EPA is taking direct final action to approve revisions to the North Carolina State Implementation Plan (SIP). On February 16, 2005, the North Carolina Department of Environment and Natural Resources submitted revisions to the Mecklenburg County Air Pollution Control Ordinance (MCAPCO) to be incorporated into the Mecklenburg County portion of the North Carolina SIP. The revisions include changes to MCAPCO 2.0902, "Applicability," and 2.0933, "Petroleum Liquid Storage in External Floating Roof Tanks." These changes were made to maintain consistency with State and federal regulations, and are part of Mecklenburg County's strategy to attain and maintain the 8-hour ozone National Ambient Air Quality Standard (NAAQS), by reducing precursors to ozone. EPA is approving this SIP revision pursuant to section 110 of the Clean Air Act (CAA).
