Emergency orders.

Whenever the department finds that an emergency exists which requires immediate action to protect the public health and safety or the environment, the department may, without notice or hearing, issue an order stating the existence of such emergency and requiring that such action be taken as is necessary to meet the emergency. Notwithstanding any provision of this chapter, such order shall be effective immediately. Any person to whom such order is directed shall comply therewith immediately and, on application to the department, shall be afforded a hearing within 10 days. On the basis of such hearing, the emergency order may be continued, modified, or revoked within 30 days after such hearing, as the department deems appropriate under the evidence.
