CA SB318

Establishes statewide definitions for "best available control technology" (BACT) and "best available retrofit control technology" (BARCT) for air pollution control, requiring consideration of alternative technologies, process modifications, fuel selection, and pollution prevention measures

Requires air districts to submit proposed Title V permits to the State Air Resources Board executive officer for review, who must object within 45 days if the permit doesn't comply with federal Clean Air Act or state law; districts cannot finalize objected permits without addressing concerns

Mandates Title V permit renewal applicants submit technical feasibility analyses when equipment or control apparatus is 20+ years old and hasn't been reviewed under this section in 15 years (or 10 years for facilities in overburdened communities)

Requires the State Air Resources Board to update precertification criteria for equipment and processes at least every 8 years, and authorizes a voluntary program for temporary staff exchanges between the state board and air districts

Directs the State Air Resources Board to periodically issue BACT and BARCT determinations for source categories, prioritizing sources affecting disadvantaged communities, and allows public petitions requesting such determinations with required 60-day response times
