On January 15, 2026, the Environmental Protection Agency (EPA) published the long-awaited proposed rule Updating the Water Quality Certification Regulations (Proposed Rule), which, if adopted, would largely reinstate the previous Trump administration’s 2020 Clean Water Act Section 401 Certification Rule (2020 Rule). EPA’s proposal seeks to limit the scope of state-issued water quality certifications (WQCs) under Section 401 of the Clean Water Act (CWA) to water quality impacts associated with discharges authorized by federal agency actions. The Proposed Rule also addresses concerns raised by applicants for federal licenses and permits (including for hydroelectric projects, natural gas pipelines, and other energy and infrastructure projects) that certain states have overstepped their Section 401 authority to impose onerous terms and conditions unrelated to water quality and artificially extended the statutory time limits for issuing WQCs.
One-Track Mind: Unanimous SCOTUS Decision on Rail Line Approval Further Narrows Scope of NEPA
On May 29, the Supreme Court issued a unanimous opinion in Seven County Infrastructure Coalition v. Eagle County, Colorado that dramatically changes the way courts scrutinize federal agencies’ environmental reviews under the National Environmental Policy Act (NEPA). Justice Brett Kavanaugh, writing for a five-justice conservative majority (with Justice Neil Gorsuch abstaining), held that (a) courts must afford federal agencies “substantial judicial deference” regarding both the scope and contents of their environmental analyses; and (b) courts do not need to consider the effects of the action to the extent they are “separate in time or place” from the proposed project. The ruling gives federal agencies permission to greatly streamline their NEPA analyses at a time when those agencies are rapidly being drained of their resources and facing increasing pressure to expedite lengthy permitting processes.
Council on Environmental Quality Proposes Long-Awaited NEPA Regulations Overhaul
On January 10, 2020, the Council on Environmental Quality (CEQ) published the long-awaited proposed rule to amend its regulations implementing the National Environmental Policy Act of 1969 (NEPA). The statute, sometimes pejoratively referred to as a “paper-tiger,” requires a federal agency to take a hard look at the environmental impacts
