On paper, it might appear that Sunoco Logistics Partners is having a difficult time figuring out the logistics of pipelines, even though that’s its core business. In September 2018, for instance, Sunoco began operating a new, 100-mile natural gas pipeline in Pennsylvania called the Revolution. One week into service, a segment of the Revolution was hit by a landslide and subsequently exploded, leveling a house and forcing an evacuation about 30 miles outside Pittsburgh.

As state regulators began investigating the Revolution explosion, Sunoco moved ahead with construction on a different group of pipelines in Pennsylvania known as the Mariner East project, despite concerns from locals that this project could be even more explosive.
