SUPPLEMENTARY INFORMATION: I. Information About the Workshop rwilkins on PROD1PC63 with NOTICES The Agency’s last review of the particulate matter (PM) national ambient air quality standards (NAAQS) was completed in September 2006 with the promulgation of revisions to some aspects of the PM standards to provide requisite protection of public health and welfare (71 FR 61144). Initiating the next review of these standards at this time is consistent with the Clean Air Act’s requirement that the Agency periodically review the latest scientific information and the standards. It is also consistent with the Agency’s new NAAQS review process.1 This workshop will provide an opportunity for external experts as well as EPA staff to highlight significant new and emerging PM research, and to make individual recommendations to the Agency regarding the design and scope of the review for the primary (healthbased) PM standards 2 to ensure that it addresses key policy-relevant issues and considers the new science relevant to informing our understanding of these issues. We intend that workshop discussions will build upon three prior publications or events: 3 1. Provisional Assessment of Recent Studies on Health Effects of Particulate Matter Exposure. This assessment, which was completed by EPA’s NCEA in July 2006, evaluated studies published too late for inclusion in the final PM criteria document in the last review. 2. National Ambient Air Quality Standards for Particulate Matter: Final 1 For more information on the NAAQS review process, please see https://www.epa.gov/ttn/naaqs/. 2 A similar workshop to discuss planning for the review of the secondary (welfare-based) PM NAAQS will be held on July 16, 2007 in Research Triangle Park. Please see announcement elsewhere in today’s Federal Register. 3 Please see https://www.epa.gov/air/ particlepollution/actions.html to obtain a copy of the provisional science assessment, the notice of final rulemaking, and other related documents. VerDate Aug<31>2005 18:25 Jun 19, 2007 Jkt 211001 Rule (71 FR 61144, October 17, 2006). The preamble to the final rule included detailed discussions of policy-relevant issues central to the last review. 3. Materials from the December 2006 workshop entitled, ‘‘Interpretation of Epidemiologic Studies of Multipollutant Exposure and Health Effects.’’ The workshop dealt with important issues relevant to this review, such as the interpretation and understanding of criteria air pollutant health effects analyses in population-level epidemiologic studies, with a focus on multi-pollutant exposures (71 FR 67566, November 22, 2006). Workshop participants are encouraged to review each of these documents and/or supporting materials thoroughly before the meeting begins, as they provide important insights into new scientific advances and key policyrelevant questions. Based in large part on the input received during this workshop, EPA intends to develop a draft integrated PM NAAQS review plan that will outline the schedule, process, and approaches for evaluating the relevant scientific information and addressing the key policy-relevant issues to be considered in this review. The Clean Air Scientific Advisory Committee (CASAC) will be asked to conduct a consultation with the Agency on the draft integrated plan later this year, and the public will have the opportunity to comment on it as well. The final integrated plan will be used to frame each of the major elements of the PM review under the new NAAQS process: an integrated science assessment document, a risk/exposure assessment report, and a policy assessment to be published as an advance notice of proposed rulemaking (ANPR).

SUPPLEMENTARY INFORMATION:

I. Summary of Information About the Workshops

    The U.S. Clean Air Act requires that EPA carry out periodic reviews 
of the national ambient air quality standards (NAAQS) for major 
``criteria'' air pollutants and to revise the NAAQS for a given 
pollutant, as appropriate. The Agency is in the process of reviewing 
the secondary (welfare-based) NAAQS for Oxides of Nitrogen 
(NOX) and Sulfur Oxides (SOX). EPA has recognized 
the merit of integrating the science assessment for these two 
pollutants, particularly for ecological and welfare effects, based on 
the important interrelationships for NOX and SOX 
in both their atmospheric chemistry and their effects on the 
environment. Therefore, EPA is conducting a joint

assessment of the secondary NAAQS for NOX and 
SOX.
    As part of the NAAQS reviews, the National Center for Environmental 
Assessment (NCEA) within EPA's Office of Research and Development (ORD) 
will assess newly available scientific information in Integrated 
Science Assessment (ISA) documents (formerly known as Air Quality 
Criteria Documents) that will be supported by more detailed and 
comprehensive annexes. The assessments in these documents are intended 
to provide the scientific bases for the reviews of the NAAQS. EPA's 
Office of Air Quality Planning and Standards (OAQPS) will prepare risk 
and exposure assessment analyses, as appropriate, drawing upon the 
scientific evidence summarized in the ISA. Subsequently, the EPA 
expects to prepare a policy assessment, to be published as an advance 
notice of proposed rulemaking, that will discuss, in part, the findings 
of the science and risk/exposure assessments related to the adequacy of 
the standards and describe a range of options for revising or retaining 
the NAAQS.
    EPA is holding this workshop to inform the Agency's assessment of 
the scientific evidence for the review of the secondary NAAQS for 
NOX and SOX. The workshop will address various 
issues involved in the preparation of the draft material for the ISA 
and annexes. This workshop is planned to help ensure that the ISA 
provides an up-to-date, state-of-the-art scientific basis for the 
review of the NAAQS. Workshop discussions will be focused on 
identifying and integrating scientific evidence that is relevant for 
future risk and exposure analyses to include in the ISA.
    This workshop is being held in conjunction with a workshop entitled 
``Workshop to Discuss Policy-Relevant Science to Inform EPA's 
Integrated Plan for the Review of the Secondary Particulate Matter (PM) 
National Ambient Air Quality Standards (NAAQS)'' (see accompanying 
Notice of Workshop).
