Description:

On October 1st, 2015, EPA announced that the 8-hour ozone NAAQS was being reduced from the current 70 ppb. While the update to the standard is significant, the more onerous development with regard to ozone impacts is the proposed revision to Appendix W that would require major sources applying for a PSD permit to assess the impacts on ozone formation. EPA now contends that advances in photochemical models such as CAMx and CMAQ, as well as the widespread availability of more powerful computers, have made it feasible to assess the impact of individual sources on the formation of these secondary pollutants. This is a significant change in approach to these pollutants that have long been thought of as regional and handled by addressing the sum of regional and upwind emissions rather than studying the potential contribution of a single facility.
