Clean Air Act Advisory Committee (CAAAC)

Learn about the CAAAC

The Clean Air Act Advisory Committee (CAAAC) is a senior-level policy committee established in 1990 to advise the U.S. EPA on issues related to implementing the Clean Air Act Amendments of 1990. 

The committee meets two times a year, normally in Washington, D.C.  The Assistant Administrator for the Office of Air and Radiation determines the committee agenda, and the CAAAC provides advice to the Agency on critical air quality policy issues during face-to-face meetings and through specific workgroup reports.


The committee is chartered under the Federal Advisory Committee Act and has been renewed every two years since its creation. Read the Charter, updated November 2, 2018.


The EPA Administrator is responsible for the establishment, management and termination of EPA’s Federal Advisory Committees (FACs). However, the EPA Administrator has delegated most of these responsibilities to other EPA personnel, though the Administrator remains accountable for ensuring compliance with the statutory and regulatory requirements throughout the life of the advisory committee. An EPA Administrator delegated authority to the EPA Deputy Administrator to approve membership packages for FACs.

The CAAAC has about 40 members representing senior managers and experts from state, tribal, and local government, environmental and public interest groups, academics, industry and others. Full Membership List.

EPA appreciates the efforts of all the applicants for CAAAC membership. Decisions on membership on the CAAAC and its subcommittees is at the discretion of the EPA with the intention to develop a diverse representative group to advise EPA on a variety of important air quality issues.
