U.S. Information

In the U.S., 811 is the number to call before you dig. Calling 811 before every digging job gets your underground utility lines marked for free and helps prevent undesired consequences.

Before digging around or near pipelines, it's important to contact One-Call - the source for safe digging information. Mishaps can easily be prevented by knowing exactly where you should and should not dig.

Spectra Energy operates natural gas transmission pipelines in 26 states and participates in One-Call programs in all of those states. We encourage those who are going to dig or otherwise disturb the surface to call their state One-Call Center to report planned digging activities and allow us and other underground facility operators a chance to mark surface above the facilities before digging begins.

For more information on damage prevention and a list of state One-Call Center phone numbers, call toll-free (888) 258-0808 or see the Dig Safe website. If you are planning to dig on or near the pipeline right of way, please also see the Pipeline Markers, Damage Prevention & Right of Way section.

Spectra Energy is a sponsor of the Common Ground Alliance, a non-profit organization dedicated to shared responsibility in damage prevention to ensure public safety, environmental protection, and the integrity of services.

In the U.S., the quick and easy way to get the location of underground utilities marked in the vicinity where you plan to dig is by placing a free call to 811. This call is automatically forwarded to the state one call center for processing.

When Spectra Energy receives notification from a One-Call Center that someone intends to dig near our pipeline facilities, we send personnel to mark the location of the facilities in the vicinity of proposed digging or other earth disturbance activities. We also have company employees on-site when the excavation occurs.

Spectra Energy responds to numerous calls per day-helping excavators and contractors ensure that they work safely around our pipelines.

Spectra Energy mails information brochures to residents, businesses, potential excavators, public officials, and school administrators along the U.S. pipeline system each year to inform them of the presence of the pipelines and instruct them on how to recognize and react to unusual activity in the area. Our employees routinely meet with excavators and emergency response officials to educate them about Spectra Energy pipelines.
