Excavation damage presents the most common threat to underground infrastructure in the pipeline industry. Improper excavation can result in serious risk to life, property and the environment. Using proper excavation practices can significantly reduce these risks, including the risk to buried assets.

Project Planning: The first step in a safe and efficient excavation project is proper planning of the project's location and scope. Care should be taken to identify the length, location and depth of the project prior to contacting 811. You should be prepared with the expected duration and the GPS location or street address for where the excavation activity will occur.

Making the One-Call:  After proper planning, you are required to contact 811 at least 72 hours prior to excavating. Tennessee 811 will then notify their member underground pipeline and other utilities in the area of your excavation. A representative from the facility owner will come to the site and mark their facilities, free of charge. When contacting 811, you should provide the one-call center with the following:

  • Company Name and Contact
  • Excavation site location and address - including county and city / community
  • Description of excavation activities
  • Special instructions helpful for marking the site or exactly where work will be conducted on the site
  • Estimated date when work will begin

Once the area is marked, it is the responsibility of the excavator to dig with care if they have to work within 24" of the marks. Come to your local gas safety and awareness meeting (PIPE) meeting to get more helpful information.

To identify the approximate location of their facilities, the facility owners will use the following color code.
