Petroleum underground storage tank (UST) owners and operators are required to have the funds to pay for cleanup and other damages that may occur from a release from their USTs. This requirement is known as financial responsibility. Detailed information about the financial responsibility requirements can be found in Chapter 3 of the UST regulations (10 CSR 26-3).

Who must obtain financial responsibility?
Owners and operators of operating petroleum USTs must comply with the financial responsibility requirements. Both parties are responsible for compliance, although only one party, either owner or operator, needs to obtain financial responsibility.

Why is financial responsibility important?
