22. Notes: Outfall 101 samples collected August 12 - 17, 2012, 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 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. Page 2 of 99

SUMMARY

/ CONCLUSIONS Outfall 101 samples collected August 12 - 17, 2012, 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 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. Page 11 of 99

Q?t~~ Plant Manager Signatory Authority for: John T. Carlin Site Vice President Sequoyah Nuclear Plant Enclosures cc (Enclosures): Chattanooga Environmental Field Office U.S. Nuclear Regulatory Commission Division of Water Pollution Control Attn: Document Control Desk State Office Building, Suite 550 Washington, DC 20555 540 McCallie Avenue Chattanooga, Tennessee 37 402-2013

TVA Sequoyah Nuclear Plant NPDES Permit No. TN0026450 Attachment 1 Description of the Event and Determination of Cause On 10/19/2012 at 04:25 EDT the Sequoyah (SQN) Shift Manager was notified of a sewage overflow coming from a manhole located on the west side of the SQN Cafeteria. The shift manager initiated the SQN Spill Plan and dispatched personnel to investigate. A slight stream of sewage was discovered flowing out of the manhole ancl running approximately 50 feet down an access road before it reached a yard drain. On 10/19/2012 at 04:40 EDT the sewage overflow was stopped by cycling the number two pump from auto to manual and pumping the manhole down. Preliminary information regarding the overflow was communicated by telephone to the Chattanooga Environmental Field Office on 10119/2012 at 15:03 EDT. The total quantity of sewage which overflowed into a yard drain was estimated at less than 5 gallons. The initial investigation did not reveal any interruptions in power which could have caused the number two pump to trip in the off position. The cause of the overflow was attributed to partial clogging of the number two pump. This manhole is also where the cafeteria grey water enters the sewer system. At this time SQN is in a refueling outage and the partial clogging of the number two pump was caused by increased usage of the sewer system by support personnel and continuous cafeteria usage. All remaining sewage residue in the access road was neutralized with lime. The yard drain flows to the SQN Yard Drainage Pond, which discharges to the Diffuser Pond. The Diffuser Pond discharges through Outfall 101 to the Tennessee River. At no time was there a threat to public drinking supplies, to human health, or the environment. Period of Discharge The shift manager was notified of the overflow on 10/19/2012 at 04:25 EDT. The sewage overflow had just reached the yard drain as personnel responding to the spill arrived. The number two sewage ejector pump was restarted on 10/19/2012 at 04:40 EDT and this action immediately stopped the overflow. and discharge to the yard drain. The estimated time of discharge was less than 15 minutes. Steps Being Ta.ken to Reduce, Eliminate, and Pr~vent Recurrence This incident was entered into the TVA Corrective Action Program. Sequoyah has implemented shiftly monitoring of this sewage ejector location as an added precaution for the remaining duration of the outage to prevent another overflow.

TVA Sequoyah Nuclear Plant NPDES Permit No. TN0026450 Attachment 2 Description of ~he Event and Determination of Cause On 10/27/2012 at 23:00 EDT Sequoyah (SQN) Shift Manager was notified of a high level alarm and a small amount of water coming out of the control panel for the turbine building sewage ejector pump controls. The shift manager initiated the SQN Spill Plan and dispatched personnel to investigate. *On 10/27/2012 at 23:15 EDT a Senior Reactor Operator (SRO) responded to the sewage ejector control panel which did not have any lights indicating sewage ejector pump operation. The sewage water had filled the electrical conduit supplying power to the ejector pumps and was trickling out of the sewage ejector control panel, running down the building w~ll. and into a floor drain. The SRO reset the sewage ejector control panel and the pumps restarted. On 10/27/2012 at 23:30 EDT all sewer water leakage was isolated from the control panel. The total estimated quantity of sewer water which reached the floor drain was estimated at less than 1 gallon. The floor drain flows into the turbine building sump. The turbine building sump is discharged to the Low Volume Waste Treatment Pond which discharges through Internal Monitoring Point 103 to the Diffuser Pond. The Diffuser Pond discharges through Outfall 101 to the Tennessee River. At no time was there a threat to public drinking supplies, to human health, or the environment. Period of Discharge The shift manager was notified of the high level alarm and a small amount of water flowing out of the sewage ejector pump control box on 10/27/2012 at 23:00 EDT. The sewer water was running out of the electrical control panel, traveling down the building wall, and entering the floor drain ~elow. The sewage ejector control box was reset and the pumps restarted. The sewer water flowing out of the control panel was stopped on 10/27/2012 at 23:30 EDT. The estimated time of discharge is approximately 30 minutes. Steps Being Taken to Reduce, Eliminate, and Prevent Recurrence This incident was entered into the TVA Corrective Action Program. An investigation is ongoing to determine the exact cause of the loss of power at the turbine building sewage ejector control panel.

TVA Sequoyah Nuclear Plant NPDES Permit No. TN0026450 Attachment 1 Description of the Event and Determination of Cause On 11/25/2012 at 22:13 EDT the Sequoyah (SQN) Shift Manager was notified of a low-flow sewage overflow coming from a manhole located in the roadway between the Plant Office Building, Multi-Purpose Building, and Security Building. The shift manager initiated the SQN Spill Plan and dispatched personnel to investigate. An intermittent stream of sewage was discovered flowing out of the manhole and running approximately 20 feet across the road before it reached a yard drain. On 11/25/2012 at 22:30 EDT the sewage overflow was stopped from entering the yard drain. All remaining sewage residue in the road was neutralized with lime. The yard drain flows to the SQN Yard Drainage Pond, which discharges to the Diffuser Pond. The Diffuser Pond discharges through Outfall101 to the Tennessee River. At no time was there any observed threat to the public drinking supplies, to human health, or the environment.

  • The total quantity of sewage that overflowed into a yard drain was estimated to be less than 5 gallons. The overflow was caused by a mass of foreign material becoming entangled around the ejector pump float switch. The ejector pump float switch became locked in the high level position and the pump continued to run. The ejector pump eventually tripped du.e to overheating which led to an associated trip of. the high level alarm.

Period of Discharge The shift manager was notified of the overflow on 11/25/2012 at 22:13 EDT. The sewage overflow was entering the yard drain as personnel responding to the spill arrived. The sewage was stopped from entering the yard drain on 11/25/2012 at 22:30 EDT. The estimated time of discharge was approximately 17 minutes. Steps Being Taken to Reduce, Eliminate, and Prevent Recurrence This incident was entered into the TVA Corrective Action Program. Sequoyah continues daily monitoring of sewage ejector pump locations to ensure control power has not been isolated and has added visual inspections of associated manholes to verify the absence of foreign material which may cause ejector pump issues.

TVA Sequoyah Nuclear Plant NPDES Permit No. TN0026450 Attachment 2 Turbine Building Sump Monitoring Data The turbine building sump was discharged directly to the yard drainage pond from 11/10/2012 to 11/15/2012. During this period, the turbine building sump was monitored in accordance with the narrative condition found in Part 1.A.2 of NPDES Permit TN0026450. Parameter Daily Minimum Monthly Average Daily Maximum No. of Samples Flow - 0.480 MGD 1.150 MDG e pH 8 s.u. - 8 s.u. 5 O&G - < 4 mg/L < 6 mg/L 5 TSS - 4 mg/L 7 mg/L 5 Update on Previously Reported Sewage Collection System Overflows SQN is herein providing an update regarding sewage collection system overflow events previously reported to the Division. Each event was entered into the TVA Corrective Action Program, and an investigation was initiated to determine the cause(s). Throughout the investigation and the duration of the Steam Generator Replacement outage, Sequoyah has implemented shiftly monitoring of onsite sewage ejectors as an added precaution. SQN determined the sewage collection system overflows had two apparent causes. The . investigation. indicated there was no consistent method to inform secondary and tertiary electrical-feeds when switching circuit breakers of primary electrical systems. The investigation also indicated there are potential opportunities to improve the inspection program. As a result, TVA will elicit the involvement of a Grade I collection system operator to review the existing system and provide recommendations for necessary upgrades to the material condition and inspection program. The review will include at a minimum an evaluation of current aiarm system design and inspection program scope and frequency. In addition, measures will be taken by site personnel to improve response awareness and ensure prompt _and appropriate actions continue to be taken.

TVA Sequoyah.Nuclear Plant NPDES Permit No. TN0026450 Attachment 1 Description of the Event and Determination of Cause On 12/03/2012 at approximately 19:00 EDT a toilet located in the Mechanical Maintenance shop was observed to be overflowing. The shift manager initiated the SQN Spill Plan and dispatched personnel to investigate. An intermittent stream of sewage was observed overflowing out of the toilet and running approximately 20 feet across the mechanical maintenance shop floor before it entered a floor drain. There were no solids observed in the overflow. On 12/03/2012 at approximately 20:00 EDT the sewage overflow was stopped from entering the floor drain. All remaining sewage residue in the mechanical maintenance shop was neutralized and cleaned up. The floor drain flows to the service building sump. The service building sump is automatically pumped into the SQN Yard Drainage System with discharges to the Yard Drainage Pond. The Yard Drainage Pond discharges to the Diffuser Pond, which discharges through Outfall 101 to the Tennessee River. At no time was there any observed threat to the* public drinking supplies, to human health, or the environment. The overflow was caused by a mass of foreign material becoming lodged in a check valve in the sewage ejector system. The check valve was not able to fully close causing the toilet to overflow as the level in the sewage system increased. Period of Discharge The overflow was observed at approximately 19:00 EDT on 12/03/2012. The sewage overflow was entering the floor drain as personnel responding to the spill arrived. The sewage was stopped from entering the floor drain on 12/03/2012 at approximately 20:00 EDT. The estimated time of discharge was approximately 1 hour. Steps Being Taken to Reduce, Eliminate, and Prevent Recurrence This incident was entered into the TVA Corrective Action Program. Sequoyah has closed the two restrooms in the mechanical maintenance shop until further review of this incident has been conducted. Additionally, plans are being developed to install physical barriers between the restroom and local floor drains that will aide in preventing future overflows from reaching the floor drains.
