Dig Notification Can Avoid
Pipeline Strike Accidents

Pipeline strikes, inadvertent or not, are potentially deadly – and must be avoided. Contractors who plan to dig or excavate are required to call 8-1-1 and, at least two days beforehand, coordinate with either the Underground Service Alert of Northern California (known as USA North) or Underground Service Alert of Southern California (aka DigAlert).

You must call 8-1-1 at least two working days, but not more than 14 days, before starting your dig. You are not allowed to dig during that time.

You will be given a ticket number that references your dig information. Each contractor must have his or her own number. Sharing a ticket among contractors on a single job is not allowed. Tickets are valid for up to 28 days after they're issued.

Once the call is made, accurately outline your excavation area. Utility company representatives will visit within two working days either to mark or stake the horizontal path of their underground lines, provide information about the location, or advise whether there are lines in conflict with your project. Hand excavation may be required when digging around underground facilities.
