The Township Administrator shall control the expenditure programs of each department through provision of work programs and periodic allotments of budgeted appropriations. No department shall incur any expenditure in excess of the amount so allotted, and no bill, claim or voucher shall be paid for an expenditure made in violation of this section, except upon specific approval of the Council. Whenever it shall appear to the Township Administrator that the amount appropriated for any department or for any purpose within a department is in excess of the amount required to be expended to provide the quantity and quality of services authorized by the budget, the Township Administrator may, by administrative order with the approval of the Council, reduce the amount available for expenditure by any department during the remainder of any year. No expenditure shall be made or incurred, nor shall any bill, claim or voucher be paid, which, together with all prior expenditures, exceeds the amount of the appropriation to any department as so reduced.
