Not a site, but eyeballs-on reference from (altogether too many) years ago.
The total facility consisted of two raised tanks (retired tank cars) and a tin shed similar to a large garden shed. Inside the shed, two pumps, a small boiler (fired with #2 diesel) and stowage for the various hoses used. The shed had electric power connections and the pumps were electric motor centrifugal type.
#2 diesel flows easily, so it only required a hose connection to the tank car's bottom drain fitting. Bunker C, OTOH, has the consistency of roof tar - hence the boiler, which was connected with insulating hoses to the in-tank heater coil (and to the storage tank heater coil) to facilitate unloading. Once reasonably hot, the heavy oil could be pumped to the storage tank.
In those pre-EPA days, oil spills simply soaked into the ground. The area looked like poor-quality asphalt. The only other item - several large NO SMOKING signs.
