811 is a free one-call service managed by USA North. Call 811 at lease two business days before your planned digging project. USA North will contact PG&E and other utilities. Representatives of these utilities will then come out to locate and mark their underground lines.
Steps to Take Before You Dig
- Identify and mark the digging area with a white substance such as chalk, spray paint, flour or marking whiskers, tags, stakes or any combination.
- Call 811 at least two business days before you dig. Contractors are required by California state law to call.
- We use colored utility flags, stakes or paint to mark underground lines, following the American Public Works Association Uniform Color Code. Please leave the marks in place until you are finished digging.
- Use handheld digging tools when digging within 24 inches of the outside edge of any underground lines. After finishing your project, carefully backfill and compact the soil.

Signs of a Natural Gas LeakYour awareness and actions can be critical to the safety of your home and community. Please report any signs of a gas leak immediately by calling 1-800-743-5000.
Indications of a possible gas leak:
- Smell — We add a distinctive, sulfur-like rotten egg odor to natural gas, so you can detect even small amounts.
- Sounds — Pay attention to hissing, whistling or roaring sounds coming from underground or from a gas appliance.
- Sight — Be aware of dirt spraying in the air, continual bubbling in a pond or creek and dead or dying vegetation in an otherwise moist area.
