California ICC UST Inspector Practice Exam

Which element is NOT required to use an Automatic Tank Gauging (ATG) system for release detection?

1. The ATG must be certified for the types of tanks and stored contents

2. The amount of product in the tank must be sufficient for testing

3. The UST must be tested using the ATG at least once every 30 days

4. California law requires a quarterly maintenance system check of the ATG

The correct answer is: California law requires a quarterly maintenance system check of the ATG

An Automatic Tank Gauging (ATG) system is utilized for monitoring and detecting potential releases of fuel from underground storage tanks (USTs). The option indicating that California law requires a quarterly maintenance system check of the ATG is not a requirement for utilizing the ATG system for release detection. While regular maintenance and checks of the ATG systems are crucial for their functionality and to ensure compliance with safety regulations, it is not a prerequisite for the operation of the system itself for detection purposes. The other elements mentioned are essential for an ATG system to function effectively. Certification of the ATG is necessary to ensure that it is compatible with the specific tank types and the products stored in them, which helps maintain accurate readings and safety. Sufficient product volume in the tank is required for effective testing, as an inadequate amount could lead to false readings or an inability to perform a thorough evaluation of the tank's status. Lastly, regular testing of the UST using the ATG at least once every 30 days is a critical regulatory requirement that ensures timely detection of any leakage. This system of checks ensures understanding and compliance with the regulations surrounding UST operations.
