Overview

This page is intended to provide descriptions of each Electronic Positive Response (EPR) code and a set of example of when they should be used by members.  Following these best practices will not only ensure members are consistent as well as helping excavators understand what the member is communicating back to them.


While the best practice is a living document, it is important to remember that not every situation can be identified.  There will be cases where the member will have to use the best response available to them using all the information available at that time.

Response Code Definitions and Examples

001 : Clear - No conflict

Definition: The members lines are not in the area to be excavated.  This does NOT mean that the member doesn't have any line in the area.  A member may have lines near by, but based on the delineation and the location on the ticket, they are clear for that area.  If, for any reason the excavation area or type of work changes, the excavator MUST contact the notification center and get a new ticket issued for the changes.

When to use: ONLY when there are no underground facilities within the area of delineation and/or the location on the ticket.

002 : Clear - No conflict but privately owned utility on property - Contact private utility owner for locate

Definition: The members lines are not in the area to be excavated but the member knows there are privately owned facilities on the property.  This does NOT mean that the member doesn't have any line in the area.  A member may have lines near by, but based on the delineation and the location on the ticket, they are clear for that area.  If, for any reason, the excavation area or type of work changes, the excavator MUST contact the notification center and get a new ticket issued for the changes.

When to use: ONLY when there are no underground facilities within the area of delineation and/or the location on the ticket and there is knowledge of private lines in the area.

003 : Existing markings adequate

Definition: The markings on site are reasonably visible and marked to the extent of the delineation and/or ticket location.  If, for some reason the excavation area or type of work changes, the excavator MUST contact the notification center and get a new ticket issued for the changes.

When to use: When the existing markings on site are complete and accurate.

004 : No markings requested

Definition: The excavator is asking certain members or all members not to mark.  The most common use the centers see for this is on emergency work where the job was completed but the excavator needs a ticket number to make the permit valid. 

When to use: ONLY when the excavator is not asking for any marks.

010 : Locate area marked

Definition: The area of delineation and/or the ticket location area has been marked completely and accurately.

When to use: After the entire area of delineation and/or the ticket location area has been marked completely and accurately.

011 : Locate area marked but abandoned facilities may be in the area

Definition: Active lines are marked and the member has marked with an A in a circle to indicate the presence of known abandoned lines.  The marking of the A in a circle is to make the excavator aware that an abandoned line is in the area and is not subject to accurate marking.

When to use: If BOTH active and known abandoned lines are marked.

012 : Locate area marked up to private owned utility - Contact private utility owner for locate

Definition: The area of delineation and/or the ticket location area has been marked up to the ending point of what the member owns and maintains.  Lines downstream could be owned by the property owner or others and the excavator would need to get private locating done.

When to use: The member does NOT own or maintain the lines downstream 

013 : Locate area marked up to private property

Definition: The area of delineation and/or the ticket location area has been marked up to the ending point of what the member owns and maintains.  Member does not have easements on the private property.  Lines downstream could be owned by the property owner or others and the excavator would need to get private locating done.

When to use: ONLY when the member does NOT mark easements on private property.

014 : Partially marked - more time is needed

Definition: The area of delineation and/or the ticket location area has been partially marked.  Member needs more time to complete marking.

When to use: Member has been called away or needs more information to complete markings.  NOTE: this code does NOT close the ticket.

015 : Provided facility information to excavator (California Government Code 4216.3(a)(1)(A)(ii))

Definition: The member to the extent and degree of accuracy that the information is available, provides information to the excavator where the active or inactive lines are located.

When to use: Member does NOT locate and field mark their active or inactive lines but otherwise provides information to the excavator of where the lines are located.

020 : Bad address/incorrect street/location info - Resend ticket requested

Definition:  Member cannot find the location on the ticket.  Excavator will need to contact center to correct location.  Additional time may be needed to complete marking.  If mapping changes a new ticket will need to be issued.

When to use: Member cannot reach excavator by communication methods available on ticket to request the excavator to clarify or correct the location.

021 : No access to locate area - Resend ticket requested

When to use: The excavator has not delineated the area to be excavated.

023 : Delineated area does not match location requested - Resend ticket requested

Definition: There is a discrepancy between what is delineated on site and the description on the ticket.  This can cause confusion for the member locating the actual area the excavator will be working.  Excavator needs to clarify the location by sending an amendment on the ticket.  If mapping changes a new ticket will need to be issued.  Additional time may be needed to complete marking.

When to use: The member cannot determine where the actual excavation will be due to inconsistencies between site delineations and ticket location information.

030 : Contact facility owner for further info

Definition: The member needs the excavator to contact them to explain markings and/or processes needed to safe guard their lines while excavating.
