Pipeline leaks are rare, but they can be dangerous.  A damaged pipeline may release flammable products into the soil, air, or water that can be harmful to people and the environment.  It is important that you know how to quickly identify and respond to a potential pipeline leak.

Use your sense of sight, sound and smell to identify a potential pipeline leak.  Signs of a potential pipeline leak include:

  • A pool of liquid on the ground

  • A rainbow sheen on water

  • Dead or discolored vegetation

  • Continuous bubbling in water

  • Dirt or water being blown into the air

  • A dense white cloud or fog

  • An unusual hissing or roaring noise

  • An unusual odor such as gasoline, oil, sulfur or a rotten egg smell

Products transported in pipelines can be odorless.  Use your sense of sight and sound as well as smell to identify a potential leak.

If you suspect a pipeline leak:

  • Leave the area immediately in an upwind direction and warn others to stay away

  • If you are near a school, hospital or large business, evacuate individuals from the area immediately as outlined in your emergency response plan

  • Do not light a match, start an engine, use a cell phone or turn on/off any electrical devices

  • Once you are a safe distance away from the potential leak, use a telephone or cell phone to call 911 and Marathon Pipe Line LLC at 1-800-537-6644

  • Do not drive into an area where you suspect a leak, and do not touch or operate pipeline valves
