N.C. Gen. Stat. § 87-116

The General Assembly of North Carolina hereby declares as a matter of public policy that it is necessary to protect the citizens and workforce of this State from the dangers inherent in excavating or demolishing in areas where underground lines, systems, or infrastructure are buried beneath the surface of the ground, and it is necessary to protect from costly damage underground facilities used for producing, storing, conveying, transmitting, or distributing communication, electricity, gas, petroleum, petroleum products, hazardous liquids, water, steam, or sewage. In order to carry out this public policy and to satisfy these compelling interests, the General Assembly has enacted the provisions of this Article providing for a systematic, orderly, and uniform process to identify existing facilities in advance of any excavation or demolition in this State and to implement safe digging practices.
