The report provides results of compliance testing using fathead minnows and daphnids. Outfall 101, samples collected February 8-13, showed no toxic effects to fathead minnows or daphnids. The resulting IC 25 values for both species were> 100 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 101 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.

TVA Contact: Cynthia L. Russell Phone#: (256) 386-2755 22. Notes: OutfalllOl samples collected February 8-13, 2009, showed no toxic effects to fathead minnows or daphnids.

The resulting IC 25 values, for both species, were> 1 00 percent. Exposure of minnows and daphnids to intake samples resulted in no significant difference from the controls during this study period. Page 2 of98 Fathead minnows were also exposed to UV treated Outfall 1 01 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. METHODS

SUMMARY

I CONCLUSIONS Page 11 of 98 Outfall101 samples collected February 8-13,2009, showed no toxic effects to fathead minnows or daphnids. The resulting IC 25 values, for both species, were > 100 percent. Exposure of minnows and daphnids to intake samples resulted in no significant difference from the controls during this study period. Fathead minnows were also exposed to UV treated Outfall 101 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. Appendix A ADDITIONALTOXICITY TEST INFORMATION

SUMMARY

OF METHODS 1. Pimephales promelas Tests were conducted according to EPA-821-R-02-013 (October 2002) using four replicates, each containing ten test organisms, per treatment. Test vessels consisted of 500-mL plastic disposable cups, each containing 250-mL of test solution.

2. Ceriodaphnia dubia Tests were conducted according to EPA-821-R-02-013 (October 2002) using ten replicates, each containing one test organism, per treatment.

Test vessels consisted of 30-mL polypropylene cups, each containing 15-mL of test solution. DEVIATIONS I MODIFICATIONS TO TEST PROTOCOL 1. Pimephales promelas None 2. Ceriodaphnia dubia None DEVIATIONS I MODIFICATIONS TO PRETEST CULTURE OR HOLDING OF TEST ORGANISMS

Biomonitoring samples are preserved by storing them at 6°C and shipping them in ice. The hold time for each sample is 36 hours from the time of collection. Therefore, please collect and ship in such a way that the laboratory will receive the samples with ample time to initiate testing within that time frame. Samples shipped overnight on Friday via FedEx or UPS must be marked for Saturday delivery or they will not arrive Monday.

TN0026450, COMPLIANCE TOXICITY TESTS, MAY, 2009 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. Outfall101, samples collected May 10-15, showed no toxic effects to fathead minnows or daphnids. The resulting IC 25 values for both species were> 1 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 101 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.

TV A Contact: Cynthia L. Russell Phone #: (256) 386-2755 22. Notes: Outfall101 samples collected May 10-15,2009, showed no toxic effects to fathead minnows or daphnids.

The resulting IC 25 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 survival was significantly reduced when exposed to intake samples during this study period. Page 2 of 107 Fathead minnows were also exposed to UV treated Outfall 101 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.

SUMMARY

I CONCLUSIONS Page 11 of 107 Outfall 101 samples collected May 10-15, 2009, showed no toxic effects to fathead minnows or daphnids. The resulting IC 25 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 survival was significantly reduced when exposed to intake samples during this study period. Fathead minnows were also exposed to UV treated Outfall 101 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. Appendix A ADDITIONAL TOXICITY TEST INFORMATION

SUMMARY

OF METHODS 1. Pimephales promelas Tests were conducted according to EPA-821-R-02-013 (October 2002) using four replicates, each containing ten test organisms, per treatment. Test vessels consisted of 500-mL plastic disposable cups, each containing 250-mL test solution.

2. Ceriodaphnia dubia Tests were conducted according to EPA-821-R-02-013 (October 2002) using ten replicates, each containing one test organism, per treatment.

Test vessels consisted of 30-mL polypropylene cups, each containing 15-mL of test solution. DEVIATIONS I MODIFICATIONS TO TEST PROTOCOL 1. Pimephales promelas None 2. Ceriodaphnia dubia None DEVIATIONS I MODIFICATIONS TO PRETEST CULTURE OR HOLDING OF TEST ORGANISMS

2 .. Instruments: All identification, service, and calibration information pertaining to laboratory instruments is recorded in calibration and maintenance logbooks.

3. Temperature was measured by SM 2550 B. 4. Dissolved oxygen was measured by SM 4500 0 G. 5. The pH was measured by SM 4500 H+ B. 6. Conductance was measured by SM 2510 B. 7. Alkalinity was measured by SM 2320 B. 8. Total hardness was measured by SM 2340 C. 9. Total residual chlorine was measured by ORION Electrode Method 97-70. QUALITY ASSURANCE Toxicity Test Methods: All phases of the study including, but not limited to, sample collection, handling and storage, glassware preparation, test organism culturing/acquisition and acclimation, test organism handling during test, and maintaining appropriate test conditions were conducted according to the protocol as described in this report and EPA-821-R-02-013.

Any known deviations were noted during the study and are reported herein. REFERENCE TOXICANT TESTS (See Appendix D for control chart information)
