The board, in the legislation authorizing the issuance of the bonds, shall provide that they shall not constitute general obligations of the county or be secured by the general credit and taxing power of the county, but shall be payable solely, as to principal and interest, from the revenues of the improvement, constructed with the proceeds of the sale of the bonds, as derived from the rates or charges established for such services under section 343.08 of the Revised Code, in which event the board of county commissioners of a county district or the board of directors of a joint district shall covenant to fix rates or charges sufficient to provide adequate funds for that purpose, after payment of the cost of management, maintenance, and operation of the solid waste collection or other solid waste facilities, and the board of directors of a joint district shall covenant to pay over to counties issuing the bonds adequate funds derived from the rates or charges to pay the principal and interest on the bonds.
The surplus net revenues in any year, over and above the amount of principal and interest payable in that year and any additional amount as is provided in the resolution authorizing the bonds to be held as a reserve for debt service, may be used for the enlargement and replacement of the solid waste collection or other solid waste facilities.
