The health professions education fund
created within the Treasury by section 744(d)(1) of the Public Health Service
Act (as in effect before the date of enactment of this Act) [former 42 U.S.C. 294d(d)(1)
] shall remain available to the Secretary of Health, Education, and Welfare [now Health and Human Services] for the purpose of meeting his responsibilities respecting participations in obligations acquired under such section. The Secretary shall continue to deposit in such fund all amounts received by him as interest payments or repayments of principal on loans under such section 744 [former 42 U.S.C. 294d
]. If at any time the Secretary determines the moneys in the fund exceed the present and any reasonable prospective future requirements of such fund, such excess may be transferred to the general fund of the Treasury.
