Mountain Coal Company <br />West Elk Mine <br />Post Office Box 591 <br />Somerset, Colorado 81434 <br />Telephone 970 929-5015 <br />Fax 970929-5595 <br />July 12, 1996 <br />Mr. Michael Boulay <br />Colorado Division of Minerals and Geology <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br />ocrFl\/ED <br />JUL 17 ~ggg <br />iii iiiiuiiiiiiiiiil <br />999 <br />Division of Mmerais & Geology <br />RE: French Drain Construction; f~/est Elk 1S'[ine; Permit No. C-SO-007 <br />Dear Mr. Boulay: <br />During May of this year, Mountain Coal Company (MCC) constructed a french drain in the <br />cutslope of the material storage bench. The construction of the french drain was approved by the <br />Division in Minor Revision No. 185. The purpose of the french drain was to collect springs that <br />were emanating from two thin coal seams. The french drain has been successful in collecting the <br />water. <br />Following the construction of the french drain it was observed that there are two more coal seams <br />that are located below the bottom elevation of the french drain. MCC plans to construct an <br />additional french drain to collect the water that is emanating from these coal seams. The french <br />drain will be constructed as the french drain in Minor Revision No. 185 was constructed. A <br />trench, approximately 10 feet deep will be lined with a 30 ml PVC liner and gravel placed in the <br />trench. The french drain will daylight on the west end of the cutslope and connect to the eight <br />inch surface ADS pipe, which was installed during the construction of the first french drain. MCC <br />is planning to begin this work this week. <br />cc: Norm Every <br />Idrr~sb.doc <br />Please tail if you have any questions. <br />
