The National Energy Board (NEB) in past years has developed a number of Safety Advisories. The Advisories were often developed as a result of the NEB's investigation into pipeline incidents that occurred on federally regulated Canadian pipelines. The advisories contain important information related to safety matters. As well, the Transportation Safety Board of Canada (TSB), who also investigates incidents on federally regulated Canadian pipelines, has developed Safety Advisories that have been received by the NEB. The NEB is of the view that it is imperative that the information contained in these Advisories be shared with all interested parties. Therefore, the Advisories are now being placed on the NEB's Web site in the Safety & Environment section for public viewing. Should the need arise in the future for safety advisories to be created related to environmental issues, such advisories will also be placed on this Web site.
