Pipelines are marked by above-ground signs to indicate the approximate location, product carried and the name and contact information of the company that operates the pipeline. Pipelines are located in areas called a right-of-way (ROW) and these ROW's are often recognizable as corridors that are clear of trees, buildings or other structures except for the pipeline markers. Markers do not provide information on the depth or number of pipelines in the vicinity and do not indicate the exact position of the pipeline. Also, pipelines may not follow a straight path between markers.
To identify pipelines, look for the line markers like those shown below. The signs are generally yellow, black and red in color. We install markers at roads, rail and river crossings, and other places along the right of way.
