Diablo Canyon Power Plan Decommissioning Project

Diablo Canyon Power Plan Decommissioning Project

The Proposed Project involves the decommissioning of the Diablo Canyon Power Plant (DCPP), including Phase 1 decommissioning activities and Phase 2 soil remediation, final status surveys, and site restoration. The Project involves three different sites: (1) the Diablo Canyon Power Plant (DCPP) site, (2) the Pismo Beach Railyard (PBR), and (3) the Betteravia Industrial Park Santa Maria Valley Railyard Facility site (SMVR-SB). The Osburn Yard in the City of Santa Maria (SMVR-SM) is no longer under consideration and is not part of the Proposed Project. The DCPP site is on the coast of San Luis Obispo County, California, approximately 7 miles northwest of Avila Beach. The DCPP facility comprises a 750-acre high-security zone surrounded by an approximately 12,000-acre area of land owned by either PG&E or Eureka Energy, a wholly owned subsidiary of PG&E. The rail sites would be used to transfer decommissioning waste from trucks to rail cars, where the waste would then be transported by rail to out-of-state disposal facilities (Clive, Utah and/or Andrews, Texas). The PBR site is currently used by PG&E for equipment and material storage and transportation needs in support of DCPP operations. The site is located at 800 Price Canyon Road in the City of Pismo Beach in San Luis Obispo County, approximately 13 miles southeast of the DCPP site. This site would be used as a contingency for the transfer of non-radioactive and non-hazardous decommissioning waste. The SMVR-SB site is in the County of Santa Barbara (2820 W. Betteravia Road). PG&E proposes to retain the existing Eastern and Western Breakwaters and Intake Structure as well as other facilities for potential future use by others. The structures that would remain on site related to the Independent Spent Fuel Storage Installation and Greater than Class C (GTCC) storage facility would continue to be managed by PG&E within a designated owner-controlled area until an off-site interim storage facility or permanent repository is available. Identification of an off-site repository for long-term storage of spent nuclear fuel and GTCC waste is a concern both for DCPP and for nuclear power facilities across the nation and awaits resolution by the federal government.
