PURPOSE: This rule identifies those persons required to obtain financial responsibility for releases of products from petroleum underground storage tanks.

1. (1) Rules 10 CSR 20-11.090—10 CSR 20- 11.115 apply to owners and operators of all petroleum underground storage tank (UST) systems except as otherwise provided in this rule.
2. (2) Owners and operators of petroleum UST systems are subject to these requirements if they are in operation on or after the date for compliance established in 10 CSR 20-11.091.
3. (3) State and federal government entities whose debts and liabilities are the debts and liabilities of a state or the United States are exempt from the requirements of 10 CSR 20- 11.090—10 CSR 20-11.115.
4. (4) The requirements of 10 CSR 20-11.090— 10 CSR 20-11.115 do not apply to owners and operators of any deferred or excluded UST system described in 10 CSR 20- 10.010(2) or (3).
