Tanks arranged in groups with a total capacity not exceeding how many gallons may be enclosed in a single dike enclosure?

• A. 250,000
• B. 400,000
• C. 500,000
• D. 600,000

Answer: (C)

A dike is a secondary containment barrier around tanks to catch spills. The amount of liquid that can be safely contained in a single dike enclosure is limited to keep spill volumes manageable and the containment reliable. For tanks grouped inside one dike, the total capacity must not exceed 500,000 gallons. If you need more storage, you must use additional dikes or other containment arrangements so each enclosure stays at or below that limit. So, 500,000 gallons is the maximum allowed for a single dike enclosure; smaller totals like 250,000 or 400,000 are okay, while 600,000 would require splitting into multiple dikes.
