One-Call Legislation

Legislative Software Enhancements – For Colorado 811 Members

The Colorado Legislature passed new legislation which affects our industries in many ways. The Legislature wants to improve excavation safety to protect critical utility assets and save lives.

The 2018 changes in the law will now require all of us to do business differently; excavators, facility owners, locate services and your utility notification center Colorado 811. Colorado 811 is working extremely hard to implement the changes in the law that directly affect Colorado 811 and the changes rely in part on new software.

In 2018, Colorado 811 communicated to the membership some upcoming software changes driven by the new law. We are diligently working to complete the development and testing of software enhancements that will allow us to process new ticket types and provide our stakeholders a higher level of service and meet legislated mandates. Development also continues for delivery of notifications to our Tier Two Members as required by the new legislation. We understand the urgency to complete these mandates while ensuring accurate and timely notifications to all our members.

As we deliver the software enhancements we want to assure our members that we intend to ‘get it right the first time’. We understand our members’ expectations to develop, test and deploy software enhancements timely and in a way that will not adversely affect their ability to serve the excavating community.

Our first new software deployment will begin on January 28, 2019, and will include the following: new ticket delivery format, Tier Two ticket deliveries and new positive response codes.

Colorado 811 has been working bi-weekly with the State of Colorado Division of Oil & Public Safety (OPS) throughout the transition period with both entities sharing progress updates. The new Safety Commission has been established and the Safety Commission and CO811 will be communicating with stakeholders in unison. We are providing numerous educational opportunities including seminars, website postings and media interviews. We have received positive feedback on our efforts as we continue with our deployment of new services and a joint public awareness campaign.

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.

Subsurface Utility Engineering Request

A Subsurface Utility Engineering (SUE) Request is processed when the project is designed by a licensed professional engineer and the project will include the investigation and depiction of existing underground facilities that meet or exceed the ASCE 38 standard.

A SUE required project means a project that meets ALL of the following conditions:

  • The project involves a construction contract with a public entity.
  • The project involves primarily horizontal construction and does not involve primarily the construction of buildings.
  • The project has an anticipated excavation footprint that exceeds two feet in depth and is a contiguous one thousand feet or involves utility boring.

Recommended Facility Owner Response:

Facility owners/operators must respond within ten business days with one of the following:

  • Provide underground facility location records that give the available information on the location
  • Provide marks on the ground that give the approximate location
  • Provide available information as to the approximate location

*Not to include depth for all of the above*

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.
