Title	Offsite Notification to Federal Energy Regulatory Commission
Event Description	At 1345 on 1-10-2005, the Federal Energy Regulatory Commission (FERC) Local Engineer was notified by voice mail message of a failure of the North Anna Spillway Emergency Diesel (1-EE-EG-4) during a surveillance PT. 1-EE-EG-4's voltage regulator would not control voltage. The cause of the failure is unknown at this time. This failure only affects the hydro project and there is no impact on station operation. The FERC notification was made per 18CFR12.10(a). The licensee has notified the NRC Resident Inspector. * * RETRACTION FROM MICHAEL WHALEN TO JEFF ROTTON AT 1200 EST ON 2/7/05 * * * The following information was provided by licensee via facsimile: At 1457 hours0.0169 days <br />0.405 hours <br />0.00241 weeks <br />5.543885e-4 months <br /> on January 10, 2005, a 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> non-emergency notification was made to the NRC Operation Center as a result of an Offsite Notification to other government agency (i.e- FERC due to an inoperable spillway diesel) in accordance with 10 CFR 50.72 (b)(2)(xi). NRC guidance in NUREG -1022, Event Reporting Guidelines 10 CFR 50.72 and 50.73, provides discussion and notification examples intended to set a threshold that ensures reporting when an issue is safety significant. Some notifications to other government agencies may have little or no significance and may not be reportable to the NRC. Although the project safety device was inoperable and therefore reportable to FERC there was no safety significance since normal power was available throughout the time the device was out of service. Based on the discussions in NUREG - 1022, Section 3.2.12 for the notification in question, the North Anna Station Nuclear Safety Operating Committee has determined a NRC Notification was not required because there was no safety significance and is therefore being retracted. The licensee notified the NRC Resident Inspector. Notified R2RDO (Charlie Payne).
