Attorneys say they reached a $375 million settlement late Wednesday, May 18, 2016, in a legal battle between the operators of the former nuclear weapons plant outside Denver and thousands of homeowners who said plutonium releases from the plant hurt their property values.

Property owners near the former Rocky Flats nuclear weapons facility have finally settled a long legal battle over contamination, agreeing to a $375 million settlement. 

Fifteen thousand property owners near Arvada and Westminster sued the operators of the nuclear weapons plant in 1990, alleging wide-spread plutonium contamination.  Now, the sides have come to an agreement, according to an attorney for the plaintiffs.

If approved by a judge, the settlement will be paid out by the companies that ran the plant -- Dow Chemical and Rockwell International, now owned by Boeing.  It’s not clear how much the federal government is on the hook for; details of the settlement were not immediately available.   

Rocky Flats opened after World War II. For more than three decades it produced nuclear weapon components. It’s now a wildlife refuge.
