Background: The CASAC, which is comprised of seven members appointed by the EPA Administrator, was established under section 109(d)(2) of the Clean Air Act (CAA or Act) (42 U.S.C. 7409) as an independent scientific advisory committee. 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 Ozone Review Panel consists of the seven CASAC members supplemented by subject-matter-experts. The CASAC Ozone Review Panel provides advice and recommendations to EPA concerning ozone and related photochemical oxidants in ambient air. The Panel complies with the provisions of FACA and all appropriate SAB Staff Office procedural policies.

Section 109(d)(1) of the CAA requires that the Agency periodically review and revise, as appropriate, the air quality criteria and the national ambient air quality standards (NAAQS) for the six “criteria” air pollutants, including ambient ozone. Pursuant to sections 108 and 109 of the Act, EPA is in the process of reviewing the ozone NAAQS, which the Agency most recently revised in July 1997. EPA's Office of Air Quality Start Printed Page 77743Planning and Standards (OAQPS), within the Office of Air and Radiation (OAR), will publish a Final Ozone Staff Paper as part of its review of the ozone NAAQS. The Final Ozone Staff Paper evaluates the policy implications of the key scientific and technical information contained in the Agency's final Air Quality Criteria for Ozone and Related Photochemical Oxidants, Volumes I, II, and III, (EPA/600/R-05/004aF-cF, February 2006), and identifies critical elements that EPA believes should be considered in its review of the ozone NAAQS. The Ozone Staff Paper is intended to “bridge the gap” between the scientific review contained in the Ozone Air Quality Criteria Document (AQCD) and the public health and welfare policy judgments required of the EPA Administrator in reviewing the ozone NAAQS. EPA solicited advice and recommendations from the CASAC Panel on the First Draft Ozone Staff Paper (November 2005) in a public meeting on December 8, 2005, in Durham, NC. The CASAC's letter to the EPA Administrator (EPA-CASAC-CON-06-003, dated February 16, 2006) is posted on the SAB Web Site at​sab/​pdf/​casac_​con_​06_​003.pdf. In addition, EPA solicited the Panel's advice and recommendations on the Second Draft Ozone Staff Paper (July 2006) in a public meeting on August 24-25, 2006, in Durham, NC. The CASAC's letter to the Administrator (EPA-CASAC-07-001, dated October 24, 2006) is posted on the SAB Web site at​sab/​pdf/​casac-07-001.pdf. In that letter, the CASAC indicated it would review the Agency's Final Ozone Staff Paper and offer additional, unsolicited advice to the Agency on Chapter 6 (The Primary O3 NAAQS) and Chapter 8 (The Secondary O3 NAAQS). The purpose of such advice is to advise EPA as it develops a proposed rule for ozone and related photochemical oxidants. This teleconference meeting continues the CASAC Ozone Review Panel's advisory activities in the current review cycle for the ozone NAAQS.
