Oehler <br />State of Colorado <br />Dept. of Natural Resources <br />Division of Minerals and Geology <br />1313 Sherman St. Room 215 <br />Denver, Co. 80203 <br />Dear Mr. Oehler: <br />This letter will comment on your report dated July 1, 1993 which <br />covers the period February 24, 1993 Through June ~2, 1993. The <br />comeents are made on behalf of the Costilla Counl;y Conservancy <br />District and the other party objectors in the Battle) Mountain Gold <br />Mine case. The comments and questions will follow the format of <br />your report. <br />1. Increased Tailings Area Security <br />At the risk of sounding repetitious, we will again i form you as we <br />did on January 11, 1993, March 5, 1993 and March 1~, 1993 (Roger <br />Flynn's letter) we are not in agreement with any (change in the <br />permitted level of cyanide. <br />Your report refers to "process water cyanide stands ds set by the <br />Division (see February 24, 1994)". Your Februar 24th report <br />states that security will resume if pH exceeds 9.0 and/or WAD CN <br />exceeds 10 ppm. Are these the standards the Division) is now using? <br />3. Accelerated Frequency of Environmental Monitoring. <br />We have yet to see any results from Ann Maetz's independent <br />monitoring. What has happened to them? <br />Also, Maclovio reports that there is a substantial delay in the <br />reports coming to his office for public review. Th last reports <br />at his office were delivered on June 9, 1993 and these reports <br />detailed samplings from April 16, 1993. <br />4. Tailings Cyanide Detoxification. <br />What is being done to de-toxify the tailings placed during the <br />period of non-compliance? What is the level of cy nide in these <br />tailings? What is the level of cyanide in the eff~uent from the <br />tailings under drain system? <br />GREENWOOD EXECUTIVE PARK •6458 SOUTH QUEBEC ST BLDG S •ENGLEWOOD, CO 80111 •303-290-8361 FAX 303-290-6228 <br />
