f <br /> <br />l.~ <br />Surface Water - Quality <br />The water quality data show no change or impact from the mine operation. <br />No change ie necessary to the existing program. <br />Surface Pater - Quantity <br />The water quantity data show no change or impact from the mine operation. <br />No changes to the existing program are necessary. <br />!line Water Discharges <br />Water quality data from the monitoring program indicate that total iron <br />and suspended solids concentrations in the discharge water infrequently <br />e:teed the discharge permit effluent limitations. These infrequent <br />exceedancea may be the result of the loss of storage and settling capacity <br />of Pond No. 2 (Discharge Point 003). To correct this and to bring the <br />discharge of mine water to the stream system back to within the effluent <br />limitations. Pond No. 2 should be dredged and its storage capacity <br />increased. This will increase the settling time which may reduce total <br />suspended solids and potentially reduce total iron concentrations in the <br />discharge water. <br />Conclusions <br />The monitoring program as operated can continue and will provide data <br />adequate to monitor the hydrologic impacts of the mine. Pond No. 2 should <br />be dredged and its storage capacity increased. No other changes in the <br />monitoring program are necessary. <br />- 7 - <br />
