This approval expires on August 7, 1998, or earlier if by such earlier date the State has submitted as a SIP revision a demonstration that the carbon monoxide emission reduction credits for the enhanced motor vehicle inspection and maintenance program are appropriate and that the program is otherwise in compliance with the Clean Air Act and EPA takes final action approving that revision, as provided by section 348(c) of the National Highway System Designation Act (Public Law 104-59).
