## Abstract

EPA is approving three revisions to the State Implementation Plan (SIP) for the state of Texas. These revisions make changes to the Texas Low-Emission Diesel (TXLED) Fuel program. The revisions establish a replicable procedure for the State to approve Alternative Emission Reduction Plans (AERPs), extend the date of state approvals, and bring marine diesel fuels under the TXLED program. The revisions also refine and clarify testing requirements. The changes being approved will contribute to the reduction of oxides of nitrogen (NO<INF>X</INF> ) in the covered area. EPA is approving the revisions pursuant to Clean Air Act (CAA) section 211 and the Energy Policy Act (EPAct).
