Crews work to stabilize sinkholes in a West Whiteland Township neighborhood on March 3. The sinkholes appeared recently near a construction site for the Mariner East 2 pipeline.
(State Impact PA) – Pennsylvania’s Public Utility Commission on Wednesday ordered a temporary shutdown of the Mariner East 1 natural gas liquids pipeline, saying it could have a “catastrophic” effect on public safety if it leaks.
PUC Chairman Gladys Brown approved a request by the commission’s Bureau of Investigation and Enforcement for an emergency order that would halt operation of the line until inspectors are satisfied that it meets safety standards.
The panel, in a petition issued earlier Wednesday, argued that the pipeline had been exposed by the appearance of sinkholes near the construction of two other pipelines – Mariner East 2 and 2X – at several places in Chester County’s West Whiteland Township in recent days.
