This planning document is intended to provide enough specificity to facilitate consultation with CASAC, as well as for public review, in order to obtain advice on the overall scope, approaches, and key issues in advance of the conduct of the risk and exposure analyses and presentation of results in the first draft REA. NCEA has compiled and assessed the latest available policy-relevant science available to produce a first draft of the ISA and related Annexes (US EPA, 2008b). The first draft ISA has been reviewed by staff and used in the development of the approaches described below. This includes information on atmospheric chemistry, source emissions, air quality, human exposure, and related health effects. CASAC consultation on this planning document coincides with its review of the first draft ISA. CASAC and public comments on this document will be taken into consideration in the development of the first draft REA, the preparation of which will coincide and draw from the second draft ISA. The second draft REA will draw on the final ISA and will reflect consideration of CASAC and public comments on the first draft REA. The final REA will reflect consideration of CASAC and public comments on the second draft REA. The final ISA and final REA will inform the policy assessment and rulemaking steps that will lead to a final decision on the PM NAAQS.
