U.S. Supreme Court: Superfund suits in Montana can press EPA for cleanup

MISSOULA — Some Anaconda area landowners still have a chance to force the Atlantic Richfield Co. remove more arsenic from their property.

On Monday, the U.S. Supreme Court issued a unanimous decision that Montana’s courts and laws can play a role in federal Superfund decisions. However, the court also decided – not quite unanimously – that residents within a Superfund site have to get federal approval if they want to get rid of more contamination than the Environmental Protection Agency tolerates.
