Case Notes - Seven County Infrastructure Coalition v. Eagle County

Case Name: Seven County Infrastructure Coalition et al. v. Eagle County, Colorado et al.
Court: Supreme Court of the United States
Decision Date: May 29, 2025
Docket Number: No. 23–975

NEPA (National Environmental Policy Act): Requires federal agencies to prepare an Environmental Impact Statement (EIS) before major actions affecting the environment.
Federal Approval: New railroad construction requires approval from the U.S. Surface Transportation Board (49 U.S.C. §10901).

Project: Proposed 88-mile railroad line from Uinta Basin, Utah to the national rail network, intended for transporting crude oil.
EIS Preparation: In 2020, Board prepared a 3,600-page EIS, analyzed environmental impacts, and invited public comments.
Public Engagement: Included six public meetings and collected over 1,900 comments.

D. C. Circuit Ruling: Found NEPA violations due to limitation of analysis regarding environmental effects from upstream oil drilling and downstream refining, leading to vacating the EIS and approval.

Judicial Deference: D. C. Circuit failed to give the proper judicial deference to the Surface Transportation Board under NEPA.
Focus of NEPA: The Court emphasized that NEPA focuses on the environmental effects of the proposed action, not separate projects.
Agency Authority: The Board cannot control effects from projects outside its regulatory authority.
Separateness of Projects: Recognized that upstream drilling and downstream refining were not part of the proposed action and should not be included in the EIS.

EIS Adequacy: The EIS was deemed adequate as it addressed significant environmental effects of the railroad line itself.
Causal Relationship: Environmental effects must have a reasonably close causal relationship to the proposed action; indirect effects justification does not mandate analysis of separate projects.
Final Ruling: Reversed D. C. Circuit's decisions and remanded for further proceedings consistent with its findings.
