Approval and Promulgation of Air Quality State Implementation Plans (SIP); Louisiana: Motor Vehicle Inspection and Maintenance (I/M) Program

Resumo

The EPA is proposing conditional approval of a Vehicle Inspection and Maintenance (I/M) Program proposed by the State of Louisiana. This action is taken under section 110 of the Clean Air Act (the Act). This conditional approval is also being proposed under the parallel processing provision of 40 CFR part 51. The EPA is proposing a conditional approval because the SIP revision is lacking certain elements necessary to meet the statutory and regulatory requirements of an enhanced I/M program. To correct the SIP deficiencies, the State must commit by a date certain within one year of final EPA rulemaking on this SIP to: submit a demonstration supporting its claim of 100 percent network effectiveness; submit an effectiveness demonstration of sticker-based enforcement; submit an opinion from the State Attorney General regarding barriers to immediate suspension authority in the Louisiana Constitution; submit an updated interagency agreement between the Louisiana Department of Environmental Quality (LDEQ) and the Department of Public Safety (DPS); make changes to the DPS Official Motor Vehicle Inspection Manual (the Manual) to reflect: changing the weight of light-and heavy-duty vehicles
