EPA Administrator Michael Regan Responds to Questions about Leaded Aviation Fuel

October 6, 2023

Congresswomen Zoe Lofgren (D-CA) and Suzanne Bonamici (D-OR) Urge EPA to Address Leaded Aviation Fuel Pollution

"We need to do something soon and aggressive about this health problem." -- Rep. Zoe Lofgren

EPA Administrator Michael Regan testified at a 9/27/2023 hearing before the U.S. Congress House Science and Technology Committee. Concerns about the health impacts of leaded aviation fuel were discussed.

A Youtube video of the committee hearing is available here. The session begins around the 12:30 minute mark. Administrator Regan also submitted written testimony.

In her opening comments Rep. Zoe Lofgren (D-CA), the Ranking Member of the committee spoke to the issue of leaded aviation fuel. (Begins at 21:05 mark in the video)

"I also want to raise the issue of the last leaded fuel in transportation, and that is leaded fuel in general aviation airlines. We have a situation where children are being poisoned by the lead in these fuels. We have a study out of my own county showing that the airborne particles from emissions in small planes have actually elevated the lead in the blood level of children near that airport to rival Flint, Michigan. We need to do something soon and aggressive about this health problem and I’m hoping you can talk further about that as this hearing goes on."

This issue was addressed in greater detail later in the hearing. Below is the dialogue that transpired between Rep. Lofgren and Administrator Regan on this issue. (Begins at the 35:00 mark in the video)


Rep. Lofgren: Mr Chairman, Administrator Reagan, I want to ask you a question first about the subject I referenced in my opening statement and it's something I've been dealing with for quite some time. Leaded fuels are the primary fuel for piston engine aircraft -- I mean jets don't use, commercial airlines don't use leaded fuel. It's just the piston engine small aircraft which comprise really the bulk of the general aviation sector.

Now the Centers for Disease Control and Prevention CDC has concluded, based on scientific studies, that there is no known safe level of lead in the blood. What this means is that residents near general aviation airports live with lead exposure in the air and ground every day. Now as I mentioned there is a small airport in the district I represent, Reid-Hillview Airport. The county of Santa Clara commissioned a scientific study and found that the blood levels of children in the neighborhoods surrounding the airport had lead levels that were rivaling that in Flint, Michigan, and so it's very important that we get the lead out of this last part of transportation and protect the children of this country.

Congress instructed the FAA to come up with an alternative to leaded avgas, but they haven't been able to get the job done. More recently various groups have petitioned the EPA to finalize their endangerment finding related to leaded avgas. Now I'm hopeful that the finding will force the FAA and industry to come up with a plan to stop poisoning children with leaded fuels. Can you provide us with an update as to where this effort stands?

Administrator Regan: Well, Congresswoman, first of all I would agree with you that there is absolutely no acceptable level of lead for any of us, but especially our children. So EPA has been very active in this area, working very hard, following the science, following the process for a lead endangerment finding in this area. We're making significant progress and we believe that we'll have the endangerment finding wrapped up, I believe this fall. So that process is moving along in a very scientific and orderly way.

Congresswoman Lofgren: So we're in the fall. We could expect this quite soon, yes?

Administrator Regan: Yes, it will be done this fall, maybe late fall, but this fall. And I don't want to prejudge or predetermine the outcome, but what I want to tell you is we've been very methodical and disciplined on making this determination.

Congresswoman Lofgren: Thank you very much.


Congresswoman Suzanne Bonamici (D-OR) also commented on this issue. (Begins at 44:14 mark in video).


Rep. Bonamici: I want to start by aligning myself with representative Ranking Member Lofgren. As a representative for Hillsboro Oregon Airport, I want to emphasize again the importance of addressing lead pollution. Mr. Administrator, protecting public health and the environment, which is the EPA mission, requires strengthening, not cutting programs that are proven to work. And thank you, Administrator, for your commitment that the work of the EPA will be informed by rigorous and quality science.


Congresswoman Bonamici has scheduled a Town Hall meeting for November 9, 2023, at 6:00 PM in Hillsboro at the Evergreen Middle School. Information about her Town Hall meeting schedule is available here.
