Data extracted July 16, 2018 ¹ HVP means high vapour pressure as defined in Canadian Standards Association Standard Z662. ² LVP means low vapour pressure as defined in Canadian Standards Association Standard Z662. ³ As of July 2014, the minimum reporting threshold for releases of low vapour pressure hydrocarbons was established at 1.5m³.
