FERC SEIS Addresses Nitrogen Dioxide Concern

The SEIS is part of FERC’s further proceedings on the Project (dockets CP19-502-000 and CP19-502-001) and follows the Commission's earlier actions including the September 9, 2022 final EIS, the November 17, 2022 authorization order, and the June 9, 2023 rehearing order.
Final SEIS Is Only Available Electronically
The final supplemental EIS is available only in electronic format on FERC's website and eLibrary (docket CP19-502); FERC mailed a Notice of Availability to federal, state, and local officials, Tribes, environmental and public interest groups, potentially affected landowners, newspapers, and libraries. FERC provided contact points for assistance (FERC Online Support, OPP phone numbers and email) and an eSubscription service to receive notices and documents.
