EPA is taking direct final action to approve the ozone 2002 base year emissions inventory portion of the state implementation plan (SIP) revision submitted by the State of North Carolina November 12, 2009. The emissions inventory is part of the Charlotte-Gastonia-Rock Hill, North Carolina ozone attainment demonstration that was submitted for the 1997 8-hour ozone national ambient air quality standards (NAAQS). The Charlotte-Gastonia-Rock Hill, North Carolina-South Carolina 1997 8-hour ozone nonattainment area (hereafter referred to as the "bi-state Charlotte Area") is comprised of Cabarrus, Gaston, Lincoln, Mecklenburg, Rowan, Union and a portion of Iredell (Davidson and Coddle Creek Townships) Counties in North Carolina; and a portion of York County in South Carolina. This action is being taken pursuant to section 110 of the Clean Air Act (CAA or Act). EPA will take action on the South Carolina submission for the ozone 2002 base year emissions inventory for its portion of the bi-state Charlotte Area in a separate action.
