On April 20, 2020, the U.S. Supreme Court reversed a Montana Supreme Court ruling that allowed private landowners to impede the EPA’s efforts to clean a large hazardous-waste site. Federal law blocks states or private parties from interfering with the EPA-directed cleanup of such a site. The Montana high court nonetheless affirmed an order allowing landowners to seek money for a cleanup plan that conflicts with an EPA-directed cleanup plan. The U.S. Supreme Court agreed with the petitioner—and with an amicus brief filed by WLF—that the landowners’ suit could not proceed without EPA approval.
