The Mariner East pipelines and related plant could have a potential $9 billion financial impact in the state over six years, according to a report by the firm EconsultSolutions.
Sunoco/Energy Transfer Partners, which is building the $2.5 billion pipeline, paid for the report. It analyzes the economic benefits of the Mariner East 1, 2, and 2X pipelines that will carry natural gas liquids from the western part of Pennsylvania and eastern Ohio about 350 miles across the state to a processing and export facility in Marcus Hook, Delaware County.
