[Breaking News] Chemours, DuPont, and Corteva settle New Jersey’s 'forever chemical' PFAS claims for $875 million!

The Chemours Company, DuPont de Nemours, Inc., and Corteva, Inc. today announced a comprehensive settlement resolving all pending environmental and other claims brought by the State of New Jersey in various litigation matters and under other state directives. The settlement resolves all legacy contamination claims associated with the companies’ current and former operating sites—including Chambers Works, Parlin, Pompton Lakes, and Repauno—as well as statewide PFAS contamination claims unrelated to those sites, including contamination arising from the use of aqueous film-forming foam (AFFF). The total settlement amount is $875 million, payable over 25 years, beginning 30 days after the effective date of the proposed Judicial Consent Order (“JCO”), which shall not be earlier than January 1, 2026. Of the total settlement amount, $16.5 million is allocated to alleged PFAS contamination unrelated to the companies’ operating sites—including $4.125 million specifically attributable to AFFF. Applying the discount rate for prepaid settlement amounts specified in the JCO, the pre-tax present value of the total settlement is approximately $500 million. Pursuant to a Memorandum of Understanding (“MOU”) signed by the parties in January 2021, Chemours will bear 50% of the settlement amount—or approximately $250 million in present value—DuPont will bear 35.5%, or approximately $177 million in present value—and Corteva will bear the remaining 14.5%, or approximately $72 million in present value. The settlement agreement also establishes a process for determining the amounts and initial scopes of funding sources (“RFS”) for remediation at the four current and former operating sites, along with other mechanisms to ensure future site remediation. The RFS will be secured by surety bonds or similar instruments. Additionally, DuPont and Corteva will establish a reserve fund, capped at $475 million, allocated according to their respective cost-sharing percentages, and secured by surety bonds or similar instruments. This reserve fund serves as an independent, subordinate financial guarantee to the RFS. It may only be drawn upon under limited conditions detailed in the settlement agreement. Neither the RFS nor the reserve fund represents new cash outlays by the two companies, beyond ongoing costs to maintain the surety bonds or similar supporting instruments. The settlement terms are set forth in the proposed Judicial Consent Order (“JCO”), which remains subject to notice and comment under New Jersey law, as well as final court approval. Furthermore, following approval of the JCO, DuPont and Corteva will purchase from Chemours, for $150 million, Chemours’ rights to certain insurance recoveries related to PFAS claims.
