Abstract
EPA is approving revisions to the oxides of nitrogen (NO<INF>X</INF>) budget trading program submitted by Indiana on June 26, 2003, and August 4, 2003. These changes revise Indiana's NO<INF>X</INF> State Implementation Plan (SIP) and NO<INF>X</INF> budget approved by EPA on November 8, 2001. The most significant change adds 17 units from three sources to the NO<INF>X</INF> trading portion of the Indiana plan. The plan revision also includes: A compliance date change to accommodate revised deadlines under the NO<INF>X</INF> SIP call; a revised definition of "energy efficiency project" to include anaerobic digestion systems; the addition of formulas to describe an energy efficiency and renewable energy "set aside"; and minor wording changes and correction of typographical errors. These changes are consistent with Indiana's previously approved "Phase I budget."
