SUPPLEMENTARY INFORMATION:

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 NO_X & SO_X Primary NAAQS Review Panel consists of the seven CASAC members augmented by subject-matter-experts. The CASAC Panel provides advice and recommendations to EPA concerning oxides of nitrogen and sulfur oxides in ambient air relevant to the Agency's review of the primary (health-based) NO₂ and SO₂ NAAQS. 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 NAAQS for the six “criteria” air pollutants, including NO_X and SO_X. The purpose of this public teleconference meeting is to conduct a consultation on the Agency's draft integrated plans for the reviews of the primary NO₂ and SO₂ NAAQS.

Availability of Meeting Materials: The Draft Integrated Plan for Review of the Primary NAAQS for NO₂ is posted on the Agency's Technology Transfer Network (TTN) Web site at http://www.epa.gov/​ttn/​naaqs/​standards/​nox/​s_​nox_​index.html, and the Draft Integrated Plan for Review of the Primary NAAQS for SO₂ is posted on the TTN Web site at http://www.epa.gov/​ttn/​naaqs/​standards/​so2/​s_​so2_​index.html. These draft integrated plans may be accessed in the “Documents from Current Review” section under “Planning Documents” on these respective Web pages.
