Electronic Positive Response (+Response or EPR) is communication from the utility member (contract locator) to the excavator regarding the status of a DigAlert ticket. California has always had +Response in the law by requiring members to notify the excavator with status or mark the area to be excavated on site. What changed in Government Code 4216 on January 1st, 2017, is that Electronic Positive Response can now be made through the Notification Center starting January 1st, 2018. However, DigAlert began offering this service starting November 1st, 2017. During 2018, 2019 & 2020 EPR was voluntary but starting on January 1st, 2021 EPR became mandatory for members, unless a 1 year extension was given prior by the Underground Safe Excavation Board. Then on January 1st, 2022, EPR became mandatory for all members.
This means that members must respond to DigAlert's servers about the marking status of the ticket. DigAlert will then allow the excavator to check the responses through the website, SMS and apps anytime during life of the ticket. In addition, DigAlert will email the excavator at the start date and time listed on the ticket a complete status of responses, if the excavator has supplied an email address on the ticket and given permission to send emails.
How it Works.
Once a ticket is created, it is sent out to all utility members who asked for notification in that area. As members clear or respond to the site they send a response back to DigAlert with information about what was completed. For example; "locate area marked", "no access to area", "clear - no conflict", etc. DigAlert will store that information with the ticket along with a date & time stamp. Members can make multiple responses to the same ticket however responses can't be edited or deleted. This means that all responses will show with their corresponding date and time.
To use Electronic Positive Response as a utility member (or contract locator) you must;
Be a member in good standing of DigAlert (for contract locators, the company you are locating for must be a member in good standing)
Be assigned at least one active member code (done at the time of joining)
Notify DigAlert you wish to use EPR through the center by calling the administration office at (951) 808-8100
Decide how you will submit your responses to DigAlert from one of the 4 above methods
If you have multiple facilities (water, electric, sewer) and you only have ONE member code, when you respond you CANNOT respond differently per facility. There can be only one response PER member code. This is why we recommend one code per facility type
DigAlert recommends that if you have multiple facility types (water, electric, sewer, etc) that you have a member code for each type.

Benefits of Using EPR
For the member, EPR is an effective means of reducing the number of retransmits that they receive because the excavator saw no markings at the dig site.
For excavators, EPR provides them with information about the member facilities prior to arriving on the job site. If they provided an email address when the locate request was called in they will receive an email confirmation after the start date & time listed on the ticket.
