Gasoline Vapors from Gasoline Transfer and Dispensing Operations: Definitions
(1)“Equivalent control” means the use of alternate operational and/or equipment controls for the reduction of gasoline vapor emissions, that have been approved by DEQ, such that the aggregate emissions of gasoline vapor from the facility do not exceed those from the application of defined reasonably available control technology.
(2)“Gasoline” means any petroleum distillate having a Reid vapor pressure of four pounds per square inch (28 kilopascals) or higher, used as a motor fuel.
(3)“Gasoline dispensing facility” means any site where gasoline is dispensed to motor vehicle, boat, or airplane gasoline tanks from stationary storage tanks.
(4)“Annual throughput” means the amount of gasoline transferred into or dispensed from a gasoline dispensing facility during 12 consecutive months.
(5)“Stage I vapor collection system” means a system where gasoline vapors are forced from a tank into a vapor-tight holding system or vapor control system through direct displacement by the gasoline being loaded.
(6)“Stage II vapor collection system” means a system where at least 90 percent, by weight, of the gasoline vapors that are displaced or drawn from a vehicle fuel tank during refueling are transferred to a vapor-tight holding system or vapor control system.
(7)“Substantially modified” means a modification of an existing gasoline-dispensing facility which involves the addition of one or more new stationary gasoline storage tanks or the repair, replacement or reconditioning of an existing tank.
(8)“Vapor control systems” means a system that prevents emissions to the outdoor atmosphere from exceeding 4.7 grains per gallon (80 grams per 1,000 liters) of petroleum liquid loaded.
