How frequently must tank integrity tests be conducted if using Statistical Inventory Reconciliation?

1. Every year

2. Every two years

3. Every three years

4. Every five years

The correct answer is: Every two years

Tank integrity tests must be conducted every two years if using Statistical Inventory Reconciliation (SIR) because this timing aligns with regulatory requirements and best practices for monitoring underground storage tanks (USTs). SIR is a method used to assess the accuracy of inventory records and detect leaks in the tank systems. To effectively ensure the integrity of the tanks and to minimize environmental risks, performing the integrity tests at this interval allows for timely detection of potential issues. By adhering to a two-year schedule, operators can stay compliant with state and federal regulations, which are designed to safeguard public health and the environment. This frequency strikes a balance between maintaining operational oversight and preventing undue expenditures by ensuring that tanks are regularly evaluated without being tested excessively, which could lead to resource wastage. Thus, using SIR with a two-year testing frequency is a practical and efficient strategy for managing tank integrity.
