EPA is amending its regulations to reflect a change in address for EPA's Region 4 office as well as the state agencies for Georgia, Mississippi, North Carolina and local agencies for Forsyth County, Mecklenburg County Land Use & Environmental Services Agency and Western North Carolina Regional Air Quality Agency. The jurisdiction of EPA Region 4 includes the States of Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina and Tennessee. Certain EPA air pollution control regulations requiring submittal of notifications, reports and other documents to the EPA Regional office must also be submitted to the appropriate authorized state or local agency. This technical amendment updates and corrects the addresses for submitting such information to the EPA's Region 4 office as well as the state and local agency offices.
