SUMMARY <br />Increased salt loading from the Mine No. 1 and Eckman Park discharges have been observed <br />since 1982. They appear to have leveled off starting in 1986. The increased salt loading is <br />predicted and described in the "probable hydrologic consequences" section of the permit <br />document and has been revised during the permit renewal process. Actual observed salt <br />loading in Trout Creek during the irrigation season resulting from surface mining operations <br />has to date been less than that predicted due to the occurrence of attenuating flows from other <br />drainages and has not caused material damage. The total recoverable manganese levels in <br />Foidel Creek are below the stream standard. <br />Localized increases in dissolved solids in the Foidel Creek alluvium have been observed; <br />however, these increases are confined to areas immediately adjacent to the mine and no <br />material damage has or is expected to occur. As predicted, two Wadge Overburden wells <br />have increased dissolved solids levels. This increase is within predicted levels and since there <br />are no water supply wells completed in this aquifer (except by the mines) no material damage <br />has or will occur. No significant impacts have been observed. <br />• <br />L J <br />cycc99 02/14/00 10 <br />
