Box 70 <br />Loma, Colorado 81524-0070 <br />RE: 1994 Annual Hydrologic Report (C-80-004 and C-81-020) <br />Dear Mr. Walters: <br />II~~~ <br />DEPARTMENT OF <br />NATURAL <br />RESOURCES <br />Ru/ Romer <br />Govcrno~ <br />Wmee 5. lrx hheaA <br />E.ec W ive Direnor <br />Mrchael B. Long <br />Div isiun Dueam <br />The Division has reviewed the referenced 1994 Annual Hydrologic <br />Report and found it to be in compliance with permit requirements as <br />outlined in the applicable findings documents. Data and <br />interpretations included in the report appear to be consistent with <br />PHC projections. <br />The suggestion in the text of the report to discontinue monitoring <br />well GW-4 and substitute monitoring of GW-3 would appear to be <br />reasonable. The proposal should be submitted as a technical <br />revision to the McClane and Munger applications. <br />Finally, as I had previously discussed with you, there appear to be <br />some discrepancies between the currently approved monitoring plans <br />as described in the pertinent findings documents for both mines, <br />and the monitoring plans as described in the permit volumes on file <br />in Grand Junction. I would suggest that, in concert with the <br />proposed technical revision and the upcoming midterm for Munger <br />Canyon, we endeavor to ensure that the monitoring plans set forth <br />in the application documents correspond to the monitoring plans <br />specified in the findings documents. <br />Please contact me if you have any questions. <br />Sincer~ ~/cL~ <br />Dan T.
