AB 734 California Assembly · 2025-2026 Regular Session

Environmental protection: biological resources data: State Energy Resources Conservation and Development Commission: powerplants: power lines: applications.

Summary
Existing law vests the State Energy Resources Conservation and Development Commission with the power to certify locations on which an electrical transmission line or thermal powerplant is constructed, or is proposed to be constructed, except as provided. Existing law authorizes the commission to exempt from certification a thermal powerplant with a generating capacity of up to 100 megawatts, and modifications to existing generating facilities that do not add capacity in excess of 100 megawatts if the commission finds that no substantial adverse impact on the environment or energy resources will result from the construction or operation of the proposed facility or from the modifications. This bill would require any biological resources data submitted to the commission in an application for certification or small powerplant exemption pursuant to the above-described provisions to be made publicly available on the commission's docket as part of the certification proceeding unless the Department of Fish and Wildlife makes a written determination that the data to be made public includes specified location data, the disclosure of which would pose a significant risk to individuals of the species. The bill would require the department, if it makes that determination, to include in the written determination an assessment of the maximum amount of the specified data that can be released without posing a risk to the species. The bill would require the department to provide its written determination to the commission and would require the commission to make the data, in accordance with the determination, available to the public on the commission's docket. Existing law, until June 30, 2029, authorizes a person proposing an eligible facility, including a solar photovoltaic or terrestrial wind electrical generating powerplant with a generating capacity of 50 megawatts or more, to submit an application with the commission for certification of the site and related facility. This bill would apply the same public availability requirements described above to biological resources data submitted to the commission as part of an application for certification of an eligible facility.

04/21/25 - Amended Assembly 09/05/25 - Enrolled · 4 edits · Sep 5, 2025
MODERATE
The enrolled version of AB 734 significantly narrowed the bill's scope by removing a provision that would have required all regional, local, and state public agencies to post biological resources data on their websites within two weeks of submission. The final bill now only requires the State Energy Resources Conservation and Development Commission to make such data available on its docket for powerplant certification proceedings. This also eliminated the state-mandated local program reimbursement provision that was tied to the broader requirement.
SCOPE

Removed new Section 71068.5, which would have required any regional, local, or state public agency receiving biological resources data to post it on its internet website within two weeks of submission. This was the most significant substantive change, narrowing the bill from a broad transparency mandate across all public agencies to one limited to the Energy Commission's certification dockets.

Section 25544(b) was narrowed from requiring biological resources data submitted to any public agency to be posted on that agency's website and made available within two weeks, to only requiring data submitted to the commission as part of certification or exemption applications to be made available on the commission's docket.

FISCAL

Removed the state-mandated local program reimbursement provision (former SEC. 2) that would have required the state to reimburse local agencies and school districts for costs mandated by the bill, as determined by the Commission on State Mandates. This became unnecessary once the broad local agency requirement was eliminated.

TECHNICAL

Assembly Member Caloza was removed as co-author in the enrolled version.
