Approval and Promulgation of Air Quality Implementation Plans; District of Columbia: Enhanced Motor Vehicle Inspection and Maintenance Program

Zusammenfassung

EPA is proposing disapproval of a State Implementation Plan (SIP) revision submitted by the District of Columbia on July 13, 1995 and supplemented on March 27, 1996. This revision amends the District's motor vehicle inspection and maintenance (I/M) program required to be enhanced under the Clean Air Act. The intended effect of this action is to propose disapproval of the enhanced I/M program proposed by the District. This action is being taken under section 348 of the National Highway System Designation Act of 1995 (NHSDA) and section 110 of the Clean Air Act (CAA). EPA is proposing disapproval of the District's enhanced I/M SIP revision because it is deficient with respect to the requirements of the CAA and EPA's enhanced I/M program regulatory requirements. In taking action under section 110 of the CAA it is appropriate to propose disapproval of the District's enhanced I/M submittal because there are so many deficiencies with respect to CAA statutory and regulatory requirements described in more detail below.
