## Abstract

EPA is approving a request submitted by the Illinois Environmental Protection Agency (Illinois EPA) on October 23, 2007, to revise the Illinois State Implementation Plan (SIP). The State has submitted revisions to 35 Illinois Administrative Code (Ill. Adm. Code) parts 211 and 217. The submitted revisions are final and adopted in the Ill. Adm. Code, and pertain to definitions and general provisions, and control of Nitrogen Oxides (NO<INF>X</INF>). The rules satisfy the requirements of EPA's NO<INF>X</INF> SIP Call Phase II Rule (the Phase II Rule). We are approving these regulations based on Illinois' demonstration that the State will meet the emissions targets set forth in the Phase II Rule through reductions from stationary internal combustion (IC) engines and turbines which are identified in the NO<INF>X</INF> plan submittal. Limiting NO<INF>X</INF> emissions from IC engines and turbines will enable the State to meet the 7,055 ton reduction requirement contained in the Phase II Rule, thereby improving air quality and protecting the health of Illinois citizens.
