Notwithstanding any other provision of law, the board of trustees of a fire protection district may, by majority vote of the board of trustees, adopt a resolution to discontinue the district's emergency ambulance service and to discontinue the district's tax upon certification as provided by this Section if a county that is already providing emergency ambulance service through an intergovernmental agreement levies a tax for emergency ambulance service under Section 5-1028 of the Counties Code and the county has, by ordinance, agreed to assume the emergency ambulance service at the expiration of the intergovernmental agreement between the district and county. A resolution adopted under this Section must include an end date of services. Upon certification to the county clerk by both the county and the district that all criteria have been met under this Section and Section 5-1028.2 of the Counties Code, the district may not levy a tax for emergency ambulance service under Section 22 unless the county repeals the ordinance adopted under Section 5-1028.2 and the county's tax adopted under Section 5-1028. If the district elects to no longer provide emergency ambulance service under this Section, the election shall not be construed as affecting the district's authority to levy a tax and provide fire protection service under this Act.
