[Federal Register Volume 75, Number 38 (Friday, February 26, 2010)] [Notices] [Pages 8934-8935] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 2010-3970] ======================================================================= ----------------------------------------------------------------------- ENVIRONMENTAL PROTECTION AGENCY [FRL-9115-6; Docket ID No. EPA-HQ-OAR-2010-0108] Integrated Science Assessment for Lead (Pb) AGENCY: Environmental Protection Agency. ACTION: Notice; call for information. ----------------------------------------------------------------------- SUMMARY: The 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 Lead (Pb). This ISA is intended to update and revise, where appropriate, the scientific assessment presented in the Air Quality Criteria for Lead (EPA/600/R-5/144aF), published on October 1, 2006. Interested parties are invited to assist the EPA in developing and refining the scientific information base for the review of the Pb NAAQS 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 received by EPA by April 30, 2010. 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 the period for submission of research information from the public, contact the Office of Environmental Information (OEI) Docket; telephone: 202-566-1752; facsimile: 202-566-1753; or e-mail: [email protected]. For technical information, contact Ellen Kirrane, Ph.D., NCEA, telephone, 919-541- 1340; facsimile: 919-541-2985; or e-mail: [email protected]. SUPPLEMENTARY INFORMATION: I. Information About the Project Section 108 (a) of the Clean Air Act directs the Administrator to identify pollutants that meet certain criteria, including emissions which ``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 such pollutant in the ambient air * * *.'' Welfare effects as defined in section 302(h) (42 U.S.C. 7602(h)) include, but are not limited to, ``effects on soils, water, crops, vegetation, man-made materials, animals, wildlife, weather, visibility and climate, damage to and deterioration of property, and hazards to transportation, as well as effects on economic values and on personal comfort and well-being.'' 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. Lead (Pb) 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 ISA and its supplementary annexes are the scientific basis for the additional technical and policy assessments that form the basis for EPA decisions on the adequacy of 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 EPA 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 drafts of the Pb ISA. These opportunities will also be announced in the Federal Register. The Agency is interested in obtaining information concerning toxicological studies of effects of controlled exposure to Pb on laboratory animals and in vitro systems, epidemiologic (observational) studies of health effects associated with exposures of human populations to Pb, and ecological effects of Pb exposure. Information particular to air-related [[Page 8935]] pathways, including those involving deposition, are also of interest to the Agency. EPA also seeks recent information in other areas of Pb research such as toxicokinetic modeling, exposure assessment and exposure assessment methodologies, sources and emissions, chemistry and physics, analytical methodology, fate and transport in the environment, ambient concentrations, including concentration changes in response to changes in Pb deposition, and effects on public welfare or the environment. This and other selected literature relevant to a review of the NAAQS for Pb will be assessed in the forthcoming Pb ISA. As part of this review of the Pb NAAQS, EPA intends to sponsor a workshop in May 2010, which will be announced in the Federal Register, to highlight significant new and emerging Pb research, and to make recommendations to the Agency regarding the design and scope of the review of the air quality criteria and the primary (health-based) and secondary (welfare-based) Pb 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. II.
