S.D. Codified Laws § 1-54-20

The submission of false or misleading statements or information as part of a grant application or the failure to comply with any requirement shall be considered a default upon the terms of a grant. In the event of a default, the department may require the grant recipient to repay any funds dispersed under the grant to the department within thirty days of a written demand from the department. The department may begin a civil action to recover any grant funds that a grant recipient is required to repay under this section.
