SUPPLEMENTARY INFORMATION:

Background: The Clean Air Scientific Advisory Committee (CASAC) 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. CASAC provides advice, information, and recommendations on the scientific and technical aspects of air quality criteria and national ambient air quality standards (NAAQS) under sections 108 and 109 of the Act. The CASAC is a Federal advisory committee chartered under the Federal Advisory Committee Act (FACA), as amended, 5 U.S.C., App. The Panel will comply 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 oxides of nitrogen (NOX). EPA is in the process of reviewing the primary NAAQS for nitrogen dioxide (NO2), an indicator for NOX. Primary standards set limits to protect public health, including the health of “sensitive” populations such as asthmatics, children, and the elderly.

As part of its scientific advice to support EPA's review of the primary NAAQS for nitrogen dioxide (NO2), CASAC met on September 9-10, 2008 to conduct a peer review of the Risk and Exposure Assessment to Support the Review of the NO2Primary National Ambient Air Quality Standard: Second Draft (73 FR 43444-43445). At that time, EPA had not completed chapter eight of the draft assessment entitled “Exposure and Health Risk Characterization.” CASAC also held a public teleconference on October 22, 2008 to conduct a peer review of the draft chapter 8 (73 FR 55074-55075).

The public may access completed CASAC advisory reports related to the primary NO2 NAAQS, including the CASAC reports on the Risk and Exposure Assessment to Support the Review of the NO2Primary National Ambient Air Quality Standard: Second Draft, on the EPA Web site at http://yosemite.epa.gov/​sab/​sabproduct.nsf/​WebReportsbyTopicCASAC!OpenView.

EPA now plans that the final document will include an additional chapter (chapter 10) that considers the scientific evidence and exposure-risk-based information specifically as it relates to the current and potential alternative standards. At the December 5, 2008 teleconference, the CASAC will review EPA's completed Risk and Exposure Assessment and provide advice for EPA to consider as it develops its Advance Notice for Proposed Rulemaking for nitrogen dioxide.

Technical Contact: Any questions concerning Risk and Exposure Assessment to Support the Review of the NO2Primary National Ambient Air Quality Standard should be directed to Dr. Scott Jenkins, OAR (by telephone (919) 541-1167 or e-mail jenkins.scott@epa.gov.
