Important Safety Information About Natural Gas Pipelines Near You
Q1. How do I know where gas pipelines are located?
The approximate locations of major natural gas pipelines can be found online at National Pipeline Mapping System or on the Southern California Gas Company (SoCalGas®) website. We also place pipeline markers next to our major pipelines near intersections or railway crossings.

Q2. Based on the population and location of pipelines, what is the designation for my City?

According to the U.S. Department of Transportation (DOT) guidelines, the City of Grand Terrace is designated as a Non-High Consequence Area (Non-HCA).

Q3. How can I make my City more safe and save resources by preventing pipeline incidents?
In 2011, there were 1 dig-ins in the City of Grand Terrace. Public officials are encouraged to work with contractors to have a valid 811 ticket before excavation. Contractors are required by California Law to call 811. However, homeowners are generally exempt.

Q4. Is my sense of smell good enough to recognize a gas leak?
Most of the time. However, there may be circumstances where you may not be able to smell the gas odorant, such as if you have a diminished sense of smell, the odorant is being masked by other odors or the odorant has been lost or reduced because of odor fade. Learn how your senses of sight and hearing can also alert you to the presence of a gas leak.

If a gas leak is detected, don't light a match, candle, or cigarette. Don't turn electrical appliances or lights on or off. Leave the area and from a safe location call us directly at (800) 427-2200 or 9-1-1.
