| Title | Offsite Notification Due to Oil Sheen on the River |
| Event Description | On 5/24/2012 at 1541 EDT, a notification to the National Response Center was made after the discovery of a visible oil sheen on waters of the U.S. (the Tennessee River side of Sequoyah's intake forebay skimmer wall). The source of the oil appears to be a tipped or overflowing catchpan located in the Essential Raw Cooling Water (ERCW) pumping station. All catchpans in the pumping station have been emptied to eliminate them as immediate potential source of oil released to the environment.
The following agencies have also been notified: EPA Region 4, and the Tennessee Emergency Management Agency (TEMA). The Tennessee Department of Environment and Conservation (TDEC) will be notified. Cleanup is in progress. Measures to prevent recurrence are being taken. The NRC Resident Inspector will be notified. |
