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

  • Natural gas pipelines and utilities must adhere to strict state and federal regulations. 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 Sunoco Pipeline projects.
  • 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
  • Sunoco Pipeline’s Integrity Management Program uses smart inspection technology and on-site inspections to assess every inch of pipeline it operates to ensure safe and efficient operation.
