Requirement to Provide Electronic Positive Response (EPR)

Underground Safety Board

As of January 1, 2021 California law (Government Code 4216.3(c)(1)(A)) requires that every operator of a subsurface installation, not granted an extension pursuant to 19 CCR 4020 make an electronic positive response (EPR) to each applicable excavation location request ticket through the appropriate regional notification center before the legal excavation start date. From July 1 to October 1, 2020 the California Underground Facilities Safe Excavation Board provided an opportunity for operators to apply for extensions to this requirement. Applications are no longer being accepted.

Pursuant to Government Code 4216.3 and implementing regulation 19 CCR 4020 the California Underground Facilities Safe Excavation Board extended the deadline to provide electronic positive responses to December 31, 2021 for the following operators:

What is Electronic Positive Response (EPR)?

An EPR is a standardized code that notifies a contractor/excavator that you (the facility owner or operator) have responded to the ticket and the manner in which you have responded, such as whether the ticket area is clear of your facilities, you have completed the locate and marking of your facilities, or you ran into an issue or emergency in responding to the ticket.
