Three Things EPA Administrator Andrew Wheeler Doesn’t Understand About Ambient Air Pollution Standards

, Research Director, Center for Science and Democracy

Last week, EPA Administrator Andrew Wheeler talked to Congress. Members had questions about his recent changes to the National Ambient Air Quality Standards updates for particulate matter and ozone. Wheeler’s comments last week and earlier make clear that he either doesn’t understand or isn’t being honest about how the EPA is proceeding as it sets health-protective air pollution standards. Here’s the reality around three points that Administrator Wheeler isn’t clear on.

Taking Science Out of Air Pollution Protections

, Research Director, Center for Science and Democracy

You and I enjoy cleaner air thanks to air pollution standards based on science. But now that could change. Last week, science advisors to the US Environmental Protection Agency (EPA) drafted a letter criticizing the agency’s use of science to set ambient air pollutant standards. This is the latest development in the EPA’s process to update the health protective standards for particulate matter and ozone—the two air pollutants most responsible for early death and sickness in this country.

On Thursday, November 29, the EPA’s Clean Air Scientific Advisory Committee (CASAC) will meet (via phone) for the first time since the recent upheaval in its membership. The agenda? To discuss the Integrated Review Plan for updating the ozone standard. And recently ousted scientists have something to say about it.
