-: <br />~~ <br />INSPECTION REPORT <br />Site: National King Coal Mine, Hesperus, Colorado <br />Inspected By: Don R. May, P.E., Project Engineer <br />Inspection Date: March 26, 1993 <br />March 30, 1993 <br />Coal Waste Pile: The coal waste pile and the surrounding azea were inspected for compliance <br />with the state approved design and for signs of instability and erosion. The waste pile <br />remains in basically the same condition as it was during the last inspection with no visible <br />problem areas. <br />No new work has been performed on the pile or the drainage system since the December <br />inspection. Jim Delusio, yazd foreman, said that work will begin soon. Photographs ~1 and <br />~Y2. show the drainage ditch on the north hillside of the eastside valley which will be used to <br />divert uncontaminated upstream flow around the waste pile. The ditch was roughed in last <br />fall and will be cleaned and riprapped this spring. As seen in the photos the banks, in places, <br />have sloughed and debris has fallen into the ditch. Portions of the ditch, photo k3, are more <br />stable. <br />As reported in the December inspection, a small amount of mine waste was stockpiled <br />adjacent to the road approximately at the location where the bottom the fill will be as shown <br />in the reclamation design, see photo ~i3. This material will need to be removed prior to <br />construction of the tce drain and waste pile intercept ditch. <br />Sediment Ponds: The waste ponds were inspected for sedimentation and erosion. As seen in <br />photo #5 the west pond has standing water in it from snow melt. The ponds are in good - <br />wndition. The elevation of the low level outlet on the west pond may need to be adjusted <br />based upon the results of the survey performed by Harry Ranney in October. <br />
