OFFSITE NOTIFICATION

The following is summary of information provided by the licensee via phone and email:

On November 11, 2024, at 1510 EST, site personnel identified what appeared to be water bubbling up from the pavement adjacent to the sanitary lift station 'C' outside of the facility industrial area. Less than 100 gallons of non-radiological sanitary water ran to a catch basin connected to permitted outfall number 007. Visual inspection did not identify any odor or indication of flow at outfall number 007 discharge. By 1530, the lift station pumps had been secured, sources of influent to the lift station were removed from service, and efforts were underway to pump the tank.

At 1611, an offsite notification was made to the Environmental Protection Agency's Enforcement and Compliance Assurance Division in accordance with Section B of the station's National Pollutant Discharge Elimination System (NPDES) Permit No. 0003557. The event was associated with leakage from underground sewage system piping from a non-radiological underground tank and lift station.

The NRC Resident Inspector will be notified.
