(b) As provided for in the Debt Collection Improvement Act of 1996 (31 U.S.C. 3711(g)(1)), payment offices are required to transfer any debt that is delinquent more than 180 days to the Department of Treasury for collection.

(c) The contracting officer shall periodically follow up with the payment office to determine whether the debt has been collected and credited to the correct appropriation(s).
