Statistical Inventory Reconciliation (SIR)

Our Statistical Inventory Reconciliation (SIR) software simplifies environmental compliance requirements – for both US State Program Approved (SPA) and non-SPA states – while reducing fuel losses and equipment maintenance costs.

EPA-certified as among the most accurate release detection methods, our SIR solution has a leak detection threshold of 0.05 gallons per hour (0.0189 litres per hour) with greater than 99.6% accuracy. This means more PASS results.

The depth and accuracy of our software means we can identify the root cause of fuel variances/losses, whereas other vendors just ask more questions. We can process accurate SIR results with only 26 days of data which is critical in meeting compliance reporting requirements.

Our SIR solution adds up to more effective compliance, fewer and reduced cost of investigations and lower fuel losses. In fact, networks using our software have reduced their fuel losses by between 10% – 32%.

Reporting suite

Management summaries: Dashboard snapshot of compliance results across your network

Compliance reporting: Primary regulatory compliance document for each tank delivered monthly to meet federal or state reporting requirements 

KPI reports: Monthly report summarizing overall fuel gain or loss trends as well as pass, fail, inconclusive or no data results for all sites

Exception reporting: Featuring all fail or inclusive results to help diagnose issues such as short deliveries, erroneous blend ratios, miscalibrated meters etc

Tank gauge calibrations: Monthly list of ATG’s and dip sticks that have suspected strapping chart errors creating delivery day losses or gains

Investigation summary: For any investigations conducted, a summary of actions is provided in both management and weekly reporting.

The Leighton O’Brien advantage

Unmatched analytics and intelligence: We apply more than 80 algorithms to comprehensively screen your data, providing a highly accurate representation of what’s happening in your tank system.

Tank gauge calibration: ATGs are frequently out of calibration by +/- 1% or more. Our software identifies and corrects the error to detect real losses.

Improved data quality: Our software smooths out data quality issues which not only highlights potential operational problems such as equipment and strapping chart errors but unacceptable fuel losses.

Third-party certification: US EPA-certified with a leak detection threshold of 0.05 gallons per hour, SIR provides fewer false Fails and Inconclusives and more accurate Pass results.

Case study

  • A fuel retailer with 2,000 tanks (700 sites) was utilizing ATGs for environmental compliance and scheduled meter calibrations to monitor meter drift. 
  • Through an in-house gross variance Wetstock loss process, the retailer was experiencing a fuel loss rate of 0.31% of daily sales. 
  • After deploying Leighton O’Brien’s SIR solution, the accuracy in the software was able to reduce fuel losses by 32% (down to 0.21% of daily sales), increase sales volumes by 653 gallons (~930 gallons per site) and recoup $1,959,000 in sales revenue (~$2,800 per site).

Adding fuel polishing and restoration to our product line through Leighton O’Brien is another valued service to address fuel quality issues. We are extremely pleased with the design and efficiency of the units and provides a professional platform that fits our model well.
