2018-00328. Northwest Pipeline LLC; Notice of Schedule for Environmental Review of the North Seattle Lateral Upgrade Project  

  • Start Preamble

    On May 11, 2017, Northwest Pipeline LLC (Northwest) filed an application with the Federal Energy Regulatory Commission (Commission or FERC) in docket number CP17-441-000 requesting a Certificate of Public Convenience and Necessity pursuant to Sections 7(b) and 7(c) of the Natural Gas Act to construct and operate certain natural gas pipeline facilities. The proposed project is known as the North Seattle Lateral Upgrade Project (Project), and would replace an existing 8-inch-diameter pipeline with a 20-inch-diameter pipeline, increasing the design capacity on Northwest's system to serve Puget Sound Energy.

    On October 23, 2017, Northwest filed an amendment to its application, and on November 2, 2017, the Commission the issued a Notice of Amendment to the Application for the revised Project. Among other things, that notice alerted agencies issuing federal authorizations of the requirement to complete all necessary reviews and to reach a final decision on a request for a federal authorization within 90 days of the date of issuance of the Commission staff's Environmental Assessment (EA) for the Project. This instant notice identifies the FERC staff's planned schedule for the completion of the EA for the Project.

    Schedule for Environmental Review

    Issuance of EA: February 12, 2018.

    90-day Federal Authorization Decision Deadline: May 13, 2018.

    If a schedule change becomes necessary, additional notice will be provided so that the relevant agencies are kept informed of the Project's progress.

    Project Description

    Northwest proposes to remove approximately 5.8 miles of the 8-inch-diameter North Seattle Lateral pipeline in Snohomish County, Washington and replace it with 20-inch-diameter pipeline, primarily in the same trench. The North Seattle Lateral Upgrade Project would consist of the following facilities:

    • Replace 5.8-miles of 8-inch-diameter pipeline with 20-inch-diameter pipeline;
    • rebuild the existing North Seattle/Everett meter station in order to accommodate the increased delivery capacity of the North Seattle Lateral;
    • relocate an existing 8-inch pig launcher and a 20-inch pig receiver; [1] and
    • replace an existing 8-inch mainline valve with a 20-inch valve.


    On June 21, 2017, the FERC issued a Notice of Intent to Prepare an Environmental Assessment for the Proposed North Seattle Lateral Upgrade Project, Request for Comments on Environmental Issues, and Notice of Public Scoping Session (NOI) in Docket No. CP17-441-000. The NOI was mailed to 409 parties, including affected landowners; federal, state, and local government representatives and agencies; elected officials; environmental and public interest groups; Native American tribes; other interested parties; and local libraries. We also held a public scoping comment session in the Project area on July 13, 2017.

    The primary issues raised by commenters were impacts on residences (including noise, dust, drainage, and vegetation clearing), biological and water resources impacts, alternative routings for crossing the Fritch Mill property, pipeline safety, and impacts on adjacent utility easements and infrastructure.

    On October 23, 2017 Northwest amended its application, reducing the Project's incremental firm capacity from 196,311 to 159,299 dekatherms per day; reducing the length of the replacement 20-inch-diameter pipeline by about 1 mile; locating the replacement pig launcher/receiver at milepost 7.76; and changing the pipeline route between mileposts 2.1 and 2.2 so as to divert its pipeline system around the Fritch Mill. Accordingly, on November 21, 2017 we issued a Supplemental Notice of Intent to Prepare an Environmental Assessment for the Amended North Seattle Lateral Upgrade Project and Request for Comments on Environmental Issues (NOI) in Docket No. CP17-441-001. The Supplemental NOI was mailed to 312 parties, including affected landowners; federal, state, and local government representatives and agencies; elected officials; environmental and public interest groups; Native American tribes; other interested parties; and local libraries.Start Printed Page 1347

    Comments on the Supplemental NOI concerned the need for relocating the pipeline off the existing right-of-way; impacts to springs, wetlands, and mature forest from the newly routed segment, and alternatives.
