luxe 1998 3 <br />Eonr~~ Fuafe t~crl, Inc. 1997 i4oarn/ X}c~oloBy Report <br />Primary uses of water at the mine are coal preparation and underground dust suppression. <br />Historically, of the total water pumped for use at the mine, approximately 38 percent is <br />rnnsumed in the coal preparation plant, and 27 percent is used for underground dust <br />suppression. The remainder of water use is attributed to pond evaporation and outside dust <br />suppression and equipment washing. <br />Water balance within the mine is a comparison of the consumptive use of the mine and the <br />estimated input and output water in the water handling system., Water pumped into the system <br />from the Corley Mine Well, shown on Table 2, totalled 40.2 ac-ft during the reporting <br />period. The estimated wnsumptive use during the corresponding period was 50.3 x-ft. Water <br />discharged to the stream system was approximately 8.0 ac-fr. This comparison of input, <br />consumptive use, and discharged water quantities illustrates the water balance within the <br />mine. <br />Water discharged to the stream system during the period of this report totalled approximately <br />8.0 ac-ft, as shown an to Table 3. Water discharges were treated and managed through <br />Southfield's surface water handling system depicted on figure 2. Discharges through NPDES <br />outfalls were sampled and reported in accordance with the approved Colorado Wastewater <br />Discharge permit. <br />Water quality data for discharges to streams are summarized on Table 3. A review of these <br />data indicate that all discharges were within NPDF.S permit limitation. Tn addition, all <br />samples submitted for Acute WET testing from Outfall 004 were in compliance. Due to the <br />positive WET test results from previous reporting periods, the Department of Health approved <br />an extended WET test schedule to asemi-annual basis. These data indicate that Southfield's <br />water treatment system effectively reduces the potential of significant impacts to State waters. <br />
