1. If it is found that a dam or reservoir presents a threat to public safety, life or property, or that the safety of the dam or reservoir is threatened, the permit for the dam or reservoir shall be suspended and shall be reinstated only when the owner at his expense has completed the necessary alteration or has established such operational procedures as the council upon hearing the recommendations of the chief engineer deems necessary for protection of the public safety, life, property, the dam or reservoir. If necessary for such protection, the council may require the owner at his expense to remove the dam or reservoir, or if the owner refuses or neglects to act, the state may alter or remove the dam or reservoir, and the chief engineer may recover the costs of such action as provided in section 236.450.

2. If the owner refuses to alter or remove a dam or reservoir as directed when found to be a threat as set forth in sections 236.400 to 236.500, he shall be in violation of sections 236.400 to 236.500 and the permit requirements hereunder, and such action shall subject the owner to the enforcement provisions contained herein and revocation of the permit.
