SHELTON, Dlreetor <br />July 20, 1987 <br />Mr. Dennis Conn <br />West Elk Coal Co <br />Box 591 <br />Somerset, CO 81434 <br />RE: Mt Gunnison No 1 Proposed Decision (C-80-007) Technical Revision No. 54 <br />(Reduction-Hydrology Monitoring) <br />Dear Mr. Conn: <br />The Colorado Mined Land Reclamation Division proposes to approve your <br />technical revision application (reduction-hydrology monitoring) for the Mt <br />funnison No. 1 Mine (our File C-80-007). Notice of the proposed decision will <br />be published as soon as possible. The publication will initiate the ten (10) <br />day public comment period for the Division's decision. <br />One issue which we discussed as a part of this revision review process was the <br />resumption of monitoring at Horse Creek, South Prong and Beaver Reservoir <br />prior to mining beneath these areas. Currently WECC does not plan to permit <br />mining in these areas for several years and/or a few permit terms. At that <br />time the Division would suggest that WECC plan to monitor three times <br />corresponding to the start of spring runoff, peak runoff, and low flow for <br />flow, pH, E.C., temperature, total manganese, total iron, 7DS and TSS prior to <br />mining. <br />If you have any questions, please contact me. <br />Sincerely, <br />Susan Mowry <br />Reclamation Specialist <br />4051G <br />423 Centennial Building, 1313 Sherman Street Denver, Colorado 80203-2273 Tel.
