Project Details

  • Operator: Transcontinental Gas Pipe Line Company, LLC (Transco)
  • Parent Company: Williams Partners L.P.
  • Current capacity: 16.8 Bcf/d[3]
  • Length: 10,200 miles / 16,415 km
  • Status: Operating
  • Start Year: 1950

Background

The Transcontinental Gas Pipeline is operated by Transcontinental Gas Pipe Line Company, LLC (Transco), a subsidiary of Williams Partners L.P.[4]

Settlements

In a 2002 settlement with the EPA and U.S. Department of Justice, Williams Partners agreed to test the soil and groundwater near some of its compressor stations for contamination. This settlement also included a $1.4 million fine and a cleanup program for polychlorinated biphenyl (PCB).[5] “This settlement resolves Transco’s past illegal disposal practices and commits the company to a comprehensive testing and cleanup program that will protect public health and the environment,” said Sylvia Lowrance, EPA’s Acting Administrator for Enforcement and Compliance Assurance.[5]

Connection to Sabine Pass LNG

In 2017 the pipeline was extended to connect to the Sabine Pass LNG facility in Cameron Parish, Louisiana.[6] In February 2018 the Federal Pipeline and Hazardous Materials Safety Administration ordered a seven-day shutdown for a storage tank at the facility in which supercold natural gas leaked between the tank's inner and outer walls, on Jan. 22, 2017[7] An investigation of the leak uncovered 11 similar incidents that had occurred between 2008 and 2016.[7] "This incident is a reminder that the expansion of LNG projects poses a grave threat to our communities and our climate," said Nathan Matthews, a staff attorney for the Sierra Club, which released a copy of the report to the public after discovering it on Friday. "It's a relief that no one was hurt, but allowing the facility to continue to operate until it's clear how widespread these issues are would be extremely reckless."[7]

Financing

Recent financial support for Transcontinental's operations has involved debt financing via bond issues. In January 2016, a US$1 billion private bond placement was underwritten by Barclays, JP Morgan, RBC, Scotiabank and TD Bank.[8] This was followed in March 2018 by the refinancing of existing company debt through a US$1 billion bond issue involving JPMorgan Chase, Barclays, Crédit Agricole and Wells Fargo.[9]

Expansion projects

Virginia Interconnect Project

The Virginia Interconnect or VNG Interconnect expansion will add an interconnect between Virginia Natural Gas and the Transco Pipeline. VNG had planned to build the Interconnect in Northern Virginia primarily based off of plans from a previously cancelled project called the Header Improvement Project.[10] The project involves adding a new compressor station in Prince William County, Virginia and upgrades to the Mechanicsville, Virginia metering station.[11]

The project was cancelled in 2021, citing the shifting financial priorities of developers.[10]

Southeastern Trail Expansion Project

The project will add additional bidirectional capacity on the Transco pipeline. It received Federal Energy Regulatory Commission (FERC) in-service approval on December 23, 2020. Full completion and service of the pipeline was delayed until March 1, 2021 due to winter conditions. As of April 2021 the project was partially complete.[11]

Rivervale South to Market Expansion Project

In September 2017 Transco applied to FERC for permission for the Rivervale South to Market project, which would consist of updating 10.35 miles of existing Transco pipeline, adding a 0.61-mile pipeline loop, and upgrades and modifications to existing pipeline facilities, all in New Jersey.[13] The project would increase capacity by 190 mcfd.[13] The planned in-service date is November 2019.[13]

There have been no development updates since the project was first proposed in 2017, and it it presumed to be cancelled.[13]

Northeast Supply Enhancement Project

The Northeast Supply Enhancement (NESE) project, included the enhancement of existing Transco infrastructure (the Transcontinental Gas Pipeline) in Pennsylvania, New Jersey, and New York. The initial application for permits for the project were submitted in June 2017.[14]

In January 2019, Williams Companies applied for permits to build the Northeast Supply Enhancement (NESE) Pipeline as an extension of the Transco that would add ten miles of pipeline in Lancaster, Pennsylvania and 27 miles in New Jersey and New York.[15] The pipeline was proposed to transport gas from Pennsylvania through New Jersey, travel underwater in the Raritan Bay and Lower New York Bay, ending about three miles offshore the Rockaway Peninsula in the Queens Borough of New York City.[16]

In May 2019 the New York Department of Environmental Conservation rejected the pipeline, stating, "Construction of the NESE pipeline project is projected to result in water quality violations and fails to meet New York State’s rigorous water quality standards."[17][2]

Environmentalists warned that the proposed expansion would damage wetlands in New Jersey. The pipeline would require a trench to be dug in the wetlands, a natural infrastructure that provides wildlife habitats, filters storm water and act as a flood buffer, noted Hackensack Riverkeeper Bill Sheeran."[18] "The wetlands are the first line of defense against really bad things that can happen to really good people," Sheeran said. "This is just another corporation trying to chip away at the environmental quality of the Meadowlands."

Ahead of the May 17, 2020 deadline for the New York State Department of Environmental Conservation to rule on a key permit for the pipeline expansion project, more than 100 protesters participated in a virtual rally against the proposed expansion which would cut through northern New Jersey and then out approximately 23 miles into New York Harbor to connect with the city's existing gas system. New York City Comptroller Scott Stringer said: “We can’t pretend we are making progress on combating climate change if we continue to build out fracked gas infrastructure that will lock in emissions for years to come.” National Grid has been criticised by groups such as the Environmental Defense Fund and NY Renews, an environmental justice coalition of more than 200 groups across New York State, for failing to analyse the emissions impacts of various gas supply scenarios which the company has published since its original pipeline proposal was rejected by the New York Department of Environmental Conservation in May 2019.[19]

In July 2020, Forbes reported that the NESE expansion had been cancelled in light of the developer's failure to obtain the necessary water permit.[20]

In March 2021, Transco requested a two-year extension of the time to construct and place the pipeline into service.[21] According to EIA, as of May 2021, the status of the project os 'Announced' and expected to begin service in 2023[22]

The project had encountered heated opposition from activists due to the expected costs and ultimate impacts on climate change, human health.[23]

In May 2024, after multiple rejected permits, Williams abandoned the expansion project.[24]

In November 2017, Transco applied to FERC for permission to proceed with its Gateway Expansion Project, which includes building a new compressor unit at Transco’s existing Compressor Station 303 in Essex County, NJ, a new valve and electric transformer also in Essex County, and equipment upgrades at a metering station in Passaic County, NJ.[27]

The expansion project involves the replacement of valves, compressors, and associated equiptment to improve natural gas deliverability. It does not include laying any additional miles of pipeline. According to the U.S. Energy Information Administration (EIA) construction was completed in November of 2019, but the in-service date remains 2021.[22]

Appalachian Connector

The Appalachian Connector, also referred to as the Western Marcellus Pipeline[34][35], was a proposed extension to the Transco Pipeline that would have added gas supply from fields in the Marcellus basin in order to meet both demand domestically and for LNG exports abroad. The pipeline was proposed in 2017 but disappeared from Williams' investor documents and suggestions thereafter. As of December 2021, it had been over four years since development had occurred on the project, so it is considered cancelled.
