BOTTOM LOADING - means the filling of a tank through a submerged fill line.
BULK GASOLINE PLANT - means a gasoline storage and transfer facility that receives more than ninety percent of its annual gasoline throughput by transport tank, and reloads gasoline into transport tanks. See also "gasoline station" and "gasoline loading terminal."
CERTIFIED VAPOR RECOVERY SYSTEM - means a stage II vapor recovery system which has been certified by the California Air Resources Board.
CLOSED REFINERY SYSTEM - means a disposal system that will process or dispose of those VOC collected from another system.
CUTBACK ASPHALT - means an asphalt that has been blended with more than seven percent petroleum distillates by weight.
DISPOSAL SYSTEM - means a process or device that reduces the mass quantity of the uncontrolled VOC emissions by at least ninety percent.
GASOLINE - Means a petroleum distillate having a true vapor pressure greater than 28.0 kilopascals (kPa) (4 pounds per square inch absolute -p.s.i.a.) - at 20 degrees Celsius (20 C) temperature, that is a liquid at standard conditions of 102.9 Kpa (14.7 psi) and 20 C, and is used as a fuel for internal combustion engines.
GASOLINE STATION - means any facility dispensing gasoline into fuel tanks of motor vehicles, from stationary storage tanks. See also "bulk gasoline plant" and "gasoline loading terminal."
GASOLINE LOADING TERMINAL - means a gasoline transfer facility that receives more than ten percent of its annual gasoline throughput solely or in combination by pipeline, ship or barge, and loads gasoline into transport tanks. See also "bulk gasoline plant" and "gasoline station."
LEAK FREE - means a liquid leak of less than four drops per minute.
PETROLEUM REFINERY - means a facility engaged in producing gasoline, kerosene, distillate fuel oils, residual fuel oils, lubricants, asphalt, or other products by distilling crude oils or redistilling, cracking, extracting or reforming unfinished petroleum derivatives.
PROCESS UNIT - means all the equipment essential to a particular production process.
PROPER ATTACHMENT FITTINGS - means connecting hardware for the attachment of fuel transfer or vapor lines which meets or exceeds industrial standards or specifications and the standards of other agencies or institutions responsible for health and safety.
REID VAPOR PRESSURE - means the true vapor pressure of volatile organic compounds at 37.8 degrees Celsius (100 degrees Fahrenheit) temperature.
STAGE II - means gasoline vapor recovery during motor vehicle refueling operations from stationary tanks.
SUBMERGED FILL LINE - means a pipe, tube, fitting or other hardware for loading liquid into a tank either a discharge opening flush with the tank bottom; or with a discharge opening entirely below the lowest normal operating drawoff level or that level determined by a liquid depth two and one half times the fill line diameter when measured in the main portion of the tank, but not in sumps or similar protrusions.
SUBMERGED LOADING - means the filling of a tank with a submerged fill line.
SUITABLE CLOSURE or SUITABLE COVER - means a door, hatch, cover, lid, pipe cap, pipe blind, valve or similar device that prevents the accidental spilling or emitting of VOC. Pressure relief valves, aspirator vents or other devices specifically required for safety and fire protection are not included.
TRANSPORT TANK - means a container with a capacity greater than one thousand liters (260 gallons) used for transporting gasoline, including but not limited to, tank truck, tank trailer, railroad car, and metallic or nonmetallic tank or cell conveyed on a flatbed truck, trailer or railroad car.
THROUGHPUT - means the amount of material passing through a facility.
TRUE VAPOR PRESSURE - means the equilibrium partial pressure of an organic liquid (determined with methods described in American Petroleum Institute Bulletin 2517, "Evaporation Loss from Floating Roof Tanks," 1962).
TURNAROUND or PROCESS UNIT TURNAROUNDS - means the shutting down and starting up of process units for periodic major maintenance and repair of equipment, or other planned purpose.
UPGRADED - means the replacement or modification gasoline storage tank(s) and/or piping system(s) that exceeds 50% of the replacement cost.
VAPOR BALANCE SYSTEM - means a combination of pipes or hoses which create a closed system between the vapor spaces of an unloading tank and receiving tank such that the vapors displaced from the receiving tank are transferred to the tank being unloaded.
VAPOR BALANCING - means use of a vapor balance system.
VAPOR RECOVERY SYSTEM - means a process which prevents emission to the atmosphere of volatile organic compounds released by the operation of any transfer, storage, or process equipment.
VOLATILE ORGANIC COMPOUND or VOC - means an organic compound that participates in atmospheric photochemical reactions. This excludes all compounds determined to have negligible photochemical reactivity by the U.S. Environmental Protection Agency and listed in 40 CFR 51.100(s).
WAXY, HEAVY POUR CRUDE OIL - means a crude oil with a pour point of 10 C or higher (determined by the American Society for Testing and Materials Standard D97-66, "Test for Pour Point of Petroleum Oils").
