Notice of public comment period.
The U.S. Environmental Protection Agency (EPA) is announcing the availability of a document titled, “First External Review Draft Integrated Science Assessment for Lead” (EPA/600/R-10/075A). This draft document was prepared by the National Center for Environmental Assessment (NCEA) within EPA's Office of Research and Development as part of the review of the national ambient air quality standards (NAAQS) for lead (Pb).
EPA is releasing this draft document to seek review by the Clean Air Scientific Advisory Committee (CASAC) and the public (meeting date and location to be specified in a separate Federal Register Notice). The draft document does not represent and should not be construed to represent any final EPA policy, viewpoint, or determination. EPA will consider any timely public comments submitted in response to this notice when revising the document.
The public comment period begins May 6, 2011, and ends July 5, 2011. Comments must be received on or before July 5, 2011.
The “First External Review Draft Integrated Science Assessment for Lead” will be available primarily via the Internet on the National Center for Environmental Assessment's home page under the Recent Additions and Publications menus at http://www.epa.gov/ncea. A limited number of CD-ROM or paper copies will be available. Contact Ms. Debbie Wales by phone (919-541-4731), fax (919-541-5078), or e-mail (email@example.com) to request either of these, and please provide your name, your mailing address, and the document title, “First External Review Draft Integrated Science Assessment for Lead” (EPA/600/R-10/075A) to facilitate processing of your request.Start Further Info

I. Information About the Document
Two sections of the Clean Air Act (CAA) govern the establishment and revision of the NAAQS. Section 108 (42 U.S.C. section 7408) directs the Administrator to identify and list certain air pollutants and then to issue air quality criteria for those pollutants. The Administrator is to list those air pollutants that in her “judgment, cause or contribute to air pollution which may reasonably be anticipated to endanger public health or welfare;” “the presence of which in the ambient air results from numerous or diverse mobile or stationary sources;” and “for which * * * [the Administrator] plans to issue air quality criteria * * *.” Air quality criteria are intended 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* * *.” 42 U.S.C. 7408(b). Under section 109 (42 U.S.C. 7409) the Administrator is to establish national ambient air quality standards (NAAQS) for each pollutant for which EPA has issued criteria. Section 109(d)(1) 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 or welfare. EPA is also to revise the NAAQS, if appropriate, based on the revised air quality criteria. Section 109(d)(2) requires that an independent scientific review committee “shall complete a review of the criteria * * * and the national primary and secondary ambient air quality standards * * * and shall recommend to the Administrator any new * * * standards and revisions of existing criteria and standards as may be appropriate . * * *” Since the early 1980's, this independent review function has been performed by the Clean Air Scientific Advisory Committee (CASAC).
Under the current NAAQS review process, EPA reviews the scientific basis for the NAAQS by preparing an Integrated Science Assessment (ISA) and supplementary materials (formerly called an Air Quality Criteria Document). On February 26, 2010 (75 FR 8934), EPA formally initiated its current review of the air quality criteria for Pb, requesting the submission of recent scientific information on specified topics. A workshop was held on May 10-11, 2010 (75 FR 20843) to discuss policy-relevant science to inform EPA's planning for the Pb NAAQS review. Following the workshop, a draft of EPA's “Integrated Review Plan for the National Ambient Air Quality Standards for Lead” (EPA-452/D-11-001) was made available in late March, 2011 for public comment and consultation with CASAC. It will be discussed by the CASAC via a publicly accessible teleconference consultation on May 5, 2011 (76 FR 21346). In December 2010, EPA held a workshop (75 FR 69078) to discuss, with invited scientific experts, preliminary draft materials prepared during the ongoing development of the Pb ISA.
The first external review draft ISA for Pb will be discussed at a public meeting for review by CASAC, and public comments received will be provided to the CASAC review panel. A future Federal Register notice will inform the public of the exact date and time of that CASAC meeting.
