An important item to mention, is -that the North Dewatering <br />Well will be completely shut by December 31, 1994, with the <br />mine inflow waters diverted down dip into the 2 North Main <br />section. Pipe has been laid into the North 2 Mains and access <br />to the well has been gained. Plumbing the total loop remains <br />to be constructed this month at which time, the North <br />Dewatering Well will be deactivated. Actual numbers for mine <br />discharge will see a dramatic drop as a result, since the <br />water will be rerouted underground and not diverted to the <br />surface and released into the Magpie Creek channel or used by <br />the processing plant as is the current practice. Water taken <br />only from the Corley well will be discharged through the <br />recycling system of Ponds 2 and 3. The permit has been <br />revised with the approval of TR 19 to reflect these changes. <br />III. Surface Water <br />WET testing, creek monitoring, NPDES. <br />A. Total consumptive use of water for the mine was 31.4 acre <br />feet down from 34.4 from the previous year. Permit <br />consumptive use allows for 42 acre feet from the Corley Well, <br />source of the water used. Water consumptive use for the <br />processing plant totaled 17.1 acre feet, same as last year. <br />Water used in raw coal feed decreased from 1992-1993; 38.6 <br />acre feet to 29.6, a difference of 9 acre feet. This was due <br />chiefly to a reduction in coal mined, down from 261,933 tons <br />of clean coal to 239,260 tons. Both belt press reject, and <br />refuse amounts were also subsequently reduced. <br />B. Streamflow sampling <br />EFCI is required to sample stream flow from the following <br />locations: Newlin, Magpie, Oak and Second Alkali Creeks. <br />Data is often difficult to collect due to the ephemeral nature <br />of the creeks. in addition, Second Alkali Creek, under <br />Stipulation 15 requires EFCI to obtain at least one grab <br />sample per year. One sample per creek was obtained in the <br />monitoring period between June 1993 and July 1994. This may <br />be due in part to the extreme drought conditions of the winter <br />and summer months experienced state-wide during this <br />monitoring period. 0.45 cfs were recorded in July 1993 in <br />Second Alkali Creek through extensive effort on EFCI's part <br />therefore, Stipulation 15 has been complied with. 3.34 cfs <br />were recorded in Oak Creek, 4.23 cfs recorded in Magpie Creek <br />and 5.6 cis recorded in Newlin Creek in the period between May <br />and September 1994. The remainder of the year there was no <br />surface water flow. <br />C. Water Quality in Creeks <br />Newlin Creek: TDS, TSS and Ca are all at record lows. <br />Nitrate and bicarbonate levels and SAR are average with other <br />recorded years. Heavy metals are minimal and below material <br />damage criteria. PH is stable. No deterioration of Newlin <br />
