U.S. EPA Proposes Changing PM 2.5 Standard

On Jan. 6, the U.S. EPA announced it would reconsider National Ambient Air Quality Standards for particulate matter, also known as the PM 2.5 standard.

The National Association of Manufacturers criticized the announcement, with NAM President and CEO Jay Timmons saying U.S. air quality has improved by more than 30% during the past 20 years, while production and energy consumption have grown. Changing the standard will only further weaken an already slowing economy, Timmons said. 1/10/2023
