Scientists to EPA: Stop Sidelining Science in the Air Pollution Standard Update for Particulate Matter

, Research Director, Center for Science and Democracy

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.

In the latest of several moves targeting EPA air pollution protections, the Trump administration appears to have cut scientists out of a process for reviewing particulate pollution standards.  The move breaks with a longstanding process for how the agency gets independent scientific review into its decisionmaking on air pollution protections. Without such expertise involved, EPA won’t have the best available scientific input to keep people safe from air pollution, as the law requires.
