A spill of 25,000 gallons falls into which spill size category?

• A. Minor is less than 10,000 gal
• B. Medium is 10,000-100,000 gal
• C. Major is over 100,000 gal
• D. Large is 50,000-150,000 gal

Answer: (B)

Classification hinges on predefined spill-size ranges. A spill of 25,000 gallons sits between 10,000 and 100,000 gallons, which places it in the Medium category. The other ranges don’t fit: Minor is under 10,000 gallons, Large starts at 50,000 gallons and goes up to 150,000, and Major is over 100,000 gallons. Knowing the correct range helps determine the appropriate level of response and reporting.
