CHEYENNE, Wyo. — After a three-and-a-half-year process, the Office of Surface Mining Reclamation and Enforcement has given the green light to Wyoming’s solution for disposing of decommissioned wind turbine blades and towers. The Final Rule Notice allows for the inert materials to be repurposed as backfill in surface coal mines, marking a significant step in addressing the growing challenge of wind energy waste.

“For Wyoming and the nation, this is an important step in finding solutions to the challenges within the diverse energy mix. We are very proud to be a part of this answer both in providing energy and protecting our environment,” said Todd Parfitt, director of the Wyoming Department of Environmental Quality.

The journey began in 2020 with Wyoming House Bill 0129, which paved the way for the state to develop specific reclamation standards for using retired wind turbine blades and towers in surface coal mines. The legislation addressed the needs of both the wind industry, which was seeking environmentally friendly disposal options, and the coal industry, which requires substantial amounts of backfill for mine reclamation.

“Rather than sit on the sideline, Wyoming, once again, is leading the nation in efforts to find solutions to challenging issues related to providing for energy needs by creating a bridge that benefits both the coal and alternative energy industries,” said Kyle Wendtland, director of fossil fuel development at the Wyoming Energy Authority.

The new rule requires that only inert base materials from wind turbine blades and towers be used for backfill. Nacelles, mechanical electrical and other components must be removed prior to disposal. The approved backfill locations must meet specific criteria, including being situated a safe distance from groundwater resources. The rule also mandates ongoing groundwater monitoring and proper drainage to ensure environmental protection.

“We are thrilled to be leading the way with this innovative solution, and are pleased that the OSMRE has issued the final rule notice,” said Brandi O’Brien, WDEQ/LQD administrator. “This will positively impact the energy sector in Wyoming, while continuing to protect the environment.”

The final rule, published today in the Federal Register, will take effect Feb. 12, 2025.
