The Environmental Protection Agency (EPA) is proposing to approve a request from Wisconsin to revise the designation for the Sheboygan nonattainment area for the 1997 primary and secondary ozone National Ambient Air Quality Standards (NAAQS) and the 2008 primary and secondary ozone NAAQS, by splitting the existing area into two distinct nonattainment areas that together cover the identical geographic area of the existing nonattainment area. This revised designation is supported by air quality data, emissions and emissions-related data, meteorology, geography/topography, and jurisdictional boundaries. Both areas would retain their nonattainment designation and Moderate classification. In this action, EPA is also proposing to make a clean data determination for one of the two separate areas for the 2008 ozone NAAQS.
