S.D. Codified Laws § 34A-6-1.26
The secretary may issue an emergency order compelling any person who is committing an act or failing to take action, or threatening either, which violates §§ 34A-6-1.1 to 34A-6-1.38, inclusive, and which will cause substantial pollution, the harmful effects of which cannot be remedied immediately after the commission or cessation of the act to stop, avoid, moderate, or perform the act so that it is in compliance with §§ 34A-6-1.1 to 34A-6-1.38, inclusive, or so that the substantial injury will not occur. The order is effective immediately upon receipt by the person to whom it is directed, unless the secretary provides otherwise. If the order is not complied with in a timely manner, the secretary may take such action as is necessary to contain and recover pollutants to limit or prevent pollution or injury to public health or welfare.
