What you may be alluding to is a notice that says something like "Transactions may be approved that will overdraw your account and result in overdraft fees." That is a notice suggested by the 2005 interagency guidance on overdraft protection programs as a "second best" if an institution is unable to provide a "best practice" of notifying a consumer when completing a withdrawal at the ATM may trigger overdraft fees.
That best practice has not be superseded by any intervening guidance or rule, to the best of my knowledge.
