• Additional 'contributions to the impounded water (dominated by spoil water quality) as a <br />result of snowmelt runoff from reclaimed areas will result in some dilution of pond water <br />and corresponding pond discharge chemistry, depending on the magnitude and duration of the <br />snowmelt. Runoff generated by rainfall on reclaimed areas will have less of an effect on <br />pond or pond discharge chemistry due to lower runoff volumes in comparison to snowmelt. <br />The effects of runoff from reclaimed areas on surface water quality will be long-term, but <br />of minimal significance. Runoff water quality will be influenced by topsoil mineralogy, <br />and will exhibit lower TDS and major ion concentrations than impounded water dominated by <br />re sa turated spoil water chemistry. Runoff from reclaimed areas will be greater during the <br />snowmelt period (spring, early summer), and will potentially provide a temporary dilution <br />of impounded and pond discharge water. <br />Summary <br />This Tab has presented a discussion of probable hydrologic consequences expected to result <br />from the mine plans presented in this PAP. Table 17-29 summarizes the discussion by <br />• listing the probable hydrologic consequences and the results of each analysis. As <br />presented in the table, all of the probable impacts have been determined to have no short- <br />or long-term significance, or a pl an. has been presented to mitigate those determined to <br />have some significance. <br />J <br />77 <br />
