The Clean Air Scientific Advisory Committee (CASAC) was established under section 109(d)(2) of the Clean Air Act (CAA or Act) (42 U.S.C. 7409) as an independent scientific advisory committee. CASAC provides advice, information and recommendations on the scientific and technical aspects of air quality criteria and national ambient Start Printed Page 53002air quality standards (NAAQS) under sections 108 and 109 of the Act. The CASAC Lead Review Panel will consist of the seven members of the chartered CASAC, supplemented by additional subject matter experts. This solicitation is seeking nominations for the additional experts. The CASAC is a Federal advisory committee chartered under the Federal Advisory Committee Act (FACA), as amended, 5 U.S.C., App. The CASAC Lead Review Panel will comply with the provisions of FACA and all appropriate SAB Staff Office procedural policies.

The CAA Act requires periodic review and, if appropriate, revision of the criteria and NAAQS for lead. EPA's Air Quality Criteria Document (AQCD) for Lead was first published in 1978, and revised in 1986. An addendum was published in 1986, and a Supplement to the Lead AQCD was published in 1990. The latter document evaluated lead effects on cardiovascular endpoints, pregnancy, and early postnatal exposures. The 1990 supplement did not lead to revision of the primary and secondary lead standards issued in 1978. The National Center for Environmental Assessment, Research Triangle Park, NC (NCEA-RTP), in EPA's Office of Research and Development, released a draft Project Work Plan for Revised Air Quality Criteria for Lead in January 2005. The chartered CASAC conducted a consultation on this draft work plan on March 28, 2005. The Agency is scheduled to release the First External Review Draft AQCD for Lead (First Draft Lead AQCD) in January 2006. At that time, the Agency will also invite public comments on the First Draft Lead AQCD. The Agency has asked CASAC to peer-review the First Draft Lead AQCD at a public meeting in May 2006.

The SAB Staff Office is announcing the formation of the CASAC Lead Review Panel to review the criteria and the Agency's Staff Paper for Lead. The Staff Paper for Lead evaluates policy implications of the key scientific and technical information contained in the AQCD for Lead. As such, the staff paper bridges the gap between the science in the Lead AQCD, and the public health and welfare policy judgments that the EPA Administrator must also consider when reviewing the Lead National Ambient Air Quality Standard (NAAQS).

The SAB Staff Office is soliciting nominations for qualified scientists to serve on the CASAC Lead Review Panel. The CASAC Lead Review Panel will operate for two to four years, and will be provided with a separate charge for each review or project.

Technical Contact

Any questions concerning the AQCD for Lead should be directed to Dr. Robert Elias, NCEA-RTP, at phone: (919) 541-4167; or e-mail: NCEA-RTP expects to release and post the First Draft Lead AQCD on the NCEA Web site at:​ncea/​ for external review in January 2006.

Please note that even negative responsive information (e.g., no recent grant or contract funding) should be indicated on the biosketch (by “N/A” or “None”). Incomplete biosketches will not be considered. The EPA SAB Staff Office will acknowledge receipt of nominations.

The credentials of nominees received in reply to this notice will be compared to the specific expertise sought for the CASAC Lead Review Panel. Qualified nominees will be included in a smaller subset (known as the “Short List”). The Short List will be posted on the SAB Web site at:​sab, and will include, for each candidate, the nominee's name and their biosketch. Public comments will be accepted for 21 calendar days on the Short List. During this comment period, the public will be requested to provide relevant information or other documentation on nominees that the SAB Staff Office should consider in evaluating candidates. Panelists will be selected from the Short List.

For the EPA SAB Staff Office, a balanced subcommittee or review panel includes candidates who possess the necessary domains of knowledge, the relevant scientific perspectives (which, among other factors, can be influenced by work history and affiliation), and the collective breadth of experience to adequately address the charge. In establishing the final Panel, the SAB Staff Office will consider public responses to the Short List, information provided by candidates, and background information independently-gathered by the SAB Staff Office on each candidate (e.g., financial disclosure information and computer searches to evaluate a nominee's prior involvement with the topic under review). Specific criteria to be used in evaluating Short List candidates for Panel membership include: (a) Scientific and/or technical expertise, knowledge, and experience (primary factors); (b) availability and willingness to serve; (c) absence of financial conflicts of interest; (d) absence of an appearance of a lack of impartiality; and (e) skills working in committees, subcommittees and advisory panels; and, for the Panel as a whole, (f) diversity of, and balance among, scientific expertise, viewpoints, etc.

Prospective candidates will also be required to fill-out the “Confidential Financial Disclosure Form for Special Government Employees Serving on Federal Advisory Committees at the U.S. Environmental Protection Agency” (EPA Form 3110-48). This confidential form allows Government officials to determine whether there is a statutory conflict between that person's public responsibilities (which includes membership on an EPA Federal advisory committee) and private interests and activities, or the appearance of a lack of impartiality, as defined by Federal regulation. The form may be viewed and downloaded from the following URL address:​sab/​sge_​course/​pdf_​sge/​epaform3110_​48.pdf.

The approved policy under which the EPA SAB Office selects subcommittees and review panels is described in the following document: Overview of the Panel Formation Process at the Environmental Protection Agency Science Advisory Board (EPA-SAB-EC-02-010), which is posted on the SAB Web site at:​sab/​pdf/​ec02010.pdf.
