Because of recent sinkholes developing near the construction of the Mariner East 2X pipeline, Chester County, PA officials have sent a letter to the Pennsylvania Public Utility Commission (PUC) asking the agency to immediately shut down flows along the existing Mariner East 1 pipeline. All of the ME pipelines flow NGLs, mainly ethane (sometimes propane and butane). Officials say seven sinkholes have developed near ME construction *just this year* and they are concerned more sinkholes will develop and potentially crack or break an existing pipeline. One recent sinkhole swallowed a small tree (caught on video, below).
