Title	Offsite Notification Due to Inadvertent Emergency Siren Activation
Event Description	On December 30, 2020 at 1550 CST, South Texas Project (STP) received a report that two Emergency Notification System sirens inadvertently actuated. The sirens were heard by residents in the area who contacted the Matagorda County Sheriff's office, which notified the Emergency Response Division at STP of the siren actuation at 1557 CST. Both sirens were initially restored, however siren #24 subsequently actuated again at 1735 CST. Siren #24 has been disconnected. Siren #27 remains available. Thirty-one of thirty-two sirens are available. This notification is being made under 10CFR50.72(b)(2)(xi) as an event where other government agencies were notified. The sirens are no longer alarming. A social media release is planned. The NRC Resident Inspector has been notified of the event. The licensee believes the sirens actuated due to significant rain in the area but will be investigating the cause of the inadvertent actuation.
