This document is part of the Environmental Protections Agency's (EPA's) review of the National Ambient Air Quality Standards (NAAQS) for lead. Based on the information contained in the Agency's Air Quality Criteria Document for Lead (October 2006), this draft Staff Paper includes assessments and preliminary analyses related to: 1. air quality characterization, 2. integration and evaluation of health information, 3. human exposure analysis and health risk assessment, and 4. evaluation and analysis of information on vegetation damage and other welfare effects. This initial draft document does not include any conclusions or recommendations with regard to potential retention or revision of the lead NAAQS. To date, the lead NAAQS review has followed our historic approach to reviewing NAAQS, including issuance of a criteria document and a first draft staff paper. The Agency is now moving forward to implement a new, more efficient process for conducting NAAQS reviews (http://www.epa.gov/ttn/naaqs/). EPA intends to transition to that new process during the course of the lead NAAQS review.
