What is the function of a spill bucket?

• A. To collect rainwater
• B. To contain spills that occur during fuel delivery
• C. To seal the fill cap
• D. To measure tank inventory

Answer: (B)

A spill bucket is a containment feature at the fueling fill point that is specifically designed to catch and hold any fuel that spills during delivery. When a tanker unloads into an underground storage tank, small spills can happen, and the spill bucket provides a watertight receptacle to capture that fuel so it can be cleaned up easily and doesn’t soak into soil or reach groundwater.

This isn’t used for collecting rainwater, sealing the fill cap, or measuring tank inventory—the rainwater system, the cap’s seal, and inventory gauges serve those separate purposes. The spill bucket’s job is solely to contain fueling spills to protect the environment.
