S.D. Codified Laws § 11-7-29
A commission shall have further power to include in any contract for financial assistance with the federal government any conditions which the federal government may attach to its financial aid of a project, not inconsistent with the purposes of this chapter; and in any contract with the federal government for annual contributions to a commission, the commission may obligate itself (which obligation shall be specifically enforceable and shall not constitute a mortgage, notwithstanding any other laws) to convey to the federal government possession of or title to the project to which such contract relates, upon the occurrence of a substantial default (as defined in such contract) with respect to the covenants or conditions to which the commission is subject; such contract may further provide that in case of such conveyance, the federal government may complete, operate, manage, lease, convey, or otherwise deal with the project in accordance with the terms of such contract; provided, that the contract requires that, as soon as practicable after the federal government is satisfied that all defaults with respect to the project have been cured and that the project will thereafter be operated in accordance with the terms of the contract, the federal government shall reconvey to the commission the project as then constituted.
