Yesterday the EPA Clean Air Scientific Advisory Committee (CASAC) published a letter to Administrator Andrew Wheeler and acknowledged the group has inadequate expertise to conduct an essential review of the health impacts of particulate matter and ozone. We are now in uncharted territory and the EPA is in a tough position. Here are some key highlights from the letter and their implications. Read more >

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.

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.

Scientists to EPA: Stop Sidelining Science in the Air Pollution Standard Update for Particulate Matter
December 10, 2018 11:07 PM EDT
More than 200 air quality and public health experts have penned a letter expressing concern about the limited scientific input into an air pollutant standard update. The 206 scientists are deeply troubled by recent actions of the EPA on its update to the health-based standard for particulate matter, a pollutant comprised of tiny solid particles that has been linked to respiratory and cardiovascular effects and early death.
