MANAGEMENT <br />June 20, 2008 <br />Mike Boulay <br />Division of Reclamation, Mining and Safety <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br />Re: CAM-Colorado LLC <br />Red Cliff Mine <br />Permit Application C-2008-086 <br />RECEIVED <br />JUN 2 3 2008 <br />Division of Reciamation. <br />Mining and Safety <br />Dear Mr. Boulay: <br />The DRMS' letter dated June 5, 2008 deemed the referenced permit application <br />incomplete. On behalf of CAM-Colorado LLC, following are its responses to the DRMS' <br />comments and concerns. <br />1. No response required. <br />2. DRMS - The discussion of mine water discharge remains an issue. Based on the <br />information provided in CAM Colorado's response and the permit application <br />package, there does appear that there will be mine inflow during the life-of-mine <br />operation. CAM has stated in the response and on page 2.04-39 that there <br />should not be any mine inflow during the first permit term. However, the narrative <br />on page 2.04-22 provides an estimated future inflow rate after several years of <br />mining up to 250 gpm. Maps 10 and 14 indicate that saturated conditions will be <br />encountered during year six (which is within the life of mine) and there is still an <br />incomplete discussion of the handling, plan for treatment and potential for <br />discharge from the mine during the life of the operation. Rule 2.0.5.6(3)(b)(ii) <br />requires a plan for treatment for groundwater drainage from the area and <br />proposed quantitative limits on pollutants in discharges subject to applicable <br />State and Federal laws. There is no discussion in the Probable Hydrologic <br />Consequences (2.05.6(3)(b)(iii)] regarding the impacts of mine discharge during <br />the life of operation. Therefore, CAM-Colorado has not minimally addressed the <br />requirements of 2.05.6(3). <br />CAM - Page 2.04-22 and 2.04-39 were amended to utilize the predicted <br />pumping rate from the mine based on URS' modeling. The plan for treatment of
