Abstract
EPA announced that the First External Review Draft of the Integrated Science Assessment (ISA) for Lead (Pb) was made available for independent peer review and public review. This draft ISA represents a concise synthesis and evaluation of the most policy-relevant science and will ultimately provide the scientific bases for EPA’s decision regarding whether the current standards for Pb sufficiently protect public health and the environment.EPA released this draft document to seek review by the Clean Air Scientific Advisory Committee (CASAC) and the public (meeting date and location to be specified in a separate Federal Register notice). The draft document does not represent, and should not be construed to represent, any final EPA policy, viewpoint, or determination. EPA will consider any timely public comments submitted when revising the document. Lead (Pb) is one of six principal (or criteria) pollutants for which EPA has established NAAQS. Periodically, EPA reviews the scientific basis for these standards by preparing an Integrated Science Assessment (ISA) (formerly called an Air Quality Criteria Document). The ISA, in conjunction with additional technical and policy assessments, provide the scientific basis for EPA decisions on the adequacy of the current NAAQS and the appropriateness of possible alternative standards. The Clean Air Scientific Advisory Committee (CASAC), an independent science advisory committee whose existence and whose review and advisory functions are mandated by Section 109 (d) (2) of the Clean Air Act, is charged with (among other things) independent scientific review of EPA's air quality criteria.
Impact/Purpose
Lead (Pb) is one of six principal (or criteria) pollutants for which EPA has established NAAQS.Status
The first external review draft ISA for Pb will be discussed at a public meeting for review by CASAC, and public comments received will be provided to the CASAC review panel. A future Federal Register notice will inform the public of the exact date and time of that CASAC meeting. In revising and finalizing the ISA, EPA will take into account CASAC advice and recommendations as well as public comments. The final ISA is scheduled for release in July 2012.Citation
