The rates, operator service charges, and surcharges assessed by AOS providers to their end-users of AOS service shall be limited to those specified in Commission-approved tariffs. All rates, operator service charges, and surcharges shall be stated in the tariffs. Location-specific surcharges imposed by the aggregator may only be charged once, either on the AOS bill or at the aggregator location, but under no circumstances shall a location-specific surcharge be imposed both on the bill and at the aggregator location.
