## Abstract

Previously EPA published a proposed rulemaking (December 30, 1998, 63 FR 71807) to conditionally approve the State of Louisiana's State Implementation Plan (SIP) revision concerning a low-enhanced motor vehicle inspection and maintenance (I/M) program under section 110 of the Clean Air Act (the Act) as amended in 1990. Based on the proposed approval, EPA is making an interim final determination by this action, that the State has more likely than not cured the deficiencies prompting the original disapproval (November 19, 1997, 62 FR 61633) of the Louisiana enhanced I/M SIP revision. This action will defer the future application of the offset sanction and the highway sanction. Although this action is effective upon signature, EPA will take comment on this interim final determination. The EPA will publish a final action taking into consideration any comments received on this interim final action.
