<br />The last several dry years have brought about gradual increases in <br />TDS levels. Discharges from Sedimentation Pond 003 have shown <br />increases in magnesium and sulfate. This appears to be a result <br />of the truck washing station runoff. Waters in the upper Fish Creek <br />drainage have shown consistent increases in TDS levels. While this <br />increase is largely a result of increased mine disturbance, there <br />appears to be natural contributions to these higher levels. Water <br />in the Bond Creek-Fish Creek confluence show gradual increases in <br />TDS levels. This fact can apparently be attributed to increasing <br />mining disturbances. <br />Mixing and dilution appear to largely mitigate TDS loading of waters <br />from the mine site area. No exceedences were noted from NPDES <br />discharge sites from 1988. It appears that the Seneca II Mine is <br />operating within acceptable guidelines. Its impacts on the surrounding <br />and regional hydrologic area appear to be very small. <br />JMC/eke <br />1444E <br />
