OK SB2

Wind turbine towers in "affected counties" (population density >8.5 persons/sq mile and average wind speed <9.5 mph) must be located at least 1.5 times the tip height from property lines and at least 0.5 nautical miles from dwelling structures

Property owners may waive setback requirements, and executing a lease with a wind energy company for tower placement constitutes an automatic waiver

County voters can modify or eliminate setback limitations through a referendum initiated by county commissioners or by petition signed by 10% of voters from the last presidential election, with votes allowed only once every 5 years

Wind energy companies have 4 years from securing grid interconnection rights to begin substantial construction; projects with 3+ years of existing interconnection rights get 12 months from the effective date

Oklahoma Corporation Commission must maintain a public database showing setback provision status for each county, including applicable expiration dates
