## Abstract

EPA is taking final action to approve a source-specific State Implementation Plan (SIP) revision submitted to EPA by the Commonwealth of Kentucky, through the Kentucky Division for Air Quality (KDAQ) on April 25, 2013, for the purpose of exempting an Enterprise Holdings, Inc., facility from the Clean Air Act (CAA or Act) Stage II vapor control requirements. The subject Enterprise Holdings, Inc., facility is currently being constructed at the Cincinnati/Northern Kentucky International Airport in Boone County, Kentucky. EPA's approval of this revision to Kentucky's SIP is based on the December 12, 2006, EPA policy memorandum from Stephen D. Page, entitled "Removal of Stage II Vapor Recovery in Situations Where Widespread Use of Onboard Refueling Vapor Recovery is Demonstrated." This action is being taken pursuant to the CAA.
