    4. Additional information necessary to process the permit application.
  6. Removal. Any wind energy system may be removed as follows:
    1. The system or windmill that is in a state of disrepair and/or has not been operational and in continuous service for a period of one (1) year shall be removed from the property and legally disposed.
    2. All structures and enclosures accessory to the windmill shall also be completely removed from the property and legally disposed.

    4. The applicant shall submit certificates of design compliance obtained by the equipment manufacturers from a certifying organization and any such design shall be certified by qualified engineer.
    5. Prior to construction on any wind energy system, the property owner must acknowledge that responsibility for owning and maintaining the wind energy system and any windmill. The same shall acknowledge that in the event that wind energy system or windmill is abandoned or is in a state of disrepair it shall be the responsibility of the property owner to remove or repair the wind energy system or windmill.
    6. No wind energy system shall commence operation until final inspection is made.
