Clean Air Scientific Advisory Committee (CASAC)
The technical subcommittee of (CASAC) was established in 1996 to provide advice and comments to EPA on appropriate methods and network strategies for monitoring of fine particles in the context of implementating the revised national ambient air quality standards (NAAQS) for particulate matter.
