• ENERGY FUELS COAL, INC. SOUTHFIELD MINE ANNUAL REPORT OF INFLOWS, DISCHARGES AND CONSUMPTION OF WATER WITHIN THE MINE (JUNE, 1988 THROUGH MAY, 1989) MINE WATER INFLOWS Southfield's Mine water inflows totalled approximately 16,244,000 gallons (49.8 AC-FT) for the period of record of this report (refer to Table 1). The total inflow quantity is based on meter- ed pumping records of water discharged from the 1st North sump via the North Entry Well. The North Entry Well discharges all Mine inflow to the surface water handling and treatment system shown on Figure 2. The 1st North sump is the central collection area for all under- ground mine dewatering systems. In addition, the 1st North sump area receives an undetermined amount of groundwater inflow from fractures. All other mine inflows are collected in sumps developed during the mining sequence and pumped in stages to the 1st North sump. The majority of the total mine inflow is still derived from inflow to the 1st North sump area from fractures and connections to overlying abandoned mine workings. The 1st North sump is inaccessible for monitoring purposes due to unsafe conditions. Because inflow from the underground dewatering system into the 1st North sump is not metered, the 1st North Fracture inflow cannot be reasonable estimated. No significant mine inflow events occurred during the period of record of this report. Inflow and seep locations are shown on Plate 1. As compared to the previous monitoring period (1987 AHR, Plate 1), seep location no. 4 became so insignificant that it is eliminated Erom the map. New inflow/seep locations, designated nos. 6, 8 and 9 developed as a result of mining during the 1988 AHR period of record. Inflow field quality data do not indicate any significant problems or long term trends. Mine water inflow quality monitoring data, obtained at accessable locations, are aummarizec9 on Table 2. InE1ow temperature, electro-conductivity and pH were monitored in compliance with the approved permit. MINE WATER DISCHARGES Mine water discharges to streams occurred at NPDES Discharge Point numbers 001 (Pond No. 1), 003 (Pond No. 2), and 004 (Pond No. 5) totalling approximately 1,434,000 gallons (4.4 AC-FT), shown on Table 3. All discharge points outfall to ephemeral tributaries of Newlin Creek. The total discharge for the period
