The Mariner East 1 pipeline sprung a small leak and spilled 20 barrels (~840 gallons) of ethane and propane in Berks County, near Philadelphia, on April 1 (see Mariner East 1 Sprang a Small NGL Leak Near Philly, on Apr 1). Sunoco Logistics Partners (i.e. Energy Transfer), builder and maintainer of the pipeline, shut it down and fixed it over the next several days. The Pennsylvania Public Utility Commission (PUC), which oversees regulation of the pipeline, has just (a year and a half later) “requested” Sunoco pay $225,000 for violating various state and federal regulations. It was an $11,250 per barrel spill.
