Box 359 <br /> Keenesburg, Colorado 80643 <br /> Re: Review of Keenesburg Mine Annual Hydrology Report <br /> Permit No. C-028-81 <br /> Dear Mr. Nelson: <br /> ,The Division has completed its review of Coors' Annual Hydrology Report and <br /> May 25, 1983 Addendum which responds to our review concerns. <br /> In general, we found the data to be well-presented, which made comparisons and <br /> trend identification easy. Your discussion of the interpretation of the data <br /> was extremely beneficial and, overall, the Division agreed with your <br /> conclusions. <br /> Only one concern was noted that needs to be responded to by Coors to resolve <br /> this year's annual report requirements: <br /> Coors committed to providing an annual report of pit inflows from the previous <br /> year, the amount of augmentation water released the previous year, and the <br /> proposed make-up water to be released for the coming year (see attached <br /> letters from Jack Hibbert of Adolph Coors Company and Hal Simpson of the <br /> Colorado Water Resources Division) . This information has not been provided to <br /> MLRD; it was specifically requested in our last review letter. It may be that <br /> the information was forwarded to the Water Resources Division without copying <br /> MLRD. In any case, this information needs to be promptly provided to both <br /> Divisions. A deadline of June 22, 1983 is hereby imposed for the submittal of <br /> the complete report, since this report is a part of a permit stipulation <br /> agreed to by Coors. If the deadline is not met, or the report is incomplete, <br /> the Division will consider appropriate enforcement action. <br /> 423 Centennial Building. 1313 Sherman Street Denver, Colorado 80203 Tel.
