There is no single answer for this query since UST systems cleanup costs depend on a number of factors. The costs can range from hundreds to millions of dollars depending on damage sustained by the environment and the facility.
Generally, UST systems cleanup costs depend on the size of the contamination and the cleanup regulations of the state. On average, you can expect upwards of $130,000 for cleanup operations in case an extensive patch of soil is contaminated. An example of high cost cleanup would be a spill that causes third party damages to water supplies. If on the other hand, only a small patch has to be removed or cleaned, $10,000 may be enough to cover costs.
Leaks that poison ground water can cost about $100,000 to $1 million depending on the extent of the contamination. Low UST Systems cleanup costs are sufficient for spills that can be cleaned up by absorbent material and if the material can be disposed off safely after it dries. In some states, less than 25 gallons of spilled product may be kept from regulatory authorities while other states may require reporting. A written report to a local agency can also be added to expenses.
