Three leading advocacy groups filed a petition today asking the U.S. Environmental Protection Agency to take action to address harms caused by lead emissions generated by the continued use of leaded aviation gasoline (avgas). Lead is a dangerous neurotoxin that destroys nerve tissue and causes a variety of health and neurological problems, particularly in children. Accordingly, EPA required a phase-out of lead in automobile fuel almost 20 years ago. But despite the fact that avgas-fueled aircraft are the single largest source of lead air emissions in the country, it has refused to impose any limits on this dangerous pollution source. Friends of the Earth, Physicians for Social Responsibility, and Oregon Aviation Watch have called on EPA to take the first step needed to begin to regulate lead emissions from aircraft.

“It is astonishing that, given EPA’s understanding of the serious health effects of lead exposure and its recognition of general aviation aircraft as the single largest source of lead emissions, this toxic pollution stream remains unregulated,” said Marcie Keever, legal director at Friends of the Earth. “We have been continually frustrated with EPA’s delay, and more than that, shocked that EPA allows the health of airport workers, pilots, passengers, and the communities surrounding these airports to remain unprotected from a known poison.”

Friends of the Earth, represented by public interest law firm Earthjustice and the Environmental Law and Justice Clinic at Golden Gate University School of Law, has been urging EPA to make an endangerment finding regarding lead emissions from general aviation aircraft since 2003. EPA denied an earlier petition from Friends of the Earth, stating that it was not ready to determine whether lead emissions from aircraft contributed to pollution that may endanger public health. Given new evidence about the effects of the toxic pollution source, Friends of the Earth—now joined by PSR and OAW—is asking EPA to reconsider its denial of the original petition and to issue an endangerment finding under the Clean Air Act for lead emissions from aircraft.

“An endangerment finding rests on meeting just two criteria: one that lead emissions from aircraft engines fueled by leaded avgas cause or contribute to air pollution, and two, that the air pollution from those lead emissions is reasonably anticipated to endanger the public health or welfare, “ said Earthjustice attorney Bridget Lee. “Both of these conditions have been met and, in fact, substantiated by EPA already. EPA’s contention that it must complete additional studies before making an endangerment finding is not supported by the law or the facts.”

“EPA’s delay in making an endangerment finding ignores clear science,” said Kathy Attar, Toxics Program Manager for Physicians for Social Responsibility. “The agency is contradicting its own admissions about the health risks of lead and the causal connection between lead emissions from general aviation aircraft and air pollution. And now, new scientific studies show that children suffer irreversible neurological and cognitive damage from exposure to even a small amount of lead.EPA knows that exposure to lead is not safe at any level. Every minute that EPA fails to act is causing permanent harm to children.”

In fact, according to EPA estimates, sixteen million people reside and three million children attend school in close proximity to the 20,000 airports where leaded avgas may be used.
“We are simply asking that EPA make an affirmative endangerment finding and establish regulations to protect millions from ill health caused by the known toxic effects of lead,” said Miki Barnes, President of Oregon Aviation Watch. “The facts are clear. There is no “safe” level of blood lead, or exposure to lead, especially for children. That’s why the law protects us from lead in paint and in our automobiles. In light of the evidence and the lives hanging in the balance, EPA must cease stalling and quickly move to regulate and ultimately eliminate the threat of lead poisoning from avgas as well.”
