On November 8, 1993, the State of Florida, through the Florida Department of Environmental Protection (FDEP), submitted a maintenance plan and a request to redesignate the Southeast Florida area from moderate nonattainment to attainment for ozone (O<INF>3). The Southeast Florida O<INF>3 nonattainment area consists of Dade, Broward and Palm Beach Counties. Under the Clean Air Act as amended in 1990 (CAA), designations can be revised if sufficient data are available to warrant such revisions and the CAA redesignation requirements are satisfied. In this action, EPA is approving Florida's request because it meets the maintenance plan and redesignation requirements set forth in the CAA, and EPA is also approving the 1990 base year emission inventory for the Southeast Florida area. The approved maintenance plan will become a federally enforceable part of the State Implementation Plan (SIP) for the Southeast Florida area.
