The Different Ways Range and CNX Dealt with ME1 Pipeline Outage

Now that the Mariner East 1 (ME1) NGL (natural gas liquid) pipeline is back up and running, Marcellus/Utica producers are breathing a sigh of relief–at least, Range Resources, the primary customer for the pipeline, is. Following sinkholes that developed while Sunoco Logistics Partners was drilling for the Mariner East 2 (ME2) project, a portion of ME1 was exposed to open air in Chester County, PA, which prompted the state Public Utility Commission to shut down ME1 in early March (see PA PUC Shuts Down Mariner 1 Pipeline Due to Mariner 2 Sinkhole).
