Dear Mr. Patrick Cromer:

SEQUOYAH NUCLEAR PLANT-DISCHARGE MONITORING REPORT FOR APRIL 2011 Enclosed is the April 2011 Discharge Monitoring Report for Sequoyah Nuclear Plant. Sample collection continues at the Diffuser Pond Inlet of the Yard Drainage Pond effluent because of a transformer oil spill that reached the Yard Drainage Pond. Samples collected from 9/23/2010 through 4/30/2011 have all yielded results below detection limits for oil and grease. If you have any questions or need additional information, please contact Brad Love at (423) 843-6714 or Stephanie Howard at (423) 843-6700 of Sequoyah's Environmental staff. I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted.

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.

ttsamples were collected in two 2.5 gallon cubitainers and one 5 gallon cubitainer. Temperature was measured in each cubitainer upon arrival.

4. Sample Manipulation: Samples from Outfalll01 and intake were warmed to test temperature (25.0 +/- 1.0°C) in a warm water bath.

Page 3 of 100 Aliguots ofOutfalliOI and Intake samples were UV-treated through a 40-watt Smart UV Sterilizer (manufactured by Emperor Aquatics. Inc.) for 2 minutes.

SUMMARY

I CONCLUSIONS OutfalllOI samples collected May 01-06,2011, showed no toxic effects to fathead minnows or daphnids. The resulting IC25 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 I 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. Page 11 of 100

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 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.

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)

1. Test Type: 7-day chronic tests with results expressed as IC25 values in giL KCl or NaCl.
2.

Standard Toxicant: Potassium Chloride (KCl crystalline) for Pimephales promelas. Sodium Chloride (NaCl crystalline) for Ceriodaphnia dubia.

3. Dilution Water Used: Moderately hard synthetic water.
4.

Statistics: ToxCalc software Version 5.0 was used for statistical analyses. Page 13 of 100
