Call Tennessee One Call at 800-351-1111 and/or contact the Engineering Department's Office for more information.
One of the most important functions of the Engineering Department is the administration of the Tennessee One Call (TNOC) program. The Tennessee One Call System, Inc. (TOC) is a computerized information center located in Nashville which establishes a communication link between excavators and those who operate underground facilities (operators) in Tennessee. The Tennessee Code requires anyone who engages in, or is responsible for, the planning or performance of any type of excavation to provide at least three working days advance notice and not more than ten working days notice to underground facility owners who may be affected by the excavation.
