If you have 110 USTs, you are required to maintain annual aggregate financial responsibility in the amount of _____.

• A. $1 million
• B. $2 million
• C. $5 million
• D. $10 million

Answer: (B)

Financial responsibility for underground storage tanks is a risk management requirement that ensures funds are available to cover corrective action and third‑party liability costs if a release occurs. The required aggregate amount scales with how many tanks you own. With 110 USTs, you’re in the tier that requires two million dollars of annual aggregate financial responsibility. This level matches the greater potential costs of managing leaks across a larger tank fleet. The smaller dollar amounts apply to facilities with fewer tanks, while higher amounts like five or ten million are used for much larger operations or specific regulatory circumstances. You can meet this FR requirement through insurance, a surety, a trust fund, or a letter of credit.
