They unsuccessfully claimed that “the Transport Rule allowances in the Plan are not ‘better than BART.'” Of note in this opinion is that, reviewing 42 U.S.C. § 7607(b), two of the three judges on the panel concluded that the Eighth Circuit has jurisdiction because the state implementation plans’ (SIP) reliance on the Transport Rule was based on local issues.
