Environmental Protection (Recovery of Vapours from the Transfer of Organic Liquids) Regulations 1995

The person in charge of a delivery tank must ensure that, when the delivery tank is being used to receive organic liquids from a bulk fuel terminal or to transfer organic liquids to an underground fuel tank, the delivery tank is fitted with the equipment referred to in subregulations (2), (3) and (4).

The following equipment is required to be fitted under subregulation (1) —

a vapour handling system for organic vapours and gases displaced by the transfer of liquids to or from the underground fuel tank, that comprises of —

a vapour transfer valve on each delivery tank connecting that tank, through a manifold if desired, to a vapour line coupling;

a vapour return hose of vapour‑tight construction fitted to connect at one end with the vapour line coupling or couplings on the vehicle, and at the other end to a vapour return coupling at the liquid unloading location; and

couplings on vapour return hoses that make a vapour‑tight connection with the respective fittings on the vehicle;

an overfill protection device located in each delivery tank that is designed to stop the flow of liquid into the tank as near as practicable to the level of minimum ullage;

pressure‑vacuum valves on all vents to the atmosphere, except on emergency vents, which are set to be closed when the pressure in the tank is between 15 kilopascals above, and 3 kilopascals below, ambient pressure;

couplings on liquid lines on the delivery tank that make a liquid‑tight connection with their respective mating fittings and that close automatically when disconnected;

couplings on liquid hoses that make a liquid‑tight connection with their respective mating fittings; and

vapour‑tight hatch gaskets.

The vapour transfer valve referred to in subregulation (2)(a)(i) must be interlocked so as to be in the open position whenever liquid is being transferred to or from the delivery tank, and to be closed unless the appropriate vapour line coupling is positively connected to a vapour return hose.

The internal diameter of the hose referred to in subregulation (2)(a)(ii) must be not less than 65% of the internal diameter of the largest liquid transfer hose carried by the vehicle.

The person in charge of a delivery tank must ensure that all equipment required under this regulation to be fitted in respect of the delivery tank operates in a proper and efficient manner and is operated correctly.
