About San Onofre Nuclear Generation Station (SONGS)

Southern California Edison formally notified the Nuclear Regulatory Commission (NRC) on June 12, 2013 that it had permanently ceased operation of Units 2 and 3 on June 7, 2013. The notification, called a Certification of Permanent Cessation of Power Operations, set the stage for SCE to begin preparations for decommissioning and dismantling the plant.

The San Onofre Nuclear Generating Station (SONGS) is now in the process of decommissioning.  Dismantlement began the first quarter 2020 and will involve the deconstruction of above-grade structures associated with Units 2 and 3 in compliance with NRC requirements, as well as the partial removal of offshore undersea conduits (large pipes) and offshore buoys and anchors.

Emergency Planning

Interjurisdictional Planning Committee

The Interjurisdictional Planning Committee was formed in 1982 to address the emergency planning requirements within the Emergency Planning Zone for the San Onofre Nuclear Generating Station (SONGS).

The Emergency Planning Zone is the area within a 10-mile radius from San Onofre.

  • City of San Clemente
  • City of Dana Point
  • City of San Juan Capistrano
  • Orange County
  • San Diego County
  • Marine Corps Base Camp Pendleton
  • California State Parks
  • Southern California Edison

The mission of this group is to integrate emergency plans, coordinate decision-making for SONGS-related activities and educate the public.
