Box 187 <br />Craig, Colorado 81626 <br />RE: Trapper Mining Inc., DMRS Permit No. C- 1981 -010 <br />Review of Third Quarter 2011 Discharge Monitoring Reports <br />For CDPHE Permit No. CO- 0032115 <br />Dear Mr. Roberts, <br />The Colorado Division of Reclamation, Mining and Safety (Division) has reviewed and found the above referenced report <br />to be in compliance with Rule 4.05.13(2). The Discharge Monitoring Reports were received by the Division on October <br />'11,2011. The report covers the time period from July 1, 2011 through September 30, 2011. <br />Six NPDES outfalls discharged during the third quarter of 2011. Outfalls 001 (Johnson), 002 (No Name), 011 (East <br />Pyeatt), 020 (Middle Flume), and 022 (Deal) discharged throughout the quarter. <br />The report indicates that no exceedances of the primary effluent limitations occurred during the third quarter. However, <br />due to an error at the lab, Total Iron data was not calculated for the samples taken on July 5, 2011. Total Iron values were <br />not represented on the DMR's for NPDES points 002, 011, 020, 022 and 024. According to your report, each outfall <br />exhibited extremely low TSS values for the month of July, and traditionally low TSS result in low Total Iron values. <br />Given this, it is likely no exceedances of Total Iron occurred at any outfall for July. <br />The report indicates outfalls 011 and 020 were sampled for WET analyses during the quarter. No exceedances of WET <br />test limitations were reported at the tested outfalls. <br />If you have any questions, please feel free to contact me at (303) 866- ext. 8120. <br />Sincerely, <br />?�" c4' <br />Jared Ebert, DRMS <br />Environmental Protection Specialist, DRMS <br />Office of Office of <br />Mined Land Reclamation Denver • Grand Junction • Durango Active and Inactive Mines <br />
