2. The state may proceed against a person who violates a provision of section 461A.4 or refuses to comply with an order issued by the commission pursuant to section 461A.4 by initiating an alternative civil enforcement action in lieu of a criminal prosecution. The amount of the civil penalty shall not exceed five thousand dollars. Each day of a violation shall be considered a separate offense.
