About 415 000 kilometres of Canada’s oil and gas pipelines operate solely within Alberta’s boundaries and fall under the jurisdiction of the AER. Certain rate-regulated gas transmission pipelines fall under the jurisdiction of the Alberta Utilities Commission, for which the AER conducts field inspections and provides incident response. Oil and gas pipelines that cross provincial or federal borders are regulated by the National Energy Board. 

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 pipeline fluid characteristics, location, line size, failure history, and the company’s compliance history. Pipelines with greater potential risks are given a higher inspection priority.

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.

Report 2013-B: Pipeline Performance in Alberta, 1990–2012 is a comprehensive analysis of pipeline data for Alberta on amounts and types, incident statistics, and incident rates.

Please see the Pipeline Safety Review webpage for the report, video, feedback, as well as organizational responses.

Compliance Assurance
Manual 005: Pipeline Inspections identifies noncompliance events. Noncompliance with the requirements may result in the licensee of the pipeline or duty holder receiving a response from the AER in accordance with the processes described in Directive 019: Compliance Assurance.

The Compliance Dashboard demonstrates how the AER is involved in incident response, investigations, compliance, and enforcement. The AER also publishes a number of educational resources—presentations, FAQs, brochures, and guidance information—that relate to AER directives, rules, and regulations.
