On November 30, 2012, the NRC issued the Reference 2 Interim Staff Guidance. Southern California Edison will use the Reference 2 guidance as the approach for developing the NTTF 2.1 Flooding Integrated Assessment Report for San Onofre Nuclear Generating Station (SONGS) Units 2 and Unit 3 if the reevaluated flooding hazard is not bounded by the current design basis flooding evaluation.

Southern California Edison also will use the guidance provided by Reference 3 regarding the trigger conditions and scope of any required Integrated Assessment.
