If you are a Texas UST operator with double-walled tanks and piping and are using interstitial monitoring for release detection, you no longer have to do inventory control as well. According to TCEQ, this rule went into effect February 15, 2024.
Revised Rule on Inventory Control for Retail Service Stations
Note, if you were still using SIR (Statistical Inventory Reconciliation) or automatic tank gauging (ATG 0.2 GPH test), you must still do inventory reconciliation.
Here at UST Training, we are often a fan of the “belts and suspenders” approach to leak detection, meaning the more methods of leak detection the better. However, due to the common measurement errors associated with inventory control, and the inherent simplicity of interstitial monitoring, we feel like this is a good move to simplify the UST rules while maintaining sufficient environmental protection.
