The proposed projects are being developed in response to natural gas market demands in the New York and the New England areas, and interest from natural gas shippers that require transportation capacity from Susquehanna County, Pennsylvania, to the existing Tennessee Gas Pipeline (TGP) and Iroquois systems in Schoharie County, New York.
The proposed projects would deliver up to 650,000 dekatherms per day of natural gas supply from Susquehanna County, Pennsylvania to the interconnect with the TGP and Iroquois systems at the existing Wright Compressor Station (to markets in New York and New England).
Associated facilities for the proposed Constitution Pipeline include:
- The addition of 22,000 horsepower of new compression at Iroquois’ existing Wright Compressor Station;
- Two meter stations;
- Ten communication towers;
- One pig launcher and one pig receiver; and
- Eleven mainline valves.
The Wright Interconnect Project involves the construction and operation of new compressor facilities adjacent to Iroquois Gas Transmission’s existing Wright Compressor Station and modifications to the existing Wright Compressor Station, and would be constructed completely within the property boundaries of its existing Wright Compressor Station.
Project proponent Constitution Pipeline Company is proposing to begin construction in February 2015, with an expected in-service date of late 2015 to early 2016.
FERC staff concluded that while the construction and operation of the projects would result in some adverse environmental impacts, these impacts would be “reduced to less-than-significant levels”.
FERC said that its determination is based on the review information provided by project proponents Constitution Pipeline Company and Iroquois Gas Transmission, and conducting field investigations, alternative analyses, contact with federal, state and local agencies, Native American tribes and other stakeholders.
FERC staff have published a list of project requirements and recommendations to ensure environmental impacts are minimised, which include erosion control plans, revegetation, HDD contingency plans, and specialised crossing methods for waterbodies and wetlands.
The FERC Commissioners will take the staff’s recommendations into consideration when making a final decision on the projects. A final decision is expected from late November.
