All highwall slopes were reduced to slopes between 2.Sh:ly and Sh:ly. This produced a final topography that could not only be revegetated, but would also allow drainage to flow through the pit area without impounding water. Stability of the regraded spoil did not present any significant problems due to the compaction of the material by grading equipment and the predetermined slopes. There were no variances from AOC requirements or highwall reclamation requested or allowed in the permit azea. The Postmine Contour Map, Exhibit 12-9 was compazed with USGS 7.5 minute Quadrangle Map of Mount Hams and Milner, Colorado to determine if post-mine drainages were constructed in appropriate locations with adequate drainage density. Pre-mining topography was also compazed with the approved Postmine Contour Map to verify that regraded slopes achieved AOC. All regraded slopes were inspected and evaluated for erosional stability during the Phase I bond release inspection and routinely during normal monthly inspections. Results of these evaluations aze discussed below in Section III Observations and Findings. The final reclamation plan for the Seneca R Mine includes retention of numerous permanent facilities including roads and culverts, pos[mine drainage channels, sedimentation ponds, and stock ponds. The structures approved as permanent facilities were evaluated as part of this Phase I bond release and are summarized below. There are approximately 13.5 miles of haul roads that were retained as permanent roads. These sections of haul roads were converted to access roads. Permanent roads are discussed in the PAP on page 13-52. All other operational road sections other than those listed below have been fully reclaimed, SCC has retained the following designated roads as permanent: Pre-Law Road, Road C, Road E, Road El, Road F, and South Road. These roads aze shown in the PAP on Exhibit 13-2A, post-mine permanent road cross-sections aze presented in Exhibit 13-2B, and permanent road profiles aze shown on Exhibit 13-2C of the PAP. The following actions were completed to convert the operational haul roads to post-mine access roads: 1) The top road surface was narrowed to approximately twenty feet, 2) The road surfacing material from any narrowing of a section was placed on the remaining road width; and 3) All areas te-disturbed by road narrowing activities were re- seeded to the edge of the road surface. The following existing culverts were evaluated and approved as permanent structures and will remain as post-mine features: 2A, 2AA, 3A, 9A, 12A, 13A, 15A, 18A, 19A, 24A, 29A, 30A, 32A, 33A, 45A, 47A, 62A, A3, and A5. Culvert locations aze given on Exhibit 13-2A in the PAP. The Seneca II Mine is located within two adjacent drainage basins: Grassy Creek and Fish Creek. $oth of these aze sub-basins of the upper Yampa River basin in northwestern Colorado. Surface water runoff and sediment control consisted of the construction and maintenance of sedimentation ponds, stock ponds, and postmine drainage channels. Sedimentation Ponds 002, 003, 004, 008, and the PECOCO Pond shown in the PAP on Exhibit 7-19, Postmining Drainage Control and Exhibit 13-2A, Postmining Topography and Permanent Features will remain as permanent structures. SCC has submitted permanent impoundment demonstrations to DRMS for all ponds except the Tmck Wash Ponds and Spill Control Pond which will be reclaimed 7
