Summary

The Environmental Protection Agency (EPA) is proposing to disapprove elements of State Implementation Plan (SIP) submissions from Indiana and Ohio regarding the infrastructure requirements of section 110 of the Clean Air Act (CAA) for the 2008 ozone National Ambient Air Quality Standards (NAAQS), and to partially approve and partially disapprove elements of the SIP submission from Wisconsin addressing the same requirements. The infrastructure requirements are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the CAA. This action pertains specifically to infrastructure requirements concerning interstate transport provisions. Ohio, Indiana, and Wisconsin made SIP submissions that, among other things, certified that their existing SIPs were sufficient to meet the interstate transport infrastructure SIP requirements for the 2008 ozone NAAQS. EPA is proposing to disapprove portions of submissions from Indiana and Ohio, and to partially approve and partially disapprove a portion of Wisconsin's submission addressing these requirements.
