NEPA Standing Requires a Concrete, Imminent Environmental Risk Tied to an Agency’s Own NEPA-Triggering Decision—Not Treasury Tax-Credit Regulations That Merely Fail to Mandate NEPA Review

1. Introduction

Hoffman v. United States Department of Treasury (10th Cir. July 7, 2026) arose from a challenge by four Jackson County, Kansas landowners and the neighboring City of Rossville (collectively, the “Landowners”) to federal regulations implementing renewable-energy tax credits created by the Inflation Reduction Act of 2022 (“IRA”). The Landowners alleged that the U.S. Department of the Treasury and related officials (collectively, the “Federal Defendants”) violated the National Environmental Policy Act (“NEPA”) by issuing IRA tax-credit regulations that did not require NEPA review as a condition to claim or transfer those credits.

The factual catalyst for the lawsuit was the proposed “Jeffrey Solar” project in Jackson County, developed by Jeffrey Solar, LLC (an intervenor defendant). The Landowners argued that the IRA’s incentives and Treasury’s implementing rules were enabling industrial solar development to proceed “without any NEPA review,” increasing environmental risk near their properties and community.

The central issues on appeal were jurisdictional: whether the Landowners had Article III standing—particularly, whether they alleged an injury in fact cognizable under NEPA’s procedural framework—and, only alternatively, whether they stated a viable NEPA claim.

2. Summary of the Opinion

The Tenth Circuit affirmed dismissal under Rule 12(b)(1) for lack of jurisdiction, holding the Landowners lacked standing because they failed to plead an injury in fact under NEPA. The court reasoned that:

  • The Landowners did not identify a NEPA procedural requirement the Federal Defendants failed to follow (e.g., failure to prepare an EIS or EA for a specific discretionary federal action).
  • Treasury had no discretionary approval authority over construction of the private solar project, so there was no agency “proposal” or “action” for which Treasury would conduct NEPA review.
  • The asserted risk of environmental harm was conjectural and insufficiently imminent because it depended on future private conduct (construction of the project) rather than a concrete NEPA-triggering agency decision.

Because injury in fact was not established, the court did not need to resolve traceability and redressability, and it affirmed on standing grounds.

3. Analysis

3.1. Precedents Cited

Standing framework and “irreducible constitutional minimum”

The court anchored its standing analysis in the Supreme Court’s formulation that standing is an “essential and unchanging” requirement of Article III:

  • Lujan v. Defs. of Wildlife — provided the foundational three-part test (injury in fact, traceability, redressability) and the “case-or-controversy” lens through which NEPA procedural claims must still satisfy Article III.
  • Spokeo, Inc. v. Robins — reaffirmed the “irreducible constitutional minimum” of standing and the need for a concrete injury, preventing purely statutory or abstract grievances from entering federal court.
  • Friends of the Earth, Inc. v. Laidlaw Env't Servs. (TOC), Inc. — supplied the modern articulation of standing elements, quoted through Tenth Circuit precedent.

Tenth Circuit NEPA standing: “increased risk” plus “concrete interest”

The opinion’s core move was to apply the Tenth Circuit’s NEPA-specific injury-in-fact test:

  • Comm. to Save the Rio Hondo v. Lucero — the leading Tenth Circuit decision describing NEPA procedural injury as requiring (1) increased risk of actual, threatened, or imminent environmental harm from an agency’s decision made without NEPA procedures, and (2) harm to a litigant’s concrete interests (often shown via geographic nexus or site use). The panel treated Lucero as the operative test because the Landowners urged it, even while noting potential “analytical mismatch” given the “upstream” nature of Treasury’s regulations.
  • Sierra Club v. U.S. Dep't of Energy — restated the same two-part NEPA injury-in-fact requirement and was used to emphasize what was missing: a specific agency decision made “without following the NEPA’s procedures,” such as failing to prepare an EIS or EA where required.
  • Diné Citizens Against Ruining Our Env't v. Bernhardt — reinforced the injury-in-fact breakdown in NEPA contexts and, importantly, the procedural-injury doctrine’s approach to redressability (discussed below). The panel cited it as part of the governing architecture, but it ultimately did not reach redressability because injury in fact failed.

Traceability and relaxed redressability in procedural-injury cases (acknowledged but not dispositive)

  • WildEarth Guardians v. U.S. Bureau of Land Mgmt. — articulated that in NEPA procedural cases, causation can be shown by tracing increased risk to the agency’s failure to comply with NEPA and the resulting “uninformed decisionmaking.” The panel used this to highlight the Landowners’ conceptual problem: they sought NEPA “inquiries at some point” without identifying a federal decision that would be informed by that inquiry.
  • Rocky Mountain Peace & Just. Ctr. v. U.S. Fish & Wildlife Serv. — cited for the proposition that redressability is “relax[ed]” when plaintiffs allege procedural violations, but not eliminated.
  • Diné Citizens Against Ruining Our Env't v. Bernhardt and Comm. to Save the Rio Hondo v. Lucero — cited for the rule that plaintiffs need not prove the substantive outcome would change; they must show that requiring NEPA compliance would redress their procedural injury. The panel’s analysis implied that even this relaxed standard presupposes a cognizable NEPA procedural duty tied to agency decisionmaking.

Appellate review posture and Rule 12(b)(1) “facial” attacks

  • Pueblo of Jemez v. United States and Holt v. United States — provided the distinction between facial and factual Rule 12(b)(1) jurisdictional challenges. Because the district court treated the motions as facial attacks, the panel accepted the complaint’s allegations as true.
  • Muscogee (Creek) Nation v. Okla. Tax Comm'n — reaffirmed the standard of accepting complaint allegations in this procedural posture.

Party presentation principle and burden of establishing standing

  • Murthy v. Missouri and Carney v. Adams — cited to emphasize that plaintiffs bear the burden of establishing standing.
  • Greenlaw v. United States — invoked for the “party presentation” principle: courts generally decide cases on issues framed by the parties. Here, that principle supported applying the Lucero test because the Landowners embraced it, even if it was not a perfect fit for “upstream” regulations.

General standing articulation

  • Rocky Mountain Wild v. Dallas — supplied a current Tenth Circuit recitation of standing elements and the requirement that injury be “actual or imminent.”
  • Rocky Mountain Peace & Just. Ctr. v. U.S. Fish & Wildlife Serv. and Colo. Outfitters Ass'n v. Hickenlooper — cited for the plaintiff’s burden and related standing principles.

3.2. Legal Reasoning

(a) The court’s key doctrinal move: separating “failure to require NEPA” from “failure to follow NEPA”

The Landowners framed injury as Treasury’s failure to include NEPA procedures in IRA tax-credit regulations, resulting in construction of the Jeffrey Solar project “without any NEPA review.” The panel rejected this as a cognizable NEPA injury in fact because it did not identify a NEPA-required procedural step that Treasury itself failed to perform.

Under Sierra Club v. U.S. Dep't of Energy and Comm. to Save the Rio Hondo v. Lucero, the procedural injury recognized in NEPA cases arises when an agency makes a decision without NEPA procedures (commonly an EA/EIS process) and thereby creates an increased risk of environmental harm. Here, the Landowners did not allege Treasury failed to prepare an EIS or EA for a specific Treasury decision; rather, they alleged Treasury should have compelled private parties to conduct NEPA review as a condition of receiving tax benefits.

(b) No NEPA-triggering discretionary federal action by Treasury connected to the project’s construction

The panel emphasized NEPA’s target: it “requir[es] agencies to undertake analyses of the environmental impact of their proposals and actions.” The construction of the Jeffrey Solar project was a private undertaking, not subject to Treasury’s approval. Treasury’s role was limited to issuing tax regulations and administering tax credits, not authorizing siting, construction, or operation.

This matters because the “uninformed decisionmaking” theory in NEPA standing (as discussed in WildEarth Guardians v. U.S. Bureau of Land Mgmt.) presupposes an agency decision that NEPA is meant to inform. The panel found the Landowners did not identify such a decision here.

(c) Speculation and lack of imminence: future private construction is too remote to establish “increased risk”

Even assuming some NEPA duty could exist in an “upstream” regulatory context, the court concluded the Landowners still failed Lucero’s first prong: the complaint did not plausibly allege that Treasury’s conduct created an increased risk of “actual, threatened, or imminent” environmental harm. The alleged harm depended on future construction and operation decisions by Jeffrey Solar/NextEra and the future unfolding of a project that was not shown to be imminent in the Article III sense.

In short, the causal chain the Landowners proposed was: tax-credit regulations → incentives → private project moves forward → environmental harm. The panel treated that chain as too conjectural at the injury-in-fact stage because it was not tied to a concrete NEPA-triggering federal decision that itself created a cognizable increased risk.

(d) The court’s disciplined sequencing: stopping at injury in fact

Although the parties heavily briefed traceability and redressability, the panel followed standing doctrine’s logic: failure on injury in fact ends the analysis. The court therefore affirmed dismissal without needing to definitively resolve whether the requested relief (compelling Treasury to condition tax credits on NEPA review) could redress any injury.

3.3. Impact

Although labeled an “Order and Judgment” and “not binding precedent” (except for law of the case, res judicata, and collateral estoppel), the decision is likely to be cited persuasively in three recurring contexts:

  1. Challenges to federal incentive programs as “NEPA evasion.” Plaintiffs attempting to require NEPA compliance through federal funding, subsidies, or tax incentives may face heightened scrutiny on whether they can identify (i) a discretionary federal action by the defendant agency that NEPA actually governs and (ii) a concrete NEPA procedural step the agency failed to take.
  2. “Upstream regulation” theories of NEPA standing. The panel flagged (without resolving) a potential mismatch between Lucero and upstream regulatory actions, but still enforced Lucero’s core requirement: an agency’s own failure to follow NEPA procedures connected to an agency decision. That reasoning will likely discourage suits seeking to convert NEPA into a generalized requirement that agencies embed NEPA obligations into regulatory programs affecting private actors.
  3. Energy-transition litigation tied to private development. As renewable projects proliferate, litigants may target federal agencies that provide economic incentives rather than permits. This decision indicates that, at least where the agency lacks project-approval authority, standing may fail unless plaintiffs can tie environmental risk to a concrete federal authorization, funding decision, permit, or other NEPA-governed action.

4. Complex Concepts Simplified

  • NEPA (procedural statute): NEPA generally does not force agencies to choose the most environmentally protective option. It requires agencies to study and disclose environmental impacts before taking certain actions.
  • EIS / EA: An Environmental Impact Statement (EIS) is a detailed analysis for major actions significantly affecting the environment; an Environmental Assessment (EA) is a shorter analysis to determine whether an EIS is needed.
  • “Procedural injury” in NEPA cases: Plaintiffs can be injured when an agency skips NEPA steps, because that omission may increase the risk of environmental harm by producing “uninformed decisionmaking.” But plaintiffs must still show a concrete interest and a non-speculative, imminent risk tied to the agency’s decision.
  • Standing (Article III): To sue in federal court, a plaintiff must show (i) a real injury, (ii) caused by the defendant, (iii) that a court can likely remedy. Without these, the court lacks jurisdiction.
  • Facial vs. factual Rule 12(b)(1) motion: A facial challenge argues the complaint’s allegations are insufficient even if true; a factual challenge disputes jurisdictional facts with evidence. Here, the court treated the motion as facial.
  • “Upstream” regulation: Regulations that shape incentives or background conditions (like tax-credit rules) without directly approving a specific project. The court treated such upstream action as a poor fit for classic NEPA standing absent a concrete NEPA-triggering agency decision.

5. Conclusion

Hoffman reinforces a limiting principle for NEPA-based challenges aimed at federal incentive regimes: plaintiffs must tie their claimed procedural injury to an agency’s own NEPA-governed decision and to a concrete, imminent increased risk of environmental harm. Alleging that an agency’s regulations failed to require others to conduct NEPA review—where the agency itself neither authorizes nor approves the private project—does not, without more, establish injury in fact. The decision thus narrows the pathway for using NEPA to attack tax-credit and similar incentive frameworks when the asserted environmental harm flows primarily from future private development rather than a discrete federal action.
