Retention is defined as?

• A. Creating a barrier in a waterway or depression (complete, overflow, underflow)
• B. Pushing or diverting product to a less hazardous area
• C. Collecting the product in a less hazardous area
• D. Creating a barrier not in waterway or depression

Answer: (C)

Retention means holding the spilled product in a designated, less hazardous area so it can be recovered without spreading. The key is to create a controlled space—using containment like berms, sumps, or absorbents—where the material is kept safe until cleanup. This focuses on gathering and preserving the product in a safe zone, rather than just diverting or blocking flow. The other options describe barriers or diversion strategies, not the act of collecting the product in a safe area for later recovery.
