CA AB839

Authorizes the Governor to certify up to 3 sustainable aviation fuel (SAF) projects as infrastructure projects eligible for expedited CEQA judicial review, requiring legal challenges to be resolved within 270 days when feasible

Defines eligible SAF projects as new construction, conversion, or expansion of facilities that manufacture, process, store, distribute, or transport sustainable aviation fuel or its feedstocks, provided they do not use fossil fuels in production

Requires SAF projects that convert existing air pollution sources to demonstrate reduced emissions compared to baseline conditions, while new SAF projects must not cause significant air pollution effects as determined by the local air district

Mandates that certified SAF projects result in no net additional greenhouse gas emissions, with applicants required to pay court costs for any legal challenges and costs for preparing concurrent environmental records

Expands duties of lead agencies for infrastructure projects, creating a state-mandated local program, though no reimbursement is required because local agencies can levy fees to cover costs
