If any municipal corporation establishes a department to exercise any of the powers conferred by sections 745.01 to 745.14, inclusive, of the Revised Code, such department is hereby granted such powers of supervision and regulation of any public utility operating under an indeterminate grant as are provided by such sections and the ordinance granting the permit, and as are prescribed by any ordinance not inconsistent with the ordinance granting the permit. Each such public utility shall comply with all orders and regulations of such department issued by virtue of the powers granted by this section. The procedure of, by, and before such department shall be as ordained by the legislative authority of the municipal corporation in the permit and other ordinances. The legislative authority may prescribe the penalties for noncompliance with and the methods of enforcement of the orders and regulations of such department, not inconsistent with the ordinance granting the permit. The permit or any ordinance or order of the municipal corporation passed or issued under sections 745.01 to 745.14, inclusive, of the Revised Code, shall be binding upon all public officers and commissions.
