Page 6 of 6 <br />within and adjacent to <br />reclamation at the Seneca II Mine <br />the permit area <br />is the minimum that can be <br />expected from a reclaimed surface <br />mine at this location. Use of best <br />management practices indicates <br />minimization of disturbance to the <br />hydrologic balance. <br />23. Prevention of <br />CDRMS regulation <br />YES <br />Surface water — Predictions were <br />material damage to the <br />4.05.1(1) <br />made for the TDS increases to be <br />hydrologic balance <br />observed on Fish Creek during the <br />outside the permit area <br />months of June and July due to <br />discharges from the Seneca II <br />Mine. In June, an 18% increase <br />was predicted between SSF11 and <br />SSF13. In July, a 13% increase was <br />predicted between SSF11 and <br />SSF13. Based on the information <br />provided there was a 9% increase <br />in TDS in June and a 2% increase in <br />July. It appears that the run -off <br />from Seneca II has little impact on <br />Fish Creek. <br />Ground water — No material <br />damage has occurred, as discussed <br />in item 20, above. <br />24. Agreement of <br />CDRMS regulation <br />YES <br />observed hydrologic <br />2.05.6(3) and <br />No local or regional impacts were <br />impacts with "probable <br />requirement to keep <br />observed.

A <br />determination should be made <br />based on the NPDES Compliance <br />Schedule to meet the selenium <br />limit by December 31, 2015 <br />associated with the NPDES permit. <br />25.
