Superfund list

The U.S. Environmental Protection Agency has reached a $57.6 million cleanup agreement with Columbia Falls Aluminum Company to address pollution from decades of aluminum smelting at its Montana site. The agreement outlines mitigation of toxic byproducts like arsenic, fluoride, and cyanide, with the site previously added to the Superfund list in 2016. The cleanup plan includes capping waste to prevent soil and water contamination, though the 647-page agreement requires a 30-day public comment period and court review before finalization.
