Q&A on the future of avgas

Question: Since total avgas consumption is miniscule compared to fuel consumed by autos, trucks, and lawn mowers, why is the Environmental Protection Agency (EPA) even bothering general aviation with 100LL lead emissions?

Answer: Since the 1971 passage of the Clean Air Act, the EPA reasonably viewed the impact of 100LL on the air quality in the United States as de minimis. Avgas represents one third of 1 percent of all gasoline sales in the United States. However, the EPA’s “hand was forced” by a 2006 petition brought by the environmental group Friends of the Earth to review the lead emissions from 100LL in light of the 1971 Clean Air Act.
