Atlantic Richfield Company V. Montana Second Judicial District Court, Molly Kelly

Public Land & Resources Law Review

Landowners in Opportunity, Montana sought restoration damages from ARCO, Anaconda Copper Mining Company’s successor, to their property from over a century of processing ore at the Anaconda Smelter. ARCO argued that CERCLA preempted and barred any claim for restoration damages. The Montana Supreme Court held: landowners could bring their state common law claims seeking restoration damages; the state district court had subject matter jurisdiction; and landowners’ proposed restoration fund did not challenge EPA’s selected remedy under CERCLA.
