## Abstract

The EPA is approving a revision to the Louisiana State Implementation Plan (SIP) that contains the transportation conformity rule. The conformity rules assure that in air quality nonattainment or maintenance areas, projected emissions from transportation plans and projects stay within the motor vehicle emissions ceiling in the SIP. The transportation conformity SIP revision enables the State to implement and enforce the Federal transportation conformity requirements at the State level. The EPA's approval action streamlines the conformity process and allows direct consultation among agencies at the local levels. The final approval action is limited to Transportation Conformity. The EPA approved the SIP revision sent under conformity of general Federal actions on September 13, 1996 (61 FR 48409). The EPA approves this SIP revision under sections 110(k) and 176 of the Clean Air Act (Act). We have given our rationale for approving this SIP revision in this action.
