Member facilities have three full working days, starting at 11:59pm the day the notice is given, to mark the locate area requested for their underground utilities or notify the excavator of no conflict in that area.

NC811 Video Toolbox

The width of the location tolerance zone includes 24 inches on each side of the utility plus the width of the utility itself. If you must dig within the tolerance zone, digging with caution by hand is recommended to help reduce the possibility of damage to the located utility. If a damage occurs, you will need to notify the facility owner directly, and you can dial 811 to enter a report of damage to underground facilities. In the event of a gas product release, please quickly and safely move up wind and dial 911 to report.

The contacted facility members shall identify their lines in either water soluble paint or flags in accordance with the American Public Works Association Uniform Color Code as follows: Electric Power Lines, Cables, Conduit and Lighting Cables are red; Gas, Oil, Steam, Petroleum or Gaseous Materials are yellow; Communication, Cable TV, Alarm or Signal Lines, Cables or Conduit are orange, Potable Water is blue, Sewer or Drain Lines are green and Reclaimed Water, Irrigation and Slurry Lines are purple. Please be aware that some facility members may indicate via telephone, fax, or email that their facilities are clear or that a representative needs to be on-site during excavation.

​Members are not responsible for marking private lines. Water, sewer and storm drain lines are marked within the right of way or to the meter, and not on private property. Lines from the right of way or meter to the residence or business are private lines and you will need to contact a private line locator to have these lines located. You must contact any non-member facility owners not listed on your location request directly to request their facilities to be located and marked.
