Wind energy facilities; requiring Oklahoma Water Resource Board conduct certain study; effective date.

HB 1263 requires the Oklahoma Water Resources Board to study how wind turbine footings affect the state's aquifers and groundwater resources. The study must analyze physical impacts on aquifer integrity, changes in groundwater flow/quality, cumulative effects in high-wind areas, and mitigation strategies, with input from industry, agriculture, and environmental groups. The Board must submit findings and recommendations to state leaders by December 31, 2026. The bill also includes updated setback requirements for wind facilities near airports, schools, hospitals, and residential areas (increasing to 3 nautical miles for turbines over 500 feet tall), but its primary focus is the mandated groundwater study. This affects wind energy developers and water resource management, with no new regulations beyond the study requirement.
