(1) After December 31, 2025, the department of treasury shall notify the commission on a quarterly basis of the balance available for distribution under section 408(4)(b). If the balance available for distribution under section 408(4)(b) exceeds $12,000,000.00 for 3 consecutive quarters, the commission may initiate a proceeding to reduce the state 9-1-1 charge in section 401a and the prepaid wireless 9-1-1 surcharge under section 401c proportionately to ensure that the average quarterly balance to be distributed under section 408(4)(b) is sufficient to reimburse at least 6 months of ongoing approved costs related to transport, routing, or delivery to PSAPs of IP-based 9-1-1 emergency service.

  (2) If all emergency 9-1-1 districts in this state have not been fully converted to or contracted with an IP-based 9-1-1 service provider at the time of the proceeding under subsection (1), the commission shall take that into consideration along with any incurred cost that has not been reimbursed to the IP-based 9-1-1 service provider when determining the reduction described in subsection (1).

  (3) The commission may request from the department of treasury any data reasonably necessary to make a determination under subsection (1). The department of treasury shall provide the data requested under this subsection in a timely fashion.

  (4) The commission must allow an interested person to intervene in a proceeding under subsection (1).

  (5) Within 180 days after a proceeding commences under subsection (1), the commission shall issue a final order. The commission shall notify the legislature and IP-based 9-1-1 service providers of a final order within 10 days of issuing the final order.

  (6) Reductions to the state 9-1-1 charge under section 401a and the prepaid wireless 9-1-1 surcharge under section 401c take effect 60 days after the commission issues a final order under subsection (5).
