Energy & Energy Services
The Mariner East pipeline system provides the needed infrastructure to transport propane, ethane and butane, all known as natural gas liquids (NGLs), from the Marcellus and Utica Shale fields to markets in Pennsylvania and beyond.
The Mariner East system comprises the Mariner East 1, Mariner East 2 and Mariner East 2X pipelines. Together, these pipelines continue to create thousands of well-paying construction jobs and support hundreds of permanent, family-sustaining jobs.
The pipelines provide a safer means to deliver NGLs that are otherwise transported through neighborhoods on trucks and trains. They also support continued production in the shale fields in western Pennsylvania, Ohio and West Virginia, bringing further economic growth and opportunity across the state.
Energy Transfer is committed to safety at the highest level. The safety of our employees and the community is our highest priority, and we believe that no project is worth doing if it cannot be done safely.
