Locating Colonial Pipelines Near You

Because many pipelines, like Colonial’s pipelines, are buried underground, they may seem invisible. Actually, they are clearly marked by federally required pipeline markers.

Colonial posts easy-to-spot yellow, black and red markers along the pipeline route to show the approximate location of the pipeline. Markers are also posted at all locations where pipelines pass beneath roads, rivers, streams, and railroad tracks.


These markers identify Colonial Pipeline as the operator, list the product being transported, and display Colonial’s 24/7 emergency phone number.


It is a federal offense to move, remove or deface any pipeline marker. While markers show the “approximate” location of the pipeline, their placement within the easement does not show the “exact” location. To identify the exact location of a pipeline before digging, always call 811 to have your lines marked for free.


You can also view the approximate location of transmission pipelines and obtain contact information for pipeline operators in your area by visiting the National Pipeline Mapping System (NPMS).

Call Before You Dig
