SUPPLEMENTARY INFORMATION: Section 108 (a) of the Clean Air Act directs 
the Administrator to identify certain pollutants which ``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. One of the next steps in this process 
was to prepare a project work plan for revision of the existing ``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. Accordingly, 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 11629). 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. EPA considered the comments of the CASAC review panel 
and of the public in drafting this ``Air Quality Criteria for Lead, 
Second External Review Draft.''
    After the end of the comment period on the ``Air Quality Criteria 
for Lead, Second External Review Draft,'' the CASAC review panel will 
review the draft at a public meeting. 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.
