Pipeline markers are located along the pipeline route, at road and railroad crossings and at all aboveground facilities.

Markers identify the general area but not the exact location or depth of the pipeline. They specify the type of product transported, the operator’s name and an emergency contact number.

The federal government also provides maps that show the approximate location of transmission pipelines in your community through the National Pipeline Mapping System.

Government and safety officials can access additional information and download electronic files to import into emergency preparedness GIS mapping systems.

To view maps visit the National Pipeline Mapping System. Government and safety officials can also request an electronic data file.
