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. The CASAC provides 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 chartered under the Federal Advisory Committee Act (FACA), as amended, 5 U.S.C., App. The CASAC Lead Review Panel consists of the seven CASAC members supplemented by subject-matter-experts. The CASAC Lead Review Panel provides advice and recommendations to EPA concerning lead in ambient air. The Panel complies with the provisions of FACA and all appropriate SAB Staff Office procedural policies.

Section 109(d)(1) of the CAA requires that the Agency periodically review and revise, as appropriate, the air quality criteria and the national ambient air quality standards (NAAQS) for the six “criteria” air pollutants, including Lead. On September 30, 2006, 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 a document, Air Quality Criteria for Lead (EPA/600/R-05/144aC-bC). This final 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. The CASAC's most-recent letter to the Administrator concerning the draft Lead AQCD (EPA-CASAC-06-010, dated September 6, 2006) is posted on the SAB Web site at​sab/​pdf/​casac-06-010.pdf. Detailed summary information on the Final AQCD for Lead is contained in a previous EPA Federal Register notice (71 FR 57508, September 29, 2006).

In December 2006, EPA's Office of Air Quality Planning and Standards (OAQPS), within the Office of Air and Radiation (OAR), released the 1st Draft Lead Staff Paper and the Draft Lead Exposure and Risk Assessments document as part of its review of the Lead NAAQS. The purpose of the 1st Draft Lead Staff Paper is to evaluate the policy implications of the key scientific Start Printed Page 1988and technical information contained in the Agency's Final AQCD for Lead and to identify critical elements that EPA staff believes should be considered in its review of the Lead NAAQS. The Lead Staff Paper is intended to “bridge the gap” between the scientific review contained in the Lead AQCD and the public health and welfare policy judgments required of the EPA Administrator in reviewing the Lead NAAQS. The Draft Lead Exposure and Risk Assessments technical support document describes the methodology and presents the results of the pilot phase human exposure and health risk assessments and ecological risk assessments for a number of case studies.

Technical Contacts: Any questions concerning the Agency's 1st Draft Lead Staff Paper should be directed to Dr. Deirdre Murphy, OAQPS, at phone: 919-541-0729, or e-mail: Any questions about the human exposure and health risk analyses in the Draft Lead Exposure and Risk Assessments technical support document can be directed to Dr. Zachary Pekar, OAQPS, at phone: 919-541-3704, or e-mail:; while questions about the environmental assessment can be directed to Ms. Ginger Tennant, OAQPS, at phone: 919-541-4072, or e-mail:
