Responding to the D.C. Circuit’s deadline to inform the court how it wishes to proceed in litigation challenging the agency’s listing of two types of per- and polyfluoroalkyl substances (PFAS) as hazardous substances under Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the Environmental Protection Agency (EPA) stood behind its rule. In a September 17, 2025 filing, EPA told the court that the Trump administration had completed its review and would ultimately keep the Biden-era CERCLA final rule in place. The agency also requested that the court remove—i.e. pause—the abeyance placed on the proceedings, so that the lawsuit could move forward and be adjudicated.

On September 11, 2025, the Environmental Protection Agency (EPA) asked the D.C. Circuit to vacate regulations for four types of polyfluoroalkyls (known collectively as “PFAS”) in drinking water. The motion for partial vacatur marks a significant reversal in the agency’s policy, as the EPA had previously vigorously defended legal challenges to the first-of-their-kind standards in federal court for the past two years. See American Water Works Association, et al. v. EPA, case no. 24-1188 and consolidated cases (D.C. Cir. filed June 7, 2024). Just this month, the case was given the green light to proceed, after being held in abeyance (at the request of both parties) so that the Trump administration could determine how it wished to proceed. The change signals a willingness on the part of the administration to act on previously issued non-legally binding announcements of forthcoming changes to Biden-era rules and may also serve as a harbinger for how the new administration will tackle PFAS under other statutes, such as the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

The Supreme Court declined to hear two key federal environmental enforcement cases, effectively leaving in place lower court rulings that allow for broad private citizen enforcement under the Clean Water Act and Clean Air Act. Because of the Court’s denials, citizen plaintiffs remain free to pursue enforcement cases in the absence of governmental enforcement, thus companies remain at risk of being sued by active watchdog citizen groups.

Environmental, Social, and Governance (ESG) considerations are being elevated in corporate, corporate stakeholder, and regulator discourse as never before. Many companies are experiencing ESG pressures for the first time, and indeed they may seem new to entire industries. However, ESG has become an essential institutional investor criteria and will increasingly need to be integrated into the supply and value chains of public and private corporations as financial and other regulators catch up.

Environmental justice is the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies.
