US DOE approves Smackover Lithium project with no significant environmental impact, clearing path for investment decision.

The U.S. Department of Energy has completed its National Environmental Policy Act review of the Smackover Lithium South West Arkansas Project, issuing a Finding of No Significant Impact (FONSI). This approval means the project can proceed without additional federal environmental conditions, supporting a $225 million DOE grant awarded in 2025. The project partners, Standard Lithium and Equinor, plan to take a Final Investment Decision and start construction in 2026, aiming for commercial lithium production by 2029. This milestone advances U.S. efforts to develop a domestic critical minerals supply chain with responsible environmental practices.
