National Ambient Air Quality Standards (NAAQS)

  • 11/12/2019

    The Clean Air Act requires the Environmental Protection Agency to set National Ambient Air Quality Standards (NAAQS) at a level requisite to protect public health with an adequate margin of safety, and to periodically review those standards to keep pace with science. CATF joined with EDF and NRDC to submit comments expressing concern about the NAAQS review process and urging EPA to revise the standards for particulate matter to provide the protection required by law.
