Tennessee Gas Pipeline (TGPL) is a set of natural gas pipelines that run from the Texas and Louisiana coast through Arkansas, Mississippi, Alabama, Tennessee, Kentucky, Ohio, and Pennsylvania to deliver natural gas in West Virginia, New Jersey, New York, and New England. The long system is operated by the Tennessee Gas Pipeline Company, a subsidiary of Kinder Morgan. It is one of the largest pipeline systems in the United States. Its FERC code is 9. TGP's PHMSA pipeline operator i.d. is 19160. History The first pipeline was constructed by Tennessee Gas Transmission Company (TGT) beginning in 1943. In 1996, TGT-owner Tenneco was acquired by El Paso Corporation, which was in turn acquired by Kinder Morgan in 2012. Expansion projects In 2014, Kinder Morgan proposed Northeast Energy Direct Project (NED), a new branch of of greenfield pipeline to move natural gas from Pennsylvania to Wright, New York, and of greenfield pipeline to Dracut, Massachusetts. The Kinder Morgan proposal met with immediate resistance from local and state officials, conservation organizations, and more than 20 Massachusetts towns that the proposed pipeline would cross. Public and environmental safety was the primary concern, due to TGP's history of pipeline accidents. The pipeline route was heavily debated amid complaints about eminent domain and widespread refusal of Kinder Morgan's requests to survey the route. The proposed route would cross land that is heavily wooded with sensitive eco-systems, conservation lands, wildlife reserves, state parks, farmland, towns, and the Connecticut River. KM proposed that "approximately 91% of the NED Market Path Component would be co-located along existing utility corridors/adjacent to TGP mainline. The total project (both Supply and Market Path Components) would be 82% co-located." An alternative would be to follow the Massachusetts Turnpike highway system from western Massachusetts into Boston. Supporters claimed that the pipeline would have positive impacts. "The pipeline is not only a pipeline for natural gas, but it is a pipeline for new construction and jobs." KM claimed, "NED helps sustain electric grids, reduce emissions, lower energy costs and spur economic growth region-wide." The new pipeline would "bring up to of natural gas from the Marcellus shale fields to New England and Canadian markets." The planned pipeline was roughly long and would be in diameter. The design would include "large, powerful compressor stations." Detractors pointed out the safety issues involved with locating a high-volume, high-pressure gas transmission pipeline through towns and near neighborhoods that would
