When any Indian owner of land not under lease to a non-Indian is filnancially unable to pay the operation and maintenance charges on the due date, the Superintendent may make the necessary arrangements with such Indian owner as will permit him to perform labor on the irrigation project works, the proceeds derived therefrom to be applied in partial payment of such charges. The Superintendent may also make necessary arrangements for such Indian owner to pay the operation and maintenance charges from the proceeds of the crops grown on the land when harvested and marketed within that calendar year, provided written arrangements to that effect are made with the Superintendent by the Indian owner prior to the delivery of water.

(b) In any instance where the Superintendent is convinced that an Indian landowner, whose land is not under lease to a non-Indian, is financially unable to pay his operation and maintenance charges from proceeds of labor performed on the project works, or from the proceeds of the crops being grown on the land, or from any other source, the delivery of water may be made to the land

if a written certificate is issued by the Superintendent stating that such Indian landowner is not financially able to pay such charges. In such cases the unpaid charges shall be entered on the accounts and will stand as a first lien against the land until paid but without penalty for delinquency.

§ 221.193 Water users' responsibility for water after delivery.
