The Marron Institute's Air Quality Program, led by Kevin Cromar, has been actively involved in the EPA's ongoing review of federal air quality standards for particulate matter and ozone. Dr. Cromar submitted comments on the integrated science assessment and policy assessment documents for both pollutants. These comments included research findings from the Air Quality Program showing that changing the level and form of the standard together has the potential to provide improved public health protection independent of changes to the stringency of federal air quality standards. Dr. Cromar presented this research at an invited talk for the Association of Air Pollution Control Agencies (AAPCA) in January. This research on the form of the standard was also cited and included in comments from the Clean Air Scientific Advisory Committee (CASAC) to the EPA as part of their review of the ozone policy assessment document.
