The State of Oregon and Bayer US LLC, parent company of Monsanto and its co-defendants, have reached a $698 million settlement to resolve claims that Monsanto was aware as early as 1937 of the toxic nature of polychlorinated biphenyls (PCBs), but continued to use the PCBs until they were banned in 1977, damaging Oregon waters and wildlife in the process. According to Oregon’s Attorney General, it is the largest environmental damage recovery in Oregon's history.
