What was said

U.S. Department of Energy (categorical exclusion for Ward 250) (2026-04-22): "No active faults, landslides, or geologic hazards exist at or adjacent to site"; names only the Wasatch Fault Zone, about 150 km away; and "No major emission sources exist within 10 miles."

Valar Atomics (safety agreement, page 13) (2025-10): "Site-specific geotechnical data establishes design basis earthquake parameters"; aircraft impact negligible, with "no nearby airports".

What the record shows

Utah Geological Survey's Quaternary fault layer, re-queried on 29 September 2026 from a point beside the lab: six strands of the Joes Valley fault zone lie 14.7 to 19.0 km away, four of them mapped as having moved within the last 15,000 years.
Utah Quaternary Faults (distance query, 20 km around 39.244 N, 111.094 W, re-run 2026-09-29) (Utah Geological Survey)
The state's power-plant layer places the Hunter coal plant about 9.5 km (6 miles) from the lab (safe-022).

The same safety agreement, pages 40-41, says its earthquake values are 'preliminary, based on regional data and generic site conditions', with final values to follow site-specific studies, not yet done at that point.
Ward250 Nuclear Safety Design Agreement, No. 100403, Rev 02 (status: Draft), pages 40-41 (Valar Atomics, 2025-10)
The state's airport layer shows Huntington Municipal Airport about 20 km away (safe-021); whether that counts as 'nearby' is a judgment.

Read together, the safety paper's page-13 line ('Site-specific geotechnical data establishes design basis earthquake parameters') describes its method, and pages 40-41 say the values are preliminary and final parameters 'will be established following site-specific geotechnical investigations'. That is a plan, not a contradiction.

DOE's statement that no active faults, landslides or geologic hazards exist 'at or adjacent to site' holds on the state fault map: the nearest mapped strands are about 15 km away, not adjacent. The issue is what the review leaves out (the Joes Valley zone), not a false statement about faults.
NEPA Determination DOE-ID-26-005: Valar Ward250 Research Reactor (categorical exclusion B5.26) (U.S. Department of Energy, Office of Nuclear Energy, 2026-04-22)

The gap: DOE's statement that no major emission source lies within 10 miles is contradicted by the state's power-plant data, which place the Hunter coal plant about 6 miles away; the sentence sits in the air-quality section and does not change the radiological analysis. On faults, DOE's statement that none lies at or next to the site holds; naming only the Wasatch Fault, about 150 km away, leaves out the Joes Valley fault zone about 15 km away with young strands, an omission rather than a false statement. Valar's paper calls its earthquake values preliminary pending site studies; its page-13 wording describes the method and is not a contradiction.

In plain termsUnder its categorical exclusion, which does not require a full environmental study, DOE wrote a short review of the site. It says there is no major pollution source within 10 miles; the state's data put the Hunter coal plant about 6 miles away. That sentence concerns the area's background air, not the reactor's safety math. On earthquakes, the review correctly says no fault runs under or right beside the site, but the only fault it names is the Wasatch, about 95 miles away; it leaves out the Joes Valley fault zone about 9 miles away, parts of which moved in the last 15,000 years. None of this shows the reactor is unsafe in an earthquake. It shows a public review with one statement the state's data contradict and one notable omission.

Why it matters: A categorical exclusion rests on DOE's finding that the site has no extraordinary circumstances; missing a nearby young fault is the kind of fact that review is meant to weigh.

What would settle it: The site-specific seismic study and final earthquake parameters in the approved DSA (FOIA to DOE Idaho Operations Office); the CX file DOE-ID-26-005 including Valar's environmental checklist (FOIA).

facts safe-021, safe-022 · checked 2026-09-29: Defence pass 2026-09-29: Defended: re-read CX pp. 2-3 (the emission sentence is in the air-quality section; 'at or adjacent to site' holds) and NSDA pp. 13, 40-41 (method statement vs preliminary values: consistent). The earlier 'site data vs generic values' point and the airport point ('nearby' is a judgment) are withdrawn as conflicts. The emission-source sentence still conflicts with the state's power-plant layer (safe-022; the UGRC host answered 403 to robots.txt today, so it was not re-queried here). Summary line rewritten to quote the CX sentence exactly and state the distance from safe-022. | Earlier verify pass: Re-read on 2026-09-29: CX pp. 2-3 (quotes exact), NSDA pp. 13, 40-41. The UGS fault query was re-run in this pass (14.7-19.0 km; ages '<15,000' for four strands). The power-plant and airport distances rest on the safety pass (safe-021, safe-022); the UGRC services1 host's robots.txt answered 403, so it was not re-queried here. Synthesis check 2026-09-29: this entry gives the nearest Joes Valley strand as 14.7 km and safe-021 as 14.8 km, from the same day's query against a reference point good to about 2 km; the difference is rounding, and 'about 15 km' is used in plain text. | Correction 2026-09-29 (wording review): wording restated; verification wording updated ('summary line'). Correction 2026-10-01 (precision review): wording made more exact against the cited records.
