7' <br />5. Water level monitoring was not provided for well TC-1. On page 155, it is stated that this <br />well is under pressure so water elevation in the Rollins Sandstone cannot be determined. Please <br />provide further clarification for the lack of water level monitoring. <br />6. On page 136-137, data are presented for Outfall 011. Beginning with the July, 1998 data, <br />it appears that Total Fe and TDS data have been transposed. Please clarify this and submit revised <br />pages. <br />7. On page 151, it is stated that S-2 is only sampled when S-l has flow (spring runoff and <br />significant precipitation events). This would indicate that other times of the year, the flow a[ S-2 <br />would be comprised primarily of mine discharge. Because S-2 is located immediately upstream of <br />the Noah Fork, monthly field parameters are useful in identifying any potential impact to the North <br />Fork of the Gunnison River. The Division requests that Oxbow Mining, Inc. continue to sample S-2 <br />according to the approved monitoring plan. This includes monthly field parameters and a quarterly <br />full suite analyses. <br />8. From the discussion on page 153, it is unclear whether or not Spring #7 produces enough <br />water during the spring months to obtain a sample for field measurements. Please provide further <br />clazification for the lack of monitoring data for 1998. <br />Please let me know if you have any questions regarding my review. <br />
