All federal funds received must be deposited in the State Treasury, if not in conflict with federal regulations, and withdrawn from the State Treasury as needed, in the same manner as that provided for the disbursement of state funds. If it is determined that federal funds are not available for, or cannot be appropriately used in connection with, all or any part of any activity or program for which state funds are specifically appropriated for the fiscal year to match federal funds, the appropriated funds may not be expended and must be returned to the general fund, except upon specific written approval of the State Fiscal Accountability Authority. Donations or contributions from sources other than the federal government, for use by any state agency, must be deposited in the State Treasury, but in special accounts, and may be withdrawn from the treasury as needed to fulfill the purposes and conditions of the donations or contributions, if specified, and if not specified, as directed by the proper authorities of the department. The expenditure of funds by state agencies from sources other than general fund appropriations are subject to the same limitations and provisions of law applicable to the expenditure of appropriated funds with respect to salaries, wages or other compensation, travel expense, and other allowance or benefits for employees.
