Pursuant to the Federal Clean Air Act (CAA or Act), the Environmental Protection Agency (EPA) is taking direct final action to correct a previously approved diesel inspection and maintenance (I/M) program provision in Albuquerque/Bernalillo County's State Implementation Plan (SIP). This action is based on our determination that at the time EPA approved the diesel I/M Program the State did not have the legal authority to expand its program to require the testing of 1998 and newer diesel motor vehicles greater than 1,000 and less than 10,001 pounds.
