Pennsylvania state regulators on Friday issued a notice of violation to Energy Transfer Partners' Sunoco Mariner East 2 natural gas liquids pipeline after the company notified the department that it had released drilling fluids into a stream.
Energy Transfer Partners told the Pennsylvania Department of Environmental Protection that it released about 50 gallons of fluid into the Snitz Creek on Thursday while drilling underneath it in West Cornwall Township.
This incident marks the pipeline company's third inadvertent release of fluid into the Snitz Creek after one spill in August 2017 and another in September 2017.
The DEP said it would need to give Energy Transfer Partners its approval before drilling could begin again at the site.
The Mariner East 2 is designed to expand the total capacity of the Mariner East project to 345,000 barrels per day. Mariner East 2 is expected to be complete by the end of Q2 2018.
