ABSTRACT

Ozone and Particulate Matter Air Standards: EPA Review [Updated December 23, 2020]   [open pdf - 470KB]

From the Document: "The Clean Air Act (CAA) requires the U.S. Environmental Protection Agency (EPA) to review standards for national ambient air quality every five years. In 2018, EPA announced strategies to expedite the National Ambient Air Quality Standard (NAAQS) review while concurrently disbanding a pollutant-specific scientific review panel that has historically advised agency staff during their reviews. Although the CAA allows the EPA Administrator to specify the procedures for review of the NAAQS, past EPA reviews and revisions have garnered considerable congressional oversight. In December 2020, EPA completed the particulate matter (PM) NAAQS review and retained the standards. This In Focus discusses the recently completed PM NAAQS review and the ongoing ozone review."
