Abstract
This final rule amends regulations governing EPA's Urban Bus Retrofit/Rebuild Program to provide for the revision of post-rebuild particulate levels based on equipment certified by July 1, 1998. This amendment allows equipment manufacturers additional time to certify equipment capable of influencing compliance under Option 2 (the fleet averaging option) of the program. This amendment provides assurance that the two compliance options of the program remain equivalent, and that urban buses utilize the best retrofit technology reasonably achievable as Congress required. In addition, the amendment provides assurance that urban areas realize the full PM benefits of this program.
