The Board shall have power to pass all ordinances and make all rules and regulations proper or necessary to carry into effect the powers granted to the Authority, with such fines or penalties as may be deemed proper. No fine or penalty, however, shall exceed $500 and no imprisonment authorized by this Section for failure to pay any fine, penalty or cost shall exceed 6 months for one offense. All fines and penalties shall be imposed by ordinance, which shall be published in a newspaper of general circulation published in the area embraced by the Authority. No such ordinance shall take effect until ten days after its publication.
     The Board is authorized to recover the fines and penalties imposed for violation of its ordinances by suit in the name of the Authority before the circuit court of Winnebago County. The procedure in such suits shall be the same as that provided by law for like suits for the violation of ordinances in cities organized under the Illinois Municipal Code, and offenders may be imprisoned for nonpayment of fines and costs in the same manner as in such cities. All fines when collected shall be paid into the treasury of the Authority.
