Ponds 1 (large pond, outfall 001) and 2 (small pond, outfall 002). The two sediment control ponds <br /> were approved for removal in Technical Revision 15 (approved in January 2008)and MR-6 (vegetation <br /> cover data, approved August 11, 2008). Both ponds were in good shape, with no problems found with <br /> discharge structures, embankments and inslopes. <br /> Carbon Junction channel. The reconstructed section of the channel was in good shape with large rock <br /> riprap in place and the two 5 %2 -foot diameter culverts extending underneath the haul road. Vegetation <br /> debris and sediment has been washed into the channel,but the culverts contained little sediment,indicating <br /> no recent significant flow through the culverts. <br /> Sediment control. Rainfall in Durango the two days preceding this inspection totaled 0.04 inches as <br /> reported in the Durango Herald. The vegetative cover established on the disturbed areas of the Carbon <br /> Junction Mine appears to be effectively controlling erosion. No significant gullies or sediment fans were <br /> found on the site. Erosion on the disturbed areas of the site appears to be occurring at a rate similar to <br /> adjoining undisturbed lands. <br /> Backfilline and Grading <br /> Backfilling, grading, topsoil replacement, and seeding appeared to have been completed in all areas <br /> within the permit area except topsoil stockpiles 4 (north of pond 1), 7 (southeast of pond 2), and 8 <br /> (south of pond 1); the two sediment control ponds (1 and 2); various ditches; and various boreholes. <br /> The base of the North Pit reclaimed slope is contoured to act as a grass filter for trapping sediment in <br /> runoff coming off of the slope where the south half of the North Pit was approved as a small area <br /> exemption in TR-14. <br /> Support Facilities <br /> No problems were found in the Equipment Storage Area at the south end of the permit area. Equipment <br /> previously stored there has been removed from the site. Release of Phase I reclamation liability for <br /> removal of the equipment could be applied for in a bond release application. <br /> Topsoil <br /> The stockpiles on either side of the pond are well-vegetated, are not gullied, and do not have weed <br /> problems. <br /> Revegetation <br /> The areas that were backfilled, graded, topsoiled, seeded, and mulched in summer 2006 developed a <br /> nurse crop of sterile wheat/oat hybrid, a product called Regreen. This nurse crop has since given way to <br /> 4 <br />
