Clean Air Scientific Advisory Committee (CASAC)

The Clean Air Scientific Advisory Committee (CASAC) is a group of independent experts that provides advice to the U.S. Environmental Protection Agency (EPA) on air pollution standards. They review scientific research to ensure that air quality standards protect public health and the environment. CASAC helps the EPA make informed decisions about setting limits on pollutants like ozone and particulate matter, balancing scientific evidence with practical considerations. Their role is essential in maintaining air quality protections that safeguard everyone's health, especially vulnerable populations.
