How to Identify Pipelines

Pipelines are usually buried underground. The pipeline right-of-way is the land over the pipeline, usually 25 feet from each side of each pipeline.

Pipeline markers show the general, not the exact, location of a pipeline. They do not show how deep the pipeline is buried or how many lines are in the area. Pipelines may not follow a straight course between markers. Emergency contact information is listed on each pipeline marker.

  • Do not disturb the markers. Willful removal or damage of the markers is a federal offense and subject to a fine or imprisonment.
  • Never rely only on the presence or absence of pipeline markers. Someone may have moved or removed the marker.
  • Do not dig on the rights-of-way unless you have notified Explorer Pipeline.
  • Do not plant trees or tall shrubs and do not build permanent structures on the rights-of-ways, so that pipeline rights-of-way can be properly maintained.

Explorer Pipelines markers are easy to spot—just look for the black, yellow, and white signs.
