i , ' Energy Fuels Coal, Inc Southfield Mine ANNUAL REPORT OF INFLOWS, DISCHARGES AND CONSUMPTION OF WATER WITHIN THE HINE ' 1992 AHR 1. Mine Inflows Hine inflow quantity for the Southfield Hine during the 1992. AHR reporting period is estimated at 62.4 AC-FT. This figure is based on the combined total of water discharged from the North, Entry Well (25.8 AC-FT), shown on Table 1, and underground water flow into abandoned mine areas in the west section of the mine (36.6 AC-FT). Mine inflow and seep locations were monitored on several' occasions during the reporting period on an opportunistic basis.' Inflow locations, where accessible, were monitored for flow and' quality data. All mine inflow and seep monitoring data is presented on Table 2; each location keyed to a current mine map attached as. . Plate 1. The locations shown on the map are generally consistent with those documented on previous AHR's. A new seep for this reporting period is apparent at the north end of the mine (location no. 11) which has developed during the recent mining of this area. A review of the data contained in Table 2 indicates that mine inflow quality is consistent with inflow data presented in previous reporting periods for those areas persisting for several years.; Estimated total mine inflow, 62.4 AC-FT, is nearly double that of the previous reporting period's 34.6 AC-FT. The increase may be attributed to both the unusually heavy summer rainfall (12.1 inches during August, 1992) and the continuous duration of inflow in the west section of the mine. 2. Discharges to Streams Water discharged to the stream system totalled 24.6 AC-FTi during the period of this report (refer to Table 3). All water' discharged is .treated and managed by Southfield'e surface water handling system depicted on Figure 2. Discharge events are sampled .and reported in accordance with the approved wastewater discharge's permit. Water quality data for discharges to streams are summarized on Table 3. A review of these data indicate that all discharges werei within NPDES permit limitations, including the samples submitted. for Acute WET testing. These results suggest that the current water. • treatment system effectively reduces the potential of aignificantl impacts to State waters. ~, '; ii ;
