At the completion of mining, Trapper's surface water will be utilized in the former mine permit area <br />for watering livestock and wildlife. Based on Trapper's 2007 AHR, the current surface water quality is <br />suitable for those uses. The suitability of Trapper's surface water for wildlife and livestock is expected <br />to continue based on long-term trends in Trapper's water data. <br />The only apparent major hydrologic impacts at Trapper are TDS loading. Values of total suspended <br />solids (TDS) were on the low side of ranges observed in previous years. The TDS of the surface water <br />from the mine area is similar to the TDS from the non-mined area; therefore, an increase has not been <br />defined, except for an increase in TDS during low-flow conditions. <br />Discharges at the Trapper Mine are regulated by the Colorado Discharge Permit System permit number <br />CO-003115. No discharges exceeded permit criteria during water year 2007. <br />Please feel free to contact me with any questions at (303) 866-6424. <br />Sincerely, <br />Jason Musick <br />Environmental Protection Specialist <br />Cc: Dan Hernandez, CDRMS
