S.D. Codified Laws § 49-41B-39
All right and title in any financial security required by the commission for the decommissioning of wind turbines or solar energy facilities must be controlled by the commission, in accordance with the terms of the financial security agreement or instrument, until the commission by order releases the security. The financial security of the person required to provide it may not be cancelled, assigned, revoked, disbursed, replaced, or allowed to terminate without commission approval.
The commission may require, accept, hold, or enter into any agreement or instrument for the provision of financial security, including any funds reserved or held by any person to satisfy or guarantee the obligation of an owner of wind turbines or solar energy facilities permitted under this chapter, to decommission and remove the wind turbines or solar energy facilities. The form, term, and conditions of the financial security are subject to the approval of the commission. The commission shall determine any claim upon the financial security made by any landowner for decommissioning and removal of turbines or solar energy facilities.
Any financial security provided under this chapter may not be pledged or used as security for any other obligation of the wind turbine or solar energy facilities owner, and is exempt from attachment or mesne process, from levy or sale on execution, and from any other final process issued from any court on behalf of third-party creditors of the owner of the wind turbines or solar energy facilities. Any commission decision based on any claim made by the owner of the wind turbines or solar energy facilities for refund or return of the financial security, or for actual expenses of decommissioning, or any related agreements, may be appealed.
In any case, the commission may appear in court and defend the integrity and viability of the financial security for purposes of decommissioning and removal of wind turbines or solar energy facilities. The commission may not require any financial security from an owner of wind turbines or solar energy facilities who is also a public utility as defined in § 49-34A-1.
