debris and sediment has been washed into the channel, but the culverts contained little sediment, indicating <br />significant flow may have not yet occurred in the culverts. <br />Backfilline and Gradine <br />Backfilling, grading, topsoil replacement, and seeding appeared to have been completed in all areas <br />within the permit azea except topsoil stockpiles 4, 7, and 8; the two sediment control ponds (1 and 2); <br />various ditches; the two sediment basins that are to be constructed at the base of North Pit in Carbon <br />Junction Canyon (see page 5-6 of the reclamation plan); and various boreholes. The base of the North <br />Pit reclaimed slope is contoured to act as a grass filter for trapping sediment in runoff coming off of the <br />slope. <br />Drainage control. Although no water was flowing on the site, positive drainage appeared to exist <br />throughout the drainage route from backfilled azeas to the ponds. Pond 1 receives runoff from the north <br />half of the North Pit reclaimed slope, the east half of the PRSA, the South Pit Drill Pad, and the Equipment <br />Yazd. Runoff from the west half of the PRSA reports to Pond 2. Runoff from the south half of the North <br />Pit passes through a grass filter terrace at the base of the reclaimed slope and then flows to the newly <br />constructed Carbon Junction channel via the ditch next to the North Pit Haul Road. The south half of the <br />North Pit reclaimed slope was recently approved as a small azea exemption in TR-14. <br />Suaaort Facilities <br />No problems were found in the Equipment Storage Area at the south end of the permit area where several <br />large pieces of equipment remain. The equipment includes: 2 hydraulic shovels, 1 drill rig, 1 dump track, <br />4 service trucks, 1 coal dryer, I crop disker, 1 automobile, 4 haul trucks, and 12 truck tires. Reclamation <br />liability for the following items cannot be released until the equipment is removed: a) equipment removal <br />and b) backfilling and regrading where the equipment is located. <br />General Mine Plan Compliance <br />The operator is progressing toward completing the reclamation plan. <br />Reveaetation <br />The August 2006 inspection report found that on the azeas reclaimed in summer 2006, drill seeding <br />appeazed to have been conducted on flat-lying azeas and broadcast seeding appeared to have been <br />completed on steeper slopes. All seeded azeas had been covered with a few inches of straw mulch. A <br />nurse crop of sterile wheat oat hybrid, a product called Regreen, is providing good vegetative cover on <br />the backfilled and regraded areas. <br />Slides and Damaee <br />Backfill on the northern edge of North Pit remains severely eroded where runoff from the adjacent <br />sandstone outcrop reaches the backfill. This erosion has been noted in previous reports. Drainage is <br />not yet adequately re-established at this location, as the reclaimed slope needs protection from runoff <br />coming off of the sandstone. <br />Gully development appeazs to have increased on the backfilled slope along the northeastern base of <br />North Pit, just upslope from Cazbon Junction Canyon. The reclaimed slope at this location is steep and <br />4 <br />
