The general aviation community is committed to removing lead from aviation gasoline by the end of this decade but the Environmental Protection Agency (EPA) must ensure that any endangerment finding and subsequent ban on its use enables a safe and orderly transition to unleaded avgas, a group of seven industry organizations said. In joint comments on the EPA’s proposed endangerment finding, the groups further reminded the EPA that the FAA must be involved in regulation requiring the end of leaded avgas.

In October, the EPA issued a proposal to find that lead emissions from aircraft using 100LL “cause or contribute to lead air pollution which may reasonably be anticipated to endanger public health and welfare." Plans call for the EPA to issue any final endangerment finding this year, setting in motion follow-on actions that would ultimately end the use of lead in avgas.
