SUPPLEMENTARY INFORMATION: Under section 108(a) of the Clean Air Act (CAA), the Administrator identifies and lists certain pollutants which ‘‘cause or contribute to air pollution which may reasonably be anticipated to endanger public health or welfare.’’ The EPA then issues air quality criteria for listed pollutants, which are commonly referred to as ‘‘criteria pollutants.’’ The air quality criteria are to ‘‘accurately reflect the latest scientific knowledge useful in indicating the kind and extent of all identifiable effects on public health or welfare which may be expected from the presence of [a] pollutant in the ambient air, in varying quantities.’’ Under section 109 of the CAA, EPA establishes national ambient air quality standards (NAAQS) for each listed pollutant, with the NAAQS based on the air quality criteria. Section 109(d) of the CAA requires periodic review and, if appropriate, revision of existing air quality criteria. The revised air quality criteria reflect advances in scientific knowledge on the effects of the pollutant on public health or welfare. The EPA is also required to periodically review and revise the NAAQS, if appropriate, based on the revised criteria. Air quality criteria have been established for the nitrogen oxides (NOX) and NAAQS have been established for nitrogen dioxide (NO2), an indicator for gaseous NOX. Presently, PO 00000 Frm 00035 Fmt 4703 Sfmt 4703 EPA is in the process of reviewing the NAAQS for NO2. As part of its review of the NAAQS, EPA is preparing an assessment of exposures and health risks associated with ambient NO2. A draft plan describing the proposed approaches to assessing exposures and risks is described in the draft document, Nitrogen Dioxide Health Assessment Plan: Scope and Methods for Exposure and Risk Assessment. This document was released for public review and comment in September 2007 and was the subject of a consultation with the Clean Air Scientific Advisory Committee (CASAC) on October 24 and 25, 2007. Comments received from that consultation were considered in developing the document titled, Risk and Exposure Assessment to Support the Review of the NO2 Primary National Ambient Air Quality Standard: First Draft, which was released for public review and comment in April 2008.

The EPA has solicited advice and recommendations from the CASAC by means of a review of the draft document at a public meeting to be held on September 9–10, 2008 in Research Triangle Park, North Carolina. A separate Federal Register notice will provide additional details about this meeting and the process for participation. In preparing a final risk and exposure assessment report, EPA will consider comments received from the CASAC and the public at this upcoming meeting. Dated: August 7, 2008.

SUPPLEMENTARY INFORMATION: Under section 108(a) of the Clean Air Act 
(CAA), the Administrator identifies and lists certain pollutants which 
``cause or contribute to air pollution which may reasonably be 
anticipated to endanger public health or welfare.'' The EPA then issues 
air quality criteria for listed pollutants, which are commonly referred 
to as ``criteria pollutants.'' The air quality criteria are to 
``accurately reflect the latest scientific knowledge useful in 
indicating the kind and extent of all identifiable effects on public 
health or welfare which may be expected from the presence of [a] 
pollutant in the ambient air, in varying quantities.'' Under section 
109 of the CAA, EPA establishes national ambient air quality standards 
(NAAQS) for each listed pollutant, with the NAAQS based on the air 
quality criteria. Section 109(d) of the CAA requires periodic review 
and, if appropriate, revision of existing air quality criteria. The 
revised air quality criteria reflect advances in scientific knowledge 
on the effects of the pollutant on public health or welfare. The EPA is 
also required to periodically review and revise the NAAQS, if 
appropriate, based on the revised criteria.
    Air quality criteria have been established for the nitrogen oxides 
(NOX) and NAAQS have been established for nitrogen dioxide 
(NO2), an indicator for gaseous NOX. Presently, 
EPA is in the process of reviewing the NAAQS for NO2. As 
part of its review of the NAAQS, EPA is preparing an assessment of 
exposures and health risks associated with ambient NO2. A 
draft plan describing the proposed approaches to assessing exposures 
and risks is described in the draft document, Nitrogen Dioxide Health 
Assessment Plan: Scope and Methods for Exposure and Risk Assessment. 
This document was released for public review and comment in September 
2007 and was the subject of a consultation with the Clean Air 
Scientific Advisory Committee (CASAC) on October 24 and 25, 2007. 
Comments received from that consultation were considered in developing 
the document titled, Risk and Exposure Assessment to Support the Review 
of the NO2 Primary National Ambient Air Quality Standard: First Draft, 
which was released for public review and comment in April 2008. This 
document was the subject of a CASAC review on May 1 and 2, 2008. 
Comments received from that review have been considered in developing 
the document titled, Risk and Exposure Assessment to Support the Review 
of the NO2 Primary National Ambient Air Quality Standard: Second Draft, 
which is being released at this time.
    This draft document is available online at: https://www.epa.gov/ttn/
naaqs/standards/nox/s_nox_cr_rea.html. It has two primary purposes: 
To convey the approaches taken to characterize exposures and risks 
associated with ambient NO2, and to present the results of 
these analyses. The EPA has solicited advice and recommendations from 
the CASAC by means of a review of the draft document at a public 
meeting to be held on September 9-10, 2008 in Research Triangle Park, 
North Carolina. A separate Federal Register notice will provide 
additional details about this meeting and the process for 
participation. In preparing a final risk and exposure assessment 
report, EPA will consider comments received from the CASAC and the 
public at this upcoming meeting.
