(b) There shall be within the general fund a separate account which shall be designated and known as the state purposes account and shall reflect all expenditures made for state purposes. 3. Notwithstanding any inconsistent provision of subdivision five of section four of this chapter, any moneys in the general fund not required for cash disbursements pursuant to general fund appropriations may, in amounts determined and certified by the director of the budget, be transferred to the capital projects fund or any debt service fund for the purpose of making payments from such fund pursuant to appropriations by law, provided that, any balance of moneys so transferred, remaining in such fund at the close of each month shall be returned to the general fund. No such transfer shall be made until a certificate of approval of availability for so much as shall be necessary to make disbursements pursuant to appropriations by law from such capital projects or debt service fund for the balance of the month shall have been issued by the budget director and a copy of such certificate of approval filed with the state comptroller, the chairman of the senate finance committee and the chairman of the assembly ways and means committee. 4. (a) Any balance of moneys in any debt service fund in excess of both the debt principal and interest payments required to be made from such fund during the current fiscal year, or during future fiscal years, and any reserve requirement established by statute or by a relevant bond covenant, shall be transferred to the general fund. * (b) On or before the beginning of each quarter, the director of the budget may certify to the state comptroller the estimated amount of monies that shall be reserved in the general debt service fund for the payment of debt service and related expenses payable by such fund during each month of the state fiscal year, excluding payments due from the revenue bond tax fund. Such certificate may be periodically updated, as necessary. Notwithstanding any provision of law to the contrary, the state comptroller shall reserve in the general debt service fund the amount of monies identified on such certificate as necessary for the payment of debt service and related expenses during the current or next succeeding quarter of the state fiscal year. Such monies reserved shall not be available for any other purpose. Such certificate shall be reported to the chairpersons of the Senate Finance Committee and the Assembly Ways and Means Committee. The provisions of this paragraph shall expire June thirtieth, two thousand twenty. * NB Expires June 30, 2020
