1. The department shall propose a plan to divide the state into proposed solid waste management regions in consultation with the governing bodies of the counties of the state. The department shall propose the boundaries of solid waste management regions by March 1, 1991.

2. The department shall hold public meetings in each of the regions proposed pursuant to subsection 1 of this section within three months of its division of the state into proposed regions. Any county may request that it be placed with another regional grouping, and the department shall authorize any such change if the county clearly and convincingly demonstrates that the change is necessary for effective solid waste management within the county and will not negatively affect the solid waste management system of either region. The department shall adopt final boundaries for the regions by June 30, 1991.

3. Counties may, for the purpose of managing districts, cooperate as provided in sections 260.300 to 260.345 or formulate an alternative management structure agreed to by each county in the district. A solid waste management district, regardless of how formed, shall be governed by an executive board and comply with the provisions of sections 260.200 to 260.345.
