Divested Neoprene Facility, La Place, Louisiana - EPA Compliance Inspection

In 2016, the U.S. Environmental Protection Agency (“EPA”), conducted a focused compliance investigation at the Denka Performance Elastomer LLC (“Denka”) neoprene manufacturing facility in La Place, Louisiana. EIDP sold the neoprene business, including this manufacturing facility, to Denka in the fourth quarter of 2015. Subsequent to this inspection, the EPA, the U.S. Department of Justice (“DOJ”), the Louisiana Department of Environmental Quality (“Louisiana DEQ”), EIDP and Denka began discussions in the spring of 2017 relating to the inspection conclusions and allegations of noncompliance arising under the Clean Air Act, including leak detection and repair.

For many years, Denka, EIDP, and DuPont, as the current landlord, continued to work with the EPA, DOJ and Louisiana DEQ to achieve an amicable resolution. On February 28, 2023, the United States Government, on behalf of the EPA, filed a lawsuit against Denka in Federal Court in Louisiana claiming that Denka’s continued chloroprene emissions constitute an imminent damage to the public. A DuPont subsidiary was also named as a defendant simply as the landlord/property owner. The lawsuit sought injunctive relief requiring Denka to eliminate the alleged imminent and substantial endangerment posed by its chloroprene emissions from the facility. On March 7, 2025, the EPA and DOJ, acting on direction from the current Presidential administration, dismissed the lawsuit.

New Jersey PFAS Directive

This matter is resolved by the proposed Judicial Consent Order with the State of New Jersey reached in August 2025. See Note 14 to the interim Consolidated Financial Statements for more information.
