An overflow control for liquid storage tanks is provided. Fluid overflowing from the inlet port or a vent port of a liquid storage tank is collected within a spill collection chamber that overlies the inlet port and the vent port. The spill collection chamber also overlies a spill storage chamber that receives liquid from the spill collection chamber when the liquid in the spill collection chamber raises to a level sufficient to enter the inlet port of the spill storage chamber. The spill collection chamber is formed in fluid tight relationship to the storage tank and to the spill storage chamber. The liquid storage tank may also be positioned within a dike that has a second spill collection chamber to capture overflow from the tank spill collection chamber.
