California ICC UST Inspector Practice Exam

When using an automatic tank gauge for leak detection, which information is NOT required in the post-test report?

1. Liquid volume

2. Fuel depth

3. Outside air temperature

4. Time and date of test

The correct answer is: Outside air temperature

When utilizing an automatic tank gauge for leak detection, the post-test report must include key information that is relevant to the integrity and functionality of the underground storage tank (UST) system. The information required typically includes the liquid volume and fuel depth, as these metrics are essential for determining accurate measurements of potential leaks. Additionally, the time and date of the test are crucial for establishing a timeline and understanding the test results in the context of environmental and operational conditions. The inclusion of outside air temperature is not mandated in the post-test report for leak detection purposes. While air temperature can have an effect on the physical properties of the fuel and can influence readings, it is not a required data point for evaluating the test results during the leak detection process. This unrequired data also indicates that the primary focus of leak detection is on the conditions within the tank and the fuel itself, rather than atmospheric conditions. Thus, omitting outside air temperature does not detract from the validity of the leak detection process or its reporting standards.
