AB 839 updates the chapter’s definitions to add "sustainable aviation fuel projects" to the list of "infrastructure projects" that may be certified under Sections 21189.82 and 21189.83. The bill spells out what counts as a sustainable aviation fuel (SAF) project and imposes eligibility tests tied to emissions, feedstock and production processes, and existing air permits.
The measure also refines and sets technical thresholds for energy-related infrastructure—defining transmission projects that qualify, minimum sizes for energy storage, manufacturing capital thresholds, hydrogen project funding sources, and labor-designations for transportation and water projects. Those definitional choices will determine which facilities can access the chapter’s streamlined CEQA pathway and which remain subject to standard CEQA procedures, with direct consequences for developers, air districts, utilities, and local communities.
At a Glance
What It Does
Amends the chapter’s definitions so that a sustainable aviation fuel project is an "infrastructure project" eligible for certification under Sections 21189.82 and 21189.83, subject to specified technical and air‑quality requirements. It also clarifies eligible energy, transmission, hydrogen, manufacturing, transportation, semiconductor, and water projects and sets size and funding thresholds.
Who It Affects
Developers of SAF facilities and their supply chains, air districts tasked with emissions determinations, grid operators and publicly owned utilities proposing transmission projects, manufacturers seeking qualifying capital thresholds, and contractors on transportation and water public‑works projects.
Why It Matters
By defining which projects qualify, the bill governs who can use the chapter’s expedited CEQA certification and judicial‑review procedures. The eligibility criteria—emissions tests, non‑fossil production requirements, and investment thresholds—will steer private capital and influence where projects are sited and how they are designed.

What This Bill Actually Does
The bill does not rewrite CEQA’s substance; it rewrites who can reach an accelerated permitting track under this chapter by adding SAF projects to the list of "infrastructure projects." To qualify, an SAF project must meet an existing statutory standard (Section 21183.5), certify that its production process does not use fossil fuels, and satisfy air‑district determinations about local pollutant effects or emission reductions when a project involves converting or replacing an existing major (Title V) source. In short: SAF projects can seek the chapter’s streamlined path, but only if they clear built‑in air‑quality gates.
Beyond SAF, the bill tightens technical definitions that determine eligibility for other energy projects. It sets a floor for new energy storage (20 megawatts with at least two‑hour discharge capability), limits qualifying pumped‑hydro to projects ≤500 megawatts funded by the state before 2023, and creates a manufacturing pathway for projects that commit at least $250 million in capital investment over five years for producing storage, wind, or solar components.
It also makes explicit that certain transmission projects identified by the ISO or local publicly owned utilities qualify when they specifically facilitate renewable or storage deliveries.The measure ties hydrogen project eligibility to non‑fossil feedstocks and enumerated funding sources (the state Hydrogen Program, a specified bond provision if approved by voters, or federal ARCHES awards). Transportation and water projects that qualify are designated public works subject to Labor Code Section 1720, which imports prevailing‑wage and other public‑works requirements.
The bill preserves Coastal Commission jurisdiction for transmission facilities located in the coastal zone and excludes through‑Delta conveyance design/construction from the water‑project definition.Taken together, these definitions are the gatekeeper: they don't guarantee approvals, but they determine whether a developer can ask for the faster certification and limited judicial‑review track that the chapter makes available. The criteria combine technical size thresholds, funding-source conditions, and local air‑district review—so project sponsors must design to those tests if they want the expedited path.
The Five Things You Need to Know
The bill expressly adds "sustainable aviation fuel project" to the statutory list of "infrastructure projects" eligible for certification under Sections 21189.82 and 21189.83.
An SAF project must (a) meet the requirements of Section 21183.5, (b) not use fossil fuels in its production process, and (c) either reduce emissions if converting a Title V source or cause no significant air pollutant effect if a new source, per the applicable air district.
The bill defines "sustainable aviation fuel" by reference to ASTM D7566 and California regulatory standards in Title 17, Subarticle 7.
Energy storage projects qualify only if they are 20 megawatts or larger and can discharge for at least two hours; pumped hydro qualifies only if ≤500 megawatts and was state‑appropriated before January 1, 2023.
Manufacturing projects qualify only if the applicant certifies at least $250 million in capital investment over five years for specified component or system manufacturing tied to renewables or storage.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Applicant and disadvantaged community definitions
Subsections (a) and (b) set who can be an "applicant" (public or private entities and successors) and define "disadvantaged community" by cross‑reference to existing CalEPA and General Code provisions. Those cross‑references matter because later eligibility rules and siting considerations often interact with disadvantaged‑community designations for mitigation, funding, or project prioritization.
Electrical transmission facility project — ISO and POUs
This subsection narrows qualifying transmission projects to those identified by the Independent System Operator in its annual plan or by a local publicly owned utility to meet an approved expansion need, and only when the project facilitates delivery of renewable, zero‑carbon, or stored energy. Practically, that links eligibility to formal planning documents, not ad hoc upgrades, and gives grid planners a de facto veto over which transmission lines can access the chapter’s expedited track.
Energy infrastructure — storage, manufacturing, and hydrogen gates
This block defines eligible energy projects: new renewable resources (excluding biomass combustion), storage systems of 20 MW+ with at least two hours of discharge, and a manufacturing route that requires a $250 million five‑year capital commitment for certain component production. It also allows hydrogen production facilities that use non‑fossil feedstocks and receive funding from enumerated programs. Each subpart imposes size, technology, or funding conditions that narrow the class of projects that can benefit from expedited CEQA treatment.
What counts as an 'infrastructure project' and semiconductor tie‑ins
Subsection (e) lists five categories (energy, semiconductor/microelectronic, sustainable aviation fuel, transportation, water) as "infrastructure projects" if certified under Sections 21189.82/83. Subsection (f) ties semiconductor eligibility to CHIPS Act award recipients and Section 21183.5 requirements, effectively linking federal funding decisions to state CEQA streamlining access.
Sustainable aviation fuel project and fuel definition
These clauses define the scope of SAF projects: construction, conversion, expansion, storage, distribution, transport, feedstocks, and electrochemical components all count. Qualifying tests require compliance with Section 21183.5, a prohibition on fossil fuels in the production process, and air‑district determinations about emissions reductions (for Title V conversions) or no significant pollutant effects (for new sources). Subsection (h) defines SAF by reference to ASTM D7566 and California’s Title 17 standards, anchoring the statutory term to established fuel specifications.
Transportation-related projects and labor rules
Transportation projects must advance specified Climate Action Plan goals (rail/transit, bike/ped, zero‑emission vehicle infrastructure, zero‑emission freight, climate risk assessment, compact infill, etc.) and cannot conflict with those goals. Crucially, transportation projects are explicitly public works under Labor Code Section 1720 and must comply with prevailing‑wage and other public‑works provisions, which affects project costs, procurement, and contractor qualification.
Water-related projects and exclusions
Water projects are narrowly defined: groundwater‑sustainability implementation, California Water Commission‑funded storage that minimizes diversion and prioritizes ecological discharge, recycled water development, contaminant/salt removal (not seawater desalination), and certain maintenance-only work. They are also public works under Section 1720. The clause explicitly excludes design/construction of through‑Delta conveyance facilities, removing a politically sensitive class of projects from the definition.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Large SAF developers that can certify non‑fossil production processes — they gain access to an expedited CEQA track if they meet the air‑district and Section 21183.5 conditions, shortening legal exposure and permitting timelines.
- Airlines and fuel purchasers seeking domestic SAF supply — greater regulatory clarity and a pathway for large, integrated facilities can attract investment that increases regional SAF availability.
- Renewable energy and storage manufacturers that meet the $250 million capital threshold — the definition creates a clear route for large manufacturing projects tied to storage, wind, or solar component production to qualify for streamlined review.
- Publicly owned utilities and grid planners — transmission projects explicitly identified in ISO planning or POU expansion needs can leverage the chapter’s processes to move projects that enable renewable and storage delivery.
Who Bears the Cost
- Local air districts — the bill delegates key judgments about whether an SAF project causes significant pollutant effects or reduces emissions for Title V conversions, increasing technical review and enforcement responsibility.
- Smaller developers and startups — the $250 million capital threshold and minimum sizing for storage (20 MW/2‑hour) favor large projects and may exclude smaller, potentially innovative facilities from the expedited pathway.
- Contractors and project owners on transportation and water projects — treating these projects as public works imports prevailing‑wage and compliance costs and changes procurement dynamics that raise project labor costs.
- State and regional permitting bodies — agencies that must implement certification under Sections 21189.82/83 and reconcile local concerns (coastal jurisdiction, community impacts) face additional workload and potential litigation over discretionary determinations.
Key Issues
The Core Tension
The bill prioritizes speed and certainty for large, climate‑aligned infrastructure by creating a tailored expedited pathway, but doing so requires delegating technical and environmental judgments to agencies and imposing size and funding gates that can leave local health impacts, equity, and smaller innovators disadvantaged—forcing a choice between rapid deployment and uniformly protective, locally accountable environmental review.
The bill’s core levers are technical thresholds and cross‑references to external standards or funding programs; those levers create several implementation questions. First, the phrase "does not use fossil fuels in its production process" is operationally ambiguous: does it cover only feedstocks, or also electricity and natural‑gas‑fired heat used on site or upstream in inputs?
Regulators will need measurement protocols and lifecycle accounting rules to make that determination administrable and defensible.
Second, the bill delegates air‑quality judgments to local air districts, which vary in technical capacity and policy posture. Two identical projects could receive different outcomes in different districts, producing uneven access to the expedited track and shifting siting incentives.
Third, the $250 million capital‑investment and energy‑storage size gates privilege scale; that concentrates benefits in larger, vertically integrated firms and may discourage distributed or modular solutions that could be lower cost or more locally resilient.
Finally, the statute preserves certain external jurisdictions (e.g., Coastal Commission) and ties eligibility to specific funding sources (CHIPS, ARCHES, state hydrogen funds). That linkage creates an administrative coupling: federal awards or bond approvals become de facto qualifiers for state CEQA streamlining.
The interplay between funding, technical definitions, and local air‑quality roles raises questions about predictability, equity, and how agencies will document compliance if challenged in court.
