Line Markers for Pipelines

In accordance to Federal Regulations pertaining to Line Markers for mains and transmission lines a Line Marker must be placed and maintained as close as practical over each buried main and transmission line. This includes providing a Line Marker at each crossing of a public road and railroad. A Line Marker is necessary to identify the location of the transmission line or main to reduce the possibility of damage or interference. For pipelines aboveground a Line Marker must be placed and maintained along each section of a main and transmission line that is located aboveground in an area accessible to the public. The wording on the Line Marker must be legible on a background of sharply contrasting color. The word “Warning,” “Caution,” or “Danger” followed by the words “Gas (or name of gas transported) Pipeline” all of which, except for markers in heavily developed urban areas, must be in letters at least 1 inch high with 1/4 inch stroke. The name of the operator and the telephone number (including area code) where the operator can be reached at all times.
