Taking Science Out of Air Quality—EPN’s Defense of Public Health and the Integrity of the CASAC

On October 10, 2018, with no opportunity for input, or reasonable explanation, EPA abandoned plans to reinstate the Ozone Review Panel (experts who aid in the assessment of the ground-level ozone limits) and disbanded the Particulate Matter (PM) Review Panel (experts charged with assisting the EPA’s latest review of PM). Acting Administrator Wheeler then tasked the seven-member Chartered Clean Air Scientific Advisory Committee (CASAC) to serve as the sole body to review the key scientific assessments for the National Ambient Air Quality Standards (NAAQS) Ozone and PM reviews. The CASAC does not have the breadth or depth of expertise needed for these reviews. No 7-person body can. These decisions have raised concerns about the outcome of these reviews and potential threats to the environment and public health.

In response, at the December 12, 2018, public meeting of CASAC, Environmental Protection Network members shared oral and written testimony critiquing these and other decisions.
