<br />..~ <br /> <br />~I I I I~ I I~ I I~ III II~ <br />sss <br />July 16, 1987 <br />GOLD HILL VENTURES <br />P.O. Box 1523 <br />Longmont, Colorado 80502 <br />449-7746 (Millsite) <br />651-2985 (Office) <br />Mr, Edward L. Bischoff <br />Minerals Supervisor <br />Mined Land Reclamation Division <br />423 Centennial Building <br />1313 Sherman Street <br />Denver, Colorado 80203 <br />RE: CASH MINE, File M-83-141 <br />Dear Mr. Bischoff: <br /> <br />RECEIVED <br />,~UL 171987 <br />MINED ~-AND <br />RECLAMATION DIVISION <br />This letter is being submitted to the Mined Land Reclamation <br />Division in accordance with the Amendment Conditions attached to the <br />Cash Mine Limited Impact Permit approved on September 26, 1985, by <br />the Mined Land Reclamation Board. <br />1. The initial tailings impoundment storage area occupies a rectan- <br />gular shaped area that has the dimensions of 275 feet by 100 feet at its <br />longest and widest points. The toe of the tailings dam extends for 330 <br />feet along its outer face from the northeastern edge to the southwestern <br />edge of the structure. A revised Millsite and Tailings Pond Reclamation <br />Plan Map that reflects these changes will be submitted to the Mined <br />Land Reclamation Division. <br />Following the completion of the tailings dam construction earth <br />work, the following sequence of geomembrane liner installation was <br />followed: <br />1. All sharp rocks, large stones, roots, vegetation, and other <br />foreign material were removed from the interior of the tailings <br />impoundment area. <br />2. All of the remaining surface irregularities were smoothed <br />out and a layer of compacted decomposed granite was placed on <br />the bottom and sides of the tailings retention structure. <br />3. An anchor trench 24 inches wide by 36 inches deep was dug <br />with a baekhoe around the inner perimeter of the tailings dam to <br />hold the edge of the geomembrane liner. This trench was dug a <br />minimum of at least 1 foot from the interior slope of the tailings <br />impounding area. <br />
