Why Does This Decision Matter?

The short answer is that this major decision will impact anyone needing an environmental review for federal approvals or funding. NEPA practitioners are still pondering the consequences of this decision, and how it will impact recipients of federal funding and project proponents needing environmental reviews has yet to be fully determined. While each of the agencies has its own NEPA regulations, the CEQ rules have been the cornerstone of all NEPA review for decades. Clients with recently completed approvals that are likely to be challenged, those wanting to challenge recent agency decisions or those that are currently going through environmental reviews should consult and work closely with attorneys focused on NEPA about the potential fallout from this decision.

Contextual Background

When President Richard Nixon signed NEPA into law in 1970, no one anticipated it would play such an outpaced role in the federal decision-making process or become the most litigated environmental statute in the nation. ¹ The statute itself, as originally enacted, consisted of a few short pages, the thrust of which imposed an obligation on all federal agencies to prepare a "detailed statement" for "major Federal actions significantly affecting the quality of the human environment," 42 U.S.C. § 4332(2)(C), and created CEQ in the Executive Office of the President of the United States. 42 U.S.C. § 4342.

Notably absent from CEQ's statutory duties and functions was any mention of authority to issue regulations. 42 U.S.C. § 4344. Instead, the U.S. Congress explicitly envisioned an advisory role for CEQ while directing each agency to develop its own regulations to comply with NEPA. 42 U.S.C. §§ 4333, 4344. This statutory framework closely paralleled the Council of Economic Advisers (CEA) model – another executive office entity created to advise the president without regulatory authority.

The transformation of CEQ from advisory body to regulatory agency occurred through two pivotal executive orders. First, President Nixon's Executive Order 11514 authorized CEQ to issue "guidelines" to assist agencies in preparing EISs. These guidelines focused on making the EIS process more useful to decision-makers and the public by reducing paperwork and emphasizing real environmental issues. ⁴ Importantly, these guidelines were explicitly nonbinding.

Though the Supreme Court has noted that CEQ's 1978 regulations are entitled to "substantial deference," it has never squarely addressed CEQ's authority to issue binding regulations. ⁷ Over the decades, various courts have questioned this authority but always stopped short of directly addressing it. As the D.C. Circuit observed in its recent ruling, "it is quite remarkable that this issue has remained largely undetected and undecided for so many years in so many cases."

Recent History of NEPA Regulations

The 2020 regulations marked the first comprehensive revision of CEQ's NEPA implementation framework since 1978. These regulations sought to establish a ceiling for NEPA requirements, requiring agencies to adjust their regulations accordingly. The revisions aimed to streamline the process by incorporating decades of judicial interpretation into regulatory text.

The Biden Administration's response came in two phases. Phase 1 regulations made targeted amendments to the 2020 rules rather than wholesale revisions. Key changes included converting CEQ's regulations from a ceiling to a floor for agency NEPA requirements and reverting to the 1978 definition of environmental "effects" and "impacts."

Before CEQ could release its anticipated Phase 2 regulations, Congress intervened with the first substantial amendments to NEPA since its enactment. The federal Fiscal Responsibility Act (FRA) significantly codified several key provisions from the 2020 regulations into statute, including the basic framework of EIS, EA and CatEx reviews – marking the first time Congress had explicitly recognized these longstanding administrative creations in the statute itself. ¹² In addition, Congress codified timelines for completion of EISs (two years) and EAs (one year) and incorporated an entirely new cause of action under NEPA to allow for project proponents to enforce these timelines. It also set page limits – 150 pages for EISs, 300 pages for EISs with extraordinary complexity and 75 pages for EAs.

Eventually, the final Phase 2 proposal, issued earlier this year, highlighted CEQ's continued expansion of authority, incorporating substantive requirements for environmental justice and climate change into what had historically been recognized as a procedural statute. Several comments on this effort specifically challenged CEQ's regulatory authority. As captured in comments submitted by the Center for Environmental Accountability: "At the center of this procedural hypertrophy lay the Council on Environmental Quality. … NEPA did not delegate regulatory authority to CEQ – but CEQ, citing Executive Orders, purported to exercise it anyway."

CEQ's response to these authority challenges relied heavily on judicial precedent, citing eight circuit court decisions describing its regulations as "binding" or "mandatory." However, as the D.C. Circuit would later observe, none of these decisions had squarely addressed the fundamental question of CEQ's authority to issue binding regulations in the first place. Ultimately, CEQ concluded in its response to these comments that it disagreed with the assertions that it lacked regulatory authority.

The Current Case

The court emphasized that its ruling does not undermine NEPA's environmental protections. Individual agencies retain their statutory authority to implement NEPA through their own regulations, and courts will continue to enforce NEPA's requirements. What changes is CEQ's role – returning to its original congressional design as an advisory body rather than a regulatory agency.

Impacts

The D.C. Circuit's ruling adds significant uncertainty to environmental reviews and federal approvals while raising fundamental questions about the future of NEPA implementation. The impacts of this decision will reverberate through several key areas.

Marin Audubon's Future in the Courts

Immediate Effects on Environmental Reviews

The need for federal agencies and project proponents to grapple with these issues in ongoing environmental reviews is not diminished by the Marin Audubon decision, and environmental reviews for permitting decisions could be delayed as agencies develop solutions in real time while struggling to keep the new statutory deadlines for completion. Further, agencies that have relied on CEQ's regulations and subsequent revisions to complete environmental reviews may need to revisit their decisions and review their own NEPA regulations. It is unclear if such agency-specific regulations can even stand on their own, as many are limited in scope.

Agency NEPA Regulations

The decision comes at a time when administrations will be changing in the new year, along with changes to policy focus. Though many anticipated another round of potential changes to CEQ's regulations with the subsequent administration, how this decision impacts the options available to the new administration remains uncertain and provides new options. A new administration may still try to coordinate NEPA regulations through the CEQ, or it could simply bypass relying on CEQ and focus efforts at the departmental level for each federal agency.

The relationships between individual agency NEPA regulations and CEQ's now-invalidated regulations also presents complex questions. As noted in the Marin Audubon decision, a "wrinkle remains" – many agencies incorporated or adopted CEQ's regulations by reference but not necessarily the subsequent revisions. Thus, a question remains on whether an agency adopting CEQ's regulations would be a permissible exercise of its own rulemaking authority, since it has been held in other contexts that an agency cannot outsource its rulemaking authority to another entity that lacks that authority. ²⁴ And, even if an agency has adopted the CEQ regulations in the past, would that extend to any revision of the CEQ regulations?

In the future, federal agencies may diverge significantly in their NEPA implementation, as each department could theoretically select from CEQ's various regulatory approaches or choose to chart its own course. Regardless, new regulations should be anticipated, and interested parties will want to track and comment upon future NEPA rulemakings coming out of the agencies.

CEQ's Future Role

The ruling fundamentally alters CEQ's role in NEPA implementation. As an advisory body, CEQ may continue to advise the president on environmental policy, which could include providing guidance and recommendations on NEPA implementation, as well as coordination among agencies. In fact, the FRA amendments now provide a role for CEQ in designating a lead agency for NEPA reviews. ²⁵ However, CEQ's ability to issue binding regulations – either setting a floor or ceiling for agencies or to require that agencies follow specific procedures – and its authority to impose substantive requirements for analytical approaches of impacts or alternatives must now be questioned. It also remains to be seen whether Congress will tackle permitting reform with further amendments to NEPA and if any statutory changes would address CEQ's rulemaking authority.

This shift raises uncertainty about CEQ's ability to ensure consistent NEPA implementation across agencies and its role in addressing emerging environmental challenges, particularly when it comes to the new regulatory provisions surrounding analysis of impacts concerning climate change and environmental justice.

Practical Considerations for Project Proponents

Conclusion

The D.C. Circuit's ruling fundamentally alters the landscape of federal environmental reviews and creates significant uncertainty for project proponents. Companies and organizations navigating federal approvals or funding will need experienced counsel to help them adapt to this rapidly evolving situation.
