Iowa Code Title XI. Natural Resources [Chs. 455-485] § 455B.139. Emergency orders

If the director has evidence that any person is causing air pollution and that such pollution creates an emergency requiring immediate action to protect the public health and safety, or property, the director may, without notice, issue an emergency order requiring such person to reduce or discontinue immediately the emission of air contaminants. A copy of the emergency order shall be served by personal service. An emergency order issued by the director may be appealed to the commission. After hearing on appeal, the commission may affirm, modify or rescind the order of the director.
