No Discharge this PeriodEPA Form 3320-1 (REV 3199) Previous editions may be usedPage 1 of 1 TVA Sequoyah Nuclear PlantNPDES Permit No. TN0026450Attachment 1Description of the Event and Determination of CauseOn May 19, 2014, at 02:00 EDT at SQN, it was reported that a sewage system manhole wasoverflowing to a nearby yard drain. The manhole is located between the Security/NRC Buildingand the Multipurpose Building. The Shift Manager and Outage Control Center was notified ofthe low-flow sewage overflow and directed sandbags to be placed around yarddrain. Chemistry verified by sight, smell, and fecal coliform analysis that the sewage did enterthe drain. The site estimates that less than five gallons entered the yard drain. Facilitiesremoved a large mass of paper towel from the sewage manhole drainage line. All remainingsewage residue in the road was neutralized with lime. The yard drain flows to the SQN YardDrainage Pond, which discharges to the Diffuser Pond. The Diffuser Pond discharges throughOutfall 101 to the Tennessee River. At no time was there any observed threat to the publicdrinking supplies, to human health, or the environment.Steps Being Taken to Reduce, Eliminate, and Prevent RecurrenceThis incident was entered into the TVA Corrective Action Program. A site wide communicationwas promptly distributed instructing employees to not flush paper towels in the restroomfacilities. Measures are being taken to replace paper towels in the restrooms with air handdryers to minimize potential for recurrence. Sequoyah continues daily monitoring of the sewagemanhole.
