Petroleum underground storage tank owners and operators are required to have the funds to pay for the cleanup and other damages that may occur from a release from their underground storage tank (UST) systems. This requirement is known as financial responsibility. Owners and operators of regulated UST systems must comply with the financial responsibility requirements (PUB 218). Both owners and operators are responsible for compliance, although only one party needs to obtain financial responsibility.

The Missouri Department of Natural Resources requires proof of financial responsibility from all applicable owners and operators:

  • After a release or suspected release from a UST system
  • When a new UST system is installed
  • During a site inspection

Financial responsibility must cover cleanups, third party property damages and third party bodily injuries. The required amount of financial responsibility is typically $1 million per occurrence and $1 million dollars annual aggregate with the following exceptions:

  • Non-marketers with less than 10,000 gallons per month throughput need only obtain $500,000 per occurrence
  • Owners of more than 100 UST systems nationwide must obtain $2 million annual aggregate coverage

Mechanisms to meet the requirements of financial responsibility include

Specific requirements for each mechanism can be found in the Missouri Code of State Regulations (CSR), 10 CSR 20-11.  Examples and required wording for each are included in the appendices to the regulations, beginning on page 14.  The Missouri Code of State Regulations is available from the Missouri Secretary of State's Office, 573-751-4015.
