06.03 How are aboveground tanks filled?

Aboveground tanks are filled by several methods:

(a) delivery tuck is pump equipped and the delivery nozzle is directly attached to a top of tank fitting. Access stairs and platforms are typically provided for safe personnel access to the top of the tank. This system has the benefit of simplicity and the drawback of safety issues associated with moving heavy fuel hoses up stairs or ladders.

(b) delivery truck is pump equipped and the delivery hose is connected to a fill pipe at a ground mounted spill container. This system provides for personnel safety while increasing the complexity of the fill system.

( c) delivery truck is gravity drop and a stationary transfer pump mounted at grade moves fuel from the truck to the aboveground fuel tank through the fill pipe. This system has the benefit of being able to utilize the broader availability, and sometimes lower cost, of gravity drop fuel trucks. The drawback is the capital cost of providing the stationary pump system.
