INSPECTION REPORT <br />Site: National King Coal Mine, Hesperus, Colorado <br />Inspected By: Don R. May, P.E., Project Engineer <br />Inspection Date: Quarterly Inspection January, 2007, (4"' Qtr <br />Ponds: Photograph 1 shows the snow covered west pond. The inlets, outlets and <br />embankments of both ponds were inspected and appear in good condition but snow <br />cover preludes detailed examination. <br />4rainaoe Ditches: The drainage channels, on the north and south sides of the waste <br />pile, appear in good general condition. All other drainage d~annels on the site were <br />inspected and are in good condition. Again snow cover makes dose inspection difficult. <br />The drainage in and around the upper and lower yams is working well and both are in <br />good shape. Care should be taken to keep all of the pipe inlets clear of sediment and <br />debris. Except where noted, all drainage features have been constructed and are <br />operating as stated in the drainage plan submitted to the Division of Minerals and <br />Geology. <br />Coal Waste Pile: The upper portion of the waste pile (above the road) appears stable <br />and in good condition. The lower portion of the pile face is also stable but does have <br />some tilling which is probably due to the over steeping at the toe. The design <br />modification for the toe of the waste pile that was suggested in the previous inspection <br />reports has been constructed. Photograph 2 shows the concrete block wall at the toe of <br />the slope. This should help slow the erosion on the lower portion of the waste pile face. <br />A second course of concrete blocks would raise the wall to the elevation of the <br />surrounding toe and eliminate the near vertical drop seen just above the existing wall. <br />The top of the pile is in good condition and is shown in photograph 3. Drainage on top of <br />the pile and along access road up the face and around the pile is working well with no <br />signs of undo erosion. <br />Eiccept for the items mentioned above the fill on the waste pile has been constructed as <br />spedfied in the design approved by the Division of Minerals and Geology. <br />
