New government regulations for the National Environmental Policy Act (NEPA) enacted by federal agencies, influenced by Executive Order 14154 and the Supreme Court's judgment in the Seven County case.
The National Environmental Policy Act (NEPA), enacted in 1970, has long been a cornerstone of federal decision-making, ensuring that potential environmental impacts are considered in major projects. However, recent changes, primarily due to President Trump's Executive Order (EO) 14154 in 2025 and the Supreme Court’s decision in Seven County Infrastructure Coalition v. Eagle County Colorado (2025), are reshaping NEPA processes, with a focus on expediting reviews and reducing regulatory overlap, but not without controversy.
The Council on Environmental Quality (CEQ), which coordinated NEPA implementation across all federal agencies, has lost its binding regulatory authority, following EO 14154 and rulings from two federal courts in 2024 and 2025 that CEQ lacks authority to issue regulations binding on federal agencies. This shift introduces legal uncertainty about NEPA's regulatory framework.
Federal agencies, including the Department of Transportation (DOT), Department of Defense, Energy, Interior, and others, have issued revised NEPA procedures aimed at expediting reviews and cutting red tape. For instance, DOT has unified multiple NEPA protocols into a single framework and narrowed the scope of actions subject to review. However, these changes have not come without litigation risks.
One such risk is the heterogeneous agency procedures without a uniform regulatory baseline, which may generate challenges to procedural adequacy and consistency across agencies. Additionally, agencies may still face lawsuits over the scope of indirect or cumulative environmental effects considered and NEPA document adequacy. Public and stakeholder engagement may also be reduced, potentially triggering legal challenges over transparency and meaningful participation.
The Supreme Court’s Seven County decision reduces agencies’ obligation to review effects of separate projects not under their control, clarifying and limiting the scope of environmental impact statements (EIS) efforts. This may shorten reviews and reduce litigation regarding broad cumulative impacts. However, it may also complicate matters by creating inconsistencies in the level of review across different projects.
New legislative mandates and executive orders targeting specific sectors, such as nuclear energy, impose deadlines and promote streamlined processes, potentially accelerating project approvals. Yet, these compressed timelines also concentrate disputes, increasing the likelihood of litigation and delays.
In summary, EO 14154 and the Seven County ruling collectively reshape NEPA processes towards faster environmental reviews with reduced regulatory overlap and scaled-back impact analysis scope. However, the loss of CEQ’s binding regulatory authority, heterogeneous agency procedures, and concerns about transparency create ongoing litigation risks that could delay or complicate project development despite official efforts to streamline. Project proponents should closely monitor agency rulemakings and court decisions to navigate these evolving risks.
