Information About the Document Section 108(a) of the Clean Air Act directs the Administrator to identify certain pollutants which ‘‘may reasonably be anticipated to endanger public health and welfare’’ and to issue air quality criteria for them. These 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.’’ Under section 109 of the Act, EPA is then to establish national ambient air quality standards (NAAQS) for each pollutant for which EPA has issued criteria. Section 109(d) of the Act subsequently requires periodic review and, if appropriate, revision of existing air quality criteria to reflect advances in scientific knowledge on the effects of the pollutant on public health and welfare. EPA is also to revise the NAAQS, if appropriate, based on the revised air quality criteria. Oxides of nitrogen and sulfur are two of six principal (or ‘‘criteria’’) pollutants for which EPA has established air quality criteria and NAAQS. EPA periodically reviews the scientific basis for these standards by preparing an Integrated Science Assessment (ISA) (formerly called an Air Quality Criteria Document). The ISA and supplementary annexes, in conjunction with additional technical and policy assessments, provide the scientific basis for EPA decisions on the adequacy of a current NAAQS and the appropriateness of new or revised standards.

EPA formally initiated its current review of the criteria for oxides of nitrogen and sulfur in December 2005 (70 FR 73236) and May 2006 (71 FR 28023) respectively, requesting the submission of recent scientific information on specified topics. In the initial stages of the criteria reviews, EPA recognized the merit of integrating the science assessment for these two pollutants due to their combined effects on atmospheric chemistry, deposition processes, and environment-related public welfare effects. In July 2007 (72 FR 34004), a workshop was held to discuss, with invited scientific experts, initial draft materials prepared in the development of the ISA and supplementary annexes for oxides of nitrogen and sulfur. EPA’s ‘‘Draft Plan for Review of the Secondary National Ambient Air Quality Standards for Nitrogen Dioxide and Sulfur Dioxide’’ was made available in September 2007 for public comment and was discussed by the Clean Air Scientific Advisory Committee (CASAC) via a publicly accessible teleconference consultation on October 30, 2007 (72 FR 57568). The Plan is being finalized and will be made available on EPA’s Web site http:// www.epa.gov/ttn/naaqs/standards/ no2so2sec/cr_pd.html. The draft, ‘‘Integrated Science Assessment for Oxides of Nitrogen and Sulfur—Environmental Criteria; First External Review Draft,’’ will be discussed by CASAC at a future public meeting; public comments that have been received prior to the public meeting will be provided to the CASAC review panel.

SUPPLEMENTARY INFORMATION: 

I. Information About the Document

    Section 108(a) of the Clean Air Act directs the Administrator to 
identify certain pollutants which ``may reasonably be anticipated to 
endanger public health and welfare'' and to issue air quality criteria 
for them. These 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.''
    Under section 109 of the Act, EPA is then to establish national 
ambient air quality standards (NAAQS) for each pollutant for which EPA 
has issued criteria. Section 109(d) of the Act subsequently requires 
periodic review and, if appropriate, revision of existing air quality 
criteria to reflect advances in scientific knowledge on the effects of 
the pollutant on public health and welfare. EPA is also to revise the 
NAAQS, if appropriate, based on the revised air quality criteria.
    Oxides of nitrogen and sulfur are two of six principal (or 
``criteria'') pollutants for which EPA has established air quality 
criteria and NAAQS. EPA periodically reviews the scientific basis for 
these standards by preparing an Integrated Science Assessment (ISA) 
(formerly called an Air Quality Criteria Document). The ISA and 
supplementary annexes, in conjunction with additional technical and 
policy assessments, provide the scientific basis for EPA decisions on 
the adequacy of a current NAAQS and the appropriateness of new or 
revised standards. The Clean Air Scientific Advisory Committee (CASAC), 
an independent science advisory committee established pursuant to 
section 109 of the Clean Air Act and part of the EPA's Science Advisory 
Board (SAB), provides

independent scientific advice on NAAQS matters, including advice on 
EPA's draft ISAs.
    EPA formally initiated its current review of the criteria for 
oxides of nitrogen and sulfur in December 2005 (70 FR 73236) and May 
2006 (71 FR 28023) respectively, requesting the submission of recent 
scientific information on specified topics. In the initial stages of

is being finalized and will be made available on EPA's Web site http://

    The draft, ``Integrated Science Assessment for Oxides of Nitrogen
