A spill is classified as MINOR in inland waters if it is less than how many gallons?

• A. Less than 1,000 gallons.
• B. Less than 10,000 gallons.
• C. Less than 100 gallons.
• D. Less than 50,000 gallons.

Answer: (A)

Spill classifications guide how responders size up and approach cleanup. In inland waters, a spill is considered minor when its volume is under 1,000 gallons. This threshold reflects the point at which routine containment and cleanup resources are typically sufficient without triggering larger, more formal response actions. Larger spills—those at or above 1,000 gallons—require broader coordination and more extensive response efforts. While any amount under 1,000 gallons is smaller, 1,000 gallons is the official cutoff for the minor classification, and spills well above that threshold fall into higher categories.
