The EPA approves submitted changes to Ohio's enhanced vehicle inspection and maintenance program (known as E-Check) as a revision to the State Implementation Plan (SIP) for ozone in all areas where the State's inspection and maintenance (I/M) program is operated. The EPA's action is based upon a request for a revision which was received by EPA from Ohio on August 29, 1996. The revision includes a vehicle repair spending cap and a temporary hardship extension of time for automobile owners with failed vehicles to perform necessary repairs on vehicles which fail the E-Check test. The repair spending cap does not affect vehicles which require repairs and are under manufacturer warranty; it also does not apply to owners whose vehicles have been mal-maintained or whose emission control devices have been tampered with. The extension of time applies to the automobile owner to which the immediate repair of the failed vehicle would present a hardship. The changes to the E-Check program are the result of concerns expressed by citizens affected by the program in the areas where E- Check has been implemented, and by Ohio legislators representing them. The rule changes do not affect the emission reduction potential of the measure, and, therefore, do not affect the expected emission reductions in the maintenance plan for Cleveland and Dayton or in the 15 percent reasonable further progress plan for Cincinnati. Therefore, the EPA is approving the changes to the rule.
