FERC staff prepared a final supplemental EIS for the Commonwealth LNG Project in Cameron Parish, Louisiana, in response to the U.S. Court of Appeals for the D.C. Circuit's July 16, 2024 opinion finding that FERC failed to properly assess the cumulative effects of the project's nitrogen dioxide emissions. The court remanded FERC's 2022 authorization order. The supplemental EIS addresses only that remanded issue. The document is a Notice of Availability announcing the final supplemental EIS is available electronically; substantive impact analysis is in the underlying supplemental EIS, not this notice.12
