I collected a small sample for field tests of <br />pH, temperature and conductivity, and planned on taking a larger sample for a <br />complete monthly surface water suite plus the quarterly acute WET test the next day. <br />However, when I returned to take that larger sample, the site had ceased discharging, <br />and it did not discharge again during the quarter. 1 estimate that about 72,000 gallons <br />of water were released through the outfall. <br />Since the water released came from pit inflows that sourced from our upper highwall, <br />and that the source was located a short distance (<300 feet) from an active irrigation <br />ditch, I believe the water discharged from the outfall was of similaz or better quality <br />that what was dischazged from our normal mine outfall, Outfall 007. Outfall 007 was <br />in compliance during the 4th quarter of 2000. <br />In the future, when Outfall 008 discharges, a sample will be immediately collected for <br />the field test, the monthly lab surface water suite and a acute WET test. That way, if <br />the site does not discharge again for the quarter, the otF[fall will remain incompliance. <br />Please give me a call if you have any questions. <br />Sincerely, <br />`~ .,~ <br />Tony dins <br />Mine gineer <br />
