Washington’s governor on Monday put a presumed end to a proposed oil-by-rail export terminal at the Port of Vancouver, notifying state regulators that he agreed with their unanimous decision to reject the controversial project.

The state’s Energy Facility Site Evaluation Council voted in November to recommend that Gov. Jay Inslee deny the Tesoro-Savage proposal. In a letter announcing his decision, Inslee said he found ample support in the record for the council’s decision that the project was wrong for the proposed site, including risks posed by a large earthquake, an oil spill or an explosion or fire at the facility.

Inslee said the facility posed potentially catastrophic risks to the public and there was no way to mitigate the impacts that that an oil spill would have on water quality, wetlands, fish and wildlife.

“The Council found that emergency responders are unlikely to be able to successfully respond to a major incident at the facility,” Inslee wrote.

Vancouver Energy, a joint venture of the Tesoro Corp, now known as Andeavor, and Savage Co.s, has 30 days to appeal the governor’s decision in Thurston County Superior Court. A spokesman for Savage said the company would have a statement, but had not issued one yet.

The companies had proposed spending $210 million on a terminal at Port of Vancouver to transfer 360,000 barrels a day of Bakken crude from trains onto marine vessels for shipment to West Coast refineries. Supporters pointed to the jobs and property taxes that would be generated by the facility.

Dan Serres, conservation director for the advocacy group Columbia Riverkeeper, said the proposal attracted unprecedented opposition from a cross-section of businesses, environmental groups and citizens. And while the company could appeal the decision, Serres said they’d be doing so without a lease as the Port of Vancouver has already signaled its intent to seek other options as of March 31.

“The idea of putting five loaded oil trains a day down the Columbia River Gorge was irresponsible, and after Mosier, that became clear,” said Serres, referring to the fiery derailment of an oil train near the town of Mosier in June 2016.  “We’re just overjoyed to see them go away. This one’s over.”
