If the annexation of territory in a district by an existing municipality or the creation of a new municipality takes in the property on which an existing fire station is located or reduces the size of the district so that the association, after approval of a majority vote of member departments in good standing, determines that the remaining territory is not of sufficient size to continue to support a department, the association shall request the municipality to assume any indebtedness or financial obligations of the department, provided the department transfers ownership of the fire station and department-owned equipment to the municipality.
