Locating Pipelines

If you look closely along highways, roads, public servitudes and right-of-ways, you are likely to notice various above ground markers. Yellow markers usually indicate a pipeline system that carries either gas or liquid materials. Pipeline markers indicate the approximate location of pipelines and can include the name of the pipeline operator, the substance in the pipeline, warnings signs, aerial patrol markers, casing vents and 24-hour emergency contact information.

If you notice any pipeline markers in your neighborhood, write down the name and phone number of the pipeline company listed on the marker in case of an emergency. To identify pipeline operators in your area, visit the National Pipeline Mapping System at www.npms.phmsa.dot.gov.
