Every RAP project shall be subject to final examination and audit by the state auditor. In the event such an examination reveals an improper certification on the part of a county relative to compliance with provisions of this chapter, the matter shall be placed on the agenda of the next meeting of the county road administration board and may be cause for the board to withdraw or deny the certificate of good practice of that county. The board may also require that all or part of the RATA funds received by the county be returned to the county road administration board.
