AFS Calls on EPA to Withdraw Proposed Reconsideration of PM2.5 NAAQS 

The American Foundry Society is pushing back on a proposal from EPA to change a National Ambient Air Quality Standard (NAAQS) that was previously updated in 2020.

In comments filed with the agency on March 29, AFS said EPA's plan to lower the PM2.5 emissions threshold is premature and would lead to confusing and conflicting requirements for manufacturers. AFS noted the plan would punish the many metalcasters who have already invested in new control technology to cut their emissions to the 2020 standard. Nearly half of the counties in the U.S. could be impacted by the new standard. 

The NAAQS proposal will be one of four emerging topics highlighted during “Policy Issues Affecting Metalcasters,” an AFS Members-Only Webinar at 1 p.m. CT on April 6. Presenters Jeff Hannapel and Stephanie Salmon will explore the implications of these top issues impacting metalcasters and answer your questions. Registration is free for members or $250 for non-members.
