California Code, Public Utilities Code - PUC § 29220

When sufficient money is in the Funding Fund to redeem one or more outstanding past due bonds, notes or other evidences of indebtedness, or to redeem one or more of the outstanding bonds, notes or other evidences of indebtedness, which are subject to call or payment before maturity, and which are proposed to be funded or refunded, the treasurer shall publish a notice that he is prepared to pay the bond, note or other evidence of indebtedness (giving its number, if any). The notice shall be published once a week for two weeks in a newspaper of general circulation in the district, if there is one. Copies of such advertisement may be published in any newspaper or financial publication in the United States. If the bond, note or other evidence of indebtedness to be called for redemption or refunded is not presented for redemption on or before the date specified for redemption, as set forth on the face of such outstanding bond, note or other evidence of indebtedness, interest thereon shall cease.
