Please respond to the questions as appropriate within 60 days of receipt of this letter. <br />General Comments and Errors/Omissions <br />Some items are identical to concerns outlined in the Foidel Creek AHR for <br />monitoring sites which are shared. They are as follows: <br />a) Figure 13 plot shows exactly the same values for site 1002 and <br />006-AW-2, which is apparently incorrect. <br />bl 63.4 feet to water in well 006-AW-2? <br />c) Values on or around August 22, 1992 show an apparent doubling of <br />two separate value throughout the report. <br />d) Site 307 elevation does not match between the data sheet and <br />Table 1. <br />e) Site 8 elevation values also do not agree between all sources. <br />2. The text says all Mine 2 ponds are in the Fish Creek drainage, yet Pond K drains <br />to Foidel Creek. Please correct this information. <br />3. Please refer to the October 29, 1992 CYCC response to the Division's review of <br />the 1991 AHR. Questions a) and b) under General Comments were not <br />corrected as stated in your response. <br /> <br />STATE OF COLORADO <br />4.

Please explain in detail. <br />
