PUBLIC AWARENESS & SAFETY

Pipeline Location

There are four main types of pipelines: crude oil, liquid, gas and chemical. Most run underground, and are clearly identified by markers along routes that identify their approximate – not exact – location. Typically, markers are found where a pipeline intersects a street, highway or railway. Pipeline markers do not indicate depth or number of pipelines in the vicinity, and the pipeline may not follow a straight course between markers. Every marker provides the name of the operating company, the product transported, and an emergency contact phone number.

Types of Markers

  • Pipeline Marker: The most common marker, it contains operator information, product type, and an emergency contact number. They are typically yellow, black and red – but size, shape and color may vary.

  • Aerial Marker: Patrol planes that monitor pipeline routes use this skyward-facing marker.

  • Casing Vent Marker: This marker indicates that a pipeline (protected by a steel outer casing) passes beneath a nearby roadway, railway or other crossing.
