In Alberta, pipelines are regulated by the Energy Resources and Conservation Board (ERCB). The ERCB has established a controlled area for pipelines in the province. A pipeline’s controlled area is the land bordering it for 30 metres (100 feet) along each side, measured from the centre of the pipeline.

If you are planning any ground disturbance activities within 30 metres (100 feet) of the pipeline, you must contact Alberta One-Call at (800) 242-3447 at least three working days prior to any work being started. Any ground disturbance within 30 metres of pipeline must be supervised by trained Enbridge staff who can safely direct the activity.
