_, <br /> <br />March 19, 1982 <br />Mr. Robert Liddle <br />Mined Land Reclamation Division <br />Colorado Department of Natural Resources <br />1313 Sherman Street, Room 423 <br />Denver, Colorado 80203 <br />Dear Mr. Liddle: <br />III IIIIIIIIIIIIIIII <br /> <br />r~~rz 2 2 1982 <br />rJ~IrdED LAND R~CLAr~ATlt7N <br />Colo. Dept. of ~datlral Rescuree~ <br />Attached is information submitted to me by John Nelson, Keenesburg <br />Mine Manager, concerning Stipulation 18 to our Permit. The information <br />addresses the geometry (height and slope angle) of the overburden spoil <br />stockpiles and the method of placement of material. <br />Shown on Appendix t4-2 and M-5 is the approximate area extent and <br />typical cross-section geometry of the initial overburden spoil pile and <br />the regraded temporary spoil pile. The most northerly extent of the <br />regraded, combined Piles 1 and 2 will be as indicated by the dashed line <br />labeled "EDGE OF SPOIL" on Appendix M-2. The southerly extent will be <br />approximately as indicated in the area south of Pile 1., but south of <br />Pile 2 the edge will be about 200 feet further southwest than shown. <br />The detailed geometry of the piles (initial and regraded) in the <br />Pile 2 area is shown on the attached cross-sectional drawings. As this <br />spoil pile is developed to the southwest, the configuration will more <br />closely approximate the typical cross-sections shown in Appendix M-5. <br />John rielson has also furnished the attached narrative information <br />on spoil pile design and material emplacement procedures. <br />Please call me at 277-1629 (277-6005 after rlarch 26) if there is <br />further information either John or I can provide to resolve this issue. <br />WSR:bd <br />Sincerely yours, <br />William S.
