Sec. 8.02. ELECTION TO PARTICIPATE IN DROP. The election to participate in the DROP shall be made in accordance with procedures adopted by the board of trustees. The election may be made at any time on or after the date the member becomes eligible for normal service retirement under Section 5.01 of this Act or early retirement under Section 5.05 of this Act and becomes effective on the first day of the first month after the date of the election. At the same time that a member makes an election to participate in the DROP, the member must agree in writing to terminate service with the fire department on a date not later than the seventh anniversary of the effective date of the election under this section. An agreement to terminate service is binding on the member and the fire department, except that the member may terminate active service at any time before the date selected. An election to participate in the DROP has no effect on either the municipality's or the member's contributions under Section 10.01 of this Act.
