The Mariner East 1 (ME1) natural gas liquids pipeline that flows ethane and propane came back online Monday (see Mariner East 1 NGL Pipe Restarts Today After Shutdown Since Jan.). It had been out of service for more than three months because a sinkhole exposed a few feet of bare pipe near Philadelphia. Good thing ME1 is back, because yesterday the Pennsylvania Public Service Utility (PUC) announced an investigation into a potential new sinkhole near a section of pipeline used for the Mariner East 2 pipeline in Delaware County.
