California UST System Operator Practice Test

Which equipment is required to have a first three-year test or inspection at installation for UST systems installed after October 13, 2015?

1. Single-wall spill buckets

2. Overfill prevention valves

3. Automatic shutoff devices

4. All of the above

The correct answer is: All of the above

The requirement for a first three-year test or inspection at installation for UST systems installed after October 13, 2015, includes several critical components designed to ensure the safety and regulatory compliance of underground storage tanks. Each of these components plays a vital role in preventing spills and leaks, thereby protecting the environment and public health. Single-wall spill buckets are designed to catch spills during the transfer of fuel to the UST, minimizing the environmental impact of any potential spills. Their testing ensures they are functioning properly to contain overflow and leaks effectively. Overfill prevention valves are essential for preventing the tank from being overfilled. When properly tested, these valves can significantly reduce the risk of spillage during refueling operations by ensuring that the tank does not exceed its capacity. Automatic shutoff devices are critical for quickly stopping the flow of product in the event of a leak or overfill scenario. Regular inspection and testing of these devices are necessary to verify that they activate correctly and prevent accidents. Because each of these components contributes to the overall integrity and safe operation of UST systems, the requirement for their initial three-year testing or inspection aligns with regulatory standards aimed at minimizing risks associated with fuel storage. Consequently, all these pieces of equipment must undergo testing or inspection after installation to
