Licensee Comments:

3Q/08: Emergency AC Train A planned unavailability for June 2008 is revised from a value 2.39 hours to 2.87 hours and Train B unavailability for June 2008 is revised from a value of 2.17 hours to 2.60 hours resulting from an internal review. These changes do not result in a threshold color change.
