California ICC UST Inspector Practice Exam

Which item is NOT required on a hard copy of a monthly ATG monitoring test for a single-wall UST?

1. Water and fuel depth

2. Date and time

3. Temperature and pressure

4. Duration of test

The correct answer is: Temperature and pressure

In the context of a monthly Automatic Tank Gauge (ATG) monitoring test for a single-wall Underground Storage Tank (UST), specific documentation items are mandated to ensure proper monitoring and compliance with regulations. The key requirement is that the monitoring test results must demonstrate the performance of the UST system and any potential releases or leaks. The item that is not required on a hard copy of the monthly ATG monitoring test is the temperature and pressure. While temperature and pressure are important parameters in various technical contexts, they are not specifically mandated to be recorded on the monthly ATG monitoring report for single-wall USTs. Instead, the focus is on parameters directly tied to the assessment of product levels and any leaks, such as water and fuel depth, which track the actual contents and any accumulation of water in the tank. Furthermore, including the date and time is crucial for traceability, to ensure that tests are conducted on schedule and can be referenced accurately. The duration of the test also provides important context regarding the testing conditions and assurance that the monitoring was conducted properly. Therefore, while temperature and pressure can provide useful data in some contexts, they do not form part of the required documentation for the monthly ATG monitoring test of single-wall USTs.
