As Harvey's pal, Elwood, said earlier, there simply are no maturity notice requirements for non-renewing time deposits with terms of under one year. The deposits you describe simply become non-interest-bearing demand deposits (by definition in Regulation D -- 12 CFR part 204 -- and by contract).
When Regulation DD was first proposed, I worked with a group at the ABA that drafted a response to the Federal Reserve's proposal. Our recommendation, adopted by the Fed, said that there need not be a maturity notice under the regulation for these short-term accounts, since the depositors should have a memory or record of the impending maturity date.
So, unless state law compels you to send a maturity notice, you don't have to (my more seasoned view now agrees with Elwood's that a maturity notice would nonetheless be a courtesy, and I recommend it). Because there's no renewal anticipated in the deposit contract, it makes no sense to include disclosures that would be required if the account automatically renews. You could include with that optional maturity notice a rate card (compliant with the advertising rules for time deposits and with the Member FDIC statement, of course) for your current CD offerings in case the customer wants to reinvest the funds.
