Underground Utility Damage Prevention
Underground Utility Damage Prevention Act
The purpose of the Underground Utility Damage Prevention Act is to prevent harm to people, property, and underground utility facilities. The provisions of the Act are codified in Tenn. Code Ann. § 65-31-101 et al. The Tennessee Regulatory Authority’s role is to assist the Underground Utility Damage Enforcement Board by providing administrative and investigative support.
Excavation or Demolition Projects
When planning an excavation/demolition project, contact Tennessee 811 to have underground utility lines marked before the project begins. Marking utility lines helps prevent injury to people as well as damage to property and infrastructure. There is no charge for requesting utility markings. Tennessee811 may be reached by dialing 811 or via the web at www.tennessee811.com/.
Before You Excavate or Demolish
- Mark the proposed excavation site in white; such as white flags, paint, or stakes.
- Contact Tennessee 811 by dialing 811 or visiting www.tennessee811.com/ to submit an electronic locate ticket. There is no charge for requesting utility markings.
- Tennessee811 will notify utility companies that service the excavation/demolition area. Utility companies have three (3) business days to mark the site. You will need to wait three (3) business days before excavating/demolishing. If after three (3) business days, there is no clear evidence of the presence of an unmarked utility; you may proceed, always using care not to damage underground facilities.
- If after three (3) business days, one or more operator has failed to mark their facilities and there is clear evidence of the presence of an unmarked utility, you must contact Tennessee811 with a second request. You may begin excavating/demolishing after notifying Tennessee811 of the unmarked utility, always using care not to damage underground facilities.
