SHELTON, Director <br />April 14, 1987 <br />Mr. Larry Reschke <br />Project Engineer <br />Snowmass Coal Company <br />P.O. Box 1354 <br />Palisade, Colorado 81526 <br />Re: Annual Hydrologic Report, 1986 - Permit No. C-81-025 <br />Dear Mr. Reschke: <br />The Division has reviewed the Annual Hydrologic Report. The North Thompson <br />Creek Mines are presently in the process of being totally reclaimed. A change <br />in personnel lead to several sites not being sampled in accordance with the <br />approved monitoring plan. However, due to the lack of activity at the mine, <br />no data of significance was lost. The monitoring of wells, associated with <br />the refuse pile undergoing reclamation was conducted in accordance with the <br />plan. Also, the wells required to be more frequently monitored upon flooding <br />of the mines had appropriate monitoring accomplished. <br />Mo significant variations in water quality were noted. The No. 3 Mine is <br />being flooded so this discharge to North Thompson Creek is no longer <br />occurring. The No. 1 Mine discharge is still occurring. <br />Snowmass needs to request a technical revision to remove or replace Well No. 1. <br />If you have any questions, please call me. <br />Sincerely, i <br />Candace M. Thompson <br />Hydrologist <br />ChfT/vj r <br />8895E <br />423 Centennial Building, 1313 Sherman Street Denver, Colorado 80203-2273 Tel. (303) 866-3567 <br />
