ACC appreciates the opportunity to submit the attached comments on U.S. Environmental Protection Agency's proposed "Reconsideration of the National Ambient Air Quality Standards for Particulate Matter." ACC member companies operate facilities throughout the country that are subject to emission limits under PM standards and as such, our members have a significant interest in any potential revision to existing NAAQS for PM.

Abstract

Based on EPA’s reconsideration of the air quality criteria and the NAAQS for particulate matter (PM), the EPA proposes to revise the primary annual PM2.5 standard by lowering the level. The Agency proposes to retain the current primary 24-hour PM2.5 standard and the primary 24-hour PM10 standard. The Agency also proposes not to change the secondary 24-hour PM2.5 standard, secondary annual PM2.5 standard, and secondary 24-hour PM10 standard at this time. The EPA also proposes revisions to other key aspects related to the PM NAAQS, including revisions to the Air Quality Index and monitoring requirements for PM NAAQS.
