The pipeline will carry, at various times, crude oil, condensate and natural gasoline. From Canton, Marathon plans to move condensate and NGLs to Midwest refining centers and into Canada. Other exciting news: Marathon’s engineering teams continue to “evaluate synergistic projects” for the Marcellus/Utica, including “a butane-to-alkylate facility, a regional NGL export solution in the Northeast, and a long-haul pipeline to the Gulf Coast, such as a reversal of the Centennial Pipeline.” Very cool.
