§ 14.5. Tank filling operations.
Delivery operations shall comply with NFPA 385, Standard For Tank Vehicles For Flammable And Combustible Liquids, as well as the following requirements:
(1) The delivery vehicle shall be separated from an aboveground tank by at least 25 feet, except that no minimum separation distance is required for tanks that are filled by gravity.
(2) Tank filling may not begin until the delivery operator has determined tank ullage—available capacity.
(3) Tanks shall be filled through a liquid-tight connection. If the tank is filled by means of fixed piping, either a check valve and shutoff valve with a quick-connect coupling or a check valve with a dry-break coupling shall be installed in the piping where connection and disconnection is made between the tank and the delivery vehicle. This device shall be protected from tampering and physical damage.
