Oklahoma Smelter Revises Fluoride Limits | Tulsa News

Oklahoma Primary Aluminum just slashed its proposed fluoride emissions limit by 37% in a revised permit application, dropping it from 1.02 to 0.64 pounds per ton of aluminum — still under review. The company claims the new number reflects updated engineering and is lower than most international standards, with actual daily emissions expected to be even less. But nearby residents remain skeptical, and experts warn fluoride isn’t the only concern — sulfur dioxide and greenhouse gases are also part of the equation. The firm plans to run air dispersion modeling to assess impacts on people, animals, and plants, working with state regulators to prove safety. With no construction permit yet and public comment still ahead, the final decision remains pending. Listen in comfort:Get a discount on a Soli Pillow: http://solipillow.com/discount/dnn.
