FERC Seeks Updated Environmental Review for Constitution Pipeline

FERC requested updated environmental and engineering information for the proposed Constitution Pipeline as regulators continue reviewing efforts to revive the long-delayed Northeast gas project.

(P&GJ) — Federal regulators are seeking updated environmental and engineering information for the proposed Constitution Pipeline and associated Wright Interconnect Project as review efforts continue on the long-delayed Northeast natural gas expansion.

In a May 5 filing, the Federal Energy Regulatory Commission (FERC) requested Constitution Pipeline and Iroquois Gas Transmission provide updated environmental data, permitting information and revised project details within 20 days to support review of the companies’ requests for reissuance of pipeline certificates.

The information requests cover a broad range of issues, including updated greenhouse gas emissions estimates, revised construction schedules, endangered species surveys, wetland impacts, waterbody crossing methods and changes in land use along the proposed route. FERC also requested updated cost estimates, revised rate calculations and additional engineering information tied to compressor station modifications associated with the Wright Interconnect Project.

According to the filing, Constitution Pipeline is proposing to begin construction in the fourth quarter of 2026, though FERC noted discrepancies in project timelines submitted by the company and requested clarification regarding the expected in-service date.

The proposed Constitution Pipeline would transport Appalachian natural gas through portions of Pennsylvania and New York and connect with the Iroquois Gas Transmission system through the Wright Interconnect Project.

FERC’s latest filing signals the agency’s review process remains active as developers continue efforts to revive the previously approved project, which faced years of permitting disputes and legal challenges in New York.
