NO2 NAAQS Review: Policy Assessment

Description:

The Policy Assessment is intended to help "bridge the gap" between the scientific information and assessment and the judgements required of the EPA Administrator in determining whether, and if so how, it is appropriate to revise the NAAQS for NO2. The Policy Assessment will reflect EPA staff's views regarding the broadest array of options supported by the available information. The Policy Assessment will consider the available scientific evidence presented in the Integrated Science Assessment (ISA) and the Risk/Exposure Analysis (REA), together with related limitations and uncertainties, and will focus on the basic elements of an air quality standard: indicator, averaging time, form, and level. These elements, which serve to define each NAAQS, will be considered collectively in evaluating the public health and welfare protection afforded by the standard(s). Following the review of the first draft of this document (NO2 NAAQS Policy Assessment - 1st Draft), as needed, a second draft will be produced and also provided to CASAC for review as well as made available to the public for review and comment. A final draft document will be produced after considering CASAC and public comments. All documents will be made publicly available.
