QUESTIONS REGARDING THE DESIGNATIONS OF RACINE COUNTY PURSUANT TO THE CLEAN AIR ACT 1. In regard to the 2015 ozone standard, is EPA going to designate Racine County as attainment, unclassifiable, or nonattainment? 2. If Racine County was designated as unclassifiable, at what point in the future would that designation potentially change? What would be the legal process to change the designation? 3. If there was a nonattainment area designation, does EPA agree that the area designated to nonattainment should be limited to the geographic area in which data and science indicate there is a potential to exceed the 2015 standard? a. Given technology that is currently available, does EPA agree, if a portion of Racine County was designated as nonattainment, the boundary should be based on data and science and does not necessarily need to follow features such as jurisdictional boundaries or roadways? 4. Racine does not have a 2014-16 design value because 2014 data is not available. Consequently, does EPA believe there is insufficient information available to make a designation? As such, does EPA have the authority to extend the initial designation of Racine County for one year? If so, when would the extension expire? 5. Governor Walker recommended that Wisconsin be designated as attainment. If EPA made a decision inconsistent with that recommendation, how would EPA reconcile the 120-day notification requirement and the corresponding opportunity for state response? Sierra Club v.
