Box 187 <br />Craig, CO 81626 <br />RE: Trapper Mining, Inc., Permit C-1981-010 <br />First Quarter 2010 Sediment Pond Inspections <br />Dear Mr. Mattern, <br />COLORADO <br />D IV IS I ON OF <br />RECLAMATION <br />MINING <br />SAFETY <br />Bill Ritter, Jr. <br />Governor <br />James B. Martin <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 first quarter sediment pond inspection reports were received by the Division on April 5, 2010. Sediment pond <br />inspections were conducted by TMI on March 11, March 29, and March 30, 2010. <br />From the inspection reports, the identified maintenance items include: sediment removal in West Pyeatt #01 and filling of <br />burrows on the face of Industrial Waste Pond #01. The latter item may not be necessary but this embankment should be <br />monitored. <br />Per the report, all ponds were functioning as designed at the time of the inspections. <br />Per Rule 4.05.9(15)(d), these pond inspection reports should include the existing storage capacity of each impoundment. <br />Please add this item to future submittals, either in a summary table or on each report. It would be helpful to also include <br />in this discussion the design storage of each pond, although this last item is not specifically required by this Rule. <br />If you have any questions feel free to contact me at (303) 866-3567, extension 8113. <br />Sincerely, <br />0` ZZ--- <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
