No. 32. Modifications include removal of the four rock check dam swctures spaced at regular intervals along the segment, installation of concrete tvingvvall swctmes at Ute upper channel crossing, and placement of riprap armoring along the channel bank between Sediment Pond 6 and Ute upper channel crossing. Photo Set 5 The three photos show refuse azea CRDA-2 from various distances and perspectives. The lower three benches and a small portion of the fourth bench were covered with soil and revegetated in 1994. Remaining reclamation will include final grading, cover sailing and revegetation of Ute upper benches, and installation of a larger, higher gradient upper diversion along Ute upper perimeter of Ure refuse pile. The diversion currently in place is the serpentine feature visible in each photo on Ute steep canyon slope above the top of the pile. Due to its low gradient, Ure existing ditch requires fiequent maintenance to remove sediment accumulations and maintain adequate capacity for storm flow. In addition to its ]ow gradient, Ure ditch is topographically above the top of Ute refuse pile along its entire length. Should flood debris wash down Ute steep erosional chutes on Ute canyon slope, it is likely tl>at Ute ditch would be breached, resulting in significant erosion on Ute reclaimed refuse pile slopes. For Utese reasons, Ute existing ditch was ~ c determined to be inappropriate as a component of Ute final reclamation landscape, and will be replaced by the larger, higher gradient ditch, excavated to be lower that[ the top of pile elevation along its entire length. Total disturbance area associated with CRDA-2, including diversions and sediment pond, is approximately 32.7 acres. Photo Set 6 Two photos show the Unit Tmin Loading Facility, from different perspectives. Facilities include Ute rail spur loop, and extending into the rail loop from Ute southwest, the terminal portion of Ure overland conveyor system with associated transfer building and linear stacker (dismantled). The (tat area with visible coal residue is the clean coal storage pad, with reclaim tunnel, feeder conveyor, and train loading Q~ lower. Other facilities include sewage lagoon evaporative ponds, a sediment pond, and a water tank. Total acreage within the rail loop is approximately 46.2 acres. Reclamation will include removal of all facilities, grading to approximate original contour, and revegetation. Photo Set 7 Photo 7a shows PCC's reclaimed North Decline Area. The site is a reclaimed portal facility area located southeast of I-70, northeast of the South Portal Area. The reclaimed site encompasses most of the relatively flat, roughly triangular shaped area between the bluffs and the interstate, and includes a riprap lined drainage channel that runs through the center of the area. PCC monitors water levels in the mine workings via Well N-l, located in the norUteast comer of the reclaimed area. Disturbed acreage is approximately 18.4 oats. The belt of freshly exposed soil Ural extends aaoss the area on the left side of the photo is due to the recent installation of a water supply pipeline by Ute Water Company. Photo 7b shows the South Fan site, which was regraded and seeded this fall, along with Utc reclaimed access road to the site, and an associated reclaimed soil borrow area. The reclaimed areas are a lighter shade than surrounding rangeland, due to application of straw mulch. Total disturbance acreage is approximately 1 acre. The fan location is a remote site located southeast of the South Mine Facilities Area. An additional reclaimed portal site of similar acreage (Ute 2-West Portals), and three small electrical substation sites which have not been reclaimed, were conswcted at various locations over the South Mine workings. i
