S.D. Codified Laws § 6-8B-23
If any bonds become prepayable under any option or provision therein contained, notice of the call for redemption may be made by publication once a week for two consecutive weeks in a newspaper of general circulation serving the public body and, if directed by the governing body, in any other newspaper or publication. Alternatively, the notice may be given by mailing it to the place where the bonds are payable and to the holder of each bond to be redeemed, if the holder's name and address is known. The notice of redemption shall contain a description of the bonds to be redeemed and the redemption date and shall state that on the redemption date, not less than thirty days after the date of the first publication or the mailing of the notice, all interest on the bonds shall cease.
