Today's action revises the Motor Vehicle Inspection/ Maintenance (I/M) requirements by replacing the I/M rule requirement that the tailpipe portion of the mandatory program evaluation be performed using only an IM240 or equivalent mass-emission transient test with a requirement that states use a sound evaluation methodology capable of providing accurate information about the overall effectiveness of an I/M program. The goal of this action is to allow states additional flexibility to use not only IM240 but other approved alternative methodologies for their program evaluation. Today's action also clarifies that such program evaluation testing shall begin no later than November 30, 1998, and is not required to be coincident with program start up (though the first report is still due two years after program start up). This action also clarifies that ``initial test'' simply means that the test is conducted before repairs for each test cycle, and does not therefore preclude states from using alternative sampling methodologies such as roadside pullover to sample the fleet.
