The transport of hydrocarbons is a heavily-regulated industry throughout Canada and the world. Trans Mountain is committed to comply with all applicable regulations.
The National Energy Board, Onshore Pipeline Regulations, 1999, and the Canadian Standards Association Z662, Oil and Gas Pipeline Systems code, ensure that pipelines are designed and operated to prescriptive requirements. These requirements include design, quality of materials, construction, and operations and maintenance.
