  1.  A person violating this chapter or rules adopted by the department under this chapter is guilty of a simple misdemeanor.
  2.  The department shall provide for the prosecution of a violation of this chapter by referring the violation to the county attorney in the county where the violation occurs. The department shall compile evidence of the violation for prosecution. The county attorney shall prosecute any case determined by the county attorney to be meritorious without delay. The department shall not refer a violation to the county attorney until the department provides the person subject to the violation with an opportunity to be heard by the department according to procedures adopted by the department. A right to a hearing is not a contested case proceeding as provided in chapter 17A. The department is not required to refer a minor violation to a county attorney, and may instead issue a warning to the person subject to the minor violation.
