TN0026450, COMPLIANCE TOXICITY TESTS, MAY, 20 I 0 Per your request, I am only submitting an electronic copy of the subject report. The report provides results of compliance testing using fathead minnows and daphnids. Outfall I 0 I, samples collected May 9-14, showed no toxic effects to fathead minnows or daphnids. The resulting IC25 values for both species were> I 00 percent. Exposure of fathead minnows and daphnids to intake samples resulted in no significant differences from controls during this study period. Fathead minnows were also exposed to UV treated Outfall!Ol and intake samples since fish pathogens present in intake water have been the suspected cause of interference (anomalous dose response and high variability among replicates) in previous toxicity testing at Sequoyah. Call me at (256) 386-2755 if you have any questions or comments following your review of the report. Cynthia L.

22. Notes: OutfalliOI samples collected May 9-14, 2010, showed no toxic effects to fathead minnows or daphnids. The resulting IC25 values, for both species, were >

100 percent. Exposure of daphnids to intake samples resulted in no significant difference from the control during this study period. Minnow growth in the intake samples was significantly lower than the control. Fathead minnows were also exposed to UV treated Outfall I 0 I and intake samples since fish pathogens present in intake water have been the suspected cause of interference (anomalous dose response and high variability among replicates) in previous toxicity testing at Sequoyah. At the time this study was conducted, insignificant mortality occurred in minnows exposed to non-treated and UV treated samples. Page2of99

SUMMARY

I CONCLUSIONS OutfalllOl samples collected May 09-14, 2010, showed no toxic effects to fathead minnows or daphnids. The resulting lCzsl:alues, for both species, were > 100 percent. Exposure of daphnids to intake samples resulted in no significant difference from the control during this study period. Minnow growth in the intake samples was significantly lower than the control. Fathead minnows were also exposed to UV treated OutfalllOl and intake samples since fish pathogens present in intake water have been the suspected cause of interference (anomalous dose response and high variability among replicates) in previous toxicity testing at Sequoyah. At the time this study was conducted, insignificant mortality occurred in minnows exposed to non-treated and UV treated samples. Page 11 of99

Lower and upper PMSD bounds were determined from tbe lOth and 90th percentile, respectively, ofPMSD data ftom EPA's WET Interlaboratory Variability Study (USEPA, 2001a; USEPA, 2001b).
