Pipeline Safety

Pipelines are the safest mode of transportation. In fact, the latest data reveals 99.999997 percent of all gas moves safely though interstate natural gas transmission pipelines.

Over the years, the reliability of pipelines has led to 50 percent of Pennsylvania homes and 75 percent of those in New Jersey choosing natural gas for home heating. PennEast will help these households and future customers enjoy the benefits of abundant local natural gas, while putting safety first every step of the way.

Safety is PennEast’s highest priority. When constructing and operating the PennEast Pipeline, PennEast will adopt design features and practices that meet or exceed stringent pipeline industry and regulatory standards. This includes testing welds, using state-of-the-art corrosion protection systems, regular leak surveys and 24/7 monitoring.

  • Federal Energy Regulatory Commission (FERC) inspectors, in addition to independent, third-party inspectors hired by the FERC will be on site throughout pipeline construction to ensure overall safety, compliance with permits, regulations and industry best practices.
  • A special coating to prevent corrosion will be placed inside and outside the high-strength, carbon steel that forms the pipeline.
  • Prior to being placed into service, PennEast will conduct an X-ray of all welds and a hydrostatic pressure test will be conducted at pressures that well exceed the maximum allowable operating pressure (MAOP) to ensure all welds can tolerate the designed operating pressures.
  • PennEast’s Gas Control Center will continuously monitor 24/7 gas pressure and flow in the pipeline.
  • In addition to meeting or exceeding the minimum requirements of Main Line Valve (MLV) spacing specified by PHMSA, PennEast will install remotely operated valves at each new MLV site.
  • PennEast will train and coordinate with first response agencies along the Project route, starting with communicating construction plans and expanding into training and coordination during ongoing operations.

Pipeline Maintenance

To ensure a safe, efficient and reliable system, maintenance inside the pipeline is as important as maintenance outside the pipeline. This is why PennEast will implement a systematic approach to pipeline integrity management, including in-line inspections, throughout operation of the line.
