(1) Annual throughput. The amount of gasoline transferred into or dispensed from a gasoline dispensing site during any 12 consecutive months.

(2) CARB. California Air Resources Board as defined in California’s Health and Safety Code, section 39003 (1975) (see Table 1, section 200.9 of this Title).

(3) Dual-point vapor recovery system. A gasoline storage tank equipped with an entry port for gasoline and a separate exit port for vapor collection.

(4) Gasoline. A petroleum distillate or petroleum distillate/alcohol blend having a Reid vapor pressure of 27.6 kilopascals or greater, which is used as a fuel for internal combustion engines.

(5) Gasoline dispensing site. A site where gasoline is dispensed into motor vehicle fuel tanks or into portable containers from a stationary gasoline storage tank larger than 250 gallons.

(6) Gasoline storage tank. A stationary storage tank larger than 250 gallons located at a gasoline dispensing site which is used to store gasoline.

(7) Gasoline transport vehicle. A tank truck, trailer or railroad tank car, with a capacity of 300 gallons or more, used to transport gasoline.

(8) Gauge well. An opening in the top of a gasoline storage tank used to measure the amount of product in the tank.

(9) Reconstructed. Any physical change to a gasoline storage tank where the fixed capital cost of the new components exceeds 50 percent of the fixed capital cost that would be required to construct a comparable new source.

(10) Stage I vapor recovery system. A system that forces gasoline vapors from a gasoline storage tank into a vapor-tight gasoline transport vehicle through direct displacement of the gasoline being transferred.

(11) Stage II vapor recovery system. A system that captures gasoline vapors displaced or withdrawn from a vehicle fuel tank during refueling and returns the vapors back to the gasoline storage tank.

(12) Submerged filling. The use of a fill pipe or drop tube intended to minimize splashing of gasoline when loading a gasoline storage tank.

(13) Vapor-tight. A condition that precludes vapor loss. Compliance with vapor-tight requirements can be determined by checking to ensure that the concentration at a potential leak source is less than 100 percent of the lower explosive limit (LEL) when measured with a combustible gas detector, calibrated with propane, at a distance of 1 inch from the source.

(14) Vehicle dismantling facility. A facility that decommissions, dismantles and recycles end of life vehicles.
