In either case, the mine <br />is not expected to have a significant effect on quantity or <br />quality. Triere is little ground water associated with strata <br />within or 'near the mine zone. Early in the operation, minor <br />inflows were experienced from the saturated portion of the Cameo <br />Seam and from the east fault. The portion of the 1.6 gpm inflow <br />that originated from McClane Creek and flowed into the mine along <br />the east fault is insignificant in comparison with the flow in the <br />ephemeral drainage during snowmelt or after major storms. The flow <br />which originates in the Cameo Seam is insignificant in comparison <br />with the quantity of water stored in the general area of the Cameo <br />seam or with the recharge capacity into the seam. <br />Surface Water <br />The quality of water discharged from the mine is generally the same <br />or better than water quality in East Salt Creek at the confluence <br />with McClane Creek. Therefore, no detrimental impact on surface <br />water quality downstream of the permit area is expected. <br />me\ahrsumry.mem <br />
