What does the abbreviation SIR stand for in UST management?

The abbreviation SIR in UST management stands for Statistical Inventory Reconciliation. This method is used to track inventory levels and identify any discrepancies that may indicate leaks in the underground storage tank system. By regularly comparing the amount of product added to the UST with the amount sold or dispensed, operators can statistically analyze this data to detect any irregularities over time.

This technique is crucial because it provides a systematic approach to monitoring the integrity of the tanks, which helps to ensure environmental safety and regulatory compliance. Effective use of SIR can indicate whether further investigation is needed, making it an essential tool for operators managing underground storage tanks.
