Location of Pipelines

Pipeline rights-of-way are often recognizable as corridors that are clear of trees, buildings, or other structures. Keeping trees, shrubs, buildings, fences, and other structures away from the right-of-way ensures pipeline integrity and safety are maintained.

Pipeline markers are located in the pipeline right-of-way and vary in shapes, colors, and sizes. Markers indicate the approximate location, but not the depth, of a buried pipeline. These markers display the product transported in the line, name of the pipeline operator, and telephone number where the operator can be reached in the event of an emergency. Pipeline markers may also be found at road crossings, fence lines, and street intersections.

Right-of-Way Encroachments

Some activities may require you to work or use a pipeline right-of-way, including constructing temporary structures or using the right-of-way for the passage of equipment. This is known as encroachment on the right of way. Contact the pipeline operator before beginning any activity involving a right-of-way. In addition to calling 811, provide the pipeline operator with the following information: proposed activity, location of activity, and equipment to be used, including axle load weight.
