(1) Each county and municipality shall make a good faith effort to estimate the cost of garbage and rubbish collection and disposal services. These costs may be met, in amounts necessary to defray the cost of the system, by any combination of generator fees, ad valorem tax revenues as authorized under Section 19-5-21 or Section 21-19-2, or county or municipal special funds as authorized under Section 19-5-21 or 21-19-2.
(2) Nothing in Chapter 624, Laws of 1994, shall be construed to abrogate or cancel any contract that a county or a municipality has entered into for garbage or rubbish collection or disposal. If a county or municipality entered into a contract before April 1, 1994, and the term or period of performance of that contract does not exceed five (5) years, the county or municipality may continue to levy the ad valorem tax assessment in effect before April 1, 1994, to honor the contract for the term of that contract.
