Diablo Canyon Power Plant Decommissioning

Diablo Canyon Power Plant Decommissioning: Notice of Availability – Draft Environmental Impact Report

In 2021, PG&E filed a Land Use Permit application (DRC2021-00092) for the planned decommissioning of its Diablo Canyon Power Plant (DCPP), a two-unit nuclear power plant on the Central Coast near Avila Beach.

While the Environmental Impact Report (EIR) for the proposed DCPP decommissioning project was being prepared, Governor Gavin Newsom signed SB 846 (Dodd, 2022) into law, providing PG&E a path to continue operating the DCPP through 2030. Given that the path to extended operations is not guaranteed, PG&E requested that the County continue preparation of the EIR and permitting of its proposed decommissioning project.

On July 28, 2023, the Draft EIR for the DCPP Decommissioning Project was released for 60-day public review. The Notice of Availability can be accessed here.

The County is requesting the public provide written comments to the Draft EIR during the comment period, which will begin on July 28 and end at 5:00 p.m. on September 25, 2023. Comments will not be accepted after the 5:00 p.m. deadline. Please email comments directly to [email protected]. Comments may also be mailed to Susan Strachan, San Luis Obispo County Department of Planning & Building, 976 Osos St., Rm 300, San Luis Obispo, CA 93408.
