Background: 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 Clean Air Act (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 revised draft document, Air Quality Criteria for Lead (First External Review Draft), Volumes I and II (EPA/600/R-05/144aA-bA). This first draft Lead air quality criteria document (AQCD) represented a revision 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 revised 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 the revised draft AQCD for lead is contained in a previous EPA Federal Register notice (70 FR 72300, December 2, 2005).

EPA is soliciting advice and recommendations from the CASAC by means of a peer review of the revised draft Lead AQCD. 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. Earlier this year, the SAB Staff Office established a CASAC Lead Review Panel to provide EPA with advice and recommendations concerning lead in ambient air. The Panel complies with the provisions of FACA and all appropriate SAB Staff Office procedural policies. Start Printed Page 34130

This meeting is a continuation of the CASAC Lead Review Panel's peer review of the current draft Lead AQCD. The Lead 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 addition, in conjunction with its preparation of the Lead Staff Paper, EPA's Office of Air Quality Planning and Standards (OAQPS), within the Office of Air and Radiation (OAR), on May 31, 2006 released a draft Analysis Plan for Human Health and Ecological Risk Assessment for the Review of the Lead National Ambient Air Quality Standards. The purpose of this analysis plan is to outline the scope, approaches, and methods that Agency staff are planning to use for the human health and ecological risk assessments for lead. This plan also highlights key issues in the estimation of human health and ecological exposure and risks posed by lead under existing air quality levels (“as is” exposures and health risks). Furthermore, this analysis plan is intended to facilitate consultation with the CASAC, as well as public review, for the purpose of obtaining advice on the overall scope, approaches, and key issues in advance of the completion of such analyses and presentation of results in the first draft Lead Staff Paper.
