Pipelines are installed in a right-of-way or an easement through property. It is vital for the safe operation [of the pipeline] that the company has access to the pipeline free of obstructions. Access is needed for required maintenance and surveillance. Landowners and tenants have an obligation not to place buildings, fences, trees, shrubs or other obstructions on the pipeline right-of-way. Contact the pipeline company if you have questions or if you are planning improvements to your property near a pipeline.
Because pipelines are buried underground, markers are used to indicate their approximate locations along the route. The markers display the material transported in the line, the name of the pipeline operator, and a telephone number where the operator can be reached in the event of an emergency.
Pipeline leaks can be recognized using three of the five senses: sight, sound, and smell. If you suspect a leak, most importantly, turn off any equipment and leave the area as quickly as possible.
