Abstract
EPA is taking final action to approve a State Implementation Plan (SIP) revision submitted by the State of Indiana to allow the State to discontinue the vehicle inspection and maintenance (I/M) program in Clark and Floyd Counties, IN, the Indiana portion of the Louisville (IN-KY) 1997 8-hour ozone area. The revision specifically provides that I/M program regulations be removed from the active control measures portion of the SIP. The regulations will remain in the contingency measures portion of the Clark and Floyd Counties ozone maintenance plans. EPA is approving Indiana's request because the State has demonstrated that discontinuing the I/M program in Clark and Floyd Counties will not interfere with the attainment and maintenance of the 8-hour ozone National Ambient Air Quality Standard (NAAQS) or with the attainment and maintenance of other air quality standards and requirements of the Clean Air Act (CAA).
