Data extracted 15 November 2022

  1. 1 HVP means high vapour pressure as defined in Canadian Standards Association Standard Z662.
  2. 2 LVP means low vapour pressure as defined in Canadian Standards Association Standard Z662.
  3. 3 As of July 2014, the minimum reporting threshold for releases of low vapour pressure hydrocarbons was established at 1.5m³
