Call 811 Before You Dig

Avoid Careless Damage and Accidents

Oklahoma law requires utilities and line owners to register their underground facilities in every county - and for excavators to contact every potentially affected operator before they start to dig. Excavators include fence builders, swimming pool contractors, and landscapers. Homeowners who do this type of work themselves may also be considered excavators. Anyone digging in the vicinity of a pipeline should use the free statewide system at Oklahoma One-Call to be sure they know where they can safely dig.

Call Okie: The Oklahoma One-Call System
The Oklahoma One-Call System is a statewide organization that makes locating lines easy. They operate a computerized notification center that establishes an important link between excavators and underground line operators like Oklahoma Natural Gas.

Here’s how this free service works. Excavators (including homeowners) should Call Okie at 811 or 1-800-522-6543, or access their web site at at least full two business days before digging starts. (Calls received with less than two business days notice are considered non-compliant requests under state law.) In less than five minutes, the excavator can complete a locate request ticket to have all utilities located with paint and/or flags at the proposed dig site. A full explanation of state laws and instructions for web-based ticket requests is available on the web site.

A "locate request call" sets the following process in motion:

  1. Operators with underground facilities in the vicinity of the planned excavation are notified by Oklahoma One-Call. This includes natural gas and power utilities, communications companies, and cities and towns.
  2. Operator crews or their subcontractors either mark their underground facilities or tell the excavator they have no lines in the area.
  3. Excavators or homeowners can recognize the type of line marking on a site by using the following color code:
    Red = Electric
    Yellow = Gas, oil or steam
    Orange = Telephone or television
    Blue = Water
    Green = Sewer
    Pink = Temporary survey markings
    White = Proposed excavation

Pipeline Safety Considerations

  • When planning your landscaping projects, avoid planting trees or large shrubs near your gas meter. As the tree grows, it can exert forces on your meter setting which could result in damage to the gas pipeline facilites.
  • You can help enforce safety laws, by shutting down any contractors you are using who do not use the One-Call system. For example, if your fence or pool contractor starts digging before you see any paint or flags in your yard, you will know he probably is not complying with the One-Call law. By shutting down the excavation work, you will be protecting your own property by preventing damage to gas, electric, water, and communication facilities.
