Since the Program EIR and the Final EIR were finalized, there have bee n no substantial project changes and no substantial changes in project circumstances that would require major revisions to the F inal EIR due to the involvement of new significant environmental effects or an increase in the severity of previously identified significant impacts, and there is no new information of substantial importance that would change the conclusions set forth in the Final EIR.
