Thy l~nCr~ft Group <br />~~~~~~~ <br />An Environmental Services Company <br />September 23, 2004 <br />Mr. Henry Bazbe <br />Mountain Coal Company <br />P.O. Box 591 <br />Somerset, Colorado 81434 <br />Deaz Mr. Bazbe: <br />RF~F~VEO <br />NOY ~l 2004 <br />Oiy'sion of Mi~,.~s 8 ~~'o%yY <br />Enclosed is the report for the acute tests performed for Mountain Coal Company on the West Elk <br />Mine discharge site. There was toxicity seen to the Daphnia magna species; therefore, further <br />accelerated testing with this species will be required. <br />In the Fathead minnow test there was no toxicity detected at any effluent concentration. The <br />sample passes WET (whole effluent toxicity) requirements for this species. <br />As with previous tests for the West Elk Mine dischazge, tests were performed on treated and <br />untreated samples of the effluent. The tests appeared to corm that TDS (mainly in the form of <br />high alkalinity) is the only source of toxicity in the 017 dischazge. <br />If you have any questions or concerns, please do not hesitate to contact me at (303) 661-9324. <br />Best regards, <br />-_ <br />Amy D. de la Chica <br />Senior Scientist <br />Enclosure(s): Report <br />Invoice <br />1341 Cannon Street • Louisville, Colorado 80027 • 303-661-9324 • Fax 303-661-9325 <br />
