Pipeline Safety                     


Protecting the safety of our employees and our communities is our top priority.

That is why under strict state and federal oversight, we use multiple, overlapping layers of protection at every stage of the project to ensure public safety. In many cases safety measures will go well above and beyond regulatory requirements because that's how we do business, and we believe it's the right thing to do.

For us, this is a deeply personal commitment to the communities we call home. That's because our employees and contractors live in the communities where the pipeline will be built and operated. For many of us, our roots go back generations. So our commitment to safely building and operating the Atlantic Coast Pipeline is more than just a professional commitment; it's a promise we make every single day to our own friends, families and neighbors.

To ensure the protection of public safety, we use redundant and overlapping safety measures at every stage of the project.

Construction safety                         


  • The pipeline will be built with nearly 1/2 to almost 1-inch thick steel pipe and a protective layer of epoxy coating, which provides an inherent defense against corrosion and other damage.
  • Before going into service, we inspect each weld along the entire length of the pipeline with x-ray equipment to make sure each weld is totally secure.
  • After welds are inspected for integrity, the entire pipeline is pressure tested with water at up to 1.5 times the maximum operating pressure, another important way we make sure the pipeline and welds are totally secure.

    Operational safety                         


    • The pipeline is closely monitored 24/7, 365 days a year, at Dominion Energy's Gas Control Center. At all times we monitor the pressure, temperature and flow of gas through remote sensors positioned along the entire length of the pipeline.
    • Our vigilant, around-the-clock monitoring allows us to detect and address even the slightest variation before it becomes a risk to public safety.
    • The pipeline and all facilities are inspected by aerial observation and by foot patrol on a regular basis.
    • The interior of the pipeline is also inspected through the use of sophisticated devices known as smart pigs, which use computerized sensors to detect dents, corrosion and other damage and allow us to make immediate repairs when necessary to ensure the integrity of the pipeline.
    • The pipeline is equipped with remote-controlled shut off valves, which allow gas control operators to immediately shut off the flow of gas to individual sections of pipeline if any safety issues are detected.
    • All operational employees must meet strict government-mandated qualification standards and receive safety training on a regular basis.

      Working with first responders                         


      • We work closely with local first responders in every community where the pipeline is operated to ensure they are fully trained and equipped to respond in the event of an incident or emergency.
      • We provide annual training to all local first responders, including emergency preparedness exercises and other drills.
