The powers conferred by this Act shall be liberally construed in order to accomplish their purposes and shall be in addition and supplemental to the powers conferred by any other law. If any other law or rule is inconsistent with this Act, this Act is controlling as to any public-private agreement entered into under this Act. To implement the powers conferred by this Act, the responsible public entity may establish rules and procedures for the procurement of a public-private agreement under this Act. Nothing contained in this Act is intended to supersede applicable federal law or to foreclose the use or potential use of federal funds. In the event any provision of this Act is inconsistent with applicable federal law or would have the effect of foreclosing the use or potential use of federal funds, the applicable federal law or funding condition shall prevail, but only to the extent of such inconsistency.
