Although pipelines are the safest mode of overland transportation, it is critical to be mindful of proper procedures that should be used when responding to a pipeline emergency.

Identifying the pipeline:

  • Check for pipeline markers posted nearby. (Caution! The pipeline marker may not show the exact location of the underground pipeline.)
NuStar operates pipelines under the following names:
  • NuStar Logistics, L.P.
  • NuStar Pipeline Operating Partnership L.P.
  • NuStar Terminals Operations Partnership L.P.
  • Shore Terminals LLC
  • ST Linden Terminal, LLC

Recognizing a leak:

By Sight: A pool of liquid on the ground near a pipeline, a dense white cloud or fog over a pipeline, or discolored vegetation surrounding the pipeline may be signs of a leak.

By Sound: An unusual noise coming from the pipeline, like a hissing or roaring sound, may be a sign of a leak.

By Smell: An unusual smell may accompany a pipeline leak.

What to do if you suspect a leak!

  • Leave the leak area immediately.
  • Do not touch, breathe, or make contact with leaking liquids.
  • Do not light a match, start an engine, use a telephone, switch on/off light switches or do anything that may cause a spark in the area or vicinity of the leak.
  • From a safe location immediately call 911 and the NuStar Pipeline Control Center at 800-481-0038 and report exactly what you have seen, heard or smelled and where this incident or event took place.
  • Warn others but do so without entering or re-entering the area where a pipeline leak is suspected.
  • Do not drive any vehicle into a leak or vapor cloud area.
  • Do not attempt to operate any pipeline valves yourself.
  • Do not attempt to extinguish a petroleum product or natural gas fire. Wait for local firefighters and other professionals trained to deal with such emergencies.
