Wind turbine blades-onsite disposal required.

HB 89 requires wind energy facilities in Wyoming to dispose of decommissioned turbine blades and towers on the site where they operated, rather than sending them to municipal landfills. The bill prohibits landfill disposal of these materials, mandates burying only base materials (not mechanical parts), and specifies minimum depth requirements near aquifers. Exceptions include on-site recycling, removal of non-base materials, and disposal at surface coal mining sites. The rulemaking requirements and effective date (July 1, 2025) apply to new permits issued after that date.
