National 811 Day efforts highlight the importance of contacting 811 before digging

CHATTANOOGA, Tenn. – Aug. 11, 2021 – Summertime is here, and for many homeowners, and that means do-it-yourself home improvement projects like planting a tree or installing a fence or deck.

Aug. 11 is National 811 Day, and Chattanooga Gas reminds residents and professional contractors across the region that the date serves as an important cue to always contact Tennessee 811 before starting any outdoor digging project.

“Safety is paramount for our team members, customers and the community,” said Paul Leath, regional director at Chattanooga Gas. “The danger of striking an underground utility is real, and making the simple call to 811 can protect your family and helps keep communities safe.”

The Common Ground Alliance, a national nonprofit organization working to protect underground utility lines, says damage to covered pipe and cable happens once every few minutes because of digging near unmarked utility lines. While large excavation projects often cause these mistakes, a homeowner’s simple mailbox installation or even a modest gardening project can lead to striking infrastructure that is right underground.

Whether a homeowner with a shovel or a professional excavator with an earthmover, Tennessee state law requires a call to 811 at least three business days before starting any digging project. Chattanooga Gas more approximately 1,700 miles of underground natural gas pipeline along with other utility companies’ underground communication cables, water and sewer lines. Knowing the location of underground utilities helps prevent injuries, property damage and inconvenient service outages.

When homeowners and contractors connect with Tennessee 811 it notifies the appropriate utility companies of the intent to dig. Professional locators are then sent – for free – to the requested dig site to mark the approximate locations of underground lines with flags, paint or both.

Chattanooga Gas encourages homeowners and contractors to follow these safe digging guidelines and always dig with CARE:

  • Call or Click Before You DigBefore starting any outdoor digging project, customers should dial 811 or visit at least three days in advance to request to have underground utility lines marked. Requests to have utility operators locate underground lines, including natural gas, electric, water, sewer, telephone and cable lines, can be made 24-hours a day, seven days a week. The service is free. 
  • Allow the Required Time for Marking: After contacting Tennessee 811, wait for underground utility lines to be marked before digging. Locators will mark the approximate location of buried lines with color-coded spray paint, flags or stakes corresponding to the utility. The color used for natural gas is yellow. 
  • Respect the MarksOnly use hand digging tools to carefully uncover the area around a utility line when you need to dig near location markers.
  • Excavate CarefullyMake sure the marks remain visible during the project. If the lines are damaged or removed, customers are encouraged to contact Tennessee 811 to have lines remarked.

If a natural gas line is damaged accidentally or the distinctive rotten-egg odor associated with natural gas is present, call 911 or the Chattanooga Gas 24-hour emergency phone line at 1-866-643-4170 from a safe location. Do not operate any machinery or equipment that might cause a spark or create an open flame.
