This shows no ethanol free in NH, but also seems to indicate that Irving stations sell ethanol free gas. I can't find any verification of this online though.
My google searching indicated that NH has been working on legislation to ban ethanol, but that it won't do any good unless 2 other states sign on because our market is too small for producers to make a special blend.
There was some stirrings up this way about going ethanol free . . . or at least not going with the E-15.
As for Irving gas stations selling ethanol-free . . . I would be surprised to find this since the Irving stations up here all have ethanol.
