3.29 One Call Facility Locate Request Size and Scope

One Call Center

Practice Statement: 

A maximum locate request area that is appropriate for a proposed excavation site is defined for a facility locate request.54

Practice Description:

Designating a manageable locate request size (work area size/scope) along with clear locate instructions will reduce uncertainty and provide clarity to the utility operators and/or locators as to "what" and "where" needs to be located and marked. This is designed to prevent unnecessary locator effort and allow adequate time to locate and mark the affected underground facilities within the time frame and marking requirement of the appropriate state statute.


  • Existing state laws, including Georgia, Indiana, Pennsylvania, and South Carolina (as examples)
