The Montana Department of Environmental Quality has announced a $32 million plan to clean up a Superfund site in Evergreen, near Kalispell.
The agency released its decision Monday on the former Kalispell Pole and Timber, Reliance Refining Co. and Yale Oil Corp. facilities, collectively known as the KRY site.
Water and soil contamination was detected at the site in the early 1980s. It includes effects from petroleum storage and the treatment of wood.
The remedy will include sludge removal, soil excavation, chemical oxidation of groundwater and long-term monitoring.
Sandi Olsen with the DEQ says those methods aren’t the cheapest, but are the most effective in dealing with the contamination.
The DEQ has settled with all but one of the defendants in a lawsuit over payment for the site.
