Final environmental report issued for Jordan Cove project in Oregon

Free Read

US energy regulators have completed the Final Environmental Impact Statement (EIS) for the proposed Jordan Cove liquefied natural project being developed by Pembina Pipeline Corp. of Canada at Coos Bay in the northwest state of Oregon. 

The EIS was issued by the Federal Energy Regulatory Commission and concluded that while constructing and operating the project would result in “temporary, long-term, and permanent impacts” on the environment, many would not be significant and would be reduced to less than significant levels with mitigation measures.

“However, some of these impacts would be adverse and significant. Specifically, the final EIS concludes that constructing the project would temporarily, but significantly impact housing in Coos Bay,” said the FERC report.

The regulator also stated that constructing and operating the project would “permanently and significantly impact” the visual character of Coos Bay and the surrounding area.

“The project could have a significant impact on the Southwest Oregon Regional Airport operations and further, constructing and operating the project is likely to adversely affect 18 federally-listed or proposed threatened and endangered species,” it added.

The liquefaction plant and other facilities are planned for a 200-acre site and comprise five small-scale Trains each with 1.5 million tonnes per annum of output for a total of 7.8 MTPA.

The Jordan Cove venture’s other facilities would include two full-containment LNG storage tanks with total capacity of 320,000 cubic metres, gas treating facilities, an export jetty and access to more than 25 billion cubic feet per day of gas supply from Western Canada and the US Rockies.

The US Coast Guard has already issued a Letter of Recommendation indicating that the Coos Bay Federal Navigation Channel would be considered suitable for the LNG marine traffic associated with the project.

The plant would be visited by about 120 LNG carriers per year and Pembina has confirmed that it had signed preliminary accords with Jera Co Inc. and Itochu Corp. of Japan for the supply of LNG.

The project’s affiliated Pacific Connector pipeline would be around 230 miles in length and have a 36-inch diameter with capacity to transport up to 1.2 billion cubic feet of natural gas per day.

The pipeline would originate at interconnections with existing pipeline systems in Klamath County, Oregon, and would span parts of Klamath, Jackson, Douglas, and Coos Counties before connecting with the export plant.
