Cost Estimate for Post-Closure Care
Section 724
Section 724.244Â Cost
Estimate for Post-Closure Care
a)Â Â Â Â Â Â Â Â The owner or operator of a disposal surface impoundment,
disposal miscellaneous unit, land treatment unit, or landfill unit or the owner
or operator of a surface impoundment or waste pile required under Sections
724.328 or 724.358 to prepare a contingent closure and post-closure plan must have
a defined written estimate, in current dollars, of the annual cost of
post-closure monitoring and maintenance of the facility in accordance with the
applicable post-closure regulations in Sections 724.217 through 724.220,
724.328, 724.358, 724.380, 724.410, and 724.703.
1)Â Â Â Â Â Â Â Â The post-closure cost estimate must be based on the costs to
the owner or operator of hiring a third party to conduct post-closure care
activities. 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)).
2)Â Â Â Â Â Â Â Â The post-closure cost estimate is calculated by multiplying
the annual post-closure cost estimate by the number of years of post-closure
care required under Section 724.217.
b)Â Â Â Â Â Â Â Â During the active life of the facility, the owner or operator must
adjust the post-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 724.245. For owners or operators using the financial test
or corporate guarantee, the post-closure cost estimate must be updated for
inflation within 30 days after the close of the firm's fiscal year and before
the submission of updated information to the Agency, as specified in Section
724.245(f)(5). The adjustment may be made by recalculating the post-closure
cost estimate in current dollars or by using an inflation factor derived from
the annual Implicit Price Deflator for Gross National Product, 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 post-closure
cost estimate by the inflation factor. The result is the adjusted post-closure
cost estimate.
2)Â Â Â Â Â Â Â Â Subsequent adjustments are made by multiplying the latest
adjusted post-closure cost estimate by the latest inflation factor.
c)Â Â Â Â Â Â Â Â During the active life of the facility the owner or operator must
revise the post-closure cost estimate within 30 days after the Agency has
approved a request to modify the post-closure plan if the change in the
post-closure plan increases the cost of post-closure care. The revised
post-closure cost estimate must be adjusted for inflation, as specified in
Section 724.244(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 post-closure cost
estimate prepared in accordance with Section 724.244(a) and (c) and, when this
estimate has been adjusted in accordance with Section 724.244(b), the latest
adjusted post-closure cost estimate.
