Violation of any of the requirements or restrictions of this chapter or of any of the rules adopted pursuant to this chapter is cause for suspension, revocation, or refusal to renew a license. The director shall at the earliest time feasible notify a licensee whose license the board is considering suspending or revoking and shall inform the licensee what changes must be made in the licensee’s operation to avoid such action. The licensee shall be given a reasonable time for compliance, as determined by the director, after receiving such notice or a notice that the board does not intend to renew the license. When the licensee believes compliance has been achieved, or if the licensee considers the proposed suspension, revocation, or refusal to renew unjustified, the licensee may submit pertinent information to the board and the board shall expeditiously make a decision in the matter and notify the licensee of the decision.
