Public Awareness

Residents along our pipeline rights of way, contractors, excavators, emergency responders and public officials all play a key role in pipeline safety. Through our Public Awareness Program, Columbia Pipeline Group raises awareness in the presence of our facilities, the importance of pipeline safety, and the understanding of the role our pipelines play in transporting energy. Our pipeline safety brochure can assist in learning how to prevent, detect and report a leak along a pipeline.

Frequently Asked Questions


How can I prevent damage of neighboring pipelines?

Anytime you plan to dig, do it safely by first calling your state’s one-call notification service. To reach your local one-call center, dial “811.” Every job entailing digging into the ground requires a call to your state one-call center, even for smaller projects such as planting trees or shrubs.

Once notified through the one-call service in advance of your work, we mark the location of our pipelines and rights of way and, then explain our construction guidelines. This free service allows you to begin your project with the assurance that your safety will not be compromised, and that our pipelines will not be damaged.

In addition to digging when else should I call 811?

Not only does the law require that people performing excavation to call 811 first, but anyone planning to cross pipeline rights of way with heavy equipment or perform blasting in the vicinity of any pipelines must contact the state one-call notification service.

What happens if I dig and disturb a pipeline?

Whether or not you’ve called 811 in advance, if you dig and expose or hit a pipeline or associated facility, contact us immediately. If you suspect gas is leaking also contact 911 to reach your local fire or police department. Even if the damage appears minor, it may cause a future safety problem. It is important that Columbia Pipeline Group inspects any potential damage.

How do I recognize a natural gas or natural gas liquids pipeline leak?
While leaks on interstate natural gas pipelines are rare, it is important to know how to recognize the signs of a leak if one were to occur in your area. Watch for one or more of the following signs:

Look For:

(Visual Signs of a Natural Gas Release)
• Dirt being blown or appearing to be thrown into the air
• Water bubbling or being blown into the air at a pond, creek, river or other wet areas
• Fire coming from the ground or appearing to burn above the ground
• Dead or dying vegetation on or near a pipeline right of way in an otherwise green area
• A dry or frozen spot on the right of way

(Visual Signs of a Natural Gas Liquids Release)

• The appearance of frozen ground over the pipeline
• Frost around aboveground piping
• The appearance of a high-velocity vapor jet near the exit point
• A vapor cloud having the appearance of a very thick fog

Listen For:

• A roaring, blowing or hissing sound

Smell For:

• A gas, petroleum or unusual odor which will sometimes accompany a pipeline leak

(Note that natural gas in some pipelines may not always be odorized.) 

Here’s what to do if you suspect a pipeline leak:

• If possible, safely turn off and abandon any motorized equipment you may be operating.
• Leave the area quickly.
• Warn others to stay away.
• From a safe place, call 911 to reach your local fire or police department, and call the pipeline operator’s 24-hour toll-free telephone number.

Here’s what NOT to do if you suspect a pipeline leak:

Do not touch, breathe or make contact with the suspected area. Stay upwind if possible.
• Do not use open flames or bring anything into the area that may spark ignition (cell phones, flashlights, motor vehicles, electric or cordless tools, etc).
• Do not attempt to operate pipeline valves.
• In the case of a fire, do not personally attempt to extinguish.
