Iowa Admin. Code r. 571-16.30
A dock management area permit may be modified, suspended, or revoked, in whole or in part, by written notice, if the director determines that the dock is not safe, that a violation of any terms or conditions of the permit or these rules has occurred, or that continuation of the permit is not in the public interest. Such modification, suspension, or revocation shall become effective upon a date specified in the notice. The notice shall state the extent of the modification, suspension, or revocation, the reasons for the action, and any corrective or preventative measures to be taken by the permittee to bring the dock, structure, or activity into compliance. Within 30 days following receipt of the notice of a revocation or modification, or during the course of a suspension, the permittee may file a notice of appeal, requesting a contested case pursuant to 571-Chapter 7. The notice of appeal shall specify the basis for requesting that the permit be reinstated.
