Pipelines in the United States

Pipelines in the United States are regulated by each state or by the Pipelines and Hazardous Materials Safety Administration (PHMSA).

The general location of an Enbridge pipeline in your community can be determined by identifying the pipeline markers. The pipeline follows a right-of-way, which designates a safe and clear corridor for the pipeline. This right-of-way enables Enbridge workers to gain access to the pipeline for inspection, maintenance, testing or in an emergency.

For your safety and to protect the pipeline, certain activities – such as building permanent structures and planting deep-rooted shrubs and trees – are prohibited within the pipeline right-of-way.

Our pipeline markers are located at varying intervals along the right-of-way and typically on both sides of road crossings. All pipeline markers provide a telephone number for reporting pipeline emergencies and indicate the product being transported in that pipeline.

The placement of these markers indicates the general position of the buried pipeline and should never be used as a reference for the exact location of the pipeline. You may also find the general location of pipelines in your area and contact information for the pipeline operators through the National
Pipeline Mapping System

If you are planning to dig near any pipeline, it is important to follow the one-call procedure and not rely on pipeline markers or other information to determine the location of a pipeline. The one-call procedure must be used to properly locate pipelines and other buried utilities at a proposed excavation site.

More information about right-of-way standards in the United States is available by calling our right-of-way department:

(713) 821-2000 (Texas, Western Oklahoma, Arkansas, Louisiana and Mississippi)

(715) 394-1421 (Illinois, Indiana, Kansas, Michigan, Minnesota, Missouri, Montana, North Dakota, New York, Ohio, Eastern Oklahoma and Wisconsin)
