1` <br />INSPECTION REPORT <br />Site: National King Coal Mine, Hesperus, Colorado <br />Inspected By: Don R. May, P.E., Project Engineer <br />Inspection Date: December 21, 1992 <br />December 28; 1992 <br />Coal Waste Pile: The coal waste pile and the surrounding area were inspected fo_r 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 has been in for the past year, with no visible <br />problem areas. <br />Portions of the technical plan as outlined in the Waste Bank Design report have been <br />constructed. This includes the drainage ditch on the north hillside of the eastside valley which <br />will be used to divert uncontaminated upstream flow around the waste pile. The new access <br />road, located to the south of the new ditch is partially complete, see photographs. <br />A small amount of recent mine waste has been stockpiled adjacent to the road <br />approximately at the location where the bottom the fill will be as shown in the rec]amation <br />design. This material will need to be removed prior to construction of the tce drain and <br />waste pile intercept ditch, see photographs. I will alert King Coal that until the drain and <br />ditch are constructed in the spring, waste should be dumped on the existing pile. <br />The attached sketch shows the design configuration and what needs to be constructed prior <br />to piling waste in a new location. Riprap should be place on portions of the new diversion <br />ditch as stated in the amendment to TR-4 dated February 25, 1992. <br />Sediment Ponds: The waste-ponds were inspected for sedimentation and erosion. Although <br />snow covered, the ponds appear in good condition. Recent construction brought the ponds <br />into compliance with state regulation. The elevation of the low level outlet on the west pond <br />may need to be adjusted based upon the result of the survey performed by Harry Ranney in <br />October. <br />RECD@0>/~- <br />DEC 311992 <br />DIVi,iIGP~ C)r` <br />MINERALS & UECL «~~- <br />
