Of course, anything to deny pipeline space to crude from the Bakken/Three Forks as well, even though much of that moves by rail.
I'm surprised this has not already implemented as Fed involvement in permitting is limited largely to river crossings, which is an engineering technology related permit by the Corps of Engineers. Note the rapid implementation of the southern leg of the XL from Cushing to the Gulf Coast. Canada's decision to pull the trigger on their west coast pipeline will take political gamesmanship off the table on delaying the Northern leg of the XL implemented with respect to Bakken connection.
We now what motivates this administration!
