25 CFR § 513.4 - What notice will the Commission give to a debtor of the Commission's intent to collect debts?
(a) When the Chairman determines that a debt is owed to the Commission, the Chairman will send a written notice (Notice), also known as a demand letter. The Notice will be sent by facsimile or mail to the most current address known to the Commission. The Notice will inform the debtor of the following:
(1) The amount, nature, and basis of the debt;
(2) The methods of offset that may be employed;
(5) The Commission's policy concerning interest, penalty charges, and administrative costs, as set out in § 513.5, including a statement that such assessments must be made against the debtor unless excused in accordance with the FCCS and this part;
(6) The date by which payment should be made to avoid late charges and enforced collection;
(8) The debtor's opportunity for review.
(b) A debtor whose debt arises from a notice of violation and/or civil fine assessment that has become a final order and that was subject to the Commission's appeal procedures at 25 CFR parts 580 through 585 may not re-litigate matters that were the subject of the final order.
