(a) An elected member of a county board is not eligible to participate in the Fund with respect to that position unless the county board has adopted a resolution, after public debate and in a form acceptable to the Fund, certifying that persons in the position of elected member of the county board are expected to work at least 600 hours annually (or 1000 hours annually in a county that has adopted a resolution pursuant to subsection (e) of Section 7-137 of this Code). The resolution must be adopted and filed with the Fund no more than 90 days after each general election in which a member of the county board is elected.
     (b) An elected member of a county board that participates in the Fund with respect to that position shall monthly submit, to the county fiscal officer, time sheets documenting the time spent on official government business as an elected member of the county board. The time sheets shall be (1) submitted on paper or electronically, or both, and (2) maintained by the county board for 5 years. An elected member of a county board who fails to submit time sheets or fails to conduct official government business with respect to that position for either 600 hours or 1000 hours (whichever is applicable) annually shall not be permitted to continue participation in the Fund as an elected member of a county board. The Fund may request that the governing body certify that an elected member of a county board is permitted to continue participation with respect to that position.
