I'd recommend you actually read the laws.
Of course the tax collectors will tell you that you need to pay for all kinds of permits and taxes. Ask them to show you the law requiring you to obtain a permit to have a small wind turbine that is NOT grid tied.
Odds are, the regulations don't apply to you.
I did a quick google search, and found this:
RCW 19.28.091
Licensing -- Exemptions.
(2) No license under the provisions of this chapter shall be required from any utility because of work in connection with the installation, repair, or maintenance of the following:
(c) Lines and wires, together with ancillary apparatus, and equipment, owned by a customer that is an independent power producer who has entered into an agreement for the sale of electricity to a utility and that are used in transmitting electricity from an electrical generating unit located on premises used by such customer to the point of interconnection with the utility's system.
(If the utility doesn't have to have a permit to work on your grid tied windmill, why would you have to have a permit to have a non-grid tied mill?)
(7) This chapter does not require an electrical contractor license if:
(c) the value of the electrical work does not exceed thirty thousand dollars.
A windmill tower isn't a building/structure, so the claim that you need a building permit is bogus. They assumed this is valued at over $30,000, since you asked them questions - and they ONLY deal with projects over $30K.
Just out of curiousity, why would you ask government to direct you to the proper authority for getting permission to do a Constitutionally Protected Natural Right? Liberty and the Pursuit of Happiness are both applicable here.
