2 U.S.C. § 661f
This subchapter shall supersede, modify, or repeal any provision of law enacted prior to November 5, 1990, to the extent such provision is inconsistent with this subchapter. Nothing in this subchapter shall be construed to establish a credit limitation on any Federal loan or loan guarantee program.
Collections resulting from direct loans obligated or loan guarantees committed prior to October 1, 1991, shall be credited to the liquidating accounts of Federal agencies. Amounts so credited shall be available, to the same extent that they were available prior to November 5, 1990, to liquidate obligations arising from such direct loans obligated or loan guarantees committed prior to October 1, 1991, including repayment of any obligations held by the Secretary of the Treasury or the Federal Financing Bank. The unobligated balances of such accounts that are in excess of current needs shall be transferred to the general fund of the Treasury. Such transfers shall be made from time to time but, at least once each year.
