Federal Implementation Plans for Iowa, Michigan, Missouri, Oklahoma, and Wisconsin and Determination for Kansas Regarding Interstate Transport of Ozone

Résumé

In this final rule, EPA is concluding that emissions from Iowa, Kansas, Michigan, Missouri, Oklahoma, and Wisconsin significantly contribute to downwind nonattainment or interfere with maintenance of the 1997 ozone National Ambient Air Quality Standards (NAAQS)in other states. Each of these states except Oklahoma is already included in the annual NO X program that was finalized in July 2011. However, this rule does not affect that program. EPA is finalizing Federal Implementation Plans (FIPs) to address the emissions in each of these states except for Kansas, for which EPA is not finalizing a FIP at this time. The FIPs apply the requirements of the ozone season NO X program in the Transport Rule (Federal Implementation Plans to Reduce Interstate Transport of Fine Particulate Matter and Ozone in 27 States; Correction of SIP Approvals for 22 States) to sources in Iowa, Michigan, Missouri, Oklahoma, and Wisconsin. In addition, this action finalizes the budgets; associated variability limits, new unit set-asides, and Indian country new unit set-asides; and unit-level allowance allocations for each state under the FIPs.
