All are examples of acceptable release detection for tanks, except:

• A. Impressed current cathodic protection
• B. Automatic tank gauging
• C. Statistical inventory reconciliation
• D. Soil-vapor monitoring

Answer: (A)

Release detection in tanks involves methods that actually identify leaks or losses of product. Impressed current cathodic protection is a corrosion-control system. It’s designed to protect the metal tank from rusting by applying a protective electrical current, not to monitor for leaks or reveal unreconciled inventory. In contrast, automatic tank gauging tracks inventory and alarms on unexplained losses, statistical inventory reconciliation analyzes inventory records for discrepancies, and soil-vapor monitoring tests the surrounding soil for leaked vapors. Because ICCP doesn’t detect leaks, it’s not considered an acceptable release-detection method.
