If a provider and 1 or more municipalities are unable to agree on arrangements for coordinating and minimizing the disruption of public rights-of-way, ensuring the efficient construction of facilities, restoring the public rights-of-way after construction or other activities by a provider, protecting the public health, safety, and welfare, and resolving disputes arising under this act, the commission shall appoint a mediator within 7 days from the date of the notice to make recommendations within 30 days from the date of the appointment for a resolution of the dispute. If any of the parties are unwilling to comply with the mediator’s recommendations, any party to the dispute may within 30 days of receipt of the recommendation request the commission for a review and determination of a resolution of the dispute. The determination by the commission under this section shall be issued within 60 days from the date of the request to the commission. The commission shall issue its determination within 15 days from the date of the request if a municipality demonstrates that the public health, safety, and welfare require a determination before the expiration of the 60 days. The interested parties to the dispute may agree to an extension for up to 30 days of the 60-day requirement under this section.
