ACTION: Notice; call for information. AGENCY: mstockstill on PROD1PC66 with NOTICES SUMMARY: The U.S. Environmental Protection Agency (EPA), Office of Research and Development 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 particulate matter (PM). This ISA is intended to update and revise, where appropriate, the scientific assessment presented in the Air Quality Criteria for Particulate Matter (PM), EPA/600/P–99/ 002aF–bF, published in October 2004. Interested parties are invited to assist the EPA in developing and refining the scientific information base for PM by submitting research studies that have been published, accepted for publication, or presented at a public scientific meeting. DATES: All communications and information should be submitted by August 27, 2007. ADDRESSES: 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. FOR FURTHER INFORMATION CONTACT: For details on submitting research information from the public, contact the Office of Environmental Information (OEI) Docket; telephone: 202–566–1752; facsimile: 202–566–1753; or e-mail: ORD.Docket@epa.gov. For technical information, contact Lori White, PhD, NCEA; telephone: 919–541–3146; facsimile: 919–541–1818; or e-mail: white.lori@epa.gov. SUPPLEMENTARY INFORMATION: I. Information About the Project Section 108(a) of the Clean Air Act (CAA) directs the Administrator to identify certain pollutants which ‘‘in his judgment, may reasonably be anticipated to endanger public health and welfare’’ and whose ‘‘presence * * * in the ambient air results from numerous or diverse mobile or stationary sources’’ and to issue air quality criteria for them. These air quality criteria are to ‘‘accurately reflect the latest scientific knowledge useful in VerDate Aug<31>2005 18:23 Jun 27, 2007 Jkt 211001 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 CAA, EPA establishes National Ambient Air Quality Standards (NAAQS) for each pollutant for which EPA has issued criteria. Section 109(d) 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 then to revise the NAAQS, if appropriate, based on the revised air quality criteria. Particulate matter is one of six principal (or ‘‘criteria’’) pollutants for which EPA has established NAAQS. Periodically, EPA reviews the scientific basis for these standards by preparing an Integrated Science Assessment (ISA), historically referred to as an Air Quality Criteria Document (AQCD). The ISA and supplementary annexes are the scientific bases 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 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 whose function is mandated by section 109(d)(2) of the CAA, 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 the draft PM ISA. These opportunities will also be announced in the Federal Register. Since completion of the 2004 Air Quality Criteria for PM, EPA has continued to follow the scientific research on PM exposure and its effects on health and the environment. On July 21, 2006, EPA published a Provisional Assessment of Recent Studies on Health Effects of Particulate Matter Exposure (EPA/600/ R–06/063) which presents findings of EPA’s survey and provisional assessment of studies relevant to assessing the health effects of PM that were published too recently to be included in the 2004 PM AQCD. (71 FR 41409–10) The Agency is interested in obtaining additional new information relevant to this review of the NAAQS for PM. We are especially interested in information concerning: (a) Toxicological studies of PO 00000 Frm 00041 Fmt 4703 Sfmt 4703 effects of controlled exposure to PM on laboratory animals, humans, and in vitro systems; (b) epidemiologic (observational) studies of health effects associated with ambient exposures of human populations to PM; and (c) ecological studies of the effects on agricultural crops and natural terrestrial and/or aquatic ecosystems of ambient exposures to PM. 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. One or more drafts of the PM ISA are expected to be made available by EPA for public comment and CASAC review during 2008 and 2009. Other opportunities for submission of new peer-reviewed, published (or in-press) papers will be possible as part of public comment on the additional draft documents that will be reviewed by CASAC. As part of this review of the PM NAAQS, EPA is also sponsoring a workshop entitled, ‘‘Workshop to Discuss Policy-Relevant Science to Inform EPA’s Integrated Plan for the Review of the Primary Particulate Matter (PM) National Ambient Air Quality Standards (NAAQS)’’ 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) PM 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.

ACTION: Notice. AGENCY: SUMMARY: The EPA Science Advisory Board (SAB) Staff Office announces the formation of SAB Panels to address issues related to uncertainty analysis and expert elicitation and is soliciting nominations for members of the Panels. DATES: Nominations should be submitted by July 19, 2007 per the instructions below. FOR FURTHER INFORMATION CONTACT: Members of the public who wish to obtain further information regarding this announcement may contact Dr. Angela Nugent, Designated Federal Officer, via telephone at: (202) 343–9981 or e-mail at: nugent.angela@epa.gov. The SAB mailing address is: U.S. EPA Science Advisory Board (1400F), U.S. Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460. General information about the SAB as well as any updates concerning this request for nominations may be found on the SAB Web site at: https://www.epa.gov/sab. SUPPLEMENTARY INFORMATION: There has been a recent increase in interest in the use of uncertainty analysis and expert elicitation as tools to be used in regulatory analyses and in support of EPA decision-making. At the request of EPA’s Office of Air and Radiation and Office of the Science Advisor, the SAB plans to form several expert panels, as needed, to provide technical advice to EPA through the chartered SAB regarding the Agency’s ongoing work in uncertainty analyses and expert elicitation. The SAB is a chartered Federal Advisory Committee, established by 42 U.S.C. 4365, to provide independent scientific and technical advice, consultation, and recommendations to the EPA PO 00000 Frm 00042 Fmt 4703 Sfmt 4703 35463 Administrator on the technical bases for EPA policies and actions. The SAB expert panels to be formed to address scientific issues related to uncertainty analysis and expert elicitation will comply with the provisions of the Federal Advisory Committee Act (FACA) and all appropriate SAB procedural policies. Several specific reports have called for increased attention to quantitative uncertainty analysis and expert elicitation. In 2002, the National Research Council (NRC) published a Report to Congress, titled ‘‘Estimating the Health-Risk-Reduction Benefits of Proposed Air Pollution Regulations.’’ One of the recommendations of the NRC was that ‘‘EPA should begin to move the assessment of uncertainties from its ancillary analyses into the primary analysis by conducting probabilistic, multiple-source uncertainty analyses. This shift will require specification of probability distributions for major sources of uncertainty. These distributions should be based on available data and expert judgment.’’ More recently, the Office of Management and Budget (OMB) suggested using expert elicitation as a tool in addressing Circular A–4 requirements (OMB, 2004) for probabilistic uncertainty analysis and also discussed its use in a Proposed Risk Assessment Bulletin (OMB, 2006). Provisions for expert elicitation were also included in EPA’s recently revised cancer guidelines (2005). EPA’s experience conducting expert elicitations has been limited, with the majority of experience in the Office of Air and Radiation. The SAB Staff Office has received requests for advice from the SAB on four new advisory activities related to implementation of methods related to uncertainty analysis and expert elicitation. These four activities are summarized below. EPA’s Office of Air and Radiation has requested SAB review of a draft document, ‘‘Hierarchy of Methods Report,’’ that catalogues quantitative and qualitative methods available for characterizing uncertainty in risk assessments and regulatory impact analyses. The document provides guidance for selecting methods, given the type of uncertainty being addressed, the quantity and type of available evidence or data, and the ability to gather additional data. The document summarizes data requirements associated with different methods, resource needs, experience and acceptability, and other considerations on their use to support regulatory decisions.

SUPPLEMENTARY INFORMATION: 

I. Information About the Project

    Section 108(a) of the Clean Air Act (CAA) directs the Administrator 
to identify certain pollutants which ``in his judgment, may reasonably 
be anticipated to endanger public health and welfare'' and whose 
``presence * * * in the ambient air results from numerous or diverse 
mobile or stationary sources'' 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 CAA, EPA establishes National Ambient Air Quality 
Standards (NAAQS) for each pollutant for which EPA has issued criteria. 
Section 109(d) 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 then to revise the NAAQS, if appropriate, based on the revised 
air quality criteria.
    Particulate matter is one of six principal (or ``criteria'') 
pollutants for which EPA has established NAAQS. Periodically, EPA 
reviews the scientific basis for these standards by preparing an 
Integrated Science Assessment (ISA), historically referred to as an Air 
Quality Criteria Document (AQCD). The ISA and supplementary annexes are 
the scientific bases 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 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 whose function is mandated by section 109(d)(2) of the CAA, 
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 the draft PM ISA. These opportunities will also 
be announced in the Federal Register. Since completion of the 2004 Air 
Quality Criteria for PM, EPA has continued to follow the scientific 
research on PM exposure and its effects on health and the environment. 
On July 21, 2006, EPA published a Provisional Assessment of Recent 
Studies on Health Effects of Particulate Matter Exposure (EPA/600/R-06/
063) which presents findings of EPA's survey and provisional assessment 
of studies relevant to assessing the health effects of PM that were 
published too recently to be included in the 2004 PM AQCD. (71 FR 
41409-10)
    The Agency is interested in obtaining additional new information 
relevant to this review of the NAAQS for PM. We are especially 
interested in information concerning: (a) Toxicological studies of 
effects of controlled exposure to PM on laboratory animals, humans, and 
in vitro systems; (b) epidemiologic (observational) studies of health 
effects associated with ambient exposures of human populations to PM; 
and (c) ecological studies of the effects on agricultural crops and 
natural terrestrial and/or aquatic ecosystems of ambient exposures to 
PM. 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. One or more drafts of the PM ISA are expected to be made available 
by EPA for public comment and CASAC review during 2008 and 2009. Other 
opportunities for submission of new peer-reviewed, published (or in-
press) papers will be possible as part of public comment on the 
additional draft documents that will be reviewed by CASAC. As part of 
this review of the PM NAAQS, EPA is also sponsoring a workshop 
entitled, ``Workshop to Discuss Policy-Relevant Science to Inform EPA's 
Integrated Plan for the Review of the Primary Particulate Matter (PM) 
National Ambient Air Quality Standards (NAAQS)'' 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) PM 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. (72 FR 34003-04).
