COLORADO <br />Division of Reclamation, <br />Mining and Safety <br />Department of Natural Resources <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br />April 13, 2014 <br />William A. Bear <br />Bowie Resources, LLC <br />P.O. Box 483 <br />Paonia, CO 81428 <br />RE: Bowie No. 2 Mine (Permit No. C- 1996 -083) <br />2013 Annual Hydrology Report Review <br />Dear Mr. Bear, <br />The Division has completed its review of the above referenced report received on 13 May 2014 <br />via email. The Division finds the 2013 Annual Hydrology Report in compliance of the <br />requirments identified in the attached memo. The report fulfills the 2013 requirement to file <br />an annual hydrology report. The Division has the following comments: <br />1. Data is presented in tabular form for all monitoring points, and in graphic form for <br />several of the monitoring points. In future reports it would be beneficial to organize <br />the data graphically for all monitoring points. <br />2. It would be beneficial if BRL would plot the upstream and downstream data for each <br />surface water site on one graph, to better illustrate the downstream trends. <br />3. Inclusion of baseline data for all of the ponds enables the Division to easily compare <br />current conditions with baseline. Some of the ponds include baseline data, but several <br />do not (Figures 174 -181 do not). Please include baseline data for all ponds in future <br />reports <br />4. It would be beneficial, in the graphical information for the monitoring sites, to include <br />a point along the sample date axis indicating the changeover from baseline to <br />operational data. <br />Please give further attention to the following items: <br />1. Figure No. 81, B- Gulch -lo, includes lab data for a June 17, 2013 monitoring event, but <br />the corresponding field data indicates "No Flow." Please provide clarification on the <br />discrepancy. <br />2. Figure 88, C- Gulch -lo, includes a flow value of 5 gpm on June 17, 2013. No lab results <br />were presented for that sample date. Please provide lab data for C- Gulch -lo on June <br />17, 2013 or clarify as to why an analysis was not conducted. <br />O .OF' 2 0� <br />e� O <br />1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http: / /mining.state.co.us * *i <br />John W.
