Economic Benefits of Mariner East Pipeline

Pennsylvania Manufacturers’ Association Statement on Economic Benefits of Mariner East Pipeline

Statewide Trade Group Welcomes Positive Economic News Documented by New Pipeline Study

The Pennsylvania Manufacturers’ Association today heralded the findings of a new economic impact report by Econsult Solutions, an economic consultancy based in Philadelphia, which shows the Sunoco Logistics’ Mariner East natural gas liquids projects would add $4.2 billion to the Pennsylvania economy.

“Pennsylvania’s manufacturing sector is poised for a new era of expanded growth utilizing our abundant energy resources.  New investments like the Mariner East projects demonstrate the growth that can be realized by repurposing the former Marcus Hook oil refinery into a regional energy hub,” said PMA Executive Director David N. Taylor.  “This new study finds that ongoing annual economic benefits from the Sunoco Logistics’ Mariner East projects’ would be between $100 million and $150 million, supporting up to 440 jobs with earnings of $22 million to $33 million. 

“The Mariner East projects can be the catalyst for a new energy future for Pennsylvania, serving as a magnet for expanded investments along America’s East Coast.  The long-term availability of low-cost and reliable gas liquids as a key feedstock for multiple manufacturing processes is a game changer for the state’s economy.  These projects are essential for connecting Pennsylvania to a more prosperous future.”

The Econsult report references a recent PricewaterhouseCoopers study on the potential impact of shale gas on U.S. manufacturing.  The PwC report finds that, by 2025, shale gas could add more than one million workers to the U.S. manufacturing industry and allow U.S. manufacturers to lower their raw materials and energy costs by as much as $11.6 billion annually.
