(d) "Average Monthly Throughput of Gasoline" means the average monthly throughput for the last previous months of June, July, and August during full operation.

(2) This Rule shall apply to all gasoline dispensing facilities except:

(a) transfers made to storage tanks or gasoline dispensing facilities equipped with floating roofs or their equivalent;

(b) transfers made to stationary gasoline storage tanks of less than 3,785 liters (1,000 gallons) capacity in place before July 1, 1979 and of less than 946 liters (250 gallons) installed after July 1, 1979;

(c) stationary gasoline storage containers of less than 2,082 liters (550 gallons) capacity used exclusively for the fueling of implements of husbandry, provided the containers are equipped with submerged fill pipe; and

(3) No owner or operator shall transfer, cause, or allow the transfer of gasoline from any gasoline tank truck into any stationary storage tank subject to this Rule, unless the tank is equipped with a submerged fill pipe and the vapors displaced from the storage tank during filling are processed by a vapor control system in accordance with paragraph (4) of this Rule.

(4) The vapor control system required by paragraph (3) of this Rule shall include one or more of the following:

(a) a vapor balance system (Stage I) between the stationary storage tank and the gasoline tank truck and a system that will ensure the vapor line is connected before gasoline can be transferred into the tank;

(b) a refrigeration condensation system or equivalent designed to recover at least ninety percent (90%) by weight of the organic compounds in the displaced vapor; or

(c) a control equipment system demonstrated to have control efficiency equivalent to or greater than provided under subparagraph (b) of this paragraph and approved by the Director.

(5) Each owner or operator of a gasoline dispensing facility subject to this Rule shall:

(7) Regardless of the applicability exemption under subparagraph (2)(d) of this Rule, all gasoline dispensing facilities that are subject to this Rule shall not disconnect an existing vapor balance system and shall maintain the system in proper working order in accordance with this Rule even if the facility's average monthly throughput of gasoline decreases to less than 4,000 gallons.
