Abstract: As required under the Clean Air Act, the periodic review of the national ambient air quality standards (NAAQS) for particulate matter (PM) is now underway. EPA is now releasing a preliminary draft PM Staff Paper for public and peer review. Chapter 4 of the preliminary draft Staff Paper includes a discussion of proposed future analyses on health risk assessment. The draft Risk Analysis Scoping Plan describes, in more detail, EPA's plans and approach for conducting PM health risk analyses that will be summarized and discussed in the next draft of the Staff Paper. This file contains the draft Scoping Plan, which along with the preliminary draft Staff Paper, is being released for public and peer review.
