CASAC and the CASAC documents cited below can be found on the EPA Web 
site at: http://www.epa.gov/casac.

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) as 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.
    EPA previously released an integrated plan for all aspects of this 
review of the primary NO2 standard, Integrated Review Plan 
for the Primary National Ambient Air Quality Standard for Nitrogen 
Dioxide (August 2007), which reflected advice provided by CASAC through 
a consultation, which resulted in the CASAC letter, Scientific Advisory 
Committee's (CASAC) Consultation on the Draft Integrated Plans for 
Review of the Primary NAAQS for NO2 and SO2 EPA-
CASAC-07-005. The CASAC also previously peer reviewed EPA's Integrated 
Science Assessment for Oxides of Nitrogen--Health Criteria (First 
External Review Draft) (EPA/600/R-07/093, August 2007) and issued a 
peer review report, Clean Air Scientific Advisory Committee's (CASAC) 
Peer Review of EPA's Integrated Science Assessment (ISA) for Oxides of 
Nitrogen--Health Criteria (First External Review Draft, August 2007), 
EPA-CASAC-08-002. The CASAC also provided consultative advice on the 
EPA's Nitrogen Dioxide Health Assessment Plan: Scope and Methods for 
Exposure and Risk Assessment and issued a consultation letter, Clean 
Air Scientific Advisory Committee's (CASAC) Consultation on EPA's 
Nitrogen Dioxide Health Assessment Plan: Scope and Methods for Exposure 
and Risk Assessment (September 2007 Draft), EPA-CASAC-08-001.
    As the next step in that review process, EPA's Office of Research 
and Development (ORD) has completed a draft document, Integrated 
Science Assessment for Oxides of Nitrogen--Health Criteria (Second 
External Review Draft) (EPA/600/R-07/093aB and EPA/600/R-07/903bB, 
March 2008) and has requested that CASAC review the document. EPA's 
Office of Air and Radiation (OAR) has also completed two draft 
documents entitled (1) Risk and Exposure Assessment to Support the 
Review of the NO2 Primary National Ambient Air Quality Standard: First 
Draft and (2) Risk and Exposure Assessment to Support the Review of the 
NO2 Primary National Ambient Air Quality Standard: Draft 
Technical Support Document (TSD). OAR has requested that CASAC review 
this assessment of human exposure and health risk for nitrogen dioxide 
(NO2). After the panel has drafted its reports, the 
chartered CASAC will meet by conference call to review and approve the 
drafts.
    Technical Contact: Any questions concerning EPA's Integrated 
Science Assessment for Oxides of Nitrogen--Health Criteria (Second 
External Review Draft) (EPA/600/R-07/093aB and EPA/600/R-07/903bB, 
March 2008) should be directed to Dr. Dennis Kotchmar, ORD (by 
telephone: (919) 541-4158, or e-mail: [email protected]). Any 
questions concerning EPA's Risk and Exposure Assessment To Support the 
Review of the NO2 Primary National Ambient Air Quality Standard: First 
Draft and Risk and Exposure Assessment To Support the Review of the NO2 
Primary National Ambient Air Quality Standard: Draft Technical Support 
Document (TSD) should be directed to Dr. Scott Jenkins, OAR (by 
telephone: (919) 541-1167, or e-mail: [email protected]).
