AISI Statement On D.C. Circuit Decision On Particulate Matter Standard

Washington, D.C. – American Iron and Steel Institute (AISI) President and CEO Kevin Dempsey provided the following statement regarding the U.S. Court of Appeals for the D.C. Circuit denial of EPA’s motion to revoke the National Ambient Air Quality Standards for Particulate Matter (PM2.5 NAAQS):

“AISI strongly supports the current administration’s efforts to reconsider the PM2.5 NAAQS rule. If it remains in place, this standard would put much of the United States in nonattainment for PM2.5, regardless of the fact that the majority of PM2.5 emissions come from natural causes and non-industrial sources. Today’s court decision was a setback to EPA’s goal to establish a reasonable PM2.5 standard and avert the negative impacts of the current rule on the American steel industry’s international competitiveness. The American steel industry looks forward to continuing to work with the administration to ensure the implementation of reasonable regulations based on sound science.”

AISI submitted comments to EPA on the proposed rule last spring, which can be found here.
