Abstract
The EPA is approving Indiana's oxides of nitrogen (NO<INF>X</INF>) rules which satisfy the requirements of EPA's NO<INF>X</INF> SIP Call Phase II Rule (the Phase II Rule). EPA is approving these regulations based on Indiana's demonstration that they will result in the achievement of the Phase II budget through source compliance with rules affecting stationary internal combustion (IC) engines which are identified in the NO<INF>X</INF> plan submittal. Limiting NO<INF>X</INF> emissions from IC engines will enable the State to meet the Phase II incremental difference of 4,244 tons during the ozone season, thereby improving air quality and protecting the health of Indiana citizens. EPA is also approving other changes to Indiana's NO<INF>X</INF> rules. These are minor clerical corrections and changes in definitions made by Indiana to conform to the revisions made by EPA in the Phase II Rule.
