wood. in an area where there is a chance of flooding 0.2% annually or once every 500 years, with water deeper than 1 foot. See Flood Zone Viewer map in Attachment 3. Hydrostatic Analysis in Attachment 3 indicates that the tank will not become buoyant, even if fully submerged in a 500 year flood. Similarly, sliding forces from the design earthquake are insufficient to cause the tank to move or to overturn. Seismic/Anchoring findings: The tank as designed and operated, and the containment area in which it is located are adequately anchored and meet minimum seismic s f standards. Initials: Leak Test 66265.192(k)(10): Brief description of leak test, including type of test used, and results of test: This tank was integrity tested based on the Steel Tank Institute's Standard SP001, "Standard for the Inspection of Aboveground Storage Tanks" (STI SP001) and recommendations from the manufacturer. This standard provides recommended integrity testing schedules based on risk to the environment, considering factors such as spill control, release detection methods, and storage capacity. Table 5.5, "Table of Inspection Schedules", of STI SP001 recommends tanks of this size and type undergo periodic, visual, documented inspections to assess general AST conditions. These inspections may be conducted by the AST owner and without suspending AST operations or removing the AST from service. Holt of California conducts these types of inspections on a daily basis. The tank inspector reviewed Holt of California inspection logs and conducted his own assessment based on the attached checklist. The tank was deemed to be in proper working order and the integrity sound. Sample inspection logs are located in Attachment 2. Integrity testing findings: Based on the above noted integrity test and the results obtained from that test, the tank has sufficient integrity for its intended use.
