May 03, 2018 06:55 pm

Energy Transfer Partners, L.P. (NYSE: ETP) announced today that its subsidiary, Sunoco Pipeline L.P. (SPLP), received a unanimous vote from the Pennsylvania Public Utility Commission (PUC) to resume operations of its Mariner East 1 pipeline. SPLP has worked diligently with the PUC’s I&E Division and their outside experts on the matter for several weeks and is pleased that all investigations concur regarding the safety and integrity of the pipeline. The procedures to resume public utility service on the pipeline will begin immediately.

Mariner East 1 is a major transporter of propane in Pennsylvania, which is ultimately delivered to local communities, providing affordable fuel to heat homes and run businesses. When Mariner East 1 was shut-in as a precautionary measure, there were no issues with the pipeline, which has been safely operating for decades. Its continued safe operation has now been verified by all parties.

Mariner East 1 is part of a larger public utility system including the Mariner East 2 and Mariner East 2X pipelines, which are currently under construction. Mariner East 2 mainline construction is 98% complete and 93% of the HDDs are either complete, in-progress or have been released for restart. Mariner East 2 is a critical energy infrastructure project, not only for Pennsylvania’s economy, but for the thousands of people it puts to work every day. The total potential economic impact from all Mariner East construction in Pennsylvania is estimated to be more than $9 billion, supporting approximately 9,500 total jobs each year over six years of construction, with estimated wages of nearly $3 billion. These projects provide an economic boost in the 17 counties where they are located and across the entire Commonwealth.
