III IIIIIIIIIIIII III <br />TRAPPER ~INI1~G I1~C. <br />RECEIVED <br />oGT 2 z. SAT <br />October 2l, 1997 <br />GWyl~n pf Mlnilftpe A Qotl~~' <br />Mr. Tom Kaldenbach <br />Environmental Protection Specialist <br />Colorado Division of Minerals and Geology <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br />Dear Tom: <br />Re: Trapper Mine Third Quarter 1997 Sediment Pond Inspections <br />Impoundment inspection results for the third quarter of 1997 aze enclosed. The inspections were <br />performed by qualified inspectors under my supervision. <br />At the time of the inspections the ponds were functioning as designed and required maintenance items <br />wen: not significant. Sediment was removed from East Pyeatt No. 1 and Elk ponds during the quarter. <br />The flume below Coyote dam was also re-leveled and stabilized. <br />As you know, heavy rains occurred during lace September. These "events" exceeded the design <br />capacity of our stmctures. Outflow erosion and flume displacement occurred in some areas. At least <br />three ponds received a significant amount of silt and require cleaning (East Pyeatt No. 1 has already <br />been cleaned; Oak No. 1 is currently being cleaned). At your request an inventory of damage and a <br />schedule of repairs is being developed by our EQ Departrnent. The fourth quarter inspection report will <br />address the damages and repairs in more detail. <br />Call if you need any additional information. <br />Sincerely, <br />:~ ,~~. <br />James M. Mattem <br />CO PE 20537 <br />c FV lyke <br />P.0. Box 187 Craig, Colorado 81626 (303) 824-4401 <br />
