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 VerDate Nov<24>2008 13:08 May 20, 2009 Jkt 217001 periodically review and revise the NAAQS, if appropriate, based on the revised criteria. Air quality criteria have been established for the sulfur oxides (SOX) and NAAQS have been established for sulfur dioxide (SO2), an indicator for SOX. Presently, EPA is reviewing the air quality criteria for SOX and the NAAQS for SO2. As part of its review of the NAAQS, EPA has prepared an assessment of exposures and characterization of health risks associated with ambient SO2. Planned approaches to assessing exposures and characterizing risks were described in the document, Sulfur Dioxide Health Assessment Plan: Scope and Methods for Exposure and Risk Assessment. This planning document was released for public review and comment in November 2007 and was the subject of a consultation with the Clean Air Scientific Advisory Committee (CASAC) on December 5 and 6, 2007. Comments received from that consultation were considered in developing the ‘‘Risk and Exposure Assessment to Support the Review of the SO2 Primary National Ambient Air Quality Standards: First Draft,’’ which was released in July 2008. The second draft of this document was released in March 2009 and conveys the approach taken to assess exposures to ambient SO2 and to characterize associated health risks, as well as to present the results of those assessments. In addition, this document also contains a staff policy assessment that considers the evidence presented in the final Integrated Science Assessment and the exposure and risk characterization results presented in this second draft document, as they relate to the adequacy of the current SO2 NAAQS and any potential alternative primary SO2 standards.

(CAA), the Administrator identifies and lists certain pollutants which 
``cause or contribute to air pollution which may reasonably be

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
