Sunoco scrambled to inspect an aging pipeline on Friday in the backyards of Chester County homes where drilling for two new pipelines has caused several sinkholes to open up.
Yellow backhoes dug holes in several places among homes along Lisa Drive and Lynetree Drive in West Whiteland Township after the Pennsylvania Public Utility Commission ordered Sunoco to temporarily halt operations of the Mariner East 1 pipeline. The PUC cited the risk of what it called “catastrophic results” if the pipeline leaks any of its natural gas liquids.
