ExxonMobil Low Carbon Solutions Onshore Storage, LLC (Board decision, February 2, 2026)

Plain-English summary

ExxonMobil Low Carbon Solutions Onshore Storage, LLC held three Underground Injection Control permits issued by EPA Region 6. EPA notified the EAB that it was withdrawing all three permits in their entirety under 40 C.F.R. § 124.19(j). Because the permit withdrawal removed the live dispute, the Board dismissed the petition for review as moot without reaching the merits. The order also denied any pending motions as moot.
