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 (NO<INF>X</INF>). EPA is in the process of reviewing the 
primary NAAQS for nitrogen dioxide (NO<INF>2</INF>), an indicator for 
NO<INF>X</INF>. 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 (NO<INF>2</INF>), CASAC met on 
September 9-10, 2008 to

Risk Characterization.'' The purpose of the teleconference is for CASAC

NO<INF>2</INF>, including the CASAC report on the Risk and Exposure

meeting, on the EPA Web site at http://www.epa.gov/casac.
