(3) The Department has made reasonable efforts to obtain payment of the debt, and has:

For purposes of this regulation, the Department has made a reasonable attempt to notify the debtor if the agency uses the current address information contained in the Department's records related to the debt. If address validation is desired or necessary, the Department may obtain information from the IRS pursuant to 26 U.S.C. 6103(m)(2)(4) or (5).

(iv) Provided the debtor with an opportunity to make a written agreement to repay the debt; and
(4) The debt is at least $25.

(ii) The amount of such past-due and legally enforceable debt;
(iii) The date on which the debt became past-due; and
(iv) The designation of the Department referring the debt.
(c) Correcting and updating referral.
(1) After referring a debt under this part, the Secretary shall promptly notify the Department of the Treasury if:
(i) An error was made with respect to information transmitted to the Department of the Treasury;
(iii) The debt amount is otherwise incorrect.
(d) Rejection of certification. If the Department of Treasury rejects a certification because it does not comply with the requirements of paragraph (a) of this section, upon notification of the rejection and the reason(s) for rejection, the Secretary will resubmit the debt with a corrected certification.
