Abstract

This report describes review and analysis activities which have been undertaken to support the EPA goal of developing technical and policy guidelines for assessing the oxidant air quality impact of highway development under the 3-C planning process. Separate sections discuss somewhat diverse topics, although they are all directed towards oxidant impact assessment. These sections include (1) a review of the techniques and computer models available for estimating mobile source emissions; (2) a brief summary of oxidant formation processes; (3) a discussion of the oxidant modeling activities of this project using the DIFKIN and Gifford-Hanna photochemical models, and (4) a 'test run' of the 109(j) and indirect source review guidelines.
