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.
US Army Corps of Engineers Finalizes 2026 Nationwide Permit Package
On January 8, 2026, the U.S. Army Corps of Engineers finalized 57 Nationwide Permits first proposed in June of last year. Nationwide Permits (NWPs) are streamlined federal permits for activities that affect waters of the United States, ranging from routine development and infrastructure projects to major projects. In this action
Navigating a New WOTUS Definition: Agencies Redefine the Line
Over the past decade, the definition of “waters of the United States” (WOTUS) has shifted repeatedly, creating uncertainty for permitting and project planning. Building on the Supreme Court’s Sackett v. EPA decision, the EPA and the U.S. Army Corps of Engineers (together, the agencies) announced a proposal this week to further refine which water features qualify as WOTUS by narrowing key definitions and codifying — and expanding — exclusions. The proposal would apply across all Clean Water Act (CWA) programs that rely on WOTUS, including permitting under Sections 404 and 402, water quality certifications under Section 401, and Total Maximum Daily Loads (TMDLs) for impaired waters under Section 303. The proposal is directionally deregulatory, meaning fewer waters are likely to be considered federally jurisdictional and therefore regulated. The new definition was published in the Federal Register on Thursday, marking the start of a 45-day public comment period through January 5, 2026. The public comment page can be accessed here.
Illegal Eagles: DOI Sinks Its Talons Even Deeper Into Wind Energy
The frenetic pace of anti-renewable actions from the U.S. Department of the Interior (DOI) has continued into this week with the issuance of a new memorandum from Greg Wischer, deputy chief of staff for policy, directing the U.S. Fish and Wildlife Service (FWS) to ratchet up enforcement of the Bald and Golden Eagle Protection Act (BGEPA) against wind energy projects, and to scrutinize the eagle permit program that the FWS adopted in 2024 after many years of development.
Déjà vu? FWS Solicits Feedback to Update Section 10(a) of the ESA
On Monday, June 9, the U.S. Fish and Wildlife Service (FWS) opened a short, 30-day public comment period soliciting information and comments to, “improve the overall efficiency and effectiveness” of Section 10(a) take permitting under the Endangered Species Act (ESA). If it seems like Section 10(a) just underwent a comment period not too long ago, that’s because it did. In 2023, under the Biden Administration, FWS solicited comments on proposed revisions to the regulations implementing that section, which were finalized last April. Now, the Trump Administration is seeking suggestions on how to further revise its ESA permitting rules.
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.
