For ten days in July, the daily maximum 24-hour average temperature river temperature was above 30.5 C. In all instances, Sequoyah complied with State of Tennessee NPDES Permit No. TN0026450 (effective date September 1, 200S), Part 1, A. Effluent Limitations and Monitoring Requirements for Outfa\1101, page 2 of 25 bullet 5 which states ,"The daily maximum 24-hour average river temperature is limited to 30.5 C. Since the state's criteria makes exception for ~xceeding the value as a result of natural conditions, where the 24-hour average ambient temperature exceeds 29.4 C and the plant is operated in helper mode (full operation of one cooling tower, at least three lift pumps, per operating unit) the maximum temperature may exceed 30.S C. In no case shall the plant discharge cause the 1-hour average river temperature at the downstream edge of the mixing zone to exceed 33.9 C without the consent of the permitting authority." The below table is provided as a demonstration of when Sequoyah met these requirements of the permit during the month of July. 24-hour 24-hour 24-hour Maximum 1 Maximum 1 Number of average average average Hr average Hr average Cooling downstream ambient ambient Downstream Downstream Tower Lift temperature temperature temperature temperature temperature Pumps in July {Celsius) {Fahrenheit) {Celsius) {Fahrenheit) {Celsius) Service

For two days in August, the daily maximum 24-hour average temperature river temperature was above 30.5 C. In both instances, Sequoyah complied with State ofTennessee NPDES Permit No. TN0026450 (effective date September 1, 2005), Part 1, A. Effluent limitations and Monitoring Requirements for Outfall101, page 2 of 25 bullet 5 which states ,"The daily maximum 24-hour average river temperature is limited to 30.5 C. Since the state's criteria makes exception for exceeding the value as a result of natural conditions, where the 24-hour average ambient temperature exceeds 29.4 C and the plant is operated in helper mode (full operation of one cooling tower, at least three lift pumps, per operating unit) the maximum temperature may exceed 30.5 C. In no case shall the plant discharge cause the 1-hour average river temperature at the downstream edge of the mixing zone to exceed 33.9 C without the consent of the permitting authority." The below table is provided as a demonstration of when Sequoyah met these requirements of the permit during the month of August. 24-hour Number average of downstream 24-hour 24-hour Maximum 1 Maximum 1 Cooling temperature average average Hr average Hr average Tower (Celsius) ambient ambient Downstream Downstream Lift temperature temperature temperature temperature Pumps in August (Fahrenheit) (Celsius) (Fahrenheit) (Celsius) Service

The treatment chemical feed was isolated at 1955. Therefore, the duration of the leak is bounded by a minimum of 65 minutes to a maximum of 185 minutes. A sample of water in the bottom of the catch basin was analyzed and determined to contain 55 ppm total residual chlorine. The permit limit at Outfall 101 is 0.1 ppm chlorine (total residual). No reportable quantity per CERCLA was exceeded. TDEC notification satisfied Federal insecticide, Fungicide and Rodenticide Act (FlFRA) requirements. An estimated 180 to 540 gallons of treated water was spilled. No other chemical release to the Tennessee River occurred. Steps Being Taken to Reduce, Eliminate, and Prevent Recurrence When site emergency responders arrived at 1950 on 8/20/10, a spill response catch basin was placed under the leak location, capturing approximateiy 125 gallons. The strainer water feed was isolated at 2053. At this point, all fiow was terminated. The cause of the leak is being investigated and, once determined, permanent corrective actions will be taken. SR 236979 was written to document the incident and corrective actions. Currently ERCW chemical additions have been temporarily suspended until a full extent of condition including examination of other drain plugs can be completed. A system waik down was completed 8/21/10 to verify proper system alignmant. No misalignments were found. Metallurgical examination of the drain plug is in progress to determine the exact cause of failure. Other Details: No fish distress fish mortality, or abnormal bird migration was observed by site personnel the evening of the event and the morning following. The afternoon of 8/21/10, TVA Biological Resource Staff visually surveyed the near shore area by boat two miles upstream ar.d four miles downstream of the Plant for any signs of dead or dying fish, cr aquatic wildlife. During the investigation, water fowl (two groups of 8 and 6 cf Canada Geese), three Great Blue Herons ar,d tNo Cormorants were observed. No dead or dyir.g fish or affected wildlife was observed in the search area. The opposite shore line was also surveyed to 1/erlf'J any effects of the biocide spill No dead or d:ting fish or affected wildlife was observed.

Dear Mr. Patrick Cromer:

SEQUOYAH NUCLEAR PLANT- DISCHARGE MONITORING REPORT FOR SEPTEMBER 2010 Enclosed is the September 2010 Discharge Monitoring Report for Sequoyah Nuclear Plant. On September 22, 2010 at approximately 2130 EDT, a fire occurred while placing a non-polychlorinated biphenyl (PCB) transformer in service following routine maintenance. As a result of the fire, approximately 13,000 gallons of insulating oil spilled from the transformer into the surrounding gravel switchyard. The secondary containment for the switchyard is the Yard Drainage Pond. A permanent oil skimmer is located on the discharge of the Yard Drainage Pond prior to entry into the Diffuser Pond. TVA mobilized its Emergency Response Team and began recovering the spilled mineral oil. As of today, no oil has been released into Waters of U.S. (e.g., Diffuser Pond). This has been verified by both visual examination and oil and grease analysis. Cleanup continues at both the Yard Drainage Pond and the switchyard where the spill occurred. If you have any questions or need additional information, please contact 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.

Dear Mr. Patrick Cromer:

SEQUOYAH NUCLEAR PLANT- DISCHARGE MONITORING REPORT FOR OCTOBER 2010 Enclosed is the October 2010 Discharge Monitoring Report for Sequoyah Nuclear Plant. Daily 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 10/26/2010 have all yielded results below detection limits for oil and grease. On 10/1/2010 the permit limit for pH at Outfall103 (discharge from the Low Volume Waste Treatment Pond- LVWTP) was exceeded. The pH sampled at 1800 EST on 10/1/2010 was 9.2. The permit limit is 6.0 to 9.0. A sample of Outfall1 01 (Diffuser Pond Discharge to the Tennessee River) was collected at 2116 EST to verify discharge to the river did not exceed limits. The pH of Outfall 101 was within limits at 7.9 pH units. On 10/1/2010 at 2300 EST the pH of Outfall 103 was 9.0 and determined to be back within permit limits. The suspected cause of the exceedances at Outfall 103 was a high pH discharge from the High Crud Tank of the condensate demineralizer system. The pH of the High Crud Tank was approximately 9.0 at the time of discharge to the Turbine Building Sump which discharges to the Low Volume Waste Treatment Pond. The event was documented in the site's corrective action program. Corrective action to date includes the revision of the condensate demineralizer effluent procedure to change the acceptable effluent pH range from 6.0 to 9.0 to 6.0 to 8.0. A study has also been initiated to determine if an engineered pH control system to the LVWTP is a viable option. If you have any questions or need additional information, please contact Stephanie Howard at (423) 843-6700 of Sequoyah's Environmental staff.

Also, enclosed is the revision to the Discharge Number 101 T, Biomonitoring for Outfall 101 for October 2010. 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 11/29/2010 have all yielded results below detection limits for oil and grease. If you have any questions or need additional information, please contact 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.

TN0026450, COMPLIANCE TOXICITY TESTS, NOVEMBER, 2010 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 October 31-November 5, showed no toxic effects to fathead minnows or daphnids. The resulting IC25 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. Call me at (256) 386-2755 if you have any questions or comments following your review of the report. Cynthia L.

22. Notes: Outfall101 samples collected October 31-November 5, 2010, showed no toxic effects to fathead minnows or daphnids.

The resulting ICzs 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. Page2of105

SUMMARY

I CONCLUSIONS Outfall101 samples collected October 31-November 5, 2010, showed no toxic effects to fathead minnows or daphnids. The resulting ICzs 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 Outfall101 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 I 05
