Lead Emissions from Piston-Engine Aircraft Using Leaded Aviation Gasoline

a.k.a. Lead in Aviation Gasoline

RIN: 2060-AP79 (What's this?)

Docket No.: EPA-HQ-OAR-2007-0294 (What's this?)

Current Phase: Pre-Proposal (What's this?)

The purpose of this action is to further respond to a petition submitted by Friends of the Earth (FOE) in 2006. In the petition, FOE requests that the EPA find that lead emissions from general aviation aircraft may reasonably be anticipated to endanger public health and welfare and that the EPA propose emissions standards under the Clean Air Act for lead from general aviation aircraft.

Alternatively, FOE requests that the EPA commence a study and investigation of the health and environmental impacts of lead emissions from general aviation aircraft, if the EPA believes that insufficient information exists to make such a finding. In 2007 the EPA issued a Federal Register notice seeking comment on FOE's petition. The notice asked a series of questions seeking information on exposure to lead emissions from general aviation aircraft, lead emission rates from general aviation aircraft, unleaded aviation fuel options, and engine technology. The EPA has long-standing concerns regarding exposure to lead, particularly during childhood. The most recent lead National Ambient Air Quality Standards review, finalized in 2008, found that serious health effects occur at much lower levels of lead in blood than previously identified and did not identify a safe level of lead exposure. Emissions of lead from piston-engine aircraft using leaded aviation gasoline comprise over half of the national inventory of lead emitted to air. There are almost 20,000 airport facilities in the U.S. at which leaded aviation gasoline is used. This action described the lead inventory related to use of leaded aviation gasoline, air quality and exposure information, additional information the Agency is collecting related to the impact of lead emissions from piston-engine aircraft on air quality and requested comments on this information.

Potential Effects

Children's Health
This rule is likely to address an adverse impact on childhood lifestages, including prenatal (via exposure to women of childbearing age). The potential adverse impacts are expected to be due to exposure (i.e., children and/or women of childbearing age are more likely to be highly exposed than other lifestages).

Environmental Justice
This rulemaking involves a topic that is likely to be of particular interest to or have particular impact upon minority, low-income, tribal, and/or other vulnerable populations because:

  • This topic is likely to present an opportunity to address an existing disproportionate impact on vulnerable populations.
