Environmental Protection Agency.
Notice; call for information.
The U.S. Environmental Protection Agency (EPA) is announcing that the Office of Research and Development's National Center for Environmental Assessment (NCEA) is preparing an Integrated Science Assessment (ISA) as part of the review of the National Ambient Air Quality Standards (NAAQS) for ozone (O3). This is intended to update the scientific assessment presented in the “Air Quality Criteria for Ozone and Related Photochemical Oxidants” (EPA 600/P-05/004aF-cF), published in February 2006. Interested parties are invited to assist the EPA in developing and refining the scientific information base for the review of the O3 NAAQS by submitting research studies that have been published, accepted for publication, or presented at a public scientific meeting.
The EPA is also announcing that a workshop entitled, “Workshop to Discuss Policy-Relevant Science to Inform EPA's Integrated Plan for the Ozone NAAQS,” is being organized by NCEA and the EPA Office of Air and Radiation's Office of Air Quality Planning and Standards (OAQPS). The workshop will be held October 29-30, 2008, in Research Triangle Park, North Carolina. The workshop will be open to attendance by interested public observers on a first-come, first-served basis up to the limits of available space.
The workshop will be held on October 29 and 30, 2008. The pre-registration deadline is October 17, 2008. In response to the call for information, all communications and information should be received by EPA by November 3, 2008.
The workshop will be held at U.S. EPA, 109 T.W. Alexander Drive, Research Triangle Park, North Carolina. An EPA contractor, E.H. Pechan & Associates, Inc., is providing logistical support for the workshop. To register, please use the on-line registration form at: http://projects.pechan.com/epa/o3review/. Please direct questions regarding workshop registration or logistics to E. H. Pechan & Associates at 919-493-3144, ext. 119, or Tricia Crabtree at 919-541-5688, or e-mail: firstname.lastname@example.org. For specific questions regarding technical aspects of the workshop see the section of this notice entitled FOR FURTHER INFORMATION CONTACT.
Information in response to the call for information may be submitted electronically, by mail, by facsimile, or by hand delivery/courier. Please follow the detailed instructions as provided in the section of this notice entitled SUPPLEMENTARY INFORMATION.Start Further Info

I. Information About the Project
Section 108 (a) of the Clean Air Act directs the Administrator to issue “air quality criteria” for certain air pollutants. 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 such pollutants 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.
Ozone (O3) is one of six principal (or “criteria”) pollutants for which EPA has Start Printed Page 56582established NAAQS. Periodically, EPA reviews the scientific basis for these standards by preparing an Integrated Science Assessment (ISA), formerly called an Air Quality Criteria Document (AQCD). The ISA and supplementary annexes are the scientific basis for the additional technical and policy assessments that form the basis for EPA decisions on the adequacy of a current NAAQS and the appropriateness of new or revised standards. Early steps in this process include announcing the beginning of this periodic NAAQS review and the development of the ISA, and NCEA requesting that the public submit scientific literature that they want to bring to the attention of the Agency as it begins this process. The Clean Air Scientific Advisory Committee (CASAC), an independent science advisory committee mandated by the Clean Air Act and part of the EPA's Science Advisory Board (SAB), is charged with independent/expert scientific review of EPA's draft ISAs. As the process proceeds, the public will have opportunities to review and comment on draft O3 ISAs. These opportunities will also be announced in the Federal Register.
The Agency is interested in obtaining additional information, particularly concerning toxicological studies of effects of controlled exposure to O3 on laboratory animals, humans, and in vitro systems, as well as epidemiologic (observational) studies of health effects associated with ambient exposures of human populations to O3. EPA also seeks recent information in other areas of O3 research such as chemistry and physics, sources and emissions, analytical methodology, transport and transformation in the environment, ambient concentrations, and effects on public welfare or the environment. This and other selected literature relevant to a review of the NAAQS for O3 will be assessed in the forthcoming O3 ISA.
As part of this review of the O3 NAAQS, EPA intends to sponsor a workshop on October 29-30, 2008, to highlight significant new and emerging O3 research, and to make recommendations to the Agency regarding the design and scope of the review for the primary (health-based) and secondary (welfare) O3 standards to ensure that it addresses key policy-relevant issues and considers the new science that is relevant to informing our understanding of these issues. In addition, other opportunities for submission of new peer-reviewed, published (or in-press) papers will be possible as part of public comment on the draft ISAs that will be reviewed by CASAC. The workshop will provide an opportunity for internal and external experts to highlight significant new and emerging O3 research, and to make recommendations to the Agency regarding the design and scope of the review for the O3 standards 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:
1. National Ambient Air Quality Standards for Ozone: Final Rule (73 FR 16436, March 27, 2008). The preamble to the final rule included detailed discussions of policy-relevant issues central to the last review.
2. Air Quality Criteria for Ozone and Related Photochemical Oxidants (EPA 600/P-05/004aF-cF, February 2006). Please see http://www.epa.gov/ttn/naaqs/standards/o3/s_o3_index.html to obtain a copy of the 2006 Air Quality Criteria Document, the notice of final rulemaking from 2008, and other related documents.
3. December 2006 workshop sponsored by NCEA, entitled “Interpretation of Epidemiologic Studies of Multi-pollutant 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 policy-relevant questions.
Based in large part on the input received during this workshop, EPA will develop a draft integrated O3 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 CASAC will be asked to conduct a consultation with the Agency on the draft integrated plan early next 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 O3 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).
