A 7,500-gallon storage tank of crude oil has completely drained into the Cache La Poudre, Colorado's only designated National Wild and Scenic River, southeast of Fort Collins.
Spring floods caved in the riverbank and as a result the tank dropped from its foundation and broke a discharge valve, so all of the oil inside just flowed out right into the river.

How is it that after the spring floods this tank was not relocated or containment options were not put in place?
