• 101 Effects of runoff from reclaimed areas on the quality of streamflow. Due to the relatively small <br />area of disturbance in the New Horizon 2 mining area, any reductions in runoff will have only a minimal <br />impact on streamflow quantity, as flow in Calamity Draw is dominated by ircigation return flow. <br />Decreased sediment loads predicated by SEDCAD+ indicate that reclamation efforts conducted in the <br />mining area will ensure that additional contributions of suspended sediment in runoff from reclaimed <br />areas will not occur. Effects of runofffrom reclaimed areas on the quality of streamflow. Based on past <br />operating history at the Nucla Mine, no signifcant trend toward higher concentrations of the selected <br />parameters have been detected. In addition, the pond discharge will be monitored in accordance with <br />NPDES discharge limitations and any potential impact will be identified. Therefore, runoff from the <br />reclaimed area should have no significant impact over time on the quality of receiving stream water <br />quality. As a result, post mining land uses which currently occur in the area should not be affected due <br />to the mine plan which has been approved. <br />Summary. The discussion presented herein of the probable hydrologic consequences of the revised <br />mine plan approved by WFC identifies the potential effects of mining. Table 2.05.6(3)-1 summarizes <br />the discussion by listing the probable hydrologic consequences and the results of the analysis of each. <br />As can be seen, all of the probable impacts have been determined to be of a short term nature, of <br />. minimal significance, or a plan has been presented to mitigate those determined to have some <br />significance. As a result, mining and post mining effects to current land uses should be negligible. <br />• (revised 6/01) 2.05.6 (3) - 38 <br />
