Know What’s Below. Call 811 Before You Dig.

Phillips 66 proudly supports April’s Safe Digging Month and National 811 Day. By promoting the use of 811, these campaign initiatives aim to prevent accidental damage to underground utility lines, which can lead to costly repairs, service disruptions, and even serious injuries.

By calling 811 or visiting 811 before any excavation, you can ensure that you are aware of any underground utility lines in the area. This not only helps prevent costly damages, but also ensures the safety of yourself and those around you. It has been found that calling 8-1-1 before digging increases one’s chances of avoiding incidents, injuries, environmental harm, and event death.


We take a holistic approach to safety at Phillips 66, which involves prevention, maintenance, and emergency preparedness measures. Our company believes in the importance of continuous education and transparency when it comes to preventing pipeline incidents. We strive to keep our stakeholders informed about our pipelines and our policies, and we encourage an open dialogue to address any concerns or questions to prevent accidents and prioritize the safety of our communities and the environment.

811 is a national call-before-you-dig phone number that connects individual to a central call center where they can provide information about their excavation project.  Whether the project is small or large, there is no limit. Anyone who plans to dig must contact their states 811 a few days before the digging project. The call center then notifies the appropriate utility companies to come and mark the location of their underground lines. You may begin digging once you have confirmed all utilities at your worksite have been confirmed and your states recommended wait period has passed. It’s important to always call 811 before digging to ensure the safety of yourself and others, as well as to avoid potential fines or repairs. For more information, click below.
