WASHINGTON (AP) — The Trump administration has reached a multi-state settlement with chemical giant Chemours Co. over years-long, illegal discharges of synthetic “forever chemicals” used to make products resistant to water, grease and stains. The settlement is the first by the federal government to resolve enforcement claims against a manufacturer of harmful chemicals known as PFAS.The Associated Press learned details of the settlement ahead of an announcement expected later Wednesday. Under the agreement, Chemours will pay a civil penalty of $22.5 million for alleged violations and spend $90 million over 15 years to mitigate PFAS discharges in three states: West Virginia, North Carolina and New Jersey. Chemours, a spin-off of chemical maker DuPont, also agreed to install PFAS pollution controls for and surface water discharges and air emissions at a West Virginia facility; supply clean drinking water to communities near its West Virginia and New Jersey sites; and implement controls to reduce releases of PFAS and other toxic chemicals from its facility in North Carolina.

Combined, the penalties and relief programs are estimated to cost about $450 million, the Justice Department said.
