Bulk Gasoline Terminals Including Truck and Trailer Loading
(1)
No terminal owner or operator, may allow VOCs to be emitted into the atmosphere in excess of 80 milligrams of VOC per liter of gasoline loaded from the operation of loading truck tanks, and truck trailers at bulk gasoline terminals with a daily throughputs of greater than 76,000 liters (20,000 gallons) per day of gasoline, determined by a thirty-day rolling average:(a)
The owner or operator of a gasoline loading terminal must only allow the transfer of gasoline between the facility and a truck tank or a truck trailer when a current leak test certification for the delivery vessel is on file with the terminal or a valid permit as required by OAR 340-232-0100 (Testing Vapor Transfer and Collection Systems)(1)(c) is displayed on the delivery vessel;(b)
The owner or operator of a truck tank or a truck trailer must not make any connection to the terminal’s gasoline loading rack unless the gasoline delivery vessel has been tested in accordance with OAR 340-232-0100 (Testing Vapor Transfer and Collection Systems)(1);(c)
The truck driver or other operator who fills a delivery truck tank and/or trailer tank must not take on a load of gasoline unless the vapor return hose is properly connected;(d)
All equipment associated with the vapor balance system must be maintained to be vapor tight and in good working order.(2)
Compliance with section (1) must be determined by testing in accordance with Method 33 on file with DEQ. [NOTE: This Method is in the DEQ Source Sampling Mnaual published at OAR 340-200-0035 (Reference Materials).]The method for determining compliance with section (1) are delineated in 40 CFR part 60, subpart XX, §60.503.(3)

The loading device must not leak when in use. The loading device must be designed and operated to allow no more than 10 cubic centimeters drainage per disconnect on the basis of 5 consecutive disconnects;(c)
All loading liquid lines must be equipped with fittings which make vapor-tight connections and which close automatically and immediately when disconnected;(d)
All vapor lines must be equipped with fittings which make vapor-tight connections and which close automatically and immediately when disconnected or which contain vapor tight unidirectional valves;(e)
Gasoline must be handled in a manner to prevent its being discarded in sewers or stored in open containers or handled in any manner that would result in evaporation. If more than 5 gallons are spilled, the operator must report the spillage in accordance with OAR 340-214-0300 (Excess Emissions and Emergency Provision: Purpose and Applicability) through 340-214-0350 (Excess Emissions and Emergency Provision: Enforcement Action Criteria);(f)
