The strategic gasoline reserve was established in 2014 and presumably filled in late 2014 or early 2015 to stabilize supplies in the N.E. due to weather and other disruptions. It was an Obama directive.
Admittedly, I don't know the particulars of how the reserve was managed or needed to be managed but it would definitely have to be managed, and it would be expensive to do. I do know that stored gasoline is no good after about a year; could maybe stretch it another year with some Stabil- but 10 years? It seems to me that it would basically be useless at that point. Anyway, I'm not convinced that getting rid of it is such a bad idea, especially knowing who set it up in the first place.
