Note that Entergy Letter NL-1 1-013 also indicated a change to Table RAI-08.1-7 OMA Initiator column to DELETE Zone 54A as an Initiator Zone for the Required OMA of "Locally operate FCV-406A, 406B to control AFW flow to SGs." This change was not made to that table and it has subsequently been confirmed that Zone 54A is an Initiator Zone for this previously requested OMA.
