As of late September 2026: the Trust Lands board voted unanimously on 17 September 2026 to approve an 'Other Business Arrangement' with Valar Atomics on Section 16, T14S R11E, about five miles north of Wellington: 480 acres now, the other 160 if a National Guard lease is moved, 50 years plus two 25-year extensions, with an option to buy (csite-004, mine-011). The stated purpose is an integrated nuclear energy, advanced manufacturing, critical mineral refining and data center campus: high-temperature gas-cooled reactors, TRISO fuel manufacturing, hydrogen and synthetic fuels, desalination and steel. Separately, a Notice of Location names Valar Atomics Inc as locator of the 'RW 453' lode mining claim in Section 28, two miles south, located 12 September 2026; it is not yet in BLM's public claim layer, which the 90-day recording window allows (mine-453, dir-005). No county permit application, state DEQ permit or DOE/NEPA document for the Carbon site was found (csite-012, csite-020). Whether any NRC filing exists was not checked, and water-right filings were not searched. The only official actions found are the board's vote and the commissioners' 29 June support letter, which was not found on any Carbon County Commission agenda posted for its 6 May to 16 September 2026 meetings (mine-013, csite-026). No departure from the notice rules read was found (csite-005, csite-016, csite-018), but the first public document found naming Valar for the site was posted on 10 August 2026, and the April state review notice did not say nuclear (csite-032). Open questions: waste-storage framing (csite-008), the NRC route vs the CEO's 2025 stance, a one-test NEPA review vs a larger build-out, officials' praise of Valar's openness beside county agendas that did not name the site (disc-031), and a lode claim with no mineral stated (disc-003).

In plain termsIn short: the state has agreed to rent Valar about three-quarters of a square mile north of Wellington (the whole square mile later if a National Guard lease is moved, with an option to buy) for a future nuclear and industrial campus. Nothing has been built there, and no application for the permits that would allow building appears in the records we could check. The deal followed the notice rules we could check, but those rules kept the company's name and plan out of the first public notices, and the first public record found naming Valar for the site came about five weeks before the vote. Separately, a Notice of Location shows Valar has staked a mining claim two miles south. The next steps (a county permit, water rights, state and federal nuclear approvals) are where the public can still weigh in.

verified 2026-10-02: Re-checked in late September 2026 against the September memo (pp. 18-27), the 17 Sept transcript (motion; 'Is unanimous') and each cited fact. Corrected: the earlier 'Valar holds no mining claims there' is superseded by the Notice of Location (mine-453); 'critical mineral refining' added from the memo summary; NRC filing status now stated as unchecked, not as absent.
