||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 conducting the UVA and presentation of results in the first draft of the UVA. 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), which we have reviewed and used in the development of the approaches described below. This includes information on atmospheric chemistry, source emissions, air quality, urban visibility conditions, public perception/preference studies and other PM-related welfare 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 UVA, the preparation of which will coincide and draw from the second draft ISA. The second draft UVA will draw on the final ISA and will reflect consideration of CASAC and public comments on the first draft UVA. The final UVA will reflect consideration of CASAC and public comments on the second draft UVA.
