What is the Mississippi 811 (MS811) Positive Response Information System (PRIS)?

The MS811 Positive Response Information System (PRIS) is an automated information system operated and maintained by MS811. Mississippi Excavation Law requires that utility owners/operators report through PRIS the status of the work performed, within 3 working days. Excavators can review the information submitted to determine the status of their locate request prior to excavation. PRIS can increase excavation safety as well as improve communication between the utility and the excavator. It can also prevent delays in work and unnecessary “No Response” tickets.

Submitting Response Information:

Response information can only be submitted by member utility companies or their representatives. The following are the methods that the utility can use to submit positive response information.

MS811 Web Portal or Mobile App:

  • Response information can be submitted through the MS811 Web Portal or Mobile App.
  • A portal account with Positive Response (PR) permissions assigned is required when using this method. Click on the “Sign-Up” link above if you need to have an account set up.

Ticket Management System:

  • Most ticket management systems are set up to automatically send response information to the MS811 PRIS.
  • If your company is using a ticket management system and you are unsure if your response information is being transmitted to PRIS, contact the IT department for your ticket management system, or contact us at (601) 368-1150.
  • If you are not currently utilizing a ticket management system, but are interested in doing so, please keep in mind that a basic ticket management subscription for KorWeb is free for MS811 member utility companies.

Response Actions:

Located – Facilities marked

    • The utility has marked their facilities

Clear – No conflict

      • The utility does not have underground lines in the excavation area.
      • To prevent delays in work or possible infrastructure damage, utilities should always confirm that they do not have underground lines in the excavation area before submitting a “Clear” response.

On-Site Meeting Request – Utility is requesting to be on site during excavation

      • The utility operator may request to be present at the site upon commencement of the excavation, so long as the operator complies within 3 working days.
      • MS811 will not set up the meeting. The utility is required by law to contact the excavator directly to set up the meeting.
      • It is recommended that a callback # be added to the comments in case the excavator needs to reach the utility after initial contact.
    • Once the lines have been located, a “Located” response must be submitted to close the request.

Locate Delayed – Locate Delayed

      • This response action should be used when a utility can only locate its lines by excavation. A delay for any other reason is not in compliance with the law.
      • It is recommended that a reason for the delay and a callback # be added to the comments.

The following is a list of responses that are generated by the MS811 system:

  • Overdue – Utility did not submit a response by the required date/time
    • A response was not submitted by the date/time required by law and the utility is not in compliance with MS law.
    • A response must be submitted no later than 1 hour after the Locate By date/time on the locate request ticket or the MS811 system will automatically post an “Overdue” response.
  • No Response – Utility did not submit a response before the ticket expiration
    • A response was not submitted before the expiration of the ticket and the utility is not in compliance with MS law.
    • If a response is not submitted before the Expires date/time on the locate request ticket the MS811 system will automatically post a “No Response” status within the hour following the expiration of the ticket.
  • Non-Participant – Company is not currently participating in Positive Response
    • The utility is not currently participating in the Positive Response program and is not in compliance with MS law.
    • MS law requires that all utility companies submit response information to the MS811 Positive Response Information System.
    • The MS811 system will automatically post a “Non-Participant” response soon as a ticket is created for non-participating utilities.
