Unleaded Avgas: FAA Approves Fleet, EPA Preps Regs
The FAA authorized all piston aircraft to use unleaded avgas, while the EPA is taking steps to phase out lead in fuels for aircraft with piston engines.

On Friday, one day after the FAA issued a draft policy statement on authorizing use of unleaded avgas for all piston-engine airplanes and helicopters, the Environmental Protection Agency (EPA) published a “proposed determination” that lead emissions from these aircraft using 100LL “cause or contribute to lead air pollution which may reasonably be anticipated to endanger public health and welfare.”
