Background: The CASAC, which is comprised of seven members appointed by the EPA Administrator, 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, in part to provide advice, information and recommendations on the scientific and technical aspects of issues related to air quality criteria and NAAQS under sections 108 and 109 of the Act. 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, which consists of the seven CASAC members supplemented by subject-matter-expert Panelists, provides EPA with advice and recommendations concerning lead in ambient air. The CASAC Panel complies with the provisions of FACA and all appropriate SAB Staff Office procedural policies.

EPA is in the process of updating, and revising where appropriate, the air quality criteria document (AQCD) for Lead. Section 109(d)(1) of the CAA requires that EPA carry out a periodic review and revision, as appropriate, of the air quality criteria and the national ambient air quality standards (NAAQS) for the six “criteria” air pollutants, including Lead. On December 1, 2005, EPA's National Center for Environmental Assessment National, Research Triangle Park (NCEA-RTP), within the Agency's Office of Research and Development (ORD), made available for public review and comment a first draft document, Air Quality Criteria for Lead, Volumes I and II (EPA/600/R-05/144aA-bA). This AQCD represented an update to the previous EPA document, Air Quality Criteria for Lead, EPA-600/8-83/028aF-dF (published in June 1986) and an associated supplement (EPA-600/8-89/049F) published in 1990. Under CAA sections 108 and 109, the purpose of the updated AQCD is to provide an assessment of the latest scientific information on the effects of ambient Lead on the public health and welfare, for use in EPA's current review of the NAAQS for Lead. Detailed summary information on this first draft AQCD for lead is contained in a previous EPA Federal Register notice (70 FR 72300, December 2, 2005).

The CASAC Panel met in a public meeting on February 28 and March 1, 2006 to conduct its initial peer review of the first draft Lead AQCD. The report from that meeting, dated April 26, 2006, is posted on the SAB Web site at:​sab/​pdf/​casac-06-005.pdf. In May 2006, NCEA-RTP released a second draft Lead AQCD (EPA/600/R-05/144aB-bB) for public review and comment. The CASAC Panel met in a public meeting on June 28 and 29, 2006 to conduct a peer review of the second draft Lead AQCD. The CASAC's report from that meeting is still under development and will be posted on the SAB Web site at:​sab/​fiscal06.htm upon completion. At its June 2006 public meeting, the CASAC Panel requested an opportunity to provide additional review of the revised draft Executive Summary and Chapter 7 (Integrative Synthesis) of the AQCD. The purpose of this teleconference is for the CASAC Panel to conduct this review. Start Printed Page 40517
