Wind energy facilities; providing setback requirements for wind towers from certain dwellings and property boundaries. Emergency.

SB 429 establishes a minimum 1.5 nautical mile (about 1.7 miles) setback requirement between wind energy facility towers and residential dwellings, as well as adjacent nonparticipating property boundaries. This directly affects wind energy developers who must comply with these distance rules when siting new towers, and protects nearby homeowners from potential noise or visual impacts. The bill also requires developers to obtain FAA "Determination of No Hazard" clearances and resolve Department of Defense compatibility issues before construction. These changes update Oklahoma's existing wind energy regulations to prioritize residential proximity and safety clearances.
