<br />DEPARTMENTOF NATURAL RESOURCES <br />David H. Getches, F~cecutiva Director <br />MINED LAND RECLAMATION DIVISION <br />DAVID C. SHELTON, Director <br />Richard D. Lamm <br />Governor <br />August 29, 1984 <br />Mr. Rocky Bowman <br />West Elk Coal Company <br />P.O. Box 591 <br />Somerset, Colorado 81434 <br />Dear Mr. Bowman: <br />The Division has received and reviewed the plan to repair the landslide which <br />occurred in April, 1984. This plan was submitted to our office as requested <br />by Mr. Gary Takenaka, Mine Engineer. The Division approves this mitigation <br />plan. <br />The Division does have some concern about future maintenance problems <br />resulting from freezing. The pipes which discharge into the collection basin <br />may freeie thereby limiting the discharge of the interflow ground water <br />collected in the drain. Ice blockage may also occur. You stated that it will <br />be easier to monitor, maintain and correct any future problems of this surface <br />system. I agree that monitoring and correction will be easier, however, <br />maintenance may be a problem. <br />If maintenance is performed I believe the system should function adequately. <br />In the event the system becomes impractical to maintain or does not function <br />adequately, the entire drain system in this slide area may need to be <br />re-evaluted. <br />If you have any further questions or comments please contact me or Bob <br />Liddle. Enclosed is a copy of this letter for Mr. Takenaka. <br />Sincerely, <br />~~~i.,-"""- <br />Philip C.
