40 F.4th 1133
10th Cir.2022Background
- Rocky Flats NWR (≈6,200 acres) surrounds a former DOE nuclear facility cleaned under EPA/CDPHE oversight; EPA certified cleanup for the Refuge (excluding the Industrial Area) in 2007 and DOE transferred most lands to the Fish and Wildlife Service (Service).
- The Service adopted a 2004 CCP/EIS and 2005 ROD authorizing public use with ~16 miles of trails; cleanup standards and risk thresholds (50 pCi/g) were established during remediation.
- In 2018 the Service issued an Environmental Action Statement (EAS) modifying several trail alignments, including a ~1-mile extension into a newly acquired Section 16 parcel; the EAS excluded potential future changes in the eastern “Wind Blown Area.”
- The Service relied on Departmental categorical exclusions (516 DM §8.5) to avoid an EA/EIS and concluded no extraordinary circumstances applied; it reserved NEPA review for any future Wind Blown Area decisions.
- Rocky Mountain Peace and Justice Center and allied groups sued under the APA/NEPA and ESA, sought a preliminary injunction, and asked the district court to supplement the administrative record; the district court denied relief and dismissed the ESA claim for lack of standing.
- The Tenth Circuit affirmed: it held the Center has standing to pursue its NEPA claims (via a member affidavit), lacks standing for the ESA claim, and found the Service’s segmentation, use of categorical exclusions, and refusal to prepare a supplemental EIS were not arbitrary or capricious; the court also upheld the district court’s refusal to supplement or admit extra-record evidence.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| NEPA standing | Center: organizational standing via member (Lipsky) who uses area and faces increased radioactive-dust risk from modified trails | Service: (later) contested standing; initially did not | Held: Center has NEPA standing—Lipsky’s use + alleged increased risk suffice for injury, traceability, and relaxed redressability for procedural claims |
| ESA standing | Center: relies on member Stafford’s interest in Preble’s mouse to challenge project under ESA | Service: Stafford’s alleged injury stems from the original 2004 ROD/opening, not the 2018 trail modifications | Held: No ESA standing—Center failed to show Stafford’s injury is fairly traceable to the 2018 EAS |
| Segmentation (Wind Blown Area) | Center: Service impermissibly segmented analysis by excluding potential Wind Blown Area changes from the 2018 EAS | Service: 2018 trail changes have independent utility and are not connected/cumulative with possible future Wind Blown Area actions | Held: Proper segmentation—independent-utility test satisfied; not arbitrary or capricious to defer NEPA on speculative future changes |
| Categorical exclusions / extraordinary circumstances / supplemental EIS | Center: extraordinary circumstances (public-health risks from plutonium; project is highly controversial) and Section 16 acquisition/trail extension required supplemental EIS | Service: exclusions apply (minor trail changes); no extraordinary circumstances tied to the 2018 EAS; Section 16 acquisition and 1-mile extension were evaluated earlier and are not a new significant circumstance | Held: Service permissibly relied on categorical exclusions; Center failed to show extraordinary circumstances or need for supplemental EIS; district court did not err in refusing to supplement or admit extra-record material |
