June 4, 2012 C- 1981- 016/Hawk Nest E & W JRS <br />RECLAMATION SUCCESS (cont.): There were no erosional problems noted on this portion of the mine. <br />Surface water flow is directed into a roadside ditch and flows either east or west. The flow to the east goes into a <br />culvert, under old Highway 133 and into a small rock and grass lined ditch at the lower mine area. This flow <br />travels over the lower mine area and eventually ends up in the North Fork of the Gunnison River. There was no <br />sediment in the ditch, culvert or outlet of the culvert and no off -site impacts were seen. The flow to the west goes <br />into a culvert, under old Highway 133 and into a large rock and grass lined ditch at the lower mine area. The <br />water then flows off -site and, ultimately, into the North Fork of the Gunnison River. There was no sediment in the <br />upper ditch, the culvert, the culvert outlet, the ditch or the outlet of the ditch. There were no off -site impacts seen <br />as a result of the upper east mine area or the ditches. <br />- The bleeder entries area is a small (approximately 1/2 acre), steep area above old Highway 133. The area was <br />stable, with no erosional problems noted. Surface water runoff from the bleeder entry area of the mine flows into <br />a roadside ditch and into a culvert that runs under old Highway 133. There was no sediment in the roadside ditch <br />or the culvert. There was no evidence of any off -site impacts from the bleeder entries. <br />- The west mine area is divided into two parts, one above old Highway 133 and one below old Highway 133. Both <br />areas were stable and well vegetated. No erosional problems were noted at the west mine area. Surface water <br />runoff from the west upper area flows into a roadside ditch and, ultimately, into a culvert which goes under old <br />Highway 133 and into the North Fork of the Gunnison. There was no sediment in the roadside ditch or the culvert. <br />Runoff from the east portion of the upper area flows into a large, riprapped ditch in the natural drainage. The <br />water then goes into a culvert and, ultimately, into the North Fork of the Gunnison River. There was no sediment <br />in the ditch or at the outlet of the ditch. Surface water from the lower portion of the west mine flows into two <br />small ditches on either side of the site (the east or west side) and then out of the disturbed area and, ultimately, into <br />the North Fork of the Gunnison. There was no sediment in either of these ditches and no sediment was seen <br />leaving the site. There is a small sediment pond that remains in place at the lower area and it was dry at the time <br />of the inspection. There were no offsite impacts seen at either the upper or lower areas of the west mine. <br />- Overall, the reclamation at the Hawk's Nest Mine is doing well. The entire site remains stable and there <br />are no erosional problems at the site. There were no signs of any off -site impacts at the east mine, bleeder <br />entries or west mine as a result of the reclamation. The Division is satisfied with the reclamation success <br />and is conducting year 9 and 10 vegetation sampling in an effort to terminate its jurisdiction on the site. <br />Year 9 sampling was scheduled for and conducted on 6 June 2012 and year 10 sampling will be conducted <br />in June or July 2013. <br />DOCUMENTS RECEIVED: None <br />This concludes the 4 June 2012 OSM Oversight inspection report for the Hawk's Nest Mine. <br />Number of Partial Inspection this Fiscal Year: 4 <br />Number of Complete Inspections this Fiscal Year: 2 <br />Page 3 of 4 <br />
