Independent Report Endorses Safety of Mariner East 2

Project’s use of 12-inch pipeline meets or exceeds safety regulations, Accufacts reports

An independent analysis compiled for West Goshen Township in Chester County on the use of a 12inch pipeline on Mariner East 2 concludes that the pipeline builder meets and exceeds a number of requirements of the federal pipeline safety regulations, and that the project meets or exceeds the prudent technical approaches commensurate with the safe transportation of natural gas liquids. West Goshen released the report at a recent meeting.

The report was compiled by Accufacts Inc., which has more than 40 years of experience in the energy industry and is run by a certified safety management engineer with a special focus on proper design and operation in areas of unique population density or of an environmentally sensitive nature. The full report is available here.

This is not the first report the township has commissioned to determine the safety of the pipeline. In a January 2017 report for West Goshen Township, Accufacts endorsed the Mariner East 2 section of line in Chester County. Accufacts President Richard Kuprewicz reached similar conclusions in an earlier report about the existing Mariner East 1 line.

All of these findings mirror the U.S. Department of Transportation’s Pipeline Hazardous Materials Safety Administration’s determination that identifies pipelines as the safest mode of energy transportation.

Safety, Security and Environmental Stewardship

These are core values at Sunoco Pipeline, and we are dedicated to safe operation of our pipeline systems.

Safety

Sunoco Pipeline is committed to safety at the highest level. The U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration, the Pennsylvania Public Utility Commission and other government agencies strictly regulate the manufacturing, construction and operation of all Sunoco Pipeline projects. Sunoco Pipeline meets, and exceeds when possible, all federal safety standards for the construction and operation of pipeline projects. 

Additionally, Sunoco Pipeline employs the most advanced methods of leak detection, integrity management and damage prevention to minimize the risk of a release and ensure minimal to no impact on individuals, businesses and the environment adjacent to our pipelines. Certified controllers closely watch the pipeline’s pressure, temperature and flow in real time — 24 hours a day, seven days a week — from a control center dedicated exclusively to the safe operation of our pipelines.

Our pipelines have been studied and tested to ensure optimal safety for residents and businesses located within close proximity of those pipelines.

Sunoco Pipeline is part of the Energy Transfer family of companies. The combined Energy Transfer family owns and operates approximately 71,000 miles of pipeline, and we employ best management practices in the design, fabrication and systematic testing and inspecting of our pipelines and our facilities. We adhere to a strict integrity management and maintenance program in all of our operations to ensure that our network meets or exceeds the requirements of all federal and state regulatory agencies.


Separating Fact from Fiction

The Greater Philadelphia region has coexisted for generations with pipelines carrying natural gas and natural gas liquids such as propane. Here are some facts about the Mariner East project that will inform you about this energy infrastructure project.

Pipeline Construction: Know the Facts

  • Skilled local tradesmen, including members of unions such as Philadelphia-based Steamfitters Local 420, are equipped with the most advanced training, safety measures and operation standards to ensure safe and environmentally responsible construction.
  • Sunoco Pipeline is using advanced construction methods, such as horizontal directional drilling, to minimize environmental impacts.
  • Mariner East 2 will use over 75,000 tons of domestic steel coated with a specialty epoxy to prevent corrosion and other damage. Sunoco Pipeline does not use PVC, copper or aluminum.
  • In 2015 and 2017, a Chester County township commissioned an independent study, which found that Sunoco Pipeline meets or exceeds federal safety requirements at every level:
    • Using additional integrity-management approaches
    • Prudent pump-station design, mainline valve placement and actuation
    • Pipeline monitoring and control-room procedures
    • Automatic release-detection safety systems
    • Implementing emergency-notification protocols that reflect the care that transporting natural gas liquids requires
