California UST System Operator Practice Test

A spill or overflow of how many gallons must be reported if it results in a release of petroleum to the environment?

1. 10 gallons

2. 25 gallons

3. 50 gallons

4. 100 gallons

The correct answer is: 25 gallons

In California, the reporting requirement for a spill or overflow of petroleum is triggered when the incident involves 25 gallons or more that results in a release to the environment. This regulation is in place to ensure that significant spills are monitored and managed to mitigate environmental impact. By establishing a threshold at 25 gallons, authorities can prioritize responses to more substantial spills that have a higher potential for harm to both the environment and public safety. Smaller spills, while still potentially problematic, do not require the same level of oversight under this specific regulation. This distinction helps streamline reporting processes and ensures that resources are allocated effectively in response to more serious incidents.
