Washington Expansion

Washington Expansion Project Overview

Draft EIS issued

On August 5, 2015, the FERC issued a draft environmental impact statement (DEIS) for the Oregon LNG Terminal and Pipeline Project (Oregon LNG) and the Washington Expansion Project. The purpose of the DEIS is to evaluate the potential environmental impacts of constructing and operating the proposed projects according to the requirements of the National Environmental Policy Act.

In the DEIS, FERC staff concluded that any environmental impacts from the project can be reduced by implementing mitigation measures already proposed by both Oregon LNG and Northwest Pipeline. The link to the DEIS is http://elibrary.FERC.gov/idmws/file_list.asp?accession_num=20150805-4003.

Filing of original application

On June 25, 2013, Northwest Pipeline LLC (“Northwest”) filed an application with the Federal Energy Regulatory Commission (“FERC”) requesting a Certificate of Public Convenience and Necessity authorizing Northwest to construct, own and operate the Washington Expansion Project in western Washington. The FERC docket number is CP13-507.

Overview of project

Northwest has been asked by LNG Development Company, LLC (Oregon LNG) to transport an incremental 750,000 dekatherms per day of natural gas to an interconnect with Oregon Pipeline Company, LLC’s proposed Oregon Pipeline near Woodland, Wash. To accommodate this request, Northwest plans to construct the Washington Expansion Project, which will require installation of additional pipeline and compression facilities to the existing Northwest system in the state of Washington.

Pipeline Facilities

The project consists of installing approximately 140 miles of 36-inch diameter pipeline loop in ten different segments along Northwest’s existing pipeline system in the I-5 corridor between Sumas and Woodland.

These segments vary in length from eight miles to over 35 miles. Below is the mileage breakout by county:

County Miles Percentage
Cowlitz 35 25%
Lewis 26 19%
Thurston   8   6%
Pierce 14 10%
King 18 13%
Snohomish 15 11%
Skagit 13   8%
Whatcom 11   8%
Total 140 100%

Compressor Facilities

Compression is also necessary to move gas through the proposed pipeline system. As part of the proposed project, Northwest will upgrade its existing compressor stations at Sumas, Mt. Vernon, Snohomish, Sumner and Chehalis, Wash.

Project Benefits

Construction and operation of the project will create jobs and produce revenues that benefit the state of Washington, which will also benefit the U.S. economy. Local communities would benefit from the property taxes that Northwest would pay during the ongoing operation of the pipeline. These taxes are conservatively estimated to be approximately $13 million per year.

Regulatory Process

Interstate natural gas pipelines are regulated by the Federal Energy Regulatory Commission (FERC). As such, FERC requires pipeline operators to obtain a Certificate of Public Convenience and Necessity, in addition to various state and local permits, before any construction can begin.

As part of its review of the proposed project, FERC staff will prepare an environmental study (the Draft Environmental Impact Statement). During this process, stakeholders will have an opportunity to express their views and have them considered in the review process.

Customer Information

Oregon LNG proposes to build a liquefied natural gas (LNG) terminal near Warrenton, Oregon, where natural gas would be liquefied and transported by ships to Pacific Rim markets. An 86-mile pipeline, named “Oregon Pipeline,” is proposed by Oregon LNG to connect the LNG terminal to the Northwest Pipeline system at the Woodland, Washington interconnect site. More information can be found on Oregon LNG’s website.

Oregon LNG has received authorization from the U.S. Department of Energy (DOE) to export liquefied natural gas to countries that do not have a Free Trade Agreement with the United States. Obtaining approval from the DOE is an important milestone in the process for licensing and LNG export project. Oregon LNG has filed an application with the FERC, which is concurrently undergoing the National Environmental Policy Act review with the Washington Expansion Project. Final approval from the DOE and FERC, as well as other authorizations, is necessary before the project can begin construction.
