03 The 811 process
Call
Contact the state One Call system before every digging project and confirm the required notice period.
Wait
Allow the full required time for affected underground utility operators to respond.
Locate
Trained personnel identify underground pipelines with painted markings, stakes or flags.
Respect
Preserve the marks and plan the excavation around the identified facilities.
Dig with care
Use appropriate excavation methods and remain alert for changing site conditions.
Pipeline markers
Markers show presence—not exact depth.
Above-ground markers indicate that an underground petroleum or natural gas pipeline is present in the area. They typically identify the operator and an emergency telephone number, but they do not show the exact location, depth or number of pipelines.
Always contact 811 before excavation rather than relying on markers alone.
Rights-of-way
Keep the route visible and accessible.
A pipeline right-of-way provides access for inspection, maintenance and emergency response. Report suspicious activity, construction or possible damage near a Chevron pipeline right-of-way.

Report every scrape, dent, gouge or disturbance.
Chevron advises that apparently minor damage to a pipe or its coating may create a future problem. The pipeline owner must inspect and repair any damage.
