The Department on behalf of the state shall seek agreement to the provisions of Sections 4 and 5 of this act by the Secretary of Transportation on the basis of their being consistent with federal laws and customary usages and zoning principles and standards which hold and govern in this state. In the event such an agreement cannot be achieved, this legislation shall be returned to the legislative bodies of the State of Oklahoma for remedial action and resubmission to the Secretary. In the event such a new agreement cannot be achieved, the Department shall promptly institute proceedings of the kind provided for in Title 23 U.S.C.A. 131 (1) in order to obtain a judicial determination as to whether this chapter and the regulations promulgated thereunder provide effective control of outdoor advertising as set forth therein. In such action the Department shall request that the court declared rights, status and other legal relations and declare whether the standards, criteria and definitions contained in the agreement proposed by the Department are consistent with customary use. If such agreement is held by the court in a final judgment to be invalid in whole or in part as inconsistent with customary use or is otherwise in conflict with Title 23 U.S.C.A. 131, the Department shall promptly negotiate with the Secretary of Transportation, or his successor, a new agreement or agreements which shall conform to said statute as interpreted by the court in such action.
