Status of CAA 110(a)(2)(D)(i)(I) SIPs Supplemental Rule Technical Support Document for the Supplemental Notice of Final Rulemaking

This document describes, for the states of Iowa, Kansas, Michigan, Missouri, Oklahoma and Wisconsin, the status of each Clean Air Act (CAA or Act) 110(a)(2)(D)(i)(I) state implementation plan (SIP) for the 1997 ozone NAAQS. It describes any findings of failure to submit 110(a)(2)(D)(i)(I) SIPs for the 1997 ozone NAAQS made by EPA for these states, and any actions taken by EPA with respect to 110(a)(2)(D)(i)(I) SIP submissions for the 1997 ozone NAAQS received from these states. The facts presented in this TSD support EPA’s conclusion that it has a legal obligation to promulgate each of the FIPs promulgated in this rule. Note that EPA is not promulgating a FIP for Kansas. Nonetheless, for completeness, this document includes an explanation of the status of the Kansas 110(a)(2)(D)(i)(I) SIP for the 1997 ozone NAAQS.
