Pipeline Safety

Leak

If you suspect a pipeline leak:

  1. Move away from the area immediately. Alert others to move away from the area. If indoors, move outdoors immediately.
  2. Call 911, once a safe distance from the leak.

Pipeline Safety Information

All pipelines are required to be marked along the pipeline. See the variety of types of markers for specific pipelines.

Remember that pipelines carry both gases and hazardous liquids. Along a right-of-way, you may see dead or discolored vegetation, pooled liquid; or a cloud of vapor or mist. You may smell an unusual odor, or the scent of petroleum or odorized natural gas. And you may hear an unusual hissing or roaring sound.

Regarding the NEXUS Pipeline in Green: the Nexus Pipeline is not odorized. However, other pipelines in the City of Green are odorized. If there is a leak, high pressure lines, similar to the size/pressure of the Nexus line in Green, will make a loud, roaring sound similar to the sound of a jet engine/freight train.
