12 U.S. Code § 4003 - Safeguard exceptions
In the case of any funds deposited in such account by a check (other than a check described in subparagraph (C) or (D) of paragraph (1)), the availability for withdrawal of such funds shall not be subject to the provisions of section 4002(b), 4002(c), or paragraphs  (1) of section 4002(e) of this title.
In accordance with regulations which the Board, jointly with the Director of the Bureau of Consumer Financial Protection, shall prescribe, subsections (a)(2), (b), (c), and (e) of section 4002 of this title shall not apply with respect to any check deposited in an account at a depository institution if the receiving depository institution has reasonable cause to believe that the check is uncollectible from the originating depository institution. For purposes of the preceding sentence, reasonable cause to believe requires the existence of facts which would cause a well-grounded belief in the mind of a reasonable person. Such reasons shall be included in the notice required under subsection (f).
No determination under this subsection may be based on any class of checks or persons.
Each agency referred to in section 4009(a) of this title shall monitor compliance with the requirements of this subsection in each regular examination of a depository institution and shall describe in each report to the Congress the extent to which this subsection is being complied with. For the purpose of this paragraph, each depository institution shall retain a record of each notice provided under subsection (f) as a result of the application of this subsection.
No regulation prescribed or order issued under paragraph (1) shall remain in effect for more than 45 days (excluding Saturdays, Sundays, legal holidays, or any day either House of Congress is not in session).
Within 10 days of prescribing any regulation or issuing any order under paragraph (1), the Board, jointly with the Director of the Bureau of Consumer Financial Protection, shall transmit a report of such action to the Committee on Banking, Finance and Urban Affairs of the House of Representatives and the Committee on Banking, Housing, and Urban Affairs of the Senate.
If the facts upon which the determination of the applicability of an exception contained in subsection (b) or (c) to any deposit only become known to the receiving depository institution after the time notice is required under paragraph (2) with respect to such deposit, the depository institution shall mail such notice to the depositor as soon as practicable, but not later than the first business day following the day such facts become known to the depository institution.
