The EPA is approving revisions to the State Implementation Plan (SIP) submitted by the Florida Department of Environmental Protection (FDEP) on December 20, 2002. This SIP revision satisfies the requirement of the Clean Air Act (CAA) for the second 10-year update for the Southeast Florida area (Dade, Broward, and Palm Beach Counties) 1-hour ozone maintenance plan. For transportation purposes, EPA is also finalizing its adequacy determination of the new Motor Vehicle Emissions Budgets (MVEBs) for the year 2015. EPA has determined that the MVEBs for the year 2015 contained in this SIP revision are adequate for transportation conformity purposes.
