Our pipeline is a safe, reliable and efficient pipeline for transporting natural gas. As part of our commitment to ensure safety and operational efficiency, regular surface patrols are conducted to identify leaks and other factors that might affect the pipeline’s operation. While strict engineering standards have been followed in the design, testing, installation and maintenance of our pipeline, outside forces and adverse soil conditions can cause damage allowing gas to escape. Natural gas cannot be seen, nor can it be smelled unless treated with an odorant. To improve safety, we add a harmless chemical giving the gas a distinctive odor of ‘rotten eggs.’ This increases everyone’s ability to detect even the smallest gas leak should one occur.

We ask for your help in identifying possible gas leaks and reporting any activity on or near our rights-of-way which might cause damage to our pipeline.

The following are telltale signs of a leak on
or near the pipeline:


  1. 1.‘Rotten egg’ odor or petroleum odor
  2. 2. Hissing sounds or shrill blowing/roaring noises
  3. 3. Dirt or water being blown or thrown into the air
  4. 4. Bubbles appearing on the surface of water
  5. 5. Patches of brown vegetation in a green field
  6. 6. A dry spot on a moist field.

Additionally, you should:

  1. 1. Shut down and abandon any equipment being used near the suspected leak
  2. 2. Avoid open flames or other ignition sources, including motor vehicles
  3. 3. Evacuate the area
  4. 4. Do not operate any pipeline valves
  5. 5. Do not breath in the gas
  6. 6. Move upwind of the suspected leak
  7. 7. Call us immediately at 1-888-497-5665.

Additionally, we will:

  1. 1. Shut down the pipeline and isolate the problem
  2. 2. Identify hazards
  3. 3. Excavate and repair the damaged pipeline


    Since natural gas pipelines are buried underground, signs and line markers are used to indicate the approximate location of the pipeline along the route. Our pipelines are well marked at road and railway crossings, ditches, and rivers and creeks with yellow markers as shown here. The markers display the material transported in the pipeline, the name of the pipeline operator, and a telephone number where the operator can be reached. Installation of pipeline markers is mandated by federal law and landowners should ensure that all pipeline markers are protected and maintained at all times.
