For owners with 100 or fewer tanks, what is the required aggregate amount of financial responsibility?

The correct answer is based on the regulatory requirements for financial responsibility related to underground storage tanks (USTs). For owners who have 100 or fewer tanks, the required aggregate amount of financial responsibility is indeed $1 million. This figure is established to ensure that tank owners can cover potential damages and liabilities associated with leaks or other environmental impacts resulting from their UST systems. The $1 million threshold serves as a baseline to protect public health and the environment, ensuring that adequate resources are available for cleanup and remediation efforts if a release occurs.

This requirement aligns with federal and state regulations aimed at managing risks associated with USTs, reinforcing the necessity for operators to maintain robust financial mechanisms to address potential environmental issues. Proper financial responsibility not only aids in compliance with the law but also fosters accountability among UST owners regarding the environmental impacts of their operations.
