The owner or operator of a storage tank system shall follow the procedures in s. ATCP 93.575 when any of the following conditions exist or when ordered to do so by the department:

1. (1) Operating conditions. Unusual operating conditions exist, such as erratic behavior of product dispensing equipment, loss of product from the tank system, an unexplained presence of water in the tank, or water or product in the interstitial space of a secondarily contained system.

   Note: Significant damage to equipment would be considered to be an unusual operating condition that could result in needing to perform the assessments specified in s. ATCP 93.575.

2. (2) Monitoring results. Results from a leak detection method, including an alarm, indicate that a release may have occurred.
3. (3) Off-site impacts. Off-site impacts appear, such as the presence of contaminated soils or free product, dissolved phase product or vapors in soils, basements, sewer or utility lines, or nearby waters of the state.
4. (4) Inventory verification. Inventory verification results indicate that a required method of leak detection has failed.
