• IMPACTS AND FUTURE MONITORING <br />No significant unpredicted adverse impacts were detected from the 1993 water year data. <br />The major influences from the mining operation aze related to dischazges of mine inflow <br />water to the Foidel and Fish Creek drainages. The salt loading impacts on the two creeks <br />were for the most part within the ranges projected in the original probable hydrologic <br />consequences sections of the mine permit application. While total dissolved solids <br />concentrations for the Fish Creek Borehole discharge ranged higher than originally <br />projected during the dewatering activities, the actual flow rates have been equal or lower. <br />Total dissolved solids concentrations and flow rates for the Foidel Creek dischazge are <br />slightly lower than projected, leading to lower salt loadings than projected. <br />Dewatering of the Wadge Overburden close to mined azeas is occurring as projected. <br />However, no significant influences aze apparent in the overlying Twentymile Sandstone <br />or the underlying Trout Creek Sandstone. No apparent influence on groundwater quality <br />is apparent from underground mining operations. <br />~• <br />( • -15- 6/ln/94 1:23 pm <br />
