(1) At the conclusion of each fiscal year, beginning with Fiscal Year 1992, each unit of local government shall determine during its regular audit the full and complete cost for solid waste management within the service area of the unit of local government for the previous fiscal year, and shall update the full and complete cost every year thereafter. The Department of Audit shall establish the method for units of local government to use in calculating full and complete cost for the preceding fiscal year to be included as a part of the regular audit of the operations of the unit of local government.

(2)

(a) Each unit of local government shall establish a system to inform, no less than once a year, residential and nonresidential users of municipal solid waste management services within its service area of the user’s share, on an average or individual basis, of the full cost for municipal solid waste management as determined pursuant to subsection (1) of this section.

(b) Counties and municipalities are encouraged to operate their municipal solid waste management systems through use of an enterprise fund.

(3) For purposes of this section, “service area” means the area in which the unit of local government provides, directly or by contract, municipal solid waste management services. This section shall not be construed to require a person operating under a franchise agreement to manage municipal solid waste within the service area of a unit of local government to make the calculations or to establish a system to provide information required under this section, unless such person agrees to do so as part of such franchise agreement.
