Low Impact Marking
Whether requesting a new locate ticket or renewing an existing ticket, excavators are required to follow low impact marking practices. This begins with the locate description on your ticket. The practices outlined below serve four purposes:
Helps ensure the locate is accurate
Reduces unnecessary locate marks
Reduces the amount of time locate marks are refreshed
Reduces time for the locator
Locate tickets should cover only those portions of a work site where digging will occur within 30 calendar days of the date the ticket is requested. Know the job site and give an accurate description of where it is located. Addresses, street intersections, railroad tracks, references to natural landmarks and driving directions are helpful.
When renewing tickets for jobs lasting longer than 30 calendar days, delete any areas where excavation is finished. Make sure that your office staff calls the field contact to confirm whether the locate ticket should be renewed and clarify what portion of the work site is incomplete. ***IMPORTANT*** If your office staff renews tickets, let them know when an ongoing project is complete so that tickets are not continually requested for that job.
Work sites that are difficult to describe should be pre-marked (white lined) if the excavator and member have not mutually agreed otherwise. See examples below.
Other helpful tips
Tell exactly where on the job site the digging will occur and how deep it will be.
Note any special conditions that may interfere with the locator doing his job such as a gated community, locked fences or a vicious dog.
If digging in one corner of an intersection, don't have the ticket cover an entire block. For example, you could specify that you're digging in the northeast corner or use a landmark to identify the corner.
Acceptable marking products for pre-marking a proposed excavation in white or marking underground facilities: flags, stakes, temporary/non-permanent paint, other industry accepted low-impact marking practices. Members are required to mark their underground facilities in appropriately designated colors.
