REDUCTION IN EMERGENCY PREPAREDNESS CAPABILITY

"On February 24, 2007, at 1820 hours, 13 of 51 alert sirens in the Quad Cities Station Emergency Planning Zone were determined to be inoperable. This is considered a major loss of the Quad Cities offsite notification capability. The alert sirens were disabled due to a loss of power. Power was lost due to a major winter storm in the area. Repairs are in progress at the time of this notification. This report is being made due to the reduction in public notification capabilities in accordance with 10CFR50.72(b)(3)(xiii)."

He licensee notified the NRC Resident Inspector, and will be notifying the State.

* * * UPDATE AT 2006 ON 02/26/07 FROM JIM STORTZ TO W. GOTT * * *

This is a follow up notification to report that only 4 sirens remain inoperable with no estimated time of repair due to downed poles and high voltage power lines on the ground. This is also to correct the number of alert sirens available in the Quad Cities Station Emergency Planning Zone. There are 52 sirens not 51 reported in the original report. With 48 of the 52 alert sirens operational, the station no longer meets the reporting criteria.
