The Environmental Protection Agency (EPA) is approving under the Clean Air Act (CAA) a request from the Indiana Department of Environmental Management (IDEM) to revise the Indiana State Implementation Plan (SIP) to incorporate the following: A new rule concerning nitrogen oxide (NO<INF>X</INF>) emissions for the ozone season from Electric Generating Units (EGUs) and large non-EGUs; revisions concerning NO<INF>X</INF> emission rate limits for specific source categories; the repeal of the NO<INF>X</INF> Budget Trading Program; and the repeal of the Clean Air Interstate Rule (CAIR) NO<INF>X</INF> ozone season trading program. This SIP revision will ensure continued compliance by EGUs and large non-EGUs with the requirements of the NO<INF>X</INF> SIP Call.
