Mariner East 1 operations temporarily suspended

April 4, 2018 By    

The Pennsylvania Public Utility Commission (PUC) ordered Sunoco Pipeline LP to temporarily suspend operations of the Mariner East 1 pipeline over safety concerns.

Mariner East 1 is an 8-in. diameter natural gas liquids pipeline used to transport propane, butane and ethane from the Marcellus and Utica shale areas in western Pennsylvania, West Virginia and eastern Ohio to destinations in Pennsylvania, including the Marcus Hook industrial complex on the Delaware River, where they are processed, stored and distributed to local, domestic and waterborne markets. The PUC initially authorized an emergency order after sinkholes developed near the pipeline in Chester County, Pennsylvania.

The PUC wanted to ensure the integrity of the pipeline through testing and analysis before it’s placed back into service. One midstream company representative and propane supplier says the shutdown is backing up ethane and propane into the Marcellus and Utica shale region, causing a temporary oversupply in the local markets.
