EPA Getting Serious About Lead in Avgas?
The Environmental Protection Agency continues to go through administrative motions suggesting it's serious about removing lead from avgas. Earlier this month, the agency sent a draft endangerment finding to the White House as part of its proposed action to address a petition from Friends of the Earth claiming that lead in avgas represents a public health risk.
Before it can move forward, the EPA has to issue a finding under terms of the Clean Air Act that health risks actually exist. To reach that finding, the agency has ordered lead pollution studies around a number of U.S. airports. Friends of the Earth has asked EPA to ban lead from avgas "without delay," although the industry still has no ready high-octane substitute for 100LL.
