Only 007 and 008 outfalls discharged during this monitoring period. <br />Quarterly WET Tests were performed on outfalls 007 and 008. Outfa11007 passed the <br />Daphnia Magna yet failed the Fathead Minnow. This letter is also to advise your <br />Department that Western Fuels Colorado will commence a accelerated WET Testing <br />program on outfa11007 as stated in Part L A. 3. c. ii, in Permit Number CO-0000213, <br />"Conduct accelerated testing using the single species found to be more sensitive." The <br />accelerated test results will be forwarded to your Department as they are received. <br />Outfa11008 passed all WET Test parameters without failure. <br />A pH probe failure occurred in the last two weeks of the ls` quarter; therefore no pH <br />readings are available for that time frame. <br />If you have any questions or comments please contact me at 970.864.7590, or email <br />tfry@wfcnucla.org. <br />Sincerely, <br />Thomas D.
