## Abstract

EPA is approving a state implementation plan (SIP) revision submitted by the Wisconsin Department of Natural Resources on June 7, 2012, concerning the state's vehicle inspection and maintenance (I/M) program in southeast Wisconsin. 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 August 16, 2001. 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.
