| Abstract |
This Policy Assessment (PA) has been prepared by staff in the Environmental Protection Agencys (EPA) Office of Air Quality Planning and Standards (OAQPS) as part of the Agencys ongoing review of the primary (health-based) and secondary (welfare-based) national ambient air quality standards (NAAQS) for lead (Pb). It presents analyses and staff conclusions regarding the policy implications of the key scientific and technical information that informs this review. The PA is intended to bridge the gap between the relevant scientific evidence and technical information and the judgments required of the EPA Administrator in determining whether to retain or revise the current standards. Development of the PA is also intended to facilitate advice and recommendations on the standards to the Administrator from an independent scientific review committee, the Clean Air Scientific Advisory Committee (CASAC), as provided for in the Clean Air Act (CAA). Staff analyses in this PA are based on the scientific assessment presented in the Integrated Science Assessment for Lead (ISA) prepared for this review by the EPAs Office of Research and Development (ORD) as well as scientific and technical assessments from prior Pb NAAQS reviews. Such assessments include quantitative human health and ecological risk and exposure assessments (REAs) developed in the last review as new health and ecological REAs were not warranted based on staffs and CASACs consideration of the evidence newly available in this review with regard to risk and exposure assessment. For the purpose of review of the NAAQS in considering the scientific evidence and other technical information available in this review, emphasis is given to consideration of the extent to which the evidence newly available since the last review alters conclusions drawn in the last review with regard to health and welfare effects of Pb, the exposure levels at which they occur and the associated at-risk populations and ecological receptors or ecosystems. |
