If your SIR system is capable of detecting a 0.2 gph leak, it meets the federal monthly monitoring requirements for the life of the tank and piping.

Sometimes

Not specified

False

True

Monthly monitoring under federal rules requires a leak detection method that can identify leaks at a rate of 0.2 gallons per hour or greater for the life of the tank and piping. Statistical Inventory Reconciliation uses monthly inventory data to spot discrepancies that indicate leaks, and when it’s configured to detect down to 0.2 gph, it meets that regulatory threshold. So, if your SIR system can detect a 0.2 gph leak, it satisfies the federal monthly monitoring requirement for the life of the tank and piping, provided the system is properly implemented, maintained, and data are accurately collected.
