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 NO2and 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 NO2Primary National Ambient Air Quality Standard: First Draft and (2) Risk and Exposure Assessment to Support the Review of the NO2Primary 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 Start Printed Page 19838Draft) (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: Kotchmar.dennis@epa.gov). Any questions concerning EPA's Risk and Exposure Assessment to Support the Review of the NO 2 Primary National Ambient Air Quality Standard: First Draft and Risk and Exposure Assessment to Support the Review of the NO2Primary 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: jenkins.scott@epa.gov).
