## Summary

Coverage and docket records on US Magnesium LLC's September 10, 2025 Chapter 11 filing in Delaware (Case No. 25-11696), its EPA Superfund status, and the January 2026 auction in which the Utah Division of Forestry, Fire, and State Lands was selected as the winning bidder for the company's assets.

## Useful Claims

- US Magnesium operated a magnesium plant in Rowley, Utah (Tooele County), on the western shore of the Great Salt Lake, beginning production in 1972.
- The company filed Chapter 11 on September 10, 2025 in the U.S. Bankruptcy Court for the District of Delaware; Wells Fargo provided DIP financing.
- US Magnesium's sole member, The Renco Group (Ira Rennert-affiliated), provided more than $400 million in funding over the prior decade and took no dividends, per the first-day declaration.
- The site has been on the EPA's National Priorities List (Superfund) since 2009; a 2021 consent decree resolved 20+ years of RCRA litigation and required a barrier wall and financial assurance. EPA notified the company of a consent-decree violation in July 2024.
- Following a January 21, 2026 auction, the Utah Division of Forestry, Fire, and State Lands (FFSL) was selected as successful bidder with a reported $30 million cash offer; a Renco affiliate (LiMag Holdings, formed the day of the bankruptcy filing) had earlier been a proposed bidder.
- Court filings reference development of lithium carbonate production from magnesium-production tailings.

## Reliability Notes

Mix of primary court documents (high reliability for filing facts) and newspaper coverage (reliable but evolving). The bankruptcy and sale are an active, developing situation as of mid-2026; ownership, the buyer of record, and whether magnesium production continues should all be re-verified before relying on this page for employment or supply-chain decisions. The environmental record is well-documented through EPA primary sources.
