03-13299. Northern Natural Gas Company; Notice of Compliance Filing

May 21, 2003.

Take notice that on May 16, 2003, Northern Natural Gas Company (Northern) tendered for filing to become part of Northern's FERC Gas Tariff, Fifth Revised Volume No. 1 the following tariff sheets to be effective June 1, 2003:

Substitute Fifteenth Revised Sheet No. 61.

Substitute Fifteenth Revised Sheet No. 62.

Substitute Fifteenth Revised Sheet No. 63.

Substitute Fifteenth Revised Sheet No. 64.

Northern states that the filing establishes the fuel and unaccounted for percentages to be in effect June 1, 2003, based on actual data for the 12 month period ended March 31, 2003. The revised tariff sheets are being filed to correct an inadvertent error in the calculation of the MidContinent Mainline fuel percentage. The filing results in a reduction to the previously filed MidContinent Mainline fuel percentage.

Northern further states that copies of the filing have been mailed to each of its customers and interested State Commissions.

Any person desiring to protest said filing should file a protest with the Federal Energy Regulatory Commission, 888 First Street, NE., Washington, DC 20426, in accordance with Section 385.211 of the Commission's Rules and Regulations. All such protests must be filed in accordance with Section 154.210 of the Commission's Regulations.
