In April 2017 (almost three years ago) the Mariner East 1 pipeline sprung a small leak and spilled 20 barrels (~840 gallons) of ethane and propane in Berks County, near Philadelphia. Sunoco Logistics Partners, builder and maintainer of the pipeline, shut it down and fixed it over the next several days. Yesterday the Pennsylvania Public Utility Commission announced a “settlement” with Sunoco, to fine the company $200,000. Sunoco, as part of the settlement, must also conduct a “remaining life” study of the pipeline. After all, it is almost 90 years old.
