Call 811 Before You Dig — It’s the Law!

Even relatively minor excavation activities, like landscaping or fencing, can damage a pipeline. In fact, most pipeline accidents that lead to injuries and serious damage occur when a third party works within a pipeline or utility right-of-way. To help prevent accidents, the law requires you to contact your state One-Call Center before you dig. Call 811. It’s free!

Call 811 at least three days before doing any of the following:

  • Blasting
  • Construction
  • Digging
  • Drilling
  • Excavating
  • Farming
  • Fencing
  • Landscaping

What to expect when you call

Most states, including Pennsylvania and New Jersey, require that you call the One-Call Center at least three days in advance of any digging, fencing, etc. This allows operators to mark their pipelines and utilities at your proposed digging site. In addition, MIPC may require a company representative to authorize and be present for any excavation within our pipeline right-of-way.

What to look for before diggingPipeline Line Markers Graphic

Most pipelines are underground, and burial depth varies. Whether the pipeline is buried or above ground, the pipeline right-of-way is clearly identified by pipeline markers along the route. These markers identify the approximate — NOT EXACT — location of the pipeline. The marker shows MIPC company information, type of product transported and emergency contact information.

What is a right-of-way and can I build or dig on it?

MIPC maintains written agreements with landowners that allow for ease of access and maintenance when we cross private property. These agreements, also called rights-of-way, are often recognizable as corridors that are clear of trees, buildings or other structures except for the pipeline markers. A right-of-way may not have markers clearly present and may only be indicated by cleared corridors of land, except where farm land or crops exist. County Clerk or Recorder of Deeds offices may also have records of these agreements.

Encroachments upon the pipeline right-of-way inhibit MIPC’s ability to reduce the chance of third-party damage, provide right-of-way surveillance and perform routine maintenance and required federal/state inspections. In order to perform these critical activities, MIPC maintenance personnel must be able to easily and safely access the pipeline right-of-way, as well as areas on either side of the pipeline. Keeping trees, shrubs, buildings, fences, structures and any other encroachments well away from the pipeline ensures that the pipeline’s integrity and safety are maintained.

For questions concerning the pipeline, right-of-way or future property improvements or excavations, contact MIPC at (610) 485-3709.
