AB 362California Assembly·2025-2026 Regular Session
Water policy: California tribal communities.
Summary
(1) The Porter-Cologne Water Quality Control Act establishes a statewide program for the control of the quality of all the waters in the state and makes certain legislative findings and declarations. Existing law defines the term "beneficial uses" for the purposes of water quality as certain waters of the state that may be protected against quality degradation, to include, among others, domestic, municipal, agricultural, and industrial supplies. This bill would add findings and declarations related to California tribal communities, as defined, and the importance of protecting tribal water use. The bill would add tribal water uses as waters of the state that may be protected against quality degradation for purposes of the defined term "beneficial uses." The bill would require any project or regulatory program subject to approval by the State Water Quality Control Board or a regional water quality control board, within a specified environmental review, and in any findings and declarations presented for state board or a regional board approval, to describe, with both quantitative and qualitative information, how the project or regulatory program will impact tribal water uses, and would require, on or before December 1, 2026, and every 2 years thereafter, the state board to publish a report on implementation of this provision on its internet website. (2) Existing law requires the state board to consult with and carefully evaluate the recommendations of concerned federal, state, and local agencies during the process of formulating or revising state policy for water quality control. This bill would additionally require the state board to consult and carefully evaluate the recommendations of concerned California tribal communities. (3) Existing law requires the state board to formulate and adopt state policy for water quality control. Existing law requires each regional board to formulate and adopt water quality control plans for all areas within the region and prohibits a water quality control plan, or a revision of the plan, adopted by a regional board from becoming effective unless it is approved by the state board. Existing law authorizes the state board to adopt certain water quality control plans. Existing law requires a regional board to establish water quality objectives in water quality control plans that in its judgment will ensure reasonable protection of beneficial uses and the prevention of nuisance and requires each regional board to consider specified factors in establishing water quality objectives. This bill would require, on or before January 1, 2027, the state board to propose, and solicit tribal consultation and public comment on, water quality standards to achieve reasonable protection of tribal water uses into the water quality control plan for the San Francisco Bay and Sacramento-San Joaquin Delta watershed. This bill would add consultations with California tribal communities and environmental justice considerations as factors for a regional board to consider in establishing water quality control objectives. The bill would exempt adoption of tribal water uses within water quality control plans from the California Environmental Quality Act, and would require, upon the next triennial review of a water quality control plan after January 1, 2026, each regional board to define tribal beneficial uses in its water quality control plan and, where applicable, adopt water quality standards to achieve reasonable protection of tribal water uses into water quality control plans. (4) Existing law requires the California Environmental Protection Agency and the Natural Resources Agency, on or before December 1, 2007, to enter into a memorandum of understanding for the purposes of establishing the California Water Quality Monitoring Council, which the state board is required to administer. Existing law requires the monitoring council to review existing water quality monitoring, assessment, and reporting efforts and to recommend specific actions and funding needs necessary to coordinate and enhance those efforts. Existing law requires the memorandum of understanding to describe the means by which the monitoring council shall formulate recommendations to reduce redundancies, inefficiencies, and inadequacies in existing water quality monitoring and data management programs and to ensure that water quality improvement projects financed by the state provide specific information necessary to track project effectiveness with regard to achieving clean water and healthy ecosystems. This bill would require, on or before December 1, 2026, the California Environmental Protection Agency and the Natural Resources Agency to amend the memorandum of understanding to incorporate participation from California tribal communities in the actions of the monitoring council, and would describe these potential methods of participation. The bill would require the memorandum of understating to include recommendations on how to achieve and maintain tribal water uses through state board and regional board regulatory actions and other programs, as specified. (5) Existing constitutional provisions require that a statute that limits the right of access to the meetings of public bodies or the writings of public officials and agencies be adopted with findings demonstrating the interest protected by the limitation and the need for protecting that interest. This bill would make legislative findings to that effect.
The April 21 amendment makes four substantive changes: it removes the definition of 'tribal water uses' from the Water Code (including a confidential disclosure provision and language making it an exclusive definition), corrects a drafting error in Section 13170.4 by removing a stray word, eliminates a hard January 1, 2029 deadline for regional boards to define tribal beneficial uses (keeping only the triennial review trigger), and adds a new tribal sovereignty provision stating that participation in water quality protection efforts is voluntary and does not subject tribes to state law in other matters.
Scope change
The removal of the 'tribal water uses' definition from Section 13050 narrows the bill's definitional framework, while the new sovereignty provision in Section 13243.5(c) broadens protections for tribal autonomy. The elimination of the 2029 deadline makes the timeline for regional board action less certain.
DEFINITION
The definition of 'tribal water uses' in Section 13050(t) was removed entirely, including language allowing tribes to confidentially disclose their water uses to the state board under Government Code Section 65352.4, and language stating this definition would be exclusive and replace all previously adopted agency definitions (such as 'tribal traditional cultural uses' and 'tribal subsistence uses').
TECHNICAL
Section 13170.4 was corrected to remove the word 'incorporate' that appeared before 'propose,' fixing a drafting error where both verbs were present in the prior version.
TIMELINE
Section 13243.5(b) removed the hard deadline of January 1, 2029 for regional boards to define tribal beneficial uses and adopt water quality standards. The obligation now triggers only upon the next triennial review of a water quality control plan after January 1, 2026, which could occur later depending on each region's review schedule.
SCOPE
New Section 13243.5(c) establishes that any participation by a California tribal community in efforts to protect tribal uses against quality degradation (through consultation, memorandum of understanding, or comanagement arrangement) is deemed voluntary and does not subject the participating tribe to state law in other matters not authorized by federal law.

MINOR
The changes between these two versions are primarily formatting and presentation differences rather than substantive policy changes. The bill text content (all sections amending or adding to the Water Code) appears identical between versions. The old version uses a traditional legislative document format with page numbers, line numbers, and formal layout, while the new version is a web-based rendering that adds navigation elements and removes the formal document structure.
TECHNICAL
The bill text was reformatted from a traditional legislative document layout (with page numbers like '97', sequential line numbers, and centered headers) into a web-based presentation format with navigation links, search tools, and standard web page elements.
Web navigation and interface elements were added, including quick search fields, bill information links, version comparison options, tracking features, and sharing tools.
The amended version of AB 362 softens two key implementation requirements related to tribal water use protections in water quality control plans. For the San Francisco Bay-Delta watershed, the state board is now required to propose standards and solicit tribal consultation and public comment rather than directly incorporating them. For all regional boards, the deadline for adopting tribal water use standards was changed from a fixed date of January 1, 2029 to the next triennial review after January 1, 2026, with an added preliminary step of first defining tribal beneficial uses.
REQUIREMENT
Section 13170.4: The state board's obligation for the San Francisco Bay and Sacramento-San Joaquin Delta watershed was changed from directly incorporating water quality standards to achieve reasonable protection of tribal water uses by January 1, 2027, to proposing such standards and soliciting tribal consultation and public comment on them by that date. This adds a deliberative process step before standards are finalized.
Section 13243.5: A new preliminary requirement was added that each regional board must first define tribal beneficial uses in its water quality control plan before adopting water quality standards, and standards adoption is now conditional on being 'where applicable.'
TIMELINE
Section 13243.5: The deadline for regional boards to adopt water quality standards protecting tribal water uses was changed from a fixed date of January 1, 2029, to the next triennial review of a water quality control plan after January 1, 2026. This ties the action to the existing regulatory review cycle rather than imposing a standalone deadline.
TECHNICAL
Various formatting and drafting clean-up throughout the bill, including removal of redundant 'which that' constructions, capitalization changes (e.g., 'Internet' to 'internet'), page number adjustments, and reformatting of the legislative counsel's digest to reflect amended language.
