The Environmental Protection Agency (EPA) is taking final action to approve changes to the Georgia State Implementation Plan (SIP) to revise the emission reduction credits (ERC) regulation. EPA is approving portions of the SIP revision submitted by the State of Georgia, through the Georgia Department of Natural Resources' Environmental Protection Division (GA EPD) on September 15, 2008. The revision expands the eligibility for sources in Barrow County that can participate in the ERC Program, adds a provision for reevaluation of the Certificates of ERC, changes the administrative fees, and eliminates an exemption for certain types of ERCs. This action is being taken pursuant to the Clean Air Act (CAA or Act).
