Call Before You Dig

Even though underground pipelines are identified with pipeline markers, one cause of pipeline leaks is damage caused by earth-moving and construction equipment and tools owned by parties other than the pipeline company.

  • If you plan to dig or do any type of excavation or construction work, call 811 from anywhere in the country a few days prior to digging. Your call will be routed to your local One Call Center.
  • Tell the operator where you're planning to dig and what type of work you will be doing. Your affected local utility companies will be notified about your intent to dig. Every digging job requires a call, even small projects like planting trees and shrubs. The depth of utility lines varies and there may be multiple lines in a common area. Digging without calling 811 can disrupt service to an entire neighborhood, harm you and those around you, and potentially result in fines and repair costs.
  • Within a few days after an 811 call, a locator will be dispatched at no cost to you to mark the approximate location of your underground lines, pipes and cables, so you'll know what's below—and be able to dig safely.

Calling 811 before every digging job gets your underground pipelines and utility lines marked for free, and helps prevent hazardous consequences.

When contacting 811, provide the One Call Center with the:

  • Project location and address
  • Project description
  • Project duration
  • Special instructions helpful for marking the site

You should always wait the required time to allow utility and pipeline representatives to mark the location of lines in the area. In addition, the One Call Center will provide you with a locate request number and a list of companies that will be notified. Keep this information with you on the project site.

Excavation and One Call requirements differ from state to state. Check with your state prior to beginning any project. For additional information about your state’s One Call requirements, visit For more information about 811 and the "Call Before You Dig" process, go to

Preventing ROW Encroachment

A pipeline right of way (ROW) or easement is a strip of land over and around a pipeline.

Pipeline ROWs and easements are permanent, limited interests in the land that enable the pipeline company to operate, test, inspect, repair, maintain, replace and protect one or more pipelines on the landowner's property. Generally, the pipeline company’s ROW include the land above and approximately 25 feet on either side of the pipeline, though easement agreements can vary.

For the safe operation of the pipeline, restrictions typically prohibit building, planting or storing items in the ROW. In some cases, farmers or ranchers may retain surface rights above the pipeline for agricultural purposes. Unauthorized building or planting in the pipeline ROW is known as encroachment.

We work with landowners to help educate them and to avoid encroachment on our pipeline ROW. Located on a Plains ROW? Click the following links to view the following Plains Landowner Guides:
