A hearing on an experimental service change as described by Section 452.116 to remain in effect for more than 180 days may be held before or during the experimental service change period and satisfies the requirement for a public hearing if the hearing notice required by Section 452.118 states that the experiment may become permanent at the end of the period. If a hearing is not held before or during the experimental service change period, the service that existed before the change must be reinstituted at the end of 180 days and a public hearing held in accordance with Section 452.118 before the experimental service may be continued.
