PRELIMINARY STATEMENT RELATED

TO FERC GAS TARIFF FIRST REVISED VOLUME NO. 1-A

CONTAINING TRANSPORTATION RATE SCHEDULES

This FERC Gas Tariff, First Revised Volume No. 1-A of Northwest

Pipeline Corporation ("Northwest" or "Transporter") contains general

transportation rate schedules available for Shippers with whom Northwest

contracts through executed Transportation Agreements for transportation of

natural gas.

Transportation arrangements commenced by Northwest prior to the

effectiveness of this FERC Gas Tariff, First Revised Volume No. 1-A were

generally undertaken pursuant to special individual contracts. Such

individual contracts are either generally filed as part of Northwest's FERC

Gas Tariff, Original Volume No. 2, or are self-implementing agreements under

Part 284 or Section 157.209 of the Federal Energy Regulatory Commission's

Regulations. In addition, the following special transportation rate

schedules are included in Northwest's FERC Gas Tariff, Second Revised Volume

No. 1:

Rate Schedule T-1: Special Transportation Service from

Stanfield to Ignacio.

In those instances where, in Northwest's determination, the desired

transportation service involves special operating conditions or

circumstances not within the purview of the general rate schedules contained

in this FERC Gas Tariff, First Revised Volume No. 1-A, Northwest may enter

into special transportation agreements for such transportations that may be

included in Northwest's FERC Gas Tariff, Original Volume No. 2.

The Rate Schedules contained in this FERC Gas Tariff, First Revised

Volume No. 1-A are for mainline transportation. For the purposes of this

Volume No. 1-A Tariff, Northwest's mainline transportation system shall be

deemed to include Northwest's mainline(s) extending generally from the

U.S./Canadian border near Sumas, Washington to a point near Ignacio,

Colorado, all sales laterals, including but not limited to the Eugene,

Spokane, Wenatchee, Kellogg, Reno, Red Wash, Piceance Creek and Nucla

Laterals and any other pipelines or laterals owned in whole or in part by

Northwest which are utilized to provide jurisdictional transportation of

natural gas where the service does not qualify for the gathering exemption

of Section 1(b) of the Natural Gas Act.
