<br />INSPECTION REPORT <br />Site: National King Coal Mine, Hesperus, Colorado is ~' ~ , 5 <br />Inspected By: Don R. May, P.E., Project Engineer ~~'o :.y~ G~d~_o~% <br />Inspection Date: Quarterly Inspection April, 2006 <br />~L Ems.--. <br />,.,ar-- , <br />Ponds: Photograph 1 shows the west pond with some standing water. The inlets, <br />outlets and embankments of both ponds were inspected and appear in good condition.. <br />Both ponds are relatively clean of sediment and appear to have more than adequate <br />storage volume. As mentioned in the last report the staff gage marked with the pond <br />bottom elevation is missing from the west pond and a replacement would help the <br />operator determine when and how much sediment removal is needed:- - <br />Drainage Ditches: The drainage channels, on the north and south sides of the waste <br />pile, appear in good general condition. Alf other drainage channels on the site were <br />inspected and are in good condition except for the possible elevation problem described <br />in the last report for the ditch near the old tipple and the east pond. <br />A portion of the upper yard is seen in photo 2. Inlets, ditches and overland flow through <br />and around the upper and lower yards is work well. Both the upper and lower yards are <br />in 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 face of the waste pile is shown in photo 3. It appears stable <br />and in good condition. The lower portion of the pile face is also stable but does have <br />some rilling which is probably due to the over steeping at the toe. <br />The top of the pile is in good condition. A portion of the top of the waste pile, near the <br />face, is shown in photo 4. Drainage along waste rock pile access road up the face and <br />around the pile is working well with no signs of undo erosion. <br />Except for the items mentioned above the fill on the waste pile has been constructed as <br />specified in the design approved by the Division of Minerals and Geology. <br />
