ONE SIREN IN EP ZONE IS OUT OF SERVICE
"The following event description is based on information currently available. If through subsequent reviews of this event, additional information is identified that is pertinent to this event or alters the information being provided at this time, a follow-up notification will be made via the ENS or under the reporting requirements of 10CFR50.73.
"On July 12, 2006 at approximately 07:30 Mountain Standard Time (MST), the Palo Verde Emergency Preparedness Department reported siren (#23) out of service. Siren #23 is estimated to impact approximately 119 members of population in the emergency planning zone (EPZ) within 5 miles. Palo Verde's reporting criterion is a loss of capability to inform greater than 5% of the population within 5 miles. This call is being placed due to the relatively large segment of the population affected. During an event, the Palo Verde Emergency Plan has a contingency for dispatching Maricopa County Sheriff's Office (MCSO) vehicles with loud speakers to alert persons within the affected area(s) when sirens are inoperable.
"There are no events in progress that require siren operation.
"The NRC Resident Inspector has been notified of the siren 23 being out of service and this ENS call."
The total population within the 5 mile EPZ is 2120.

OFFSITE NOTIFICATION RELATED TO JELLYFISH INFLUX
The licensee was required to secure circulating water pump 26 due to a significant influx of jellyfish. Per the licensee's NPDES (National Pollution Discharge Elimination System) permit, the licensee is required to notify the Maryland Department of Environment of any significant aquatic impact on plant operation. The licensee remained at 100% power throughout and has already restarted the secured circ pump.
The licensee notified the NRC Resident Inspector.
See similar Event Notifications 42699 and 42700.

LOSS OF OFFSITE POWER AT A DECOMMISSIONED FACILITY
The licensee reported a loss of ENS and commercial telephone lines due to a loss of power to the phone switch located offsite from the facility. The call was provided as a courtesy notification and the licensee indicated that cell phone and satellite phone communication were still available. These methods of communication were tested and verified to be working satisfactorily. During the initial notification, it was not made clear to the NRC Operations Center that the facility had lost all offsite power and was operating on backup propane generators. The licensee stated that there were no operability problems onsite and that power was expected to be returned to the phone system within approximately 1 hour.
Update calls were placed to the licensee by the Headquarters Operations Officer at 1930 EDT and again at 2200 EDT to determine phone status. At the 2200 EDT call, it became clear that the site had also experienced a loss of offsite power. The loss of power was due to a tree that had fallen on a power line away from the site and that the licensee did not have any information on when it would be restored. The licensee stated that all onsite power requirements were being met by a backup propane generator and all facility systems (other than the phones) were operable. The licensee stated that the loss of offsite power was not reportable and the loss of the ENS and commercial lines was reportable as information only. The licensee still did not have information on when the power would be restored.
R1DO (Meyer), NMSS EO (Ruland), R1 (Miller) were provided the updated information on the offsite power loss at the site when this information was clarified by the licensee.
* * * RECEIVED AN UPDATE FROM CHRIS POULOS TO JOE O'HARA ON 7/13/06 AT 0155 * * *
The licensee reports that power has been restored to the site and both ENS and commercial phones lines are operating properly.
R1DO (Meyer), NMSS EO (Ruland), R1 (Miller) notified.
* * * UPDATE FROM RALPH COX TO PETE SNYDER ON 7/13/06 AT 1652 * * *
The licensee reexamined the circumstances about this event when it was originally reported and decided to reclassify the original event as a 10 CFR 50.72 (b)(3)(xiii) Loss of Communications / Assessment / Response Capability. The heading information of this report was updated to reflect the licensee's reclassification.
