Page 5 of 5 <br />Groundwater — In TAB 17 of the PAP, predictions were made <br />as to the expected TDS increases to be observed at various <br />monitoring wells. Predicted TDS values were exceeded at 5 <br />of the 7 sites. No material damage has occurred, as discussed <br />in item 20, above. <br />24. Agreement of observed <br />CDRMS regulation <br />hydrologic impacts with <br />2.05.6(3) and <br />No local or regional impacts were identified in the AHR. This <br />"probable hydrologic <br />requirement to keep <br />observation is consistent with the PHC. <br />consequences" projected in <br />current, CDRMS <br />mining <br />regulation 2.03.3(1) <br />It is noted that the accidences of the CDPHE selenium <br />standard may need to be included in a revised PHC section of <br />the permit. A determination should be made based on the <br />NPDES Compliance Schedule to meet the selenium limit by <br />December 31, 2015 associated with the NPDES permit. <br />25. Adequacy of ground <br />CDRMS regulation <br />The current ground water monitoring program continues to <br />water monitoring program <br />4.05.13(1) <br />adequately address the protection of the hydrologic balance. <br />26. Adequacy of surface <br />CDRMS regulation <br />The current surface water monitoring program continues to <br />water monitoring program <br />4.05.13(2) <br />adequately address the protection of the hydrologic balance. <br />
