AB 1373 California Assembly · 2025-2026 Regular Session

Water quality: state certification.

Summary
Under existing law, the State Water Resources Control Board and the California regional water quality control boards prescribe waste discharge requirements in accordance with the Federal Water Pollution Control Act and the Porter-Cologne Water Quality Control Act. Under federal law, any applicant seeking a federal license or permit for an activity that may result in any discharge into the navigable waters of the United States is required to first seek a state water quality certification, as specified. The Porter-Cologne Water Quality Control Act authorizes the state board to certify or provide a statement to a federal agency, as required pursuant to federal law, that there is reasonable assurance that an activity of any person subject to the jurisdiction of the state board will not reduce water quality below applicable standards. The federal act provides that if a state fails or refuses to act on a request for this certification within a reasonable period of time, which shall not exceed one year after receipt of the request, then the state certification requirements are waived with respect to the federal application. This bill would require the state board, if requested by the applicant within 14 days of an initial draft certification being issued, to hold a public hearing at least 21 days before taking action on an application for certification for a license to operate a hydroelectric facility, as provided. The bill would, if a public hearing is requested on the draft certification, prohibit the authority to issue a certification for a license to operate a hydroelectric facility from being delegated. The bill would authorize the state board to include in its fee schedule for hydroelectric facility applicants an amount up to the reasonable costs incurred by the state board in implementing these provisions.

What changed between versions

09/16/25 - Enrolled AB1373 · 1 edit
MINOR
No substantive policy changes exist between these two versions. The diff reflects only a change in presentation format: the 'from' version is the formal enrolled bill document with signature blocks and page numbers, while the 'to' version is a web-based rendering of the same text from the California legislature website, complete with navigation menus and site elements. The actual legislative language of Section 13160 of the Water Code is identical in both.
TECHNICAL

The document was reformatted from a formal enrolled bill layout (with signature blocks, page numbers, and official seals) to a web page rendering that includes site navigation elements such as search bars, menu links, and bill history panels. No changes were made to the operative statutory text.
