Approval and Promulgation of Implementation Plans Georgia: Enhanced Inspection and Maintenance Plan

EPA is approving two revisions to the Georgia State Implementation Plan (SIP), submitted by the Georgia Department of Natural Resources (GA DNR), through the Georgia Environmental Protection Division (GA EPD), on July 25, 2006, and January 25, 2007. The revisions include modifications to Georgia's Air Quality Rules found at Chapter 391-3-20, pertaining to rules for Enhanced Inspection and Maintenance (I/M). Enhanced I/M was required for 1-hour nonattainment areas classified as serious and above, under the CAA as amended in 1990. The I/M program is a way to ensure that vehicles are maintained properly and verify that the emission control system is operating correctly, in order to reduce vehicle-related emissions. This action is being taken pursuant to section 110 of the Clean Air Act (CAA).
