## Abstract

EPA is taking direct final action to approve a revision to the State of Delaware State Implementation Plan (SIP). The revision corrects the definition of the term "Fire-Resistant (interior) Coating" in Delaware's regulation to control volatile organic compound (VOC) emissions from aerospace coatings operations. The correction to the definition makes it consistent with EPA's Control Technique Guideline (CTG) for this VOC source category. EPA is approving this revision to the SIP in accordance with the requirements of the Clean Air Act.
