Box 187 <br />Craig, CO 81626 <br />RE: Trapper Mining, Inc., Permit C-1981-010 <br />Fourth Quarter 2010 Sediment Pond Inspections <br />Dear Mr. Puls: <br />COLORADO <br />D IV IS I ON OF <br />RECLAMATION <br />MINING <br />SAFETY <br />John W. Hickenlooper <br />Governor <br />Mike King <br />Executive Director <br />Loretta E. Pineda <br />Director <br />The Colorado Division of Reclamation, Mining, and Safety (Division) has reviewed and found the above referenced <br />report to be in compliance with the following regulations: <br />4.05.9(14)(b) - The impoundment has been maintained as designed, in accordance with the approved <br />plan and the applicable regulations. <br />4.05.9(15) - Certified inspection reports shall include: Any appearance of erosion, instability, <br />structural weakness or other hazardous conditions. <br />4.05.9(17) - All impoundments shall be examined at least quarterly by a qualified person designated <br />by the operator, for appearance of structural weakness and other hazardous conditions. <br />4.05.9(17) - A copy of the report shall be submitted to the Division on a quarterly basis. <br />The fourth quarter sediment pond inspection reports were received by the Division on January 31, 2011. Sediment pond <br />inspections were conducted by TMI between November 4 and December 31, 2010. <br />From the inspection reports, the identified maintenance items include: <br />• replacement of identification signs for No Name #2, Middle Flume #3, East Middle Flume, and Horse #1; <br />• replacement of sediment marker for No Name #5, Horse #1; <br />repair of the riser for No Name #4; <br />filling of burrows on the Johnson #6 embankment. <br />There are discrepancies regarding the level of sediment in Grouse #1 Pond and Horse Gulch Pond. The inspection <br />reports indicate that these ponds contain minimal sediment; however the summary table indicates that they do contain <br />sediment (50% in Grouse #1 and 25% in Horse). Also, the Industrial Waste Pond is not included in the summary table, <br />nor are the maintenance items in the inspection report listed in the cover letter of the submittal. Please clarify these <br />discrepancies. <br />Note that some maintenance items have been identified during prior inspections and should be addressed as soon as <br />practical. If you have any questions feel free to contact me at (303) 866-3567, extension 8113. <br />Sincerely, <br />Robert Zuber, P.E. <br />Environmental Protection Specialist <br />Office of Office of <br />Mined Land Reclamation Denver • Grand Junction • Durango Active and Inactive Mines
