How do I identify your pipelines?

Most pipeline right-of-ways are clearly identified with line markers. A pipeline right-of-way is a strip of land that usually varies between 25 to 150 feet wide depending on the size the buried pipeline. This strip of land enables workers to gain access to the buried pipeline for effective surveillance. Restricting building or digging in the right-of-way protects the landowner and the community through which the pipeline passes. The right-of-way can exist in many different kinds of terrain, from river crossings and cultivated fields to urban areas.

Pipeline marker

Pipeline Marker: Pipeline markers are used to notify the public of pipelines located in the area. They also provide the company name, product and contact number of the company operating the pipeline.

Aerial marker

Aerial Marker: Patrol airplanes can pinpoint locations along a pipeline using skyward-facing aerial markers like these.

Casing vent marker

Casing Vent Marker: This marker is used where a pipeline, projected by a steel outer casing, passes beneath a roadway, rail line or similar crossing.


NOTE: Willful removal or damage of markers is a federal offense and subject to a fine and/or imprisonment.
NOTE:
Some smaller pipelines may not be specifically marked but are obvious by the right-of-way.
