The EPA is approving a revision to the Florida State Implementation Plan (SIP) submitted on August 14, 1998, with the exception of one state regulation pertaining to triggers. The revision contains the transportation conformity rule pursuant to the Clean Air Act as amended in 1990 (Act), including detailed consultation procedures for implementing the transportation conformity rule. The transportation conformity rule assures that projected emissions from transportation plans, improvement programs and projects in air quality nonattainment or maintenance areas stay within the motor vehicle emissions ceiling contained in the SIP. The transportation conformity SIP revision enables the State to implement and enforce the Federal transportation conformity requirement at the state level. This action streamlines the conformity process to allow direct consultation among agencies at the local level. This final approval action is limited to requirements for transportation conformity.
