The gasoline I buy is trucked from Anch to Fairbanks. It is slightly more expensive than local refinery gasoline, but only because it is a full service station rather than a gasoline island at the dept store or 7-Eleven.
The point here is that product that moves by pipe is and will always be X amount cheaper than product that does not or can not. Ethanol falls into the second category; transportation of ethanol AK will be/would be/is just building in another layer of cost to the consumer.
This is readily demonstrated by observation. RBOB ('new' ethanol-blended gasoline) is trading between 12 and 20 cents premium to RFG II ('regular' unleaded) in the same month, basis NY harbor. The differential for, say, Anchorage must be higher still.
You Alaskans are well out of this boondoggle idiocy. I hope it stays that way for you.
