The project was prposed to repurpose 50 mi of an 84-mi pipeline epurposed crude oil pipelines.[7] Adelphia Gateway LLC announced in November of 2017 that it's buying the underused pipeline for $189 million from Talen Energy Corp. and filed its 1,285-page application with the Federal Energy Regulatory Commission (FERC). Adelphia Gateway LLC, a subsidiary of New Jersey Resources, announced the filing.[8]

At the time of purchase, the underground pipeline delivered either oil or natural gas to two Talen power plants in Northampton County, but was to be converted to exclusively transport gas. Adelphia Gateway planned to convert the southern 50-mile portion of the pipeline, which formerly carried oil and has been idle since 2014, to transport gas southward to customers in Montgomery, Chester, and Delaware Counties. The Adelphia conversion project would require construction of two new 5,625-horsepower compressor stations, near Quakertown and in Marcus Hook. Adelphia also planned to build a new valve station at one of two proposed locations in Concord Township, Delaware County: Off Baltimore Pike, west of Stoney Bank Road, or next to Springlawn Road, near Purple Martin Drive. The plans include several meter and regulator facilities, typically where the pipeline connects with customers or meets other pipelines, and eight new "blowdown" assemblies located at existing valve stations. A blowdown is the release of gas from a pipeline to the atmosphere to relieve pressure so the pipe can undergo maintenance. Adelphia also proposes to build two new 16-inch-diameter lateral pipes to connect the planned Marcus Hook compressor station to the gas distribution systems of Peco Energy Co. and Delmarva Power.[8]

The pipeline is the latest piece in a massive regional buildout of energy infrastructure, triggered by the boom in fracked gas from the region's shale fields. The pipelines have aroused fierce resistance from neighbors and environmentalists, who oppose the expansion of fossil-fuel consumption.[8]

In June of 2018, the Delaware County Council was working towards hiring a consultant to perform a hazard analysis risk assessment of the pipeline. After putting out a request, it received one expert who met the specifications, Quest Consultants. However, several issues arose with that firm, particularly that it had performed work for a group opposed to the pipeline and that it did not provide its cost structure or analysis.[9]

In January of 2019, FERC released their environmental assessment of the project in which they stated there was no significant impact on the environment.[10]

FERC issued a Certificate of Public Convenience and Necessity for the Adelphia Gateway project in December of 2019.[11][12] As of February 2020, the project received the required air quality permits from the Pennsylvania Department of Environmental Protection, but still needs its state water quality assessment.[13] In October 2020, the pipeline received a notice to proceed from FERC and construction began in December 2020.[5]
