Call 811 Before You Dig


Be careful where you dig: It’s FREE and easy to prevent damage to natural gas pipelines

Excavation, boring, tunneling, backfilling or other construction activities often cause damage to our gas lines. In the state of Tennessee, State Law requires anyone about to engage in either digging, excavation, moving of earth, demolition or any type of activity that disturbs the earth and therefore involves a danger to damaging underground utility lines, to notify Tennessee One Call, of their intent to dig at least 3 working days (excluding weekends and holidays) prior to beginning their work. 

One Call is a nationwide free service that works with pipeline operators to mark the location of underground lines. When you dial 811, pipeline operators are notified and will mark the location of gas pipelines with yellow marker flags. Other underground utility lines, including water and sewage will be marked with different color flags. Locate requests are valid for 15 calendar days.

• CALL 811 72-hours prior to excavation, excluding weekends and holidays.

• WAIT the required time for operators to respond to your request.

• CONFIRM that all affected utility operators have responded to your request.

• RESPECT the marks. Preserve and protect markings throughout your project.

• DIG CAREFULLY. Maintain a “tolerance zone” of 24 inches on either side of the marked facility. Depth is not indicated. Hand digging to expose marked line is recommended.

Always call 811 before you dig! It’s the law!  For more information about the One Call system in Tennessee visit Tennessee 811 can clarify any questions you might have regarding the law and outline helpful guidelines and procedures of excavation.
