The CASAC provides advice, information and recommendations on the scientific and technical aspects of issues related to air quality criteria and NAAQS under sections 108 and 109 of the Act. The CASAC is chartered under the Federal Advisory Committee Act (FACA), as amended, 5 U.S.C., App. The CASAC NOX                     & SOX                     Primary NAAQS Review Panel consists of the seven CASAC members augmented by subject-matter-experts.
