The AER ensures that the design, construction, operation, and maintenance - including discontinuation and abandonment of regulated pipelines - complies with Alberta’s Pipeline Act, Pipeline Regulation, and applicable Canadian Standards Association (CSA) standards.

The AER's pipeline-inspection program considers potential risks of individual pipelines and pipeline fluid characteristics, location, line size, failure history, and the operator’s compliance history. Pipelines with greater potential risks—such as those that transport sour gas, are near water bodies, or belong to a licensee with poor compliance history—receive greater scrutiny.

The AER also conducts comprehensive incident investigations after serious incidents occur to determine the cause of a pipeline failure and what can be done to prevent a similar situation in the future. Any enforcement action the AER takes is made public on our compliance dashboard, and may include enforcement orders, shutting down operations, administrative penalties, and prosecution.

  • Compliance Dashboard shows how the AER is involved in incident response, investigations, compliance, and enforcement.

  • Pipeline Performance Our goal is to reduce the number of high-consequence pipeline incidents by two per cent in 2017, compared to the previous two-year average.
  • Pipeline Safety The AER regulates more than 422 000 kilometres of oil and gas pipelines and provides inspection and incident response support for an additional 12 000 kilometres of pipelines regulated by the Alberta Utilities Commission. The majority of the pipelines that the AER is responsible for are smaller lines that connect individual wells to gathering facilities for treatment or processing, which then connect to larger-diameter lines.
