## Abstract

EPA is taking direct final action to approve a revision to the Virginia State Implementation Plan (SIP). The revision pertains to a Transcontinental Gas Pipe Line Corporation (Transco) operating permit that EPA approved into the Virginia SIP to meet nitrogen oxides (NO<INF>X</INF>) reduction requirements for large stationary internal combustion engines under the NO<INF>X</INF> SIP Call. Transco Station 175 has permanently shut down, and this revision removes the permit from the Virginia SIP. EPA is approving this revision in accordance with the requirements of the Clean Air Act (CAA).
