The report discusses the test procedures recommended for current technology vehicles. The test procedures presented in this report represent the best technical information the Environmental Protection Agency Motor Vehicle Emission Laboratory has on how to test current motor vehicles and do not represent a new requirement at this time. EPA recognizes that for Inspection and Maintenance (I/M) programs to adopt these new procedures, changes in regulations, rewriting test protocols, software and, in some cases, hardware upgrades, and other changes would be needed and would require time to implement. This report is being released at this time so that programs may take advantage of any opportunities that arise to update the test procedures as they make other program changes, including changes necessary to comply with requirements of the 1990 amendments to the Clean Air Act. EPA has not yet considered whether states and localities should be required to eventually adopt and implement a test from among those described here.
