In inland waters, which spill volume would be considered minor?

• A. 250 gallons
• B. 500 gallons
• C. 1,500 gallons
• D. 5,000 gallons

Answer: (B)

Spill severity in inland waters is judged by how much product escapes and how easily it can spread. A minor spill is one small enough to be controlled and cleaned up with basic resources and doesn't trigger a large-scale response. In the guidelines used for this context, the threshold for a minor inland-water spill is up to about 500 gallons. A spill of 500 gallons fits that category because it can typically be addressed with standard spill kits, absorbents, and simple containment measures without escalating the response. Larger volumes—1,500 gallons or 5,000 gallons—have far greater potential environmental impact and require more extensive containment, cleanup, and reporting, so they are not considered minor. Among the options, 500 gallons best fits the minor classification.
