Dear Ms. Morgan:

TENNESSEE VALLEY AUTHORITY (TVA) - SEQUOYAH NUCLEAR PLANT (SQN) - NPDES PERMIT NO. TN0026450 - DISCHARGE MONITORING REPORT (DMR) FOR OCTOBER 2012 Enclosed is the October 2012 Discharge Monitoring Report for Sequoyah Nuclear Plant. The turbine building sump (TBS) discharged directly to the yard drainage pond during the reporting period and was monitored in accordance with the narrative condition found in Part 1 .A.2. of the subject permit.

Enclosed is TBS monitoring data as well as attachments describing two collection system overflows that occurred during the reporting period. At no time was there a threat to public drinking supplies, to human health, or the environment.

If you have any questions or need additional information, please contact Brad Love by email at bmlove@tva.gov or by phone at (423) 843-6714.

TVA Sequoyah Nuclear Plant NPDES Permit No. TN0026450 Attachment I 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 and 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 10/19/2012 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 I 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 04:25EDT. 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 Taken to Reduce, Eliminate, and Prevent 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 the 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 wall, 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 10/27/20.12 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 below. 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. Sequoyah has implemented shiftly monitoring of this sewage ejector location as an added precaution until the apparent cause has been identified and repaired to prevent another overflow. An update on the apparent cause will be provided in the November DMR submittal.

TVA Sequoyah Nuclear Plant NPDES Permit No. TN0026450 Attachment 3 The turbine building sump was discharged directly to the yard drainage pond on 10/24/2012 and 10/28/2012 - 10/31/2012. 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.
