On May 29, 2025, the Supreme Court issued its long-awaited decision in Seven County Infrastructure Coalition v. Eagle County. In a five-justice majority opinion written by Justice Kavanaugh, the Court held that the National Environmental Policy Act (“NEPA”) does not require review of the environmental impacts of “upstream” or “downstream” related projects, and reiterated: “The bedrock principle of judicial review in NEPA cases can be stated in a word: Deference.”[1] This decision comes as the federal government works to expedite what over the years have become lengthy NEPA review processes, and not long after the White House Council on Environmental Quality rescinded its NEPA regulations.

On May 14, 2025, the Environmental Protection Agency (“EPA”) announced that it will keep the current National Primary Drinking Water Regulations (“NPDWR”) for perfluorooctanoic acid (“PFOA”) and perfluorooctane sulfonic acid (“PFOS”) under the Safe Drinking Water Act (“SDWA”), while extending the compliance deadline from 2029 to 2031. EPA further announced it plans to rescind requirements in those regulations applicable to other PFAS and mixtures of certain PFAS in drinking water. The NPDWR consists of legally enforceable primary standards and treatment techniques that apply to public water systems and guide EPA’s enforcement of the SDWA. This announcement follows EPA’s April 28, 2025 press release outlining its priorities for PFAS enforcement, which included 21 actions EPA intends to take to address PFAS and “engage with Congress and industry to establish a clear liability framework that ensures the polluter pays and passive receivers are protected.”

Following a directive from President Trump,[1] and in the wake of two court decisions concluding the Council on Environmental Quality (“CEQ”) had no authority to promulgate them in the first place, CEQ’s National Environmental Policy Act (“NEPA”) regulations are being removed from the Code of Federal Regulations.
