– A federal appeals court has ruled that BP’s Atlantic Richfield Co. must pay more than $10 million to clean up a Superfund site in Montana, the Wall Street Journal reports. A lower court had found that ARCO and its parent company, BP’s Asarco, had set aside $111.4 million for the cleanup, but a three-judge panel of the 9th US Circuit Court of Appeals reduced that to $61.4 million. Asarco is a former mining company.
