Just a guess: Eco ‘impact assessment’ from EPA.
That is one reason and the other I read was that they have to make sure that this won’t funnel the oil into Mississippi or other states. Of course that made it okay to ruin the wetlands to save the beaches but I do see that the actions of one state can’t make matters worse for another state. Which also highlights why this is a federal issue.
All I know is that it would be nice if the zer0 was a competent leader for once and had the best interest of his constituents in mind instead of furthering his marxist agenda.
