Hatch-loading systems must include a loading arm with a vapor collection system adapter, a vapor-tight seal between the adapter and hatch, and a method of preventing drainage of liquid gasoline from the loading arm when it is removed from the hatch or for complete drainage of the loading arm before such removal;

(iii) a vapor space connection on the gasoline transport vehicle equipped with vapor-tight fittings that automatically and immediately close upon disconnection to prevent the release of gasoline vapors when loading is through means other than hatches;

(iv) a connecting device between the gasoline transport vehicle and the dispensing equipment that interrupts the flow of gasoline to prevent overfilling and spillage; and

(v) a system that prevents the flow of gasoline into gasoline transport vehicles unless the fuel product line and vapor collection system are both connected so as to prevent liquid product leaks or vapor loss;

(4) the design of any connecting devices required by this Part to control gasoline vapor emissions while loading gasoline transport vehicles at a gasoline bulk plant must be standardized to provide compatibility between different bulk plants and transport vehicles; or connecting adapters must be provided and used. The owner or operator of the gasoline bulk plant is responsible for ensuring that the adapter is properly connected before dispensing gasoline. Connecting adapters must be adequate to ensure that the vapor collection system is vapor-tight.

(d) Gasoline loading terminals. No person subject to this Part may load gasoline into a gasoline transport vehicle from any gasoline loading terminal unless the gasoline loading terminal is equipped with gasoline vapor collection and vapor control systems which are operating and in good working order and that satisfy the following requirements:

(1) The gasoline vapor collection and control systems must capture gasoline vapors during loading and unloading of gasoline transport vehicles, and must condense, absorb, adsorb or combust the gasoline vapors so emissions do not exceed 0.67 pounds per 1,000 gallons of gasoline loaded or unloaded. Any equivalent control system is acceptable. Test methods to determine the level of gasoline vapors which are acceptable to the commissioner must be used to determine compliance with this standard. Test methods described in Appendix A of 40 CFR part 60 are considered to be acceptable methods (see table 1, section 200.9 of this Title).

(2) A vapor collection system required at a gasoline loading terminal consists of:

(i) hatch-loading systems must include a loading arm with a vapor collection system adapter, a vapor-tight seal between the adapter and hatch, and a method of preventing drainage of liquid gasoline from the loading arm when it is removed from the hatch or for complete drainage of the loading arm before such removal;
