Iowa Admin. Code r. 27-10.32
10.32(4) Noncompliance with maintenance/performance agreements. Upon determination by the district and the division that a landowner is not in compliance with a maintenance/performance agreement, the division shall assist the district in the issuance of an administrative order to the landowner requiring appropriate maintenance, repair or reconstruction of the practice, provided voluntary means have been exhausted. The district, in its sole discretion, may allow the landowner or the landowner’s successors to refund to the division the entire amount of the financial incentive payment received by the landowner in lieu of maintaining, repairing or reconstructing a practice.
10.32(5) Agricultural land converted to nonagricultural land. If land subject to a maintenance/performance agreement is converted to a nonagricultural use that does not require a permanent soil and water conservation practice which has been established with financial incentives, the practice shall not be removed until the owner refunds the appropriate amount of the payment received.
