Section 096-118-3 - Definitions
Current through 2024-38, September 18, 2024
The following terms, as used in this Chapter, have the following meanings:
A. Balance nozzle . "Balance nozzle" means the nozzle used to dispense gasoline at a Stage II gasoline dispensing facility where vapors are collected through direct displacement.
B. CARB. "CARB" means the California Air Resources Board, Sacramento, CA 95812.
C. Gasoline dispensing facility. "Gasoline dispensing facility" means any stationary facility, including those located at marinas and airports, which dispenses gasoline into the fuel tank of a motor vehicle, motor vehicle engine, nonroad vehicle, or nonroad engine, including a nonroad vehicle or nonroad engine used solely for competition. These facilities include, but are not limited to, facilities that dispense gasoline into on and off-road, street, or highway motor vehicles, lawn equipment, boats, test engines, landscaping equipment, generators, pumps, and other gasoline-fueled engines and equipment.
D. Pressure/Vacuum (PV) vent valves. "Pressure/Vacuum (PV) vent valves" means a relief valve installed on a gasoline storage tank and designed to open at specific pressure and vacuum settings to protect the system from excessive pressure or vacuum.
E. Stage I vapor balance system. "Stage I vapor balance system" means the appropriate fittings and connectors at both the gasoline dispensing facility and the tank truck that completes a closed vapor loop when the tank truck receives gasoline from or delivers gasoline to the stationary storage tank of a gasoline dispensing facility. A closed vapor loop includes a vapor tight line from the tank truck to the stationary gasoline storage tank of a gasoline dispensing facility and a connection system that will not allow delivery of gasoline to the stationary gasoline storage tank of a gasoline dispensing facility unless there is a vapor tight connection.
F. Stage II vapor recovery system. "Stage II vapor recovery system" means a system that limits the discharge to the atmosphere of gasoline vapors displaced during the dispensing of gasoline into motor vehicle fuel tanks and that has demonstrated 95 percent by weight or greater Volatile Organic Compound (VOC) control efficiency by:
Aftermarket and rebuilt parts may be included as part of the Stage II vapor recovery system provided they are CARB-approved aftermarket and rebuilt parts. The system must utilize coaxial hoses at the dispensers and may not contain any components (e.g., remote vapor check valves in balance type systems) that would significantly impede the performance of the functional tests required in Section 8(B) of this Chapter.
