minimal impact on streamflow quantity, as flow in Calamity Draw is dominated by irrigation return <br />flow. Decreased sediment loads predicated by SEDCAD+ indicate that reclamation efforts <br />wnducted in the mining area will ensure that additional contributions of suspended sediment in <br />runoff from reclaimed areas will not occur. Effects of runoff from reclaimed areas on the quality <br />of streamflow. Based on past operating history at the Nucla Mine, no significant trend toward <br />higher concentrations of the selected parameters have been detected. In addition, the pond <br />discharge will be monitored in accordance with NPDES discharge limitations and any potential <br />impact will be identified. Therefore, runoff from the reclaimed area should have no significant <br />impact over time on the quality of receiving stream water quality. As a result, post mining land uses <br />which currently occur in the area should not be affected due to the mine plan which has been <br />approved. <br />Summary. The discussion presented herein of the probable hydrologic consequences of the <br />revised mine plan approved by W FC identifies the potential effects of mining. Table 2.05.6(3)-1 <br />summarizes the discussion by listing the probable hydrologic consequences and the results of the <br />analysis of each. As can be seen, all of the probable impacts have been determined to be of a <br />short term nature, of minimal significance, or a plan has been presented to mitigate those <br />determined to have some significance. As a result, mining and post mining affects to current land <br />uses should be negligible. <br />(REVISED 25 Jul 2002) 2.04.7-50 <br />
