				until released from this requirement by demonstrating compliance with subrules

				current version of department Form 542-8090, Sanitary Landfill Financial

				professional engineer, of the cost of hiring a third party to close the IMF
				landfill in accordance with the closure plan as required by subrules 115.26(13)
				and 115.13(10). Such estimate must be available at any time during the active
				life of the landfill.
(1) The cost estimate
				must equal the cost of closing the IMF landfill at any time during the
				permitted life ofthe facility when the extent and manner of its operation would
				make closure the most expensive.
(2) The costs contained in the third-party
				estimate for closure must be accurate and reasonable when compared to the cost
				estimates used by other similarly situated landfills in Iowa.
(3) During the active life ofthe landfill,
				the owner or operator must annually adjust the closure cost estimate for
				inflation.
(4) The owner or
				operator must, annually or at the time of application for a permit amendment
				that increases closure costs, whichever occurs first, increase the closure cost
				estimate and the amount of financial assurance provided if changes to the
				closure plan or IMF landfill conditions increase the maximum cost of closure at
				any time during the remaining active life of the facility.
(5) The owner or operator may reduce the
				amount of financial assurance for closure if the most recent estimate of the
				maximum cost of closure at any time during the active life of the facility is
				less than the amount of financial assurance currently provided. Prior to the
				reduction, the owner or operator must submit to the department the
				justification for the reduction of the closure cost estimate and the updated
				documentation required by paragraphs 115.31(3)
"a"
to
"e"
and receive department approval for the reduction.
				Approval or denial shall be issued within 30 days of receipt ofthe reduction
				request.

				estimate submitted to the department must include the site area subject to
				closure and account for at least the following factors determined by the
				department to be minimal necessary costs for closure:
