Box 187 <br />Executive Director <br />Craig, Colorado 81626 <br />Loretta Pineda <br />Director <br />RE: Trapper Mine, C- 1981 -010; <br />2011 Annual Hydrology Report; Adequacy Review No. 1 <br />Dear Mr. Roberts, <br />The Division received the required annual hydrology report for the Trapper Mine on March 15, 2012. There were <br />several issues that will need to be addressed before the Division can complete its review of the report. <br />Groundwater Monitoring Frequency: <br />1.) Water monitoring for well P -3 ceased 2005 and 2003. The monitoring schedule noted on Table 4.8 -13a indicates <br />List C and D parameters are to be sampled at this well during the 2nd and 3rd quarter respectively. Please explain <br />this discrepancy. <br />2.) Water elevation monitoring occurred twice in 2011 for well P -5. Based on the operational ground water <br />monitoring schedule noted on Table 4.8 -13a, this well is to receive quarterly water elevation measures. Also, it <br />appears the third quarter water quality sampling for the List B parameters was not reported in the 2011 AHR for this <br />well. Please address this issue. <br />3.) Water elevations were not reported for the 1st quarter in 2011 for the Coy well. Please explain why this data was <br />omitted. <br />This concludes the Divisions initial review of the report. Please respond to the items listed above by August 10, <br />2012. If you have any questions, please feel free to contact me at (303) 866 -3567 ext. 8120. <br />Sincerely, <br />Jared Ebert <br />Environmental Protection Specialist <br />DRMS <br />Office of Office of <br />Mined Land Reclamation Denver • Grand Junction • Durango Active and Inactive Mines <br />
