Which spill size category is defined as Minor?

• A. Less than 10,000 gal
• B. 10,000-100,000 gal
• C. Over 100,000 gal
• D. 5,000 gal

Answer: (A)

Spill size categories are defined by numeric thresholds so responders can quickly classify the incident and determine the appropriate level of response. Minor is defined as spills under 10,000 gallons. This threshold matters because it guides decisions about resources, notification, and coordination; spills below this amount are typically managed with local response unless other factors require escalation. Therefore, the descriptor that defines the Minor category is "Less than 10,000 gal," since it covers all spills below that limit. A specific value like 5,000 gallons is a valid example of a minor spill but it isn’t the category label itself, which is about the threshold. The other options describe larger spill ranges or a single value that does not define the Minor category.
