Operators of gathering pipelines and natural gas transmission and hazardous liquid lines place permanent signs, called pipeline markers, along their pipeline routes at roadways and railway crossings and at aboveground facilities to identify the general location of pipelines. Pipelines maintained by your local gas company typically do not have permanent pipeline markers.
Markers can vary in size, shape and color, but all markers include important information about the pipeline, including the product transported, the pipeline operator’s name and the operator’s emergency contact number, to report pipeline problems. Line markers do not indicate the depth of the line, the number of lines in the area or the exact location of a pipeline.
Pipeline markers are important safety signs. It is a federal crime to willfully deface, damage, remove or destroy a pipeline marker. If you notice a damaged marker, or accidentally damage a marker, please contact the pipeline operator. See examples of different marker shapes.
