Notice of Workshop; Call for Information.
The U.S. Environmental Protection Agency (EPA) 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 primary and secondary National Ambient Air Quality Standards (NAAQS) for particulate matter (PM). This ISA is intended to update the scientific assessment presented in the Integrated Science Assessment for Particulate Matter (EPA 600/R-08/139F), published in December 2009. Interested parties are invited to assist EPA in developing and refining the scientific information base for the review of the PM NAAQS by submitting research studies that have been published, accepted for publication, or presented at a public scientific meeting.
EPA is also announcing that a workshop, entitled “Workshop to Discuss Policy-Relevant Science to Inform EPA's Review of the Primary and Secondary NAAQS for PM,” is being organized by NCEA and EPA Office of Air and Radiation's Office of Air Quality Planning and Standards (OAQPS). The workshop will be held February 9-February 11, 2015, 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 February 9-11, 2015. All communications and information submitted in response to the call for information should be received by EPA by February 18, 2015.
The workshop will be held at U.S. EPA, 109 T.W. Alexander Drive, Research Triangle Park, North Carolina. An EPA contractor, ICF International, is providing logistical support for the workshop.

I. Information About the Project
Section 108(a) of the Clean Air Act (CAA) directs the Administrator to identify and to list certain air pollutants and then to issue “air quality criteria” for those 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 pollutant in the ambient air . . .” Under section 109 of the CAA, 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 CAA 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.
Particulate matter (PM) is one of six “criteria” pollutants for which EPA has established 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 evidence and conclusions presented in the ISA directly inform the technical and policy assessments conducted by OAQPS. Collectively, these documents form the scientific and technical bases for EPA's decisions on the adequacy of existing NAAQS and the appropriateness of new or revised standards.
At the start of a NAAQS review, EPA issues an announcement of the review and notes the initiation of the development of the ISA. At that time, EPA also issues a request that the public submit scientific literature that they want to bring to the attention of the Agency for consideration in the review process. The Clean Air Scientific Advisory Committee (CASAC), an independent scientific advisory committee mandated by section 109(d)(2) of the Clean Air Act and part of EPA's Science Advisory Board (SAB), is charged with independent expert scientific review of EPA's draft ISAs and other technical and policy assessments. As the process proceeds, the public will have opportunities to review and comment on draft PM ISAs and other technical and policy assessments. These opportunities will also be announced in the Federal Register.
For the review of the PM NAAQS being initiated by this notice, the Agency is interested in obtaining additional new information, particularly concerning: (a) Toxicological studies of effects of controlled exposure to PM on laboratory animals and humans; (b) epidemiologic (observational) studies of health effects associated with ambient exposures of human populations to PM; (c) the quantification of light extinction in urban and non-urban areas—for example, new studies regarding visibility preferences, including studies in additional urban and non-urban areas that disentangle visibility preferences from health preferences, the sensitivity of visibility preferences to survey methods and/or preferences regarding intensity versus frequency of visibility impairment; (d) climate impacts from PM-related aerosols, particularly regarding the quantification of anthropogenic aerosol effects on radiative forcing; and (e) ecological studies that examine the effects on agricultural crops and natural terrestrial and/or aquatic ecosystems from ambient exposures to PM, including information regarding interactions with other ecosystem stressors and co-occurring pollutants. EPA also seeks recent information in other areas of PM research such as chemistry and physics, sources and emissions, analytical methodology, transport and transformation in the environment, and ambient concentrations. This and other selected literature relevant to a review of the NAAQS for PM will be assessed in the forthcoming PM ISA. It is important to note that for the evaluation of PM and ecological effects, this does not include studies that examine effects due to the deposition of oxides of nitrogen (NOX) or sulfur oxides (SOX) in the particulate form (e.g., ammonium sulfate), which will be covered in the ongoing review of the NOX/SOX secondary standard. 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.
As part of this review of the PM NAAQS, EPA intends to sponsor a workshop on February 9-February 11, 2015 to provide the opportunity for internal and external experts to highlight significant new and emerging PM research, and to make recommendations to the Agency regarding the design and scope of the review for the primary (health-based) and secondary (welfare-based) PM standards to ensure that it addresses key policy-relevant issues and considers the new and emerging science that is relevant to informing EPA's understanding of these issues. EPA intends that workshop discussions will build upon three prior publications (available at: http://www.epa.gov/ttn/naaqs/standards/pm/s_pm_index.html):
1. National Ambient Air Quality Standards for Particulate Matter: Final Rule (78 FR 2086, January 15, 2013). The preamble to the final rule included detailed discussions of policy-relevant issues central to the last review.
2. Integrated Science Assessment for PM—Final Report. (EPA/600/R-08/139F, December 2009). The ISA is a comprehensive review, synthesis, and evaluation of the most policy-relevant science, including key science judgments that are important to inform the development of the risk and exposure assessments, as well as other aspects of the NAAQS review. The 2009 PM ISA, completed by EPA's NCEA, included consideration of studies published through mid-2009.
3. Provisional Assessment of Recent Studies on Health Effects of Particulate Matter Exposure (EPA/600/R-12/056F, December 2012). This assessment, which was completed by EPA's NCEA, evaluated studies published too late for inclusion in the final PM ISA. The provisional science assessment focused on epidemiologic studies that used PM2.5 (i.e., fine PM) or PM10-2.5 (i.e., coarse PM) and were conducted in the U.S. or Canada, and toxicological or epidemiologic studies that compared effects of PM from different sources, PM components, or size fractions published through August 2012. The document was not intended to critically review individual studies or integrate the scientific findings to draw causal conclusions as is done for an ISA, but rather to ensure that the Administrator was fully aware of the “new” science that had developed since 2009 before making final decisions on whether to retain or revise the then-existing PM standards.
Workshop participants are encouraged to review these documents thoroughly before the meeting, as they provide important background information on the scientific findings and analytical approaches considered in the previous review, as well as insights into the key policy-relevant questions from that review. In addition, participants may also want to review related documents (available at: http://www.epa.gov/ttn/naaqs/standards/pm/s_pm_index.html), including the Policy Assessment for the Review of the Particulate Matter National Ambient Air Quality Standards (Final Report, April 2011), Quantitative Health Risk Assessment for Particulate Matter (Final Report, June 2010), and Particulate Matter Urban-Focused Visibility Start Printed Page 71766Assessment (Final Document, July 2010).
Based in large part on the input received during this workshop, EPA will develop a draft Integrated Review Plan (IRP) for the PM NAAQS. This draft IRP 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. CASAC will be asked to review the draft IRP in the mid-2015 and the public will also have the opportunity to comment on the draft plan. The final IRP, prepared in consideration of CASAC and public comments, will outline the process and schedule for conducting the review and the planned scope of the assessment documents (e.g., an ISA, a risk/exposure assessment, and a policy assessment) as well as the key policy-relevant issues/questions that will guide the review.
