SB 86: California Alternative Energy and Advanced Transportation Financing Authority Act: sales and use tax exclusion.

Existing sales and use tax laws impose taxes on retailers measured by the gross receipts from the sale of tangible personal property sold at retail in this state, or on the storage, use, or other consumption in this state of tangible personal property purchased from a retailer for storage, use, or other consumption in this state. The California Alternative Energy and Advanced Transportation Financing Authority Act establishes the California Alternative Energy and Advanced Transportation Financing Authority. The act authorizes, until January 1, 2026, the authority to provide financial assistance to a participating party by authorizing exclusions from sales and use tax for certain projects, including those that promote California-based manufacturing, California-based jobs, advanced manufacturing, the reduction of greenhouse gases, or a reduction in air and water pollution or energy consumption. The Sales and Use Tax Law, for the purposes of the taxes imposed pursuant to that law, until January 1, 2026, excludes the lease or transfer of title of tangible personal property constituting one of those projects to any contractor for use in the performance of a construction contract for a participating party that will use that property as an integral part of the approved project. This bill would extend to January 1, 2028, the authorization to provide financial assistance in the form of a sales and use tax exclusion for projects approved by the authority. The bill would add electrical generation facilities using nuclear fusion technology to the types of projects qualifying for this sales and use tax exclusion. The bill would, on and after January 1, 2026, for an applicant that, together with its parent corporation and subsidiaries, employs 500 or more employees, prohibit the authority from approving a project unless the applicant certifies that the applicant and its subcontractors will comply with certain labor requirements. The bill would make other conforming changes. This bill would take effect immediately as a tax levy.

SB 594: Short-Term Rental Facilitator Act of 2026.

Existing law, the Short-Term Rental Facilitator Act of 2025, authorizes a local agency to enact an ordinance to require a short-term rental facilitator, as defined, to report, in the form and manner prescribed by the local agency, the physical address of each short-term rental, as defined, during the reporting period. Existing law requires a short-term rental facilitator, in a jurisdiction that has adopted an ordinance, to include in the listing of a short-term rental any applicable local license number associated with the short-term rental and any transient occupancy tax certification issued by a local agency. Existing law authorizes a local agency to, if the short-term rental facilitator is responsible for collecting and remitting the transient occupancy tax to the local agency pursuant to a local ordinance or collection agreement, conduct an audit or otherwise examine the records of the short-term rental facilitator documenting the receipt of the transient occupancy tax due and payable to the local agency. This bill would enact the Short-Term Rental Facilitator Act of 2026. The bill would authorize an Indian tribe, as defined, to exercise the same powers a local agency has under the Short-Term Rental Facilitator Act of 2025. The bill would provide that an "ordinance" under the act refers to a tribal law of an Indian tribe imposing a transient occupancy tax.

SB 601: Water: waste discharge.

(1) Under existing law, the State Water Resources Control Board and the 9 California regional water quality control boards regulate water quality and prescribe waste discharge requirements in accordance with the Porter-Cologne Water Quality Control Act (act) and the National Pollutant Discharge Elimination System (NPDES) permit program. Under the act, the State Water Resources Control Board is authorized to adopt water quality control plans for waters for which quality standards are required by the federal Clean Water Act, as specified, and that in the event of a conflict, those plans supersede regional water quality control plans for the same waters. This bill would authorize the state board to adopt water quality control plans for nexus waters, which the bill would define as all waters of the state that are not also navigable, except as specified. The bill would require any water quality standard that was submitted to, and approved by, or is awaiting approval by, the United States Environmental Protection Agency or the state board that applied to nexus waters as of May 24, 2023, to remain in effect, as provided. The bill would require the state board and regional boards to include nexus waters in all federal Clean Water Act processes, including, but not limited to, the California Integrated Report and the establishment of total maximum daily loads, as specified. (2) Existing law requires a regional board, after any necessary hearing, to prescribe requirements as to the nature of any proposed discharge, existing discharge, or material change in an existing discharge, except discharges into a community sewer system, with relation to the conditions existing in the disposal area or receiving waters upon, or into which, the discharge is made or proposed and sets forth what the requirements are to include. This bill would require the above-described discharge requirements to, in the case of discharges from any point source to nexus waters, implement, at a minimum, the requirements of provisions implementing the Federal Water Pollution Control Act and acts amendatory thereof or supplementary thereto. (3) The act authorizes the imposition of civil penalties for violations of certain waste discharge requirements, including violation of a cease and desist order or a cleanup and abatement order, and requires that penalties imposed pursuant to these provisions be deposited into the Waste Discharge Permit Fund, to be expended by the state board, upon appropriation by the Legislature, for specified purposes related to water quality. For violations of certain other waste discharge requirements, the act imposes specified civil penalties, the proceeds of which are deposited into the continuously appropriated State Water Pollution Cleanup and Abatement Account. This bill would require, commencing January 1, 2026, and each calendar year thereafter, the state board's executive director to adjust civil monetary penalties, as specified, including the civil penalties for the above-described provisions. The bill would require moneys collected in accordance with these annual adjustments to be deposited into the Penalty Adjustment Account, that the bill would establish within the Waste Discharge Permit Fund, and upon appropriation by the Legislature, be expended by the state board for purposes of cleaning up and abating the effects of waste on waters of the state. (4) Existing law generally provides for enforcement and implementation of the act. This bill would authorize specified entities, including the Attorney General and the state board, to bring an action to enforce certain provisions related to nexus waters or waste discharge requirements for nexus waters, as provided. (5) The act provides various provisions related to waste discharge to ensure consistency with the requirements for state programs implementing the Federal Water Pollution Control Act and acts amendatory thereof or supplementary thereto. The act defines the terms "navigable waters," "administrator," "pollutants," "biological monitoring," "discharge," and "point sources" as having the same meanings as in the Federal Water Pollution Control Act. This bill would provide that "waste discharge requirements" include waste discharge requirements issued for discharges to nexus waters, and "discharge" includes any addition of a pollutant to a nexus water from any point source. The bill would provide that for purposes of compliance with the Federal Water Pollution Control Act, nexus waters shall be treated as though they are navigable waters and navigable waters of the United States. The bill would require waste discharge requirements adopted or amended for discharges to nexus waters to be adopted pursuant to and in accordance with the requirements of provisions implementing the Federal Water Pollution Control Act and acts amendatory thereof or supplementary thereto, as specified. (6) The act requires a person who discharges pollutants or proposes to discharge pollutants to the navigable waters of the United States within the jurisdiction of this state or a person who discharges dredged or fill material or proposes to discharge dredged or fill material into the navigable waters of the United States within the jurisdiction of this state to file a report of the discharge, except as specified. The act prohibits the discharge of pollutants or dredged or fill material or the operation of a publicly owned treatment works or other treatment works treating domestic sewage by any person, except as authorized by waste discharge requirements or dredged or fill material permits. This bill would require a person to file a report for discharges to nexus waters. The bill would apply the above-described prohibition to nexus waters.

AB 763: Timber harvesting: waste discharge requirements.

The Porter-Cologne Water Quality Control Act requires a California regional water quality control board to prescribe waste discharge requirements for the discharge of pollutants into state waters and authorizes the regional board to prescribe general waste discharge requirements for a category of discharges if the regional board finds or determines that certain criteria apply to the discharges in that category. This bill would require, for a regional board that has adopted general waste discharge requirements for timber harvesting, the regional board to approve, deny, or otherwise act on a request for coverage for timber harvesting operations performed consistent with an approved timber harvesting plan subject to those general waste discharge requirements.

SB 31: Water quality: recycled water.

(1) The Water Recycling Law generally provides for the use of recycled water. Existing law requires any person who, without regard to intent or negligence, causes or permits an unauthorized discharge of 50,000 gallons or more of recycled water in or on any waters of the state to immediately notify the appropriate regional water board. This bill would, for the purposes of the above provision, redefine "recycled water" and provide that water discharged from a decorative body of water during storm events is not to be considered an unauthorized discharge if recycled water was used to restore levels due to evaporation. (2) Existing law regulating the use of recycled water prohibits the use of prescribed potable water by state and local agencies for any nonpotable uses, including cemeteries, golf courses, parks, and highway landscaped areas if prescribed recycled water is available, and deems use of the recycled water in lieu of the potable water to constitute a reasonable beneficial use of that water. The bill would provide that incidental amounts of spray, mist, or runoff are to be permitted to enter outdoor eating areas of parks and open spaces when irrigated with disinfected tertiary treated recycled water that complies with a specified regulation regarding irrigation. (3) Existing law authorizes any public agency, including a state agency, city, county, city and county, district, or any other political subdivision of the state, to require the use of recycled water for irrigation of residential landscaping, as specified. The bill would provide that outdoor landscape irrigation of common areas that does not enter the boundaries of a residence is not to be considered a part of the same premises as an individual residence and is not to be considered a dual-plumbed system. The bill would require recycled water used for this purpose to comply with specified water quality and cost conditions. (4) Existing law authorizes any public agency, including a state agency, city, county, city and county, district, or any other political subdivision of the state, to require the use of recycled water for toilet and urinal flushing in structures, as specified. Existing law defines "structures" for the purposes of these provisions. This bill would include food handling and processing facilities as part of the definition of "structures." The bill would authorize the use of recycled water for toilet or urinal flushing or outdoor irrigation in and around food handling or processing facilities, commercial, institutional, and industrial buildings, and cafeterias, provided the recycled water does not enter the room where food handling or processing occurs, as specified.

AB 1373: Water quality: state certification.

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.

AB 497: San Francisco Bay/Sacramento-San Joaquin Delta Estuary Water Quality Control Plan: update: substitute environmental document: exemption.

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 establishes the State Water Resources Control Board to exercise the adjudicatory and regulatory functions of the state in the field of water resources. Pursuant to its authority, the board adopted the Water Quality Control Plan for the San Francisco Bay/Sacramento-San Joaquin Delta Estuary (Bay-Delta Plan) that, among other things, establishes objectives to protect the beneficial uses of the water and prevent nuisance within the waters specified in the Bay-Delta Plan. Existing law, the California Environmental Quality Act (CEQA) , requires a lead agency, as defined, to prepare, or cause to be prepared, and certify the completion of, an environmental impact report (EIR) on a project that it proposes to carry out or approve that may have a significant effect on the environment or to adopt a negative declaration if it finds that the project will not have that effect. CEQA also requires a lead agency to prepare a mitigated negative declaration for a project that may have a significant effect on the environment if revisions in the project would avoid or mitigate that effect and there is no substantial evidence that the project, as revised, would have a significant effect on the environment. CEQA, except as provided, when a regulatory program of a state agency requires a plan or other written documentation containing environmental information, authorizes that plan or other information to be submitted in lieu of the EIR if the Secretary of the Natural Resources Agency has certified that regulatory program, as specified. This bill would require the board to adopt an update to the Bay-Delta Plan that addresses the Sacramento River and its tributaries, Sacramento-San Joaquin Delta (Delta) eastside tributaries, and the Delta no later than August 31, 2026. The bill would exempt the board from the requirements to prepare, provide for review, transmit to state agencies, and include written or oral responses to comments on a specified draft substitute environmental document, as provided.

AB 1313: Water quality: permits.

Under existing law, the State Water Resources Control Board and the 9 California regional water quality control boards regulate water quality and prescribe waste discharge requirements in accordance with the federal national pollutant discharge elimination system (NPDES) permit program established by the federal Clean Water Act and the Porter-Cologne Water Quality Control Act. Existing law requires each regional board to formulate and adopt water quality control plans for all areas within the region, as provided. The bill would require the state board, after making the necessary residual designation authority findings, to establish a statewide commercial, industrial, and institutional NPDES order for properties with 5 acres or more of impervious surface, as provided. The bill would require the state board to publish a draft order of the statewide order for public comment on or before December 31, 2028, or 18 months after the reissuance of a specified statewide permit, as specified. The bill would require the state board to contemporaneously establish rules for offsite compliance agreements to issue with the publication of the draft statewide order for public comment that details the necessary components of an agreement between commercial, industrial, and institutional permittees and local municipalities for achieving offsite stormwater capture and use within the adopted final statewide commercial, industrial, and institutional NPDES order. The bill would require the NPDES order to include multiple compliance options for discharges to select and comply with to be deemed in compliance with applicable water quality based effluent limitations, including, but not limited to, compliance options incentivizing green infrastructure onsite or offsite stormwater capture and use.

AB 362: Water policy: California tribal communities.

(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.
