NOTE:  These observed holidays will NOT be included when calculating the "three full working days" wait period for having your lines located.

Tennessee 811 will, however, be open 24 hours a day, 365 days per year, including holidays for all ticket locate requests.

This means you can call in, or enter, a locate ticket 24/7, 365 days a year, but the 72 hour waiting period before digging, will be increase by one day if a 72 hour wait period includes a holiday within that time frame.
