Bulk Fuel Transfer Bunds –“Tanker Unloading” and “Trigger” Filling – ULP

Clean rainfall arriving on the catchment when the platform in not is use is directed to stormwatervia the Oil/Water Separation System

The risk of “Flammable” fuel spillage becomes apparent during fuel transfers

Stormwater discharge to the environment requires @ <5ppm hydrocarbon content = Current Industry Best Practice

Installation of a fuel spill retention and alarm system is required to manage this environmental risk

The accumulated minor spill retention capacity needs to be approx. 600 litres

The system requires the ability to isolate the stormwater discharge in the event of a major spill

The system requires an accumulated spill detection alarm to notify when the collection tanks requires evacuation of the floating layer of hydrocarbons

The Alarm system requires an Intrinsically Safe barrier and sensing module as the air space above the water level in the collection tank is classed as a zone 1 explosive hazard

Typical stormwater Rainfall IFD requires calculation, but will on most cases be < 20.0 L/sec

Collection pits or gratings are installed in the catchment pavement, with (fire rated) discharge pipework directed to the collection, treatment and isolation tank installed at ground level

Conduit materials and signal cable seals to be appropriate for Flammable Fuel applications

Product Ref- Option 1

LH-ESK-20-FL-LA – Refer drawing – Pre-cast concrete tank installed at ground level with 200mm inlet and outlet stubs, oil separation medium, spill retention capacity, spill isolation valve, spill sensing probe and remote alarm signaling capability

Tank Access Cover is located at Finished Surface level

Alarms to be local, with the option also available to communicate to a remote BMS
