SDCL § 45-6C-28: Capping, sealing, and plugging of test holes--Temporary delay.

The operator shall cap, seal, and plug each test hole sunk for exploratory purposes on all public and private lands within the state immediately following the drilling and probing. An operator may apply, in writing, to the Board of Minerals and Environment for permission to temporarily keep the test hole open. The board may, in its discretion, allow the operator a temporary delay, if the test hole is securely covered in a manner which will prevent injury to persons or animals and marked in a manner approved by the board.
