5 ILCS 220/3.2a
Whenever this Act, as amended from time to time, grants a municipal joint action agency the power to organize and exercise powers in connection with the efficient and environmentally sound collection, transportation, processing, storage and disposal of municipal waste ("waste disposal"), a municipality in the State of Illinois acting as a lead agency ("municipal lead agency") in cooperation with other units of local government to accomplish waste disposal may, by passage of an ordinance to that effect by the municipal lead agency and by the other cooperating units of local government, cause the municipal lead agency to possess all the powers of a municipal joint action agency as if the municipal lead agency were established as a municipal joint action agency under this Act, and also cause the other cooperating units of local government to possess the same powers to enter into contracts and perform those acts as they would with a municipal joint action agency. The corporate authorities of the municipal lead agency shall exercise the powers as are given the Board of Directors of the municipal joint action agency. Copies of the ordinances of the municipal lead agency and the other cooperating units of local government to operate under this Section shall be filed with the Secretary of State.
