From Flying magazine…
“The aviation community was expecting the announcement and points to progress on unleaded fuel in the market.
On Friday, the Environmental Protection Agency (EPA) released its proposed finding on leaded aviation fuel, triggering a response from the consortium of general aviation associations that have been working on the removal of lead from avgas with the FAA and industry partners. Under the EAGLE (Eliminate Aviation Gasoline Lead Emissions) initiative, the collective has demonstrated in recent months its commitment to sunsetting 100LL in a safe, deliberate manner.
The Proposed Endangerment Finding for Lead Emissions from Aircraft Engines that Operate on Leaded Fuel does not call for any immediate ban on avgas containing lead. It’s simply the initial step required for the agency to exercise its authority to “address this source of lead pollution,” which is well known to the GA industry.”
