STATE OF COLOR ~,v <br />Roy Romer, Governor <br />DEPARTMENT OF NATURAL RESOURCES <br />MINED LAND RECLAMATION DIVISION <br />FRED R. BANTA, Director <br />May 30, 1989 <br />Mr. William Agnew <br />Trapper Mining, Inc. <br />P.O. Box 187 <br />Craig, Colorado 81626 <br />RE: Technical Revision to 1988 Annual Report Appendix W at the Trapper Mine <br />File No. C-81-010 TR-44 <br />Dear h1r, Agnew: <br />The Division has recently completed an adequacy review for TR-44 and intends <br />to approve the revision as submitted with one exception. Trapper proposed to <br />remove the quarterly analysis of Total Dissolved Solids (TDS1 from ground <br />water monitoring requirements. The Division agrees that wells in the HI, KLM, <br />QR and Twentymile Sandstone aquifers have shown consistency with regards to <br />TDS levels and the quarterly requirement for TDS analysis could be dropped. <br />Therefore, upon approval of this revision the following wells will no longer <br />re~,uire quarter]y TDS analysis b~t will stiles require annual TDS ana~sis: <br />GA-) , GA-2, GB- -1 , GD~, GE-1 , GE-2 GF-1 , GFw2, GF`~3, GF-4, GF~6, <br />GP=I, GP!~, - GP -4 GP- GP-6, GP~1 and G~B. However, the White <br />Sandstones, Baccfi nd luvial aquifers have shown more variable levels of <br />dissolved solids with some significant increases in 1988. Therefore, <br />quarterly analysis of TDS should continue for wells monitoring these aquifiers. <br />As soon as the Division receives a letter of concurrence from Trapper a <br />decision will be issued. If you have any questions or wish to discuss <br />this revision further, please call. <br />Sincerely, <br />C-~~ ~ ~-- <br />Anthony J. Waldron <br />Reclamation Specialist <br />AJW/eke <br />6627E <br />-. <br />215 Centennial Building, 1313 Sherman Street Denver, Colorado 80203.2273 Tel. (303) 866-3567 <br />
