"At 1122 EDT, on October 10, 2019, Duke Energy initiated voluntary notification of North Carolina State and local officials per the guidance in Nuclear Energy Institute (NEI) 07-07, 'Industry Groundwater Protection Initiative - Final Guidance Document,' due to release of tritiated water in excess of 100 gallons.
"On October 8, 2019, at approximately 1300 EDT, Brunswick plant personnel drilling as part of an ongoing site project, damaged a storm drain discharge line. The resulting leak was isolated and water around the impacted area was sampled for gamma emitters and tritium. No gamma emitters were detected. The tritium concentration was below the Environmental Protection Agency (EPA) drinking water limit of 20,000 pCi/L.
"The leak has been stopped and excavation and repair efforts are in progress.
"This notification is being made solely as a four-hour, non-emergency notification for a notification of other government agency. This event is reportable in accordance with 10 CFR 50.72(b)(2)(xi).
"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."
