Look for Pipeline Markers

Look for these signs: White posts with bright yellow warning signs. Our pipelines are buried underground. These posts are used to show the approximate location of the pipelines. Look in road rights-of-way, at intersections, and along fence lines. Check today for pipeline markers posted nearby or on your property, or in your neighborhood, or at a work location.
You should be aware of any markers in and around your neighborhood or work location. Write down the name and phone number of the pipe line company listed on the marker and keep it in a safe place in case of an emergency involving the pipeline.
