The Environmental Protection Agency (EPA) is proposing to approve a submission from the State of Indiana as a state implementation plan (SIP) revision in according with the Clean Air Act (CAA). On April 25, 2019, the state submitted its 1997 8-hour ozone national ambient air quality standards (NAAQS or standard) Limited Maintenance Plan (LMP) for the following Indiana areas:] Evansville, Fort Wayne, Greene County, Jackson County, Muncie, and Terre Haute. EPA is proposing to approve the LMPs for these areas because they provide for the maintenance of the 1997 8-hour ozone NAAQS through the end of the second 10-year portion of the maintenance period. The effect of this action would be to make federally enforceable certain commitments related to maintenance of the 1997 8-hour ozone NAAQS in these areas as part of the Indiana SIP.
