S.D. Codified Laws § 49-32-14
If a person desires to carry on a function, activity, work or operation in closer proximity to a high voltage line or conductor than is permitted by §§ 49-32-11 and 49-32-12, or in such proximity that a function could reasonably be expected to come within closer proximity than permitted by said sections, the person responsible for the work to be done shall promptly notify the operator of the high voltage conductors of the work to be performed and make appropriate arrangements with the operator of the high voltage conductors for temporary mechanical barriers, temporary de-energization and grounding of the conductors, or temporary raising of the conductors before proceeding with any work which would impair the clearances required by §§ 49-32-11 and 49-32-12. The operator shall provide the necessary clearance within a reasonable time after notification.
A violation of this section by the person responsible for the work or by the operator of the high voltage lines is a Class 2 misdemeanor.
