Duke Energy and Piedmont Natural Gas are encouraging people to call 811 before starting any outdoor digging projects. The reminder comes as Aug. 11 marks National Safe Digging Day, an event focused on preventing damage to underground utility lines.
The 811 service is a nationwide, toll-free number managed by the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA). It requires anyone planning excavation work—including contractors, homeowners, and business owners—to call at least three business days before digging begins. After calling, local utilities will send crews to mark the locations of underground lines such as electric, natural gas, water, sewer, phone, and cable TV with stakes, flags or paint.
Between January and June 2025, Duke Energy and Piedmont reported over 5,000 incidents of damage to underground electric and natural gas lines across their service territories in North Carolina, South Carolina, Florida, Ohio, Kentucky, Tennessee and Indiana. Of these incidents, about 1,450 involved damages to underground natural gas facilities in North Carolina, South Carolina, Tennessee, Ohio and Kentucky. Duke Energy also reported around 3,600 cases of damage to its underground electric network during this period. In total for 2024 alone, more than 8,870 damages were recorded by both companies.
Brian Weisker, senior vice president and president of Duke Energy’s natural gas business said: “Whether you’re finishing a summer yard project or starting something new this fall, call 811 before you dig. Damaging a utility line can be dangerous and costly, but it’s easily prevented by this simple step. Safety and reliability start with contacting 811.”
