mine configuration. Case II inflow predictions utilizing the <br /> <br />• maximum coal transmissivity of 1.98 ftZ/day appeared to best <br /> represent the situation currently observed at the mine (Table <br /> 6 of 1994 Greystone Report in Exhibit 6). <br /> There will continue to be a constant inflow of 80 to 100 <br /> gpm associated with the SE-1 TG fault. The mine is currently <br /> using the discharge for underground dust suppression <br /> activities. Should the mine encounter another fault of <br /> comparable magnitude, inflows will increase beyond the current <br /> projection. The station for measuring the flow from the fault <br /> was relocated, and now includes some seepage flow (results in <br /> an apparent increase in fault flow and decrease in area <br /> seepage). The flow from the fault itself may be leveling off <br /> to a sustained production from recharge. <br /> The 1980 WWL Report (Exhibit 6) made a projection that <br /> drawdowns of one foot would be seen at distances ranging from <br /> 4100 - 7700 feet from the perimeter of the mine based on <br /> varying estimates of vertical leakance. The previous mine <br />• inflow analysis indicated that Cases IIB and IIIB reasonably <br /> fit the results observed at the Golden Eagle Mine. Therefore, <br /> new estimates of the drawdown are calculated based on revised <br /> saturated thickness values (Table 7 of 1994 Greystone Report in <br /> Exhibit 6). These estimates suggested that one foot of <br /> drawdown would be evident from 1.7 to 2.1 miles from the <br /> perimeter of the mine. <br /> Concerns about drawdown in the immediate adjacent areas <br /> were quantified through the observation of depths to water in <br /> some holes immediately adjacent to the Golden Eagle Mine <br /> (Figure 6 of 1994 Greystone Report, Exhibit 6). Actual <br /> drawdown in several wells located within 900 feet of the <br /> perimeter of the mine have shown drawdowns as much as 175' at <br /> a distance of 125' from the perimeter of the mine and 13.6' at <br /> a distance of 500' from the perimeter of the mine. <br /> Surface Water Oualitv Chan4es Surface water quality will <br /> be nominally affected by discharge of mine water inflows into <br />• the river, the potential for deep percolation discharge from <br />2.05-38 ([revised oa/2~/9a) <br />
