Pulling together the government records on Valar and Carbon County (details in carbon_site.json and mining.json). Earliest public hints came in Emery County, not Carbon (and at the April 2026 hearing Valar also promised 'to be open with all plans', gov-038): the state lab director told Emery's June 2025 hearing that Valar was 'looking at manufacturing in Emery or Carbon County' (gov-020), and at Emery's April 2026 land-sale hearing a commissioner called the lab-side purchase 'an intermediate step' while Valar looks for 'a larger piece of property with water' (gov-022). State steps: Trust Lands mapped the Wellington parcel on 9 April 2026 (mine-048); the state's RDCC notice of 20 April 2026 described an unnamed industrial and power project (csite-032); the Trust Lands board first named Valar on a public agenda on 10 August 2026 (csite-018) and approved the lease with a purchase option on 17 September 2026 (mine-011), its chair having spoken of working so the proposal 'is approved' (ppl-019). Carbon County: its commissioners signed a support letter on 29 June 2026 that no county agenda shows (mine-013, csite-026). Federal: no DOE, NRC or Federal Register record names a Carbon site (csite-020, gov-029); BLM lists separate pending Valar land applications in Emery and elsewhere (mine-006). Not found as of 2026-09-29: any Carbon County zoning, permit, development or incentive action for Valar (csite-012, csite-029); any GOED incentive for a Carbon site (csite-024 is Emery only); any Utah Energy Research Board or legislative item naming the Wellington site (csite-031, gov-019).
