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 of Tennessee NPDES Permit No. TN0026450 (effective date September 1, 2005), Part 1, A. Effluent Limitations and Monitoring Requirements for Outfall 101, 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 duringthe month of August.

Attachment Description of the Discharge and Determination of Cause:
At 1350 on 8/20/10, plant security personnel observed a leak adjacent to the Essential Raw Cooling Water (ERCVV) building at the Sequoyah Nuclear Plant (SQN). The pumps in this building transser Tennessee River water into the clant for cooling purposes. The leak was spraying from an outside chemical injection pipe fitting drain plug, overfiowing a small basin, onto concrete, and over a ledge into the Tennessee River. Personnel were dispatched to investigate.
The leak was determined to be treated ERCVV. The chemical used Io treat the ERCW is Towerbrom 9,0, a mixture of sodium dichicroisocyanurate and sodium bromide. The preliminary cause of theleak is the failure of the drain plug due to corrosion.
Period of Discharge:
The chemical feed was initiated at 1350 on 8/20/10 and discovered at 1850 on 8/20/10. 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 basih 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 (FIFRA) 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 approximately 125 gallons. The strainer water feed was isolated at 2053. At this point, all flow 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 walk down was completed 8/21/10 to verify proper system alignment. 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 8/21/1i0, TVA Biological Resource Staff visually surveyed the near shore area by boat tivo miles upstream and four miles downstream of the Plant for any signs of dead or dying fish, or aquatic wildlife. During the investigation, water fow! (two groups of 8 and 6 of Canada Geese), three Great Blue Herons and tMo Cormorants were observed.
No dead or dying fish or affected wildlife was observed in the search area. The opposite shore line was also surveyed to verify any effects of the biocide spill.
No dead or dying fish or affected wildlife was observed.
