What is the total annual aggregate financial responsibility required for maintaining 110 USTs?

The total annual aggregate financial responsibility for maintaining underground storage tanks (USTs) is dictated by the regulations that ensure the owners and operators can cover the costs associated with cleanup and third-party liability in the event of a release. For 110 USTs, the required financial responsibility is typically calculated based on a standard of $1 million for the first tank and an additional $1 million for every additional 10 USTs.

In this case, the calculation would be as follows: The first tank requires $1 million, and each additional set of 10 tanks adds another $1 million. Therefore, for 110 tanks, the process would break down as:

• 1st tank: $1 million

• Next 10 tanks (10-20): $1 million

• Following 10 tanks (20-30): $1 million

• Continuing this pattern up to 110 tanks, you would have an additional 10 million dollars allocated for the last 10 tanks.

Adding this up gives a total of $2 million required to meet the financial responsibility standards for 110 USTs. This adherence ensures that operators are financially prepared for potential environmental liabilities associated with their operations.
