Nothing is more important than safety.
For us, this is a deeply personal commitment, because our employees and contractors live in the communities where the pipeline will be built and operated. So, our commitment to safety is more than just a professional commitment; it's a promise we make every single day to our own friends, families and neighbors.
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 our safety measures go well above and beyond regulatory requirements, because that's how we do business, and we believe it's the right thing to do.
The industry’s vigilant focus on safety is the reason underground natural gas pipelines are the safest form of energy transportation in the country – far safer than transporting other fuels by truck or rail. In fact, according to the most recent statistics available, more than 99.9 percent of all the natural gas transported through our nation’s pipelines was delivered safely and without incident.
- We will use only the highest quality materials to build our pipelines. All materials must meet strict specifications.
- The pipeline will be built with over 1/2-inch thick steel pipe and protective coatings, which provide an inherent defense against corrosion and other damage.
- Before going into service, we inspect each weld with x-ray equipment to make sure each weld is 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 secure.
- Hundreds of inspectors will be on site every day during construction, to ensure every phase of construction meets the requirements and conditions of the various permits that will apply to the project.
- 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 via remote monitoring devices 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 an issue and a potential risk to public safety.
- The pipeline and all facilities are inspected by aerial observation and by foot patrol on a regular basis.
- External corrosion is controlled through the application of a protective coating, and the use of cathodic protection.
- The interior of the pipeline is also inspected using sophisticated devices known as smart pigs, which use computerized sensors to detect dents, corrosion or other damage and allow us to make 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.
- 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.
