11 October 2018 (Silencing Science Tracker) – On 11 October 2018, the Environmental Protection Agency (EPA) disbanded the particulate matter (PM) review panel. In the past, the panel has provided advice to EPA’s Clean Air Scientific Advisory Committee (CASAC), which is responsible for reviewing the National Ambient Air Quality Standards (NAAQS) for criteria pollutants. Under the Clean Air Act, CASAC is required to periodically review the NAAQS, and recommend appropriate changes thereto to protect public health. When reviewing the NAAQS for PM, CASAC has historically relied on advice from the PM review panel, which is comprised of two dozen university researchers and others with special expertise on the health effects of PM. The panel will not, however, have a role in CASAC’s next review. On 11 October 2018, EPA sent an email to panel members, informing them that “the CASAC PM Review Panel will no longer be involved with the Agency’s PM NAAQS Review and your service on the panel has concluded.”
