Constitution Pipeline Company has filed an application with the Federal Energy Regulatory Commission (FERC) for the approval to build a 122 mile pipeline in northeastern Pennsylvania, US.

The capital cost to build the project is expected to be about $683m.

The company plans to connect domestic natural gas production in northeastern Pennsylvania with northeastern markets by spring 2015.

The pipeline has been designed to supply about 650,000 dekatherms of natural gas per day to serve about 3 million homes.

The pipeline project will supply gas from Williams Partners’ gathering system in Susquehanna County in Pennsylvania to Iroquois Gas Transmission and Tennessee Gas Pipeline systems in Schoharie County in New York.

Constitution Pipeline members in a joint statement said, "The Constitution Pipeline would become a key piece of natural gas infrastructure in the region, supporting the overall reliability and diversification of energy infrastructure in the northeastern US and helping our nation realize the full benefit of these abundant, clean-burning natural gas supplies."
