SHELTO N, Director <br />MEMORANDUM <br />~~ 1 March 1985 <br />T0: <br />FROM <br />RE: <br />Robert Liddle ~~(~_ <br />Jim Pendleton ~- <br />ARCO Lands ide Rem ial Proposal - Electric Substation Slide <br />Pursuant to your request, I have reviewed West Elk Coal Company's proposed <br />landslide remedy for the slide located immediately above the upper electrical <br />substation at the Mt. Gunnison No. 1 underground coal mine. The plan proposes <br />the installation of a soldier pile and concrete lagged retaining wall upslope <br />from the substation. Following installation of the cable anchored structure, <br />the majority of the surficial landslide debris will be excavated to reduce the <br />hazardous exposure of the substation. <br />This plan is acceptable as proposed with the following reservation. The <br />applicant must determine whether this change in the mine's operational <br />configuration necessitates an amendment to the originally approved reclamation <br />plan. If an amendment is necessary, then the plan should be appropriately <br />amended, as soon as possible. If an amendment is submitted, your <br />consideration would include appropriate surety adjustment. In either case, I <br />recommend that we convey an approval for the proposed landslide remedy <br />promptly, in order to expedite the repairs. <br />jP/JP <br />423 Centennial Building, 1313 Sherman Street Denver, Colorado 80203 Tel.
