Current through Register Vol. 24-14, July 15, 2024
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").
