1. “Board” means the Iowa comprehensive petroleum underground storage tank fund board.
2. “Corrective action” means an action taken to reduce, minimize, eliminate, clean up, control, or monitor a release to protect the public health and safety or the environment. “Corrective action” includes but is not limited to excavation of an underground storage tank for purposes of repairing a leak or removal of a tank, removal of contaminated soil, disposal or processing of contaminated soil, cleansing of groundwaters or surface waters, natural biodegradation, institutional controls, and site management practices. “Corrective action” does not include replacement of an underground storage tank. “Corrective action” specifically excludes third-party liability.
3. “Fund” means the Iowa comprehensive petroleum underground storage tank fund.
4. “Nonoperational storage tank” means an underground storage tank in which regulated substances will not be deposited or from which regulated substances will not be dispensed after July 1, 1985.
5. “Operator” means a person in control of, or having responsibility for, the daily operation of the underground storage tank.
6. a. “Owner” means:
(1) In the case of an underground storage tank in use on or after July 1, 1985, a person who owns the underground storage tank used for the storage, use, or dispensing of regulated substances.
(2) In the case of an underground storage tank in use before July 1, 1985, but no longer in use on that date, a person who owned the tank immediately before the discontinuation of its use.
b. To the extent consistent with the federal Resource Conservation and Recovery Act, as amended to January 1, 1994, 42 U.S.C. §6901 et seq., “owner” does not include a person who holds indicia of ownership in the underground storage tank or the tank site property if all of the following apply:
(1) The person holds indicia of ownership primarily to protect that person’s security interest in the underground storage tank or tank site property, where such indicia of ownership was acquired either for the purpose of securing payment of a loan or other indebtedness, or in the course of protecting the security interest. The term “primarily to protect that person’s security interest” includes but is not limited to ownership interests acquired as a consequence of that person exercising rights as a security interest holder in the underground storage tank or tank site property, where such exercise is necessary or appropriate to protect the security interest, to preserve the value of the collateral, or to recover a loan or indebtedness secured by such interest. The person holding indicia of ownership in the underground storage tank or tank site property and who acquires title or a right to title to such underground storage tank or tank site property upon default under the security arrangement, or at, or in lieu of, foreclosure, shall continue to hold such indicia of ownership primarily to protect that person’s security interest so long as subsequent actions taken by that person with respect to the underground storage tank or tank site property are intended to protect the collateral secured by the interest, and demonstrate that the person is seeking to sell or liquidate the secured property rather than holding the property for investment purposes.
(2) The person does not exhibit managerial control of, or managerial responsibility for, the daily operation of the underground storage tank or tank site property through the actual, direct, and continual or recurrent exercise of managerial control over the underground storage tank or tank site property in which that person holds a security interest, which managerial control materially divests the borrower, debtor, owner or operator of the underground storage tank or tank site property of such control.
(3) The person has taken no subsequent action with respect to the site which causes or exacerbates a release or threatened release of a hazardous substance.
7. “Petroleum” means petroleum, including crude oil or any fraction of crude oil which is liquid at standard conditions of temperature and pressure (60 degrees Fahrenheit and fourteen and seven-tenths pounds per square inch absolute).

However, “regulated substance” does not include a substance regulated as a hazardous waste under the Resource Conservation and Recovery Act of 1976. Substances may be added or deleted as regulated substances by rule of the commission pursuant to section 455B.474.
