Thompson Colorado Mined Land Reclamation Division 1313 Sherman Street Denver, Colorado 80203 August 6, 1985 -•.inTlo RES LLD:Nq ---:;r,.,op soza~ RE: Response to the Division's Technical Revision Adequacy Review for the Hydrologic Monitoring Program; Wyoming Fuel Company -New Elk, Golden Eagle Mines Dear Ms. Thompson: We have received and reviewed your June 14, 1985 letter regarding review of our proposed hydrologic monitoring program for 1985. Generally, we agree with the findings of your review, however, there are a few points which need clarification. 1. /The frequency of monitoring and parameter list for the two backfill channel alluvial ,v/ wells at the New Elk Mine does not correspond with the requirements for Stipulation No. 8 of Technical Revision No. 1 to the permit. We assume that your June 14 letter contains the parameters to be analyzed and the frequency to be monitored. 2. Wyoming Fuel proposed to monitor alluvial wells in apache (ACAW-1) and Ciruela _ (CCAW-1) Canyons which do not appear on your list. We assume therefore, that there is no requirement to monitor these stations. 3. Wyoming Fuel would like some additional in-sight as to the purpose of maintaining the long list of quality parameters at the four alluvial well stations (PAW-1, PAW-2, PAW-3 and PAW-4). Following a full year of baseline data collection, many of these parameters were consistantly at or below detection limits which was our logic for proposing the parameters on the short list. If the short list is adequate for the two ~' newly installed wells (PAW-3 and PAW-4 in the backfilled channel) why must the long list be maintained where we have data indicating no problems? 4. Wyoming Fuel would like additional in-sight as to the purpose of a one time monitoring of the 8 springs and seeps within the one mile perimeter of the permit boundary. As indicated in our presentation of last year's data, August was the high flow month because a series of heavy thunderstorms produced additional alluvial flow. The spring and seeps are the result of sandstone and shale outcrops which bring the alluvial flow to the surface. The conclusion from last year's data was that none of the 8 springs and seeps were a significant contributor to surface flow because they generally responded to precipitation conditions of the area. If we want to gage relative moisture during the growing season, Wyoming Fuel currently operates a precipitation station at each mine which are reported in the annual summary of data.
