California Bill Would Phase Out 100LL Starting In 2026

Gemini Sparkle

Key Takeaways:

  • California Democratic senators have introduced SB1193, a bill to implement a phased ban on the sale of 100LL aviation fuel, starting at specific busy airports in 2026 and becoming a statewide ban by January 1, 2030.
  • The legislation prioritizes airports near "disadvantaged communities" or large cities, driven by health and community impact concerns, and aims for California to lead environmental action.
  • This proposed ban would accelerate the transition from 100LL four years ahead of the FAA's nationwide timeline, potentially conflicting with federal jurisdiction, and is opposed by aviation organizations like the EAA.

A pair of California Democratic senators have introduced a bill that would start banning the sale of 100LL at some of its busiest GA airports starting Jan. 1, 2026. The bill, introduced by Sen. Caroline Menjivar and Sen. Henry Stern at a streaming event at Whiteman Airport in Pacoima, in the San Fernando Valley, two weeks ago, would end sales of 100LL at airports next to a “disadvantaged community” (California defines those areas in its Health and Safety Code) or next to a city with more than 700,000 people. Those definitions would cover much of the Los Angeles basin and areas of the San Francisco Bay area. In 2028, the ban would apply to airports next to an urban growth boundary (a development boundary that prevents urban sprawl). On Jan. 1, 2030, 100LL would be banned statewide.

If the law is enacted (it has already been referred to the State Senate’s transportation and judiciary committees) it would start the ban of 100LL four years ahead of the FAA’s timeline, which is aiming for 2030. It would also likely conflict with federal jurisdiction over airport management, but Menjivar said the health and community impacts demand immediate action. She said California has always been at the forefront of environmental action and she said after her state enacts the ban, others will follow. “California needs to lead from the front,” she said. EAA reported last week that it was aware of the new bill and was planning to fight it.
