The Mariner East Pipeline system, including Mariner East 1 (ME1), Mariner East 2 (ME2), and Mariner East 2X (ME2X), completed construction and went online in the first quarter of 2022 (see All Construction for Mariner East 2 Pipeline Now Done, Online 1Q). Pipeline operators like Energy Transfer (ET), the builder and operator of the ME system, routinely inspect pipelines for potential troubles. They run a PIG (pipeline inspection gauge) down the pipeline to search for corrosion and anomalies. ET recently found an anomaly in the ME2X pipeline --- a dent --- in a section in Chester County, PA. So they've set about to fix it.
