1. This chapter is entitled the "Iowa Comprehensive Petroleum Underground Storage Tank Fund Act".
2. This chapter applies to petroleum underground storage tanks for which an owner or operator is required to maintain proof of financial responsibility under federal or state law, from the effective date of the regulation of the federal environmental protection agency governing that tank, and not from the effective compliance date, unless the effective compliance date of the regulation is the effective date of the regulation. An owner or operator of a petroleum underground storage tank required by federal or state law to maintain proof of financial responsibility for that underground storage tank is subject to this chapter and chapter 424.
a. As of May 5, 1989, tanks excluded by the federal Resource Conservation and Recovery Act, subtitle I, included the following:
(1) A farm or residential tank of one thousand one hundred gallons or less capacity used for storing motor fuel for noncommercial purposes.
(2) A tank used for storing heating oil for consumptive use on the premises where stored.
(3) A septic tank.
(4) A pipeline facility, including gathering lines, regulated under any of the following:
(a) The federal Natural Gas Pipeline Safety Act of 1968.
(b) The federal Hazardous Liquid Petroleum Pipeline Safety Act of 1979.
(c) State laws comparable to the provisions of the law referred to in subparagraph subdivision (a) or (b).
(5) A surface impoundment, pit, pond, or lagoon.
(6) A storm water or wastewater collection system.
(7) A flow-through process tank.
(8) A liquid trap or associated gathering lines directly related to oil or gas production and gathering operations.
(9) A storage tank situated in an underground area, such as a basement, cellar, mine working, drift, shaft, or tunnel, if the storage tank is situated upon or above the surface of the floor to permit inspection of its entire surface.
b. As of May 5, 1989, tanks exempted or excluded by United States environmental protection agency financial responsibility regulations, 40 C.F.R. § 280.90, included the following:
(1) Underground storage tank systems not in operation on or after the applicable compliance date.
(2) Those owned or operated by state and federal governmental entities whose debts and liabilities are the debts and liabilities of a state or the United States.
(3) Any underground storage tank system holding hazardous wastes listed or identifiable under subtitle C of the federal Solid Waste Disposal Act, or a mixture of such hazardous waste and other regulated substances.
(4) Any wastewater treatment tank system that is part of a wastewater treatment facility regulated under section 307(b) or 402 of the federal Clean Water Act.
(5) Equipment or machinery that contains regulated substances for operational purposes such as hydraulic lift tanks and reservoirs and electrical equipment tanks.
(6) Any underground storage tank system whose capacity is one hundred ten gallons or less.
(7) Any underground storage tank system that contains a de minimis concentration of regulated substances.
(8) Any emergency spill or overflow containment underground storage tank system that is expeditiously emptied after use.
(9) Any underground storage tank system that is part of an emergency generator system at nuclear power generation facilities regulated by the nuclear regulatory commission under 10 C.F.R. pt. 50, appendix A.
(10) Airport hydrant fuel distribution systems.
(11) Underground storage tank systems with field- constructed tanks.
c. If and when federal law changes, the department of natural resources shall adopt by rule such additional requirements, exemptions, deferrals, or exclusions as required by federal law. It is expected that certain classes of tanks currently exempted or excluded by federal regulation will be regulated by the United States environmental protection agency in the future. A tank which is not required by federal law to maintain proof of financial responsibility shall not be subject to department of natural resources rules on proof of financial responsibility.
