Background

The Northwest Pipeline system is a primary artery for the transmission of natural gas to the Pacific Northwest and Intermountain Region. It began as a 1,500-mile pipeline and has since expanded into a 4,000-mile bi-directional transmission system crossing the states of Washington, Oregon, Idaho, Wyoming, Utah and Colorado. Northwest’s bi-directional system provides access to British Columbia, Alberta, Rocky Mountain and San Juan Basin gas supplies. There are several expansion projects currently planned, including into Mollala and Jordan Cove, Oregon, and Plymouth, Washington. [1] As of 2017, there is also a lateral expansion planned into Seattle, Washington. [5]
