Note 2: Based on the NRC staffs independent (deterministic) hazard assessment using present-day regulatory guidance and methodologies of storm surge, the staff concludes that the sites current design basis remains bounded. For this reason, the staff concludes it is appropriate to utilize the current design basis storm surge elevation in conjunction with the mitigating strategies assessment.
