(A)   SUPPLEMENTAL APPROPRIATIONS: If during the fiscal year the Manager certifies that there are available for appropriation revenues in excess of those previously appropriated, the Council by ordinance may make supplemental appropriations for the year up to the amount of such excess.
   (B)   EMERGENCY APPROPRIATIONS: To meet a public emergency affecting life, health, property, or the public peace or welfare, the Council may make emergency appropriations. Such appropriations may be made by emergency ordinance or resolution in accordance with the provisions of § 4.15. To the extent that there are no available unappropriated revenues to meet such appropriations, the Council may by such emergency ordinance or resolution authorize, as prescribed by law, the issuance of notes, which may be renewed from time to time.
   (C)   REDUCTION OF APPROPRIATIONS: If at any time during the fiscal year it appears probable to the Manager that the revenues available will be insufficient to meet the amount appropriated, the Manager shall report to the Council without delay, indicating the estimated amount of deficit, any remedial action taken by the Manager, and the Manager's recommendations as to any other steps to be taken. The Council shall then take such further action as it deems necessary to prevent or minimize any deficit and, for that purpose, it may by ordinance or resolution reduce one or more appropriations. Council may also initiate this action.
   (D)   TRANSFER OF APPROPRIATIONS: At any time during the fiscal year the Manager may transfer part or all of any unencumbered appropriation balance among programs within a department, office, or agency; and upon written request by the Manager, the Council may by ordinance transfer part or all of any unencumbered appropriation balance from one department, office, or agency to another. Council may also initiate this action. Transfers between different funds shall be made in the manner provided by law.
   (E)   LIMITATIONS - EFFECTIVE DATE: No appropriation for debt service may be reduced or transferred, and no appropriation may be reduced below any amount required by law to be appropriated or by more than the amount of the unencumbered balance thereof. The supplemental and emergency appropriations and reductions or transfer of appropriations authorized by this section may be made effective immediately upon adoption.
