon Junction Mine; the North Pit, North Pit Haul Road, South Pit Drill Pad, Permanently Reclaimed Spoils Area, and Equipment Area have all been permanently reclaimed. The Carbon Junction Canyon Channel permanent diversion has been constructed. The access road to and through the mine site was approved for retention post-mine. Sediment Ponds #1 and #2 remain in place pending the approval of Technical Revision 15. Topsoil Stockpiles #4, #7, and #8 remain in place. Topsoil Stockpile #4 was to be used for reclamation of the Ewing #1 aggregate operation, but was not so used. The topsoil in this pile therefore is excess to the reclamation of the Carbon Junction Mine, and is proposed to be left in situ as a distinct landform. Topsoil Stockpiles #7 and #8 are slated for reclamation of Sediment Pond #1 and Sediment Pond #2. The reclamation plan is retained to describe the final reclamation activities that took place in 2006. 2.05.4(2) Reclamation Plan Elements The total disturbed area remaining at the Carbon Junction Mine to be reclaimed under this permit was slightly over 37 acres at the beginning of 2006. The approved post-mining land uses for the mine are industrial and commercial, recreation, and residential. Oakridge Energy, Inc., is planning a large development on the entire mesa, of which the Carbon Junction Mine constitutes only a small portion. Goff Engineering of Durango has been retained by the landowner to design the development and work with the appropriate agencies on securing all permits required. A Cross-Section Map provides a comparison between the existing and final topography. The Final Contour Map shows the reclaimed contours at a contour interval of two feet. Completed Reclamation North Pit Reclamation Coal stripping occurred at this location during the operation of the Carbon Junction Mine. Pre- reclamation disturbance consisted of the exposed sandstone layer forming the base of the coal seam that was mined, a relatively flat bench area, and adjacent downspoiled fill below the bench. Reclamation of the North Pit involved the following tasks undertaken between May and August 2006: 1) Returned downspoiled fill from the slope below to the North Pit bench area. Downspoiled material was used to partially backfill the bench area and sandstone scarp. A large tracked excavator was employed for this task, sited on an intermediate bench below the main bench.
