The developer of the Mariner East 1 natural gas liquids pipeline told the Pennsylvania Public Utility Commission’s Bureau of Investigation and Enforcement it intends to restart the pipeline today, Kallanish Energy reports.
Sunoco Pipeline LP plans to again ship natural gas liquids across southern Pennsylvania via the 88-year-old repurposed pipeline, which has been out of service since Jan. 20, when a sinkhole exposed several feet of the line in Chester County.
The 8-inch Mariner East 1, and the larger twin Mariner East 2 pipelines being built alongside it, have been forced to stop and restart operations or construction work several times in the past two years as regulators responded to spills, ground subsidence and water supply disruptions.
Sunoco, a division of Texas-based Energy Transfer LP, gave regulators notice on Friday of its plans to restart the pipeline. The owner will also take a series of additional steps to address safety concerns regarding the Mariner East pipelines, according to the Puc.
The pipeline moves up to 70,000 barrels per day of ethane and propane across Pennsylvania to Marcus Hook, near Philadelphia.
Mariner East 1, 2 and 2X are lines designed to carry natural gas liquids from the Utica and Marcellus shale plays to ports on the East Coast.
Mariner East 1 originally was built to flow gasoline from east to west across Pennsylvania. It was repurposed in 2014 to move propane from west to east. Then, in 2016, ethane was added to the products moving east.
