EPN Comments on Draft Policy Assessment for Ozone

On December 16, 2019, EPN submitted comments on EPA’s draft Policy Assessment (PA) of the scientific basis for the National Ambient Air Quality Standards for ozone. The Clean Air Act requires EPA to set standards for common air pollutants that are harmful to public health and the environment, and periodically review the standards and the science on which they are based. EPN’s review found that the draft PA recommends no revision of the current secondary standard, contrary to the court’s decision in Murray Energy v. EPA, and does not analyze any alternative standards. As a result, the agency should prepare a draft PA that accounts for the court’s findings and resubmit that draft to the Clean Air Scientific Advisory Committee (CASAC)  for review.
