RULE 3.9 ORGANIC LIQUID STORAGE AND TRANSFER (Adopted 6/91, Amended 6/2/14)
For the purposes of this rule, the organic liquid’s true vapor pressure may be obtained from Table 1, provided that the actual storage temperature of the organic liquid does not exceed the corresponding maximum temperature listed in the table, or may be determined according to the test method specified in Section F.1.b, under actual storage conditions.
of this Rule shall not apply to storage tanks at gasoline dispensing facilities subject to Rule 3.8
D.1 shall not apply to floating roof tanks.
DELIVERY VESSEL: Any cargo tank, tank truck, trailer, or railroad tank car that is designed and equipped to receive, transport, and deliver organic liquid.
EXTERNAL FLOATING ROOF TANK: A storage tank equipped with a floating roof exposed to the atmosphere that floats on the surface of the stored liquid.
FIXED ROOF TANK: A storage tank with a roof that is permanently affixed to the shell of the storage tank.
GASOLINE: Any petroleum distillate or petroleum distillate/alcohol blend having a Reid vapor pressure of 4 pounds per square inch absolute or greater as determined by a method specified by test methods ASTM DM2879-97 (2007), ASTM D323-06, or ASTM D5191-07.
GASOLINE BULK PLANT: Any gasoline loading facility where primary delivery of gasoline to a storage tank is other than by pipeline.
GASOLINE DISPENSING FACILITY: Any stationary facility which receives gasoline from delivery vessels and dispenses gasoline directly into the fuel tanks of motor vehicles.
INTERNAL FLOATING ROOF TANK: A storage tank equipped with a fixed roof and a floating roof that floats on the surface of the liquid being contained (but not necessarily in complete contact with it).
LOADING FACILITY: Any organic liquid or gasoline loading rack or set of such racks that load organic liquid or gasoline into delivery vessels.
ORGANIC LIQUID: Any liquid which contains any volatile organic compound or mixtures of volatile organic compounds with a true vapor pressure of 0.5 psia or greater under actual storage or loading conditions except liquefied petroleum gases.
PRESSURE TANK: A storage tank that maintains working pressures sufficient at all times to prevent organic vapor or gas loss to the atmosphere, except under emergency conditions.
REID VAPOR PRESSURE: The absolute vapor pressure of an organic liquid except liquefied petroleum gases, as determined in accordance with the test method specified in Section F.1.a.
STORAGE TANK: Any container designed and equipped for storage of an organic liquid.
SUBMERGED FILL PIPE:
Top Loading: Any fill pipe which has the discharge opening entirely submerged when the liquid level is 6
inches above the bottom of the tank.
Side Loading: Any fill pipe which has the discharge opening entirely submerged when the liquid level is 18
inches above the bottom of the tank.
TRANSFER EQUIPMENT: All components of the liquid loading line between the liquid pump and the delivery vessel, and the vapor return line from the delivery vessel to the storage tank, or to and including the vapor recovery system.
TRUE VAPOR PRESSURE: The equilibrium partial pressure exerted by an organic liquid as determined in accordance with the test method specified in Section F.1.b.
VAPOR RECOVERY SYSTEM: Any vapor gathering system which is capable of collecting and returning discharged VOC vapors and gases during loading of organic liquids into cargo tanks or delivery vessels, back to a stationary storage tank, or into an enclosed process system.
VAPOR TIGHT: A vapor leak of less than 10,000 ppm hydrocarbon concentration, as determined by EPA Reference Method 21, using an appropriate analyzer calibrated with methane.
stationary storage tank of more than 39,630 gallons (150,000 liters) capacity, unless such storage tank is a pressure tank or is designed and equipped with one of the
vapor loss control devices specified in Sections D.3 or D.4.
Consist of two seals, one above the other; the one below shall be referred to as the primary seal, and the one above shall be referred to as the secondary seal.
The true vapor pressure of the organic liquid stored in
the tank is less than 11.0 psia under actual storage conditions as determined in accordance with the test
method specified in Section F.1.b.
The organic liquid is not visible above the floating
The floating roof is in contact with the liquid contents
(but not necessarily in complete contact with it) at all times except when the storage tank is completely emptied, and subsequently refilled.
The system shall have an abatement efficiency of at least 90% by weight as determined in accordance with the test methods specified in Section F.1.c, F.1.d, and F.1.e, as applicable.
All piping, fittings, and pressure-vacuum relief valves
associated with the fixed roof tank and the vapor recovery system shall be constructed and maintained in a vapor tight condition unless the pressure within the fixed roof tank exceeds the valve setting pressure.
into a delivery vessel shall be equipped with a system that prevents at least 90% by weight of the gasoline vapors displaced from entering the atmosphere.
determined in accordance with EPA Method 25A, Determination of Total Gaseous Organic Concentration Using a Nondispersive Infrared Analyzer, calibrated with methane gas; or EPA Method 25A, Determination of Total Gaseous Organic Concentration Using a Flame Ionization Analyzer, calibrated with methane gas, as applicable.
