Clean Wisconsin calls on EPA to protect Wisconsinites from dangerous leaded aviation fuel

Small, recreational aircraft are the largest source of lead air pollution in Wisconsin. People living near airports that serve small planes are most at risk for exposure.

Clean Wisconsin is urging its members across the state to contact the Environmental Protection Agency (EPA) and tell the agency to take the first step toward regulating leaded aviation fuel.

In Wisconsin, 80% of lead air emissions come from aircraft, especially small recreational planes that still use leaded fuel. Wisconsinites living near airports that serve small planes are the most at risk for exposure to lead air pollution. The counties with the highest levels of aircraft lead emissions are Racine, Dane, Jefferson, Winnebago and Sauk. Individual airports reporting the most lead emissions are Wittman Regional, Fond Du Lac County, Sheboygan County Memorial, Burlington Municipal, and Watertown Municipal.

Clean Wisconsin Science Program Director Paul Mathewson says there’s a good reason the EPA began phasing out leaded gasoline for cars and trucks 50 years ago.

“There is no safe level of lead exposure,” Mathewson says. “Exposure to lead pollution is particularly dangerous for children, causing lifelong health effects. Childhood lead exposure impairs development of the nervous system leading to behavioral problems, learning disabilities, and reduced academic achievement.”

Mathewson points to Morey Field in the Town of Middleton, where there is growing concern among neighbors over lead emissions.

“Morey Field has more lead emissions than the much larger General Mitchell airport in Milwaukee. That’s because commercial jets don’t use leaded fuel, but most small planes still do,” he says. “The Town of Middleton has found elevated levels of lead in the air near Morey Field, as well as evidence that lead from the airplane fuel is getting into drinking water supplies”.

[inaarticlead ad=”UM-In-Article-2″}Now, the EPA is poised to take the first step to regulate aircraft lead emissions.

The EPA recently proposed an “endangerment finding” for lead emissions from aircraft which concludes that these emissions are a danger to public health. Once the finding is adopted, the EPA can propose regulatory standards for lead emissions from aircraft engines.

Clean Wisconsin is urging people to submit comments to the EPA in support of an endangerment finding. Comments will be accepted through January 17th.
