98 Vapour collection systems

(1) A large loading plant must have a vapour collection system that ensures all vapour displaced from delivery tanks on tanker trucks during loading operations is collected and conveyed by a vapour line to—

(a) a vapour disposal system, or

(b) a vapour recovery system.

(2) The vapour line must not permit the escape of vapour into the atmosphere.

(3) The vapour lines must have an internal diameter of not less than 65% of the largest fill-line used for connection to the delivery tank.

(4) Each vapour line and liquid line between the large loading plant and a delivery tank on a tanker truck must have a fitting that—

(a) connects securely to the delivery tank, and

(b) does not permit the escape of vapour or liquid, and

(c) closes automatically when disconnected.
