SEATTLE (AP) — A coal-export terminal proposed along the Columbia River in southwest Washington state could have unavoidable, significant impacts on greenhouse gases emissions, vessel traffic and rail safety, according to an environmental review released Friday.

The analysis by the Washington Department of Ecology and Cowlitz County found that greenhouse gas emissions — from facility operations to when the coal is burned in Asia — would increase by 2.5 million metric tons each year when the project is fully running. While measures can be taken to significantly reduce those emissions, the impact “would still be significant and adverse,” the study noted.
