“I don’t think they cab do it. It takes Presidential approval and I don’t believe they can override his disapproval.”
I was kind of wondering about that. There are thousands of pipelines in the US. Was presidential approval needed for all of them?
When crossing the US border the State Department must approve. Effectively, that requires Presidential Approval.
No...It’s only because another nation is involved, i.e., the line is crossing the USA/Canada border.
