Data extracted June 15, 2017.
All five-year averages have been rounded. Totals sometimes do not coincide to the sum of averages.

New TSB regulations came into effect on July 1, 2014, changing some reporting requirements.
* Under 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 cubic metres of low vapour pressure liquid hydrocarbons.
