Historically low natural gas prices and the public’s desire for cleaner energy have fueled the growing popularity of natural gas. Clean-burning natural gas currently produces one-third of all electric generation and heats about half of all U.S. homes – and those numbers continue to climb.

Williams, a leading energy infrastructure company, has partnered with Cabot Oil & Gas, Piedmont Natural Gas, and WGL  Holdings to develop a major transmission pipeline project to connect abundant Appalachian natural gas supplies in northern Pennsylvania with major northeastern markets.

The approximately 124-mile Constitution Pipeline has been designed with a capacity to transport 650,000 dekatherms of natural gas per day (enough natural gas to serve approximately 3 million homes). Buried underground, the 30-inch pipeline will extend from Susquehanna County, Pa., to the Iroquois Gas Transmission and Tennessee Gas Pipeline systems in Schoharie County, N.Y. The pipeline route stretches from Susquehanna County, Pa., into Broome County, N.Y., Chenango County, N.Y., Delaware County, N.Y., and terminates in Schoharie County, N.Y.

Natural Gas Production

The Constitution Pipeline has been designed to transport natural gas that has already been produced in Pennsylvania. The pipeline is not dependent upon nor does it require the development of new natural gas wells along the project’s proposed path. The pipeline is already fully contracted with long-term commitments from established natural gas producers currently operating in Pennsylvania.

Permitting Process

On Dec. 2, 2014, the Federal Energy Regulatory Commission issued an Order granting a Certificate of Public Convenience and Necessity for the Constitution Pipeline project (docket number CP13-499). To view the Order, click here. FERC issued this document to signify that approval has been granted to build and operate the pipeline. The certificate details the conditions of the approval, including the final route FERC has authorized, and construction and mitigation measures that must be followed.

Constitution Pipeline Company initiated a pre-filing environmental review of the proposed pipeline route in April 2012. The FERC pre-filing process solicits early input from citizens, governmental entities and other interested parties to identify and address issues with potential facility locations. The company hosted a series of public open houses during the summer of 2012 in the affected areas to formally introduce the proposal to the public and solicit feedback.

The FERC  issued its Final Environmental Impact Statement on the project on Oct. 24, 2014, concluding that environmental impacts would be reduced to “less than significant levels” with the implementation of proposed mitigation measures by the company and FERC.

Milestone Schedule

  • April 2012 – Pre-filing process began
  • June 2012 – Ground surveys began
  • July & Sept 2012 – Open houses and informational meetings
  • Fall 2012 – FERC scoping hearings
  • June 2013 – 7(c) application submitted to FERC
  • February 2014 – FERC issues draft EIS
  • October 2014 – FERC issues final EIS
  • December 2014 – FERC approval
  • Spring 2016 – Construction scheduled to begin
  • Fourth Quarter 2016 – Target in-service


Constitution Pipeline Company worked with the Center for Governmental Research to develop a formal economic analysis of the potential economic benefits generated by the project. That formal study, which was completed in January 2013 and updated in July 2013, indicates the economic impact during the construction phase would result in $130 million in new labor income in the region, approximately $26 million going to residents of the region.

During the construction phase, it is estimated that the workforce will be comprised of five teams of 260 workers totaling up to 1,300 new construction jobs. It’s estimated that 2,400 direct and indirect jobs will be created during the construction phase, with about 50 percent of the construction workforce coming from in-state labor. At this time, it is anticipated that approximately 25 percent of the construction workforce will be hired locally (i.e., within the 5-county project area).

The project is expected to generate $17 million in new sales and income tax revenue. Constitution Pipeline projects to spend about $683 million during the initial three year planning and building process, approximately $166 million of which would directly benefit the five county region. Once operational,  the pipeline’s economic impact is anticipated to result in $13 million in new annual sales, income and property tax revenue and more than $600,000 in new income in the region.

Projected Annual Property Tax Benefit:

  • Broome County – $2.1 million
  • Chenago County – $1.3 million
  • Delaware County – $4.9 million
  • Schoharie County – $4.4 million

Local Natural Gas Service

Constitution Pipeline would be considered an “open access pipeline,” meaning that local municipalities or public utilities could potentially tap the line in the future to provide residential, commercial and industrial natural gas service.

One such provider Constitution is working with is Leatherstocking Gas Company, LLC. In March 2014 Constitution Pipeline and Leatherstocking announced an agreement to install four delivery interconnects along Constitution’s proposed pipeline route for the purpose of facilitating potential local natural gas service. Leatherstocking’s plan is to develop local natural gas distribution systems within Broome, Chenango, Delaware, and Madison Counties in New York State and Susquehanna County in Pennsylvania in locations currently without natural gas service.

Our Commitment

Constitution Pipeline Company is committed to working with landowners, as well as local, state and federal agencies, to design and construct the project in a manner that minimizes environmental and landowner impacts. The company is committed to extensive public outreach in advance of submitting our application to the FERC. Our goals are to:

  • Generate a broad awareness of the project, its purposes and value to the region’s economy and to meeting the future energy needs of the state and region.
  • Ensure that community residents and a broad range of stakeholders have ample opportunity to understand the process and their rights, ask questions, voice concerns and present ideas about the project.
  • Create an atmosphere of openness, disclosure and public dialogue in which we can respond to questions, concerns and suggestions presented by the community and other stakeholders.
