Reduction in the Release of Volatile Organic Compounds (Storage and Loading of Volatile Petroleum Liquids) Regulations — 1
cle tank being purged to a vapour control system or the vehicle tank being washed with a liquid that is not a volatile petroleum liquid. ( chargement en alternance ) tank means a tank, vessel, reservoir or container that is used to contain liquids, regardless of its shape or material of construction, but does not include (a) a vessel that operates under pressure or as part of a closed system such that there are no expected releases to the environment while the vessel is operating under normal operating conditions, including when it is being filled or emptied and when ambient conditions are changing; or (b) a cavern, underground porous rock reservoir or geological formation where liquids are stored under pressure. ( réservoir ) temporary vapour control system means a vapour recovery system or vapour destruction system designed for temporary or mobile use. ( système temporaire de contrôle des vapeurs ) vapour means any vapour or gas containing VOCs, including vapour arising from volatile petroleum liquid. ( vapeur ) vapour balancing system means a vapour control system that conveys vapours displaced during loading operations from the receiving tank to the source tank and prevents them from being released to the environment. ( système de retour en boucle des vapeurs ) vapour control system means a system that is designed to capture all vapours emitted from tanks or during loading operations and prevent them from being released to the environment. ( système de contrôle des vapeurs ) vapour destruction system means a vapour control system that destroys vapours by combustion, thermal oxidation or other means, including systems in which vapours are combusted to produce useful heat or energy and systems in which vapours are combusted for the sole purpose of preventing their release to the environment. ( système de destruction des vapeurs ) vapour leak means any release of vapour other than a release for which the concentration of VOCs at the source is determined, using a portable monitoring instrument, to be less than (a) 10 000 parts per million by volume, if the release is detected on or before December 31, 2026; or (b) 1000 parts per million by volume, if the release is detected after December 31, 2026. ( fuite de vapeur ) vapour pressure means the absolute partial pressure exerted on the walls of a vessel containing a liquid by the gas molecules above that liquid, when the liquid and its vapour are in equilibrium. ( pression de vapeur ) vapour recovery system means a vapour control system that captures vapours for a use other than their immediate use to produce heat or energy at a facility, including a non-regenerative system that retains the vapours in a solid or liquid medium. ( système de récupération des vapeurs ) vehicle means a machine that is designed to be mobile, including a truck, railcar, ship, transport barge or trailer but is not designed or has not been modified to serve for the purposes of the permanent stationary storage of liquids. ( véhicule ) vehicle tank means a tank attached to or integrated into a vehicle, other than a tank that is exclusively used to supply fuel to the vehicle’s engine. ( réservoir de véhicule ) vehicle-to-vehicle loading means the loading of volatile petroleum liquids directly from one vehicle tank to another without the use of a loading rack. ( chargement de véhicule à véhicule ) volatile organic compound or VOC means a compound that participates in atmospheric photochemical reactions that is not excluded under item 60 of Part 2 of Schedule 1 to the Act. ( composé organique volatil ou COV ) volatile petroleum liquid means petroleum, or a mixture that contains petroleum, that (a) exists as a liquid at a temperature of 20°C and an absolute pressure of 101.325 kPa; (b) contains 10% or more volatile organic compounds by weight; (c) has a vapour pressure greater than 10 kPa or, if the benzene concentration is greater than 2% by weight, 3.5 kPa; and (d) is not a mixture of petroleum and ethanol
