In this final rule, the Environmental Protection Agency (EPA) has determined that the Atlanta metro area is not a federal reformulated gasoline (RFG) covered area and, therefore, that there is no requirement to use RFG in the Atlanta area. Atlanta is the only RFG covered area formerly classified as a severe ozone nonattainment area under the 1-hour ozone National Ambient Air Quality Standard that was redesignated to attainment for that standard before its revocation, and at a time when it was designated as nonattainment for the 8-hour ozone standard with a classification less than severe. EPA has determined that the statute is ambiguous as to whether RFG is required in this situation. EPA believes that the comprehensive planning conducted by the State through the SIP process, the array of regulatory tools at the State's disposal, and the current limited emissions benefits of RFG in Atlanta as compared to the current state fuel (as explained elsewhere in the document) indicate that it would be appropriate to interpret the relevant statutory language to not require RFG use in Atlanta.
