The State of Louisiana motor vehicle Inspection and Maintenance (I/M) program SIP submittal of August 18, 1995, with later editions, is disapproved based on the failure of the State Legislature to grant legal authority to reauthorize and continuously operate the program until the program is no longer necessary. The Baton Rouge serious ozone nonattainment area is required to have an enhanced I/M program under section 182 of the Clean Air Act (the Act) as amended in 1990. This disapproval initiates the sanction process of section 179(a) of the Act. [62 FR 61634, Nov. 19, 1997; 63 FR 4397, Jan. 29, 1998]
