(a) Between July 1, 2002 and August 1, 2002, the Department shall publish a list of the municipalities with a population of less than 500,000 that have, at any time before the effective date of this Act, enacted ordinances imposing any taxes or fees authorized by subparagraph 1 of § 8-11-2 of the Illinois Municipal Code, § 8-11-17 of the Illinois Municipal Code, or Section 20 of the Telecommunications Infrastructure Maintenance Fee Act. Such list shall include the name of each such municipality, the rates at which such taxes or fees are imposed as of the effective date of this Act, and the rate of the new Simplified Municipal Telecommunications Tax, as calculated pursuant to Section 5-30 of this Act.
     (b) In compiling the list described in this Section, the Department shall collect information from retailers, municipalities, the Illinois Commerce Commission, and other sources deemed by the Department to be reliable.
     (c) Any municipality appearing on the list published pursuant to this Section shall not be required to adopt and file an ordinance implementing the tax authorized by this Act. The list shall be conclusive evidence of the imposition of the tax authorized by this Act at the rate appearing on such list. Any tax imposed in such manner shall take effect with respect to gross charges billed by telecommunications retailers on or after January 1, 2003. A municipality may alter such tax only by filing an ordinance with the Department pursuant to Section 5-20 of this Act.
