If a group of tanks has total capacity of 450,000 gallons, can they be enclosed in a single dike enclosure?

• A. Not specified
• B. Only if additional dikes
• C. No
• D. Yes

Answer: (D)

Containment is about making sure the diked area can hold the full contents of all tanks inside it, plus some extra for rain and splash. If the group inside a dike has a total capacity of 450,000 gallons, the dike can be sized to hold at least that amount with appropriate freeboard. So a single dike enclosure is feasible, provided the dike is designed to contain 450,000 gallons (plus the required freeboard). The other options aren’t needed here because the situation isn’t inherently restricted; a single well-designed dike can contain that total, rather than requiring multiple dikes or being unspecified.
