(a) Each participant receiving cost-share assistance is responsible for the required maintenance and proper use of the practice. Some practices have an established life span or minimum period of time during which they are expected to function as a conservation practice with proper maintenance. Cost-share assistance shall not be authorized for normal upkeep or maintenance of any practice.

(b) If a practice is not properly maintained for the established life span, the participant may be required to refund all or part of cost-share assistance received. The Deputy Administrator will determine what constitutes failure to maintain a practice and the amount that must be refunded.
