Northern is submitting the attached tariff sheets to implement an optional volumetric firm throughput service under new Rate Schedule VFT. This service will be available to new customers and as a conversion option for Northern's current firm customers under Rate Schedules TF and TFX. The rate for VFT service will be a one-part volumetric rate derived from Northern's current firm rates. For current Northern firm customers, VFT service permits a customer to convert all of its long-term (i.e., one year or more) firm transportation entitlement to a one-part, volumetric rate based on the customer's historical load factor. VFT service is also available to new customers desiring long-term capacity on Northern's system and would be based on the customer's projected load factor.

Northern states that copies of the filing were served upon Northern's customers and interested State Commissions.

Any person desiring to be heard or to protest said filing should a motion to intervene or a protest with the Federal Energy Regulatory Commission, 888 First Street, N.E., Washington, D.C. 20426, in accordance with Sections 385.214 or 385.211 of the Commission's Rules and Regulations. All such motions or protests must be filed in accordance with Section 154.210 of the Commission's Regulations.
