Foreword

This document is a summary of selected 2015 pipeline safety data. It covers federally regulated pipelines only. Data concerning non-federally regulated pipelines reported to the TSB are not included in this report.

The TSB gathers and uses this data during the course of its investigations to analyse safety deficiencies and identify risks in the Canadian transportation system.

The 2015 data were collected according to the reporting requirements described in the TSB Regulations in force during that calendar year.

The statistics presented here reflect the TSB database at 17 February 2016. Since the occurrence data are constantly being updated in the live database, the statistics may change slightly over time.

Because many occurrences are not formally investigated, information recorded on some occurrences may not have been verified. Consequently, be cautious in using these statistics.

The following data tables are associated with the Statistical Summary – Pipeline Occurrences 2015.

Federally regulated pipeline occurrences.
In 2009, there was a 38% increase in the size of the federally regulated pipeline system when an additional 23 705 kilometres of pipeline and associated facilities were transferred from provincial jurisdiction.
*New TSB regulations came into effect on July 1, 2014. Under the new reporting requirements the minimum reporting threshold for incidents with release has been changed to be the same as NEB regulations which is 1.5 m³ of low vapour pressure hydrocarbons.
