35 Ill. Adm. Code 724.242
Cost Estimate for Closure
Section 724.242Â Cost
Estimate for Closure
a)Â Â Â Â Â Â Â Â The owner or operator must have detailed a written estimate,
in current dollars, of the cost of closing the facility in accordance with the
requirements in Sections 724.211 through 724.215 and applicable closure
requirements in Sections 724.278, 724.297, 724.328, 724.358, 724.380, 724.410,
724.451, 724.701 through 724.703, and 724.1102.
1)Â Â Â Â Â Â Â Â The estimate must equal the cost of final closure at the point
in the facility's active life when the extent and manner of its operation would
make closure the most expensive, as indicated by its closure plan (see Section
724.212(b)).
2)Â Â Â Â Â Â Â Â The closure cost estimate must be based on the costs to the
owner or operator of hiring a third party to close the facility. A third party
is a party who is neither a parent nor a subsidiary of the owner or operator.
(See definition of parent corporation in Section 724.241(d).)Â The owner or
operator may use costs for on-site disposal if the owner or operator
demonstrates that on-site disposal capacity will exist at all times over the life
of the facility.
3)Â Â Â Â Â Â Â Â The closure cost estimate must not incorporate any salvage
value that may be realized with the sale of hazardous wastes, or non-hazardous
wastes if permitted by the Agency pursuant to Section 724.213(d), facility
structures or equipment, land, or other assets associated with the facility at
the time of partial or final closure.
4)Â Â Â Â Â Â Â Â The owner or operator must not incorporate a zero cost for
hazardous wastes, or non-hazardous wastes if permitted by the Agency pursuant
to Section 724.213(d), that might have economic value.
b)Â Â Â Â Â Â Â Â During the active life of the facility, the owner or operator
must adjust the closure cost estimate for inflation within 60 days prior to the
anniversary date of the establishment of the financial instruments used to
comply with Section 724.243. For owners and operators using the financial test
or corporate guarantee, the closure cost estimate must be updated for inflation
within 30 days after the close of the firm's fiscal year and before submission
of updated information to the Agency as specified in Section 724.243(f)(3). The
adjustment may be made by recalculating the maximum costs of closure in current
dollars, or by using an inflation factor derived from the annual Implicit Price
Deflator for Gross National Product (Deflator) as published by the U.S.
Department of Commerce in its Survey of Current Business, as specified in
subsections (b)(1) and (b)(2). The inflation factor is the result of dividing
the latest published annual Deflator by the Deflator for the previous year.
1)Â Â Â Â Â Â Â Â The first adjustment is made by multiplying the closure cost
estimate by the inflation factor. The result is the adjusted closure cost
estimate.
2)Â Â Â Â Â Â Â Â Subsequent adjustments are made by multiplying the latest
adjusted closure cost estimate by the latest inflation factor.
BOARD NOTE:Â The table of
Deflators is available as Table 1.1.9.,"Implicit Price Deflators for Gross
Domestic Product", in the National Income and Product Account Tables,
published by U.S. Department of Commerce, Bureau of Economic Analysis, National
Economic Accounts, available on-line at the following web address:Â www.bea.gov/national/nipaweb/Table
View.asp?SelectedTable=13&FirstYear=2002&LastYear=2004&Freq=Qtr.
c)Â Â Â Â Â Â Â Â During the active life of the facility the owner or operator
must revise the closure cost estimate no later than 30 days after the Agency
has approved the request to modify the closure plan, if the change in the
closure plan increases the cost of closure. Â The revised closure cost estimate
must be adjusted for inflation, as specified in subsection (b).
d)Â Â Â Â Â Â Â Â The owner or operator must keep the following at the facility
during the operating life of the facility:Â the latest closure cost estimate
prepared in accordance with subsections (a) and (c) and, when this estimate has
been adjusted in accordance with subsection (b), the latest adjusted closure
cost estimate.
