One-Call Legislation

Legislative Mandates for 2019

Colorado 811 is currently working with the State Safety Commission as we develop stakeholder educational training and software enhancements to accommodate the many mandates of C.R.S. We expect to accommodate these new types of requests related to the new legislation before the beginning of Dig Season 2019.

Please visit our website regularly and follow our social media sites (Facebook and Twitter) as we strive to accommodate the provisions under the new law.

Questions or concerns can be directed to Director of Damage Prevention, Marty Mead, [email protected].

Thank you,

Colorado 811

Secondary Excavator


Starting January 1, 2019 a secondary excavator may be added to the locate tickets for potholing or exposing utilities only. When a secondary excavator is listed by the primary excavator on a locate ticket the secondary excavators contact info will be listed in the fields called “Potholing Company”.

If the primary excavator on the ticket decides to add a secondary excavator for potholing, this information must be added when the ticket is originally created. A secondary excavator cannot be added to the ticket after the ticket is created. 

Recommended facility owner response: The response does not change, post a positive response before the locate-by-date using the Colorado 811 Positive Response system.

Please note: It is the primary excavator’s responsibility to communicate the positive response to the secondary excavator.

Road Grading Request

A Road Grading Request is only for annual road maintenance conducted by a governmental agency on an existing unpaved road that does not exceed six inches in depth (grading to be performed between shoulders of road only).

A Road Grading ticket does not include any work performed in ditches (i.e. fore slope, flow line, back slope; not to exceed six inches in depth). The markings shall be considered valid for up to one hundred and eighty days.

Road Grading Ticket Process:

  • It is the county’s responsibility to create a Road Grading ticket ten days prior to the commencement of all grading activities being performed within county limits.
  • When a Road Grading ticket is generated a countywide notification for all roads within a county that need to be graded is sent out to area utility providers.
  • If needed locates have not been completed by a utility provider within ten days of receiving the Road Grading ticket, a grading excavator will contact the ticket notification center for an excavator re-notification. This secondary notification will be only for the utility providers who failed to respond to the initial notice only. After the utility re-notification has been performed the road grading may proceed.
  • While performing grading activities, the operator must follow all laws in regards to excavating within a tolerance zone.

Recommended Facility Owner Response:

  • Upon receipt of the notification, an owner or operator has ten business days to coordinate the excavation activity with the governmental agency.
  • Utility providers will ensure facilities that are in conflict are properly marked with paint, “whiskers”, or permanent marker on the public right of way delineating the path of facility utility lines.
  • If a facility owner chooses to place permanent markers in the public right of way, documentation of conflicts found should be sent as an email attachment in response to the Road Grading ticket.

Mandatory Positive Response

Due to legislative changes to the Colorado One Call law posting Positive Responses to locate ticket notifications through Colorado 811 will be mandatory starting January 1, 2019. Along with posting Positive Responses a facility owner/operator will be able to provide the excavator with documentation like additional comments, sketches, pictures and/or maps through Colorado 811 beginning in 2019. Positive Responses must be received by Colorado 811 before the legal locate by date on the locate ticket notification. Colorado 811 offers four different methods to post Positive Responses and meet this requirement.

How do I get started with posting positive responses?

There are four methods available to post Positive Response, they include:

  • Positive Response Website (username and password are required)
  • Colorado 811’s Positive Response 800 number
  • Vendor run Ticket Management System  (username and password are required)
  • WebTMS (provided by Colorado 811)

Please contact Member Services at [email protected] for more information or to get started.

What happens if your company does not post a Positive Response to Colorado 811 by the locate by date?

If Positive Response is not provided to Colorado 811 by the locate by date, Colorado 811 will send an additional Positive Response re-notification to that facility owner/operator. Colorado 811 will continue to send out re-notifications daily until Colorado 811 receives Positive Response from the facility owner/operator. These re-notifications will be charged to the member at the standard ticket transmission fee.
