Download our Positive Response PDF (below) for an overview of all the changes.
One new positive response code will be introduced for facility owner/operator members to use when posting to tickets:
- 025 - Locate Not Completed
-
- Will not require an attachment, code will require comments in field. We will renotify until a complete response is received. If agreement to locate later/time is subsequently reached with excavator during the life of ticket, code 023 must be used and an attachment with agreement must be provided to stop renotifications. If subsequent EXRN is filled, renotifications will resume until the end of the ticket or respectively.
- The addition of this code is designed to foster clearer communication between utility owners and excavators, ensuring everyone involved has an accurate understanding of ticket status, especially when work is pending or additional verification is needed.
OTHER CHANGES TO POSITIVE RESPONSE PROCEDURES & CODES
Modified Positive Response Codes
Clearer descriptions on Positive Response Codes : The following response codes are modified to clarify communication between facility owner/operator members and excavators.
- 011 - Completed - See Documentation and/or Marks on Site; Abandoned Facilities May be in the Area
- 019 - Marked, All Crossings Must Be Exposed During Trenchless Excavation in order to observe a safe crossing
Removed Positive Response Codes
Colorado 811 will remove three (3) positive response codes from the responses available.
- 008 – Call Facility Owner for Further Info on Locate
- 015 - No Locate Due To Extreme Weather/Emergency Conditions in Area of Locate
- 020 – Sewer Marked – Best Available Info Provided on Laterals
The removal of these response codes supports Colorado 811’s goal to improve clarity, efficiency, and accountability in the ticket response process. Members are encouraged to use the more descriptive response codes and provide complete responses, including all required documentation and file attachments, to ensure clearer communication and resolution of locate tickets.
The following response codes will require comments
- 021 Existing Marks Verified
- 022 No Locate Necessary – Per Excavator No Locate Needed
- 025 Locate Not Yet Started
Starting on the evening of January 29, 2026, Colorado 811 will require Facility Owner/Operator Members to upload supporting documentation like photos, maps, or sketches as part of their Positive Response. If a response is not posted, incomplete, or supporting documentation is not provided by the due date, the system will automatically send Positive Response Renotifications daily for up to 30 days, or until a positive response code and required documentation is uploaded—whichever comes first. Please note, a Positive Response will not be complete unless a file attachment is submitted.
- Renotifications are sent if there's no attachment, except for responses:
- 002-Clear No Conflict
- 013-No Conflict (Privately Owned Utility—contact owner for locate)
- 025-Locate Not Yet Started
- Renotifications are also sent if there's no attachment, except for these ticket types:
- Damage
- Emergency (no renotifications due to no response or attachment)
