VANCOUVER, B.C. — The governor of Washington says his state is “allied” with British Columbia in questioning whether the Trans Mountain pipeline should be expanded. Gov. Jay Inslee says the project poses a threat to waters off the West Coast, which Washington residents view as a treasure. He says the state is looking at marine safety laws that would help mitigate the impact of a tanker spill. Inslee is in Vancouver Friday for a meeting with British Columbia Premier John Horgan and officials from Oregon and California, which make up the Pacific Coast Collaborative. Inslee says residents in his state recently rejected proposals for both coal and oil ports.
