Key Takeaways:

California's S.B. 1193, recently approved by its legislature and awaiting the Governor's signature, will ban leaded aviation gasoline (100LL) statewide by the end of 2030.
This state initiative follows a federal FAA reauthorization measure signed in May 2024.
The federal law generally prohibits U.S. airports from restricting 100LL until January 1, 2031, with Santa Clara County, California, being a notable exception.

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.
