Annual emissions reporting (i.e., emissions statements) and a base year emissions inventory are required for all ozone nonattainment areas. The Area is comprised of the entire county of Mecklenburg and a portion of Cabarrus, Gaston, Lincoln, Rowan, Union Counties in North Carolina and a portion of York County in South Carolina. EPA has published proposed and direct final actions on the emissions inventory and emissions statements requirements for the North Carolina portion of the bi-state Charlotte Area in separate rulemaking documents.
