I don't know about the permits...I personally would never get my name on a "watch list" by applying for a permit that they will never give me.
Don't advertise, but if anybody asks, make sure to inform them that you are making it for a boat, tractor, ATV, or generator. If anybody suspects that you are using it for a vehicle that is registered for road use, there is a big fine for failure to pay road taxes (usually part of the fuel price). You can usually add 20% ethanol to the gasoline (for a generator, of course) without eroding the rubber seals in the fuel system. If you want to try a higher concentration, find or make Viton synthetic seals (cut a sheet of Viton with a razor to match existing gaskets).
"off-road" Diesel is dyed red and costs less. It is used for the aforementioned devices. Clear diesel has road taxes added into the price. On occasion, a farmer with a Diesel pick-up truck is fined several thousand dollars for getting caught putting the cheaper red diesel in his truck.
Carbohydrates (potatoes, corn, sugar-beets, etc) can be converted to a type of sugar by enzymes (you can buy these from an internet supplier) mash them up, add a little water and the enzymes. Adding Yeast will then convert sugar into alcohol. You warm the sealed mash-pot just enough to evaporate the alcohol, a tube coming off the lid makes a U-turn and once its headed down, the tube is cooled by wind or water, and the alcohol drips out with some warm water vapor. Use copper or stainless steel, don't use any solder in the joints.
The first few minutes the mash is warming it produces methanol, do not ever drink this, save it for fuel only, it will kill you.
Occasionally burn a few drops, and when the flame color changes, its producing ethanol. To use as a consumable pain-killer and a wound disinfectant, you should triple-distill it and filter it through charcoal, which absorbs most of the chemical byproducts.
