California UST System Operator Practice Exam - Study Guide & Practice Test

The requirement for owners and operators of 100 or fewer underground storage tanks (USTs) to have aggregate coverage for taking corrective action and compensating third parties is set at $1 million. This amount is deemed sufficient to address potential liabilities that could arise from leaks or spills associated with UST operations. Corrective action refers to the necessary measures taken to remedy any environmental contamination that may occur, while compensation for third parties involves covering damages or injuries that might result from such incidents.

Having a $1 million coverage ensures that there are adequate financial resources available for addressing the remediation of any spills, as well as compensating individuals or businesses that may be negatively affected by pollution. This requirement is part of regulatory frameworks aimed at protecting public health and the environment by ensuring that UST operators are financially responsible for the risks their operations may pose.
