Key Takeaways:

California's State Assembly and Senate approved S.B. 1193, a bill to ban leaded aviation gasoline statewide by the end of 2030, which is currently awaiting the Governor's signature.
This state measure is noted as aligning with a provision in the recently enacted federal FAA reauthorization bill from May 2024.
The federal FAA reauthorization generally prohibits U.S. airport operators from restricting 100LL until at least January 1, 2031, specifically exempting Santa Clara County, California, from this prohibition.

In late August, the California State Assembly and State senate both approved a measure that would ban leaded aviation gasoline throughout the state at the end of 2030. The bill, S.B. 1193, is now on Governor Gavin Newsom’s desk for signature. At this writing, he is expected to sign the bill into state law.

The bill’s passage ratchets up the rhetoric surrounding leaded aviation gasoline but really only recognizes language in the recently enacted five-year FAA reauthorization measure, which was signed into law by President Biden in May 2024. That measure includes a provision requiring U.S. airport operators to not restrict or prohibit 100LL until at least January 1, 2031 (except in Santa Clara County, California) if 100LL was available on the airport at any time in 2022.
