( programme de surveillance du périmètre ) fixed roof means a roof that is permanently attached to a tank. ( toit fixe ) fixed roof tank means a tank that is equipped with a fixed roof but is not equipped with an internal floating roof. ( réservoir à toit fixe ) flare means any type of combustion device without an enclosed combustion chamber, including a burn pit designed to burn liquids or mixtures of gases and liquids. ( torchère ) floating roof means a structure that floats on the surface of a liquid and whose purpose is to limit vapour loss of that liquid to the environment. ( toit flottant ) gasoline means (a) a fuel that is sold or represented as gasoline with a benzene concentration of less than or equal to 1.5% by volume; or (b) a petroleum distillate, or a mixture of petroleum distillates, oxygenates or additives, that is suitable for use in a spark ignition engine and has the following characteristics, as determined using the applicable test method listed in the National Standard of Canada standard CAN/CGSB-3.5-2021 entitled Automotive gasoline : (i) a vapour pressure of at least 35 kPa, (ii) an antiknock index of at least 80, (iii) a distillation temperature at which 10% of the fuel has evaporated of not less than 35°C and not greater than 70°C, (iv) a distillation temperature at which 50% of the fuel has evaporated of not less than 60°C and not greater than 120°C, and (v) a benzene concentration of less than or equal to 1.5% by volume. ( essence ) guide pole means a structure that is placed in a tank equipped with a floating roof for the purpose of preventing the floating roof from rotating within the tank or for the purpose of monitoring or sampling the liquid inside the tank. ( poteau de guidage ) high benzene loading rack means a loading rack that is designated under paragraph 13 (a) or used to load a volatile petroleum liquid with a benzene concentration greater than 20% by weight. ( rampe de chargement de liquide à haute concentration en benzène ) high benzene tank means a tank that is designated under paragraph 12 (a) or contains a volatile petroleum liquid with a benzene concentration greater than 20% by weight. ( réservoir de liquide à haute concentration en benzène ) inerted tank means a tank that opens to the atmosphere only through a pressure-vacuum vent and that is supplied with a non-hydrocarbon inert gas such that the atmosphere inside the tank contains insufficient oxygen to support combustion. ( réservoir inerté ) internal floating roof means a floating roof that is installed in a tank with a fixed roof such that the upper surface of the floating roof is protected from atmospheric conditions. ( toit flottant interne ) liquid means any type of liquid, including volatile petroleum liquid. ( liquide ) liquid leak means a leak for which three drops of liquid per minute or more form at the source as measured from the average number of drops per minute observed visually over a period of three minutes. ( fuite de liquide ) loading means any transfer of a liquid into a vehicle tank or from a vehicle tank into a fixed roof tank. ( chargement ) loading factor means a numerical value that represents the level of VOC emissions from a loading rack. ( facteur de chargement ) loading rack means all of the stationary equipment used for loading liquids, including structures, loading arms, pumps, piping and instrumentation. ( rampe de chargement ) lower explosive limit or LEL means the lowest concentration of a combustible vapour in the air that may ignite at a given temperature and pressure. ( limite inférieure d’explosivité ou LIE ) lower explosive limit percentage or LEL% means the ratio of the observed concentration of a combustible vapour to the LEL of that vapour, expressed as a percentage. ( pourcentage de la limite inférieure d’explosivité ou pourcentage LIE ) occupied building means a structure located
