The affairs of a solid waste disposal district shall be managed by a board which shall consist of 5 trustees. If the boundaries of the district are coextensive with the boundaries of one county, the trustees shall be residents of that county. If the district embraces 2 counties, 3 trustees shall be residents of the county with the larger population and 2 trustees shall be residents of the other county. If the district embraces 3 counties, one trustee shall be a resident of the county with the smallest population and each of the other counties shall have 2 resident trustees. If the district embraces 4 counties, 2 trustees shall be residents of the county with the largest population and each of the other counties shall have one resident trustee. If the district embraces 5 counties, each county shall have one resident trustee.
In the case of a district composed of one or more townships organized as a result of a petition under subparagraph (b) of Section 4, the trustees shall be residents of the township or townships in the same numerical proportions based upon township population as provided in this Section for counties.
Trustees shall be qualified voters of such district who do not hold any other public office and are not officers of any political party. Trustees shall be selected on the basis of their demonstrated interest in the purpose of solid waste disposal districts.
In a district organized as a result of a petition under subparagraph (a) of Section 4, the presiding officer of the county board of the county of which the trustee is required to be a resident, with the advice and consent of that county board, shall appoint the first trustees. In a district organized as a result of a petition under subparagraph (b) of Section 4, the township supervisor of the township of which the trustee is required to be a resident, with the advice and consent of that township's board of township trustees, shall appoint the first trustees. The first trustees of any district shall hold office for terms expiring on June 30 after one, 2, 3, 4 and 5 year periods respectively as determined and fixed by lot. Thereafter, successor trustees shall be appointed in the same manner not later than June 1 prior to the commencement of term of the trustee.
Each successor trustee shall serve for a term of 5 years. A vacancy occurring otherwise than by expiration of term shall be filled for the unexpired term by appointment of a trustee by the presiding officer of the county board of the county of which the trustee shall be a resident with the advice and consent of that county board or, in a district organized as a result of a petition under subparagraph (b) of Section 4, by appointment of a trustee by the township supervisor of the township of which the trustee is required to be a resident with the advice and consent of that township's board of township trustees. A trustee who has served a full term of 5 years is ineligible to serve as a trustee for a period of one year following the expiration of his term. When any trustee during his term of office shall cease to be a bona fide resident of the district he is disqualified as a trustee and his office becomes vacant.
Trustees shall serve without compensation, but may be paid their actual and necessary expenses incurred in the performance of their official duties.
A trustee may be removed for cause by the presiding officer of the county board of the county of which the trustee is a resident or by the township supervisor of the township from which the trustee was appointed, as appropriate, but every such removal shall be by a written order, which shall be filed with the county clerk of the county wherein the order was issued.
