FERC to issue enviro review on Oregon LNG project in February 2016

The Federal Energy Regulatory Commission in an April 17 notice laid out the environmental review schedule on applications for approval of a liquefied natural gas (LNG) import/export project in Oregon and supporting gas pipeline projects.

In 2008, LNG Development Co. LLC filed an application to site, construct, and operate an LNG import terminal in Warrenton, Oregon. On the same day, Oregon Pipeline Co. LLC filed an application requesting a Certificate of Public Convenience and Necessity to construct and operate a send-out pipeline from the proposed LNG import terminal to the Molalla Gate Station in Clackamas County, Oregon. Combined, the proposals are referred to as the “Oregon LNG Terminal and Pipeline Project.”

In June 2013 LNG Development and Oregon Pipeline (collectively referred to as Oregon LNG) amended their pending applications to add LNG export capabilities and revise the pipeline route.

  • The terminal would have the capacity to liquefy up to 1.3 billion cubic feet per day of natural gas for export or regasify 0.5 billion cubic feet per day of natural gas for import.
  • The current proposed pipeline would consist of an 86.8-mile-long, 36-inch-diameter bidirectional pipeline from the terminal to an interconnect with the interstate transmission system of Northwest Pipeline LLC near Woodland, Washington.

In June 2013, Northwest filed an application to expand the capacity of its existing natural gas transmission facilities between Woodland and Sumas, Washington. Northwest would accomplish the expansion by constructing and operating 140.6 miles of 36-inch-diameter pipeline loop in 10 noncontiguous segments and adding compression facilities at five existing compressor stations.

Northwest’s Washington Expansion Project and the Oregon LNG Terminal and Pipeline Project are connected actions, and the FERC will evaluate all project proposals in one environmental impact statement (EIS). The issuance of the notice of availability of the final EIS is due on Feb. 12, 2016, with a May 12, 2016, decision deadline.

Oregon LNG’s proposed bidirectional LNG terminal would be located on the East Bank Skipanon Peninsula near the confluence of the Skipanon and Columbia Rivers in Warrenton, Clatsop County, Oregon. The terminal would include a marine terminal with a ship berth for LNG carrier; two full-containment storage tanks, each designed to store 160,000 cubic meters of LNG; natural gas pretreatment facilities; two liquefaction process trains, regasification facilities, and other related support structures and systems. The pipeline facilities would consist of an 86.8-mile-long, 36-inch-diameter bidirectional pipeline from the terminal through Clatsop, Tillamook, and Columbia Counties in Oregon and Cowlitz County in Washington. A single 40-MW, 48,000-horsepower (hp) electrically driven gas compressor station would be constructed in Columbia County, Oregon.

Northwest’s project would expand the capacity of its existing pipeline between Sumas and Woodland, Washington, by 750,000 dekatherms per day. The new facilities for the Washington Expansion Project would include: about 140 miles of 36-inch-diameter pipeline loop along Northwest’s existing pipeline in 10 segments; and an additional 96,000 hp of compression at five existing compressor stations. Upon completion, the Northwest Pipeline would be capable of delivering about 1.25 billion cubic feet per day of gas to the proposed Oregon LNG pipeline at the interconnect in Woodland, Washington. The 10 segments of new pipeline loop would be noncontiguous and traverse through Whatcom, Skagit, Snohomish, King, Pierce, Thurston, Lewis, and Cowlitz counties.
