| ENS 54145 | 3 July 2019 15:24:00 | At 1026 CDT on July 3, 2019, the National Weather Service notified the South Texas Project (STP) that the Bay City NOAA radio transmitter was out of service. This affects the tone alert radios used to notify the public in the event of an emergency condition. This condition impacts the ability to readily notify a portion of the Emergency Planning Zone (EPZ) population for the STP Electric Generating Station. The loss of the alert radio system meets the reporting criterion for 10 CFR 50.72(b)(3)(xiii). The Matagorda County alert sirens, which are also part of the Public Prompt Notification System, remain operable. Compensatory measures have been verified to be available should the Prompt Notification System be needed. These measures consist of a reverse 911 system available from Matagorda County as well as local law enforcement personnel who would perform route alerting for the affected areas of the EPZ. The event has been entered into the Corrective Action Program and the NRC Resident Inspector has been notified. A return to service time for the radio transmitter is not currently available. Matagorda County was also notified by the National Weather Service and STP. This meets the reporting requirement for notification of an offsite agency, 10 CFR 50.72(b)(2)(xi).
At 1321 CDT, the National Weather Service communication tower was returned to service. South Texas Project verified that the automatic notification radios have been returned to service. The licensee has notified the NRC Resident Inspector. Notified R4DO (Haire). |
