Diablo Canyon Power Plant Decommissioning

On August 31, 2022, the California State Legislature passed Senate Bill 846, co-authored by Senator Bill Dodd and Assemblymember Jordan Cunningham. The legislation seeks to extend operations at Diablo Canyon Power Plant (DCPP) up to 2030. The Governor is expected to sign this Senate Bill into Law.

The County of San Luis Obispo has been actively engaged in the state legislative process regarding the future of DCPP. As the host community for the plant, the County continues to work with federal, state, and local partners to plan for the future of DCPP. The plant plays a significant role in the County’s economy and community, and the County is working to ensure the community’s interests are represented in the safety, environmental, and other regulatory processes and decisions that lie ahead.

San Luis Obispo County Decommissioning Activities

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 would have ceased operating upon the expiration of the Unit 1 and Unit 2 operating licenses, in November 2024 and August 2025, respectively.

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.  PG&E’s application materials can be accessed using the link below, or by using the link within the CSS User Guide.
