1. Case Information:

Case Name: Seven County Infrastructure Coalition et al. v. Eagle County, Colorado, et al.
Docket Number: 23–975
Dates: Argued December 10, 2024; Decided May 29, 2025
Lower Court: United States Court of Appeals for the District of Columbia Circuit

2. Facts of the Case:

In 2020, the Seven County Infrastructure Coalition, a group of seven Utah counties, applied to the U.S. Surface Transportation Board for approval to construct and operate an 88-mile railroad line in northeastern Utah's Uinta Basin. This railway aimed to connect the oil-rich region to the national freight rail network, facilitating the transportation of crude oil to Gulf Coast refineries.
The Board conducted an environmental review under the National Environmental Policy Act (NEPA), producing a draft environmental impact statement (EIS) and inviting public comment through six meetings and over 1,900 comments. The final EIS, spanning over 3,600 pages, analyzed numerous impacts of the railway's construction and operation but did not fully assess the environmental effects of upstream oil drilling in the Uinta Basin or downstream oil refining along the Gulf Coast.
In December 2021, the Board approved the project, concluding that its transportation and economic benefits outweighed the environmental impacts. Eagle County, Colorado, and several environmental organizations challenged the approval in the D.C. Circuit, which vacated the EIS and the Board's approval order, citing NEPA violations for failing to adequately analyze upstream and downstream effects.

3. Legal Issues Presented:

Question: Does NEPA require the Surface Transportation Board to consider the environmental effects of upstream oil drilling and downstream oil refining—projects separate in time and place from the proposed 88-mile Uinta Basin Railway—in its EIS?
Legal Basis: The case involves the interpretation of NEPA, a procedural statute requiring federal agencies to prepare an EIS for major federal actions significantly affecting the environment (42 U.S.C. §4332(2)(C)).
Arguments:
Petitioners (Coalition and Board): Argued that NEPA focuses on the proposed action (the railway itself) and does not mandate analysis of separate projects outside the Board's regulatory authority, such as oil drilling or refining.
Respondents (Eagle County and Environmental Groups): Contended that NEPA requires a broader analysis of reasonably foreseeable environmental impacts, including those from increased oil production and refining enabled by the railway.

4. The Court's Decision (Main Opinion):

Author & Type: Justice Kavanaugh, Majority Opinion (joined by Chief Justice Roberts, and Justices Thomas, Alito, and Barrett)
Holding: The D.C. Circuit erred by not affording the Board substantial judicial deference under NEPA and by requiring analysis of environmental effects from upstream and downstream projects separate from the Uinta Basin Railway. NEPA does not mandate such an analysis.
Legal Reasoning:
NEPA is a procedural statute that does not impose substantive environmental obligations but requires agencies to prepare an EIS for the proposed action, focusing on its direct and indirect effects, not separate projects.
Courts must defer to agencies' discretion in determining the scope and detail of an EIS, particularly regarding whether to analyze effects from projects outside their regulatory authority or separate in time and place, as supported by precedents like Department of Transportation v. Public Citizen (541 U.S. 752) and Metropolitan Edison Co. v. People Against Nuclear Energy (460 U.S. 766).
The Board lacks authority over oil drilling or refining, which are regulated by other entities, and thus is not responsible for their environmental effects under NEPA. The causal chain between the railway and these separate activities is too attenuated to require analysis.
Judicial review under NEPA must be limited and deferential, ensuring the agency reasonably explained its decision rather than micromanaging the EIS content.
Disposition: Reversed the judgment of the D.C. Circuit and remanded for further proceedings consistent with the opinion.

5. Concurring Opinion(s):

Author: Justice Sotomayor (joined by Justices Kagan and Jackson)
Reasons for Concurring: Agreed with the result but on different grounds, emphasizing precedent over policy considerations. Concurred that NEPA does not require the Board to analyze environmental impacts of oil drilling and refining because the Board's organic statute (49 U.S.C. §10901) and common carrier obligations (49 U.S.C. §11101) preclude it from rejecting or mitigating railway use based on transported commodities' end uses. Cited Public Citizen to affirm that agencies are not responsible for effects they cannot lawfully prevent, thus supporting the Board's decision to limit its EIS scope.

6. Dissenting Opinion(s):

Note: No dissenting opinions were filed in this case. Justice Gorsuch took no part in the consideration or decision of the case.

7. Potential Significance:

This ruling clarifies the scope of NEPA's requirements, establishing that agencies are not obligated to analyze environmental effects of projects separate in time, place, or regulatory authority from the proposed action. It reinforces judicial deference to agency discretion in defining EIS boundaries, potentially streamlining environmental reviews for infrastructure projects by limiting the scope of required analyses.
The decision may impact how courts review NEPA compliance, discouraging expansive interpretations that delay projects by mandating analysis of attenuated effects, and could influence future agency approaches to EIS preparation by focusing on direct project impacts rather than broader, speculative consequences.
