Abstract
The Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision submitted by the Illinois Environmental Protection Agency on November 29, 2012, concerning the state's vehicle inspection and maintenance (I/M) program in the Chicago and Metro-East St. Louis ozone nonattainment areas in Illinois. The revision amends I/M program requirements in the active control measures portion of the ozone SIP to reflect changes that have been implemented at the state level since EPA fully approved the I/M program on February 22, 1999. The submittal also includes a demonstration under section 110(l) of the Clean Air Act (CAA) addressing lost emission reductions associated with the program changes.
