After a hearing on an appealed action, the council shall make specific written findings either denying the appeal or remanding the matter to the state or local public agency for reconsideration of the covered action based on the finding that the certification of consistency is not supported by substantial evidence in the record before the state or local public agency that filed the certification. Upon remand, the state or local agency may determine whether to proceed with the

covered action. If the agency decides to proceed with the action or with the action as modified to respond to the findings of the council, the agency shall, prior to proceeding with the action, file a revised certification of consistency that addresses each of the findings made by the council and file that revised certification with the council.
