A spill of 1,500 gallons occurs inland. Which discharge classification applies?

• A. Medium discharge inland
• B. Minor discharge inland
• C. Major discharge inland
• D. Not classified

Answer: (A)

Discharge classifications are based on the amount spilled and where it occurs. Inland releases are categorized as minor, medium, or major. A spill of about 1,500 gallons is too large to be considered minor, but not large enough to be a major discharge, so it falls into the medium category. This level guides how the response is coordinated and what reporting is required. Major discharges involve a much larger volume and more extensive emergency action, while minor spills are smaller and require less intensive response. Not classified wouldn’t apply here because the volume is known and falls within a defined range.
