Particulate Matter National Ambient Air Quality Standards Information Session Brianna Denk

On February 7, 2024, EPA finalized a more stringent NAAQS for fine particles (PM2.5). The previous PM2.5 annual standard set in 2012 was 12 µg/m³. The new, more stringent standard is now 9 µg/m³. The PM2.5 24-hour standard and the PM10 standard will remain unchanged. The DNR Air Management program will host an informational session on March 4, 2024 at 2:30 p.m. to provide an overview of the rule and how it impacts Wisconsin.

Publishing procedures

2011 Wisconsin Act 167 [exit DNR] went into effect on Aug. 1, 2012. This act requires the DNR to post hearing and permit notices on the department's website, in addition to newspapers. The date of posting on the DNR website now determines when the public comment periods end. If you have any questions about how this affects public comment opportunities, please contact Sheri Stach.
