What is the minimum capacity of a used oil tank that UST financial responsibility requirements apply to?

The financial responsibility requirements for underground storage tanks (USTs) apply specifically to tanks that hold a substantial amount of used oil, with regulations stipulating that these requirements kick in when the tank's capacity reaches a minimum of 1,000 gallons. This threshold is in place to ensure that operators manage larger quantities of hazardous substances responsibly due to the potential risks associated with leaks or spills, which can have significant environmental and public health implications.

Understanding this capacity is critical for complying with regulations aimed at preventing environmental contamination and ensuring proper financial mechanisms are in place to address potential cleanup costs. Thus, the focus on a minimum tank capacity of 1,000 gallons aligns with the regulatory intent to establish robust oversight for more substantial operations that pose greater risks.
