Decommissioning Timeline
Key Milestones
California Coastal Commission unanimously approves Coastal Development Permit, clearing the way for dismantlement and decontamination to proceed.
SCE issues Notice of Deconstruction to 12,000 residents living within a 5-mile radius of SONGS.
California Department of Public Health - Radiologic Health Branch publishes data from the SONGS ISFSI radiation monitoring system for the first time.
California Coastal Commission unanimously approves Inspection and Maintenance Program for the Holtec UMAX spent fuel storage system at SONGS.
All spent nuclear fuel at San Onofre is placed in dry storage. The site switches to an "ISFSI-only" license that essentially means the nuclear focus is reduced to the spent fuel storage installation. The majority of San Onofre becomes an industrial deconstruction site, with critical functions, including oversight, focused on the safe dismantlement of plant structures.
