Positive Response is required by Colorado State law, to be provided by the underground facility owner to the excavator requesting the locate request. The facility owner is required to post Positive Response through the Colorado 811 Positive Response system. If the Tier One facility owner has not posted in the Colorado 811 system within the required time-frame, a re-notification must be submitted. Please note that Tier Two members cannot post a response into Positive Response until they have fully converted to Tier One membership.
Colorado811 agents do not have a direct link to provide positive response information for any locate request. please refer to this program only through www.colorado811.org, or call the facility owner directly.
PLEASE DO NOT MAKE CALLS TO 8-1-1 FOR POSITIVE RESPONSE INFORMATION
