Williams Transco Northeast Supply Enhancement Project
This project has requested an extension of the FERC Certificate and all other permits are on hold.
May 31, 2016 — Williams is developing a pipeline project entitled the Northeast Supply Enhancement Project to expand its existing Transco transmission system to meet the increasing demand for natural gas in the northeastern United States for the 2019/2020 winter heating season. The company is in the preliminary stages of developing the proposal which is being designed to add 400,000 dekatherms per day of additional natural gas transportation capacity and is targeted to be in service for the winter heating season of 2019.
The preliminary project design in Chester County is limited to:
- Compressor Station 200, East Whiteland, Chester County, Pennsylvania - Add 21,000 HP by installing one electric motor-driven compressor unit
Additionally, the project will also include the following facilities located outside of Chester County:
- Approximately 10 mile, 42-inch loop (pipeline laid parallel to existing lines) in Lancaster County, Pennsylvania
- Greenfield Compressor Station 206, Somerset County, New Jersey - A new 32,000 HP compressor station near Transco's mainline consisting of two natural gas compressor units and associated facilities.
- Approximately 3.4 mile, 26-inch loop of Transco's existing Lower NY Bay Lateral from Transco 's Station 207 downstream to the Morgan metering and regulating station, Middlesex County, New Jersey (onshore)
- Approximately 22 mile, 26-inch pipeline near Transco's existing Lower NY Bay Lateral from the Morgan metering and regulating station in Middlesex County, New Jersey to the Rockaway Transfer Point, New York State waters (offshore)

- Project Website — Project specific information on the Williams website.
Before Williams can expand or modify its facilities, the company must first apply for and obtain a Certificate of Public Convenience and Necessity from FERC. The details of the pipeline project proposal have not been finalized, and a formal application has not yet been filed with FERC. Williams has, however, initiated an environmental pre-filing review of the project with FERC. The environmental pre-filing review is one of the first steps in the information gathering process and will help the company minimize impacts to the environment and communities.
All documents and correspondence submitted to or issued by the FERC regarding the Project can be accessed on FERC's website under docket number PF 16-5 You may also sign up for the FERC's e-subscription service which will allow you to be notified via email of all future submittals and issuances affecting this project.

Project Activity
Williams Gas decides to discontinue the Northeast Supply Enhancement project
After denials of permits for this project in both New York and New Jersey in May, Williams Gas has decided to pause the project indefinitely. View their official statement.
New York State denies the PA-NY Williams Northeast Supply Pipeline
On May 15, 2020 New York State's Department of Environmental Conservation said that the project would not meet the state's rigorous water quality standards, and New Jersey denied various permits related to water quality, wetlands, and flood hazard permits.

Draft Environmental Documents Submitted to FERC
November 23, 2016 — Williams Transco submitted to FERC a draft of environmental documents, known as resource reports, to allow the agency the opportunity to preview the initial data and design for the project. These reports include preliminary analyses of route alternatives, potential impact to water, vegetative and wildlife resources, cultural resources, soils, geology, land use, socioeconomics, noise air quality and safety. This draft analysis of potential impacts is ongoing, and as a result, contains placeholders for information that will be included in the formal application. The Northeast Supply Enhancement project only proposes changes to Compressor Station 200, located in East Whiteland Township. View the filing with FERC.
