SUPPLEMENTARY INFORMATION:

I. Information about the Project/Document

Section 108(a) of the Clean Air Act directs the Administrator to identify certain pollutants that “may reasonably be anticipated to endanger public health and welfare” and to issue air quality criteria for them. These air quality criteria are 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* * *.” Under section 109 of the Act, EPA is then to establish National Ambient Air Quality Standards (NAAQS) for each pollutant for which EPA has issued criteria. Section 109(d) of the Act requires subsequent 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 and welfare. EPA is also to revise the NAAQS, if appropriate, based on the revised criteria.

Lead is one of six “criteria” pollutants for which EPA has established air quality criteria and NAAQS. On November 9, 2004 (69 FR 64926), EPA formally initiated its current review of the criteria and NAAQS for lead, requesting the submission of recent scientific information on specified topics. A draft of EPA's “Project Work Plan for Revised Air Quality Criteria for Lead” (NCEA-R-1465) was released on January 7, 2005, for public comment (70 FR 1439) and was discussed by the Clean Air Scientific Advisory Committee (CASAC) via a publicly accessible March 28, 2005, teleconference consultation (70 FR Start Printed Page 4315511629). On July 15, 2005 (70 FR 41007), several workshops were announced to discuss, with invited recognized scientific experts, initial draft materials that dealt with various lead-related issues being addressed in the draft AQCD for lead. These workshops were held August 4-5, 16-18, and 17-19, 2005. The first external review draft of the Air Quality Criteria for Lead, EPA/600/R-05/144aA-bA, was announced in the Federal Register on December 2, 2005 (70 FR 72300). The CASAC Lead Review Panel reviewed the first external review draft at a public meeting on February 28 and March 1, 2006.

Release of the second external review draft of the Air Quality Criteria for Lead, EPA/600/R-05/144aB-bB, was announced in the Federal Register on May 19, 2006 (71 FR 29152). The CASAC Lead Review Panel reviewed the second external review draft at a public meeting on June 28-29, 2006. EPA is now releasing revised Integrative Synthesis and Executive Summary chapters for public and CASAC review. EPA has considered the comments of the CASAC review panel and of the public in preparing both the Second External Review Draft of the Air Quality Criteria for Lead and these revised Integrative Synthesis and Executive Summary chapters.

After the end of the comment period on the revised Integrative Synthesis and Executive Summary chapters for the Air Quality Criteria for Lead, Second External Review Draft, EPA will present the draft at a public meeting for review by CASAC. Public comments received will be provided to the CASAC review panel. There will be a Federal Register notice to inform the public of the exact date and time of that CASAC meeting.
