36 C.F.R. § 1201.40 Which debts can NARA refer to the Treasury for collection by offsetting tax refunds?

(1) Is at least $25.00;
(2) Except in the case of a judgment debt, has been delinquent for at least three months and will not have been delinquent more than 10 years at the time the offset is made;
(3) With respect to which NARA has:
(i) Given the debtor at least 60 days to present evidence that all or part of the debt is not past due or legally enforceable;
(ii) Considered evidence presented by the debtor; and
(iii) Determined that an amount of the debt is past due and legally enforceable;
(4) With respect to which NARA has notified or has made a reasonable attempt to notify the debtor that:
