Because of the uncertainty of flows a sample was not obtained during the <br />2"a calender quarter. However a sample was obtained on July 8, 2002 to serve as the 2"a <br />quarter effluent sample. A copy of the Colorado form -- CDPS Wet Test Report Form - <br />Acute is attached as required. Test results indicate that the effluent was not acute]y toxic <br />to fathead minnow survival <br />If available, an additional 3`a quarter effluent sample will be obtained from outfall 011. <br />If you have any questions, please contact me at (970) 929-5806. <br />/~~Ll,~i~..z.a ~ . ~ Xv~ <br />/ 'll <br />'James A.
