Mariner East 1 Pipeline Operational Again

Energy Transfer LP announced that effective Monday, April 23 Mariner East 1 pipeline has resumed operations. The 350-mile, 8-inch NGL pipeline transports NGLs across Southern Pennsylvania to Energy Transfer’s Marcus Hook Industrial Complex in Delaware County, PA.

Energy Transfer said it worked closely with the Pennsylvania Public Utility Commission Bureau of Investigation and Enforcement (BI&E) throughout an extensive three-month investigation, through which Energy Transfer confirmed the integrity of the pipeline in the area of West Whiteland Township, Chester County, PA. The investigation also confirmed that at no time was Mariner East 1 ever destabilized in this area, the company said.

Mariner East 1 is part of Energy Transfer’s Mariner East system of pipelines designed to provide much-needed NGL takeaway capacity for the Marcellus and Utica Shale production areas in Eastern Ohio, West Virginia and Western Pennsylvania.
