31 CFR 501.709 - Penalty notice.
(a) If, after considering any written response to the Prepenalty Notice, and any other relevant facts, the Director determines that there was a violation by the respondent and that a monetary penalty is warranted, the Director promptly shall issue a Penalty Notice informing the respondent that, absent a timely request for an administrative hearing, the Director will impose the civil monetary penalty described in the Penalty Notice. The Penalty Notice shall inform the respondent:
(2) That in the absence of a timely request for a hearing, the issuance of the Penalty Notice constitutes final agency action;
(3) That, absent a timely request for a hearing, payment (or arrangement with the Financial Management Service of the Department for installment payment) of the assessed penalty must be made not later than 30 days after the date of service of the Penalty Notice; and
(4) That absent a timely request for a hearing, the respondent must furnish respondent's taxpayer identification number pursuant to 31 U.S.C. 7701 and that the Director intends to use such information for the purposes of collecting and reporting on any delinquent penalty amount in the event of a failure to pay the penalty imposed.
