If your company does excavation work, or if you are a homeowner or farmer who occasionally digs on your property, we need your help in preventing pipeline emergencies. Statistics indicate that damage from excavation-related activities, particularly from equipment digging into pipelines, is a major cause of pipeline accidents. Without proper coordination, excavation activities in the vicinity of underground pipelines can result in very dangerous situations.

Before undertaking any work, contractors and landowners have a duty to call to locate any utilities buried beneath the work site. In fact, it's the law.

1. Call 811 at least two working days (3 days in Michigan, Pennsylvania and Tennessee) before excavation is scheduled to begin. Provide the operator with the following information –
   • The address or location of the planned excavation
   • The nearest cross street
   • The distance and direction off the road
   • The date excavation is scheduled to begin
   • The type of work
2. The One-Call Center will notify the appropriate utility companies to mark the locations of their underground facilities.
3. Wait the required number of days
4. Trained technicians will mark the location of the underground utilities at no cost to you.
5. Respect the marks and dig with care.

Even if you cause what seems to be only minor damage to the pipeline, notify the pipeline company immediately. A gouge, scrape, dent, or crease to the pipe or coating may cause a future problem. It is imperative that the pipeline owner inspect and repair any damage to the line or coating. Click here for a complete listing of contact numbers.
