Take notice that on January 30, 2004, Northern Natural Gas Company (Northern) tendered for filing as part of its FERC Gas Tariff, Fifth Revised Volume No. 1, the revised tariff sheets set forth in Appendix A to the filing.

Northern states that the tariff sheets are being filed to effectuate changes in the rates and terms applicable to Northern's jurisdictional services. The effect of the rate case is an overall increase in revenues of approximately $29.6 million above the annual revenue requirement established in Northern's 2003 rate case.

The changes reflected in the Revised Tariff Sheets to be effective March 1, 2004, are required to effectuate the rate increase and to make certain changes to Northern's tariff. In addition, Northern proposes Pro Forma Tariff Sheets which reflect further changes to become effective on a prospective basis following a Commission order on the merits or a settlement of this proceeding.
