Here in my area, a few Ethanol plants were proposed 5 or so years ago. Only one got off the "drawing board", because they couldn't get the proper permits, in a timely manner. The one that did get started, was finished this last spring. The corporation that was going to operate it, went under before it was finished. So the "plant" was sold to cover debts. No permits had been issued to manufacture any product. I'm sure once you do more research on you proposal you will find the same thing. Making enough for yourself, no real problems.... Selling product to the public, real BIG problems, with FEDS, STATE, LOCAL Governments and YOUR neighbors. As you will need to rezone part of your "homestead" to manufacturing. If you do decide to go ahead, I wish you all the luck in the world.
