On March 9, 1993, at approximately 2010 MST, Palo Verde Unit 3 was in Mode 1 (POWER OPERATION), operating at approximately 100 percent power when the requirement of Technical Specification Limiting Condition for Operation (TS LCO) 3.8.1.1 ACTION b for one emergency diesel generator i.noperable was not met within the one hour allowed by TS. Between 0200 MST and 0400 MST on March 104 1993, Control Room personnel discovered the missed TS LCO ACTION and subsequently pe formed the surveillance satisfactorily.

The cause of the event was attributed to personnel error. The root cause of the personnel error was indeterminate due to limited information available after five years had lapsed since the event occurred. The NRC initially identified the event in late 1997. The APS investigation surrounding the event was completed by APS on February 10r 1998. The APS investigation determined that an LER was required to be submitted to report the event. As corrective action, appropriate disciplinary action was issued to applicable Control Room personnel.

No previous similar events have been zeported pursuant to 10CFR50.73.
