Recognizing a Leak

If a pipeline leak involving crude oil, natural gas or natural gas liquids occurs, you might see:

• Dirt being blown or appearing to be thrown into the air
• A white vapor stream or mist-like cloud over the pipeline
• Unexpected frost or ice on the ground
• Continuous bubbling in wet or flooded areas
• Dead or dying vegetation in an otherwise green area
• Discolored snow or vegetation
• A dry area in a wet field
• Flames coming from the ground or appearing to burn above ground
• Liquid on the ground
• Oily sheen on water surfaces

You might hear a roaring, blowing or hissing sound.

You might smell an unusual skunk or rotten egg odor.
