Every hear of storage tanks? How do you think tankers are filled today? Straight out of the pipeline? 

Here's the deal. The federal government has authority over inter provincial pipeline approvals. They have approved after the national regulatory assessed the proposed project against the requirements of legislation and after hearing all arguments it ruled in favour of the project with conditions. So, the pipeline will go through. If BC wants to push things too far, Alberta can retaliate and they arguable have more economics weapons than BC has. BC would be hurt very badly. Even if they separate.
