FAQ

  • Will the utility companies let me know when the lines are marked?

    You can view up-to-date responses from all utility companies notified by Tennessee 811 by checking Positive Response via the Ticket Search.


    Positive Response is a service that TN811 provides to help you track the status of your locate request. 


    In accordance with the Underground Utility Damage Prevention Act (65-31-108 (b)), all member utilities are required to notify Tennessee 811 that they have marked the approximate location of underground facilities or that the member has no underground facilities in the proposed area of excavation via Positive Response. 

  • How soon can I dig once the locate request has been placed?

    1) When all utilities listed on your ticket have responded to Positive Response.

    2) Your legal start date and time has been reached.


    If you are missing responses in Positive Response or observe clear evidence of unmarked utilities, you are required to call 811 to submit a 2nd Notice. The 2nd Notice allows 811 to notify the utilities of the issue. There is no additional wait time required after you submit a second notice, but we suggest you wait until all lines are marked to begin your digging work.


    It is very important to wait until the legal start date and time assigned. Beginning work earlier can result in forfeiture of your rights and protections granted under the Tennessee code, 65-31-101.
