The Adelphia Gateway Project, traversing portions of Delaware, Chester, Montgomery, Bucks and Northampton counties will convert the remaining 50 miles of an existing 84-mile pipeline in southeastern Pennsylvania from oil to natural gas delivery. The northern 34 miles of the pipeline — extending from western Bucks County to Martins Creek Terminal in Northampton County — were converted to deliver natural gas in 1996. This project will repurpose the southern 50-mile portion of the pipeline to flow natural gas utilizing existing infrastructure and will require minimal new construction. Once converted, the pipeline will transport approximately 91 million dekatherms per year of natural gas to the greater Philadelphia market.

When in service, the pipeline conversion from oil to natural gas will give customers in the greater Philadelphia area a new, “competitively-priced” source of natural gas. Adelphia Gateway intends to have delivery interconnects with local distribution companies (LDCs) and other industrial end users, such as natural gas-powered electric generation facilities, in various locations along the pipeline route.
