The commission may approve an appropriate and reasonable cost recovery mechanism to allow the capable proximate utility to recover its acquisition costs and projected cost of service of operating, maintaining and improving the facilities of the failing water or wastewater utility or its net costs incurred for operating, maintaining and improving the distressed utility under an operating agreement. The cost recovery mechanism may include a surcharge or surcharges on both acquired and existing customers if approved by the commission in a separate rate or tariff proceeding which shall be considered by the commission on an expedited basis without the need for a full base rate proceeding. Rate increments and surcharges established pursuant to this section shall be subject to adjustment on an annual basis to reflect changes in costs, additional projected capital and operating costs and true-up of any over or under recoveries of costs. Cost recovery mechanisms may also include:
