EPA's "Compliance First" Directive Creates Pathway For Preemption Of Citizen Suits

On December 5, 2025, the U.S. Environmental Protection Agency's (EPA) Office of Enforcement and Compliance Assurance (OECA) published an internal memorandum formally adopting a new "compliance first" enforcement approach for all OECA staff. The memorandum directs EPA personnel to prioritize compliance and the timely resolution of matters rather than engage in protracted investigations and disputes. Among the various directives contained in the memorandum is language specifically targeting "citizen suit litigation" or lawsuits initiated by private parties against potentially responsible parties for violations of environmental statutes. These private causes of action are established by federal statutes such as the Clean Water Act, Clean Air Act, Resource Conservation and Recovery Act, and Comprehensive Environmental Response, Compensation, and Liability Act, as well as state statutes such as New Jersey's Environmental Rights Act.
