Diablo Canyon Power Plant Decommissioning
In 2016, PG&E decided not to renew the Nuclear Regulatory Commission licenses for the Diablo Canyon Power Plant (DCPP). The California Public Utilities Commission approved the plant’s retirement in 2018. As a result, the power plant will cease operating upon the expiration of the Unit 1 and Unit 2 operating licenses, in November 2024 and August 2025, respectively.
PG&E then intends to begin decommissioning the power plant. PG&E submitted a land use permit application to the County in March 2021 for the decommissioning effort. An application supplement was submitted by PG&E on July 8, 2021, in response to the County’s request for additional application information. A third application filing was submitted by PG&E on October 6, 2021, responding to additional County comments. On October 27, 2021, the County accepted PG&E’s application, thus initiating the environmental review process pursuant to the California Environmental Quality Act.
The DCPP Decommissioning Project application files in CSS have been re-named using a prefix system that enables sorting of the files into chronological order, grouped by PG&E and County.
A User Guide titled “1. CSS USER GUIDE” has been uploaded to the CSS, along with a File Index titled “2. CSS APPL FILE INDEX”, intended to assist the public with identifying the application files in CSS. The File Index provides the new file name with prefix, the previous file name, and additional reference information on file content. The User Guide can be accessed here: DRC2021-00092 CSS User Guide (sloplanning.org). PG&E’s application materials can be accessed using the link below, or by using the link within the CSS User Guide.

Notice of Public Meeting
Diablo Canyon Power Plant Decommissioning Engagement Panel to meet on May 25, 2022
The Diablo Canyon Decommissioning Engagement Panel will meet on May 25, 2022 to continue discussion of Spent Nuclear Fuel Management and Storage. The Panel met on April 20, 2022 and received a report from PG&E on the status of the current Independent Spent Fuel Storage Installation (ISFSI) and the selection of Orano TN as the contractor for the transfer of all remaining spent nuclear fuel to dry casks storage using its NUHOMS EOS dry cask storage system. The Engagement Panel solicited public comment on the new dry cask storage system in preparation for its May 25 meeting where PG&E and Orano TN will provide more detailed information regarding the new system.
On October 28, 2021, the County issued a Notice of Preparation, which is a notice for soliciting agency, organization, and public input and initiation of scoping for the preparation of an Environmental Impact Report (EIR) for the DCPP Decommissioning Project. The Notice of Preparation can be accessed here.
The County held five (5) virtual EIR scoping meetings to enable agencies, organizations, and interested members of the public to obtain information about the project, ask questions, and provide oral comments on the scope and content of the EIR.
