Box 187 <br />Craig, Colorado 81626 <br />RE: Trapper Mining Inc., DMRS Permit No. C- 1981 -010 <br />Review of Fourth 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 the above referenced report. The <br />Discharge Monitoring Reports were received by the Division on May 7, 2012. The report covers the time period from <br />January 1, 2012 through March 31, 2012. <br />Eleven NPDES outfalls discharged during the first quarter of 2012. According to the report, the primary effluent <br />limitations were exceeded at six outfalls this quarter (001, 011, 017, 018, 020 and 021). TSS limitations were exceeded in <br />all six of these outfalls. Iron was exceeded in outfalls 017, 018 and 020. The explanation reported for these exceedances <br />is snowmelt and or precipitations events resulting from snowfall and rain. Rule 4.05.13(2)(a)(ii) requires the Division to <br />be notified within 5 days after analytical results of the sample collections indicate if noncompliance with a permit <br />condition or applicable stand has occurred. Overall, this report is in compliance with Rule 4.05.13(2) with this one <br />exception noted above. In the future, please notify the Division within the required timeframe of any exceedances of the <br />effluent limitations. <br />The report indicates outfalls 011, 020 and 021 were sampled for WET analyses during the quarter. No exceedances of <br />WET test limitations were reported at the tested outfalls. <br />If you have any questions, please feel free to contact me at (303) 866 -3567 ext. 8120. <br />Sincerely, <br />I � rak— <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 />
