Sunoco Logistics Partners L.P. announced Thursday that it will build an enormous, $2.5 billion pipeline project that will quadruple the volume of Marcellus Shale natural gas liquids moving through the Philadelphia area.
The Mariner East 2 project, the second phase of a plan to move materials like propane, butane, and ethane from Appalachian shale-gas fields, would dramatically expand industrial activity at the company’s Marcus Hook Industrial Complex.
Sunoco Logistics said it would build a pipeline at least 16 inches in diameter to follow the route of its first Mariner East project, an 83-year-old fuel pipeline crossing Pennsylvania that the company is repurposing to carry liquids to Marcus Hook.
Industry and political leaders have rallied behind the Mariner East projects as a way to closely tie Philadelphia to the Marcellus Shale region, which now accounts for nearly a quarter of the nation’s natural gas production.
