The state panel examining a proposal to build a rail-to-marine oil transfer terminal in Vancouver agreed Tuesday to extend to Nov. 1 of this year the deadline for completing the review and for making a recommendation to Gov. Jay Inslee.

The move by the Energy Facility Site Evaluation Council, which was expected, marks the second time it has extended the deadline to wrap up a knotty review that includes an environmental impact analysis, public comment process and judicial hearings. Tesoro Corp., a petroleum refiner, and Savage Companies, a transportation company, want to construct the oil terminal at the Port of Vancouver. It would be the largest such operation in the U.S., receiving an average 360,000 barrels of crude per day.

By law, the evaluation council must reach a recommendation within 12 months of receiving an application for a large energy project. But the law also allows timeline extensions, which are not unusual given the size and complexity of proposals.

Tesoro and Savage, in partnership as Vancouver Energy, filed their permit application on Aug. 29, 2013. As the application’s review approached one year, the evaluation council agreed to extend the deadline to March 2.

But that target date also proved unrealistic. Responding to a new timeline suggested by Tesoro-Savage, the evaluation council voted unanimously Tuesday to move the deadline to Nov. 1.
