The Comptroller may serve a notice of suspension or order of removal or prohibition pursuant to 12 U.S.C. 1818(g) on an institution-affiliated party. A copy of such notice or order will be served on any depository institution that the subject of the notice or order is affiliated with at the time the notice or order is issued, whereupon the institution-affiliated party involved must immediately cease service to, or participation in the affairs of, that depository institution and, if so determined by the OCC, any other depository institution. The notice or order will indicate the basis for suspension, removal or prohibition and will inform the institution-affiliated party of the right to request in writing, to be received by the OCC within 30 days from the date that the institution-affiliated party was served with such notice or order, an opportunity to show at an informal hearing that continued service to or participation in the conduct of the affairs of any depository institution has not posed, does not pose, or is not likely to pose a threat to the interests of the depositors of, or has not threatened, does not threaten, or is not likely to threaten to impair public confidence in, any relevant depository institution. The written request must be sent by certified mail to, or served personally with a signed receipt on, the District Deputy Comptroller in the OCC district in which the bank in question is located; if the bank is supervised by Large Bank Supervision, to the Senior Deputy Comptroller for Large Bank Supervision for the Office of the Comptroller of the Currency; if the bank is supervised by Mid-Size/Community Bank Supervision, to the Senior Deputy Comptroller for Mid-Size/Community Bank Supervision for the Office of the Comptroller of the Currency; or if the institution-affiliated party is no longer affiliated with a particular national bank, to the Deputy Comptroller for Special Supervision, Washington, DC 20219. The request must state specifically the relief desired and the grounds on which that relief is based. For purposes of this section, the term depository institution means any depository institution of which the petitioner is or was an institution-affiliated party at the time at which the notice or order was issued by the Comptroller.
