Hydrology reports indicate that a <br /> water level at all wells fell within <br /> their historic ranges, with the <br /> exception of SGAL70, COV2633, <br /> COV2702, CW2632, and CW2701. <br /> Overburden wells COV2633 and <br /> COV2702 and wadge coal wells <br /> CW2632 and CW2701displayed <br /> the lowest water level on record. <br /> However, monitoring of these <br /> wells began in 2008; so long term <br /> data is not available. All alluvial <br /> wells showed seasonal water level <br /> fluctuations in response to periods <br /> of precipitation or lack thereof. <br /> Spoil well water levels indicate <br /> that down slope highwall portions <br /> of the spoil exhibit significant <br /> amounts of saturation. <br />21. Prevention of CDRMS regulation YES Underground mining at the PSCM <br />impacts to ground 4.05.11(2) has yet to commence and no <br />water that adversely mining was undertaken during the <br />impact post-mining land 2010 water year. <br />use <br />22. Minimize CDRMS regulation YES The disturbance to the hydrologic <br />disturbance to 4.05.1(1) balance within and adjacent to the <br />hydrologic balance permit area caused by mining and <br />within and adjacent to reclamation at the PSCM is the <br />the permit area minimum that can be expected <br /> from a reclaimed surface mine at <br /> this location. Use of best <br /> management practices indicates <br /> minimization of disturbance to the <br /> hydrologic balance. Mining had <br /> yet to begin during the period of <br /> record for the 2010 AHR. <br />23. Prevention of CDRMS regulation YES Surface water - No surface water <br />material damage to the 4.05.1(1) impacts due to mining have not <br />hydrologic balance occurred, as mining and <br />outside the permit area construction related activities due <br /> to mining have yet to commence. <br /> Ground water - No material <br /> damage has occurred, as discussed <br /> in item 20, above. <br />24. Agreement of CDRMS regulation YES Impacts due to mining have not <br />observed hydrologic 2.05.6(3) and occurred as mining and
