LRA question Perry, Attached is a page from Attachment B of the Entergy Letter that docketed LRA Amendment 3 (dated July 5, 2006). I believe this may address the issue you raised this morning about item 3.1.1-55 in LRA Table 3.1.1 on page 3.1-30 and Table 3.1.2-3 on page 3.1-72. We can discuss when you have a chance.

Thanks, Ed Sanchez Pilgrim Licensing
